Vacuum Freeze-drying Equipment Machine for Fruits Seafood etc

Introduction of industrial vacuum drying machine

1. Freeze dryer, is a kind of dehydrator that drying the products in vacuum condition, also is one of the best recognized way to drying products.

2. Freeze-drying works by freezing the material and then reducing the surrounding pressure to allow the frozen water in the material to sublimate directly from solid phase to gas phase. So freeze-drying causes less damage to the substance than other dehydration methods using higher temperatures.

TECHNICIAL SPECIFICATION:

1. Inner diameter of drying pot: 850mm

2. Drying temperature: 90~120 degree

3. Max. vacuum degree of drying: 750mmHg

4. Centrifugal rotational speed: 10~300rpm

5. Quantity of drying basket: 3pcs

6. Cubage of drying basket: 60L/pc

7. Capacity: 40~60kg/batch fresh fruit or vegetable chips

8. Oil content of finished product: <20%

9. Power Supply : 380~460v 50Hz or 60Hz, 12kw

Advantages:

1. Much lower frying temperatures (approx. 90 to 120℃ in practical operation, depending on the product) to maintain flavours and colors

2. Processing products with higher reducing sugar levels in comparison with normal atmospheric conditions

3. Minimizing of health harmful thermal reaction products, such as acrylamide

4. Texture can truly be influenced

5. Evaporation rate will be faster

6. Pressure as a new parameter of control next to retention time and temperature

7. More gentle oil handling

8. Lower steam pressure for drying oil heating systems required than in atmospheric fryers (approx. 8 bar)

9. No drying vapor emission
