Description

  The present invention relates to a refrigeration apparatus that freezes a non-frozen product using a cooling liquid. In particular, the present invention relates to a continuous refrigeration type refrigeration apparatus in which a transporter filled with an object to be frozen is frozen in a cooling liquid while being transported.

  In the prior art, there are various methods for freezing meat, vegetables and the like that are to be frozen. For example, there is an air refrigeration (air blasting) system in which the air cooled by a cooler is circulated in the warehouse so that the object is frozen. In addition, there is a liquid freezing (brine freezing) method in which a housing containing an object to be frozen is submerged in a cooling liquid tank filled with a cooling liquid and frozen. In any case, a batch type apparatus has been used in many cases.

FIG. 11 is a schematic view of a conventional batch type liquid refrigeration type refrigeration apparatus.
As the cooling liquid, there is a casing in which the object to be frozen is stored in multiple stages in a cooling liquid tank filled with a cooling liquid made of a calcium chloride aqueous solution or an alcohol aqueous solution called a brine solution that does not freeze even at a cooling temperature. Submerge and freeze. The cooling liquid is cooled via a cooling coil provided at the bottom of the cooling liquid tank, and the temperature in the cooling liquid tank is made uniform by being stirred and flow-promoted by a stirrer.
However, since this batch-type liquid refrigeration apparatus is not a continuous process, it has a small processing capacity and is not suitable for commercial refrigeration for freezing a large amount of non-frozen products. In order to increase the processing capacity in a batch system, it is necessary to enlarge the cooling liquid tank excessively and sink a large amount of the housing at once.
Therefore, in the prior art, although there are few examples, a continuous processing type refrigeration apparatus has been developed in which objects to be frozen are conveyed one after another and continuously subjected to freezing treatment.

FIG. 12 is a diagram showing a continuous refrigeration system refrigeration apparatus using a conveyor that travels in a liquid under a cooling water draft, disclosed in Japanese Patent Application Laid-Open No. 2000-55526.
As shown in FIG. 12, in the continuous refrigeration system refrigeration apparatus disclosed in Japanese Patent Laid-Open No. 2000-55526, a conveyor 66 travels in the liquid below the draft line of the cooling liquid 54 filled in the refrigeration tank 52. The object to be frozen 58 is placed on a conveyor 66 that travels from an insertion port 68 and is input to the freezing tank 52. After being immersed in the cooling liquid 54 for a certain period of time, the object to be frozen 58 is extracted from the extraction port 70. It is a mechanism. The endless track conveyor 66 is continuously operated. In addition, since the individual items to be frozen pass through the cooling liquid in the same path from the inlet 68 to the outlet 70, the quality uniformity of the frozen product is also improved.

JP 2000-55526 A

However, there is a problem to be improved in the continuous refrigeration processing type refrigeration apparatus using a conveyor that travels in the liquid under the draft of the cooling liquid disclosed in Patent Document 1 described in the related art.
As shown in FIG. 12, this refrigeration apparatus uses a conveyor that travels in the liquid below the cooling water draft, and the endless conveyor settles from outside the cooling liquid tank into the cooling liquid tank. Then, after traveling in the liquid for a predetermined distance, a trajectory that is pulled out of the cooling liquid tank again is drawn. Therefore, it is pulled up with a large amount of cooling liquid adhering to the periphery of the object to be frozen, the upper surface of the endless conveyor, the lower surface of the endless conveyor, and the like. Therefore, a large amount of the cooling liquid is taken out of the cooling liquid tank, and a small amount is consumed without returning to the cooling liquid tank. Before and after the turn-up end point, the cooling liquid drops directly from the endless conveyor passing through the air, or contacts the drive mechanism of the endless belt before and after the turn-up end point, and the cooling liquid drops from there. As a result of falling or taking out the object to be frozen, the cooling liquid adhering to the object to be frozen is taken out and the amount of cooling liquid consumed without returning to the cooling liquid tank increases. End up. In particular, in the continuous refrigeration processing type refrigeration apparatus disclosed in Patent Document 1, the object to be transported is merely placed on a conveyor, and the pulling angle from the cooling liquid tank to the outside of the cooling liquid tank is shallow. It is assumed that the amount of the cooling liquid attached to the endless conveyor and drawn out is large.

