Description

Technical Field

[0001] The present invention relates to a sterilization device and method, in particular to a sterilization device and method in the process of gelatin production, belonging to the technical field of gelatin production. Background Art

[0002] Gelatin is mainly derived from the partial hydrolysis of animal collagen. It is a denatured product of collagen and belongs to the category of protein macromolecules. Its molecular structure is formed by three polypeptide chains winding around each other to form a helix. Through process treatment, the collagen molecular helix denatures and decomposes into the α-component of a single polypeptide chain (α-chain), the β-component composed of two α-chains, the γ-component composed of three α-chains, and molecular chain fragments between them and smaller than the α-component or larger than the γ-component. The production process of gelatin mainly includes steps such as raw material pretreatment, hot water extraction, filtration, evaporation concentration, gel forming, and drying. In order to ensure the quality of gelatin, it is necessary to sterilize gelatin during the production process.

[0003] Therefore, it is necessary to sterilize gelatin during the production process. However, at high temperatures, especially when exceeding 120 °C, the three-dimensional structure of its molecules will change, resulting in gelatin losing its original gelling ability. This change makes it impossible for gelatin to form a stable gel structure in subsequent processing and applications, thus affecting the quality and performance of the product. Existing devices cannot achieve the purpose of high-temperature instantaneous sterilization, resulting in the deterioration of gelatin and the decline of its performance.

[0004] Chinese Invention Patent Publication No. CN214015827U discloses "a sterilization and disinfection device suitable for gelatin production". The heating coil inside the heating plate is heated by an electric heater to achieve the purpose of high-temperature sterilization and disinfection, and to protect gelatin from contamination. Then, the stirring blade is driven to rotate by the rotating shaft at the output end of the first motor, so that the gelatin particles are in full contact with the heating plate, in order to achieve the purpose of uniform heating of the gelatin particles, thereby thoroughly sterilizing and disinfecting the gelatin, but the heating time cannot be controlled. Although the purpose of sterilization is achieved, the quality of gelatin will be seriously reduced.

[0005] Therefore, it is urgent to improve the sterilization device in the process of gelatin production to solve the above problems. Summary of the Invention

[0006] The purpose of the present invention is to provide a sterilization device and method in the process of gelatin production. After reaching a certain temperature inside the concentration sterilization box, the piston head discharges hot air into the gelatin liquid through the exhaust nozzle, and at the same time takes away the water vapor inside the gelatin solution, accelerating the concentration of the gelatin solution. The hot air is cooled by the cooling sterilization mechanism to prevent the long-term retention of heat. Therefore, the quality and performance of gelatin can be greatly improved, and at the same time, the concentration and cooling efficiency can also be improved.

[0026] Preferably, a perspective window is provided on the side surface of the concentration sterilization box, the perspective window is communicated with the inside of the concentration sterilization box, and an organic visual window is fixedly arranged inside the perspective window.

[0027] A using method of a sterilization device in the production process of gelatin includes the following steps:

[0028] Step 1: Injecting gelatin liquid, injecting the gelatin liquid to be concentrated into the inside of the concentration sterilization box through the feeding port;

[0029] Step 2: Heating and stirring, after the gelatin liquid enters the inside of the concentration sterilization box, start the driving motor on the concentration sterilization box to drive the rotating cylinder to rotate through the driving gear, and at the same time drive the ventilation stirring cylinder inside the rotating cylinder to rotate;

[0030] Step 3: Sterilization, the sterilization includes:

[0031] High-temperature instantaneous sterilization: The heating bars on the heating mechanism enter the inside of the ventilation and stirring cylinder, and heat the air inside the ventilation and stirring cylinder. After heating to 121 °C, the piston electric telescopic rod is started to pressurize the hot air through the piston head. The pressurized hot air is discharged into the inside of the gelatin liquid through the exhaust nozzles on the stirring rod for sterilization.

[0032] Chemical sterilization: The air inside the concentrated sterilization box is extracted by the fan inside the exhaust box and enters the inside of the cooling and sterilization mechanism, carrying the Noflox solution into the inside of the concentrated sterilization box for sterilization.

[0033] Radiation sterilization: During the rotation of the rotating cylinder, the γ-ray instrument on one side of the concentrated sterilization box is started to sterilize the gelatin solution.

