6 Shelves Digital Fruit Drying Machine
Various methods must be adopted to control the pressure in order to achieve the best conditions for product drying. The main methods of pressure control are:
1. Separating valve control method
2. Water vapor condenser control
The water vapor condenser control method refers to an operation method that increases the temperature of the water vapor condenser surface to reduce the condensation capacity, resulting in an increase in the partial pressure of water vapor in the drying box, thereby achieving the purpose of pressure control.freeze dryers
3. Small butterfly valve control method
Small butterfly valve control method refers to the purpose of controlling the pressure in the tank by opening or closing the valve between the water vapor condenser and the vacuum pump intermittently. The small butterfly valve control method uses the signal from the control system to control the opening and closing of the valve. When the pressure is higher than the set value, the valve is opened; when the pressure is lower than the set value, the valve is closed.
4. Aeration method.
