JDG-10m² Pharmaceutical freeze-drying machine
A freeze-drying machine usually consists of the following main components:
1. Freezing section: This is one of the most important components in the freeze-drying machine. It includes a refrigeration chamber and a refrigeration system. The freezing chamber is usually a sealed container that can hold the substance to be freeze-dried. The refrigeration system freezes substances by providing a low-temperature environment.
2. Sublimation section: After the freezing process is completed, substances in the freezing chamber will enter the sublimation section. This section includes a heating source, usually an electric heating element or heat exchanger, to provide sufficient energy to directly sublimate solid water into a gaseous state without passing through a liquid state.
3. Vacuum system: The freeze-drying process needs to be carried out in a vacuum environment to better promote the sublimation of moisture. The vacuum system creates a low-pressure environment by removing air and maintaining appropriate pressure.
Product Description
Applications
Vacuum freeze drying technology is currently worldwide most advanced technology for food dehydration processing. Compared with the commonly used drying method, the freeze-dried food produced with this technology features long period of quality assurance, good re-hydration nature, good-looking color, good flavor, taste and high content of nutritious components. The dried food basically remains unchanged in its volume and shape, looks like sponge and has no shrinking. This drying technology can be widely used in process of vegetables, fruits, condiments, aquatic products, biological products, medicine, beverage and etc.
Working principle
The vacuum freeze drying is a drying method for dehydration and preservation of substances. It sublimes the moisture in the pre-processed substance from solid state into gaseous state by -30 centigrade quick-freezing under the vacuum condition.
JDG series vacuum freeze drying equipment mainly includes food pre-freezing system, drying bin system, heating system, vacuum system, refrigerating system, material conveying system, medium system, pneumatic system, cleaning and sterilizing system.
