Description

A kind of oils and fats multi-stage absorption decolouring impurity removing equipment of continuous high-efficient

Technical field

This utility model belongs to grease processing technology field, is specifically related to a kind of continuous adsorption bleaching for polished fat Impurity removing equipment.

Background technology

Oils and fats, as one of the three nutritious elements of needed by human body, is that people absorb energy and other peculiar nutrition from diet The important sources of material.Meanwhile, along with aviation bio-fuel technology and other grease deep processing technology (fatty acid, plasticizer, alkene Hydrocarbon) development and application, Jatropha curcus, aleurite montana etc. " unedible oil fat " resource also becomes preparation aviation bio-fuel and chemical products Important source material.

It is known that the component of more than 95% is triglyceride in oils and fats, additionally, there may be peptized impurities (phospholipid, Saccharide, protein etc.), oil-soluble impurities (fatty acid, pigment, sterol etc.) and toxic ingredient (flavacin, polycyclic aromatic hydrocarbon etc.), These components not only affect safe storage and the edibility of oils and fats, and give in oils and fats deep processing such as biofuel production process Consersion unit, catalyst and product quality cause significant negative impact.Therefore, no matter which kind of oil resource, need according to not Same requirement and purposes, remove impurity unwanted, harmful from oils and fats.

Oil and fat refining mainly includes the process such as precipitation, degumming, deacidification, decolouring, deodorize and dewaxing (being commonly called as " six take off "), Wherein decolouring is the key operation together in oil and fat refining process.Grease-decolor method has adsorption bleaching, adds heat decoloring, oxidation Decolouring, chemical reagent decolouring etc., and only adsorption decoloring method is most widely used in current commercial production.Adsorption bleaching is just It is under conditions of temperature 80 DEG C～120 DEG C, time 15min～30min and evacuation, naturally occurring color in removing oils and fats Element, the most taller effect ground removes the heavy metal of trace, phospholipid, polycyclic aromatic hydrocarbon, pesticide residues, aflatoxin and in oils and fats A little materials frowzy, make every effort to farthest improve refined oil quality under lowest loss.
