Essence of Herbal Medicine

The ultimate solution for high-value TCM. Our technology prevents active ingredient degradation, preserving 100% of heat-sensitive compounds and natural shapes for premium medicinal quality.

Locking the Healing Power of Nature.

The freeze-dried Chinese medicinal materials industry is a segmented field of Chinese medicinal materials processing developed relying on vacuum freeze-drying (FD) technology. Its core is to complete the drying process through the “low-temperature pre-freezing + vacuum sublimation dehydration” process without damaging the active ingredients of Chinese medicinal materials, thereby realizing the quality upgrading of Chinese medicinal materials. In recent years, with the advancement of the internationalization of traditional Chinese medicine, the increasing demand of consumers for high-quality medicinal materials, and the maturity of freeze-drying technology, the industry has developed rapidly. Its products are widely used in Chinese medicinal pieces, health products, pharmaceutical preparations and other fields, catering to both the high-end market and export demand, with a compound annual growth rate of 34.6% (2020-2023).

Key Benefits

Tradition Preserved by Science.

Maximum PotencyZero heat damage to sensitive alkaloids, saponins, and volatile oils.

Aesthetic PreservationMaintains the natural size, color, and microscopic structure.

Rapid RehydrationPorous structure allows medicinal components to release faster during decoction.

Long-term StabilityMoisture under 3% prevents mold and oxidation without chemical fumigation.

Industry Pain Points

Although freeze-dried pharmaceutical products have significant advantages in activity retention and stability, the industry still has many pain points. At the same time, compared with ordinary dried pharmaceutical products:mainly hot air drying and spray drying, there are obvious differences between the two, and the disadvantages of ordinary dried pharmaceutical products are prominent:

Common Chinese medicinal materials

High temperatures cause a 30%-50% loss of heat-sensitive components such as saponins and volatile oils. For example, the content of active saponins in ginseng decreases by 60% after drying.
It shrinks severely, has a dull color, is prone to deformation and clumping, and its surface is easily oxidized and discolored.
High moisture content makes it prone to mold and insect infestation, with a shelf life of only 12-24 months.
It has a hard texture, making it difficult to crush and dissolve, and its dissolution rate is slow; in simulated gastric juice, the dissolution rate is only 63.4% after 30 minutes.

Freeze-dried Chinese medicinal materials

Low-temperature freeze-drying retains over 90% of the active ingredients with no significant degradation.
It retains its original shape, has vibrant colors, a loose texture, and is of excellent quality.
Moisture content ≤6%, shelf life at room temperature over 36 months, no preservatives required.
It is loose and porous, easily crushed, and dissolves quickly with a high dissolution rate; in simulated gastric fluid, the dissolution rate reaches 89.7% within 30 minutes.

1. Locking efficacy and preserving shape: Low-temperature treatment can maximize the retention of active ingredients and original shape of medicinal materials, without component degradation and shape shrinkage;

2. Stable quality: The water content can be accurately controlled below 5%, inhibiting microbial reproduction, and the product batch stability is strong;

3. Convenient and efficient: Intelligent PLC control system, which can preset freeze-drying curve, realize full automatic operation, and shorten drying time (for example, traditional drying of Angelica sinensis takes 7 days, while freeze-drying only takes 24 hours);

4. Green and safe: No preservatives or desiccants are needed, and no pollutants are produced during processing, which meets the requirements of modernization and greenization of traditional Chinese medicine.

The Future of Herbal Potency.

Chinese medicinal material freeze dryer (vacuum freeze-drying equipment) is the core equipment for processing freeze-dried Chinese medicinal materials. It is mainly composed of pre-freezing system, vacuum system, heating system and control system. Its working principle is to clean and slice fresh Chinese medicinal materials, pre-freeze them at a low temperature of -30℃ to -50℃ to form ice crystals inside, and then sublimate and dehydrate the ice crystals directly in a vacuum environment, with the whole temperature not exceeding 40℃. Its core advantages are:

Finished Product Form

The core characteristics of freeze-dried Chinese medicinal materials finished products are “retaining the original shape and loose porous texture”, which are specifically manifested as: the appearance is close to the color of fresh Chinese medicinal materials ,such as freeze-dried Panax notoginseng is light brownish yellow, freeze-dried honeysuckle remains white/light yellow, the volume is basically the same as fresh medicinal materials, without obvious shrinkage; the texture is light and loose, can be crushed with light pinching, the section is honeycomb-shaped, and the micro-structure is complete without collapse; the water content is low ,usually ≤6%, no mildew, no caking, and can be stored for a long time at room temperature. The finished products are mainly divided into two forms:

Complete form: such as whole freeze-dried Panax notoginseng and freeze-dried ginseng, used for high-end gifts and processing of medicinal pieces;

Powder form: such as freeze-dried Panax notoginseng powder and freeze-dried wolfberry powder, used for health products and food additives, which can disintegrate quickly when encountering water and have a fast dissolution rate.
