A preparation and processing technology of health-care walnut vegetable oil

Abstract

The invention belongs to the technical field of walnut oil processing, and particularly relates to a health-care walnut vegetable oil preparation and processing technology, which comprises the following steps: 1, walnut shell removal: removing hard shells on the outer layers of the walnuts, and collecting walnut kernels; 2, walnut kernel peeling: soaking walnut kernels in water, heating the water,taking out the walnut kernels, and peeling the walnut kernels; 3, walnut kernel drying: drying the peeled walnut kernels to remove moisture on the surfaces of the walnut kernels; step 4, walnut kernel oil extraction: squeezing the dried walnut kernels to extract oil, and collecting the residues, wherein the process of squeezing out oil in the step 4 is completed by adopting a walnut oil preparation and processing device in a matching manner. The walnut oil is prepared by adopting the preparation and processing technology of the health-care walnut vegetable oil provided by the invention, walnut kernels can be fully crushed and ground, the oil yield of the walnut kernels is improved, and the waste of raw materials is reduced; the surface of the compression roller can be in direct contact with walnut kernels, and the compression roller is prevented from being stuck.

Description

technical field [0001] The invention belongs to the technical field of walnut oil processing, and in particular relates to a preparation and processing technology of health-care walnut vegetable oil. Background technique [0002] Walnut oil is a natural vegetable oil made from walnuts and oil-making process. At present, the commonly used walnut oil oil production process is to send walnut kernels into the pressing rollers that cooperate with each other, so as to squeeze out the oil in the walnut kernels. In actual production, this method has the following problems: (1) It is difficult to fully crush and grind walnut kernels only by the extrusion force of the pressing roller, resulting in a low oil yield of walnut kernels and serious waste of raw materials ; (2) The crushed walnut kernels adhered to the surface of the roller after being crushed by the roller, so that the roller cannot be in direct contact with the walnut kernel during subsequent processing, which reduces the...

Problems solved by technology

[0004] The invention provides a preparation and processing technology of health-care walnut vegetable oil, aiming to solve the following problems existing in the current walnut oil oil production process: (1) It is difficult to fully crush and grind walnut kernels only by the extrusion force of the pressing roller Grinding, resulting in low oil yield of walnut kernels and serious waste of raw materials; (2) The crushed walnut kernels after being rolled by the rollers adhere to the surface of the rollers, which prevents the rollers from directly contacting the walnut kernels during subsequent processing , which reduces the extrusion effect of the pressure roller on the walnut kernel, and seriously reduces the oil yield; the walnut kernel accumulated on the surface of the pressure roller will be stuck between the two pressure rollers after being compacted by the pressure roller, causing the pressure roller to be stuck
