Sterilization technology and sterilization device for processing instant bean products

Abstract

The invention discloses a sterilization process and a sterilization device for processing instant bean products, and relates to the technical field of food sterilization. When a conveying belt drives bean products to move, high-temperature steam is in contact with the bean products and high-temperature sterilization is carried out, due to the fact that the bean products are not turned over in the conveying process, contact dead angles appear during steam contact, and the bean products are not sterilized uniformly. When the bean products are driven by the conveying mechanism to enter the space between the steam exhaust hoods, the bean products in a moving state pass through the inclined guide plate and the material shoveling plate, and are shoveled and turned over in the moving process, so that high-temperature steam sprayed out of the steam exhaust hoods is uniformly contacted with the surfaces of the bean products, and the situation that the sterilization effect is not ideal due to sterilization dead angles is avoided; meanwhile, the side baffles on the two sides are matched with the shoveling plate and the inclined guide plate, so that the bean products are prevented from falling off from the two sides in the process of shoveling and turning over the bean products.

Description

Technical Field

[0001] The present invention relates to the technical field of food sterilization, in particular to a sterilization process and a sterilization device for processing instant bean products. Background Art

[0002] Ready-to-eat soy products refer to soy products that use soybeans or other beans as the main raw materials. After processing, they can be eaten directly from the bag without additional cooking or heating. These products are convenient, fast, diverse in flavor, and rich in nutrition. They are widely used in snacks, side dishes, and instant meal replacements. Ready-to-eat soy product processing refers to the process of using soybeans or other beans as raw materials and processing them through a series of processes to make convenient foods that can be eaten directly. The processing flow integrates key technologies such as raw material processing, shaping and seasoning, sterilization and preservation. The high-temperature sterilization process of ready-to-eat soy products mainly uses high-temperature and high-pressure sterilization. By precisely controlling temperature, pressure and time, it kills microorganisms and spores while ensuring product safety and quality.

[0003] When the conveyor belt drives the soy products to move and the high-temperature steam contacts the soy products for high-temperature sterilization, the soy products are not turned over during the transportation process, resulting in dead corners when the steam contacts, causing uneven sterilization of the soy products. Summary of the Invention

When the bean products are in motion, they are passed through the inclined guide plate and the scooping plate. During the movement of the bean products, they are scooped up and turned over, so that the high-temperature steam ejected from the exhaust hood evenly contacts the surface of the bean products, avoiding the occurrence of sterilization dead corners, resulting in unsatisfactory sterilization effect. At the same time, the side baffles on both sides cooperate with the scooping plate and the inclined guide plate to prevent the bean products from falling from both sides during the process of scooping up and turning the bean products. The inclined guide plates are symmetrically installed along the axial center position of the horizontal plate and are inclined downward at one end away from the horizontal plate. Side baffles are fixedly installed on both sides of the bottom of the horizontal plate, and the scooping plate is fixedly installed between the side baffles. The top of the scooping plate is an inclined surface.

A motor is fixedly mounted on the outer side of the side support plates, and the output end of the motor is fixedly connected to one end of the transmission roller through a coupling, and the top of the conveyor belt fits tightly against the bottom of the material-scraping plate.

[0011] Preferably, the sterilization chamber includes a connecting chamber, which is fixedly mounted on the top of the frame, an air groove is provided on the top of the connecting chamber, and water guide grooves are provided on the tops of both sides of the connecting chamber, water collecting grooves are fixedly mounted at the water guide grooves on the outside of the connecting chamber, a top cover is fixedly mounted at the air groove on the top of the connecting chamber, an exhaust pipe is fixedly mounted at the center position of the top of the top cover, and inner baffles are fixedly mounted on both sides of the inner wall of the connecting chamber, and the inner baffles cooperate with the guide plate by means of the inclination of the inner baffles and the guide plate, so that the condensed water droplets guided by the guide plate enter the inner baffle, and the air groove and the water collecting groove of the auxiliary connecting chamber are smoothly guided from the air groove to the water collecting groove, so as to avoid the condensed water droplets dripping along both sides of the inner wall of the connecting chamber, resulting in a large amount of water accumulation in the sterilization working area, and absorbing the heat of the high-temperature steam together with the sterilized soy products, affecting the sterilization effect, and the inner baffle is inclined upward at the end away from the connecting chamber.

[0012] Preferably, a guide plate is fixedly installed on the top of the inner wall of the connecting bin, and the guide plate is symmetrically installed along the center position of the axis of the connecting bin, and the end of the guide plate away from the air groove is inclined downward, and the end of the guide plate away from the air groove is tightly fitted with the inner wall of the connecting bin, and the guide plate is located above the inner baffle and there is a gap, and the upward moving high-temperature steam is guided by the guide plate, so that the rising high-temperature steam is guided toward the center position under the action of the guide plates obliquely installed on both sides of the top, and is smoothly introduced from the air groove into the top cover, and finally discharged by the exhaust pipe. At the same time, when condensed water droplets appear after the guide plate contacts the high-temperature steam, the arc-shaped ridges evenly arranged on the bottom are used to cooperate with the inclination of the guide plate to quickly guide the water droplets to prevent the water droplets from gradually increasing and directly dripping on the top of the conveyor belt to contaminate the soy products, and the bottom of the guide plate is evenly provided with arc-shaped ridges.

