Description

Technical Field

[0001] This utility model relates to the field of food processing technology, specifically to a high-pressure sterilization device for food processing. Background Technology

[0002] Autoclaves play a vital role in the food industry, especially in noodle production. Their main function is to kill microorganisms and enzymes in products through high temperature and high pressure, thereby extending the shelf life of products and ensuring food safety. Packaged food is placed in an autoclave, and then the can is sealed. Steam or hot water is injected into the can to raise the internal temperature to a certain value, usually between 121°C and 134°C. After reaching the required temperature, it needs to be maintained for a period of time to ensure thorough sterilization.

[0003] According to a public announcement of a high-pressure sterilization device for food processing (Announcement No.: CN120052402A), the above application includes a high-pressure sterilization tank and a tank cover installed on the top of the high-pressure sterilization tank. The inner cavity of the high-pressure sterilization tank is provided with a food sterilization carrying mechanism for loading food to be processed. The food sterilization carrying mechanism includes two discs that are symmetrically connected and spaced apart.

[0004] However, in actual use, when food is placed in the sterilization basket, the food in the center heats up slowly, resulting in insufficient heat penetration. This can lead to incomplete sterilization of some parts of the food, leaving microbial residues and affecting food safety. Therefore, we propose a high-pressure sterilization device for food processing. Utility Model Content

[0005] The purpose of this invention is to provide a high-pressure sterilization device for food processing to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-pressure sterilization device for food processing, comprising a high-pressure sterilization tank, a feed inlet at the top of the high-pressure sterilization tank, an insulation sleeve fixedly connected to the outer wall of the high-pressure sterilization tank, and a rotating assembly disposed inside the high-pressure sterilization tank, the rotating assembly comprising:

[0007] The frame has a guide arc plate fixedly connected to its inner bottom surface, and the inner wall of the guide arc plate has a guide arc groove.

[0008] An electric motor, wherein a rotating shaft is fixedly connected to the output end of the motor, a turntable is fixedly connected to the side wall of the rotating shaft, and a bracket is rotatably connected to the inner wall of the turntable;

[0009] A sterilization basket, wherein a rotating rod is rotatably connected to the inner bottom surface of the sterilization basket, a stirring rod is fixedly connected to the side wall of the rotating rod, and a guide rod is fixedly connected to the side wall of the rotating rod.

[0010] Preferably, a connecting pipe is fixedly connected to the side wall of the autoclave, and the connecting pipe is fixedly connected to an external steam pipe.

[0011] Preferably, the frame is disposed inside the autoclave, and the guide arc groove is wavy.

[0012] Preferably, the motor is fixedly connected to the outer wall of the frame, and the number of turntables is set to two sets, with the two sets of turntables symmetrically arranged on both sides of the bracket.

[0013] Preferably, the sterilization basket is inserted into the bracket, and the center of gravity of the sterilization basket is located below the bracket, so that the top opening of the sterilization basket always faces upward.

[0014] Preferably, a cover is inserted into the top of the sterilization basket, and the guide rod is movably connected to the guide arc groove, which guides the guide rod and the rotating rod, so that the stirring rod rotates repeatedly with a small amplitude.

[0015] Preferably, a hydraulic lifting rod is fixedly connected to the inner bottom surface of the autoclave, and the top end of the hydraulic lifting rod is fixedly connected to the bottom end face of the frame.

[0016] Compared with the prior art, this utility model provides a high-pressure sterilization device for food processing, which has the following beneficial effects:

[0017] 1. This high-pressure sterilization device for food processing uses a rotating component to continuously change the position of the food in the sterilization basket. The inner and outer layers of food are heated alternately, improving heat penetration efficiency, enhancing heat convection, and reducing local temperature differences. The stirring rod generates a small-amplitude reciprocating motion when the sterilization basket rotates, which continuously agitates the food. This agitation helps the food absorb heat more evenly and accelerates the rise in core temperature. Compared with static sterilization or overall rotation, it can more effectively break down the boundary layer around the food, improve heat convection efficiency, accelerate the overall heating process of the food, and reach the target sterilization temperature more quickly.

[0018] 2. The high-pressure sterilization device for food processing uses a hydraulic lifting rod to drive the frame and sterilization basket to move longitudinally inside the high-pressure sterilization tank. This allows the food in different parts of the sterilization basket to continuously exchange positions with steam, breaking the static heating state. This is particularly helpful in accelerating the rise of the core temperature, reducing thermal inertia, and shortening the sterilization time. Attached Figure Description

[0025] like Figures 1-5 As shown, this utility model provides a technical solution: a high-pressure sterilization device for food processing, including a high-pressure sterilization tank 1, a feed inlet 2 on the top of the high-pressure sterilization tank 1, an insulation sleeve 3 fixedly connected to the outer wall of the high-pressure sterilization tank 1, and a rotating assembly 4 inside the high-pressure sterilization tank 1. The rotating assembly 4 includes a frame 401, a motor 402, a rotating shaft 403, a guide arc plate 404, a guide arc groove 405, a turntable 406, a bracket 407, a sterilization basket 408, a cover 409, a rotating rod 410, a stirring rod 411, and a guide rod 412.

