Component Specifications

Definition
The pan body is the primary structural component of a coating pan machine, typically a rotating cylindrical vessel designed to tumble and mix solid substrates (like tablets, pellets, or candies) while coating solutions are sprayed onto them. It ensures even distribution and drying of coatings through controlled airflow, temperature, and rotational speed, critical for achieving consistent product quality in pharmaceutical, confectionery, and nutraceutical manufacturing.
Working Principle
Operates on the principle of controlled tumbling and spraying: the cylindrical body rotates on a horizontal axis, causing substrates inside to cascade. Coating solutions are atomized and sprayed onto the tumbling bed, while heated or conditioned air flows through the pan to facilitate drying and film formation, ensuring uniform coating thickness and adhesion.
Materials
Typically constructed from 304 or 316L stainless steel for corrosion resistance, hygiene, and durability. May include polished interior surfaces (e.g., Ra ≤ 0.8 μm) to prevent sticking and ensure easy cleaning. Optional glass viewing windows or ports for process monitoring.

Frequently Asked Questions

What is the purpose of the pan body in a coating pan?

The pan body provides the rotating cylindrical chamber where solid substrates are tumbled and coated with solutions, ensuring even distribution and drying for consistent product quality.

Why is stainless steel commonly used for pan bodies?

Stainless steel (304/316L) offers corrosion resistance, hygiene, durability, and ease of cleaning, meeting strict regulatory standards in pharmaceutical and food manufacturing.

How does the pan body achieve uniform coating?

Through controlled rotation speed and inclination, the pan body creates a cascading bed of substrates, while spraying systems and airflow ensure even application and drying of coatings.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
