With the continuous improvement of living standards, people will put forward higher requirements for the quality of consumer products, environmental protection awareness, health awareness is further strengthened, and the demand for various types of drugs, health products and freeze-dried foods will increase. In order to meet the needs of various pharmaceuticals, bio-health products, freeze-dried foods and solid micro-powder preparations, especially the development of bio-engineering, it will bring about a new upsurge in the development of new drugs and bio-pharmaceuticals, all of which will effectively promote the experiment. The further development of the freeze dryer technology in the room has resulted in the continuous expansion of the application scale and the continuous expansion of application fields....

The food freeze-drying machine consists of a refrigeration system, a vacuum system, a heating system, and an electrical instrument control system. The main components of the food freeze-dryer are drying oven, condenser, freezing unit, vacuum pump, heating/cooling device and so on. The principle of the food freeze dryer is to freeze the items to be dried to below the triple point temperature, and then vacuum the solid water (ice) in the items to directly sublimate into water vapor, remove from the items, make the items dry. After the material is pre-treated, it is sent to a quick-freezing chamber for freezing, then sent to a drying warehouse for sublimation and dehydration, and then packaged in a post-processing workshop. The vacuum system establishes a low pressure condition for the sublimation drying chamber, the heating system provides the sublimation latent heat to the material, and the refrigeration system provides the required coldness to the cold trap and the drying chamber. The equipment adopts high-efficiency radiant heating, the material is heated evenly, adopts high-efficiency catching cold trap, and can achieve rapid defrosting; adopts high-efficiency vacuum unit and can realize oil-water separation; adopts parallel centralized refrigeration system, multi-channel on-demand cooling, working conditions Stable and energy-saving; artificial intelligence control, high control accuracy, easy operation....

It is well known that when using a freeze dryer for the first time, we must thoroughly clean all parts of the dryer. Everyone knows that stainless steel parts are cleaned with ethanol, and organic glass is cleaned with normal saline. Ampoules are cleaned with an ultrasonic cleaner, but what do we need to do before we actually operate the freeze dryer?...

The quality of freeze dryers is one of the biggest concerns for consumers. When we order this lyophilizer in the end, how should we judge the quality of lyophilizer equipment? How to make more effective judgments? The following freeze dryer manufacturers to introduce to everyone....
