Ingredient Dissolution: This includes the following steps: S11. Adhesive Dissolution: Stir the adhesive and water in a dissolving tank until completely dissolved; S12. Add the main ingredients and auxiliary ingredients, weigh the remaining raw materials into the dissolving tank according to the proportion, and stir until completely dissolved; S2, High-speed emulsification: The liquid obtained in S1 is emulsified at high speed in an emulsifier; S3, Vacuum Degassing: The emulsified liquid is degassed under vacuum.

[0007] S4. Quantitative filling: The liquid material after vacuum degassing in S3 is quantitatively filled into the bubble holes of the aluminum-plastic blister pack. S5. Ultra-low temperature quick freezing: Place the blister pack after filling with liquid into a -100℃ liquid nitrogen tunnel for pre-freezing; S6. Programmatic freeze drying: Transfer the blister packs after ultra-low temperature quick-freezing to the freeze dryer for freeze drying. S7. Aluminum-aluminum sealed packaging: Remove the blister pack from the freeze dryer, cover it with film and cut it on the sealing machine.

[0008] Compared with the prior art, the present invention provides a method for preparing freeze-dried flash-release tablets of Hericium erinaceus polysaccharide, which has the following beneficial effects: The core of this invention lies in solving the moisture absorption problem through a specific adhesive compound, which has the following advantages: 1. Targeted protection: The immediate-release formulation allows the drug to quickly reach and act on the upper digestive tract, exerting a protective effect on the stomach.

[0009] 2. Innovative anti-hygroscopic properties: By optimizing the type and ratio of binders (increasing the proportion of pullulan polysaccharide), the product's anti-hygroscopic ability has been significantly enhanced, solving the core pain point of poor stability of polysaccharide freeze-dried tablets.

[0010] 3. Zero burden on the stomach and intestines: The amount of excipients used is extremely small, avoiding additional stimulation to sensitive stomachs and intestines. Attached Figure Description
