Manufactur standard High Humidity Differential Pressure Pre-Cooling Machine for Vegetable and Fruit for Netherlands Manufacturer

Short Description:

The unit adopt high humidity preservation technology, which can keep the temperature and humidity within the range set by user in normal operating hours. Before the fruits and vegetables are put in storage,the unit store the cool energy of evaporator in the water by water circulation, so as to maintain relatively constant temperature of storage when pre-cooling; then use the fan to drive air cycle; the air saturated with water will keep the humidity of storage within the range of pre-cooling;...

"Sincerity, Innovation, Rigorousness, and Efficiency" is the persistent conception of our company for the long-term to develop together with customers for mutual reciprocity and mutual benefit for Manufactur standard High Humidity Differential Pressure Pre-Cooling Machine for Vegetable and Fruit for Netherlands Manufacturer, "Passion, Honesty, Sound service, Keen cooperation and Development" are our goals. We are here expecting friends all over the world!


The unit adopt high humidity preservation technology, which can keep the temperature and humidity within the range set by user in normal operating hours. Before the fruits and vegetables are put in storage,the unit store the cool energy of evaporator in the water by water circulation, so as to maintain relatively constant temperature of storage when pre-cooling; then use the fan to drive air cycle; the air saturated with water will keep the humidity of storage within the range of pre-cooling; 2~4KPa differential pressure makes the air flow fast so as to cool the fruits and vegetables in the storage to appropriate preservation temperature in short time.

Features of The High Humidity Differential Pressure Pre-cooling Preservation unit
* Patented product, may supply about 00C and 90 percent above humidity in the storage. The shrinkage losses of fruits and vegetables is very small during pre-cooling;
* Defrosting unit is not necessary during pre-cooling operation;
* Distributing air under differential pressure ensure that the temperature drops in short time so as to pre-cool the fruits and vegetables rapidly;
* The unit has good-looking appearance, sealability, high strength and corrosion resistance;
* Adopt axial fan, protection degree of motor IP54, pulse operation, energy efficient;
* Unique humidifying system makes the temperature can be adjusted according to user’s requirement, and has stable and reliable performance;
* Widely suitable for pre-cooling treatment of all kinds of fruits, vegetables and flowers in great batch.

Working Principle of the High Humidity Differential Pressure Pre-cooling Preservation unit
The unit adopt high humidity preservation technology, which can keep the temperature and humidity within the range set by user in normal operating hours. Before the fruits and vegetables are put in storage, the unit store the cool energy of evaporator in the water by water circulation, so as to maintain relatively constant temperature of storage when pre-cooling; then using the fan to drive air cycle; the air saturated with water will keep the humidity of storage within the range of pre-cooling; 2~4KPa differential pressure makes the air flow fast so as to cool the fruits and vegetables in the store to appropriate preservation temperature in short time.
