Onion Dryer

Introduction of onion drying machine: 
        The onion dryer from Gongyi Lantian Machanical Plant is new type of dryer, which is innovated from old type chamber dryer. Our onion dryer bring the air source, heat source and new energy technology to the field of drying. So far, it is the most advanced and highest energy-efficiency drying equipment all over the world. And our this dryer has advantages of safty, stability, high energy efficient, environment protection, 24 hours of a day working, etc., and it will take the place of old traditional drying technology at this stage of tension energy suppling.

The principle of onion drying equipment:
        Our onion drying machine is using inverse cano principle, absorbing heat air and transferring them to the drying chamber to realize the increase of temperature in the dryer. Our onion dryer is composed of compressor, heat exchanger, flow controller and heat absorber, and these devices form a cycling system (main drying device and drying chamber). Under the action of compressor, the refrigerant will be flowing circulating in this system. It will finish the process of pressure rising and temperature rising in the compressor (temperature can be up to 95℃), then release high temperature source to heat the air in the chamber, and at the same time, it will be cooled and translated into liquid. When it runs out the onion drying machine, the liqud will aborb hot air quickly and be tanslated to gas again. At the same time, the temperature will be dropped to -20~-30℃, and the heat absorber will transfer the heat source to refrigerant. And the refrigerant tranport the heating source from the air to drying chamber constantly and circularly to heat the air temperature in the chamber.
        Like the air-conditioner and heat pump units, when the onion dryer machine is working, it will absorb the energy QA from low temperature medium in the evaporator. Itself will consume some energy which is compressor consumption energy QB. It will release heat QC in the condenser through medium circulation system. QC=QA+QB. Then the onion dryer working efficiency is (QB+QC)/QB. While, the heating efficiency of other heating device will be less than 1, so the heating efficiency of our high temperature onion drying equipoment is higher than other heating equipment. It can be seen that using our onion drying machine can save energy, also can reduce the discharging of emission of CO2 and other pollutants, to achieve the effect of energy conservation and emission reduction.

The model selection of onion drying equipment:
        1. 3P onion dryer can adapt about 15 CBM chamber, and it will consume 3 degree electric power per hour.
        2. 6P onion drying machine can adapt 25 CBM drying chamber, and it will consume 6 degrees electric power per hour.
        3. 10P onion dryer can adapt 40 CBM drying chamber, and it will consume 12 degrees electric power per hour.
