Embodiment Construction

[0022] As shown in Figure 1, 1000 kg of Hang Jin 2 # Crush the soil into 20 meshes, soak and mix with 800 kg of hydrochloric acid solution and boil for 60 minutes, and keep stirring, absorb waste acid gas with ammonia water, filter to obtain filter cake, collect the filtrate, wash the filter cake with water until nearly neutral, After the washed filter cake is naturally air-dried, it is sent into a high-temperature furnace and roasted at 300° C. for 2 hours, then cooled and pulverized into 250 meshes to obtain 700 kilograms of edible oil decolorizer. The above-mentioned absorption liquid and filtrate of absorbing waste acid gas with ammonia water are combined with the first and second washing water for washing the filter cake, neutralized with ammonia water precipitation to a pH value of 8, and filtered to obtain Fe(OH) 3 The filter cake is precipitated, and then washed with water, dried at 105°C, and then roasted at 490°C to obtain 57 kg of iron red, and the filtrate is evapo...

Abstract

The present invention discloses a production method of decolouring agent for edible oil. Said method is characterized by that it adopts the following steps: pulverizing Hangjin No.2 soil, adding hydrochloric acid and slightly boiling, filtering to obtain filter cake, collecting filtrate, washing filter cake with water to neutrality, natural drying cleaned filter care, roasting in high-temp. furnace, cooling and pulverizing to above 250 meshes so as to obtain the invented decolouring agent for edible oil.

Description

technical field [0001] The invention relates to a production method of an edible oil decolorant, in particular to a method for producing the edible oil decolorant by using non-metallic clay ore as a raw material. Background technique [0002] At present, the decolorizing agent for edible vegetable oil refining used at home and abroad is generally activated clay. Activated white clay is made of natural clay as raw material, and then produced by various processes such as heating and roasting. This type of activated clay is more expensive. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a production method of an edible oil decolorizer. [0004] The technical problem of the present invention is solved by following scheme: the production method of edible oil decolorizer, comprises heat treatment with acid, roasting activation process, is characterized in that Hang Jin 2 # The soil is crushed into more than 20 meshe...
