Abstract
The invention discloses a colza oil decoloring technology. The colza oil decoloring technology comprises the following operation steps: soft water and activated clay in equal proportion are fully mixed in a multi-effect reactor, the mixture and oil to be decolored enter a continuous decoloring tower to be subjected to a vac-sorb reaction for decoloring, wherein the decoloring temperature is 60 DEG C, the decoloring time is 20 minutes, and the decoloring pressure is 850 mbar., the decolored mixing oil enters a vane filter for filtering, and the filtered decolored oil is cooled in a decolored oil temporary storage tank. According to the method, the decoloring ability of wet method decoloring for pigment is obviously higher than that of dry process decoloring, appearance of grease can not be affected, and the decoloring effect is obviously improved.
Description
Technical field
The present invention relates to a kind of bleaching technique.
Background technology
Sweet three esters of main component of grease are colourless when liquid state, but common various greases are all with distinct colors, and this is because oil-containing quantity and the different pigment of kind in grease.Although most pigments are all nontoxic, can affect the outward appearance of grease.Therefore, in the time of producing high-grade oil and fat product, must be to the grease processing of decolouring.
The method of grease-decolor is a lot, in industrial production the most widespread use be adsorption decoloring method, in adsorption bleaching craft, the most conventional sorbent material is atlapulgite.Dry method decoloration process parameter: 90 ℃ of bleaching temperatures, bleaching time 35min, decolouring pressure 70mbar.
Summary of the invention
In order to have solved the problems of the prior art, the invention provides a kind of bleaching technique, wet method decolouring is obviously better than dry method decolouring to the ability that removes of pigment, can not affect the outward appearance of grease, and decolorizing effect obviously improves.
Technical scheme of the present invention is as follows:
A kind of bleaching technique, include following operation steps, first soft water after fully mixing, multiple-effect reactor is entered together with treating bleached oil again to continous way bleaching tower vacuum suck reaction decolouring by equal proportion with atlapulgite, 60 ℃ of bleaching temperatures, bleaching time 20min, decolouring pressure 850mbar., decolouring mixing oil enters vane type filtration machine and filters, and filters rear decoloring oil cooling to the temporary tank of bleached oil.
Wet method decolouring of the present invention is obviously better than dry method decolouring to the ability that removes of pigment, can not affect the outward appearance of grease, and decolorizing effect obviously improves.
The present invention and conventional dry decoloration process contrast, specific as follows:
Embodiment
A kind of bleaching technique, include following operation steps, first soft water after fully mixing, multiple-effect reactor is entered together with treating bleached oil again to continous way bleaching tower vacuum suck reaction decolouring by equal proportion with atlapulgite, 60 ℃ of bleaching temperatures, bleaching time 20min, decolouring pressure 850mbar., decolouring mixing oil enters vane type filtration machine and filters, and filters rear decoloring oil cooling to the temporary tank of bleached oil.
Claims (1)
1. a bleaching technique, include following operation steps, it is characterized in that: first soft water is entered after multiple-effect reactor fully mixes together with treating bleached oil again to continous way bleaching tower vacuum suck reaction decolouring by equal proportion with atlapulgite, 60 ℃ of bleaching temperatures, bleaching time 20min, decolouring pressure 850mbar., decolouring mixing oil enters vane type filtration machine and filters, and filters rear decoloring oil cooling to the temporary tank of bleached oil.
