DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique for drying livestock products, agricultural products, forest products, marine products and other various products.

[0002]

2. Description of the Related Art Drying means an operation for removing a liquid (usually water) from a wet solid. Techniques such as heat drying and freeze drying have conventionally been used for biochemical substances, pharmaceuticals and foods. , Wood and various other fields. Particularly in the field of foods, drying techniques have been applied since ancient times to preserve foods. The dried food is used as it is or after being immersed in water or the like and returned to its original state. However, it is not an exaggeration to say that, for example, the return of the original dried vegetables to the original state is very imperfect and the original flavor of the vegetables is impaired at all. It is currently limited. Also, in the case of drying meat and fish, it is very difficult to obtain an excellent flavor by a conventional method, and in many cases, products tend to vary. Furthermore, in drying rice and other grains, conventional drying techniques often impair the flavor of the grains. In particular, in the case of rice, the subtle texture of the rice often determines whether the rice is good or bad, so the quality of the drying technology may affect the sales of rice itself. By the way, drying essentially involves the flow of a liquid (water) inside a solid, and proper diffusion of the liquid needs to occur in the solid. That is, the drying of the solid depends on the requirements of the flow of the liquid inside the solid, the diffusion of the liquid, the internal pressure gradient due to the contraction, the continuous vapor-liquid flow due to the temperature gradient, the diffusion, the penetration, etc. It is considered that the above-mentioned requirements cannot be properly balanced in the prior art, especially in the field of drying in the food field, and good results could not be obtained. This is considered to be due to the fact that the conventional technology could not precisely set and execute temperature conditions and the like.

FIG. 1 is a perspective view showing a dryer. Reference numeral 1 denotes a sealable dryer having double doors 1a and 1a for storing rice, wheat and other agricultural products, livestock products such as meat, fish products, and marine products such as seaweed. In the room, heat insulating materials are interposed on the upper, lower, left and right outer peripheral walls. Reference numeral 2 denotes a temperature control room provided above the drying room 1 and provided with cooling means. 3 is a decompression / equilibrium heating means provided on the side wall of the heat collection chamber 2, and 15 is an outside air supply means for supplying outside air to the drying chamber 1 as needed. It consists of a pipe that opens outside and an adjustment valve.

FIG. 2 is a longitudinal sectional view of FIG. 1. The decompression / equilibrium heating means 3 provided at the side wall opening of the temperature control chamber 2 includes a propeller fan 4 as a rotating body, an electric motor 5 for rotating the propeller fan 4, And a cover 6 for covering them. One end of the cover 6 opens at the side wall opening of the temperature control chamber 2 described above, and the other end opens inside the temperature control chamber 2. Reference numeral 7 denotes a frictional heat generating portion formed in the rotation area of the propeller fan 4 and in the vicinity thereof, that is, between the propeller fan 4 and the cover 6.
Generates frictional heat due to friction between the air and the air. The temperature control chamber 2 in which a heat insulating material is interposed on the side wall and the bottom has a cooling means 2a therein. The cooling means 2a is a well-known refrigerator which is constituted by a refrigerant flow path 9, a heat exchanger 10, and the like, and operates by ordinary electric control.

Reference numeral 11 denotes a pipe formed between the temperature control chamber 2 and the drying chamber 1. Air (heat medium) set at a predetermined temperature in the temperature control chamber 2 is supplied into the pipe 11. An electric fan 12 is provided for supplying the heat transfer medium, and the pipe section 11 and the electric fan 12 constitute a heat medium transmission unit. Reference numeral 13 denotes an air flow passage formed between the temperature control chamber 2 and the drying chamber 1, and the air in the drying chamber 1 is forcibly exhausted to the atmosphere by the propeller fan 4 via the air flow passage. . Reference numeral 14 denotes a control unit including a temperature sensor, a humidity sensor, a pressure sensor, a microcomputer, and the like. The operation of the cooling means 2a, the propeller fan 4 (the electric motor 5), the electric fan 12, the outside air supply means 15 described later, and the like are controlled by comparing these conditions. Reference numeral 15 denotes outside air supply means for supplying outside air into the drying chamber 1 according to the temperature, humidity, decompression state, and the like in the drying chamber 1.
And is discharged to the outside together with moisture in the drying chamber 1. Although the outside air supply means 15 is shown by a manual valve in the drawing, the introduction of outside air may be controlled by the control means using an automatic control valve.

