Another advantage of the above embodiment is that in the manufacturing process of the sealed packaging film-coated powder circle, the film-coated powder circle does not need to be dried, and the film-coated powder circle does not need to be frozen, so it can effectively save the sealed packaging film. The energy consumed by the powder circle manufacturing process.

Other advantages of the present invention will be explained in more detail with the following description and drawings.

The embodiments of the present invention will be described below in conjunction with related drawings. In the drawings, the same reference numerals indicate the same or similar elements or method flows.

FIG. 1 is a simplified functional block diagram of a sealed packaging film-coated powder circle production system 100 according to an embodiment of the present invention. The sealed packaging film-coated powder circle production system 100 includes a stirring and forming device 110, a cross-linking reaction device 120, a filtering device 130, a filling device 140, a sealing device 150, a high temperature sterilization device 160, a conveyor belt 170, and a boxing device 180.

Hereinafter, the operation mode of the sealed packaging film-coated powder circle production system 100 will be further described in conjunction with FIGS. 2 to 4. Fig. 2 is a simplified flowchart of a method for manufacturing a sealed package film-coated powder circle according to an embodiment of the present invention. 3 and 4 are schematic diagrams of the simplified operation of the manufacturing method of the sealed packaging film-coated powder circle at different stages of the present invention.

In the process 210, the stirring and forming device 110 can mix, stir, and shape starch, sodium alginate, water, and other one or more predetermined materials in an appropriate ratio to form the shape shown in FIG. 3 A plurality of solid powder round core bodies 310. The outer shape of each solid powder core body 310 may be spherical as illustrated in FIG. 3, or may be various other three-dimensional shapes. As for the size of each solid powder round core body 310, it can be flexibly adjusted according to actual needs.

In practice, the aforementioned starch can be tapioca flour (or called cassava flour), sweet potato flour, lotus root flour, corn flour, potato flour (or commonly known as corn flour), or the aforementioned starches in a certain proportion. mixture. The aforementioned predetermined materials may include various modified starches, thickeners, stabilizers, anti-caking agents for food, and the like that comply with food hygiene regulations. For example, you can add an appropriate amount of Guanhua bean gum, locust bean gum, carrageenan, corn syrup (three cents gum), calderan gum, acacia gum, gellan gum, pectin, and/or CMC viscose ( Sodium carboxymethyl cellulose), as the thickener and stabilizer in the powder core 310. In addition, the weight percentage of the aforementioned sodium alginate in each round core body 310 may be between 0.8 and 2.4 wt%.

In the process 220, the cross-linking reaction device 120 may put a plurality of powder round core bodies 310 into the cross-linking agent solution 330 contained in the container 320 and soak for a predetermined length of time to carry out the crosslinking reaction, so that each The surface of the powder core body 310 is covered with a polymer protective film 342 to thereby produce a plurality of coated powder circles 340 as shown in FIG. 3.

The aforementioned crosslinking agent solution 330 can be implemented with a calcium lactate solution or a calcium chloride solution with a concentration of 0.8% to 2.5% by weight. In this way, during the cross-linking reaction, the calcium ions in the cross-linking agent solution 330 will replace the sodium ions in the sodium alginate and form a bond with the carboxylic acid ions between the sodium alginate molecules. Such a cross-linking reaction will increase the bonding strength between the sodium alginate molecules, transform the sodium alginate into a dense colloidal structure that is not easily soluble in water, and form a polymer protective film 342 covering the entire powder core body 310.

From a certain perspective, the polymer protective film 342 on the surface of each coated powder circle 340 is mainly composed of the sodium alginate component and the crosslinking agent solution near the surface of the powder circle core 310 inside the coated powder circle 340 The calcium ion in 330 is formed by cross-linking reaction. Since the aforementioned cross-linking reaction does not detract from the total amount of sodium alginate, the weight percentage of sodium alginate in each coated powder circle 340 is still approximately 0.8-2.4 wt%.

The polymer protective film 342 covering the outer surface of each film-coated powder circle 340 is not only difficult to dissolve in water, but also has the physical properties of high temperature resistance and can withstand the subsequent high temperature sterilization treatment without being damaged.

