Energy saving onion dryer for sale / industrial onion dehydrator processing machine

What is LD Heat Pump Dryer And Working Principle?

Heat pump dryer is use of reverse Carnot principle .With free air to absorb heat and transfer it to the drying chamber, drying room temperature to achieve improved, with the appropriate humidity and dehumidification equipment to achieve dry materials. heat pump dryer Compressor - heat exchangers - Chokes - heat sink (outside the machine) - Compressor and other devices constitute a refrigerant cycle system. Under the action of the compressor in the refrigerant circulating in the system flow, it is done in the gaseous booster compressor heating process (temperature up to 100 ℃), releasing it into the machine dry in room temperature air heated by the heat, while they have been and converted to liquid cooling flow, when it runs out machines, liquid absorbs heat quickly evaporates once again transformed into a gaseous state, while the temperature dropped to minus 20 ℃ --30 ℃, then the air around the heat sink will continuously transferring heat to the refrigerant. Refrigerant continuous cycle to achieve the heat in the air transport to the drying room heating room air temperature to achieve the purpose of dry material.

Comparation:

• Old type traditional drying room
1.Drying process is difficult to meet the requirements of food hygiene;;
2.Much coal dust, and finished goods bleak in clolor;
3.Need to replace coal midway, large labour intensity;
4.During drying, it generates large plenty of gas such as CO2/SO2/soot, with poor working conditions

5.Soot gas for the oven equipment corrosion is serious, short service life.
6.The temperature is difficult to achieve automatic control; Temperature and humidity in

drying process fluctuation is bigger, affect the drying quality.

• High temperature heat pump drying dehumidifying drying room:

1, Drying process completely meet the requirements of food hygiene;
2, Cleaning and hygiene in the good condition, the finished colour and lustre is bright;
3, Automatic control, reduce the labor and the labor intensity;
4, During drying, there is no water/gas/solids generating, the green environmental protection; Good and comfortable working environment .

5, Long service life, low operating cost, good economy;
6, Temperature and humidity is automatic control; Small fluctuations in the temperature and humidity in drying process, the drying quality is stable and reliable.

Features Of Our Dryer:

1.New designed energy saving dryer with two times waste heat recovery.

2.Using our patented technology: circulating heating & dehumidification, broaden the application of a dehumidifier in industrial drying

3.Adopt PLC + touch screen controllers, operation easily and more accurate

4.Adopt programmable control mode, can be set different drying curve, satisfy different kinds material drying methods

5.Multi-functions: drying / cooling / dehumidify

6.Low temperature drying method(15-50°C/60°C/75°C),similar nature drying.

7.During drying, the material does not craze, does not distortions, non-discoloring, never degenerate, non-oxidize, drying completely, with good rehydration, keep nutrient content;

8.Stable operation without being influenced by weather

9.Economical: Heat pump dryer running cost just as 40% of oil dryer, 50% of coal burning boiler, 30% of electric boiler.