Next, the operation of this embodiment based on the above configuration will be described. A desired drying target such as vegetables, meat, fish, etc. is stored in the drying chamber 1, and power is supplied to the control means 14 by a control panel (not shown) to control the drying time and drying temperature (temperature in the drying chamber). When the switch is turned on by inputting the data, the propeller fan 4 of the decompression / equilibrium heating means 3 starts to rotate.
The air in the drying chamber 1 and the air in the temperature control chamber 2 are forcibly sucked and exhausted to the outside, and the inside of the room is decompressed, so that the pressure difference between the inside and outside is kept in a substantially constant equilibrium state. When the rotation is continued, the frictional action between the air and the propeller fan 4 is promoted, and frictional heat is generated in the frictional heat generating section 7 to heat the temperature control chamber 2. On the other hand, when the switch is turned on, the cooling means 2a also starts operating to cool the temperature control chamber 2. Thus, the air in the temperature control chamber 2 is set to a predetermined temperature by heating and cooling. And the temperature control room 2 at which the predetermined temperature is reached
The air inside is supplied to the drying chamber 1 by the electric fan 12. As described above, the object to be dried in the drying chamber 1 is dried in the drying chamber 1 under a preset reduced pressure value and temperature.

The temperature, humidity, reduced pressure state, etc. in the drying chamber 2 are as follows:
The control means 14 controls the cooling means 2a and the propeller fan 1
4. It is executed by controlling the operation of the electric fan 12, the outside air supply means 15, and the like. For example, the operation of only the decompression and equilibrium heating means 3 depending on the conditions of the outside air temperature and the set temperature,
When the temperature and the like in the drying chamber 1 can be maintained within the set values, the cooling means 2a does not operate. If the temperature of the drying chamber 1 still exceeds the set temperature even in such a state, the temperature in the drying chamber 1 is controlled by reducing or stopping the rotation of the electric fan 12. Even when the temperature inside the drying chamber 1 rises as described above, the cooling means 2a
Operates to control the temperature of the air in the temperature control chamber 2 to maintain the temperature in the drying chamber 1 at a predetermined value. In addition, although the decompression equilibrium heating means 3 always operates, since the delicate temperature control is required in the drying of food, the cooling means 2a is usually always operated together with the decompression equilibrium heating means 3. In addition, the humidity in the drying chamber 1 becomes higher than the set value and the drying is smooth.
When the condition is not reached, the operation of the control means 14 causes the outside air supply means 15 to introduce outside air into the drying chamber 1. This introduction of fresh air can also be done manually. As described above, the adjustment of the rotation speed of the propeller fan 4 of the reduced-pressure equilibrium heating means 3
By controlling the operation of the cooling means 2b and adjusting the rotation of the electric fan 12 as the transmission means, the drying conditions, especially the temperature, in the drying chamber 1 can be maintained very accurately and precisely according to the characteristics of the material to be dried.

FIG. 3 is a diagram showing an embodiment according to claims 2 and 5 of the present application. In the drawing, a cover body 6 of the decompression / equilibrium heating means 3 shields the propeller fan 4 from the chamber 2 and opens only into the drying chamber 1 through a pipe 6a. Numeral 11 denotes a drying chamber 1 in which air as a heat medium from the temperature control chamber 2 is supplied.

Desired objects to be dried such as vegetables, meat, fish, etc. are stored in the drying chamber 1, and power is supplied to the control means 14 by a control panel (not shown) for drying time and drying temperature (temperature in the drying chamber).
When the switch is turned on by inputting the data, the propeller fan 4 of the decompression / equilibrium heating means 3 starts rotating, and the rotation of the propeller fan 4 as a rotating body causes the drying chamber 1 to rotate.
The inside air is forcibly sucked and exhausted to the outside, and the inside of the drying chamber 1 is decompressed, and the pressure difference between the inside and outside is kept in a substantially constant equilibrium state. When the rotation is continued, the frictional action between the air and the propeller fan 4 is promoted, and frictional heat is generated in the frictional heat generating section 7, and this heat heats the chamber 2 via the cover body 6. On the other hand, when the switch is turned on, the cooling means 2a also starts operating to cool the temperature control chamber 2. Thus, the air in the chamber-2 is set to a predetermined temperature by heating and cooling. Then, the air in the chamber-2 which has reached the predetermined temperature is supplied to the drying chamber 1 through the passage 11 as the pressure in the drying chamber 1 is reduced. As described above, the object to be dried in the drying chamber 1 is dried in the drying chamber 1 based on a preset reduced pressure value and temperature.