If the powder round core body 310 is immersed in the cross-linking agent solution 330 for too short a time, the coating rate and strength of the formed polymer protective film 342 will not be ideal. On the other hand, if the powder round core body 310 is immersed in the crosslinking agent solution 330 for too long, it will not only reduce the overall manufacturing efficiency, but also easily cause the powder round core body 310 to absorb too much moisture and become too soft, even This may cause the powder round core body 310 to burst during the subsequent high-temperature sterilization process.

According to the test results, the predetermined length of time for the powder round core body 310 to be immersed in the crosslinking agent solution 330 is set to be between 15 seconds and 90 seconds (for example, 20 seconds, 30 seconds, 40 seconds, 50 seconds, 60 seconds, 75 seconds). Seconds, etc.), in addition to achieving a better balance between the coverage rate and strength of the polymer protective film 342, and the production efficiency of the coated powder 340, it can also ensure that the powder core 310 is cross-linked Only an appropriate amount of water is absorbed in the agent solution 330 to avoid the problem of vaporization and explosion of the powder core body 310 in the subsequent high temperature sterilization process due to the inhalation of too much water.

In the process 230, the filter device 130 can filter a plurality of coated powder circles 340 from the cross-linking agent solution 330 with various suitable filters, filter pans and other tools.

Please note that although the aforementioned powder round core body 310 will absorb water in the crosslinking agent solution 330 when it is immersed in the crosslinking agent solution 330, since the powder round core body 310 is not immersed in the crosslinking agent solution 330 for a long time, Therefore, the amount of water absorbed by the powder core body 310 is limited. Therefore, when the filtering device 130 filters the coated powder circle 340 from the crosslinking agent solution 330, the powder core body 310 inside the coated powder circle 340 will still be in a solid state.

It can be seen from the foregoing description that the inner core of the film-coated powder circle 340 is a solid powder core body 310, and the outer surface of the film-coated powder circle 340 is covered by the polymer protective film 342.

In the process 240, the filling device 140 can fill the plurality of coated powder circles 340 filtered by the filtering device 130 into one or more high temperature resistant powder circle containers 402 according to a predetermined quantity or weight, so that each powder circle The quantity or weight of the film-coated powder circle 340 in the container 402 meets a predetermined standard. In one embodiment, the filling device 140 can fill a plurality of coated powder circles 340 into each powder circle container 402 at room temperature. In another embodiment, the filling device 140 can use a high-temperature filling method to fill a plurality of coated powder circles 340 into each powder circle container 402 to reduce the pollution of the coated powder circles 340 by harmful substances during the filling process. opportunity.

In the process 250, the sealing device 150 can seal each powder-coated powder container 402 that has been filled and contains a plurality of film-coated powder circles 340 to form one or more sealed packaging film-coated powder circles 410 as shown in FIG. 4. Once the powder circle container 402 completes the sealing process to form a sealed package coated powder circle 410, external bacteria or microorganisms are likely to cause the coated powder circle 340 or the powder circle core 310 inside the coated powder circle 340 to decay. It is difficult to enter the powder round container 402.

In some embodiments, the sealing device 150 can also perform a vacuum operation on the powder round container 402 during the aforementioned sealing procedure, so as to reduce the amount of air inside the sealed package film-coated powder round 410.

In practical applications, the aforementioned powder round container 402 can be realized by various bag-like containers such as heat-resistant bags that can be sealed by machines, and can also be implemented by a variety of glass cans, iron cans, tin cans, and aluminum cans that can be sealed. It can be realized by a kind of tank-shaped container, or can also be realized by various drum-shaped containers such as iron drums, tin drums, stainless steel drums, and plastic drums that can be sealed.

Therefore, the actual form of the aforementioned sealed packaging film-coated powder circle 410 may be a sealed bag, a sealed can, or a sealed barrel.

