Laboratory vacuum freeze freeze dryer of horizontal type with an area of 0.1 m2 weighing 150 kg. The doors of the drying cabinet and the cooled chamber are made of transparent polymethylmethacrylate to monitor the process. The number of shelves is 1. Ideal for research laboratories and experimental productions. The freezer is a technical approach that can freeze aquifers in advance and then elevate the water in vacuum distillation to produce dry powders. After freezing drying, the items will be better for long-term storage, over time, with the addition of water, the product can return to its preliminary state and retain its original chemical and biological characteristics. For thermal material such as antibiotics, vaccines, blood products, enzyme hormones and biological products, lyophilization technology can show…