  Therefore, in order to solve the above-mentioned problem, the present invention is a cooling device that has been consumed in a large amount in a conventional refrigeration apparatus using a conveyor that travels in a liquid under a cooling water draft. An object of the present invention is to provide a continuous refrigeration type refrigeration apparatus that can operate at a low cost by reducing the amount of liquid consumed. It is another object of the present invention to provide a refrigeration apparatus in which the scale of the apparatus can be kept compact while adopting a continuous refrigeration treatment method.

To achieve the above object, a continuous refrigeration type refrigeration apparatus of the present invention is a refrigeration apparatus that freezes an object to be frozen using a cooling liquid, and a cooling liquid tank filled with the cooling liquid, A plurality of transporters having a frame that can support the object to be frozen in an internal space, and an opening through which the cooling liquid enters the internal space if immersed in the cooling liquid tank; An endless moving body that is a moving belt or wire, a transport mechanism that moves while supporting the endless moving body, and a suspension connecting member that is intermittently attached to the endless moving body and suspends the transporter The cooling liquid tank in which the endless track of the endless moving body enters from the outside of the starting end of the cooling liquid tank, travels near the waterline of the cooling liquid tank, and exits outside the end of the cooling liquid tank Orbit and other orbits Wherein, said transporter filled with the frozen food is a continuous freezing type refrigeration apparatus running at immersion state under waterline of the cooling liquid bath in the cooling liquid bath trajectory.
Furthermore, in the above configuration, in the process of lifting the transporter, that is, in the process of transporting the transporter from the immersion state to the air under the draft of the cooling liquid tank, air is sprayed onto the transporter and adheres to the transporter. The structure provided with the blow apparatus which blows off the cooling liquid currently blown into the cooling liquid tank and returns to the cooling liquid tank is preferable.

  According to the said structure, it is suitable for the industrial use which freeze-processes a lot of to-be-cooled objects as a continuous freezing processing system, and the dissipated amount of the cooling liquid may be small. The conventional continuous refrigeration system refrigeration system is driven with the entire conveyor submerged in the cooling liquid, and the belt on which the object to be frozen is placed is pulled up from the cooling liquid, so that a large amount of cooling can be performed. Although the amount of liquid that was drawn up and dissipated along with the belt was large, in the present invention, the endless moving body travels on the waterline of the cooling liquid tank and adheres to the cooling liquid belt together. It will not be withdrawn. Below the draft line of the cooling liquid tank is only the transporter immersed through the suspended connecting member. Moreover, since the cooling liquid adhering to the transport device is blown away in a direction returning to the cooling liquid tank by the blow device, the cooling liquid adhering to the transport device or the object to be frozen can be recovered. .

  Next, as a device for accommodating the entire apparatus in a compact manner, a configuration in which a processing tank for performing a physical process or a chemical process in a heating tank, a cleaning tank, a sterilization tank, a second cooling liquid tank, or the like can be provided in a circular orbit. It is. By performing physical treatment or chemical treatment before and after the freezing treatment, it is possible to meet various requirements as an automatic machine.

  In addition, in order to raise freezing efficiency, it can be set as the structure provided with the some opening-and-closing lid which can be opened and closed on the upper surface, enclosing the said liquid tank for cooling with a heat insulating body. Since the cooling liquid is considerably cooler than the outside air, it is better not to conduct heat from the outside to the cooling liquid tank. Therefore, the entire apparatus is covered with a heat insulator. Here, in order to facilitate access to the apparatus such as maintenance, it is preferable that the upper surface of the heat insulator has a plurality of open / close lid structures that can be opened and closed independently.

Here, the structure of the suspended connecting member and the transporter will be described.
At least two types of suspension connection members and transporters are possible as described below.
The first is a structure in which the transporter is a detachable gondola-type transporter that can be attached to and detached from the endless belt or the endless wire via the suspension connection member.
In other words, the transporter can be attached or detached via the suspension connection member, and the transporter is detachably suspended from the endless moving body.
The detachable gondola type transporter in a state where the object to be frozen is filled is attached to the suspension connecting member at the attachment work place and point and suspended. On the other hand, the detachable gondola-type transporter is removed from the suspended connecting member and collected at a point to be the removal work site.

  In addition, since attachment and detachment of the detachable gondola type transporter may be heavy, it may be difficult to manually lift and lower the detachable gondola type transporter filled with the object to be frozen. Therefore, an attachment lifting device is installed at a point to be an attachment work place and the detachable gondola type transporter is raised and lowered, and a removal lift device is installed at a place to be frozen to be an attachment work place and a detachable gondola type transporter is installed. It lifts and lowers to facilitate attachment / detachment work of the detachable gondola type transporter.

