Description

Technical Field

[0001] This invention relates to a sterilization apparatus and method, and more particularly to a sterilization apparatus and method for gelatin production, belonging to the field of gelatin production technology. Background Technology

[0002] Gelatin is mainly derived from animal collagen through partial hydrolysis. It is a denatured product of collagen and belongs to the category of protein macromolecules. Its molecular structure consists of three polypeptide chains intertwined to form a helix. Through processing, the collagen molecular helix is ​​denatured and decomposed into α-components of single polypeptide chains (α-chains), β-components composed of two α-chains, γ-components composed of three α-chains, and molecular chain fragments in between and smaller or larger than α-components. The production process of gelatin mainly includes raw material pretreatment, hot water extraction, filtration, evaporation and concentration, gel formation and drying. To ensure the quality of gelatin, it is necessary to sterilize it during the production process.

[0003] Therefore, gelatin needs to be sterilized during the production process. However, at high temperatures, especially above 120°C, the three-dimensional structure of gelatin molecules changes, causing gelatin to lose 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 equipment cannot achieve the purpose of high-temperature instantaneous sterilization, thus leading to gelatin deterioration and performance decline.

[0004] Chinese invention patent publication number CN214015827U discloses "a sterilization and disinfection device suitable for gelatin production". It uses an electric heater to heat the heating coil inside the heating plate to achieve high-temperature sterilization and disinfection while protecting the gelatin from contamination. Then, the rotating shaft at the output end of the first motor drives the stirring blade to rotate, so that the gelatin particles are in full contact with the heating plate to achieve uniform heating of the gelatin particles and thoroughly sterilize the gelatin. However, it cannot control the heating time. Although it achieves the purpose of sterilization, it will seriously reduce the quality of the gelatin.

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

[0006] The purpose of this invention is to provide a sterilization device and method for gelatin production. After a certain temperature is reached inside the concentration sterilization chamber, the piston head discharges hot air into the gelatin liquid through the exhaust port, while simultaneously carrying away water vapor inside the gelatin solution, thus accelerating the concentration of the gelatin solution. The hot air is cooled by a cooling sterilization mechanism to prevent the heat from remaining for a long time. Therefore, the quality and performance of gelatin can be greatly improved, and the efficiency of concentration and cooling can also be improved.

[0007] To achieve the above objectives, the main technical solutions adopted by the present invention include: A sterilization device for gelatin production includes a rotating cylinder rotatably disposed inside a concentration sterilization chamber.

A metal plate is connected to a metal rod, and the metal plate abuts against the bottom of the carbon dioxide gasbag. Under the action of gravity, the heating strip support rod slides into the interior of the ventilation and stirring cylinder through the heating strip slide. After the temperature inside the ventilation and stirring cylinder rises, the carbon dioxide gasbag expands and pushes the heating strip out of the ventilation and stirring cylinder, which can heat the interior of the ventilation and stirring cylinder in real time.

The exhaust box is connected to the interior of the rotating cylinder through the exhaust pipe. When the fan is started, a negative pressure is formed inside the exhaust box. The hot air inside the concentration sterilization chamber enters the interior of the cooling and sterilization mechanism through the air inlet pipe. Under the action of the Norfolk solution, the Norfolk solution is carried into the interior of the concentration sterilization chamber, and the environment inside the concentration sterilization chamber is sterilized.

[0009] Preferably, one side of the concentration sterilization chamber is provided with a radiation instrument chamber corresponding to the aeration stirring cylinder. An organic transparent glass is fixedly installed inside the radiation instrument chamber, and a gamma ray meter is fixedly installed inside the radiation instrument chamber, with the gamma ray meter abutting against the organic transparent glass.