[0034] Step 4: Heating and concentration: During stirring, the air inside the concentrated sterilization box is heated by the heating bars on the heating mechanism to accelerate concentration.

[0035] Step 5: Gelatinization: After concentration and evaporation, the concentrated sterilization box is cooled by the cooling and sterilization mechanism to achieve the purpose of cooling and solidification.

[0036] The present invention has at least the following beneficial effects:

[0037] 1. After the gelatin solution is concentrated, it is often sterilized by a high-temperature 140 °C instantaneous sterilization device for 4 seconds. The sterilization time is short. After reaching a certain temperature inside the concentrated sterilization box, the heated air is discharged into the inside of the gelatin liquid through the piston head, the stirring rod and the exhaust nozzles. Therefore, it is possible to heat the gelatin liquid while stirring, and at the same time, by discharging the heat into the inside of the gelatin liquid, the contact area with the gelatin liquid is increased. This method can effectively kill most bacteria and microorganisms in the gelatin and improve the sterilization efficiency.

[0038] 2. When the temperature inside the ventilation and stirring cylinder decreases, the heating mechanism drives the heating bars to slide into the inside of the ventilation and stirring cylinder under the action of gravity and heats the air inside the ventilation and stirring cylinder. When the temperature reaches a certain level, the metal block at the bottom of the piston head transfers the heat to the metal sheet through the metal rod, causing the carbon dioxide airbag to expand. After the carbon dioxide airbag expands, it drives the heating bars to push out of the inside of the ventilation and stirring cylinder to prevent the temperature from being too high and affecting the quality of the gelatin. During sterilization, the piston head squeezes the air inside the ventilation and stirring cylinder and discharges it into the inside of the gelatin solution through the exhaust nozzles to sterilize the gelatin solution, and at the same time, it can also carry away the water vapor inside the gelatin solution and accelerate the concentration of the gelatin solution.

[0039] 3. By starting the fan inside the air extraction box, a negative pressure is formed inside the cooling and sterilization mechanism. The air inside the concentration sterilization box is drawn into the inside of the cooling and sterilization mechanism through the intake pipe. After the hot air enters the inside of the condensing pipe through the intake pipe, it is cooled and then enters the inside of the Novus solution to sterilize the air. Then, it is discharged back into the concentration sterilization box through the fan again. The purified air carrying the Novus solution sterilizes the air inside the concentration sterilization box. In addition, the low temperature of the air entering through the fan can effectively reduce the temperature inside the concentration sterilization box.

[0040] 4. The γ-rays emitted by the γ-ray instrument penetrate into the inside of the concentration sterilization box through the organic perspective glass. When the ventilation and stirring cylinder stirs the gelatin solution, the γ-ray instrument on one side of the concentration sterilization box sterilizes the gelatin solution at the same time. The structure is simple and the sterilization efficiency is greatly improved. Brief Description of the Drawings

Detailed implementation manners

[0052] The following will describe in detail the implementation manners of the present application in conjunction with the accompanying drawings and embodiments, so as to fully understand how the present application uses technical means to solve technical problems and achieve the implementation process of technical effects and implement accordingly.

[0053] Embodiment, as Figures 1-9As shown in the figure, the sterilization device in the gelatin production process includes a rotating cylinder 2 rotatably arranged inside a concentration sterilization tank 1. A ventilation stirring cylinder 3 is slidably arranged inside the rotating cylinder 2. The rotating cylinder 2 is rotatably arranged inside the concentration sterilization tank 1, and the ventilation stirring cylinder 3 is slidably arranged inside the rotating cylinder 2. Therefore, while the rotating cylinder 2 rotates, it can drive the ventilation stirring cylinder 3 to rotate. The rotation of the ventilation stirring cylinder 3 can stir the gelatin liquid inside the concentration sterilization tank 1. A braking mechanism 4 is arranged at the upper end of the ventilation stirring cylinder 3. The braking mechanism 4 includes a piston electric telescopic rod 401 and a piston head 402 connected through a telescopic rod output shaft 404. The piston head 402 is slidably arranged inside the ventilation stirring cylinder 3. A plurality of uniformly distributed stirring rods 302 are connected to the bottom of the ventilation stirring cylinder 3. An exhaust nozzle 303 is connected to the stirring rod 302. The exhaust nozzle 303 is communicated with the inside of the ventilation stirring cylinder 3 through the stirring rod 302. After the gelatin solution is concentrated, it is often sterilized by a high-temperature instantaneous sterilization device at 140°C for 4 seconds. The sterilization time is short. After reaching a certain temperature inside the concentration sterilization tank 1, the heated air is discharged into the gelatin liquid through the piston head 402, the stirring rod 302, and the exhaust nozzle 303. Therefore, it can achieve heating the gelatin liquid while stirring. At the same time, by discharging the heat into the gelatin liquid, the contact area with the gelatin liquid is increased. This method can effectively kill most bacteria and microorganisms in the gelatin and improve the sterilization efficiency.

