High efficiency coating machine is a kind of high efficiency, energy saving, safe and clean mechatronics equipment which can be used for organic film coating, water soluble film coating, slow and controlled release coating for tablets, pills and candies. Coating machine is suitable for pharmaceutical, chemical, food and other industries. According to the pot body material can be divided into stainless steel, copper two kinds. According to the heat exchange efficiency can be divided into hole coating machine, non-hole coating machine two kinds. According to the production capacity, there are two types: production type and experimental type. The latest technology of experimental high-efficiency coating machine has the same machine can coat 0.2kg, 1kg, 3kg, 5kg, 8kg, 13kg capacity, greatly improving the practicality of coating machine applied in research.
