Embodiment 1

[0021] Embodiment 1: a kind of method extracting sorbifolia oil from sorbifolia seed, its main feature is to comprise the steps:

[0022] (1) Screening, cleaning, and drying the raw materials of sorbifolia seeds until the water content is ≤13%, the drying temperature is 60° C., and the drying time is 60 minutes; then, it is crushed to 40 mesh by a pulverizer;

[0023] (2) Put the dried and pulverized Xantho sorbifolium seeds into the extraction kettle, and vacuum down to 1×10 4 Below Pa, discharge the air in the extraction kettle; then use a plunger pump to introduce tetrafluoroethane solution into the extraction kettle, control the extraction temperature to 30°C, the extraction pressure to 1.0Mpa, each extraction time is 40min, and repeat the extraction 3 times; Then separate, the separation temperature is 45 °C, and the negative pressure is gradually reduced to 5×10 with a diaphragm compressor. -2 Pa, each separation time is 30min, and the separation is repeated 3 times to ...

Abstract

The invention belongs to the field of plant grease extraction and particularly relates to a method for extracting shiny-leaf yellowhorn oil from shiny-leaved yellowhorn seeds by adopting a supercritical tetrafluoroethane fluid. The method for extracting shiny-leaf yellowhorn oil from shiny-leaved yellowhorn seeds comprises the following steps: crushing the shiny-leaf yellowhorn seed raw material to 40-60 meshes, and repeatedly extracting three times at 30-40 DEG C and 1.0-1.2MPa, wherein the extraction time every time is 30-40 minutes; pumping negative pressure by using a diagram compressor at the separating temperature of 45-55 DEG C and gradually reducing the pressure to 5*10<-2>Pa, and repeatedly separating three times, 20-30 minutes per time; and finally, carrying out centrifugal separation and filtration on the crude shiny-leaf yellowhorn oil by a high speed refrigerated centrifuge to obtain a shiny-leaf yellowhorn oil product. Experiments verify that the yield of the shiny-leaf yellowhorn oil under the above process conditions is 31.8%, and the product quality is good.

Description

technical field [0001] The invention belongs to the field of vegetable oil extraction, and in particular relates to a method for extracting radix sorbifolia oil from radix sorbifolium seeds by using a subcritical tetrafluoroethane fluid. Background technique [0002] Xanthoceras Sorbifolia (Xanthoceras Sorbifolia), also known as Xanthoceras Sorbifolia, belongs to the Sapindaceae Xanthoceras genus, deciduous trees or shrubs, and is an excellent ecological economy unique to my country that is suitable for growing in the north of the Yangtze River. species. The oil content of its seeds is 30% to 36%, and the oil content of its kernels is 50% to 60%. It is known as "Northern Camellia oleifera" and is a promising woody oil plant in northern my country. [0003] At present, the methods of extracting Xanthania sorbifolium oil generally include pressing method, organic solvent extraction method and supercritical CO2 extraction method. 2 fluid extraction. Although the pressing meth...
