Utilize the low-temperature high-humidity air to blow the surface of frozen products circularly and evenly.
The food processing factories which need frozen food as raw materials with a lower water loss rate to keep thawing meat fresh and good taste.
Generally speaking, the working principle is utilizing low-temperature high-humidity clean air blowing the surface of frozen food evenly to make them thawed. The temperature, humidity of unfreezing air and unfreezing time determine the quality of thawed food. To minimum the unfreezing time, prevent juice loss and weight loss in a large scale, decrease the difference between foods’ surface temperature and center temperature, we adopted 3 different stages to thaw and cool preserve. The temperature of first stage is +15°C, and the temperature of second stage is +5°C, while the third stage is for cool preservation and its temperature is -3°C.
Lowtemperature humidifying device: overcome the difficulty which is humidifying in a relative low temperature. When unfreezing temperature is 2~5°C, the relative humidity can reach 90%.
Blowing device: the scientific and sensible blowing device ensures the homogeneous air-flow organization in the area of unfreezing.
Ozonizer: we provide some ozone into the unfreezing equipment before foods’ inlet and after foods’ outlet to kill the bacteria completely and ensure meeting the hygiene requirement.
Touch screen and PLC: we can set different programs according to different unfreezing food
1. High defreezing quality; the difference between central temperature and surface temperature of food can be controlled in the minimum range;
2. Reduce the lost of water; keep nutrition; the weight-lost rate can be controlled within 1%;
3.Controlled by PLC and touch-screen; can be adjusted according to different requirements; easy to operate; Convert to cool keeping stage automatically after defreezing; keep the unfrozen products fresh (good color, good flavor);
4.We adopt high-pressure atomizing device to humidify the low-temperature air; the average humidity can reach 94% during the whole defreezing process.
5. Low temperature environment during the whole defreezing process; the sterilization device is optional;
6. (Option)We can also provide the matching loading carts and special lift platform.
