Crown’s continuous deodorizer is a packed column type, which offers superior performance over tray deodorizers.
Crown’s MaxEfficiency deodorizing system is more energy efficient and easier to service than single-vessel, all-in-one designs.
Crown’s Double Shell Packed Column (DSPC) deodorizer offers the strongest protection from air infiltration compared to traditional single-shell packed column designs. The DSPC houses the packing for free fatty acid (FFA) stripping in a column inside the deodorizer, enabling independent operation from the deodorizer’s retention section.
Each step of the MaxEfficiency deodorizing process is designed for the optimal performance of the system as a whole.
The deodorizer de-acidifies and deodorizes oil in physical refining and deodorizes oil in chemical refining.
Crown offers two distillate-scrubbing options: a high-efficiency design for a single distillate and a dual scrubber for concentrating recovered tocopherols. Several vacuum systems can be used—traditional and direct and indirect vacuum systems or chilled loop and ice-condensing vacuum systems.
- Highest deodorizing efficiency
- Lowest steam and fuel consumption
- Maximum protection of the oil and packed column
- Maximum vacuum on retention trays
- Minimal fouling of heat exchanger surfaces and packing
- Variable time in retention section
- Improved access for maintenance
- Double shell for vapor bypass, maximizing vacuum on retention trays and protecting packing
- Structured packing for stripping fatty acids and other volatiles from oil
- Plug-flow, steam-agitated retention trays with bypasses to vary the retention time
- Deaerator and post-deodorizer with structured packing to maximize air, moisture and volatile removal
- External heat exchangers to maximize energy recovery
- Independent vessels and external heat exchangers for easier and safer maintenance, economic upgrades and capacity increases
- No coils inside the deodorizer
- High-efficiency scrubber for minimal fatty matter carryover to the vacuum system
- Hermetic sealed pumps for minimum air leakage
- Steam-sealed manways on the deodorizer
