Low Temperature and High Humidity Thawing Machine-Duct Structure

A. Duct main structure
Warehouse: double-sided 304 stainless steel plate, with self-extinguishing flame-retardant polyurethane insulation layer in the middle, including manual sliding door of the same material.

B. Duct environment control system
Circulation system: equipped with a special defrosting fan to force air circulation.
Temperature control system:
The electric heating steam generator produces low-pressure steam, which is sprayed into the duct through the pipeline;
The thermostat adjusts the steam volume in real time to stabilize the warehouse temperature.
Humidification system:
High-pressure isenthalpic humidification device;
The humidity controller automatically starts and stops humidification to maintain the set value.

C. Supporting refrigeration system
Emerson Copeland air-cooled compressor, Danfoss expansion valve, pipelines that meet Freon standards and seamless rubber and plastic insulation.

D. Intelligent control system
Hardware: Kunlun Tongtai touch screen + Siemens PLC, stainless steel moisture-proof electric box, Schneider components.

Functions:
Real-time display/record of air and material temperature curves;
Supports multi-stage thawing parameter presets (temperature/time/core temperature), can store 5 sets of processes;
High temperature alarm and automatic shutdown protection, IoT remote alarm;
Sound and light prompts when thawing is completed, automatically switches to refrigeration for freshness preservation without human operation.

Up and down air outlet
1. The internal space of the thawing equipment has a larger capacity
2. The internal disinfection and cleaning of the thawing equipment is healthier

The core of low temperature and high humidity thawing equipment:
1. Low temperature humidification device to solve the humidification problem in low temperature environment.
2. Uniform and reasonable air distribution device to form uniform airflow organization in the thawing area.
3. Internal sterilization technology of the thawing machine to ensure the food hygiene requirements in the thawing area.
4. Fully automated control, programs can be set according to different thawing products to ensure thawing quality.

This product adopts fully automatic staged control technology. During the thawing process, the temperature difference between the surface and the center of the frozen product is small, which effectively avoids spoilage and ensures high thawing quality and low weight loss rate. By optimizing the air duct structure, juice loss is reduced and nutrients are retained to the maximum extent. The equipment has a built-in sterilization system that meets food hygiene requirements and is equipped with an audible and visual alarm function. If no one is operating, it can automatically switch to the refrigeration and preservation mode. It supports batch thawing, reduces labor costs, and can be remotely managed through cloud technology to improve economic benefits. The equipment can store process parameters, simplify the operation process, has a wide range of applications, and has a high utilization rate. Its advanced technology level is in the leading position in the industry and meets the diverse thawing needs.
