Granulation and coating technology are widely used in pharmaceutical, chemical, food and other industries to improve the characteristics of products in many aspects.
Granulation technology is most widely used in wet granulation, and coating technology is most widely used in spray coating.
Materials with larger particle sizes, such as tablets and pills, are often mixed by wet granulation or mixed wet granulation and tableting and are usually coated by an efficient coating machine.
Materials with smaller particle sizes, such as pellets and powders, are often granulated and coated by fluidized bed granulation/coating machines. Fluidized bed granulation, also known as one-step granulation or boiling granulation, is mixing, granulating, drying, and coating in one device.
The wetting agent or binder in the granulation process and the coating agent liquid in the coating process all need to be atomized and sprayed. The adjustability of the atomizing ability of the spray guns of general granulators and coating machines is very large, and the use of the appropriate liquid flow rate is essential to maximize the production efficiency.
Due to the diversity of raw and auxiliary materials, it is difficult to set a unified standard for liquid flow. Generally, it needs to be mastered through experience and determined through experiments; this requires accurate and wide adjustment of the flow of the liquid pump. Due to hygienic requirements, in addition to changing the liquid, the liquid pump needs to be cleaned and disinfected regularly in the daily production process. Since the coating agent is generally composed of a variety of materials and usually contains a certain amount of particulate matter, this also places special requirements on the
Dosing Pump.
The liquid transmitted by the
programmable precision liquid metering pump only touches the hose, and only needs to replace the hose to meet the hygienic requirements. The transmission of liquid containing particulate matter is its outstanding feature. It also has a wide flow adjustment capability and high flow accuracy. The best choice for this type of application.