The top of the guide bar is in contact with the top of the conveying mechanism, and the guide bar is inclined inward at one end away from the stacking bin, and an inclined plate is fixedly installed on the inner wall of the stacking bin. The holes of the inclined plate cooperate with the air holes of the stacking bin, so that air can enter the interior of the stacking bin through the air holes and the holes.

[0018] S4. Steam sterilization: Place the cleaned soy products into the sterilization equipment, and allow the soy products to pass through the interior of the equipment under the drive of the equipment. During the passing process, high-temperature steam is used to contact the soy products, raising the temperature of the soy products and killing the existing bacteria.

[0019] The present invention provides a sterilization device for processing ready-to-eat bean products. It has the following beneficial effects:

[0020] 1. The sterilization device for processing instant bean products cooperates with the scissor plate through the inclined guide plate. When the bean products are driven into the exhaust hood by the conveying mechanism, the bean products in a moving state pass through the inclined guide plate and the scissor plate. The bean products are scooped and turned over during the movement, so that the high-temperature steam ejected from the exhaust hood evenly contacts the surface of the bean products, avoiding the occurrence of sterilization dead corners and resulting in unsatisfactory sterilization effect. At the same time, the side baffles on both sides cooperate with the scissor plate and the inclined guide plate to prevent the bean products from falling from both sides during the scooping and turning process.

[0021] 2. The sterilization device for processing instant soy products cooperates with the inner baffle and the guide plate, and utilizes the inclination of the inner baffle to cooperate with the guide plate, so that the condensed water droplets guided by the guide plate enter the inner baffle, and the air groove and the water collection groove of the auxiliary connecting bin are smoothly guided from the air groove to the water collection groove, thereby preventing the condensed water droplets from dripping along both sides of the inner wall of the connecting bin, causing a large amount of water to accumulate in the sterilization working area, and absorbing the heat of the high-temperature steam together with the sterilized soy products, thereby affecting the sterilization effect.

[0022] 3. The sterilization device for processing instant soy products guides the upward-moving high-temperature steam through the guide plates, so that the rising high-temperature steam is guided toward the center position by the guide plates installed obliquely on both sides of the top, smoothly introduced into the top cover through the air groove, and finally discharged through the exhaust pipe. At the same time, when condensed water droplets appear after the guide plates come into contact with the high-temperature steam, the evenly arranged arc-shaped convex strips on the bottom cooperate with the inclination of the guide plates to quickly guide the water droplets, thereby preventing the water droplets from gradually growing larger and directly dripping onto the top of the conveyor belt, thereby contaminating the soy products.

[0023] 4. The sterilization device for processing instant soy products cooperates with the conveyor belt through a scraper plate. During the movement of the conveyor belt, the scraper plate is used to scrape the surface of the conveyor belt to clean the conveyor belt and prevent the residue of the soy products from contaminating the conveyor belt. At the same time, the guide strips are used to restrict the soy products on both sides when the conveyor belt drives the soy products to be discharged to prevent the soy products from falling from both sides.

[0024] 5. The sterilization device for processing instant soy products cooperates with the air holes of the stacking silo through the holes of the inclined plate, so that air can enter the interior of the stacking silo through the air holes and the holes. When the soy products are stacked inside the stacking silo, the air enters between the soy products to cool them down, thereby preventing the soy products from being piled up and generating high temperatures, which may cause deterioration.

A diversion pipe 8 is fixedly installed on the bottom of the exhaust hood 9. The diversion pipe 8 is connected with the air outlet groove of the exhaust hood 9, and a guide pipe 7 is fixedly installed between the diversion pipes 8. After the conveying mechanism 4 drives the soy products into the sterilization bin 3, the high-temperature steam is guided from both sides of the top of the conveying mechanism 4 to the center position through the exhaust hood 9, so that the high-temperature steam contacts the soy products and performs high-temperature steam sterilization on the soy products. The end of the guide pipe 7 away from the diversion pipe 8 is fixedly connected to the air outlet end of the air pump 5, and a horizontal plate 10 is fixedly installed on the side of the exhaust hood 9 away from the feeding mechanism 2. An inclined guide plate 13 is fixedly installed on one side of the transverse plate 10 close to the feeding mechanism 2.

