For drying various raw materials such as food! Moisture in the raw materials is frozen at temperatures below the freezing point, and then the moisture is removed and dried through sublimation while maintaining that state.
Freeze-drying is a method that freezes the moisture in raw materials at temperatures below the freezing point and removes the moisture through sublimation while maintaining that state. The temperature inside the dryer is lowered below the freezing point to freeze the raw materials. After the freezing process is complete, the raw materials are heated from a negative temperature through a shelf in a vacuum state, causing the moisture to evaporate through sublimation. The evaporated moisture is cooled in a cold trap and collected in the form of ice. Finally, the cold trap is heated to discharge the evaporated moisture in liquid form. 【Features】 - Since sublimation occurs from the frozen state, there is little change in shape. - Drying progresses at low temperatures, resulting in minimal changes in components, and preserving color, aroma, flavor, and nutritional value. - It dries in a porous manner, allowing for drying from the inside and achieving low moisture content. - The porous finish provides good reconstitution and solubility. *We also conduct free tests.
