Pecans Drying Equipment

The working principle:
        Our pecans 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 pecans dryer machine 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 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.

The system composition:
        1. Main device (heating system): use less electrical energy to absorb the heat from the air for drying pecans.
        2. Drying chamber: pecans dryer is used for loading materials and for keeping temperature and avoiding heat losses.
        3. Wind/air circulation system: to take the heat to full of the drying chamber and improve the temperature, and to take away the water evaporated from pecan.
        4. Dehumidifying system: drain out the water in the chamber to achieve the purpose of drying.
        5. Waste heat recovery system: the pecans drying equipment has three waste heat recovery systems, which greatly lower the loss of heat.
        6. Drainage system: discharge the condensate water to outside to avoid the increasing humidity of the chamber.
        7. Programmable intelligent control system: automatically adjust temperature, humidity, drying temperature, and intelligent operation according to the most appropriate drying process curve.
        8. Warning system: to set warning parameters based on time, temperature, humidity, etc. according to users requirements.