[0010] Preferably, the metal sheet is fixedly disposed at the bottom of the airbag braking chamber and abuts against the bottom of the carbon dioxide airbag, and the upper end of the carbon dioxide airbag abuts against the heating support frame; When the carbon dioxide gasbag expands due to heat, it pushes the heating support frame upwards. The heating strip is pushed away from the interior of the ventilated stirring cylinder. When the interior of the ventilated stirring cylinder is heated again, the carbon dioxide gas inside the carbon dioxide gasbag expands and generates an upward force, the calculation formula of which is: By P V = n R K; P = ; Where P is pressure, V is volume, n is amount of substance, R is ideal gas constant, and K is absolute temperature; The formula for converting absolute temperature to degrees Celsius is: t = K - 273.15; Where t is the temperature in Celsius.

[0012] Preferably, the rotating cylinder has several evenly distributed ventilation holes on its side, and the rotating cylinder is connected to the interior of the concentration sterilization chamber through the ventilation holes. A dustproof net is fixedly installed on the ventilation holes.

[0013] Preferably, the upper port of the rotating cylinder is connected to a drive disk, and the drive disk is rotatably connected to the concentration sterilization chamber via a bearing; The drive disk is provided with a driven gear, and the upper side of the concentration sterilization box is fixedly provided with a drive mechanism. The drive mechanism includes a drive motor, and the output end of the drive motor is provided with a drive gear. The drive gear meshes with the driven gear. The drive motor is used to rotate the drive disk. The drive motor is fixedly provided on the upper side of the concentration sterilization box through a motor fixing plate.

[0014] Preferably, the piston electric telescopic rod is fixedly mounted on the upper side of the concentration sterilization box via a telescopic rod bracket.

[0015] Preferably, a viewing window is provided on the side of the concentration sterilization chamber, the viewing window is connected to the interior of the concentration sterilization chamber, and an organic viewing window is fixedly provided inside the viewing window.

[0016] A method for using a sterilization device in a gelatin production process includes the following steps: Step 1: Gelatin liquid injection. The gelatin liquid to be concentrated is injected into the inside of the concentration and sterilization chamber through the feeding port. Step 2: Heating and stirring. After the gelatin liquid enters the interior of the concentration sterilization chamber, start the drive motor on the concentration sterilization chamber to drive the rotating drum to rotate through the drive gear, and at the same time drive the aerated stirring drum inside the rotating drum to rotate. Step 3: Sterilization, which includes: High-temperature instantaneous sterilization: The heating strip on the heating mechanism enters the interior of the ventilated mixing drum and heats the air inside the drum. After heating to 121°C, the piston electric telescopic rod is activated to pressurize the hot air through the piston head. The pressurized hot air is then discharged into the gelatin liquid through the exhaust nozzle on the mixing rod for sterilization. Chemical sterilization involves drawing air from the concentrated sterilization chamber through a fan inside the exhaust box and introducing it into the cooling sterilization mechanism. This air carries the Norfolk solution into the concentrated sterilization chamber for sterilization. Radiation sterilization involves activating a gamma ray device on one side of the concentration sterilization chamber to sterilize the gelatin solution while the rotating drum is spinning. Step 4: Heating and Concentration. During the stirring process, the air inside the concentration and sterilization chamber is heated by the heating strips on the heating mechanism to accelerate the concentration. Step 5: Gelation. After concentration and evaporation, the concentration sterilization chamber is cooled down by a cooling sterilization mechanism to achieve the purpose of cooling and solidification.

[0017] The present invention has at least the following beneficial effects: 1. After concentration, gelatin solution is often sterilized by a high-temperature sterilization device at 140°C for 4 seconds. The sterilization time is relatively short. After reaching a certain temperature inside the concentration sterilization chamber, heated air is discharged into the gelatin liquid through the piston head, stirring rod, and exhaust nozzle. Therefore, the gelatin liquid can be heated while being stirred. At the same time, by discharging heat into the gelatin liquid, the contact area between the heat and the gelatin liquid is increased. This method can effectively kill most bacteria and microorganisms in the gelatin and improve the sterilization efficiency.

