Walnut cold-pressing expeller

Abstract

The invention relates to a walnut cold-pressing expeller. The walnut cold-pressing expeller comprises a pressed cage, a feeding passage, a material pushing and cold pressing mechanism, and a cake checking head, wherein the pressed cage is horizontally arranged on a rack; a plurality of cage bars respectively extending to openings of the two ends of the pressed cage are arranged on the inner wall of the pressed cage in the circumferential direction of the pressed cage and are uniformly distributed at intervals in the circumferential direction of the pressed cage; one ends of the plurality of cage bars jointly form a feeding hole; slag discharging holes are formed in the other ends of the plurality of cage bars in a connecting and communicating manner; the feeding passage is arranged on therack in the axial direction of the pressed cage; one end of the feeding passage is connected to and communicates with the feeding hole; a charging hole is formed in the upper end of the feeding passage; the material pushing and cold pressing mechanism is arranged at the other end of the feeding passage and is used for pushing materials added at the charging hole into space among the plurality of cage bars and extruding the materials; the cake checking head is in transmission connection with a driving mechanism; and the driving mechanism is used for driving the cake checking head to horizontally move in the axial directional of the pressed cage till the cake checking head is leaned against or separated from slag discharging hole. The walnut cold-pressing expeller has the advantages that thecontinuous pressing can be realized, by-products can be recycled and deeply processed, the operation labor intensity of equipment is small, the environmental pollution is avoided, and the walnut cold-pressing expeller is simple to use, convenient to maintain and has high production efficiency.

Description

technical field [0001] The invention relates to oil pressing equipment, in particular to a walnut cold pressing machine. Background technique [0002] my country's walnut planting and walnut production rank first in the world. Walnut oil is rich in nutrients and is beneficial to human health. In the international market, walnut oil is known as "Oriental olive oil" and is favored by consumers. [0003] At present, walnut oil extraction is a difficult problem, because walnut oil content is as high as %-%, when hot pressing is used, some walnut shells and other additives must be added to the walnut kernel, and the nutrients of walnut oil after hot pressing are destroyed, so it cannot be used as high-grade edible oil , The cake is basically used as feed, and the by-products cannot be further processed, resulting in a serious waste of walnut protein resources. At present, the walnut oil extraction process is small-scale hot pressing, which cannot be mass-produced. Contents of t...
