Background technology
, it is necessary to turn into deodorization product oil by deodorization procedures, deodorization procedures are generally in deodorizing tower during vegetable oil refining
Middle completion, for being volatilized or being evaporated removing by the stink substance in vegetable oil.
Vegetable oil deodorized is a high temperature, high vacuum wet distillation process, not only to remove free fatty in grease
And the stink substance such as aldehyde, ketone, unsaturated hydrocarbon carbon compound, moreover it is possible to remove peroxide, oil plant grows, transported, it is improper to store
Go mouldy caused catabolite, small molecule PAH, residues of pesticides, while pyroprocess destroys partial pigment, allows its decomposition to go
Remove.Therefore grease deodorization is to remove stink, improve smoke point, improve the most key step of flavor, lifting edible oil quality.
Existing deodorizing system is mostly packed tower, plate tower combined column pattern, and top is packed tower, and bottom is plate tower, and plate tower is each
When the stripped vapor and stripping distillation of layer flow through top packing layer after collecting, producing vapour locking causes plate tower section vacuum to be deteriorated, no
Polymerisation easily occurs simultaneously for the removing beneficial to low component stink substance in oil, influences Vegetable Oil Quality.Deodorizing system at present
Above limitation result in deodorization Srteam Stripping effect it is bad, therefore use long-time high-temperature residence with reach at utmost remove stink thing
The purpose of matter, but the increase of content of trans fatty acids is brought, trans-fatty acid has very big endanger, increasingly to health
Paid attention to by people.On the other hand while removing stink substance, the beneficiating ingredient VE in vegetable oil is also with deodorization distillation one
With being carried over, follow-up deodorization distillate capturing device is that aliphatic acid trap fails effectively individually to reclaim VE and integrated profit
With.In addition existing deodorizing system is packed tower, the single integrated mode of plate column, and vegetable oil is completed entirely to be deodorized by setting process
Journey, for the characteristic of different oil plants, adaptability and the big heavy discount of modulability in production, reach identical finished product oil index input into
This increase.
