Fanghua’s eye-catching technology in China’s coating technology
Recently, the film "Fanghua" directed by Feng Xiaogang was sighed. In addition to seeing young people coming to the cinema, there are still many old people who have come to me to recall their memories. The works are extremely enthusiastic.

Fanghua has passed away, and it is beyond recognition. The years left a trace of vicissitudes on the face of a generation.
Some people have commented that this era is not another manifestation of Fanghua. History is repeated and the fate of reincarnation is only presented in different ways. All we can do is live in the present and live up to the fragrance.
“Is the medicine now no longer a sugar-coated tablet?†Recently, when I was buying cold medicine, some people questioned the pills in the pharmacy. After a conversation with the clerk, the author learned that the sucrose-based drug-coated tablets on the finger-coating layer of the sugar-coated tablets are an extremely early and extremely extensive type of coated tablets.
"The icing has a certain moisture-proof and air-insulating effect, which can be used to cover up the bad odor of the drug. On the other hand, it also improves the appearance, making the patient easy to swallow, and has little effect on tablet disintegration. But now the pharmaceutical factory is basically no longer produced." According to the clerk, tablets that currently require the use of a coating have been basically film coated. This coating technology is more advanced and suitable for diabetic patients and coatings for acid sensitive drugs.
The author learned that the main role of the sugar coating in the sugar-coated tablets is to cover up the taste. Prior to the advent of film coating technology, sugar coatings were used in proprietary Chinese medicines. However, the production process is long, the weight of the film is increased, the quality controllability is too poor, the production environment is very noisy, and it has been slowly eliminated. The pharmaceutical factory chooses to use the film material film with the polymer material as the tablet film.
Compared with sugar-coated tablets, film coating has more advantages, such as more moisture-proof, light-proof, and air-insulating, which can further increase drug stability. At the same time, it can improve the appearance, easy to identify, strong and wear-resistant, not easy to crack, and can resist moisture and heat. Drug tablets, dropping pills, pellets, etc. can be film coated by different processes and equipment.
According to industry insiders, China's film coating technology started late. In the late 1970s, a variety of coating liquids and film coating processes developed by a few medical research units and pharmaceutical companies emerged, and gradually promoted and applied abroad. Advanced film coating technology is far behind. In the mid-1990s, China recognized film coating technology and widely used it, but many pharmaceutical companies have many problems in application due to technical reasons.
With the maturity of China's film coating technology and technology in recent years, some domestic pharmaceutical companies have broken through the technical difficulties, and the use of film coating machine equipment has become more and more extensive. For example, Chutai Pharmaceutical's BY300 film coating machine combines pot heating and hot air circulation system in the pot with the imported spray system to produce a highly effective film coating effect. It is widely used in pharmaceuticals, food, hospitals for tablets, pill coating, polishing, etc., and can also be used in scientific research units to try new drugs.
“The film coating is bright after polishing, and the complete solidified coating produced by the surface sugar crystals can prevent the oxidative deterioration, moisture or volatilization of the chip, and cover the unpleasant taste when the chip is taken.†If yes.
Do not feel that the icing of the icing has passed away, and the film coating has replaced it. I can't help but think of childhood, I used to wrap my parents to eat pagoda sugar. I didn't know that it was a drug to drive mites. I only knew that sweet, light yellow and pink cones were very cute. I felt very satisfied when I ate one. It was available at various stores on the street at the door. In order to taste the sweetness, I often go to the icing outside the pill, and now I want to come full of memories.
