Problems solved by technology

[0003] However, the existing coating is usually made of talcum powder, which has poor moisture-proof and anti-oxidation effects, and it is difficult to achieve a good moisture-proof and anti-deterioration effect after the tablet is coated.
Moreover, the existing coating process is usually to dry the tablet after all the coating is complete, which takes a long time and consumes a lot of energy.

Abstract

The invention discloses a process based on the coating processing of medical tablets. (1) manufacturing a paddle: mixing talc, hydroxypropyl methylcellulose and nano-scale silicon dioxide to prepare a paddle; (2) preheating Tablets: Place the tablets in the coating equipment, spray hot air into the coating equipment through the jet device at the bottom of the coating equipment, and heat the inside of the coating equipment to heat the tablets; (3) Coating. Hydroxypropyl methylcellulose and nano-scale silicon dioxide are added to the coated paddle of the present invention, which not only makes the coating have good moisture-proof, anti-oxidation and anti-corrosion properties, but also effectively keeps the tablets from being oxidized, dampened and deteriorated. , which greatly improves the stability of the tablet; it can also slow down the speed of the outward release of the tablet's medicinal properties, so as to avoid stomach discomfort for the user.

Description

technical field [0001] The invention belongs to the technical field of feed additives, in particular to a process based on the coating processing of medical tablets. Background technique [0002] In the pharmaceutical industry, a layer of coating is generally applied to the outer surface of the tablet. This layer of coating can protect the tablet, prevent the tablet chip from oxidative deterioration, moisture or volatilization, and also conceal the unpleasant taste of the tablet when taking the tablet. Identify and mitigate the effects of dissolution in the human gastrointestinal tract. [0003] However, the existing coating is usually made of talc powder, and the obtained coating has poor moisture-proof and anti-oxidation effects, and it is difficult to achieve good moisture-proof and anti-deterioration effects after the tablet is coated. In addition, the existing coating process is usually to dry the tablet after all the coatings are completely coated, which takes a long ...