[0026] In one embodiment of this utility model, the frame 401 is disposed inside the high-pressure sterilizer 1, and a guide arc plate 404 is fixedly connected to the bottom surface of the frame 401. The inner wall of the guide arc plate 404 is provided with a guide arc groove 405, which is wavy.

[0027] The motor 402 is fixedly connected to the outer wall of the frame 401. The output end of the motor 402 is fixedly connected to the rotating shaft 403. The side wall of the rotating shaft 403 is fixedly connected to the turntable 406. The inner wall of the turntable 406 is rotatably connected to the bracket 407. There are two sets of turntables 406, and the two sets of turntables 406 are symmetrically arranged on both sides of the bracket 407.

[0028] The sterilization basket 408 is inserted into the bracket 407. The center of gravity of the sterilization basket 408 is located below the bracket 407, so that the top opening of the sterilization basket 408 always faces upward. The inner bottom surface of the sterilization basket 408 is rotatably connected to the rotating rod 410. The side wall of the rotating rod 410 is fixedly connected to the stirring rod 411. The side wall of the rotating rod 410 is fixedly connected to the guide rod 412. The top of the sterilization basket 408 is inserted into the cover 409. The guide rod 412 is movably connected to the guide arc groove 405. The guide arc groove 405 guides the guide rod 412 and the rotating rod 410, so that the stirring rod 411 rotates repeatedly with a small amplitude.

[0029] A connecting pipe is fixedly connected to the side wall of the high-pressure sterilizer 1, and the connecting pipe is fixedly connected to an external steam pipe.

[0030] Motor 402 drives shaft 403 and turntable 406 to rotate, further driving bracket 407, sterilization basket 408, and food stored inside sterilization basket 408 to rotate within the autoclave 1. This rotational motion causes the food inside sterilization basket 408 to continuously change position, with the inner and outer layers of food being heated alternately, improving heat penetration efficiency, enhancing heat convection, and reducing local temperature differences. The center of gravity of sterilization basket 408 is located below bracket 407, ensuring that the top opening of sterilization basket 408 always faces upwards. As sterilization basket 408 is rotated by turntable 406... The guide rod 412 enters the guide arc groove 405, which guides the guide rod 412 and the rotating rod 410, causing the stirring rod 411 to rotate repeatedly with a small amplitude. When the sterilization basket 408 rotates, the stirring rod 411 generates a small reciprocating motion, which can continuously stir the food body. This stirring helps the food absorb heat more evenly and accelerates the rise of the core temperature. Compared with static sterilization or overall rotation, it can more effectively destroy the boundary layer around the food, improve the heat convection efficiency, accelerate the overall heating process of the food, and reach the target sterilization temperature more quickly.

[0031] In addition, a hydraulic lifting rod 5 is fixedly connected to the bottom surface of the autoclave 1. The top of the hydraulic lifting rod 5 is fixedly connected to the bottom end face of the frame 401. The hydraulic lifting rod 5 drives the frame 401 and the sterilization basket 408 to move longitudinally inside the autoclave 1, so that the food in different parts of the sterilization basket 408 continuously exchanges positions with the steam, breaking the static heating state. This is particularly helpful in accelerating the rise of the core temperature, reducing thermal inertia, shortening the sterilization time, improving the uniformity of heat distribution, and eliminating temperature dead zones.

[0032] In this invention, during use, the motor 402 drives the rotating shaft 403 and the turntable 406 to rotate, further driving the bracket 407, the sterilization basket 408, and the food stored inside the sterilization basket 408 to rotate within the high-pressure sterilization tank 1. The rotational motion causes the food inside the sterilization basket 408 to continuously change position, with the inner and outer layers of food being heated alternately, improving heat penetration efficiency, enhancing heat convection, and reducing local temperature differences. As the sterilization basket 408 is rotated by the turntable 406, the guide rod 412 enters the guide arc groove 405. The guide arc groove 405 guides the guide rod 412 and the rotating rod 410, causing the stirring rod 411 to rotate repeatedly with small amplitudes. The stirring rod 411 generates small reciprocating motions when the sterilization basket 408 rotates, continuously stirring the food body. This stirring helps the food absorb heat more evenly, accelerates the rise of the core temperature, and improves heat convection efficiency.

[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