In the process 260, the high-temperature sterilization device 160 may perform a high-temperature sterilization process on the sealed package film-coated powder circle 410 that has completed the sealing process. For example, as shown in FIG. 4, the high-temperature sterilization device 160 can use a steam generator 420 to generate high-temperature steam 422 with a temperature exceeding 100 degrees Celsius to perform high-temperature sterilization on the sealed packaging film-coated powder 410 placed in the high-temperature sterilization device 160 In order to completely eliminate the bacteria or microorganisms that may be contaminated on the surface and inside of the powder core body 310 of the individual coated powder circle 340 during the aforementioned manufacturing process, which may easily cause the powder circle core body 310 to rot.

In practice, the high-temperature sterilization device 160 can also change the sealed package film-coated powder 410 into boiling water for heating, so as to perform a high-temperature sterilization process on the sealed package film-coated powder 410 using the high temperature of boiling water. Alternatively, the high-temperature sterilization device 160 can also use high-temperature infrared to irradiate the sealed package film-coated powder circle 410, so as to perform a high-temperature sterilization process on the sealed package film-coated powder circle 410.

As mentioned above, the polymer protective film 342 covering the outer surface of each coated powder circle 340 has the physical properties of high temperature resistance, so it can withstand the high temperature in the process 260 without being damaged. Therefore, after the high-temperature sterilization process is completed for the sealed package coated powder circle 410, the polymer protective film 342 can continue to play a protective role, effectively preventing harmful bacteria or microorganisms from entering the powder circle core 310 inside the coated powder circle 340 to reduce Possibility of powder round core body 310 decay

More importantly, when the high temperature sterilization device 160 performs high temperature sterilization on the sealed package coated powder circle 410, the polymer protective film 342 can effectively prevent the coated powder circle 340 from being gelatinized and sticking to each other due to high temperature. The problem. Therefore, after the sealed packaging film-coated powder circle 410 completes the high-temperature sterilization process, the film-coated powder circle 340 in the powder circle container 402 will still be separated from each other, and will not be stuck together.

In contrast, if the aforementioned powder round core body 310 is put into the powder round container 402 and then sealed and subjected to the same high temperature sterilization process, the powder round core body 310 in the powder round container 402 is easily affected by high temperature. Soften, gelatinize, and stick to each other into clumps that cannot be separated. In other words, the powder round core 310 that is not covered by the polymer protective film 342 is not suitable for high-temperature sterilization.

Furthermore, as mentioned above, the inner core of the coated powder circle 340 is a solid powder circle core body 310. The solid powder core body 310 will not vaporize when subjected to the high temperature of the sterilization process. Therefore, when the high temperature sterilization device 160 performs high temperature sterilization on the sealed package coated powder circle 410, it is located in the sealed package coated powder circle. The coating powder circle 340 in 410 will not burst.

Since the aforementioned sealed package film-coated powder circle production system 100 can use a high-temperature sterilization process to sterilize the sealed package film-coated powder circle 410, it is not necessary to add any preservative to the film-coated powder circle 340 to effectively extend the film. The shelf life of the powder circle 340 allows the aforementioned sealed package coated powder circle 410 to be stored directly at room temperature for several months or even more than one year.

In the process 270, the conveyor belt 170 can transport the sealed packaging film-coated powder circle 410 that has completed the high-temperature sterilization treatment to the position of the quality inspection personnel or the automated quality inspection equipment, so that the quality inspection personnel or the quality inspection equipment can cover the aforementioned sealed packaging. The film powder circle 410 undergoes a quality inspection to determine whether the sealed package film-coated powder circle 410 is damaged or incompletely sealed, and other defects that may affect the storage time. If defects are found in the sealed packaging film-coated powder circle 410, it can be directly eliminated, or it can be opened and refilled, sealed, and subjected to the aforementioned high-temperature sterilization process to make a new sealed packaging film-coated powder circle 410 .

During operation, the sealed packaging film-coated powder balls 410 that have passed the quality inspection can be transported to the boxing device 180 using the conveyor belt 170, and the sealed packaging film-coated powder balls 410 can be carried out according to a predetermined quantity or weight by the boxing device 180 Packing operation.

After that, the manufacturer or the relevant downstream industry can proceed to the process 280 to deliver or store the sealed packaging film-coated powder 410 that has passed the quality inspection at room temperature.

