Utilize the low-temperature high-humidity air to blow the surface of frozen products circularly and evenly,keep the food fresh. - details see: https://www.machineto.com/2013-hot-selling-new-equipment-air-defreezer-10244637

Application:

The food processing factories which need frozen food as raw materials, and the companies which need the safe and sanitary unfrozen food with a lower weight-loss rate.

Features:

1.It can make the lost juice be absorbed completely by cells and meat of food during unfreezing process, which can retain the natural color and taste and reduce the loss of nutrition after unfreezing. It also can reduce the weight-loss rate (within 1%), which can help the food processing factories decrease the loss.

2.Sensible fans location and blowing style ensure the air homogeneous in the area of unfreezing and make the foods unfrozen evenly.

3.Improve the sanitary condition of unfreezing environment and prevent the foods from being contaminated again after unfreezing.

4.It can convert to fresh-preserve state automatically after unfreezing, and you can get out fresh food anytime.

5.Low-temperature humidifying device solves the problem that it is difficult to humidify in a lower temperature. When the temperature of unfreezing environment is 25, the humidity can reach 90%.

6.The disinfector(optional) provides some ozone into unfreezing machine before food inlet and after food outlet, which can kill the bacteria inside unfreezing machine and ensure the sanitation in unfreezing area.

7.We adopt the touching screen and PLC to control the electric components. We can input different unfreezing program according to different foods, and the only thing which users need to do is start this progarm.

Comparing different unfreezing methods

Item	Low temperature high humidity air unfreezing	Water unfreezing	Room temp. unfreezing	microwave unfreezing
scope of application	Many foods	Seafood and meat	Many foods	Many foods
Unfreezing quality	High unfreezing quality, juice lose slightly, foods can be frozen evenly	Bad unfreezing quality, juice lose seriously, foods cannot be frozen evenly	Bad unfreezing quality, juice lose seriously, foods cannot be frozen evenly	Unfreezing is very unevenly, over-unfreezing happens a lot
Weight-loss rate	Within 1%	3%~5%	Above 3%	2%3%
Foods' color and taste	Retaining the natural color and taste	Surface color become dark and lose the natural taste	Surface color become dark seriously and lose the natural taste a lot	Retaining the natural color but losing the natural taste a lot, especially the surface
Food sanitation	Has a good performance in eliminating the peculiar smell and killing bacteria. Ensure the hygiene of food	Foods contaminate each other, Bacteria reproduce rapidly, and the hygienic condition is poor	Bacteria in air attach on the food surface often and the hygienic condition is poor	Satisfy the food hygiene requirements

The economic loss brought by weight-loss after unfreezing (calculated as chicken, 10tons/day)

The whole economic benefits lies in the electricity using, water using, labor using, gas using, space using, quality of products and many other aspects, any one of which can lead to a different economic benefits. We take the weight-loss during unfreezing process as example to introduce:

Item	Low temperature high humidity air unfreezing	Water unfreezing	Room temp. unfreezing	microwave unfreezing
Weight-loss rate	About 1%	About3%	About 2%	About2.5%
Weight loss(kg/day)	100	300	200	250
Daily economic loss (Average price: USD 2/kg)	USD200	USD600	USD400	USD500
Monthly economic loss	USD6000	USD18000	USD12000	USD15000
