Oil press

Abstract

The invention relates to an oil press, which comprises a machine frame, a power device and a temperature control device, wherein the interior of the machine frame of the oil press is provided with a main roll and a plurality of auxiliary rolls, the auxiliary rolls are matched with the main roll, and are sequentially and tightly attached to the periphery of the main roll, a certain distance is formed between the first auxiliary roll and the peripheral surface of the main roll to facilitate the feeding of oil, the gaps between the auxiliary rolls and the peripheral surface of the main roll are gradually reduced until the auxiliary rolls are tightly attached to the peripheral surface of the main roll, the main roll and the auxiliary rolls form a pressing space, the temperature control device is used for adjusting the temperature of the oil in the pressing space, the power device is used for driving the main roll and / or the auxiliary rolls, the oil firstly enters the first auxiliary roll, then is pressed in the pressing space, and is finally treated by the final auxiliary roll, the slag is discharged out, and the pressed oil liquid leaks out via the gaps between the auxiliary rolls. The oil press has the advantages that the oil is pressed and pressurized by the roll pair type of multiple rolls, and the compression type is direct; compared with the existing spiral oil press, the friction loss of power is greatly reduced, namely that the loss of component parts is reduced, and the consumption of energy sources is reduced.

Description

technical field [0001] The invention relates to oil press technology, in particular to a domestic or commercial double-roll oil press. Background technique [0002] Extracting oil by pressing is an ancient and practical method of oil production. Since the power press was used for oil production in foreign countries in the 19th century, the machinery used for oil extraction by pressing is mainly hydraulic oil press and screw oil press. kind of equipment. At present, the equipment used to squeeze oil at home and abroad is mainly a screw press. Hydraulic oil presses are divided into vertical and horizontal types. In my country, vertical hydraulic oil presses are only used in small quantities in rural areas and remote mountainous areas due to their small output, intermittent production, and high labor intensity. Horizontal hydraulic oil presses are basically not developed in China, and horizontal hydraulic oil presses used for large-scale production of sesame oil are imported ...

AI Technical Summary

Problems solved by technology

One of the main problems in the use of the screw oil press is the high maintenance rate, and another problem is the high energy consumption of the screw oil press

[0004] The screw oil press is still difficult to process, the oil outlet hole of the press chamber is easy to block, and the screw shaft and the screw extrusion inside the press chamber are severely worn, which affects the quality of oil output
