Embodiment 1

[0019] 1. Low-temperature drying: Dry the raw material of ginseng seeds through the drying equipment. During the drying process, the temperature of the raw material is controlled below 60°C, the drying time is 58 hours, and the moisture is reduced to 4%. Air cool to room temperature.

[0020] 2. Cleaning and shelling: Take 50Kg of ginseng seeds, clean and remove impurities, and use an impact shelling machine to shell. The complete rate of seed kernels is above 50%, and the shelling rate is above 90%. When the shells and kernels are separated, the shells are left in the kernels. 15%.

[0021] 3. Preparation: The shelled material is prepared in a layered preparation pot so that the material contains 6% moisture and the temperature is 35°C.

[0022] 4. Pressing: Use a twin-screw press for low-temperature pressing, so that the first pressing cake has 25% residual oil and the cake temperature does not exceed 40°C, and the second pressing cake has 15% residual oil and the cake temp...

Abstract

The invention provides a method for preparing ginseng seed oil through cold pressing. The method comprises a complete set of related technologies of the pretreatment of raw materials, temperature control, crude oil refinement and the like. The adopted technical scheme comprises the following steps of: drying at low temperature, namely controlling the temperature of the raw materials to be less than 60 DEG C, and reducing the water content to be less than 5 percent; hulling by a huller and an impact method, wherein the hulling rate is over 90 percent; adjusting, namely adjusting a pressing material to ensure that the water content is 5 to 10 percent and the temperature is 30 to 45 DEG C; pressing, namely performing secondary pressing by a twin-screw press, wherein the content of residual oil of a cake obtained after first pressing is 23 to 30 percent and the temperature of the cake is not more than 45 DEG C, and the content of residual oil of a cake obtained after second pressing is 10 to 15 percent and the temperature of the cake is not more than 70 DEG C; and refining crude oil, namely filtering the crude oil by a plate and frame filter for multiple times, wherein auxiliary filtering layers such as cotton cloth, rice paper and the like are added on filter cloth during the filtration. The ginseng seed oil prepared by the method does not contain any chemical substances, and can be used in health-care food and cosmetics.

Description

technical field [0001] The invention belongs to the technical field of oil processing, and in particular relates to a method for preparing cosmetic-grade and medicinal-grade ginseng seed oil by adopting a low-temperature cold pressing process. Background technique [0002] The whole body of ginseng is a treasure and has extremely high medicinal value. It is a traditional Chinese medicine in my country. Ginseng seeds are rich in oil and have a very high content of unsaturated fatty acids. They have super moisturizing ability and health care function. Due to limited production, there are relatively few studies on the utilization of ginseng seeds, and there are few ginseng seed products sold in the market. Cold pressing oil extraction is an advanced technology for obtaining high-quality oil products developed on the basis of oil extraction technology by pressing in recent years. It is characterized by strong adaptability to oil species, flexible production, and effective main...