[0018] 2. When the temperature inside the aerated mixing drum decreases, the heating mechanism, under the action of gravity, drives the heating strip into the interior of the aerated mixing drum and heats the air inside. When the temperature reaches a certain level, the metal block at the bottom of the piston head transfers heat to the metal plate through the metal rod, causing the carbon dioxide bladder to expand. After the carbon dioxide bladder expands, it drives the heating strip away from the interior of the aerated mixing drum to prevent the temperature from being too high and affecting the quality of the gelatin. During sterilization, the piston head compresses the air inside the aerated mixing drum and squeezes it into the gelatin solution through the exhaust nozzle to sterilize the gelatin solution. At the same time, it can also remove the water vapor inside the gelatin solution and accelerate the concentration of the gelatin solution.

[0019] 3. By activating the fan inside the exhaust box, a negative pressure is created inside the cooling and sterilization mechanism. Air from inside the concentration sterilization chamber is drawn into the cooling and sterilization mechanism through the air inlet pipe. After the hot air enters the condenser through the air inlet pipe and is cooled, it enters the Norfolk solution to sterilize the air. Then, it is discharged back into the concentration sterilization chamber by the fan. The purified air, carrying the Norfolk solution, sterilizes the air inside the concentration sterilization chamber. In addition, the low temperature of the air entering through the fan can also effectively reduce the temperature inside the concentration sterilization chamber.

[0020] 4. The gamma rays emitted by the gamma ray instrument penetrate into the interior of the concentration sterilization chamber through the organic transparent glass. While the gelatin solution is being stirred in the aerated stirring drum, the gamma ray instrument on one side of the concentration sterilization chamber simultaneously sterilizes the gelatin solution. The structure is simple and greatly improves the sterilization efficiency. Attached Figure Description

[0023] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0024] Examples, such as Figures 1-9 As shown, the sterilization device in the gelatin production process includes a rotating cylinder 2 rotatably disposed inside a concentration sterilization chamber 1. An aerated stirring cylinder 3 is slidably disposed inside the rotating cylinder 2. Since the rotating cylinder 2 rotates inside the concentration sterilization chamber 1 and the aerated stirring cylinder 3 slides inside the rotating cylinder 2, the rotation of the rotating cylinder 2 drives the aerated stirring cylinder 3 to rotate. The rotation of the aerated stirring cylinder 3 agitates the gelatin liquid inside the concentration sterilization chamber 1. A braking mechanism 4 is provided at the upper end of the aerated stirring cylinder 3. The braking mechanism 4 includes a piston electric telescopic rod 401 and a piston head 402 connected via a telescopic rod output shaft 404. The piston head 402 slides inside the aerated stirring cylinder 3. Several... A uniformly distributed stirring rod 302 is connected to an exhaust nozzle 303. The exhaust nozzle 303 is connected to the interior of the ventilated stirring cylinder 3 through the stirring rod 302. After the gelatin solution is concentrated, it is usually sterilized by a high-temperature sterilization device at 140°C for 4 seconds. The sterilization time is relatively short. After a certain temperature is reached inside the concentration sterilization chamber 1, the heated air is discharged into the interior of the gelatin liquid through the piston head 402 via the stirring rod 302 and the exhaust nozzle 303. Therefore, the gelatin liquid can be heated while being stirred. At the same time, by discharging heat into the interior of the gelatin liquid, the contact area between the heat and the gelatin liquid is increased. This method can effectively kill most of the bacteria and microorganisms in the gelatin and improve the sterilization efficiency.

