Description

Technical Field

[0001] This utility model belongs to the technical field of equipment for grain and oil processing, refining and degumming processes, specifically relating to a phosphoric acid tank used in vegetable oil refining workshops for adding, filtering and storing liquid phosphoric acid. Background Technology

[0002] Oils obtained from oilseeds through the leaching process are commonly known as crude oil. They contain a large number of oil-soluble compounds, with a high content of phospholipids. Because phospholipids significantly affect subsequent refining processes such as deacidification, decolorization, and deodorization, dephospholipid removal is typically the first step in oil refining. In production, phospholipids generally exist in a colloidal state; this process is often referred to as degumming.

[0003] Phospholipids exist in oil primarily in two states: hydrated phospholipids and non-hydrated phospholipids. Hydrated phospholipids are typically removed by adding a certain amount of soft water, while non-hydrated phospholipids need to be converted into hydrated phospholipids for removal. Adding an electrolyte solution to the oil alters the hydration level of the non-hydrated phospholipids, causing them to coagulate, allowing for the separation of the gums and oil using a centrifuge. Food-grade phosphoric acid is used as the electrolyte solution added to the oil to ensure effective degumming and the quality of subsequent processing steps.

[0004] Food-grade phosphoric acid is sold in drums and needs to be added to oils in specific proportions during production, thus requiring a phosphoric acid tank for liquid storage. Phosphoric acid is a strong acid with high corrosiveness; contact with skin, mucous membranes, and other tissues can cause significant harm. Utility Model Content
