2. Working Principle of the 1000-Type Chocolate Coating Machine
The 1000-type chocolate coating machine operates through a series of well-coordinated steps:
Step 1: Chocolate Melting & Tempering
- Chocolate is melted in a tempering unit to achieve the ideal viscosity.
- The tempering process ensures proper crystallization, giving the chocolate a glossy finish and snap.
Step 2: Product Feeding
- Items to be coated (e.g., biscuits, nuts) are placed on a conveyor belt that moves through the machine.
- An even distribution system ensures products are properly spaced for uniform coating.
Step 3: Chocolate Application
- The melted chocolate is pumped into a coating curtain or spray nozzle system, covering the products evenly.
- Excess chocolate is removed via air knives or vibrating mechanisms.
Step 4: Cooling & Solidification
- Coated products pass through a cooling tunnel where cold air hardens the chocolate shell.
- The cooling process prevents bloom (white streaks) and ensures a crisp texture.
Step 5: Packaging & Collection
- Finished products are transferred to packaging lines or storage containers.