[0025] For high-temperature instantaneous sterilization, to achieve a high temperature of 140 degrees Celsius, a heating mechanism 7 is installed on the piston head 402. An airbag braking chamber 405 is opened on the telescopic rod output shaft 404. The heating mechanism 7 is slidably installed 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 located inside the airbag braking chamber 405. Several evenly distributed heating strip support rods 703 are installed on the heating support frame 701. Heating strips 704 are fixedly installed at the bottom of the heating strip support rods 703. Several evenly distributed heating strip sliding chambers 403 are opened on the piston head 402. The heating strip support rods 703 are slidably installed inside the heating strip sliding chambers 403. In the piston head 402, a metal block 705 is fixedly installed at the bottom. The metal block 705 is connected to a metal plate 707 via a metal rod 706. The metal plate 707 abuts against the bottom of the carbon dioxide gas bag 702. Under the action of gravity, the heating strip support rod 703 slides into the interior of the ventilation and stirring cylinder 3 through the heating strip slide 403. When the temperature inside the ventilation and stirring cylinder 3 rises, the carbon dioxide gas bag 702 expands and pushes the heating strip 704 out of the ventilation and stirring cylinder 3, which can heat the interior of the ventilation and stirring cylinder 3 in real time. The piston head 402 is moved downward by the braking mechanism 4, and the hot air inside the ventilation and stirring cylinder 3 is quickly discharged into the interior of the concentration sterilization chamber 1 through the exhaust port 303 to achieve the purpose of sterilization.

[0026] In other words, when the temperature inside the ventilated mixing cylinder 3 decreases, the heating mechanism 7, under the action of gravity, drives the heating strip 704 into the interior of the ventilated mixing cylinder 3 and heats the air inside the ventilated mixing 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 plate 707 through the metal rod 706, causing the carbon dioxide gasbag 702 to expand. After the carbon dioxide gasbag 702 expands, it drives the heating strip 704 to push away from the interior of the ventilated mixing cylinder 3, preventing the temperature from being too high and affecting the quality of the gelatin.

[0027] Then, the piston electric telescopic rod 401 on the starting braking mechanism 4 drives the piston head 402 to compress the air inside the ventilated stirring cylinder 3, and squeezes it into the gelatin solution through the exhaust nozzle 303 to sterilize the gelatin solution. At the same time, it can also remove the water vapor inside the gelatin solution and accelerate the concentration of the gelatin solution.

[0028] Chemical sterilization, even the interior of the concentrated sterilization chamber 1 may contain bacteria, such as... Figure 4As shown, a cooling sterilization mechanism 6 is fixedly installed on one side of the concentration sterilization chamber 1. The interior of the cooling sterilization mechanism 6 is filled with Norfolk solution 603. The upper end of the cooling sterilization mechanism 6 is connected to the interior of the concentration sterilization chamber 1 through an air inlet pipe 601. A condenser pipe 602 is connected to the bottom of the air inlet pipe 601. The condenser pipe 602 is immersed in the Norfolk solution 603. A fan 606 is fixedly installed inside the exhaust box 604. An exhaust pipe 605 is connected to the upper side of the exhaust box 604 and extends to... Inside the rotating cylinder 2, the exhaust box 604 is connected to the interior of the rotating cylinder 2 via the exhaust pipe 605. After the fan 606 is started, a negative pressure is formed inside the exhaust box 604, and the hot air inside the concentration sterilization chamber 1 enters the interior of the cooling sterilization mechanism 6 through the air inlet pipe 601. Under the action of the Norfolk solution 603, the Norfolk solution 603 vapor is carried into the interior of the concentration sterilization chamber 1, and sterilizes the environment inside the concentration sterilization chamber 1. By starting the fan 606 inside the exhaust box 604, ... A negative pressure is created inside the cooling sterilization mechanism 6. Air from inside the concentration sterilization chamber 1 is drawn into the cooling sterilization mechanism 6 through the air inlet pipe 601. After the hot air enters the condenser pipe 602 through the air inlet pipe 601 and is cooled, it enters the Norfolk solution 603 to sterilize the air. Then, it is discharged back into the concentration sterilization chamber 1 through the fan 606. The purified air carries the Norfolk solution 603 solution to sterilize the air inside the concentration sterilization chamber 1. In addition, the low temperature of the air entering through the fan 606 can effectively reduce the temperature inside the concentration sterilization chamber 1. Several evenly distributed vent holes 203 are opened on the side of the rotating cylinder 2. The rotating cylinder 2 is connected to the inside of the concentration sterilization chamber 1 through the vent holes 203. A dustproof net 205 is fixedly installed on the vent holes 203. The sterilized gas enters the inside of the rotating cylinder 2 through the fan 606 and enters the inside of the concentration sterilization chamber 1 through the vent holes 203 on the rotating cylinder 2, which accelerates the cooling of the gelatin solution and improves the processing efficiency.