The control means 14 controls the cooling means 2a and the propeller fan 1
4. It is executed by controlling the operation of the outside air supply means 15 and the like. For example, when the temperature and the like in the drying chamber 1 can be maintained within the set values by the operation of only the decompression and equilibrium heating means 3 depending on the conditions of the outside air temperature and the set temperature, the cooling means 2a does not operate. When the temperature in the drying chamber 1 rises above a set value, the cooling means 2a operates to adjust the temperature of the air in the temperature control chamber 2 to maintain the temperature in the drying chamber 1 at a predetermined value. In addition, although the decompression equilibrium heating means 3 always operates, since the delicate temperature control is required in the drying of food, the cooling means 2a is usually always operated together with the decompression equilibrium heating means 3. Further, when the humidity in the drying chamber 1 becomes equal to or higher than the set value and drying is not performed smoothly, the outside air supply means 15 introduces outside air into the drying chamber 1 by the operation of the control means 14. This introduction of fresh air can also be done manually.
As described above, the propeller fan 4
By controlling the number of rotations and controlling the operation of the cooling means 2a, the drying conditions in the drying chamber 1, particularly the temperature, can be maintained extremely accurately and precisely according to the characteristics of the material to be dried.

The cooling means 2 a is installed in the upper part of the drying chamber 1, and cool air is supplied into the drying chamber 1 through the passage 11. And
The outside air supply means 15 is installed on a side wall above the drying chamber 1.

Next, the operation of this embodiment and the embodiment of claim 10 will be described together. A desired drying target such as vegetables, meat, fish, etc. is stored in the drying chamber 1, and power is supplied to the control means 14 by a control panel (not shown) to control the drying time and drying temperature (temperature in the drying chamber). When the propeller fan 4 of the decompression / equilibrium heating means 3 starts to rotate, the air in the drying chamber 1 is forcibly sucked by the rotating action of the propeller fan 4 as a rotating body, and The inside of the drying chamber 1 is depressurized, and the pressure difference between the inside and the outside of the chamber is kept in a substantially constant equilibrium state. When the rotation is continued, the frictional action between the air and the propeller fan 4 is promoted, and frictional heat is generated in the frictional heat generating section 7, and this heat heats the drying chamber 1. On the other hand, the cooling means 2
a also starts operating, and the cool air is supplied to the drying chamber 1 through the passage 11 as the pressure in the drying chamber 1 is reduced. Thus, the air in the drying chamber 1 is set to a predetermined temperature by heating and cooling. As described above, the object to be dried in the drying chamber 1 has a predetermined reduced pressure value in the drying chamber 1,
Dried under temperature.

The temperature, humidity, reduced pressure, etc. in the drying chamber 2 are as follows:
The control means 14 controls the cooling means 2a and the propeller fan 1
4. It is executed by controlling the operation of the outside air supply means 15 and the like. For example, when the temperature and the like in the drying chamber 1 can be maintained within the set values by the operation of only the decompression and equilibrium heating means 3 depending on the conditions of the outside air temperature and the set temperature, the cooling means 2a does not operate. When the temperature in the drying chamber 1 rises above the set value, the cooling means 2a operates to adjust the temperature of the air in the drying chamber 1 to maintain the temperature in the drying chamber 1 at a predetermined value. In addition, although the decompression equilibrium heating means 3 always operates, since the delicate temperature control is required in the drying of food, the cooling means 2a is usually always operated together with the decompression equilibrium heating means 3. Further, when the humidity in the drying chamber 1 becomes equal to or higher than the set value and drying is not performed smoothly, the outside air supply means 15 introduces outside air into the drying chamber 1 by the operation of the control means 14. This introduction of fresh air can also be done manually.
As described above, the propeller fan 4
By controlling the number of rotations and controlling the operation of the cooling means 2a, the drying conditions in the drying chamber 1, particularly the temperature, can be maintained extremely accurately and precisely according to the characteristics of the material to be dried.

