Application of freeze-drying of health product raw materials:

1. Freeze drying of traditional Chinese medicine raw materials, including freeze-dried Tianma tablets: By low-temperature pre freezing and precise vacuum control, the Tianma extract content is retained to be ≥90%The finished product has a complete form and a short reconstitution time; Deer antler powder freeze-dried, using a pulse backfilling system to prevent the powder from flying, combined with nitrogen protection, to achieve ultra-low moisture (≤4%）Extend the shelf life to3Year.

2. Freeze drying of active ingredients in health products, including probiotic freeze-dried powder, and development of specialized protective formula (whey protein)+Trehalose), survival rate after freeze-drying ≥95%Suitable for solid beverages and capsule preparations; Peptide raw materials: using low-temperature analysis process to prevent peptide chain breakage and improve freeze-drying efficiency30%.

3. Functional food freeze-drying includes freeze-dried fruits and vegetable powders, such as freeze-dried durian and freeze-dried blueberries, which retain their natural color and nutritional components and are used as instant beverage and baking ingredients.

Design of freeze-drying process for health product raw materials:

1. Fine control of three-stage freeze-drying

Pre freezing stage: rapidly cool down to below the eutectic point (e.g-30℃ to-50℃), using programmed cooling or liquid nitrogen quick freezing to avoid ice crystal damage to cell structure.

Sublimation drying: Through a vacuum adjustment system (adjustable sublimation rate and vacuum degree), prevent material foaming and splashing, and optimize heat transfer efficiency.

Analysis of drying: precise control of temperature gradient to ensure residual moisture sublimation (usually<3%）.

2. Personalized customization of process parameters

Set the freeze-drying curve (temperature, pressure, time) based on the characteristics of the raw materials, such as using a low-temperature long-term strategy for thermosensitive components and increasing the vacuum degree during the sublimation stage for high sugar raw materials.

Equipped with a freeze-drying endpoint automatic testing system, real-time monitoring of moisture content to avoid excessive drying or residual moisture exceeding the standard.

3. GMPCompliance and efficiency improvement

Equipment equipped withCIP/SIPFunction (optional) to ensure clean production.

Adopting a pulse backfilling system to avoid granular materials/Fly flocculent materials to reduce material loss.
