What Is a Standard Coating Pan?

A standard coating pan — also called a conventional or non-perforated coating pan — is a machine used for applying aqueous or organic film coats (or sugar/colour coatings) on solid products such as tablets, pellets, candies or food pieces.
It consists of a circular metal pan (diameter typically between about 15 cm and 200 cm, i.e., roughly 6 to 80 inches) which is mounted at a tilt angle (often ~40°) on a bench-top or frame stand.
The pan rotates around a horizontal axis, tumbling the product inside while spray nozzles apply the coating and heated air dries the film.

How Does the Standard Coating Pan Work?

Below is a summary of its core operating steps:

1. Loading of the Product
   The tablets, pellets, or other items are loaded into the rotating pan. As the pan spins, the items tumble continuously.
2. Coating Solution Application
   A spray system (atomised nozzles) applies the coating solution (film, sugar, colour etc.) onto the items while they tumble.
3. Drying of the Coating
   Heated air is introduced (via immersion sword, tube, or baffled pan diffuser systems) to evaporate solvents, fix the film, and ensure an even coating.
4. Unloading & Collection
   Once the coating process and drying are complete, the coated items are discharged from the pan and collected for further processing or packaging.

Key Application Industries

• Pharmaceutical Industry – for film-coating tablets, masking taste, controlling release, improving appearance.
• Food & Confectionery Industry – coating candies, nuts, food pieces with sugar, chocolate or protective films.
• Nutraceutical & Supplement Industry – coating vitamins, herbal pills, nutraceutical pellets.

Technical Advantages

• Uniform Coating & High Quality Appearance
  The tumbling action combined with spray and drying ensures a uniform coating on every unit.
• Adaptability & Flexibility
  Able to handle a wide range of product sizes (from small tablets to large chewing gums) and coating types (sugar, film, enteric).
• Easy to Clean & Maintain
  Since the standard pan is non-perforated, it is relatively easier to clean of dust or debris compared with perforated drums.
• Lower Breakage Rate
  The gentle tumbling rather than high-velocity impact means less chipping or breakage of fragile items.

Model & Configuration Examples

Note: The above is an example — actual models may vary in size, motor power, heating power depending on capacity and application.

Selection Guide: How to Choose the Right Standard Coating Pan

1. Analyse Product Characteristics

• Shape & Size – Are items small tablets, large pieces, or irregular shapes? The diameter and tilt angle of the pan should match.
• Coating Type & Material – Film coating, sugar coating, chocolate coating? Solvent or aqueous? This impacts the air-heating and spray system requirements.
• Throughput & Batch Size – How many units per batch? This determines the pan size and motor power.

2. Process Requirements & Environment

• Drying Capacity – Ensure the hot-air system (immersion sword/tube/diffuser) is adequate for the coating solution and required drying time.
• Speed & Rotation Control – Variable speed control helps optimise coating for different products (fragile vs robust).
• Structure & Material – Stainless steel construction is a must for hygiene (especially in pharma/food). Non-perforated (standard) versus perforated depends on drying speed and capacity.

3. Equipment Configuration & Environmental Adaptation

• Installation Space – The pan will require sufficient floor and overhead space for tilt and access.
• Clean-in-Place (CIP) / Serviceability – Easy access for cleaning and maintenance is crucial, especially when switching products.
• Compliance & Standards – For pharmaceutical use, machine must meet GMP standards and have proper documentation (IQ/OQ/PQ).

Summary

A standard coating pan remains a reliable, cost-effective solution for coating solid products in pharmaceutical, food, nutraceutical and related industries. Thanks to its simple tumbling mechanism with spray plus heated air drying, it can deliver uniform coatings, handle varied product sizes and types, and integrate smoothly into production lines.
When selecting a standard coating pan, pay close attention to product size & shape, coating material, drying capacity and cleaning/maintenance ease.
