The mini coating pan (laboratory / small-batch food & pharmaceutical grade) is a core piece of equipment for forming uniform sugar coatings or thin-film coatings on candies, tablets, pills, and granules. It uses a rotating pan + spray system + hot air drying to achieve smooth, even, and professional finishes — ideal for recipe development, small production runs, and in-store fresh coating.
Perfectly suited for food GMP and pharmaceutical cleanroom requirements.

Core Working Principle
- The coating pan tilts and rotates, creating a uniform tumbling bed of cores (candy centers / plain tablets).
- Peristaltic pump + pneumatic spray gun atomizes coating liquid (sugar syrup, film solution, colorant) and precisely sprays onto the tumbling material.
- Purified hot air passes through the bed, rapidly evaporating solvent/moisture to form a dense, smooth coating layer.
- Negative pressure exhaust removes humid waste gas. PLC closed-loop control of pan speed, air temperature, spray volume, and drying time ensures batch-to-batch consistency.
- For sugar coating, an optional polishing step enhances gloss and moisture resistance.
Basic Structure & Standard Configuration
- Coating Pan: 304 stainless steel (316L optional), adjustable tilt angle (typically 30°–45°), available in perforated / half-perforated / non-perforated designs. Lab models support quick pan interchange.
- Spray System: Pneumatic / airless spray guns, peristaltic pump, liquid reservoir; adjustable atomization particle size.
- Hot Air / Exhaust System: Primary + mid-efficiency filtration, air temperature adjustable 0–80°C, negative pressure exhaust with optional condensation recovery.
- Drive & Control: Variable frequency speed control (pan 3–25 rpm), touchscreen + PLC (Siemens / Fuji / Yaskawa optional), with over-temperature, low-liquid, over-current protection.
- Auxiliary Features: CIP cleaning ports, clean enclosure, mobile casters, fully sealed dust-proof design.
Main Specifications (Lab / Small-Batch Models)
| Model Type | Pan Diameter | Batch / Hourly Capacity | Air Temperature Range | Power |
|---|---|---|---|---|
| Table-Top Mini Lab Model | 300 mm | 0.75–2 kg / batch | 0–80°C | 1.5–3 kW |
| Small Commercial Model | 400 mm | 2–5 kg / batch | 0–80°C | 3–5 kW |
| Mid-Size Small-Batch Model | 600 mm | 10 kg / batch | 0–80°C | 5–8 kW |
Core Advantages
- Excellent Uniformity: Baffle + half-perforated pan design minimizes material abrasion; coating thickness variation < 5%.
- Low-Temperature Efficiency: Precise hot air control prevents softening/deformation of candies or heat-sensitive actives.
- Safe & Compliant: Full stainless steel construction, enclosed operation, meets food GMP standards; CIP cleaning ready.
- Compact Footprint: Table-top models fit on benches; floor-standing small units require only 1–2 m² — no large infrastructure needed.
- Process Flexibility: Supports sugar coating, film coating, enteric coating, light-blocking coating, coloring, and polishing.
Applications (Food-Focused)
- Candies: Hard candy, soft candy, spherical candies, center-filled pieces — sugar coating, color coating, moisture barrier.
- Functional Foods: Pelletized supplements, granules with thin-film coating.
- Pharma: Tablets, small pills — sugar, film, sustained/controlled-release coatings.
- R&D & Small Production: Formula optimization, pilot batches, in-store fresh coating (bakeries / candy shops).
Selection & Operation Tips
- Size for daily output × 1.2 to allow buffer; prioritize interchangeable pan models for lab use.
- Sugar coating: non-perforated / half-perforated pan. Film coating: fully perforated pan for faster drying.
- Maintain stable coating liquid viscosity; clean spray guns regularly to prevent clogging.
- Operate in clean, dry, ventilated area — avoid dust + humidity coexistence.
- Before first use: perform empty run + temperature uniformity validation.