[0054] For high-temperature instantaneous sterilization, in order to reach a high temperature of 140 degrees, a heating mechanism 7 is arranged on the piston head 402. An airbag braking chamber 405 is provided on the telescopic rod output shaft 404. The heating mechanism 7 is slidably arranged inside the airbag braking chamber 405. The heating mechanism 7 includes a heating support frame 701 and a carbon dioxide airbag 702. The carbon dioxide airbag 702 is arranged inside the airbag braking chamber 405. A plurality of uniformly distributed heating strip support rods 703 are arranged on the heating support frame 701. A heating strip 704 is fixedly arranged at the bottom of the heating strip support rod 703. A plurality of uniformly distributed heating strip sliding chambers 403 are provided on the piston head 402. The heating strip support rod 703 is slidably arranged inside the heating strip sliding chamber 403. A metal block 705 is fixedly arranged at the bottom of the piston head 402. The metal block 705 is connected to a metal sheet 707 through a metal rod 706. The metal sheet 707 abuts against the bottom of the carbon dioxide airbag 702. Under the action of gravity, the heating strip support rod 703 slides into the ventilation stirring cylinder 3 through the heating strip sliding chamber 403. After the temperature inside the ventilation stirring cylinder 3 rises, the carbon dioxide airbag 702 expands and pushes the heating strip 704 out of the ventilation stirring cylinder 3, which can heat the inside of the ventilation stirring cylinder 3 in real time. Through the braking mechanism 4, the piston head 402 moves downward, and the hot air inside the ventilation stirring cylinder 3 is quickly discharged into the concentration sterilization tank 1 through the exhaust nozzle 303 to achieve the purpose of sterilization.

[0055] That is to say, when the temperature inside the ventilation stirring cylinder 3 decreases, the heating mechanism 7 drives the heating strip 704 to slide into the inside of the ventilation stirring cylinder 3 under the action of gravity, and heats the air inside the ventilation stirring cylinder 3. When the temperature reaches a certain level, the metal block 705 at the bottom of the piston head 402 transfers the heat to the metal sheet 707 through the metal rod 706, causing the carbon dioxide airbag 702 to expand. After the carbon dioxide airbag 702 expands, it drives the heating strip 704 to push away from the inside of the ventilation stirring cylinder 3 to prevent the temperature from being too high and affecting the quality of the gelatin.

[0056] Then, the piston electric telescopic rod 401 on the braking mechanism 4 is started to drive the piston head 402 to squeeze the air inside the ventilation stirring cylinder 3 and squeeze it into the inside of the gelatin solution through the exhaust nozzle 303 to sterilize the gelatin solution. At the same time, it can also take away the water vapor inside the gelatin solution and accelerate the concentration of the gelatin solution.

