Industrial Coating Machine Selection Guide and Product Overview (Coating Machine Series)
I. What is a Coating Machine?
A coating machine is specialized pharmaceutical and food machinery used to uniformly coat the surface of tablets, granules, pills, or candies with powder, syrup, or film coating mediums. Its core purpose is to improve product appearance, mask unpleasant odors, prevent moisture and oxidation, or achieve sustained and controlled release of drugs.
Core Types and Working Principles
- Small/Laboratory Coating Machines (BY & BYC Series): These utilize a rotating coating pan to tumble the base materials, combined with hot air drying to cure the coating. They feature a compact structure and intuitive operation, making them suitable for early-stage R&D and small-batch trial production.
- Large High-Efficiency Coating Machines (BG Series): These adopt a fully enclosed, high-efficiency through-flow coating technology. Materials perform complex trajectory movements within a clean coating drum, and the coating medium is evenly sprayed through an atomizing spray gun. Combined with negative pressure hot air through-flow for extremely fast drying, this series is specially designed for standardized mass production with high capacity and for micro/small materials.
II. Detailed Parameter Selection Table for Core Models
We offer a full range of models from laboratory to industrial production, and the equipment materials and structures strictly comply with GMP specifications.
1. Small Series (BY / BYC Series)
| Model Series | Spray Gun System | Applicable Pan Diameter (mm) | Core Features | Applicable Scenarios |
|---|---|---|---|---|
| BY Series | - | 300 - 1000 | Classic and practical model, adopting manual or drip liquid supply. | Laboratory R&D, traditional sugar coating, traditional Chinese medicine pill production. |
| BYC Series | Standard | 400 - 1200 | Adds a professional atomizing spray gun system based on the BY series. | Film coating, fine coloring coating, and production with high requirements for coating uniformity. |
2. Large High-Efficiency Series (BG Series)
| Recommended Model | Capacity Positioning | Automation System | Optional Modules | Core Advantages |
|---|---|---|---|---|
| BG-150E | Medium to Large Mass Production | Fully automatic PLC touch screen | CIP Cleaning / High-Efficiency Dust Removal / Dehumidification | Air duct fluid dynamics optimization, anti-fragmentation, extremely high medium utilization rate. |
| BG Custom Line | Ultra-High Capacity | Industrial-grade central control | Negative Pressure Monitoring / Data Traceability | Deeply customized for micro and small materials, seamlessly connecting upstream and downstream production lines. |
💡 Customized Solution Tips: For the BG series high-efficiency coating machines, we can provide non-standard integration of CIP (Clean-In-Place system) and intelligent temperature and humidity control systems based on your workshop layout, significantly reducing cleaning time during product changeovers.
III. Core Differences Between Different Models
1. Technical Differences Between BY and BYC
- Spray System: The BYC series is equipped with a dedicated atomizing spray gun and liquid supply pump, capable of achieving micron-level atomization of the coating liquid, resulting in an extremely flat coating and saving coating liquid. The BY series usually relies on manual syrup application, which places higher demands on operator experience.
- Process Adaptability: BYC perfectly matches modern high-standard film coating processes. BY demonstrates extremely high cost-effectiveness in traditional sugar coating and polishing processes.
2. Outstanding Performance of the Large BG Series
- Material Adaptability: The BG series (such as BG-150E) has optimized air ducts and mesh holes specifically for micro and small materials, completely solving the problems of fine particle loss or hole blockage during the through-flow coating process.
- Environmental Protection and Safety: Fully enclosed negative pressure operation effectively prevents dust leakage. The optional pulse dust removal system can achieve compliant exhaust emission, protecting the health of operators.
IV. Frequently Asked Questions and Technical Explanations (FAQ)
- Q: How long does it usually take to coat a batch of materials?
- A: Standard pharmaceutical-grade coating operation is a rigorous process involving multiple cycles of spraying, fluidization, and drying. The processing time for a single batch requires at least 2 hours or more to ensure the density and uniform drying of the coating. Claims in the market such as "completing coating in 15 minutes" are unachievable under standard pharmacopoeia and actual compliant production.
- Q: My materials are very small (e.g., pellets). Which machine is suitable?
- A: We strongly recommend choosing the customized BG series. We will equip you with a coating drum having a special aperture and adjust the hot air through-flow mode to ensure that micro-particles do not leak or stick together.
V. Selection Advice Quick Reference
- Limited budget / Traditional sugar coating sampling: Choose the BY Series.
- Film coating / Focus on coating uniformity: Choose the BYC Series (comes with a spray gun).
- Large-scale standardized production / Micro-particles: Choose the BG Series (e.g., BG-150E).
- High-frequency product changeovers / High cleanliness requirements: Choose the BG Series + CIP cleaning system.
