Problems solved by technology

[0003] The purpose of the present invention is to provide a kind of oil filter impurity removal process with high colloidal content, solve the existing vegetable oil crude oil impurity removal by sedimentation, filtration, centrifugation and other methods, and use settling tanks, decanter centrifuges, blade filters, Equipment such as plate and frame filters cannot meet the requirements of filtering impurities such as corn crude oil with high colloidal content. The filtering effect is poor, the oil loss is large, and the production cost is high, which is not conducive to improving economic benefits. The invention provides a design Reasonable and compact filter and impurity removal technology with good impurity removal effect, easy operation and high comprehensive benefit

Embodiment Construction

[0008] Further illustrate the present invention in conjunction with accompanying drawing and embodiment, as shown in Figure 1, the technological process of the present invention is that vegetable oil crude oil enters raw material oil heater 2 heating from oil supply pipeline 5, after being heated to 40-50 ℃, is transported by oil pipeline 8 Enter the program-controlled membrane filter press 1, the filtered clean oil flows out through the oil pipeline 9, and the filtered residue cake is blown by the compressed air input from the pipeline 7 and squeezed dry from the tympanic membrane, and then falls off the filter cloth, and is removed by the opened filter plate. The gap falls into the slag cake collection tank 3, and then it is conveyed by the slag cake conveying auger 4 integrated with it, and is packed and loaded through the discharge port 10.

[0009] The program-controlled membrane filter press 1 is an existing product, which is generally used in the fields of starch process...

Abstract

The invention relates to a filtering and impurity removing technology for oil with high colloid content, belonging to the technical field of vegetable oil refining. The invention relates to a depositing, filtering and centrifugalizing technology which is adopted by the prior base oil impurity removal and is suitable for the filtration and the impurity removal of oil with high colloid content and the improvement of an adopted corresponding device. Crude oil is heated and then is filtered by a program-controlled film type pressure filter technically. The invention reduces procedures, increases the oil yield by filtering and impurity removing, has reasonable and compact design, good impurity removing effect, convenient operation and high comprehensive benefit, is suitable for filtering and removing impurities of various kinds of vegetable oil and especially has advantages for removing impurities of oil with high colloid content, such as corn base oil in base oil.

Description

technical field [0001] The invention relates to a filter and impurity removal process for oil with high colloid content, and belongs to the technical field of food oil refining. Background technique [0002] Vegetable oil and crude oil are generally removed by sedimentation, filtration, centrifugation and other methods. The corresponding processing equipment mainly includes: settling tank with slag extractor, decanter centrifuge, leaf filter, plate and frame filter, etc. Settling tanks are used to separate insoluble impurities, but the existing settling tanks have disadvantages such as long settling time, high oil content in the slag, and large equipment footprint, so they can only be used for coarse filtration of raw oil; it is generally believed that the centrifugal separation method has the advantages of It has the advantages of high separation efficiency, low oil content in the filter residue, continuous production, and large processing capacity. However, it is found in ...
