White oil production line

Abstract

The invention discloses a white oil production line. The white oil production line comprises a filtering storage tank and a hydrogenation reaction vessel; the filtering storage tank comprises a filtering storage tank body (21), a double-layer tapered filter screen (22), a filter screen support (23), and a filter screen lifting device; the top of the filtering storage tank body (21) is provided with an oil inlet, and the bottom is provided with an oil outlet; a hollow guide rod (24) is vertically arranged in the filtering storage tank body (21); the rod wall of the hollow guide rod is provided with a pair of slot holes symmetrically; and the hollow guide rod (4) is sleeved with a telescopic pipe (25). The advantages are that: structure design is reasonable; slow filtering of white oil can be realized in storage process; filtering is fine; filtering in applications of white oil is avoided; working efficiency is increased; the adding amount of a catalyst is controlled automatically and accurately using a flow valve; the catalyst is added in a manner of uniform distribution on the top, so that full contact of the catalyst with tail oil and hydrogen is realized, and tail oil reaction fission process is accelerated.

Description

technical field [0001] The invention relates to the technical field of white oil production, in particular to a white oil production line. Background technique [0002] Shortening, the scientific name is white oil, because it looks white and looks like lard. Ghee is one of the special fats in the food industry. It has a certain plasticity or consistency, and is used as an ingredient for pastry, surface spraying or demoulding. It can be used to crisp or soften baked food, prevent protein and carbohydrates from becoming hard and lumpy during processing, and improve the taste. [0003] At present, edible white oil needs to be filtered when it is used in the field of food and medicine. The traditional filtration is to output the white oil from the storage tank and use it after filtering. Fine filtration takes a long time and low efficiency, which affects production efficiency; the production of edible white oil is generally produced by a one-stage hydrogenation process, and t...

[0003] At present, edible white oil needs to be filtered when it is used in the field of food and medicine. The traditional filtration is to output the white oil from the storage tank and use it after filtering. Fine filtration takes a long time and low efficiency, which affects production efficiency; the production of edible white oil is generally produced by a one-stage hydrogenation process, and the one-stage hydrogenation process uses hydrocracking tail oil or SSOT tail oil as raw material after solvent dewaxing. Using reduced metal catalysts to hydrogenate under high pressure, the product can reach food grade. At present, the addition of catalysts in existing production lines is usually manually weighed and added directly through the opening of the reaction tank. This method of adding catalysts is not necessary. It is conducive to the contact of the catalyst with tail oil and hydrogen, and is not conducive to the overall sealing design, which will slow down the reaction process, slow down the beat of the production line, and increase production costs
