Problems solved by technology

[0002] The refining process of vegetable oil includes deacidification and deodorization processes. Most of the existing deacidification and deodorization have the problems of energy consumption, water consumption, and waste liquid. Moreover, the time and temperature of the deacidification process and deodorization process are poorly operable and cannot be controlled. The content of plasticizers, glycidyl esters, and trans fatty acids in oils cannot retain the content of sterols and vitamin E in corn oil

Abstract

The invention discloses a vegetable oil deodorizing and deacidifying refining device and process, and belongs to the technical field of vegetable oil refining. The problems that in the prior art, theflexibility is poor, the deacidification and deodorization temperature and time cannot be controlled, the refining efficiency is low, and the effect is poor are solved. The vegetable oil deodorizing,deacidifying and refining device comprises a deodorizing tower and a deacidifying tower, and further comprises a deaerator and a falling film type heat exchanger, wherein the deaerator, the falling film type heat exchanger, the deodorizing tower and the deacidifying tower are sequentially connected through pipelines, and the deacidifying tower is connected with a finished oil temporary storage tank through a pipeline; a filter I is arranged between the deaerator and the falling film type heat exchanger; a heater I is arranged between the falling film type heat exchanger and a deodorization tower, a heater II is arranged between the deodorization tower and the deacidifying tower, upper gas outlets of the falling film type heat exchanger, the deodorization tower and the deacidification towerare respectively connected with a fatty acid trapping tower, and a lower outlet of the fatty acid trapping tower is connected with a fatty acid temporary storage tank. The vegetable oil deodorizing and deacidifying refining device and process can be used for refining vegetable oil.

Description

technical field [0001] The invention relates to a vegetable oil deodorization and deacidification refining device and process, belonging to the technical field of vegetable oil refining. Background technique [0002] The refining process of vegetable oil includes deacidification and deodorization processes.
