Description

Technical Field

[0001] This utility model relates to the field of soybean product production, and in particular to a flexible sterilization and cooling unit for the production of multiple varieties of soybean products. Background Technology

[0002] Soy products, as a traditional nutritious food in my country, require sterilization during production to kill pathogenic bacteria such as E. coli and Salmonella, as well as spoilage bacteria, and inhibit endogenous enzyme activity to extend shelf life. After sterilization, rapid cooling is necessary to prevent residual heat from continuously damaging the protein gel structure, which would lead to a deterioration in the product's texture (such as soft tofu becoming hard or dried tofu cracking).

[0003] Currently, most of the sterilization and cooling equipment for soy products on the market is designed for a single product. For example, low-temperature sterilization equipment for soft tofu cannot meet the high-temperature penetration requirements of thick tofu, while strong sterilization equipment for thick tofu can easily damage the texture of soft tofu. Multiple machines are needed to process different products separately, resulting in high equipment investment costs and large production space requirements.

[0004] Moreover, most existing cooling equipment for soy products uses direct spray cooling, which easily leads to water accumulation on the surface of soy products and the growth of bacteria. Some equipment also uses air cooling, but the cooling speed is slow and the local temperature difference is large, making it impossible to balance cooling efficiency and uniformity.

[0005] Therefore, this utility model provides a flexible sterilization and cooling unit for the production of various types of soy products. Summary of the Invention

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-6 This utility model provides a technical solution for a flexible sterilization and cooling unit for the production of various types of soy products: A flexible sterilization and cooling unit for the production of various types of soy products includes a support 1 and a conveyor 2 at the upper end of the support 1. A motor box 21 is set at one end of the conveyor 2 on the top side of the support 1. A variable frequency motor is installed inside the motor box 21, and a reducer is connected to its output end. The variable frequency motor is connected to the conveyor 2 through the reducer to provide transmission power. The transmission speed can be changed by adjusting the speed of the variable frequency motor (i.e., adjustable from 0.1 to 0.5 m / min), thereby adapting to the sterilization and cooling time requirements of different soy products. For example, soft tofu requires slow transmission and long cooling, while thick dried tofu requires fast transmission and short cooling. The dust filter of the hot air blower 38 is removable and cleanable. The chain plate, various air plates and other components of the conveyor 2 are all made of food-grade metal, which is wear-resistant and easy to clean. The top of the support 1 is located at the front of the conveyor 2 and is equipped with a sterilization chamber 3 for high-temperature sterilization of bean products. Multiple top air plates 32 and bottom air plates 36 are symmetrically arranged on the top and bottom of the inner side of the sterilization chamber 3. Multiple sets of side air plates 33 are symmetrically distributed on the inner side wall of the sterilization chamber 3. Each set of side air plates 33 consists of two plates. One side air plate 33 is connected to the top air plate 32 and the other side air plate 33 is connected to the bottom air plate 36. The top air plate 32, side air plate 33 and bottom air plate 36 are all hollow structures. Multiple air nozzles 35 are distributed on the lower surface of the top air plate 32, the upper surface of the bottom air plate 36 and the side of the side air plate 33. During operation, the hot air blower 38 filters the outside air and sends it into the heating chamber 31. After the air is heated by the heating pipe, it is diverted through the side air plate 33 to the top air plate 32 and the bottom air plate 36, and finally sprayed out from the air nozzles 35, forming multi-directional hot air to wrap the bean products and achieve uniform sterilization.

[0023] Temperature sensors 34 are distributed on the upper and lower ends of the inner wall of the sterilization chamber 3 to detect the temperature inside the sterilization chamber 3. A heating chamber 31 is also installed on the top of the sterilization chamber 3. Heating tubes are evenly distributed inside the heating chamber 31, and a second temperature sensor is also installed inside the heating chamber 31. The top of each set of side air plates 33 penetrates through the sterilization chamber 3 and is connected to the bottom of the heating chamber 31. A hot air blower 38 is also installed on the top of the sterilization chamber 3. The air outlet of the hot air blower 38 is connected to the top of the heating chamber 31 through the air supply pipe 37. A removable dust filter is installed at the air inlet of the hot air blower 38. The dust filter can be made of nylon dust filter with a pore size of 50-100μm. It can be disassembled and cleaned regularly to prevent dust from entering. A cooling chamber 4 is located at the top of the support 1, at the rear of the conveyor 2, for cooling the sterilized bean products. A temperature sensor is also installed on the inner wall of the cooling chamber 4. A main water pipe 41 is fixed to the outer side of the cooling chamber 4. Multiple branch pipes 42 are connected to the main water pipe 41. One end of each branch pipe 42 extends through the cooling chamber 4 to its inner top. Atomizing nozzles 43 are evenly distributed at the bottom of the section of the branch pipe 42 extending to the inner top of the cooling chamber 4. The atomized particle size is 50-100μm and the spray angle is 120°. The lower end of the main water pipe 41 is connected to a tap water pipe, and a control valve is installed on the pipe. During operation, tap water is diverted from the main water pipe 41 to the branch pipes 42 and forms a uniform water mist through the atomizing nozzles 43. This water mist comes into contact with the sterilized high-temperature bean products, quickly removing heat. The small water mist particle size allows for natural evaporation, preventing water accumulation on the surface of the bean products.

