A rapeseed oil deodorization distillation device

Through the design of liquid distributor and multi-stage steam inlet pipe, rapeseed oil is dispersed into a thin layer in the deodorization tank, and steam contacts in the opposite direction. Combined with a vacuum pump to maintain a low-pressure environment, the problem of uneven contact between steam and oil is solved, the deodorization efficiency is improved and the steam consumption is reduced.

AI Technical Summary

Technical Problem

In existing rapeseed oil deodorization distillation equipment, uneven contact between steam and oil leads to low deodorization efficiency and increased steam consumption.

Method used

The design employs a liquid distributor and a multi-stage steam inlet pipe. The liquid distributor disperses the rapeseed oil into a thin layer, while the steam comes into contact with the jacket and the internal inlet pipe in reverse. Combined with a vacuum pump, a low-pressure environment is maintained, which promotes the escape of volatile substances.

Benefits of technology

This technology achieves efficient contact between steam and rapeseed oil, improves deodorization effect and reduces steam consumption, and solves the problem of low deodorization efficiency caused by uneven steam distribution in traditional devices.
