The main body of thaw is low temperature and high humidity steam，Refrigeration system for auxiliary cooling, and then refrigeration, during the humidification system to control humidity, and the rationality of the parameters of the PLC computer control to achieve reasonable, energy saving.
五、Advantages of making and thawing equipment
1、Equipment self advantage
Advanced technique：Using German technology research and development update。Unique wind and air distribution according to the different time period of the thaw, the use of the sub component to send the wind, and more detailed, more uniform, more accurate to send wind circulation, to ensure the best thawing effect.
Material guarantee：Materials are in line with the requirements of food hygiene 304 stainless steel plate and pipe，this is in order to meet the needs of health and structural strength and service life.
Thawing technology principle is using the low temperature and high humidity in the circulating air blowing thawed products. The products formed on the surface of uniform airflow, through the PLC automatic segmentation thawing temperature and time control to achieve product thawing. Low temperature, high humidity and thawing equipment not only cost savings, more important is maintained the original product features and surface sensory freshness, fully meet the thaw after market selling fresh.
1.Stage control of thawing process
2.Maintain the original color and flexibility of the product
3.Low water loss, minimal protein loss
4.Quick and uniform products, low energy consumption
5. Controlled low temperature, inhibiting the growth of microorganisms
