Embodiment Construction

[0007] The operation process of the oil refining equipment: the crude oil is pumped into the water washing pot 4 or 5 with the pump 1, and phosphoric acid and soft water are added for degumming and chelating operations. When the oil and the oil foot are obviously separated and sink rapidly, stop stirring, let it stand for a certain period of time, release the oil foot, and then suck the clear oil to the decolorization tank 6. The oil foot is put into the oil foot barrel 38 from the bottom emptying pipe. When the oil foot contains a lot of oil, stop draining the oil foot. The oil foot is pumped into the oil foot tank by the pump 31, and mixed with the remaining oil in the washing tank into the next tank Continue to wash and chelate. The clear oil transferred in the water washing tank is removed to the decolorization tank 6 for adsorption and decolorization, and the vacuum water ring pump 8 passes through the liquid foam trap 7, so that the decolorization tank 6 reaches a vacuum...

Abstract

According to a production technique provided by the invention, medium-temperature soft water washing is adopted and phosphoric acid or citric acid is added to chelate heavy metal ions in the process, so that possibility of grease oxidation is reduced; to ensure the quality of edible oil, the dewatering and the decoloration procedures are carried out in a vacuum environment; the stability of the grease is ensured by adding a certain amount of citric acid in the deacidification and deodorization procedures, and the grease is high in yield and good in quality because of physical deacidification and deodorization in high vacuum; automatic temperature adjustment is adopted, so that the product quality is ensured; vacuum pipelines are arranged, so that the vacuum environment is ensured; and the oil circulation period is shortened by adopting a continuous or semi-continuous production mode.

Description

Technical field: [0001] The production technology involved in the invention is widely applicable to various oil product refining processes in the animal edible oil industry. Background technique: [0002] At present, most of the small and medium-sized oil companies in the market use intermittent processes in the animal oil refining process; the equipment required for this process includes: refining pots, water washing pots, decolorizing pots, deodorizing pots, etc. The operation is complicated and the cost is high; the production cycle long, and the quality of the oil cannot be guaranteed. Invention content: [0003] The production process involved in this project is semi-continuous and continuous, including water washing, decolorization, deacidification, and deodorization production lines. The decolorization pot, deacidification, and deodorization are all operated under negative pressure, and the functions of deacidification and deodorization are integrated; , Decoloriza...