The second is a structure in which the transporter is a trolley transporter fixed to an endless belt or an endless wire via a suspended connecting member.
In other words, in the flow of continuous refrigeration, the transporter is not attached to or removed from the endless belt or endless wire, but the trolley type transporter is always suspended in the motion of the endless belt or endless wire. It is. Of course, it is possible to remove the trolley type transporter from the suspended connecting member at the time of maintenance or trouble.
In the case of the trolley type transporter, the work to be frozen is packed into the trolley type transporter at the place where the material to be frozen is loaded, and traveling is started in a state where the material to be frozen is filled. On the other hand, the object to be frozen is taken out from the trolley type transporter at the place where the object is to be frozen and collected.

According to the continuous refrigeration processing type refrigeration apparatus according to the present invention, the continuous refrigeration processing method is suitable for industrial applications in which a large amount of objects to be cooled is refrigerated, and the amount of cooling liquid dissipated is small. The present invention relates to a transporter in which an endless moving body such as an endless belt or an endless wire is running on the water line of the cooling liquid tank, and the water line under the cooling liquid tank is immersed through a suspended connecting member. However, since the cooling liquid adhering to the conveyance device in the process of lifting the conveyance device is blown away in the direction returning to the cooling liquid tank by the blow device, the cooling liquid adhering to the conveyance device is recovered. It is possible.
In addition, a heating tank, a cleaning tank, a sterilization tank, a second cooling liquid tank, and other processing tanks for performing a physical process or a chemical process can be provided in the orbit, thereby providing more various processes. it can.

Hereinafter, examples of the continuous refrigeration type refrigeration apparatus of the present invention will be described. The present invention is not limited to these examples.
The first embodiment is an example in which the cooling liquid tank 110 is provided only in the forward path of the round-trip path of the endless track. The transporter is an example of a detachable gondola transporter.
The second embodiment is an example in which the cooling liquid tank 110 is provided on the forward path and the return path in the endless track. The transporter is a trolley transporter.

FIG. 1 is a diagram illustrating a basic configuration of a continuous refrigeration-type refrigeration apparatus according to the present invention according to a first embodiment.
The top view of FIG. 1 is a plan view, the middle view of FIG. 1 is a view showing the inside of the cooling liquid tank 110 with the opening / closing lid on the top surface of the heat insulator 160 removed, and the bottom view of FIG. 1 is a side view. Yes. In the lower diagram of FIG. 1, the state of the endless track of the endless moving body 130 and the state of the transporter inside the cooling liquid tank 110 are shown by a partial cross-sectional view so as to be easily understood. In either case, the structure is simply drawn so that the principle of operation is easy to understand.

  As shown in FIG. 1, the continuous refrigeration processing type refrigeration apparatus 100 of the present invention includes a cooling liquid tank 110, a cooling liquid 120, an endless moving body 130, a transporter 140, a suspended connecting member 150, a heat insulating body 160, The blower 170, the lifting device 180, and the transporter rack 190 are provided. In addition, a transporter attachment location S and a transporter removal location T are also shown. In FIG. 1, the transporter 140 is simply shown as a simple housing.

The cooling liquid tank 110 is a container filled with the cooling liquid 120.
There is a transporter attachment point S outside the starting end of the cooling liquid 120 and a transporter removal point T outside the terminal end.
The length L of the cooling liquid tank 110 may be long enough to secure a time T for cooling the object to be cooled to a predetermined temperature with a predetermined temperature gradient. In terms of the relationship with the speed S of the endless wire moving along the endless track, the relationship of L ≧ S · T is satisfied. Here, the speed S of the endless wire will be described later.

  In the configuration of the first embodiment, the cooling liquid tank 110 is provided only in the forward path of the endless track, but the example in which the second cooling liquid tank 110 is provided in the return path is an example. The second embodiment will be described.

  As a cooling mechanism for the cooling liquid tank 110, a cooling coil (not shown) is provided at the bottom of the cooling liquid tank 110. The cooling coil corresponds to an evaporator that absorbs heat in the cooling mechanism, and other members such as a compressor in the cooling mechanism are provided outside and are not shown. It is assumed that the cooling coil has an ability to cool the cooling liquid 120 in the cooling liquid tank 110 to a predetermined temperature.