When the soy product passes between the exhaust hood 9, the shoveling plate 11 cooperates with the inclined guide plate 13. The inclined guide plate 13 first contacts the soy product on the top of the conveyor belt 43, and turns the soy product over during the conveying process. Then, the shoveling plate 11 cooperates to turn the soy product over, so that the soy product is turned over while in contact with the high-temperature steam, so that the soy product is evenly contacted with the high-temperature steam. Side baffles 12 are fixedly installed on both sides of the bottom of the transverse plate 10, and a shoveling plate 11 is fixedly installed between the side baffles 12. The top of the shoveling plate 11 is an inclined surface.

[0043] The second embodiment, based on the first embodiment, see Figures 5 to 7As shown, the conveying mechanism 4 includes side support plates 41, which are fixedly installed on both sides of the inner wall of the sterilization chamber 3, and transmission rollers 44 are rotatably installed between the side support plates 41. The transmission rollers 44 are symmetrically installed along the center position of the axis of the side support plates 41. A conveyor belt 43 is installed between the transmission rollers 44. The transmission rollers 44 are driven to rotate by the motor 42, so that the transmission rollers 44 drive the conveyor belt 43 to run. The conveyor belt 43 is used to cooperate with the feeding mechanism 2 to make the soy products evenly spread on the top of the conveyor belt 43. The motor 42 is fixedly installed on the outside of the side support plate 41, and the output end of the motor 42 is fixedly connected to one end of the transmission roller 44 through a coupling. The top of the conveyor belt 43 is tightly fitted with the bottom of the material copying plate 11.

[0044] The sterilization chamber 3 includes a connecting chamber 31, which is fixedly mounted on the top of the frame 1. An air groove is provided on the top of the connecting chamber 31, and water guide grooves are provided on the tops of both sides of the connecting chamber 31. Water collecting grooves 32 are fixedly mounted on the water guide grooves on the outside of the connecting chamber 31, and a top cover 33 is fixedly mounted on the air groove at the top of the connecting chamber 31. In the sterilization chamber 3, high-temperature steam rises after contacting the soy products and is discharged from the air groove at the top of the connecting chamber 31. The high-temperature gas is discharged through the top cover 33 and the exhaust pipe 34. At the same time, when the high-temperature steam rises, it first contacts the bottom of the guide plate 36, and the inclination of the guide plate 36 is used to guide the rising high-temperature steam, so that the guide plates 36 on both sides cooperate with each other to guide the high-temperature steam toward the direction of the air groove. An exhaust pipe 34 is fixedly mounted at the center position of the top of the top cover 33, and inner baffles 35 are fixedly mounted on both sides of the inner wall of the connecting chamber 31. The inner baffle 35 is inclined upward at one end away from the connecting chamber 31.

[0045] A guide plate 36 is fixedly installed on the top of the inner wall of the connecting bin 31. The guide plate 36 is symmetrically installed along the center position of the axis of the connecting bin 31, and the end of the guide plate 36 away from the air groove is tilted downward. The end of the guide plate 36 away from the air groove is tightly fitted with the inner wall of the connecting bin 31. After the high-temperature steam contacts the guide plate 36, condensed water droplets appear at the bottom of the guide plate 36. While using the inclination to guide the steam, the condensed water droplets are guided to both sides through the arc-shaped convex strips and the inclination, and cooperate with the inner baffle 35 to make the condensed water droplets drip into the inside of the inner baffle 35, and cooperate with the air groove of the connecting bin 31 and the water collecting tank 32 to make the condensed water concentrate in the water collecting tank 32. The guide plate 36 is located above the inner baffle 35 and there is a gap, and the bottom of the guide plate 36 is evenly provided with arc-shaped convex strips.

Workers pour the required high-temperature sterilized soy products into the stacking bin 21, and use the leakage groove at the bottom of the stacking bin 21 to cooperate with the inclined plate 23, so that the inclined plate 23 guides the soy products to the leakage groove position. At the same time, when the soy products are stacked in the stacking bin 21, the inclined plate 23 is used to support the soy products in layers to reduce the pressure on the bottom soy products. At the same time, the air holes of the stacking bin 21 cooperate with the holes on the top of the inclined plate 23, so that air can enter the stacking bin 21 through the air holes and the holes. Between the soy products stacked inside, guide strips 22 are fixedly installed on both sides of the bottom of the stacking bin 21, and the top of the guide strip 22 is in contact with the top of the conveying mechanism 4, and the guide strip 22 is inclined inward at the end away from the stacking bin 21. An inclined plate 23 is fixedly installed on the inner wall of the stacking bin 21, and the inclined plate 23 is inclined downward at the end away from the stacking bin 21. During the movement of the conveyor belt 43, the surface of the conveyor belt 43 is scraped by the scraper plate 24 to clean the surface of the conveyor belt 43. At the same time, the soy products leaked from the leakage trough move into the sterilization bin 3 under the drive of the conveyor belt 43, and the inclination of the guide strip 22 is used to restrict the soy products on both sides. The bottom of the outer side of the stacking bin 21 is evenly provided with air holes, and the top of the inclined plate 23 is provided with holes.

