Bottom Discharge De-Watering Centrifuge is a high-automation machine designed for food processing lines where manual lifting of heavy baskets is not possible. Unlike standard "Top Discharge" models where you lift the product out, this machine has a central opening or a hinged bottom plate that opens once the cycle is complete, allowing the dried item to fall directly onto a conveyor belt or into a collection trolley.

1. Technical Specifications (Bottom Discharge Model)

2. How the Bottom Opening Mechanism Works

1. Spinning Cycle: The product (fried snacks, washed vegetables, or seeds) is spun at high speed to remove water/oil.
2. Deceleration: Once drying is finished, the motor slows down the basket to a very low RPM (approx. 5–10 RPM).
3. Opening: A Pneumatic Cylinder or Hydraulic Arm pulls the bottom plate (Base Plate) downwards or to the side.
4. Discharge: * Scraper Type: A mechanical blade (scraper) moves into the basket and pushes the dried item through the bottom opening.
• Full Opening Type: The entire bottom "floor" of the basket moves, allowing the product to fall by gravity.
5. Closing: The bottom plate resets and locks airtight before the next feeding cycle starts.

3. Key Benefits for Food Processing

• Hands-Free Operation: Zero contact between the operator and the food, ensuring maximum hygiene (GMP Standards).
• Continuous Line Integration: This machine is usually placed directly under a continuous washer or fryer and above a flavoring drum or packing conveyor.
• Labor Saving: A single operator can manage a line producing 500+ kg/hr since there is no heavy lifting involved.
• Vibration Isolation: Most bottom-discharge units use a 4-Point Suspension with heavy inertia plates to ensure the machine doesn't move during the high-speed spin.