Please note that some existing powder round products on the market have an inner and outer two-layer structure. The outer layer is a general powder round material and the inner layer is a liquid or a structure that mixes both liquid and solid particles. If these traditional powder round products with an inner and outer two-layer structure are subjected to a high-temperature sterilization procedure similar to the aforementioned process 260, the liquid in the inner layer of these powder round products will be vaporized due to heat, which will break through the outer structure and cause the powder round. The product bursts.

Therefore, the traditional two-layer structure of the powder circle is not suitable for sterilization by high temperature sterilization. It can only extend the storage time of powder circle products by adding preservatives, but it is difficult to extend the powder circle products without adding preservatives. Save time.

In contrast, although the aforementioned coated powder circle 340 also has an inner and outer two-layer structure, the outer structure of the coated powder circle 340 is a polymer protective film 342, and the inner structure is a solid powder core 310. Therefore, during the high-temperature sterilization process, the solid powder core body 310 located in the inner layer of the coated powder circle 340 will not vaporize, so it will not cause the entire coated powder circle 340 to burst.

It can be seen from the foregoing description that in the process of high-temperature sterilization of the sealed packaging film-coated powder circle 410, the polymer protective film 342 covering the outer surface of each film-coated powder circle 340 can not only withstand high temperatures without being damaged, but also effectively The problem of gelatinization and agglomeration of the coated powder circles 340 due to high temperature is avoided.

Therefore, the powder circle manufacturer can use the high temperature sterilization process to sterilize the sealed package coated powder circle 410, so it is not necessary to add preservatives in the coated powder circle 340 to effectively extend the inside of the sealed package coated powder circle 410 The shelf life of the coated powder round 340.

In addition, the polymer protective film 342 covering the outer surface of each coated powder circle 340 can withstand the temperature of the high-temperature sterilization process without being damaged. Therefore, after the high-temperature sterilization process is completed, the polymer protective film 342 can continue to play a protective role. It effectively prevents harmful bacteria or microorganisms from entering the powder core body 310 inside the coated powder circle 340, thus reducing the possibility of deterioration and decay of the powder core body 310.

Furthermore, since the sealed package coated powder circle 410 is sealed, it can isolate the external harmful substances from polluting the inner coated powder circle 340 during storage or transportation.

Please note that in the aforementioned manufacturing method of FIG. 2, after the coated powder circle 340 is filtered from the crosslinking agent solution 330, until the coated powder circle 340 is filled into the powder circle container 402, the entire manufacturing process is sealed The packaging film-coated powder circle production system 100 does not dry the film-coated powder circle 340, the purpose is to deliberately make the powder core body 310 inside each film-coated powder circle 340 can be kept from the crosslinking agent solution 330 A little bit of water absorbed.

In this way, when the store unpacks the sealed packaging film-coated powder circle 410 in the future, and pours the inner film-coated powder circle 340 into water and heats it for cooking, the film-coated powder circle 340 can absorb enough in less time. Water, so the time required to cook the coated flour balls 340 will be shorter than the time required to cook the traditional flour balls.

On the other hand, in the manufacturing process of the aforementioned sealed package coated powder circle 410, there is no need to spend extra time and electricity to freeze the coated powder circle 340, so the aforementioned manufacturing method of sealed package coated powder circle 410 is not only energy-saving. , But also has good manufacturing efficiency.

Moreover, the use of the aforementioned manufacturing method to manufacture the sealed packaging coated powder circle 410 can ensure that the coated powder circle 340 filled in the powder circle container 402 will not undergo deterioration such as decay, so that the resulting sealed package can be coated Membrane powder round 410 can be stored directly at room temperature for several months or even more than a year. It can also be transported directly at room temperature without storing in the freezing storage equipment, so it can reduce the store’s space for freezing equipment. The demand can also reduce the energy consumption during transportation.

It can be seen from the foregoing description that in the process of producing the sealed packaging film-coated powder circle 410 by the sealed packaging film-coated powder circle production system 100, neither the drying process nor the freezing of the film-coated powder circle 340 is necessary. Therefore, the energy consumed in the process of producing the sealed packaging film-coated powder circle 410 can be effectively saved.
