Candy Peanut Chocolate Coating Pan Machine And Polishing Machine

Product Specification

In modern agriculture, slow-release fertilizers are revolutionizing crop management by enhancing nutrient use efficiency, reducing environmental impact, and lowering application costs. The key to producing high-quality slow-release urea granules lies in the precision coating process. Our state-of-the-art Stainless Steel Coating Machine is engineered specifically for this critical task. It delivers unmatched durability, exceptional coating uniformity, and reliable performance, making it the ideal solution for fertilizer producers aiming to manufacture premium, value-added products.

Key Features & Benefits

1. Premium Stainless Steel Construction for Longevity & Purity

• Corrosion-Resistant Build: All parts contacting the product are constructed from high-grade AISI 304 or 316L stainless steel. This ensures superior resistance to corrosion from urea, polymer coating solutions, trace elements, and other chemical agents.
• GMP-Compliant Design: The polished, smooth surfaces and seamless design minimize dead zones, making cleaning quick and effective. This adherence to hygienic standards prevents cross-contamination and guarantees product purity batch after batch.

2. Superior Coating Uniformity for Consistent Product Quality

• Patented Drum Design: The precisely calculated drum angle, rotation speed, and internal baffle (lifter) system work in harmony to create a perfect cascading motion of the urea granules. This ensures every particle is exposed evenly for a consistent coating application.
• Advanced Spray System: Equipped with high-precision, atomizing spray guns, the system delivers a fine, uniform mist of coating liquid. The spray rate and timing are meticulously controlled to form a thin, dense, and uniform film on each granule, which is critical for controlled nutrient release.

3. Intelligent PLC Control for Precision & Reproducibility

• Fully Automated Operation: The machine is integrated with a Programmable Logic Controller (PLC) and a user-friendly Touchscreen HMI. This allows for precise setting and control of drum speed, inlet air temperature, spray pump rate, and process time.
• Recipe Management: The system can store multiple process recipes for different products. With a single tap, operators can switch between formulations, ensuring batch-to-batch consistency, reducing human error, and streamlining production.

4. Energy Efficient & User-Friendly Design

• Integrated Drying System: An efficient hot air supply system quickly evaporates solvents from the coating, shortening the process cycle and reducing energy consumption.
• Dust-Free Enclosed Operation: The fully enclosed design contains dust and minimizes solvent vapor release, ensuring a safer and cleaner working environment that meets environmental standards.
• Easy Maintenance: A modular design for key components simplifies maintenance and reduces downtime, lowering your total cost of ownership.

Working Principle
The urea granules are continuously or batch-fed into the rotating drum. As the drum turns, the internal lifters gently pick up and cascade the granules, creating a homogeneous "particle bed." The precision spray guns atomize the coating solution (e.g., polymer resin, sulfur) and evenly distribute it over the tumbling granules. Simultaneously, heated air is passed through the drum, rapidly drying the coating solution upon contact with each granule. This process forms a solid, continuous film around the core urea particle. The finished, coated granules are then discharged for further cooling or packaging.

Primary Applications
This versatile coating machine is ideal for a wide range of coating applications on granules and pellets, including:

Slow-Release & Controlled-Release Urea Fertilizers: Coating with polymer-based membranes to delay nutrient release.

Sulfur-Coated Urea (SCU): Applying a uniform layer of molten sulfur onto urea granules.

Urea with Micronutrients: Coating granules with essential trace elements like Zinc, Boron, etc.

Anti-Caking Agent Coating: Applying anti-caking powders or liquids to improve storage and flowability.

Other Applications: Seed coating, pesticide granule coating, and coating for various chemical and food products.