[0047] A sterilization process for processing ready-to-eat soy products consists of the following steps:

[0048] S1. Raw material screening: screening the ready-to-eat soy products that need to be sterilized, removing the damaged or spoiled ready-to-eat soy products from the raw materials, and cutting the qualified soy products according to size;

[0049] S2, raw material cleaning, the cut soy products are sent to the cleaning equipment through the conveyor belt, and the cut soy products are rinsed with clean water to wash away impurities and residues on the surface;

[0050] S3. Preheat the equipment to increase the internal temperature of the equipment to the temperature required for sterilization.

[0051] S4. Steam sterilization: Place the cleaned soy products into the sterilization equipment, and allow the soy products to pass through the interior of the equipment under the drive of the equipment. During the passing process, high-temperature steam is used to contact the soy products, raising the temperature of the soy products and killing the existing bacteria.

[0052] When in use, first add water to the steam generator 6, start the steam generator 6 and the air pump 5, so that the steam generator 6 heats the water to generate high-temperature steam, and uses the pipeline of the air pump 5 to introduce the high-temperature steam into the guide pipe 7, and then send it into the diversion pipe 8 through the guide pipe 7, and finally lead it out from the inside of the sterilization bin 3 through the exhaust hood 9, so that the inside of the sterilization bin 3 is heated to reach a sterilization environment, and then the soy product is poured into the feeding mechanism 2, and the feeding mechanism 2 cooperates with the conveying mechanism 4 to evenly spread the soy product on the top of the conveying mechanism 4, and the conveying mechanism 4 drives the soy product into the inside of the sterilization bin 3, and uses the high-temperature steam to sterilize the soy product, and finally passes through the conveying mechanism 4 and leads it out from the other end.

[0053] After the conveying mechanism 4 drives the soy products into the sterilization bin 3, the high-temperature steam is guided from both sides of the top of the conveying mechanism 4 to the center position through the exhaust hood 9, so that the high-temperature steam contacts the soy products and performs high-temperature steam sterilization on the soy products. During the conveying process, the motor 42 drives the transmission roller 44 to rotate, so that the transmission roller 44 drives the conveyor belt 43 to run, and the conveyor belt 43 cooperates with the feeding mechanism 2 to make the soy products evenly spread on the top of the conveyor belt 43. At the same time, when the soy products pass through the exhaust hood 9, the shoveling plate 11 cooperates with the inclined guide plate 13, and the inclined guide plate 13 first contacts the soy products on the top of the conveyor belt 43, and turns the soy products over during the conveying process. Then, the shoveling plate 11 cooperates to turn the soy products over, so that the soy products are turned over while contacting the high-temperature steam, so that the soy products are evenly contacted with the high-temperature steam.

[0054] In the feeding mechanism 2, workers pour the required high-temperature sterilized soy products into the stacking bin 21, and use the leakage groove at the bottom of the stacking bin 21 to cooperate with the inclined plate 23, so that the inclined plate 23 guides the soy products to the leakage groove position. At the same time, when the soy products are stacked in the stacking bin 21, the inclined plate 23 is used to support the soy products in layers to reduce the pressure on the soy products in the bottom layer. At the same time, the air holes of the stacking bin 21 cooperate with the holes on the top of the inclined plate 23, so that air can enter the soy products stacked in the stacking bin 21 through the air holes and the holes. During the movement of the conveyor belt 43, the surface of the conveyor belt 43 is scraped by the scraper plate 24 to clean the surface of the conveyor belt 43. At the same time, the soy products leaking out of the leakage groove move to the sterilization bin 3 under the drive of the conveyor belt 43, and cooperate with the inclination of the guide bar 22 to restrict the soy products on both sides.

[0055] In the sterilization chamber 3, the high-temperature steam rises after contacting the soy products, and is discharged from the air groove at the top of the connecting chamber 31, and is discharged through the top cover 33 and the exhaust pipe 34. At the same time, when the high-temperature steam rises, it first contacts the bottom of the guide plate 36, and the inclination of the guide plate 36 is used to guide the rising high-temperature steam, so that the guide plates 36 on both sides cooperate with each other to guide the high-temperature steam toward the air groove. At the same time, after the high-temperature steam contacts the guide plate 36, condensed water droplets appear at the bottom of the guide plate 36. While the steam is guided by the inclination, the condensed water droplets are guided to both sides by the arc-shaped convex strips and the inclination, and the inner baffle 35 is cooperated to make the condensed water droplets drip into the inner baffle 35, and the condensed water droplets are concentrated in the water collecting tank 32 through the air groove of the connecting chamber 31 and the water collecting tank 32.
