Automatic Fryums (Pellet) Frying Line is a high-speed industrial setup specifically designed to fry and expand dry pellets (2D/3D shapes) into crispy snacks.  Because fryums expand rapidly (within 15–40 seconds), the line must be perfectly synchronized to prevent over-frying.

1. The Frying Process Flow

The line follows a strict sequence to ensure the pellets expand uniformly and absorb the least amount of oil:

1. Vibratory Feeder with Hopper: Dry pellets are loaded here. The vibrator ensures a consistent, single-layer flow into the fryer to prevent clumping.
2. In-feed Elevator: A "Z-type" or bucket elevator carries the dry pellets from the ground-level hopper to the fryer inlet.
3. Continuous Pellet Fryer: The heart of the system. It features a Submerger Belt that keeps the pellets fully immersed as they expand and float.
4. De-oiling Conveyor: A vibrating mesh belt that removes excess surface oil while the product is still hot.
5. Seasoning & Flavoring Drum: A rotating drum where the "scarf tray" or flavor dispenser sprays spice mix onto the expanded fryums.
6. Cooling Conveyor: Brings the product to room temperature before it reaches the packaging section.⁷

3. Key Machine Details

• External Heat Exchanger: For fryums, indirect heating is critical. Direct flame can cause "hot spots" that burn the delicate pellets. The external exchanger keeps oil quality high and saves fuel.
• Motorized Hood Lifting: The entire top conveyor of the fryer can be raised with a button. This is essential for fryums because they leave "fines" (small starch particles) that must be cleaned daily to avoid fire hazards.
• VFD (Variable Frequency Drive): Allows you to change the speed of the belts. 3D pellets may need 10 seconds more than thin 2D wheels; the VFD allows this adjustment on the fly.
• Continuous Filtration: A bucket or belt-type filter removes particles from the oil every minute, extending oil life and maintaining snack taste.
