A Manual Discharge Deoiler’s design is engineered for simplicity, durability, and efficient oil separation. Every component is purpose-built to ensure uniform oil removal, ease of operation, and long-term reliability—critical for high-frequency commercial use.
The Manual Discharge Deoiler operates on the fundamental principle of centrifugal force, ensuring consistent, efficient oil separation in four straightforward steps:
Loading Phase: After frying, hot foods (≤80℃) are placed into the centrifugal drum—filled to 2/3 capacity to avoid overloading (which compromises efficiency).
Centrifugation Phase: When the motor is activated, the drum spins at 1,200-1,800 RPM. Centrifugal force pushes denser food particles to the drum’s inner wall, while lighter excess oil is forced through the tiny perforations into the outer collection tank.
Safety Lock Engagement: The lid lock automatically engages during spinning, preventing accidental opening and food splatter—critical for compliance with global workplace safety standards (e.g., OSHA, EU-OSHA).
Manual Discharge Phase: After 1-3 minutes (adjustable based on food type), the motor is turned off, and the lock releases. De-oiled food (with 70%-90% oil removed) is removed from the drum, and the manual valve on the collection tank is opened to drain oil for filtration/reuse or safe disposal.
Compared to colanders, strainers, or low-quality plastic deoilers, the Manual Discharge Deoiler’s structure offers unparalleled benefits:
Uniform Oil Removal: Centrifugal force ensures every piece of food is exposed to consistent pressure, eliminating uneven greasiness (a common flaw in gravity-based tools like colanders).
Space Efficiency: Compact dimensions (typically 60cm×40cm×50cm for 10L models) fit seamlessly in small kitchens, food trucks, or crowded production lines.
