Structured Manufacturing Data (2026)

Coating Pan

Based on aggregated insights from structured factory profiles within the CNFX directory, the standard Coating Pan used in the Machinery and Equipment Manufacturing sector typically supports operational capacities ranging from standard industrial configurations to heavy-duty production requirements.

Technical Definition & Core Assembly

A canonical Coating Pan is characterized by the integration of Pan Body and Drive System. In industrial production environments, manufacturers listed on CNFX commonly emphasize Stainless Steel 316L construction to support stable, high-cycle operation across diverse manufacturing scenarios.

A rotating vessel used to apply uniform coating layers to pharmaceutical tablets through controlled spraying and drying processes.

Product Specifications

Technical details and manufacturing context for Coating Pan

Definition
The coating pan is a critical component within an Automated Pharmaceutical Tablet Coating System where tablets are tumbled while coating solutions are sprayed onto their surfaces. It provides controlled environment for uniform coating application, drying, and polishing of tablets to achieve desired release profiles, protection, and appearance.
Working Principle
Tablets are loaded into the rotating pan, which creates a cascading motion. Coating solutions are atomized and sprayed onto the tumbling tablets while heated air is introduced to facilitate drying. The rotation speed, spray rate, and temperature are precisely controlled to achieve uniform coating thickness.
Common Materials
Stainless Steel 316L, Food-Grade Polyurethane

Reliability & Engineering Risk Analysis

Failure Mode & Root Cause
Coating adhesion failure
Cause: Inadequate surface preparation, improper drying cycles, or contamination from previous batches leading to poor film formation and delamination.
Mechanical seal leakage
Cause: Wear from abrasive coating materials, thermal cycling causing seal hardening/cracking, or improper installation leading to product contamination and batch loss.
Maintenance Indicators
  • Visible coating buildup on pan walls or baffles exceeding 1/8 inch thickness
  • Abnormal vibration or irregular rotation sounds during operation indicating imbalance or bearing wear
Engineering Tips
  • Implement strict surface preparation protocols including proper cleaning, degreasing, and surface profiling before each coating application
  • Establish predictive maintenance program with regular vibration analysis on drive components and infrared thermography on heating/cooling systems
