Full-automatic walnut oil press

Abstract

The invention relates to the technical field of walnut processing equipment, and discloses a full-automatic walnut oil press which comprises a fixing box, supporting columns are fixedly installed at the two ends of the bottom of the fixing box, the tops of the supporting columns are movably sleeved with a sealing box, and an oil inlet is fixedly connected to the top of the sealing box; a piston pressing disc is movably connected to the position, located below the oil inlet, in the sealing box in a sleeved mode, and a pressure valve is fixedly installed at the top of the piston pressing disc. Through the arrangement of the pressing rod, the bottom end of the pressing rod pressurizes a walnut cake, the contact face between the pressing rod and the walnut cake is reduced, stress is increased, the pressing rod is slowly inserted into the walnut cake, transverse extrusion on the walnut cake is completed, the internal space of the walnut cake is further compressed, walnut oil can be removed, and the oil pressing rate is increased; the center of the bottom of the walnut cake is pressurized outwards, so that walnut oil can be fully discharged outwards from the middle, the situation that the walnut oil is accumulated in the center of the walnut cake and cannot be discharged is avoided, and the oil pressing rate is further increased.

Description

technical field [0001] The invention relates to the technical field of walnut processing equipment, in particular to a fully automatic walnut oil press. Background technique [0002] The oil content of walnut is as high as 65%-70%, ranking first among all woody oils, so the oil press is used to extract its essence. The walnut oil press currently used is mainly divided into two types: hydraulic walnut oil press and single Spiral walnut oil press, among them, the principle of the hydraulic walnut oil press is: pour the walnut kernel or walnut shell and kernel mixture into the container, and then drive the inner wall of the container to descend and squeeze the walnut through hydraulic pressure, so that the walnut oil is extracted from the walnut Separated to realize oil extraction, but there are some deficiencies in the currently used walnut oil press, as follows: [0003] In the process of squeezing walnuts, the walnuts are gradually compressed into a cake shape under pressur...

Problems solved by technology

[0003] In the process of squeezing walnuts, the walnuts are gradually compressed into a cake shape under pressure, but after compression to a certain extent, the walnut cake cannot be further compressed due to the large contact surface between the pressed inner wall and the cake-shaped walnut. As a result, the walnut oil cannot be discharged, especially when walnut shells and walnut kernels are squeezed together. When some walnut shells are squeezed together, a certain part of the cake is thicker, making the inner wall of the press unable to continue to press down, resulting in other The walnut oil in the place cannot be squeezed out, resulting in a decrease in the discharge of walnut oil and an increase in losses
