Description

Technical Field

[0001] The present application relates to the technical field of oil processing equipment, and in particular to a device for reducing the acid value of animal oils and fats. Background Art

[0002] During processing, animal fats and oils are prone to rancidity due to the effects of lipase and storage conditions, resulting in a high acid value, which directly affects the quality and quality of the fats and oils. To ensure the quality of the fats and oils, reducing the acid value is a key task in animal fat processing. In existing technologies, the acid value of animal fats and oils is typically reduced through physical or chemical methods to meet relevant product quality and safety standards.

[0003] In order to reduce the acid value of animal fats, existing technical means mainly include the following: First, physical heating is used to evaporate and remove part of the free fatty acids in the fats by high temperature, but this method consumes a lot of energy and may damage the nutrients in the fats. Second, rancid fats are neutralized with alkali solution. By adding an appropriate amount of alkali solution to neutralize the free fatty acids in the fats, the acid value is reduced. This method is relatively mature and widely used. Third, adsorbent adsorption is used to adsorb the free fatty acids in the fats using adsorbents such as activated carbon, thereby achieving the purpose of reducing the acid value. However, this method has problems such as high adsorbent consumption and difficulty in regeneration.

[0004] Although the existing method of reducing the acid value of animal fats through alkali neutralization reaction can effectively reduce the acid value, in actual operation, uneven mixing of alkali and fat may lead to insufficient neutralization reaction, thereby affecting the acid value reduction effect of the fat.