The homogenization of the temperature of the cooling liquid 120 will be described.
Although a large amount of the cooling liquid 120 is accumulated according to the capacity of the cooling liquid tank 110, it is necessary that the cooling effect by the cooling coil be uniformly given to the cooling liquid 120. In the configuration of the present invention, the transporter 140 is appropriately stirred because the cooling liquid 120 is immersed and travels and moves. However, if necessary, the cooling liquid 120 is stirred in the cooling liquid tank 110. The structure which installs a stirrer (not shown) may be sufficient.

Next, the cooling liquid 120 will be described.
The cooling liquid 120 may be any liquid that has a freezing temperature lower than the temperature at which the object to be frozen is cooled, but is preferably one that ensures stability, safety, and the like. For example, a cooling liquid composed of a calcium chloride aqueous solution or an alcohol aqueous solution called a brine solution may be used. The cooling liquid 120 is cooled via a cooling coil 113 provided at the bottom of the cooling liquid tank 110.

The endless moving body 130 is a moving body that moves along an endless track. For example, there are endless belts and endless wires connected in a circular manner. The following is described as an example in which an endless wire is arranged on an endless track, but the same applies to an endless belt.
The endless track travels near the waterline of the cooling liquid tank 110 from the transporter attachment point S outside the starting end 111 of the cooling liquid tank 110 and the transporter is removed from the end 112 of the cooling liquid tank 110. It includes an outward trajectory that reaches T and a return trajectory that returns from the transporter removal point T to the transporter attachment point S. In this example, the cooling liquid tank 110 or the like is not provided in the return path, and is a space in which the endless moving body 130 moves with the removable gondola type transporter removed.

The traveling height of the cooling liquid 120 in the cooling liquid tank 110 of the endless moving body 130 on the draft line is smaller than the length of the suspension connection member 150, and at least the tip of the suspension connection member 150 is from the draft line of the cooling liquid 120. It is located below.
In addition, in order to suspend many conveyance devices 140, mechanical strength is calculated | required. A reinforced belt having a strong structural strength is preferable for a belt, and a steel wire is preferable for a wire.

  The endless moving body 130 travels with the power of a transport mechanism (not shown), and moves around in a stable posture while being supported by a roller or the like arranged on a track provided by the transport mechanism.

  In the transport mechanism, a support such as a roller is disposed along the orbit of the endless moving body 130, and the endless moving body 130 runs around while gripping the endless moving body 130. A rotating body to which an appropriate torque is given by a motor or the like is disposed, and a driving force is given to the endless moving body 130.

The transporter 140 has a frame shape with a frame that can support the object to be frozen in the internal space, but if immersed in the cooling liquid tank, an opening through which the cooling liquid enters the internal space from the periphery is secured. ing.
Although there are various shapes of the transporter 140, it is sufficient that there is a frame that can support the object to be frozen in the internal space, and it is sufficient if the cooling liquid 120 enters and is immersed from the surroundings. Simple examples include a gage surrounded by a grid, a box with many openings.

  In the first embodiment, the transporter 140 is a detachable gondola-type transporter, and is detachably connected to the endless moving body 130 via a suspension connection member 150. A transporter 140 which is a detachable gondola transporter is attached at a transporter attachment point S outside the starting end 111 of the cooling liquid tank 110 and is removed at a transporter removal point T outside the terminal end 112 of the cooling liquid tank 110. The flow of the continuous refrigeration process with attachment / detachment will be described later.

A plurality of transporters 140 are arranged along an endless track. Here, it is assumed that N transporters 140 are arranged on an outward path of an endless track. The N transporters 140 are transported by the transport mechanism while being attached to the endless moving body 130.
Due to the driving of the transport mechanism, the transporter 140 attached at the transporter attachment point S gradually descends from the transporter attachment point S and sinks under the draft of the cooling liquid 120 in the cooling liquid tank 110, at least. When the object to be frozen is immersed in the cooling liquid 120, it travels through the cooling liquid tank 110, and gradually rises near the transporter removal point T, so that the cooling liquid 120 of the cooling liquid tank 110 is cooled. It is lifted from the water line and reaches the transporter removal point T.

  The suspension connection member 150 is a member that connects the endless moving body 130 and the transporter 140. Although the connection mechanism of the suspension connection member 150 is not particularly limited, it is a mechanism for connecting with a connection tool provided at the upper part on the transporter 140 side. For example, there is a combination in which one of the connection tool on the transporter 140 side and the suspension coupling member 150 is a hook and the other is a ring, and one is a fitting male member and the other is a fitting female member.

