Description

A dry sterilization apparatus for casein production Technical Field

[0001] This utility model relates to the field of food production technology, and more specifically, to a dry sterilization device for casein production. Background Technology

[0002] Casein is a protein polymer formed when milk comes into contact with acid. It is a product obtained from milk and / or dairy products through acidification, enzymatic processes, or membrane separation. Several commonly used casein production processes require sterilization. However, rennet-based casein undergoes acidification after sterilization, unlike acid-precipitated casein and lactic acid fermentation casein which use a cooling process after sterilization. Nevertheless, all of the above casein production processes use wet sterilization.

[0003] Wet sterilization is currently the mainstream operation in casein production. This method offers a quick sterilization process, but its drawbacks include short shelf life and incomplete sterilization of casein. Meanwhile, some manufacturers use dry sterilization, employing a static sterilization method, which is inefficient and fails to achieve timely and effective internal sterilization, indicating significant room for improvement. Therefore, we propose a dry sterilization device for casein production. Summary of the Invention

Detailed Implementation

[0023] As shown in Figures 1 to 4, the present invention relates to a dry sterilization device for casein production, comprising a sterilization chamber 200, wherein the sterilization chamber 200 is generally rectangular in shape, and a sterilization assembly structure is installed on the sterilization chamber 200. The sterilization assembly structure includes sterilization components, a turning device, and a shaking device, wherein the turning device and the shaking device are both located inside the chamber of the sterilization chamber 200.

[0024] The sterilization assembly includes a numbering and feeding tank 240, a pressurizing and mixing tank 220, and an inner tube 270. A mixing regulator 230 is connected between the numbering and feeding tank 240 and the pressurizing and mixing tank 220. Several inner tubes 270 are connected to the pressurizing and mixing tank 220. Several outer tubes 250 are connected between the inner tubes 270 and the numbering and feeding tank 240. A detachable filter plate is installed at the connection between the outer tubes 250 and the inner tubes 270 to filter out some of the casein entering the inner tubes 270 and prevent clogging.

[0025] The turning device includes a dual-axis motor 292, with each of the two output ends of the dual-axis motor 292 connected to a side wheel 290. The side wheel 290 has a triangular cross-section. A transfer wheel 291 is connected to the shaft wall of the output end of the dual-axis motor 292 and the side wheel 290 via a bearing. A screw assembly 294 is installed at the bottom of the transfer wheel 291. A turning cloth 280 is installed inside the sterilization chamber 200 above the turning device. The surface of the turning cloth 280 is coated with a rubber coating. When the bottom side wheel 290 rotates, the turning cloth 280 follows and turns, realizing the purpose of turning and stirring the bottom casein. At the same time, the screw assembly 294 drives the entire turning device to move horizontally, ultimately realizing the horizontal movement inside the sterilization chamber 200 while the side wheel 290 performs the back-and-forth turning operation.

[0026] The agitator includes a reciprocating motor 261, the output end of which passes through the sterilization chamber 200 and is connected to a swing shaft 260. A rubber roller 264 is connected to one side of the swing shaft 260. A metal ring is installed at the bottom of the rubber roller 264 to increase the weight at the bottom, facilitating the swinging of the rubber roller 264 and allowing it to penetrate deep into the bottom of the casein for thorough agitation.

[0027] This invention utilizes dry sterilization, simultaneously sterilizing the casein inside the sterilization chamber 200 while also turning and agitating it. The casein at the bottom is tumbled by the rotating side wheels 290 that drive the turning cloth 280, while the rubber roller 264 located on the upper right of the sterilization chamber 200 is agitated by a reciprocating motor 261. This irregular agitation and stirring of the casein ensures it comes into full contact with the sterilizing gas, vaporized hydrogen peroxide, thus improving the efficiency of dry sterilization.

[0028] Specifically: A base 100 is installed at the bottom of the sterilization chamber 200. Inside the base 100 is a controller for controlling the electric functions of the sterilization components, the turning device, and the whirlpool. A sealing plate 210 for sealing and material feeding / discharging is installed on the sterilization chamber 200. The internal controller is existing technology and can realize the switching and adjustment functions of the electric components on the sterilization components, the turning device, and the whirlpool, so it will not be described in detail.

