Edible oil condensation and freezing deodorization vacuum equipment

Abstract

The invention relates to a vacuum equipment for condensing, freezing and deodorizing edible oil, which is characterized in that it includes an evaporation unit, a condensation unit and a Roots liquid ring vacuum unit (14), and the evaporation unit includes at least two evaporators (1). An air inlet (101) is provided at the lower part of the two evaporators (1), and the air inlet (101) is connected to the air outlet of the system that needs to be deodorized. There is an air outlet (102), which is connected to the air inlet of the Roots liquid ring vacuum unit (13) through a pipeline, and a cooling water outlet (103) and a cooling water outlet (103) are opened on the top and bottom of the evaporator (1) respectively. The inlet (104), the cooling water outlet (103) and the cooling water inlet (104) are respectively connected with the inlet and outlet of the condensing unit. The invention can improve the heat exchange effect of the evaporator and the working efficiency of the whole vacuum equipment, reduce energy consumption and save enterprise cost.

Description

technical field [0001] The invention relates to a vacuum deodorization equipment, in particular to a vacuum deodorization equipment used for condensation and freezing of edible oils and fats. Background technique [0002] Edible oils and fats contain a lot of harmful substances before refining and deodorization treatment, such as: fatty acids, aldehydes, ketones, glycerides, etc., as well as process odors produced in the oil production process, such as burnt smell, solvent smell, hydrogenation smell, etc. . The edible oil deodorization process is to remove these harmful substances in the edible oil in the rectification tower by using the different physical properties of various materials under vacuum conditions, and use the vacuum low-pressure distillation method to remove them, so that we can obtain safe edible oil products. [0003] The traditional edible oil deodorization vacuum equipment directly extracts the harmful substances in the edible oil in the rectification ...

AI Technical Summary

Problems solved by technology

[0004] 1. The cooling water in the cooling water device is used as the refrigerant in the condenser, and it is not recycled in the whole process. The deodorization process needs to consume a large amount of high-temperature water vapor and a large amount of cooling water, which increases the cost of the enterprise;

[0005] 2. During the process of deodorizing edible oil, the condenser will freeze and solidify due to the sudden drop in temperature, and the pipe side and sewage outlet in the evaporator will be blocked due to freezing, and the normal operation of the whole set of equipment needs to be stopped for processing. Greatly affected work efficiency