[0024] The conveyor 2 is also magnetically fixed with a tray 5. The tray 5 has multiple placement slots 51 evenly distributed on it. The placement slots 51 have a hollow structure, which facilitates the penetration of hot air for sterilization and contact with water mist for cooling, further improving uniformity. The conveyor 2 is a plate conveyor with metal chain plates. The bottom of the tray 5 is embedded with a magnet, and the tray 5 is attracted to the chain plate of the conveyor 2 by the magnet. The tray 5 is made of food-grade PP material, which is resistant to high temperature of 120℃ and low temperature of -20℃, and is used to carry bean products. The inner side of the support 1 is provided with a base plate located below the conveyor 2, and the top two sides of the support 1 are symmetrically provided with side plates. The sterilization chamber 3 and the cooling chamber 4 are both installed on the side plates. The base plate and the side plates form a sterilization chamber and a cooling chamber between the sterilization chamber 3 and the cooling chamber 4. The base plate and the side plates cooperate to form a large-area closed sterilization chamber and a cooling chamber with the sterilization chamber 3 and the cooling chamber 4, respectively. This can reduce the loss of hot air and cold air, improve energy utilization, and at the same time prevent external dust from contaminating the soy products.

[0025] The lower end of bracket 1 is also equipped with a PLC control box 6, which has a human-machine interface with a 7-10 inch touch screen. It can select product programs, such as clicking on the sterilization parameters of soft tofu and thick tofu, and display real-time parameters, such as sterilization temperature, cooling temperature, transmission speed, and parameter customization settings, such as manually inputting temperature, time, and equipment start / stop operations. The PLC control box 6 is equipped with a programmable logic controller, i.e., a PLC controller, which adopts the Siemens S7-200SMART series. It can build in a database of process parameters for multiple varieties of tofu products, such as soft tofu: sterilization temperature 65℃, sterilization time 5min, cooling temperature 25℃, and thick tofu: sterilization temperature 90℃, sterilization time 10min, cooling temperature 30℃, etc. It is convenient to switch the sterilization and cooling parameters of different products such as soft tofu and thick tofu with one click.

[0026] The working principle of this utility model is as follows: Before operation, the operator selects or sets the processing parameters of the corresponding type of soy product (e.g., tofu block, the parameters are: transmission speed 0.5m / min, sterilization temperature 95℃, sterilization time 5min, cooling solenoid valve opening 60%) through the human-machine interface, and the parameters are transmitted to the PLC controller. Then, the tofu blocks are placed in the placement slot 41 of the tray 5. The tray 5 is then attached to the chain plate of the conveyor 2 by the bottom magnet. The variable frequency motor is started by the PLC controller. The variable frequency motor drives the conveyor 2 through the reducer. The tray 5 moves towards the sterilization chamber 3 with the chain plate. When tray 5 enters sterilization chamber 3, the PLC controller starts hot air blower 38 and heating tube. Hot air blower 38 sends filtered air into heating chamber 31, and the air is heated to the set temperature by heating tube (temperature sensor 2 monitors in real time; if the temperature is below 95℃, the power of heating tube is increased, and if it is above 95℃, the power is reduced). Furthermore, the high-temperature hot air is diverted by the side air panel 33 to the top air panel 32 and the bottom air panel 36, and then blown evenly onto the tofu blocks through each air nozzle 35 to achieve multi-angle sterilization. At the same time, the temperature sensor 34 monitors the temperature inside the sterilization chamber 3 in real time. After sterilization, tray 5 enters cooling chamber 4 with conveyor 2. PLC controller opens solenoid valve, and tap water is delivered to atomizing nozzle 43 through main water pipe 41 and branch pipe 42 to form water mist sprayed on the surface of tofu blocks. The hollow placement groove 51 allows water mist to contact the bottom of tofu blocks, achieving rapid cooling. Temperature sensor can also be added in cooling chamber 4 to facilitate PLC controller to adjust solenoid valve opening and control water mist flow based on temperature feedback. After cooling is complete, tray 5 is moved out of cooling chamber 4 along with conveyor 2. The operator removes tray 5 to complete the unloading. If it is necessary to switch to producing dried bean curd, simply replace tray 5 with one that has a suitable placement slot 51 for dried bean curd size and call up the dried bean curd parameters (such as conveying speed 0.3m / min, sterilization temperature 100℃, cooling solenoid valve opening 80%) in the human-machine interface to start the production of a new batch.

[0027] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
