Heat pump technology is used in the air conditioning systems of individual and industrial areas in most of our country. With the developing of technology, the heat pump which is spreading to the world every day has been used in different areas. With the analysis of the negativity of fruits and vegetables by traditional methods, Manufacturers prefer drying systems with a heat pump. We compiled all the questions in your head about Ekotec’s drying solutions.

1. What is Fruit, Vegetable Dryer Heat Pump?

Ekotec Fruit, Vegetable Dryer Heat Pump is a device like a fridge, from a cool environment (Environment temperature) to a hot environment (dryer cabin) by using mechanic energy to transfer heat. The food desiccant heat pumps can be used to dry the drying cabinet up to 65 ° C and provide efficient drying. Ekotec food-drier heat pumps are offered for commercial users and save on drying time and energy efficiency.

2. How is the working principle of Dryer Heat Pump?

As in an air-source heat pump, the working conditions of the fruit and vegetable dryer heat pumps are almost similar. The internal components of the evaporator, compressor, condenser and expansion valve consist of 4 main parts. The working cycle of our system is realized by the fans first. The air comes in through the fans on the outside of our heat pump and enters the compressor first. It discharges to the four-way valve as superheated steam with high pressure on the compressor. The four-way valve carries out the transfer to the condenser for heating. It becomes vaporous in condensation and becomes liquid here. The working fluid is then drawn through the expansion valve to the low-pressure line. Here, the expansion valve moves back to the house by spraying the liquid gas. The evaporating air in the evaporator is sent to the compressor for re-compression and the cycle is completed. In this process, the water contained in the food or non-food substances that have been dried in the drying cabinet evaporates and adheres to the house. The process is completed by draining the accumulated water.

3. What Can be Dried with a Dryer Heat Pump?

Fruit: Apple, grape, plum, fig, pineapple, blueberry, strawberry, orange, palm, melon, apricot, cherry, kiwi, mango and more
