Ginseng is a perennial herbaceous plant ，The fleshy root of ginseng is a strong tonic that is suitable for adjusting blood pressure, restoring heart function, neurasthenia, and physical weakness,Modern medicine believes that ginseng has an effect onnervous system，cardiovascular system、endocrine system、digestive system、reproductive system、respiratory systemreachsurgeryBoth use and other methods have significant effects，haveIt has the effects of removing phlegm, strengthening the stomach, diuresis, and stimulating. The stems, leaves, flowers, fruits, and processing by-products of ginseng are all raw materials for light industry, which can be processed into commodities such as tobacco, wine, tea, crystals, and paste containing ginseng components.

The traditional processing of ginseng mainly involves sun drying, oven drying, microwave or infrared radiation. Traditional drying is prone to oxidation and mutation, as well as color change, shape shrinkage and deformation. After drying, the hardness is relatively high and it is inconvenient to consume. And it will be damaged due to high temperatureMultiple ginsenosides、Nutrients such as amino acids. Modern freeze-drying technology is developing rapidly, and ginseng freeze-drying machine isFZGA low-temperature freeze-drying vacuum drying equipment independently developed by the freeze-drying machine manufacturing factory, which is a traditional Chinese medicine freeze-drying machine that meets GMP production standards. Satisfy the processing and production of whole ginseng plants, ginseng freeze-dried tablets, and ginseng freeze-dried powder.

Ginseng Freeze Drying Machine Technology-FZGFreeze DryerProgram automatic control:
1) Pre freezing of ginseng: Fresh ginseng that has been cleaned and processed is put into a plate and then enters the freeze-drying machine, where it is frozen at -50 ℃ for 3-5 hours;

2）Pre vacuuming: Pre vacuuming after sufficient pre freezing60min， Maintain a vacuum of around 20pa;

3）One drying: After the pre vacuum is completed, the ginseng enters a drying stage, during which 90% of the solid ice in the ginseng is driedFZGThe freeze-drying machine controls the temperature and vacuum of the material to sublime into gas within the technical range, ensuring that ginseng does not deform, change color, or damage its nutritional components during the process;

4）Analysis of drying: After most of the flowing water drying is completed, there is still a small amount of bound water, which has strong adsorption capacity and requiresThe FZG freeze-drying machine is temperature controlled and operated under a vacuum environment of 5-30pa to obtain freeze-dried ginseng with a moisture content of 3%.

The entire drying process of ginseng is carried out duringFZGThe freeze-drying machine runs automatically under program control, effectively retaining the original nutritional components of ginseng and preserving most vitamins according to technical requirements. Its body shape and color remain basically unchanged, and it has good rehydration properties. At the same time, the FZG freeze-drying machine is suitable for freeze-drying medicinal herbs such as cordyceps, Panax notoginseng, bird's nest, Ganoderma lucidum, Cistanche, Tianma, honeysuckle, and saffron, with specific technical solutions supported.
