At present, the proportion of hard capsules in the pharmaceutical and health care products market is increasing. Capsule filling machines, as their production infrastructure, will also be more widely used, and people's application requirements will also increase. Although the manufacture and technology of domestic capsule filling machines are basically mature, the shortcoming in the United States is the way of loading. The Chinese also respond to them through a variety of feeding methods. In the face of various feeding methods and actual conditions, people will choose how to load. What about?
Since the beginning of the 1980s, the large-scale application of capsule filling machines in the production of hard capsules in the country has gone through several processes: from the original artificial ladder to the conveyor belt, from the barrel to the positive Pressure delivery, from vacuum delivery to automatic vacuum delivery, in addition to cross-layer air control self-weight delivery. The development of these processes shows the progress made by the way of loading and unloading.
At present, in the production of solid preparations in the country, except for a few, the capsule filling machine is still extended by manual ladders or other methods of feeding, and the automatic vacuum feeding machine and the barrel lifting machine are mainly used for feeding, and the two methods are different. With the maturity of the automatic vacuum feeder technology and the structural limitations of the workshop under construction, the automatic vacuum feeder will show a practical side.
However, the purpose of these two feeding methods is to overcome the imperfections in the manual ladder dumping method: (1) Since the mixed powder needs to be placed in a rotating drum and transported to the capsule filling process, The original artificial ladder dumping method, such as the process of loading and unloading, will cause dust to fly, polluting the site, equipment, operators, etc., which is also extremely detrimental to air purification, environmental sanitation, and personnel health. At the same time, the production site and production equipment are not easy to clean, and the filtration system of the purification system is easily blocked or damaged, resulting in poor filtration effect and reduced purification level. (2) In the manual ladder dumping method, the labor intensity of the operator engaged in transportation and ladder dumping is also great.
