Detailed explanation of the composition and functions of chocolate coating machine

1. Feeding system
-Function: Transport the product to be coated to the processing area.
-Composition:
-Vibration disk/conveyor belt: Smooth conveying of products (such as cookies, soft candy) to ensure continuous feeding.
-Sorting device (optional): Automatically arrange product directions to improve coating uniformity.

2. Preheating zone
-Function: Preheat the surface of the product to prevent chocolate cracking due to temperature differences during coating.
-Composition:
-Infrared heater/hot air circulation system: precise temperature control (usually 40-50 ℃), removing surface moisture.

3. Coating area
-Function: Apply melted chocolate evenly to the surface of the product.
-Type:
-Immersion type: The product is lifted after being immersed in the chocolate trough.
-Waterfall style: The product forms a wrapping layer through a chocolate liquid curtain.
-Spray type: High pressure nozzle atomizes chocolate, suitable for complex shapes.
-Key components:
-Chocolate melting pot: Constant temperature heating (45-50 ℃) with stirring to prevent crystallization.
-Scraper/Rotating Screen: Control Coating Thickness.

4. Drainage and leveling system
-Function: Remove excess chocolate to ensure a smooth surface.
-Composition:
-Vibration screen: high-frequency vibration to discharge excess liquid material.
-Air knife device: Compressed air blows the edges of the product to prevent dripping.

5. Cooling and solidification system
-Function: Rapid cooling to solidify chocolate crystals and maintain their luster.
-Composition:
-Multi layer cooling tunnel: segmented temperature control (such as 12 ℃ → 8 ℃ → 5 ℃) to avoid sudden cooling cracking.
-Cold air circulation unit: with humidity control to prevent condensation.

6. Conveyor system
-Function: Product transportation that runs through the entire process.
-Design points:
-Stainless steel mesh belt/food grade plastic belt: corrosion-resistant and easy to clean.
-Variable frequency speed regulating motor: matching the optimal conveying speed of different products.
