Embodiment Construction

[0012] Further illustrate the present invention in conjunction with accompanying drawing and embodiment, as shown in Figure 1, in the present invention, the outlet of the acidification tempering tank 5 in the long-term mixing and short-mixing process is equipped with an overflow outlet pipeline 5 ", through the installation on the pipeline Several sets of valves with different heights are used to adjust the time of acidification and tempering of the raw material oil. An overflow outlet pipeline 8" is installed at the outlet of the alkali delay tank 8, and several sets of valves with different heights installed on the pipeline are used to adjust the alkali neutralization The reaction time, through the above process configuration, realizes the mutual switching of long-mixing / short-mixing in the alkali refining process.

[0013] As shown in Figure 1, any one of the soap-removing centrifuge 11 and the soap-removing centrifuge 13 can form an alkali refining process of soap removal a...

Abstract

The invention relates to an alkali-refining process of vegetable oil with high content of unsaturated acid, belonging to the technical field of the vegetable oil refining. Adopting the long-time mixing / short-time mixing (two-time soapstock removing) and one-time washing or adopting long-time mixing / short-time mixing (one-time soapstock removing) and two-time washing, the invention optimally combines together the prior various alkali-refining processes. The invention adopts three centrifugal machines, wherein the two-time soapstock removing is carried out by the No. 1 centrifugal machine and the No. 2 centrifugal machine, and the washing is carried out by the No. 3 centrifugal machine; and the one-time soapstock removing is carried out by the No. 1 centrifugal machine, and the two-time washing is carried out by the No. 2 centrifugal machine and the No. 3 centrifugal machine. The invention overcomes the defect that the prior various alkali-refining processes can not meet the refining ofpart of oil with high content of unsaturated acid, such as the corn oil, and the invention has good alkali-refining effect and high comprehensive benefit, is beneficial to the improvement of the product quality and the economic benefit, can realize alkali-refining process by one-time soapstock removing and one-time washing through controlling a sluice valve which is arranged in a pipe and has wideapplication range and high economic benefit.

Description

technical field [0001] The invention relates to a vegetable oil alkali refining process with high unsaturated acid content, belonging to the technical field of vegetable oil refining. Background technique [0002] The typical alkali refining process of existing vegetable oil is a one-time desoaping and one-time washing process. This process is divided into a "long-mixing" alkali refining process and a "short-mixing" alkali refining process according to the length of the neutralization reaction. The above-mentioned alkali refining process It is only suitable for crude oil with good quality. If the original quality of vegetable oil is very poor, two alkali refining processes (twice soap removal) + water washing process or one alkali refining process (one soap removal) + two water washing processes are required . [0003] For oils whose crude oil quality often changes, such as corn oil, none of the above processes can meet the needs of alkali refining. Contents of the invent...