[0057] For chemical sterilization, there may also be bacteria inside the concentration sterilization box 1, such as Figure 4As shown in the figure, a cooling and sterilization mechanism 6 is fixedly arranged on one side of the concentrated sterilization box 1. The inside of the cooling and sterilization mechanism 6 is filled with Nof solution 603. The upper end of the cooling and sterilization mechanism 6 is connected to the inside of the concentrated sterilization box 1 through an air inlet pipe 601. The bottom of the air inlet pipe 601 is connected with a condensing pipe 602, and the condensing pipe 602 is immersed in the Nof solution 603. A fan 606 is fixedly arranged inside the air extraction box 604. The upper side of the air extraction box 604 is connected with an exhaust pipe 605, and the exhaust pipe 605 extends into the inside of the rotating cylinder 2. The air extraction box 604 is connected to the inside of the rotating cylinder 2 through the exhaust pipe 605. After the fan 606 is started, a negative pressure is formed inside the air extraction box 604, and the hot air inside the concentrated sterilization box 1 enters the inside of the cooling and sterilization mechanism 6 through the air inlet pipe 601. Under the action of the Nof solution 603, it carries the Nof solution 603 steam into the inside of the concentrated sterilization box 1 and sterilizes the environment inside the concentrated sterilization box 1. By starting the fan 606 inside the air extraction box 604, a negative pressure is formed inside the cooling and sterilization mechanism 6, and the air inside the concentrated sterilization box 1 is drawn into the inside of the cooling and sterilization mechanism 6 through the air inlet pipe 601. After the hot air enters the inside of the condensing pipe 602 through the air inlet pipe 601, it is cooled and then enters the inside of the Nof solution 603 to sterilize the air, and then is discharged into the inside of the concentrated sterilization box 1 again through the fan 606. The purified air carrying the Nof solution 603 solution sterilizes the air inside the concentrated sterilization box 1. In addition, the air entering through the fan 606 has a low temperature and can effectively reduce the temperature inside the concentrated sterilization box 1. A number of uniformly distributed ventilation holes 203 are formed on the side of the rotating cylinder 2, and the rotating cylinder 2 is connected to the inside of the concentrated sterilization box 1 through the ventilation holes 203. A dust-proof net 205 is fixedly arranged on the ventilation holes 203. The sterilized gas enters the inside of the rotating cylinder 2 through the fan 606 and enters the inside of the concentrated sterilization box 1 through the ventilation holes 203 on the rotating cylinder 2, accelerating the cooling of the gelatin solution and improving the processing efficiency.

[0058] An air extraction box 604 connected to the cooling and sterilization mechanism 6 is arranged on one side of the air inlet pipe 601. A feeding valve 607 is arranged on one side of the air extraction box 604. Since the liquefaction of water vapor will cause the concentration of the Nof solution 603 to decrease, the concentration of the Nof solution 603 can be adjusted through the feeding valve 607, improving the convenience of use and accelerating the concentration of the gelatin solution. The hot air is cooled through the cooling and sterilization mechanism 6 to prevent the long-term retention of heat. Therefore, the quality and performance of the gelatin can be greatly improved, and at the same time, the concentration and cooling efficiency can also be improved.

[0059] Radiation sterilization, such as Figure 9As shown in the figure, a ray instrument chamber 102 corresponding to the ventilation stirring cylinder 3 is provided on one side of the concentrated sterilization box 1. An organic perspective glass 103 is fixedly arranged inside the ray instrument chamber 102. A γ-ray instrument 8 is fixedly arranged inside the ray instrument chamber 102. The γ-ray instrument 8 abuts against the organic perspective glass 103. The γ-rays emitted by the γ-ray instrument 8 penetrate into the inside of the concentrated sterilization box 1 through the organic perspective glass 103. When the ventilation stirring cylinder 3 stirs the gelatin solution, the γ-ray instrument 8 on one side of the concentrated sterilization box 1 sterilizes the gelatin solution at the same time. The structure is simple and the sterilization efficiency is greatly improved.

[0060] Further, as Figure 1 and Figure 7 shown, a metal sheet 707 is fixedly arranged at the bottom of the airbag braking chamber 405 and abuts against the bottom of the carbon dioxide airbag 702. The upper end of the carbon dioxide airbag 702 abuts against the heating support frame 701. After the temperature inside the ventilation stirring cylinder 3 rises, the heat is transferred from the metal block 705 to the metal rod 706 and then to the carbon dioxide airbag 702 through the metal sheet 707 by heat conduction. Therefore, the carbon dioxide airbag 702 expands. After the carbon dioxide airbag 702 expands, it squeezes the heating support frame 701, extrudes the heating strip 704 from the ventilation stirring cylinder 3, and stops heating the inside of the ventilation stirring cylinder 3.

