Description

Technical Field

[0001] This utility model relates to the field of edible gelatin production technology, specifically to a sterilization device for edible gelatin production. Background Technology

[0002] Edible gelatin is a water-soluble protein extracted from animal collagen, such as pig skin, cow skin, fish skin or bones. It is widely used in the food, pharmaceutical and cosmetic industries. In the production process of edible gelatin, sterilization equipment is required to sterilize it.

[0003] The utility model with announcement number CN221410295U discloses a sterilization device for the production of edible gelatin, including a heating and drying box. A heating tank is provided on the left side wall of the heating and drying box, and a door is hinged to the side wall of the heating tank. A conveying trough is installed at the front end of the heating and drying box. A sterilization liquid tank is installed on the right side wall of the conveying trough. An inlet is connected to the front part of the upper end of the sterilization liquid tank. Two inlet pipes are provided at the rear end of the inlet. A spray plate is installed at the lower end of each inlet pipe, and three small pipes are connected to the lower end of each spray plate.

[0004] The above technical solution involves injecting sterilizing solution into the inlet, activating the pump, and then injecting the sterilizing solution into two infusion tubes. The solution then enters the spray plate and is sprayed onto the surface of the edible gelatin through a small tube for sterilization. Using two spray plates ensures even spraying of the sterilizing solution, achieving thorough sterilization and optimal results without affecting the edibility of the gelatin. However, during sterilization, the edible gelatin is exposed to the external environment. Prolonged use can lead to airborne bacteria or dust and bacteria brought on by workers, affecting sterilization. Therefore, sterilization cannot be performed in a closed environment using a combination of high temperature and ultraviolet light to minimize airborne contamination. Utility Model Content

[0005] The purpose of this invention is to provide a sterilization device for the production of edible gelatin, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0008] The stirring device includes a motor and a rotating shaft coaxially connected to the output shaft of the motor. The rotating shaft extends into the sterilization chamber, and side plates are provided at the positions where the two ends of the rotating shaft are in contact with the inner wall of the side end of the sterilization chamber. A scraper is provided between the ends of the two side plates, and a stirring plate is provided on the scraper.

[0009] A sealing strip is provided on the lower surface of the top cover near the sealing gasket. An annular groove is provided on the top of the sterilization chamber corresponding to the sealing strip. A feed pipe communicating with the inside of the sterilization chamber is provided on the upper surface of the top cover. A sealing plug is provided in the feed pipe. A pressure relief pipe is provided through the middle of the sealing plug. A pressure relief cap is provided on the top of the pressure relief pipe.

[0010] Furthermore, a water inlet pipe communicating with the heating chamber is provided near the top left side of the front face of the sterilization chamber, and a drain pipe communicating with the heating chamber is provided near the bottom right side of the front face of the sterilization chamber. Both the water inlet pipe and the drain pipe are equipped with sealing plugs at their ends.

[0011] In this invention, the water inlet pipe facilitates the replenishment of aqueous solution into the heating chamber, and the drain pipe helps to drain liquid from the heating chamber when it is not in use, reducing the impact of long-term internal liquid storage on the next heating use. With the cooperation of the sealing plug, the water inlet pipe and the drain pipe are sealed to reduce the outflow of liquid during use and affect the heating use.

[0012] Specifically, the sterilization chamber has support legs at the four corners on its lower surface, and an exhaust pipe connected to the heating chamber is located near the top right side of the front surface of the sterilization chamber. The exhaust pipe is welded and fixed to the sterilization chamber, and the interior of the exhaust pipe is connected to the interior of the sterilization chamber.

[0013] In this invention, the supporting legs lift the entire device, and with the help of the exhaust pipe, the internal exhaust is facilitated when the heating chamber is continuously heating, so that the pressure of the heating chamber is consistent with that of the external environment. With the help of the exhaust pipe, the sterilized edible gelatin solution inside the sterilization chamber is discharged and collected in a centralized manner. In addition, the exhaust pipe is sealed to prevent the internal material from being discharged during sterilization, which would affect sterilization.

[0014] It should be noted that the motor is fixedly connected to the sterilization chamber by screws, the output shaft of the motor is welded and fixed to the rotating shaft, the rotating shaft is rotatably connected to the sterilization chamber, the side plate is welded and fixed to the rotating shaft, and the outer wall of the side plate is tightly fitted to the inner wall of the sterilization chamber.

[0015] In this invention, the motor is connected to an external power source via a wire, and a control switch on the outer wall of the motor is activated. The output shaft rotates, driving the rotating shaft to rotate, thereby achieving the rotation and cooperation of the side plate and continuously providing the power for stirring.

[0016] Furthermore, the scraper is trapezoidal in shape, and both ends of the scraper are welded and fixed to the corresponding side plates. The length of the stirring plate is adapted to the length of the scraper. The bottom of the stirring plate is bonded and fixed to the top of the scraper. Several inclined plates are provided between the stirring plate and the rotating shaft, and the inclined plates are distributed at equal intervals.

[0017] In this invention, a scraper scrapes the edible gelatin adhering to the inner wall of the bottom of the sterilization chamber, preventing it from sticking to the bottom and affecting the uniform mixing. With the cooperation of two stirring plates, the internal materials are mixed. Multiple inclined plates are used to increase the contact area with the materials, thereby achieving uniform mixing and preventing the bottom materials from not being exposed to the light from above, which would cause uneven sterilization.

