Decoloring hargil self-absorption system and use method thereof

Abstract

The invention relates to the field of decoloring and specifically relates to a decoloring hargil self-absorption system and a use method thereof. The decoloring hargil self-absorption system comprisesa decoloring tank and a pulping tank matched with the decoloring tank; a mixing device used for mixing hargil with oil is arranged in eacg of the decoloring tank and the pulping tank; a vacuum pipeline used for vacuumizing the interior of the decoloring tank is arranged on the decoloring tank; a pressure gauge and an adjusting valve are arranged on the decoloring tank; a self-absorption device for utilizing micro negative pressure to cause the self-absorption of hargil is arranged on the pulping tank. The specific use method thereof comprises the following steps: (1) pulping; (2) decoloring;(3) sealing; (4) collecting: adding hargil into the pulping tank, mixing hargil and oil till forming slurry, and accurately adding hargil according to the oil quantity. Compared with uneven hargil caused by the continuous decoloring device, the decoloring hargil self-absorption system can achieve uniform decoloring of hargil. Compared with powdered hargil, the pulped hargil is capable of reducingdust pollution in a use process, does not fly around and is capable of reducing the waste phenomenon.

Description

technical field [0001] The invention relates to the field of decolorization, in particular to a decolorization clay self-priming system and a method for using the same. Background technique [0002] In the decolorization process of rice bran oil, white clay is a commonly used decolorizing agent for grease, and sometimes an appropriate amount of activated carbon is added, but because the particles of white clay and activated carbon are small, a little carelessness will cause dust to fly, which is neither hygienic nor wasteful. , At the same time, it causes very serious dust pollution, which also poses a great threat to the physical and mental health of the staff who operate this step. How to solve this problem still needs to be studied. Contents of the invention [0003] In order to solve the above problems, the present invention proposes a decolorized clay self-priming system and its application method. [0004] A self-priming system for bleaching clay, comprising a decol...