  The suspension connection member 150 is intermittently attached to the endless moving body 130 at predetermined intervals. If the transporter 140 is connected to the suspended connection member 150 of the endless moving body 130 one after another in the order of arrival, the transporter 140 is arranged on the endless moving body 130 at predetermined intervals.

  The heat insulator 160 covers the upper surface and the periphery of the cooling liquid tank 110. It is preferable to use a material with high heat insulating properties. In this example, the upper surface has a plurality of open / close lid structures that can be opened and closed independently. In some cases, it may be necessary to access the cooling liquid tank 110 such as confirmation during work and recovery processing of defects, and the problem location of the cooling liquid tank 110 can be immediately accessed by an openable type. In addition, the opening / closing lid structure facilitates regular maintenance such as cleaning.

Next, the blower 170 will be described.
The blow device 170 is a device that injects air at a predetermined pressure. The location where the blower 170 is arranged is slightly in front of the transporter removal point T. The transporter 140 is withdrawn from the cooling liquid 120 in the cooling liquid tank 110, is lifted into the air, and is on the way to the return end. Air is sprayed onto the transporter 140 while being lifted into the air. The cooling liquid 120 adhering to the transporter 140 is blown off and returned to the cooling liquid tank 110.
By the function of the blower 170, the cooling liquid 120 adhering to the transporter and the object to be frozen can be collected at the time of lifting, and the amount of the cooling liquid 120 that is dissipated can be reduced.

Next, the lifting device 180 will be described.
The lifting device 180 is a device that lifts and lowers the detachable gondola type transporter 140. A structure in which the work table is raised and lowered by an operator's operation is preferable. Easy attachment and detachment of gondola type transporters.
The installation places of the lifting / lowering device 180 are a transporter attachment location S and a transporter removal location T.
In this example, what is installed at the transporter attachment location S is an attachment lifting device 180S, and what is installed at the transporter removal location is a removal lifting device 180T. A folded portion of the endless moving body 130 is located on the attachment lifting device 180S. Similarly, the folded portion of the endless moving body 130 is located on the removal lifting device 180T.

  The transporter rack 190 is a shelf that stores the transporter 140 and is disposed adjacent to the transporter attachment point S and the transporter removal point T. The transporter rack 190S disposed at the transporter mounting location S is used to deliver the transporter 140 used for mounting the endless moving body 130 at the transporter mounting location S. Further, the transporter rack 190T disposed at the transporter removal point T accepts the transporter 140 obtained by the removal work from the endless moving body 130 at the transporter removal point T.

In this example, the height of the transporter 140 in the transporter rack 190S disposed at the transporter mounting location S is substantially the same as the height of the work table of the lifting device 180S at the transporter mounting location S. If the transporter 140 in 190S is moved so as to slide, it moves to the work table of the lifting device 180S. In order to facilitate the sliding movement of the transporter 140 in the transporter rack 190S, a structure in which bearings or the like are prepared on the shelf floor is also possible.
Similarly, in this example, the height of the transporter 140 in the transporter rack 190S arranged at the transporter removal point T is substantially the same as the height of the lifting / lowering device 180ST work table at the transporter removal point T.

The above is a brief description of each component.
Next, the flow of the continuous refrigeration process with attachment / detachment of the detachable gondola-type transporter 140 will be described.

In this example, it is assumed that 30 detachable gondola type transporters 140 are attached in the outward path of the endless moving body 130.

  The state of FIG. 4B is a state in which exactly one cycle has elapsed from the state of FIG. 2A, and is a state in which the order has moved one by one in the order of each detachable gondola type transporter 140An. It can be seen from the flow of FIGS. 2 to 4 that the work for one cycle is completed. By repeating the flow of FIG. 2 to FIG. 4, the attachment work of the detachable gondola type transporter 140 at the transporter attachment point S is sequentially performed.

Next, the removal work of the detachable gondola type transporter 140 at the transporter removal point T will be described.
In the state of FIG. 5A, the first detachable gondola type transporter 140A1 in the detachable gondola type transporter 140 has come to the transporter removal point T, and then the detachable gondola type transporter 140A2 is approaching. The work table of the lifting / lowering device 180T is immediately below the transporter removal point T, and is prepared for receiving the removable gondola transporter 140A1.

  Next, as shown in FIG. 5B, the work table of the lifting / lowering device 180T is raised and stopped when the weight of the detachable gondola type transporter 140A1 is completely supported.
