edible oil refining equipment technology process and method

Edible oil refining is a complicated and flexible work. It is necessary to select a suitable refining method according to the purpose of oil refining, taking into account the technical conditions and economic benefits. According to the operation characteristics and the selected raw materials, the oil refining methods can be roughly divided into mechanical method, chemical method and physical chemical method. According to the amount of cooking oil and the budget of customers, cooking oil refining equipment can also be divided into intermittent refining equipment, semi-continuous refining equipment and full-continuous refining equipment.

The significance of cooking oil refining equipment:

1. Enhance storage stability of oils and fats
2. Improve the flavor of oils and fats
3. Improve oil color.
4. Raw materials for deep processing of oils and fats.
 
The process of cooking oil refining equipment:
Extraction oil, degumming, deacidification, decolorization, deodorization, and refined oil.
 

Main stages and functions of cooking oil refining equipment:

• Degumming - we use hydration degumming. The basic principle of degumming oil by hydration is to use the hydrophilicity of colloidal impurities such as phospholipids to add a certain amount of electrolyte solution to the oil so that the colloidal impurities can absorb water and separate from the oil after coagulation.
• Deacidification - the existence of free fatty acids in crude oils will increase the difficulty of preservation of edible oils. The main purpose of deacidification is to remove free fatty acids from oils.
• Decolorization - commonly used adsorption decolorization of oil decolorization, removing pigment from vegetable oils;
• Deodorization - the use of high temperature and high vacuum distillation method to remove the unique flavor of the oil itself, taste and in the process of refining the flavor of other auxiliary equipment;

 

Refining effect of cooking oil refining equipment:

The oil treated by cooking oil refining equipment has transparent color, long-term storage without precipitation, no foam under the pot, no oil smoke, up to the national edible oil standards, and can be directly filled and sold.
 
Edible oil refining equipment:
Edible oil refining equipment is the crude oil (peanut oil, rapeseed oil, tea seed oil, soybean oil, sunflower seed oil, flax oil, walnut oil, sesame oil and other edible oils) through heating stirring for hydration degumming, deacidification, decolorization, deodorization.

Types of cooking oil refining equipment:

Batch refining equipment - 1-10 tons / day
Semi continuous refining equipment -- 10-30 tons / day
Continuous refining equipment -- 30-600 tons / day
