0.4m2 Household freeze dryer WK-HF4, also known as home freeze dryer, is a small vacuum freeze dryer. Apply to the family, online shop a family freeze dryer, widely adapted to fruits, meat, vegetables, Chinese herbal medicines, health products, etc. freeze-drying. Lyophilization or freeze drying is a process in which water is removed from a product after it is frozen and placed under a vacuum, allowing the ice to change directly from solid to vapor without passing through a liquid phase. The process consists of three separate, unique, and interdependent processes; freezing, primary drying (sublimation), and secondary drying (desorption). The Advantages of Freeze Drying It's been known for many years that the Freeze Drying process is better than canning, freezing, and dehydrating! The freeze drying process causes no damage to the nutrition of the food being preserved. Other food preservation methods like canning and dehydrating use higher temperatures that can destroy more than half of the food's nutritional value. Also, the freeze drying process retains the aroma, flavor, color, shape and nutritional content, and does not shrink or toughen the food. Labsnova Home Freeze Dryer Features 1. Stylish appearance, small size and exquisite; 2. Transparent plexiglass door for easy observation of the lyophilization process; 3. SUS304 stainless steel material plate and liner, safe and secure; 4. Acrylic door with flexbile hinge to ensure vacuum degree 5. Import of key components, low noise, high capacity, high quality and high performance; 6. Touch screen operation, one-button start, automatic control of freeze- drying process, easy and convenient; 7. The freeze-drying process can be set and adjusted in real time, and the freeze-drying data and freeze-drying curve can be displayed. 8. Advanced system, low operating current and low energy consumption; 9. One-button fast defrosting technology, over temperature automatic protection. 10.Commercial grade vacuum pump with low noise (oilless vacuum pump is optional) Mini Freeze Dryer Parameters Model WK-HF1 WK-HF4 WK-HF6 Capacity 1-2kg 4-6kg 6-8kg Temperature of cold trap -40℃ Ultimate vacuum 10pa Shelf dimensions 145*275mm 195*425mm 345*425mm Number of shelves 3 4 4 Shelf area 0.1 0.4m2 0.6m2 Shelf spacing 45 45 45 Rated power 750w 1100w 2300w Power supply 110-220v/50hz-60hz Unit dimensions 400*500*700mm 550*800*850mm 720*710*1135mm Weight 50kg 162kg 220kg Labsnova is your turn-key-online shop for superior scientific instruments and lab distillation, extraction, lyophilization equipment.

The pump adopts gas ballast valve which can well rule out water vapor. The gas ballast can fill the air for exhaust compartment, which can reduce vapor ultimate partial pressure, the vapor will be removed. So the gas ballast can well remove the vapor in the pump oil, which can prolong the pump service time and prevent the mix for oil and water vapor.