[0029] On one side of the air inlet pipe 601, an exhaust box 604 connected to the cooling and sterilization mechanism 6 is provided. On one side of the exhaust box 604, a feeding valve 607 is provided. Since the liquefaction of water vapor will reduce the concentration of Norfolk solution 603, the concentration of Norfolk solution 603 can be adjusted through the feeding valve 607, which improves the convenience of use and speeds up the concentration of gelatin solution. Hot air is cooled by the cooling and sterilization mechanism 6 to prevent heat from staying for a long time. Therefore, the quality and performance of gelatin can be greatly improved, and the efficiency of concentration and cooling can also be improved.

[0030] Radiation sterilization, such as Figure 9As shown, a radiation chamber 102 corresponding to the aeration stirring cylinder 3 is provided on one side of the concentration sterilization chamber 1. An organic transparent glass 103 is fixedly installed inside the radiation chamber 102, and a gamma ray meter 8 is fixedly installed inside the radiation chamber 102. The gamma ray meter 8 is against the organic transparent glass 103, and the gamma rays emitted by the gamma ray meter 8 pass through the organic transparent glass 103 and enter the interior of the concentration sterilization chamber 1. When the aeration stirring cylinder 3 stirs the gelatin solution, the gamma ray meter 8 on one side of the concentration sterilization chamber 1 simultaneously sterilizes the gelatin solution. The structure is simple and greatly improves the sterilization efficiency.

[0031] Furthermore, such as Figure 1 and Figure 7 As shown, the metal sheet 707 is fixedly installed 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, heat is transferred from the metal block 705 to the metal rod 706 through heat conduction and then to the carbon dioxide airbag 702 through the metal sheet 707. Therefore, the carbon dioxide airbag 702 expands. After the carbon dioxide airbag 702 expands, it squeezes the heating support frame 701 and squeezes the heating strip 704 out of the ventilation stirring cylinder 3, thus stopping the heating of the inside of the ventilation stirring cylinder 3.

[0032] When the carbon dioxide gasbag 702 expands due to heat, it pushes the heating support frame 701 upwards. The heating strip 704 is pushed away from the interior of the ventilated stirring cylinder 3. When the interior of the ventilated stirring cylinder 3 is heated again, the carbon dioxide gas inside the carbon dioxide gasbag 702 expands and generates an upward force. The calculation formula is as follows: By P V = n R K; P = ; Where P is pressure, V is volume, n is amount of substance, R is ideal gas constant, and K is absolute temperature; The formula for converting absolute temperature to degrees Celsius is: t = K - 273.15; Where t is the temperature in Celsius, the volume of the carbon dioxide airbag 702 is calculated and the required heating temperature is confirmed, then the overall mass of the heating mechanism 7 is adjusted, and the heating mechanism 7 can be driven to move upward by the expansion of the carbon dioxide airbag 702 without manual adjustment, avoiding excessive temperature and improving ease of use.

[0033] Furthermore, such as Figure 1 and Figure 6As shown, the bottom of the rotating cylinder 2 is provided with a stirring cylinder groove 204, and the ventilated stirring cylinder 3 is slidably disposed inside the stirring cylinder groove 204. The upper end of the ventilated stirring cylinder 3 is provided with symmetrically distributed telescopic rod fixing blocks 304, and the bottom of the telescopic rod fixing blocks 304 is provided with a stirring cylinder electric telescopic rod 301. The stirring cylinder electric telescopic rod 301 is fixedly disposed inside the rotating cylinder 2. The stirring cylinder electric telescopic rod 301 is used to vertically push the ventilated stirring cylinder 3. The ventilated stirring cylinder 3 and the rotating cylinder 2 are fixed together by 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 for removing the cured gelatin later. The structure is simple and improves the convenience of use.

