Application advantages of vacuum feeding machine in capsule filling machine

Since the large-scale application of capsule filling machine to produce hard capsule in China in 1980s, the feeding mode has gone through several processes: from the original manual ladder dumping to conveyor belt conveying, from barrel lifting to positive pressure conveying, from vacuum conveying to automatic vacuum conveying, and also cross layer pneumatic self weight conveying The development of these processes shows the progress of their loading methods with the development of the times Nowadays, in the production of solid preparations in China, except for a few of the capsule filling machines which still use manual ladder or other methods of feeding, they are mainly automatic vacuum feeding machines Compared with other feeding methods, this method has the following characteristics: 1 The hopper and vacuum source are integrated, the structure is compact and tight, no dust pollution, and the noise is low 2 Simple installation, can be installed in any place, only need 220V power supply; 3 Simple operation, automatic vacuum feeding device is not only fast, the conveying capacity can meet the demand of the filling hopper of the capsule filling machine 4 The mechanical cleaning method is used to clean the adsorbate of the filter medium instead of the back blowing method of the compressed air commonly used by similar equipment, so as to avoid the pollution caused by the contact of the compressed air with oil or water pollution This is because the medicine has specific requirements for the compressed air (such as the oil content is less than 0.3%, the dust particle is less than 0.01 μ m), and the compression is also omitted Air pipeline installation and operation costs; 5 Vacuum feeding can basically achieve the problem of layering without mixed materials; 6 It can be applied to a clean workshop with a normal height of 2.7m The application of the automatic vacuum feeding machine in the capsule filling machine has comprehensive characteristics that can not be replaced by other feeding mechanisms, no matter from the practical aspect or from the economic aspect However, if we want to be invincible in the industry, we need to continue to innovate and develop.
