Pre-freeze-drying treatment: the material to be treated is pre-treated, usually including cleaning, cutting, etc., in order to dry more evenly during the freeze-drying process.2. Freezing: Put the pre-treated material into the freeze dryer, and quickly freeze the material to a low temperature (usually between -50 ° C and -70 ° C) through the refrigeration system. In this process, the water in the material condenses into ice.3. Vacuum environment: After freezing, vacuum is injected into the machine to reduce the air pressure (usually less than 0.1 Torr). A low pressure environment helps to lower the boiling point of water.4. Sublimation: Under vacuum conditions, heat is transferred to the frozen material through heating disks or other heating methods. The ice sublimes directly from solid to gas, and the water does not pass through the liquid phase and is quickly removed.5. Collection of water vapor: The water vapor produced in the sublimation process is guided to the condenser, where due to the low temperature, the water vapor is condensed into water and collected to prevent its reflux.6. Drying completion: After a period of sublimation, the water in the material is basically removed, and the final product is dry.Return to normal temperature: After drying, gradually return to normal temperature to complete the entire drying process.Operation screenUnique designAfter a lot of practice and experiments, we have improved the operation screen of vacuum freeze-drying machine. In the past, we designed the screen below the front of the equipment or above the acrylic door opening and closing, but after a lot of user experience feedback, we carried out an innovative design, we designed the screen on the top of the freeze-drying machine, and the screen can be freely flipped 90°, so the design is more beautiful. It also ADAPTS to the needs of the actual operation.Mode selectionStandard mode (Fool mode) and expert modeSmall food freeze-drying machine provides two modes, the ordinary mode and the expert mode, the ordinary mode internal prefab freeze-drying formula, the operator can directly choose the corresponding freeze-drying process can be operated, because the freeze-drying process is affected by many factors including environmental temperature, material size and the composition of each material structure, if the formula cannot be freeze-dried, Users need to enter expert mode to explore and modify the formula. Expert mode allows the addition and modification of freeze-dried formulations and can be enabled if the user is familiar with the equipment and the freeze-drying process.One click defrost functionAccording to the actual needs of some users, after the freeze-drying is completed, a part of the ice and snow inside the cold trap is melted, and the one-click defrost function can be opened. The inside of the cold trap will start to heat up, so that the internal snow and ice will melt, and the melt water will flow out of the drain through the pipe.
