The distributed pellet core pre-coating equipment capable of removing sundries according to claim 7, wherein the first carrying plate (520), the second carrying plate (522) and the third carrying plate (524) are inclined in a staggered mode, and are provided with carrying holes for pellet cores, and the edges of the carrying holes are provided with circular arc transitions; the first V-shaped plate (521), the second V-shaped plate (523) and the second limiting plate (525) are all provided with water passing holes used for passing through water, and the radius of the water passing holes is smaller than that of the carrying holes.

9. A dispersed pellet core precoating method capable of removing impurities is characterized in that: the method comprises the following working steps:

the method comprises the following steps: feeding the pellet cores, and orderly feeding the pellet cores into a separation system (3);

step two: separating the defective products, namely separating the defective products in the pill cores through a separation system (3) to obtain complete pill cores;

step three: transferring the pellet cores, namely transferring the complete pellet cores obtained in the step two to a distributed pre-coating system (5) and placing the whole pellet cores in a dispersed manner;

step four: preparing a pre-coating liquid, adding the medicinal powder and water into a pre-coating liquid preparation system (4), and mixing the medicinal powder and the water together through the pre-coating liquid preparation system (4) to obtain the pre-coating liquid;

step five: pre-coating liquid is transferred, and the pre-coating liquid is transferred from the pre-coating liquid preparation system (4) to the distributed pre-coating system (5) through an external water pump;

step six: flushing dust and preliminarily precoating the pellet core, adding flowing precoating liquid through a distributed precoating system (5), flushing the dust on the pellet core, and simultaneously preliminarily precoating the pellet core;

step seven: soaking and pre-coating, namely adding sufficient pre-coating liquid through a dispersive pre-coating system (5) to soak the pellet cores in the pre-coating liquid to obtain pre-coated pellet cores;

step eight: preliminary drying, namely pumping away the precoating liquid to enable the residual precoating liquid on the precoating pellet core to fall downwards to obtain a preliminary dried precoating pellet core;

step nine: transferring and collecting, and taking the precoated pellet core in the step eight out of the dispersion type precoating system (5) for collection.