[0018] Specifically, the lower surface of the top cover is provided with inserts near the four corners, and each insert is provided with a fastening bolt. The top of the sterilization box is provided with a slot corresponding to the insert. The fastening bolt passes through the top cover and the insert and is threaded to the screw hole at the bottom of the slot.

[0019] In this invention, the insertion of the insert and the slot facilitates quick insertion and connection between the top cover and the top of the sterilization chamber, and with the help of the fastening bolts, the top cover and the sterilization chamber are stably combined and fixed.

[0020] It is worth noting that the top of the sealing gasket is bonded and fixed to the bottom of the top cover, the width of the outer wall of the sealing gasket is adapted to the width of the inner wall of the sterilization chamber, the top of the sealing strip is bonded and fixed to the bottom of the top cover, the width of the outer wall of the sealing strip is adapted to the width of the inner wall of the annular groove, and the top of the ultraviolet lamp is fixedly connected to the top cover by screws.

[0021] In this invention, the sealing gasket is inserted into the top of the sterilization chamber to increase the internal sealing. With the help of the sealing strip, the sealing of the top cover and the sterilization chamber assembly is further increased. The two ultraviolet lamps are electrically connected to an external power source through wires. When the control switch on the ultraviolet lamp is activated, the edible gelatin inside the sterilization chamber is sterilized by ultraviolet light.

[0022] The top cover has symmetrical handles on both sides, which provide leverage points to facilitate opening or installation.

[0023] Secondly, the feed pipe is bonded and fixed to the top cover, the inner diameter of the feed pipe is adapted to the outer diameter, a limiting groove is opened in the middle of the top of the sealing plug, the pressure relief pipe passes through the sealing plug, the pressure relief cap is inserted and matched with the top of the pressure relief pipe, a limiting ring is provided at the bottom of the outer wall of the pressure relief cap, and several air outlet holes are opened on the outer wall of the pressure relief cap near the bottom.

[0024] In this invention, the sealing plug is inserted into the feed pipe to seal the interior. The sealing plug is detached from the feed pipe, allowing the edible gelatin to be sterilized to be conveniently added to the sterilization chamber through the feed pipe. During continuous high-temperature sterilization, the thermally expanded air inside the sterilization chamber is discharged through the pressure relief pipe. The pressure relief cap seals the top of the pressure relief pipe. When the internal pressure is within the tolerance range of the sterilization chamber and the top cover, the pressure relief cap seals the top of the pressure relief pipe to reduce air leakage. When the internal pressure exceeds the weight of the pressure relief cap, the air pressure lifts the pressure relief cap to release pressure and exhaust air.

[0025] Furthermore, a ring is provided inside the pressure relief cap near the top, with a through hole in the middle of the ring and several round holes at the top of the side end of the ring. A gasket is provided at the top of the inner wall of the pressure relief cap, with the bottom of the gasket fitting against the top of the pressure relief pipe, and a spring is provided at the top of the gasket.

[0026] In this invention, one end of the spring is bonded and fixed to the washer, and the other end is bonded and fixed to the top of the pressure relief cap. The washer is attached to the top of the pressure relief pipe to seal the end. The gas that needs to be discharged inside pushes up the washer and squeezes the spring. The gas is discharged from the round hole on the ring and from the air outlet to continuously relieve pressure. The pressure relief pipe is slidably inserted into the perforation to facilitate the pressure relief cap to move up and down on the top of the pressure relief pipe.

[0027] Compared with the prior art, the beneficial effects of this utility model are:

[0028] 1. This utility model features a sterilization chamber with a heating compartment. An inlet pipe adds an aqueous solution to the heating compartment, and a heating rod continuously heats the solution after power is applied, thus raising the temperature inside the sterilization chamber. A top cover with a sealing gasket is inserted into the sterilization chamber, and two ultraviolet lamps work together to sterilize the interior with light. A feed pipe allows for easy addition of edible gelatin into the sterilization chamber. The internal heating and light sterilization, combined with the sealed interior, increase sterilization stability. A motor provides power, and with the cooperation of a scraper, stirring plate, and inclined plate, the edible gelatin inside is thoroughly stirred, facilitating the light sterilization process.

[0029] 2. This utility model increases the stability of the top cover and sterilization chamber assembly by setting a sealing strip that fits into the annular groove on the sterilization chamber. With the exhaust pipe, it helps to exhaust air from the heating chamber. The sealing plug is fitted with a pressure relief pipe, and the top is fitted with a pressure relief cap, which helps to continuously relieve pressure inside the sterilization chamber. The pressure is within the range that the sterilization chamber and the top cover can withstand. The pressure relief cap seals the top of the pressure relief pipe. When the internal pressure is greater than the weight of the pressure relief cap, it is convenient to relieve pressure and exhaust air, reducing the impact of internal thermal expansion.

Sterilization is carried out under ultraviolet light irradiation, resulting in double sterilization.

[0066] The internal heating expansion of the sterilization chamber 1 causes the gas that needs to be expelled to push up the gasket 455 and compress the spring 456. The gas is then discharged from the round hole 454 on the ring 452 and from the vent 450, providing continuous pressure relief to reduce the impact of increased internal pressure on the top cover 4 and the sterilization chamber 1. In addition, the exhaust pipe 12 facilitates exhaust, which helps to heat the aqueous solution inside the heating chamber 16.
