Description

Technical Field

[0001] The present invention relates to the field of gelatin production, in particular to a sterilization and drying device for producing edible gelatin. Background Art

[0002] Gelatin is a protein hydrolyzate extracted from animal connective tissue. Its main component is a polypeptide polymer formed by partial hydrolysis of collagen. It has unique gelling, film-forming, emulsifying and water-soluble properties, and is widely used in food, medicine, cosmetics, industry and other fields. Gelatin cannot be processed directly after production is completed, and it needs to go through sterilization and drying steps to ensure that it can meet food standards.

[0003] In the existing technology, high temperature is generally used to achieve sterilization and drying, which is more efficient and convenient during drying. However, under high temperature conditions, impurities inside the gelatin will undergo Maillard reaction and oxidation reaction with the gelatin molecules, thus generating dark substances, causing the solution color to deepen and the transparency to decrease. At the same time, under high temperature environment, the gelatin on the outside will solidify first, which will cause the evaporated water inside the gelatin to be unable to be discharged in time, which will further cause the transparency of the gelatin to decrease and affect the quality of the gelatin. Therefore, a sterilization and drying equipment for edible gelatin production is proposed to solve the above problems. Summary of the Invention

The high-pressure chamber and the negative-pressure chamber are connected to each other through a vacuum pump 6. The vacuum pump is a prior art and can start working when it is powered on. It can actively attract the surrounding air to flow and thus create a vacuum or high-pressure environment. The vacuum pump 6 suction port is connected to the negative-pressure chamber, and the vacuum pump 6 exhaust port is connected to the high-pressure chamber. When the vacuum pump 6 starts working, it can suck the gas inside the negative-pressure chamber into the high-pressure chamber, so that a negative pressure is formed inside the negative-pressure chamber and a high pressure is formed inside the high-pressure chamber. The outer wall of the ventilation pipe 5 is provided with a negative-pressure pipe 53 and a high-pressure pipe 52. The high-pressure pipe 52 is connected to the high-pressure chamber, and the negative-pressure pipe 53 is connected to the negative-pressure chamber.

[0022] Reference Figure 2-Figure 4 The drying box 3 is configured as a hollow rectangular box body, and the inner wall of the drying box 3 is configured as an inner box body 32. The interior of the inner box body 32 can be used to store gelatin to be processed. A cold air cavity 34 for accommodating cold air is provided between the inner box body 32 and the exhaust pipe 31. The inner box body 32 is provided with an exhaust pipe 31 for discharging the air inside the inner box body 32 near one end of the ventilation duct 5. A drying plate is installed on the inner wall of the exhaust pipe 31. The exhaust pipe 31 is communicated with the negative pressure pipe 53, and the exhaust pipe 31 can connect the negative pressure pipe 53 and the inner box body 32. A cold air pipe 33 for inputting gas into the cold air cavity 34 is provided at one end of the drying box 3 away from the ventilation duct 5. The cold air pipe 33 and the cold air cavity 34 are communicated with each other. A refrigerator 8 for generating cold air is installed on the outer wall of the cold air pipe 33. The cold air generated by the refrigerator 8 can enter the cold air cavity 34 through the cold air pipe 33: An ultraviolet lamp 21 for sterilization is installed on the inner wall of the sterilization box 2. The ultraviolet lamp 21 can be sterilized inside through transparent tape. A gas pipeline 22 for inputting gas is provided at one end of the sterilization box 2 close to the ventilation pipe 5. The gas pipeline 22 is connected to the high-pressure pipe 52. A vacuum pump 7 for replenishing the air pressure is installed on the outer wall of the high-pressure cavity of the ventilation pipe 5.

[0023] Reference Figure 4-Figure 6The regulating mechanism 9 includes a regulating pipe 2 92 and a regulating pipe 1 91. The regulating pipe 2 92 and the regulating pipe 1 91 can be used to guide the flow of gas. The regulating pipe 1 91 and the regulating pipe 2 92 are arranged on the inner wall of the ventilation pipe 5 from left to right. The direction of gas flow can be controlled by changing the positions of the regulating pipe 1 91 and the regulating pipe 2 92. The regulating pipe 2 92 and the regulating pipe 1 91 slide symmetrically on the inner wall of the ventilation pipe 5 with the center line of the partition plate 51 as the symmetry axis. The end of the regulating pipe 2 92 close to the vacuum pump 1 6 is provided with a connecting groove 97 for connecting to the vacuum pump 1 6. A connecting hole 99 for the negative pressure pipe 53 is provided at one end of the regulating pipe 2 92 close to the drying box 3, and a sealing plate 94 for closing the openings at both ends of the ventilation pipe 5 is fixedly connected to the end of the regulating pipe 2 92 away from the partition plate 51, and a balancing air hole 93 for balancing the pressure is provided on the outer wall of the regulating pipe 2 92 close to the sealing plate 94. When the regulating pipe 2 92 moves outward, the balancing air hole 93 will be separated from the interior of the ventilation pipe 5, so that the drying box 3 can be connected to the external environment, so that air can enter the interior of the drying box 3 through the balancing air hole 93, and the air pressure inside the drying box 3 can be restored.

