The film coating machine can be applied to the film preparation of traditional Chinese medicine gel paste. Traditional Chinese medicine gel paste is a plaster made by mixing medicinal material extracts, medicinal materials or chemical drugs with a suitable hydrophilic matrix, and then coating it on the backing material.
The following is the film application and film making method of traditional Chinese medicine gel paste:
Preparation of gel paste: Mix the required Chinese medicine ingredients and gel to prepare the gel paste.
Preparation of coating solution: Mix the gel paste and solvent in a certain proportion to form a coating solution.
Coating: put the coating solution into the coating machine, adjust the parameters of the coating machine, such as coating speed, coating pressure, etc., according to the required coating thickness and coating speed. Start the Film Applicator to allow the coating solution to be evenly coated on the substrate. Different application methods can be used, such as knife coating, spraying, etc.
Drying: After the coating is completed, the substrate is placed in a drying chamber for drying so that the coating solution forms a firm film on the substrate.
Adhesion: Adhere the prepared gel film to the substrate such as medicinal patch to form a traditional Chinese medicine patch.
Test: Test the prepared traditional Chinese medicine patch, such as adhesion, drug release performance, etc.
In short, the film coating machine can realize the effective coating of traditional Chinese medicine gel paste, improve production efficiency and product quality. During the coating process, the parameters of the coating machine need to be adjusted reasonably to achieve the required coating thickness and coating quality. Through subsequent processes such as drying and bonding, the required traditional Chinese medicine patch can be obtained.