[0061] After the carbon dioxide airbag 702 expands due to heat, it pushes the heating support frame 701 upward, and the heating strip 704 is pushed out of the inside of the ventilation stirring cylinder 3. When heating the inside of the ventilation stirring cylinder 3 again, the carbon dioxide gas inside the carbon dioxide airbag 702 expands and generates an upward force. Its calculation formula is:

[0062] From P V = n R K;

[0063] We get P = ;

[0064] Among them, P is pressure, V is volume, n is the amount of substance, R is the ideal gas constant, and K is the absolute temperature;

[0065] The conversion formula between absolute temperature and Celsius is:

[0066] t = K - 273.15;

[0067] Among them, t is the Celsius temperature. Calculate the volume of the carbon dioxide airbag 702 and confirm the temperature to be heated, then adjust the overall mass of the heating mechanism 7, and the expansion of the carbon dioxide airbag 702 can drive the heating mechanism 7 to move upward, without manual adjustment, avoiding too high temperature and improving the convenience of use.

[0068] Furthermore, as Figure 1 and Figure 6 shown, a stirring cylinder chute 204 is provided at the bottom of the rotating cylinder 2, and the ventilated stirring cylinder 3 is slidably arranged inside the stirring cylinder chute 204. Symmetrically distributed telescopic rod fixing blocks 304 are provided at the upper port of the ventilated stirring cylinder 3, and a stirring cylinder electric telescopic rod 301 is provided at the bottom of the telescopic rod fixing block 304. The stirring cylinder electric telescopic rod 301 is fixedly arranged inside the rotating cylinder 2. The stirring cylinder electric telescopic rod 301 is used to vertically push the ventilated stirring cylinder 3, and the ventilated stirring cylinder 3 is fixed to the rotating cylinder 2 through the stirring cylinder electric telescopic rod 301. Therefore, the vertical sliding of the ventilated stirring cylinder 3 inside the rotating cylinder 2 can be controlled, which is convenient for fully stirring the gelatin solution and convenient for later taking out the solidified gelatin. The structure is simple and the convenience of use is improved.

[0069] The upper port of the rotating cylinder 2 is connected with a driving disk 201. The driving disk 201 is rotationally connected with the concentration sterilization box 1 through a bearing. A driven gear 202 is arranged on the driving disk 201. A driving mechanism 5 is fixedly arranged on the upper side of the concentration sterilization box 1. The driving mechanism 5 includes a driving motor 502. A driving gear 503 is arranged at the output end of the driving motor 502. The driving gear 503 is meshed with the driven gear 202. The driving motor 502 is used to rotate the driving disk 201. The driving motor 502 is fixedly arranged on the upper side of the concentration sterilization box 1 through a motor fixing plate 501. After the driving motor 502 is fixedly arranged on the concentration sterilization box 1 through the motor fixing plate 501, the driving motor 502 is started to drive the rotation of the driving disk 201 on the rotating cylinder 2 through the driving gear 503. Therefore, the rotating cylinder 2 can be driven to rotate inside the concentration sterilization box 1. The gelatin inside the concentration sterilization box 1 is horizontally stirred through the rotation of the ventilated stirring cylinder 3, and the gelatin solution is vertically stirred by the ventilated stirring cylinder 3 through the stirring cylinder electric telescopic rod 301, improving the uniformity of stirring.

[0070] Still further, as Figure 1 、 Figure 2 and Figure 9As shown in the figure, the piston electric telescopic rod 401 is fixedly arranged on the upper side of the concentration sterilization box 1 through the telescopic rod bracket 407. A feeding port 101 communicating with the concentration sterilization box 1 is provided on the upper side of the concentration sterilization box 1. A discharging port 104 communicating with the inside of the concentration sterilization box 1 is provided on the bottom side of the concentration sterilization box 1. Symmetrically distributed supporting feet 105 are arranged at the bottom of the concentration sterilization box 1. The concentration sterilization box 1 is supported by the supporting feet 105 to improve the stability of the concentration sterilization box 1. A perspective window 106 is provided on the side of the concentration sterilization box 1. The perspective window 106 communicates with the inside of the concentration sterilization box 1. An organic visual window 9 is fixedly arranged inside the perspective window 106. The situation inside the concentration sterilization box 1 can be directly observed through the organic visual window 9 inside the perspective window 106, improving the timeliness, facilitating observation, and enhancing the convenience of use.