[0024] Reference Figure 4-Figure 6 , a pressure gauge 95 for measuring the internal air pressure of the pipeline is installed on the outer wall of the ventilation pipeline 5, and the measuring port of the pressure gauge 95 passes through the outer wall of the ventilation pipeline 5, and a slide groove 96 for accommodating the pressure gauge 95 is provided on the upper surface of the regulating pipeline 2 92. The regulating pipeline 1 91 and the regulating pipeline 2 92 are the same components with the same appearance, and the regulating pipeline 1 91 and the regulating pipeline 2 92 are made of the same material and have the same physical properties. The difference between the regulating pipeline 1 91 and the regulating pipeline 2 92 is that the number of connecting grooves 97 on the front surface of the regulating pipeline 1 91 is two groups, one group of connecting grooves 97 corresponds to the exhaust port of the vacuum pump 1 6, and the other group of connecting grooves 97 corresponds to the exhaust port of the vacuum pump 2 7. When the regulating pipeline 1 91 moves outward, the two groups of connecting grooves 97 will be misaligned with the exhaust ports of the vacuum pump 1 6 and the vacuum pump 2 7 respectively. In this way, the vacuum pump 1 6 and the vacuum pump 2 7 will no longer be able to blow gas into the regulating pipeline 1 91.

[0025] Reference Figure 5-Figure 7The lower surface of the blocking plate 94 is provided with a driving assembly 98 for driving the blocking plate 94 to move. The driving assembly 98 includes a slider 984. The slider 984 is fixedly connected to the outer wall of the blocking plate 94. When the slider 984 moves, the blocking plate 94 will also be driven to move synchronously. The slider 984 slides on the inner wall of the support base 1. The slider 984 can slide left and right along the inner wall of the support base 1. The inner wall of the support base 1 is equipped with a double-headed motor 981. The internal output shaft of the double-headed motor 981 runs through the entire casing and can drive two The group device works, the double-headed motor 981 is a servo motor, and its number of rotations and rotation direction can be controlled. The outer wall of the output shaft of the double-headed motor 981 is provided with an external thread 982, and the output shaft of the double-headed motor 981 is threadedly connected to the slider 984 through the external thread 982. When the output shaft of the double-headed motor 981 rotates, the slider 984 can be driven to move left and right through the external thread 982. A cover plate 983 for shielding the double-headed motor 981 is installed on the upper surface of the support base 1 near the top of the double-headed motor 981.

[0026] Working principle: When the entire device is working, after the vacuum pump 6 is started, it will suck the air in the drying box 3 through the negative pressure cavity of the ventilation pipe 5, and pump it into the high-pressure cavity on one side of the sterilization box 2 through the exhaust port of the vacuum pump 6, and inject high-pressure gas into the sterilization box 2 through the high-pressure pipe 52 and the gas pipe 22, so that a high-pressure environment is formed in the sterilization box 2. At the same time, the ultraviolet lamp 21 on the inner wall of the sterilization box 2 emits UV-C band ultraviolet rays to destroy the DNA structure of microorganisms and achieve a double sterilization effect. The regulating pipe 91 in the regulating mechanism 9 is connected to the vacuum pump 6 and the vacuum pump 2 7 through the connecting groove 97. The air pressure can be supplemented by the vacuum pump 2 7 to maintain the pressure in the sterilization box 2 stable.

[0027] At this time, the refrigerator 8 delivers cold air to the cold air cavity 34 through the cold air pipe 33, lowering the temperature of the inner box 32 to a low temperature state. Under negative pressure and low temperature conditions, the moisture in the gelatin, especially the free water, directly sublimates from solid ice to water vapor, avoiding molecular aggregation caused by evaporation of liquid water. At the same time, the water vapor in the inner box 32 is sucked out through the exhaust pipe 31, which can prevent the water vapor from staying inside the inner box 32 for too long.

[0028] When the drying and sterilization operations are completed, the double-headed motor 981 can be started, and its output shaft is threadedly connected to the slider 984 through the external thread 982. When the motor is started, it can drive the slider 984 to slide outward along the inner wall of the support seat 1, and then push the sealing plate 94 and the regulating pipe 1 91 and the regulating pipe 2 92 to move outward synchronously. When the regulating pipe 1 91 and the regulating pipe 2 92 are away from the partition plate 51, the gas circulation is disconnected, and the sterilization box 2 and the drying box 3 can be connected to the outside world through the balance air hole 93, so that the operator can conveniently take the gelatin inside.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