[0034] A drive disc 201 is connected to the upper end of the rotating cylinder 2. The drive disc 201 is rotatably connected to the concentration sterilization chamber 1 via bearings. A driven gear 202 is provided on the drive disc 201. A drive mechanism 5 is fixedly installed on the upper side of the concentration sterilization chamber 1. The drive mechanism 5 includes a drive motor 502. A drive gear 503 is provided at the output end of the drive motor 502. The drive gear 503 meshes with the driven gear 202. The drive motor 502 is used to rotate the drive disc 201. The drive motor 502 is fixedly installed on the upper side of the chamber 1 via a motor mounting plate 501. On the upper side of the concentration sterilization chamber 1, the drive motor 502 is fixedly mounted on the concentration sterilization chamber 1 via the motor fixing plate 501. After starting the drive motor 502, the drive gear 503 drives the drive disk 201 on the rotating drum 2 to rotate. Thus, the rotating drum 2 can rotate inside the concentration sterilization chamber 1. The rotation of the ventilated stirring drum 3 horizontally stirs the gelatin inside the concentration sterilization chamber 1. The electric telescopic rod 301 of the stirring drum enables the ventilated stirring drum 3 to vertically stir the gelatin solution, improving the uniformity of stirring.

[0035] Furthermore, such as Figure 1 , Figure 2 as well as Figure 9 As shown, the piston electric telescopic rod 401 is fixedly mounted on the upper side of the concentration sterilization chamber 1 via the telescopic rod bracket 407. The upper side of the concentration sterilization chamber 1 has a feeding port 101 connected to the concentration sterilization chamber 1. The bottom side of the concentration sterilization chamber 1 has a discharge port 104 connected to the interior of the concentration sterilization chamber 1. The bottom of the concentration sterilization chamber 1 is provided with symmetrically distributed support feet 105, which support the concentration sterilization chamber 1 and improve its stability. A viewing window 106 is provided on the side of the concentration sterilization chamber 1, which is connected to the interior of the concentration sterilization chamber 1. An organic viewing window 9 is fixedly installed inside the viewing window 106, allowing direct observation of the interior of the concentration sterilization chamber 1 through the organic viewing window 9 inside the viewing window 106, improving timeliness, facilitating observation, and enhancing ease of use.

[0036] like Figures 1-9 As shown, the method of using the sterilization device in the gelatin production process provided in this embodiment includes the following steps: Step 1: Gelatin liquid injection. The gelatin liquid to be concentrated is injected into the inside of the concentration sterilization chamber 1 through the feeding port 101. Step 2: Heating and stirring. After the gelatin liquid enters the interior of the concentration sterilization chamber 1, the drive motor 502 on the concentration sterilization chamber 1 is started, which drives the rotating drum 2 to rotate through the drive gear 503. At the same time, the aerated stirring drum 3 inside the rotating drum 2 is also rotated. Step 3: Sterilization, which includes: High-temperature instantaneous sterilization: The heating bar 704 on the heating mechanism 7 enters the interior of the ventilated stirring cylinder 3 and heats the air inside the ventilated stirring cylinder 3. After heating to 121°C, the piston electric telescopic rod 401 is activated to pressurize the hot air through the piston head 402. The pressurized hot air is discharged into the gelatin liquid through the exhaust nozzle 303 on the stirring rod 302 for sterilization. Chemical sterilization involves drawing air from the concentrated sterilization chamber 1 through the fan 606 inside the exhaust box 604 and introducing it into the cooling sterilization mechanism 6, carrying the Norfolk solution 603 into the concentrated sterilization chamber 1 for sterilization. Radiation sterilization: During the rotation of the rotating drum 2, the gamma ray instrument 8 on one side of the concentration sterilization chamber 1 is activated to sterilize the gelatin solution. Step 4: Heating and Concentration. During the stirring process, the air inside the concentration and sterilization chamber 1 is heated by the heating strip 704 on the heating mechanism 7 to accelerate the concentration. Step 5: After gelation and concentration evaporation, the concentration sterilization chamber 1 is cooled down by the cooling sterilization mechanism 6 to achieve the purpose of cooling and solidification.
