Abstract

The invention relates to a method for extracting part of crude oil from high-oil-content nut jam mud. The method comprises the following steps: performing air separation and dust removal on nuts; removing nut kernel coatings; performing air drying and baking, and grinding in a mincing machine; furthering grinding in a five-roll grinding machine, then heating to 70-95 DEG C, and keeping the temperature for 8-20 minutes; centrifuging in a settling centrifugal machine; sucking out nut crude oil; and further centrifuging by virtue of a tube centrifuge to remove residues so as to obtain clarified crude oil and simultaneously obtain low-oil-content nut jam mud which can be used for production. The method and the system are particularly suitable for efficient utilization of high-oil-content jam mud of pine-nut kernels, walnut kernels and the like, and extraction of crude oil of pine-nut oil, walnut oil and the like. The method for extracting the nut oil, provided by the invention, is implemented by virtue of physical centrifugal action, any organic solvent is not used, or other raw materials for assisting oil expression are not added, so that the obtained nut oil is high in safety; and any high-pressure or vacuum equipment is not used in the extracting process, so that the process equipment system is easy to implement and high in safety.

Description

technical field [0001] The invention belongs to the technical field of food processing, and relates to an extraction process for obtaining high-quality vegetable oil from high-oil nuts (such as pine nuts and walnuts) and a low-oil nut paste that can be used for reprocessing and its supporting system, especially a kind of A method and system for extracting part of crude oil from high-oil nut paste. Background technique [0002] Pine nuts are also known as Luo pine nuts, sea pine nuts, Xinluo pine nuts, red pine nuts, pine nuts, and pine yuan. It has high nutritional value and has certain health care effects. Li Shizhen once gave a high evaluation of the medicinal value of pine nuts. He wrote in "Compendium of Materia Medica": "Sea pine nuts, released as Xinluo pine nuts, have a sweet and non-toxic smell; they are mainly used for joint wind, dizziness, and detoxification. Dead muscles, whitening, dispersing moisture, moistening the five internal organs, chasing wind and numb...
