Low Temperature and High Humidity Thawing Machine-Bellows Structure

1. The working principle of the thawing machine is to use air as the medium, and to use a two-pronged approach of lowering the temperature and increasing the humidity to allow high-humidity air to thaw the frozen products to avoid the occurrence of surface drying. 2. The low-temperature and high-humidity thawing machine is composed of a refrigeration system, an air circulation system, a steam heating system, and a temperature and humidity control system. During the thawing process, it can provide sufficient reflux time for the juice inside the meat, so that the juice inside the meat and related nutrients can be retained. 3. The thawing method of the low-temperature and high-humidity thawing machine is gentle and slow, and will not cause major changes in the quality and structure of the meat. The quality of the thawed meat is highly guaranteed. 4. The low-temperature and high-humidity thawing machine adopts a fully automatic control method, which can adjust the thawing time, temperature, humidity, etc. according to the requirements of different frozen products, so as to ensure that the thawing effect and time are in the best state, and automatically switch to a refrigerated and fresh-keeping state after the meat is thawed. 5. From the temperature point of view, the low-temperature and high-humidity thawing equipment has been maintained at a low temperature, which makes the temperature difference between the center and surface temperature of the food small, and the thawing effect is more uniform while avoiding the massive reproduction of microorganisms. On the basis of uniform thawing, the original nutritional components and fresh quality of the meat are maintained, achieving the purpose of high-quality thawing.

A. Insulated warehouse body:
1. Thawing room wall panel: Double-sided stainless steel 304, self-extinguishing flame-retardant polyurethane sandwich insulation board in the middle
2. Thawing room door: Manual sliding cold storage door, double-sided stainless steel 304 steel plate, self-extinguishing flame-retardant polyurethane sandwich insulation board in the middle

B. Heating, humidification, and air distribution system:
1. A thawing fan is used to control the air circulation in the thawing room;
2. Heating method: An electric heating steam generator is used to form low-pressure steam through decompression atomization and release it to the thawing room through the pipeline. At the same time, the temperature in the warehouse is sensed by the thermostat to control the steam inlet, so as to adjust and control the temperature in the warehouse.
3. Humidification method: A high-pressure humidification system is used to humidify the thawing machine with isenthalpy. The humidity in the warehouse is monitored in real time through the humidity controller. If it is lower than the set value, the humidification system will work and provide humidity to the warehouse. When the set value is reached, the humidification system will stop working.

C. Refrigeration system:
The refrigeration unit adopts an Emerson Copeland integrated air-cooled refrigeration compressor, a Danfoss brand expansion valve, and a well-known brand refrigerant. The refrigeration pipeline meets the requirements of Freon refrigeration installation, and the pipeline insulation adopts rubber-plastic insulation pipe without gaps to ensure the insulation effect.

D. Electrical control:
1. It adopts Kunlun Tongtai touch screen + Siemens brand PLC, Chinese interface operation, simple and intuitive operation, can display the real-time change curve of the center temperature of air and meat during the thawing process, and has historical records for viewing. Display the thawing operation time and control the thawing status, with a 4-point timing function.
2. Parameter setting: Thawing is controlled in stages, and the temperature and thawing time in each stage can be set. At the same time, the center temperature requirements of the thawed products can be adjusted according to the thawing requirements, so that the thawed products meet the production process requirements.
3. The system has the ability to store 5 sets of thawing process parameters, and the set parameters can be directly called according to the specifications of the thawed products. Simplify process input.
4. The control system is equipped with a high-temperature alarm device. If the temperature in the thawing room exceeds the temperature set by the system, the system will automatically alarm and remind the operator to deal with it immediately. If the system is not adjusted for more than 1 minute, the equipment will automatically enter the shutdown state to ensure that the raw materials in the warehouse are not damaged.
5. Equipped with advanced Internet of Things alarm devices, when the equipment fails, remote alarms can be realized through SMS or APP platform to remind the relevant person in charge. Avoid major production accidents caused by no one on duty on site.
6. After thawing is completed, the system is equipped with an audible and visual alarm to remind the operator. If there is no operation, the system can automatically enter the refrigeration function to keep the thawed products refrigerated and fresh in the warehouse.
7. A stainless steel moisture-proof electric control box is used, and the control components are Schneider brand.

Left and right air outlet
1. Ensure the uniformity of the left and right air outlets
2. Reduce the height requirement of the thawing equipment to the workshop

The core of low temperature and high humidity thawing equipment:
