Embodiment 1

[0025] A kind of composite activated carbon decolorizing agent, it is made up of following material component and weight percentage:

[0026] Coconut shell activated carbon 50%, wood activated carbon 30%, resin 10%, activated clay 5%, diatomaceous earth 5%.

[0027] Fully mix the above-mentioned powdered material raw materials with good proportions, carry out preliminary screening (for example, according to the standard of 6-50 mesh), and then dry with hot air until the moisture content is 10%-25%, kneading, and then carry out in the rotary kiln Activation, followed by recovery and rinsing, and finally dehydration and drying, ball milling, sorting, inspection and packaging to obtain the final product. The finished product is used to decolorize brown sugar into white sugar. Compared with independent activated carbon, it has stronger adsorption, high decolorization efficiency, and better color of white sugar. Moreover, compared with conventional activated carbon of equal quality...

Embodiment 2

[0035] A kind of composite activated carbon decolorizing agent, it is made up of following material component and weight percentage:

[0036] Coconut shell activated carbon 55%, wood activated carbon 25%, resin 10%, activated clay 5%, diatomaceous earth 5%.

[0037] Fully mix the above-mentioned powdered material raw materials with good proportions, carry out preliminary screening (for example, according to the standard of 10-60 mesh), and then dry with hot air until the moisture content is 10%-25%, kneading, and then carry out kneading in a rotary kiln Activation, followed by recovery and rinsing, and finally dehydration and drying, ball milling, sorting, inspection and packaging to obtain the final product. The finished product is applied to the decolorization of monosodium glutamate. Compared with independent activated carbon, it has stronger adsorption, high decolorization efficiency, good color of the prepared white sugar, fast filtration speed and high light transmittanc...

Embodiment 3

[0039] A kind of composite activated carbon decolorizing agent, it is made up of following material component and weight percentage:

[0040] Coconut shell activated carbon 50%, wood activated carbon 25%, resin 15%, activated clay 5%, diatomaceous earth 5%.

[0041] Fully mix the above-mentioned powdered material raw materials with good proportions, carry out preliminary screening (for example, according to the standard of 20-70 mesh), and then dry with hot air until the moisture content is 10%-25%, kneading, and then carry out kneading in a rotary kiln Activation, followed by recovery and rinsing, and finally dehydration and drying, ball milling, sorting, inspection and packaging to obtain the final product. The finished product is applied to beer filtration, and compared with independent activated carbon, it has stronger adsorption, high decolorization efficiency, and the fineness of the prepared liquor is good.

Abstract

The invention discloses a compound active carbon decolorizing agent, which is prepared from, by weight, 40%-55% of cocoanut active charcoal, 20%-30% of wooden activated carbon, 8%-15% of resin, 4%-6% of activated clay, and 4%-6% of diatomite. The compound active carbon decolorizing agent can solve the problems which the prior active carbon decolorizing agent can not resolve well such as decoloration and deodorization, color reversion and purification during the process of food fermentation production, comprehensively adopting the advantages of all the materials, avoiding all the shortcomings. Through recombination and matching, the fine compound active carbon decolorizing agent is formed, which has the advantages of high capacity for decoloration and deodorization, less usage every time, fast filtration speed, fine transparency of mother liquor, strong ability to remove peculiar smell, strong capacity for resisting color reversion, non-toxic, tastelessness, and odorlessness, and is widely applicable to fields such as decolorizing of aginomoto, fermentation, sugaring and the like.

Description

technical field [0001] The invention relates to a decolorizing agent, in particular to a composite active decolorizing agent. Background technique [0002] Activated carbon is a kind of black porous solid carbon, which is usually produced by crushing, molding or carbonizing and activating wood products with uniform wood particles. The main component is carbon, and contains a small amount of oxygen, hydrogen, sulfur, nitrogen, chlorine and other elements. The specific surface area of ​​ordinary activated carbon is 500~1700m 2 / g room. As a high-performance adsorbent and catalyst, it is widely used in various fields of industry, agriculture, national defense, science and technology and people's life, and has become an indispensable important substance in the national economy. About 59.8% of my country's powdered activated carbon is used in medicine, about 26.6% in the sugar industry, about 13.6% in food and other aspects; about 51.2% of granular activated carbon is used in ...