[0029] Specifically: a gas concentration sensor for detecting gas concentration is installed inside the numerical inspection feeding box 240, and a check valve 241 for feeding is installed outside the numerical inspection feeding box 240. The gas concentration sensor used in this application is a BFN-1 type H2O2 concentration sensor. The check valve 241 prevents gas leakage while feeding, enabling timely replenishment when needed, reducing the occurrence of insufficient sterilization gas concentration inside the sterilization chamber 200 during sterilization, and improving sterilization performance.

[0030] Specifically, the mixing regulator 230 is equipped with a valve 231 for controlling gas flow and pressure detection, and the valve 231 integrates a pressure gauge. This valve 231 is a conventional integrated pressure gauge valve. The mixing regulator 230 is used to mix the gas between the feed tank 240 and the pressurized mixing tank 220 for reuse.

[0031] Specifically: the inner pipe 270 has honeycomb-shaped through holes on its surface for gas discharge. The end of the inner pipe 270 away from the pressurized mixing chamber 220 passes through the sterilization chamber 200 and connects to the outer pipe 250. The through holes discharge sterilizing gas, and several through holes can effectively improve sterilization efficiency. The pressurized mixing chamber 220 is equipped with a pressurization structure, which is existing technology, used to pressurize the internal gas and improve the spraying efficiency.

[0032] Specifically: A plurality of swing wheels 262 are mounted on the outer wall of the swing shaft 260. One end of each swing wheel 262 is connected to a connecting plate 263. The rubber roller 264 is connected to the swing shaft 260 via the connecting plate 263 and the swing wheels 262. The outer wall of the reciprocating motor 261 is fixedly connected to the outer wall of the sterilization chamber 200. The swing shaft 260 is connected to the output end of the reciprocating motor 261 to achieve the swing operation. A sealing structure is provided at the position where the output end of the reciprocating motor 261 connects to the swing shaft 260 inserted into the sterilization chamber 200 to reduce gas leakage during sterilization.

[0033] Specifically: A positioning plate 293 is installed at the bottom of the dual-axis motor 292. The positioning plate 293 is connected to the lead screw assembly 294, and both ends of the lead screw on the lead screw assembly 294 are connected to the inner wall of the sterilization chamber 200. The outer wall of the dual-axis motor 292 is connected to the adapter wheel 291, and the bottom of the adapter wheel 291 is connected to the lead screw assembly 294. The lead screw assembly 294 realizes the horizontal reciprocating movement of the adapter wheel 291 and its connecting structure.

[0034] Working Principle: This embodiment provides a dry sterilization device for casein production. In use, casein is placed in the sterilization chamber 200. The electrical control equipment within the base 100 controls the operation of the sterilization components, the turning device, and the oscillator. Vaporized sterilizing gas is added to the numbering and feeding box 240 through the check pipe 241. After sufficient addition, the gas is mixed by the mixing regulator 230, and then the valve 231 is opened, allowing the sterilizing gas to enter the pressurized mixing chamber 220. After being pressurized by the pressurization structure in the pressurized mixing chamber 220, the gas is output to the inner pipe 270. Several holes on the inner pipe 270 eject the sterilizing gas, simultaneously controlling the output of the reciprocating motor 261 to reciprocate, driving the swing shaft 26... The oscillating wheel 262, connecting plate 263, and rubber roller 264 on the sterilizer 200 swing, with the metal ring at the bottom of the rubber roller 264 increasing the load and agitating the casein. Simultaneously, the output end of the dual-shaft motor 292 at the bottom of the sterilizer 200 rotates, driving the side wheel 290 to rotate, which in turn moves the lead screw assembly 294, causing the covering cloth 280 above to tumble back and forth, turning the casein at the bottom. The sterilizing gas in the sterilizer 200, under sufficient pressure, is discharged through the external pipe 250 into the numbering and feeding box 240 for circulation. After the sterilizing gas is filled, the gas concentration sensor in the numbering and feeding box 240 will detect the real-time gas concentration and alarm if it falls below the set threshold, requiring timely replenishment. After sterilization, the sealing plate 210 is opened to discharge the casein.
