[0004] The existing sterilization device repeatedly sterilizes due to the existence of circulation system, easy to cause gel liquid residue, causes equipment cleaning difficulty to increase, and sterilization effect is poor, and long-term high-temperature circulation affects gelatin product quality. SUMMARY

[0005] The utility model discloses a two-stage sterilization device in gelatin production, which solves the problem of microbial pollution caused by incomplete sterilization in the existing gelatin production process.

[0006] A two-stage sterilization device for gelatin production includes a screw pump, a flow meter, a first T-type mixer, a second T-type mixer, a constant pressure regulating valve, a separation chamber, a condenser, a vacuum pump, and a centrifugal pump. The material inlet is connected to the screw pump inlet via a viewing window. The screw pump outlet is connected to the lower inlet of the first T-type mixer via the flow meter and a first one-way valve. The first steam inlet is connected to the left side of the first T-type mixer via a second one-way valve. The right outlet of the first T-type mixer is connected to the lower inlet of the second T-type mixer via a first sterilization pipeline and a third one-way valve. The second steam inlet is connected to the left inlet of the second T-type mixer via a fourth one-way valve. The right outlet of the second T-type mixer is connected to the separation chamber via a second sterilization pipeline and a constant pressure regulating valve. The bottom of the separation chamber is connected to the material outlet. The top of the separation chamber is connected to the condenser via a pipeline. The bottom of the condenser is connected to the vacuum pump and the centrifugal pump, with the vacuum pump interface higher than the centrifugal pump interface. The condenser contains cooling water pipes, with a cooling water inlet at the bottom and a cooling water outlet at the top.

[0007] The bottom of the separation chamber is connected to a level gauge via a pipeline, and the level gauge is connected to the top of the separation chamber via a pipeline.

[0008] The cleaning water inlet is connected to the cleaning spray ball via a pipeline, and the cleaning spray ball is installed at the top of the separation chamber.

[0009] A first temperature sensor is installed at the end of the first sterilization pipeline.

[0010] A second temperature sensor is installed in the middle section of the second sterilization pipeline, and a third temperature sensor and a pressure sensor are installed at the end of the second sterilization pipeline.

[0011] The working principle and process of this utility model:

[0012] The adhesive solution enters the screw pump through the material inlet via the sight glass. After being pumped out by the screw pump, it passes through a flow meter and the first one-way valve into the first T-type mixer. Steam enters the first T-type mixer through the first steam inlet via the second one-way valve to heat the material to 135°C. Steam then flows out from the right outlet of the first T-type mixer into the first sterilization pipeline for several seconds, using high-temperature instantaneous sterilization to kill microorganisms in the material. After primary sterilization, the material enters the second T-type mixer through the third one-way valve. Steam enters the second T-type mixer through the second steam inlet via the fourth one-way valve to heat the material to 148°C. Steam then flows out from the right outlet of the second T-type mixer into the second sterilization pipeline for several seconds for secondary high-temperature instantaneous sterilization, thoroughly eliminating microorganisms in the material. After secondary sterilization, the material enters the separation chamber through the constant pressure regulating valve, where it is cooled and concentrated, and then flows out through the material outlet at the bottom of the separation chamber.

[0013] The condenser uses a bottom vacuum pump to extract air from the condenser and separation chamber, causing a drop in air pressure within the separation chamber and condenser. This results in a decrease in the boiling point of the moisture in the material within the separation chamber, causing the moisture in the material to turn into water vapor and separate out. The water vapor then enters the condenser through the pipe above the separation chamber and condenses into condensate. The condensate is then extracted and collected by a centrifugal pump at the bottom of the condenser. This process also allows for rapid cooling of the sterilized high-temperature material, preventing a decline in product quality due to prolonged high temperatures.

[0014] A cleaning spray ball is installed at the top of the separation chamber to spray and clean the entire separation chamber during the cleaning process.

[0015] Compared with existing technologies, the beneficial effects of this utility model are as follows:

[0016] Two-stage high-temperature sterilization is adopted. The first stage sterilization temperature is 135 ℃, and the second stage sterilization temperature is 148 ℃. High-temperature steam is used to kill microorganisms such as fungi, bacteria, and molds. The material enters the separation chamber and is instantly cooled in a vacuum environment. This ensures both the effective killing of microorganisms in the adhesive and the preservation of product quality.

[0017] Two-stage sterilization replaces single-stage cyclic sterilization, improving sterilization effectiveness; reducing cleaning difficulties caused by cyclic sterilization; reducing overall equipment uptime; reducing operator time; and improving gelatin production efficiency.

[0023] The cleaning water inlet 21 is connected to the cleaning spray ball 22 via a pipeline, and the cleaning spray ball 22 is installed at the top of the separation chamber 13.

[0024] A first temperature sensor 6 is installed at the end of the first sterilization pipeline 25.

[0025] A second temperature sensor 9 is installed in the middle section of the second sterilization pipeline 28, and a third temperature sensor 10 and a pressure sensor 11 are installed at the end of the second sterilization pipeline 28.

[0026] The working principle and process of this embodiment:

[0027] The adhesive solution enters the screw pump 2 through the viewing window from the material inlet 1. After being pumped out by the screw pump 2, it passes through the flow meter 3 and the first one-way valve 23 and enters the first T-type mixer 5. Steam enters the first T-type mixer 5 through the first steam inlet 4 and the second one-way valve 24 to heat the material to 135 ℃. The steam then flows out from the right end outlet of the first T-type mixer 5 and enters the first sterilization pipeline 25 for several seconds, using high-temperature instantaneous sterilization to kill microorganisms in the material. After primary sterilization, the material enters the second T-type mixer 8 through the third one-way valve 26. Steam enters the second T-type mixer 8 through the second steam inlet 7 and the fourth one-way valve 27 to heat the material to 148 ℃. The material then flows out from the right end outlet of the second T-type mixer 8 and enters the second sterilization pipeline 28 for several seconds for secondary high-temperature instantaneous sterilization, thoroughly removing microorganisms from the material.

[0028] The air inside the condenser 15 and the separation chamber 13 is extracted by the bottom vacuum pump 18, causing the air pressure inside the separation chamber 13 and the condenser 15 to drop. This causes the boiling point of the water in the material in the separation chamber 13 to drop, and the water in the material turns into water vapor and is separated out. The water vapor enters the condenser 15 through the pipe above the separation chamber 13 and is condensed into condensate. The condensate is extracted and collected by the centrifugal pump 19 at the bottom of the condenser 15. At the same time, it can quickly cool down the high-temperature material after sterilization and prevent the product quality from deteriorating due to prolonged high temperature.

[0029] A cleaning spray ball 22 is installed at the top of the separation chamber 13 to spray and clean the entire separation chamber 13 during the cleaning process.
