1. Working Principle

The Vacuum Decapsulator machine transforms 4–5bar compressed air provided by outside air source into the high-frequency pulsed vacuum by air-jet. The high-frequency pulsed air continuously keeps drawing capsules inside the working chamber within a certain period. As a result, capsules were opened gradually under the affection of pulsed vacuum; powder inside falls. By flexible forces instead of mechanical forces, halves of capsules keep completely intact without any fragment.

2.Advantages

1)Efficiency:

The actual peak efficiency is determined by capsule models, which means the smaller capsule models are, the higher efficiency is. For example, the efficiency of 0# capsule is 3600 grains per minute

It can save both time and labor by processing exceptional capsules in a instant, whether in large amount or not, which can shorten the processing  and exposure time, decrease possibilities of cross contamination of medical powders, and be bulked at once to ensure its quality and be in accordance with requirements of GMP.

2)Deal with exceptional capsules：

It can deal with most exceptional situations, such as deformation, crushing, scald, adhesion, and strong powder viscosity etc.

In daily production procedure, customers may encounter many different types of exceptional capsules, which mean processing the exceptional capsules, such as friability and adhesion, is more important than normal ones. In addition, customers may develop new productions, among which some has strong powder viscosity or hydroscopic property, or be difficult to bulk, so these multifunctional equipments are necessary.

3)Mould：

This equipment can be applicable to all types of capsule models and used at any time or in any place without changing or adjusting moulds or wearing parts.

It is wasteful to change moulds or adjust equipments in that the number of exceptional capsules is small but always need to change capsules models, which spends more time than processing capsules, and not adapts the actual needs of producing. Moreover, the displacing of moulds and wearing parts can delay work and purchasing them can increase costs as well. In a word, the main requirements of customers are: use and maintain conveniently and efficiently.
