Embodiment Construction

[0018] A decolorizing agent for the refining of vegetable oils by adding modified activated Imonite mixed layer clay, prepared from the following parts by weight (kg) of raw materials: Imonite mixed layer clay ore 100, hydrochloric acid 30 with a concentration of 6wt%, hexadecane Trimethylammonium bromide 25, appropriate amount of deionized water, macroporous adsorption resin HP2MGL34, chitosan 10, 2wt% acetic acid 100, graphene oxide 10, appropriate amount of ethylene glycol, sodium acetate 62, hexahydrate Ferric chloride 16.

[0019] The decolorizing agent for the refining of vegetable oil and adding organically modified activated Imon mixed layer clay is prepared by the following specific steps:

[0020] (1) Firstly, crush the Imon mixed layer clay ore to particles with an average particle size of 15 mesh, then dry it in an oven at a temperature of 200 ℃, and then pulverize it into a powder of 200 mesh for use; Methyl ammonium bromide was dissolved in 40 times the amount of dei...

Abstract

The invention discloses a modified activated illite smectite mixed layer clay-added decoloring agent used for refining vegetable oil, the modified activated illite smectite mixed layer clay-added decoloring agent used for refining the vegetable oil is characterized by comprising the following raw materials by weight: 100-110 parts of illite smectite mixed layer clay raw ore, 30-33 parts of hydrochloric acid, 25-27 parts of cetyl trimethyl ammonium bromide, a proper amount of deionized water, 34-37 parts of macroporous adsorption resin, 10-11.5 parts of chitosan, 100-110 parts of acetic acid with the concentration of 2wt%, 10-12 parts of graphene oxide, a proper amount of ethylene glycol, 62-65 parts of sodium acetate and 16-18 parts of ferric trichloride hexahydrate. The decoloring agent is used for refining the vegetable oil, can not only remove pigments in the vegetable oil, and also can absorb residual metal ions, toxins, residue gum and other substances in the vegetable oil, the production process is easy to control, and decoloring effects are excellent.

Description

Technical field [0001] The invention relates to the technical field of oil decolorization, in particular to a decolorizing agent used for refining vegetable oils by adding modified activated Imon mixed layer clay. Background technique [0002] Oil decolorization is a very important step in the process of oil refining, which can improve the appearance of oil products. The adsorption method is commonly used in industry for decolorization. The adsorption decolorization method uses the difference in molecular attraction between the adsorbent and the pigment material and the product to combine the pigment molecules with the adsorbent and separate them from the oil, thereby removing the pigment in the oil. In particular, the decolorization process of vegetable oil can not only remove the pigment and improve the color of the oil, but also remove the trace metal ions, residual gums and some odorous substances brought into the vegetable oil during the oil refining process, thereby making ...
