Evaporation device for condensation, freezing and deodorization of grease

Abstract

The invention relates to an evaporating device for condensing, freezing and deodorizing oil and fat. The evaporating device comprises at least two evaporators (1); air inlets (101) are formed in the lower parts of the two evaporators (1) and are connected with an air outlet of a system to be deodorized; air outlets (102) are formed in the upper parts of the two evaporators (1) and are connected with an air inlet of a roots liquid ring vacuum unit (13) through pipelines; a cooling water outlet (103) and a cooling water inlet (104) are respectively formed in the top and bottom of each evaporator (1); and the cooling water outlets (103) and the cooling water inlets (104) are respectively connected with an inlet and an outlet of a condensing unit. By using the evaporating device, the heat exchange effects of the evaporators can be improved, the work efficiency of the whole vacuum equipment can be increased, the energy consumption can be reduced, and the enterprise cost can be reduced.

Description

technical field [0001] The invention relates to an evaporator, in particular to an evaporating device for condensing, freezing and deodorizing grease. 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 tower through the steam jet pump unit and th...

AI Technical Summary

Problems solved by technology

[0004] 1. The balance of the vacuum degree cannot be ensured between the two evaporators, and the vacuum degree will fluctuate and affect when switching, which will affect the quality of the produced products; the two evaporators will cause vibration when they are turned on and off, reducing work efficiency and use life, increase production and maintenance costs;

[0005] 2. In the normal production process, the tube from the inside of the evaporator will be blocked due to freezing. After working for a period of time, the evaporator needs to be closed for manual cleaning, which greatly reduces the work efficiency and increases the maintenance cost and workload.
