A processing device for cold-pressed walnut oil

Abstract

A processing device for cold-pressed walnut oil is disclosed. The device includes a device main body, and includes a control assembly, a high-pressure cold pressing device, a spiral cold pressing device, a squeezing cold pressing device, a coarse filter, and a fine filter which are accommodated in the device main body. The high-pressure cold pressing device, the spiral cold pressing device and thesqueezing cold pressing device are connected through a material passage. The device main body is provided with a material inlet and a material outlet. The material passage is connected to the material inlet and the material outlet. The control assembly includes a PLC controller, a pressure control module connected to the PLC controller, and a plurality of pressure sensors connected to the pressure control module. A manner of a plurality of times of pressure increasing and pressing is adopted by the high-pressure cold pressing device. The pressure sensors are evenly disposed around a pressingchamber of the high-pressure cold pressing device in a flushed manner. The processing device can effectively ensure quality of the walnut oil, can effectively preserve nutrients in walnut kernels, canallow the walnut oil to be rich in trace elements, and can increase the yield of the walnut oil.

Description

technical field [0001] The invention relates to the technical field of edible oil production, in particular to a cold-pressed walnut oil processing equipment. Background technique [0002] Walnuts, belonging to the dried fruit of Juglandaceae deciduous trees, are listed as one of the four major nuts in the world, mainly distributed in America, Europe and Asia. In our country, it is also widely planted and applied. Because of its rich nutritional value, it has been respected by more and more people. [0003] Walnut kernels are rich in walnut oil, which is rich in unsaturated fatty acids, multivitamins, calcium, iron, magnesium and other trace elements, which can be used for health care. It is a kind of high-nutrition woody vegetable oil. The majority of consumers love. [0004] The existing processing equipment for producing walnut oil basically adopts the traditional high-temperature pressing mode or single cold pressing. Due to the high content of unsaturated fatty acids ...

AI Technical Summary

Problems solved by technology

[0004] The existing processing equipment for producing walnut oil basically adopts the traditional high-temperature pressing mode or single cold pressing. Due to the high content of unsaturated fatty acids in walnut oil, high temperature will accelerate oxidation and rancidity, resulting in unqualified oil products. Single cold pressing will lead to walnut The oil extracted from kernels is not thorough, and the nutrients cannot be fully developed

The traditional processing and refining method of walnut oil lacks thorough spiral and extrusion cold pressing of walnut kernels, and cannot fully utilize walnuts. In addition, the walnut oil obtained through traditional processing has a bitter taste, and various additives need to be added to remove the bad taste. Here At the same time, the nutrients in the walnut oil will also be removed, resulting in a serious loss of nutrients and a reduction in the yield of walnut oil.
