The drug polishing machine is a capsule and tablet polishing equipment that can remove dust from the surface of capsules and tablets, improve surface smoothness, and is suitable for the production of various capsules and tablets. The equipment mainly consists of a hopper, polishing cylinder, sealing cylinder, brush, coupling, split type bearing seat, motor, distribution box, waste removal head, discharge hopper, and frame. It has the characteristics of novel mechanism, simple operation, easy cleaning, high polishing efficiency, and good cleanliness. All parts that come into contact with drugs are made of stainless steel, and the equipment hygiene conditions comply with GMP standards. Below, the editor will briefly introduce the working principle of the drug polishing machine, as follows:

The working principle of the drug polishing machine is to drive the capsule to make a circular spiral motion along the polishing tube wall through the rotational motion of the brush, so that the capsule advances along the spiral spring. Under the continuous friction with the brush and polishing tube wall, the outer surface of the capsule shell is polished, and the polished capsule enters the waste hopper from the discharge port. In the waste remover, due to the negative pressure, the lightweight unqualified capsules rise under the action of airflow and enter the vacuum cleaner through a straw. The heavier qualified capsules continue to fall and are discharged through the movable discharge hopper, effectively achieving the purpose of polishing and waste removal. The powder and small fragments that are brushed off during the polishing process enter the sealing cylinder through the small holes on the polishing cylinder wall and are sucked into the vacuum cleaner for recycling.
