Description

Technical Field

[0001] This utility model relates to the field of lecithin preparation technology, specifically a traditional freeze-dried egg yolk lecithin production and preparation device. Background Technology

[0002] Egg yolk lecithin is a high-energy parenteral nutrition solution used in total intravenous nutrition. Therefore, a traditional freeze-dried egg yolk lecithin production and preparation apparatus is proposed here.

[0003] Currently, the conventional methods for preparing lecithin include the following processes:

[0004] Defatted egg yolk powder is extracted in a solvent such as ethanol to obtain a solution containing lecithin. The solution is then subjected to filtration, ultrafiltration, concentration and freeze-drying to obtain the product.

[0005] Obviously, the ability to effectively extract lecithin from defatted egg yolk powder is very important and crucial, as it directly affects production costs.

[0006] The current extraction is carried out in an extraction tank equipped with a stirring device. However, because the lecithin content in defatted egg yolk powder is low, generally only 35-45%, and defatted egg yolk powder forms a two-phase system when mixed with solvents such as ethanol, conventional stirred extraction tanks, even under heating conditions, are difficult to achieve high extraction efficiency, with an extraction yield of only 30-40%.

[0007] Many patents have improved the structure of the extraction tank in order to obtain higher extraction efficiency. For example, Chinese Patent Publication No. CN201969381U proposes a device for extracting phospholipids from defatted egg yolk powder with external circulation. After studying the existing technology and the above-mentioned patent, it was found that the extraction efficiency of the above-mentioned prior art still needs to be improved. Therefore, this utility model proposes a traditional freeze-dried egg yolk lecithin production and preparation device. Utility Model Content
