This hot air dryer machine mainly use to dry the products which can stack, then the hot air can go through from bottom to top and dry the products. This one the drying bin is separate, then the dryer machine can match with different bins, or the bins of clients current one. It can dry the products like spices, pepper, cardamom, coffee beans, walnuts etc.

Why heat pump dehydrator?
The new heat pump technology used in the drying industry is a major breakthrough, which saves the operation cost up to 75%. The difference similar as the traditional electric water heater and the heat pump water heater, because heat pump is to transfer the heat in the air from outside to the chamber inside.
Bellowing is the electricity consumption in different dryers:

Open and Closed Loop
Open and closed loop heat pump dryer mean you can choose open or closed loop as your need. Open loop is similar as air conditioner, mainly to use cool dry or hot dry. Closed loop mainly for the dehumidification funtion. Normally choose the closed loop for the begining, because the products with high humidity at the begining. Once the humidity precentage decease, then change to open loop, which use a higher temperature to dry the products until full dried.
Of course, the machine can choose open or closed loop automatically once you set the tempeature and humidity required. For example, for the fish drying, it need to be sealed(no bad odor comes out), and the drying tempeature is around 20C. Then the machine will mainly use closed loop to dehumidify, but if the tempeature is higher than 20C, will chang to open loop automatically to decrease the tempeature, then change back to closed loop once tempeature is down.
