A technical method for reducing the viscosity of rapeseed oil feet by using ultrasonic waves

Abstract

The invention relates to a technical method for reducing the viscosity of rapeseed oil bottoms by using ultrasonic waves, comprising the following steps: (1) adding sodium hypochlorite to the rapeseed oil bottoms, adding glacial acetic acid dropwise to adjust the pH value to 4-5; (2) adding Insert the ultrasonic probe into the reaction material for ultrasonic treatment; (3) After taking out the ultrasonic probe, place the reaction vessel in a water bath to heat, and react at a constant temperature; (4) After the reaction is completed, add water to wash for 2 to 4 times, and take the upper layer That is the finished product. The invention effectively reduces the viscosity of the rapeseed oil bottom by modifying the rapeseed oil bottom, expands the way of comprehensive development and utilization of the rapeseed oil bottom, not only can improve the production efficiency of the enterprise, but also reduces the pollution to the environment . At the same time, ultrasonic auxiliary technology is used in the process of reducing viscosity, which more effectively shortens the reaction time, improves production efficiency and processing effect, has the advantages of convenient use, low cost, and low investment, and is suitable for large and medium-sized oil processing enterprises.

Description

technical field [0001] The invention relates to a method for reducing the viscosity of rapeseed oil bottoms, in particular to a technical method for reducing the viscosity of rapeseed oil bottoms by using ultrasonic waves. Background technique [0002] Rapeseed oil foot is a by-product of hydration and degumming of crude rapeseed oil. In the process of producing rapeseed oil by leaching, the degumming process is one of the key steps in its refining. A certain amount of water is added to the rapeseed oil degumming process, and the phospholipids in the rapeseed oil foot absorb water and swell to form a colloid, which also contains neutral oil and other impurities. After centrifugation, the oil foot can be obtained. my country is a big producer of rapeseed edible oil, but due to the high viscosity of rapeseed oil bottoms, the comprehensive development and utilization of rapeseed oil bottoms are greatly restricted. Usually, the method of salting out is used for the hydration of...

Problems solved by technology

my country is a big producer of rapeseed edible oil, but due to the high viscosity of rapeseed oil bottoms, the comprehensive development and utilization of rapeseed oil bottoms are greatly restricted. Usually, the method of salting out is used for the hydration of rapeseed oil bottoms. Dispose of as waste after

First, oily feet contain useful substances such as phospholipids with high nutritional value. These resources are wasted in vain, resulting in a waste of resources. Second, oily feet are prone to rancidity and odor, which will also cause certain pollution to the environment.