FIG. 5 is a longitudinal sectional view of a drying apparatus according to the fourth and fifth embodiments. The decompression and equilibrium heating means 3 provided at the side wall opening of the drying chamber 1 includes a propeller fan 4 as a rotating body, An electric motor 5 for rotating the propeller fan 4
And a cover 6 for covering them. One end of the cover 6 opens at the side wall opening of the drying chamber 1 described above, and the other end opens inside the drying chamber 1. Numeral 7 is a frictional heat generating portion formed between the propeller fan 4 rotation area and the vicinity thereof, that is, between the propeller fan 4 and the cover 6, and by the friction between the propeller fan 4 and the air as in the above-described embodiment. Generates frictional heat. The cooling chamber 2 in which a heat insulating material is interposed on the side wall and the bottom has a cooling means 2a therein. The cooling means 2a includes a refrigerant flow path 9, a heat exchanger 10, a transmission path 9b described later, and a heat absorbing fan coil 9a.
And so on. One end of the refrigerant passage 9 is connected to one end of a heat absorbing fan coil 9a installed in the drying chamber 1 via a transmission path 9b on the outward path, and the other end is connected to the heat absorbing fan coil 9 via a transmission path 9b on the return path. Water and other liquids are circulated as a refrigerant by a pump (not shown) which is connected to the other end of 9a. And the transmission line 9 on the outward path side
b orbits around the rotation area of the propeller fan 4,
The friction heat generating portion 7 is formed in contact with the open end of the cover 6 and between the orbiting portion and the propeller fan 4.
Reference numeral 14 denotes a control unit including a temperature sensor, a humidity sensor, a pressure sensor, a microcomputer, and the like. The operation of the propeller fan 4 (the electric motor 5), the cooling means 2a, and the like is controlled by comparing the conditions with the conditions. Reference numeral 15 denotes outside air supply means for supplying outside air into the drying chamber 1 according to the temperature, humidity, reduced pressure state, and the like in the drying chamber 1. Although the outside air supply means 15 is shown by a manual valve in the drawing, the introduction of outside air may be controlled by the control means using an automatic control valve.

Next, the operation of the embodiment will be described. A desired drying target such as vegetables, meat, fish, etc. is stored in the drying chamber 1, and power is supplied to the control means 14 by a control panel (not shown) to control the drying time and drying temperature (temperature in the drying chamber). When the propeller fan 4 of the decompression / equilibrium heating means 3 starts to rotate, the air in the drying chamber 1 is forcibly sucked by the rotating action of the propeller fan 4 as a rotating body, and The inside of the room is depressurized, and the pressure difference between the inside and outside of the room is kept in a substantially constant equilibrium state.
When the rotation is continued, the frictional action between the air and the propeller fan 4 is promoted, so that frictional heat is generated in the frictional heat generating section 7 and the drying chamber 1 is heated. On the other hand, when the switch is turned on, the cooling means 2a also starts operating, and the inside of the drying chamber 1 is cooled by the refrigerant transmission path 9b and the heat absorbing fan 9a. Since the cover 6 of the frictional heat generator 7 is wound around the transmission line 9b for the refrigerant, the balance between heating and cooling can be finely adjusted, and the temperature in the drying chamber 1 can be precisely controlled. As described above, the object to be dried in the drying chamber 1 is dried in the drying chamber 1 based on a preset reduced pressure value and temperature.

The temperature, humidity, reduced pressure state, etc. in the drying chamber 2 are as follows:

The radiator 2 b is attached to the outer wall of the temperature control chamber 2, and is cooled by receiving an exhaust flow from the propeller fan 4 of the decompression / equilibrium heating means 3.
That is, the water whose temperature has increased in the heat exchanger 10 is cooled in the radiator 2b, and is returned to the heat exchanger 10 again to cool the temperature control chamber 2. The other operations of this embodiment are the same as those of the embodiment shown in FIG.

When only the above-mentioned reduced pressure equilibrium heating device is used for drying the material to be dried in the drying chamber, the drying chamber is decompressed to promote drying, but at the same time, the temperature in the chamber is raised to 60 degrees Celsius.
Beyond that, drying must be performed at temperatures above 60 degrees Celsius. However, drying at such relatively high temperatures is not always the best result. What temperature environment is preferable for drying depends on the characteristics of the material to be dried, the application, etc.
15-20 degrees Celsius for fish and vegetables such as green onions, radish, spinach and broccoli are best dried at around 25 degrees Celsius, and dried vegetables obtained at such temperatures should be returned with water. As a result, the quality is not inferior to fresh products. That is, in the case of fresh food, in the drying process,
By drying at a specific temperature for a specific time and then drying at another set temperature for a specific time, a product with excellent flavor can be obtained, but the drying apparatus of the present application sets such complicated drying conditions. , Can be run. Such complicated necessity of drying under drying conditions is also necessary in drying rice seed rice and drying bonito, but the present apparatus can meet such necessity.
