Vacuum Cooling Machine For Vegetable And Fruits - China

price: contact company for price

Working Principle

Vacuum cooling machine is based on the phenomenon that water starts boiling at lower temperature as the pressure decreases. In the vacuum chamber, the pressure is reduced to a level where water starts boiling at 2 celsius. The boiling process takes away heat from the product. As an effect, products can be cooled down to 1 or 2 celsius within 20- 30 mins.

Vacuum Cooling Machine Features

1. Maintain freshness and nutritions greartly.

2. Cool the products to 0- 5 degrees in 30 minutes and prolong the shelf life.

3. Uniform cooling style. ( the core and the surface reach exactly the same temperature)

4. No wilting because of low water loss rate( 1.5- 3% ) .

5. Cure the surface demage of the vegetables and stop their worsening.

6. Energe cost saving because of high effiviency.

7. Never frozen delicate vegetables.

Main Components

1. Vacuum System

The main part of vacuum system is vacuum pump which removes the air of the chamber. The working efficiency of vacuum cooling machine is effected by the vacuum pump. So we choose the the top brand Leybold vacuum pump as the standard.

2. Vacuum Chamber

Size of the chamber is defined by the quantity of produces. And it is made of steel in order to endure the huge pressure difference in and out of it.

3. Refrigeration System

Refrigeration system of our vacuum cooling machine mainly consists of compressor, evaporator, condenser, refrigerant, expansion valve, filter dryer ect. Function of the refrigeration system is to condense water vapour to liquid water in vacuum chamber to avoid water vapour saturating. Because water stops evaporating if water vapour saturates and then the produce stop temperature reducing.

4. Control System

The specific developed control system ensures the machine works perfect, even with partial loading. The target temperature will be realized quickly, without freezing of the delicate vegetables. The processing data are collected in the system, and all relevant processing parameters can be seen on the display.

Our vacuum cooling machine can be started with one push on the button! The touch screen display is very easy to operate and user friendly. The menu will be supplied in the local language.
