Factors Affecting Freeze Dryer Energy Consumption

The energy consumption of freeze dryer is affected by many factors including raw material type, material loading volume, freeze drying curve, equipment maintenance status and ambient temperature. When the loading amount of food freeze dryer is insufficient, unit energy consumption per kg finished product will rise obviously. If condenser of vacuum freeze drying equipment accumulates thick frost, heat exchange efficiency drops and power consumption increases. Different raw materials have different moisture content, high moisture raw materials consume more electricity during freeze drying. Regular maintenance of vacuum freeze drying equipment and optimized freeze drying curve can effectively cut power consumption. Factories can optimize loading scheme and technological parameters of fruit and vegetable freeze dryer and freeze drying production line, to reduce overall production cost of freeze-dried products.
