Animal grease refining process

Abstract

The invention provides an animal grease refining process. The animal grease refining process comprises the following steps: conveying crude oil into an oil refining container, stirring at a rotation speed of 55r / min-65r / min, and simultaneously heating to 60-65 DEG C; adding salt water into the oil refining container; decreasing the rotation speed, and stirring at a rotation speed of 25r / min-35r / min; when colloidal particles are flocculated to an obvious separation state, stopping stirring, standing for 2.5-4 hours, separating, and carrying out degumming; adding hot soft water into the oil refining container, simultaneously stirring, standing for precipitation, separating to remove residual nigre, and introducing the grease into an oil storage tank; conveying the grease in the oil storage tank to a dryer for drying; carrying out decolorization for 20 minutes; filtering the decolorized grease; carrying out self-circulation on a deodorization tower for 30 minutes, when the temperature ofoil in the deodorization tower is increased to 230-250 DEG C, carrying out sampling and examination, after the examination is qualified, setting an oil discharging temperature, and outputting the refined animal grease. According to the technical scheme provided by the invention, the quality of the refined animal grease is improved, the production efficiency is improved, the energy resource is saved, and the cost is lowered.

Description

technical field [0001] The invention relates to the technical field of oil refining technology, in particular to an animal fat refining technology. Background technique [0002] Oil refining refers to the removal of impurities, peculiar smell, and color in oil (crude oil). In related technologies, on the one hand, the work efficiency in decolorization and deodorization of animal oil is relatively low, and the stability of processing quality is poor. , On the other hand, the degumming effect is poor, the efficiency is low, and it is difficult to meet the needs of actual production and use. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related art. [0004] Therefore, an object of the present invention is to provide a kind of tallow refining process. [0005] In order to achieve the above object, the technical solution of the present invention provides a kind of animal oil refining...
