Supercritical CO: date kernel oil extraction (SCDE), as a new "green" capture separation technology, it has many advantages such as high extraction efficiency, low operating temperature, simple process, no organic solvent residue in the product, and has been widely used in food, fragrance and medicine fields L5.6J. In this experiment, the separation of flavonoids from jujube stone was studied with jujube stone as the material, with a view to the comprehensive processing and utilization of jujube and the extraction from waste plants.
The fat content of gray jujube stone is 0.408%, so the content is less, so it is unnecessary to degrease when extracting flavonoids.
The related production flow of date or jujube kernel.
Step 1. Date seed cleaning and drying machine. It will clean and dry the date seed material.
Step 2. Date seed grinder machine, it can be used for crushing and shredding date seed into 1-50mm size mesh powder.
Step 3. Date seed oil extraction machine. After date seed grinding machine, there’s large quantity date kernel powder will be entered into extraction and separation machine for date oil.
According to the products request, there’s refined equipment for customer choice.
The supercritical CO fluid extraction method is a good technique for the separation of flavonoids from jujube seeds kernel with simple operation, high extraction rate, good preservation of active ingredients and high quality. When the extraction pressure is 30MPa, the extraction temperature is 50℃, the extraction time is 120min, 75% ethanol is used as the entrained agent, and the dosage is 600mE(3mL/)g) the best effect, the extraction rate of flavonoids in jujube pits is1.6665%.
Tigers machinery factory will provide complete system for making jujube kernel oil, the main equipment we provided includes date seeds/jujube kernel seed cleaner and dryer, date seed grinding machine in grinders, automatic date seed oil extraction machine and so on. Welcome your inquiry.
