the De-oiling, Flavoring, and Tilting Hydro setup forms the final "finishing" stage of the production line. This combination ensures that snacks are non-greasy, perfectly seasoned, and handled with minimal manual labor.

1. Tilting Hydro (Centrifugal De-Oiler)

After frying, snacks contain 30% to 40% surface oil. The Tilting Hydro (Centrifugal De-Oiler) uses high-speed rotation to "spin off" this excess oil.¹

• Mechanism: A perforated SS 304 basket spins at 700 to 900 RPM. Centrifugal force throws the oil out through the holes into a collection jacket.²
• The "Tilting" Feature: In older models, workers had to lift heavy baskets manually. The Tilting Model uses a mechanical or pneumatic lever to tilt the entire drum, automatically discharging the de-oiled snacks onto a conveyor or into the flavoring drum.
• Benefits: Reduces oil consumption by ~15%, extends shelf life (prevents rancidity), and ensures the product is dry enough for the flavor to stick.

2. Flavor Applicator (Seasoning System)³

The Flavor Applicator is a precision machine that applies spices, salt, or liquid slurries to the snacks.⁴

• Types:
• Dry Powder Applicator: Uses a screw-feeder to drop a precise amount of masala onto the snacks.
• Slurry Sprayer: Uses a pump and nozzles to spray a mixture of oil and spices (essential for Kurkure or Extruded snacks).
• Control: Usually equipped with a VFD (Variable Frequency Drive) to sync the spice flow with the quantity of snacks passing through.

3. Flavoring Drum (Coating Tumbler)⁵

This is the rotating cylinder where the actual mixing happens.

• Design: A long, horizontal drum (usually 5 to 8 feet) with internal "flights" or baffles.
• Action: As the drum rotates, the internal fins lift and tumble the snacks while the applicator sprays the flavor. This ensures 360-degree coverage without breaking delicate items like potato chips.
• Discharge: The drum is slightly inclined, so the seasoned product naturally moves toward the exit and into the packaging section.⁶
