Description

The invention relates to the oil industry, in particular the production of edible vegetable oil.

The closest in technical essence and the achieved result is an oil squeezer containing a housing, a grain cylinder with holes for oil exit, a screw with a tapered end and an end sleeve with grooves on the tapered recess and with a central hole for the exit of the cake, the inner surface of the grain cylinder is made with longitudinal protrusions located on the side of the end sleeve, and the screw in this place has a corresponding underestimation of the outer diameter and grooves on the conical surface of the end, while the holes for the exit of oil, the grain cylinder is made in the form of slots located perpendicular to the axis of the screw [RF Patent No. 204192, Bull. No. 23, publ. 08.20.95, C 11 V 1/06].

The known design of the press has the following disadvantages:

- does not allow to obtain high quality oil from seeds of low oil crops due to insufficient time spent in the zone of intensive exposure;

- does not allow you to adjust the outlet in the chamber for oil exit, which can lead to excessive ingress of pulp into the finished product;

- low yield of oil from seeds of low oil crops.

An object of the invention is to increase the yield of high-quality oil from seeds of low-oil crops, the ability to control the outlet openings and increase the residence time of the product in the zone of intense compression.

The technical problem is achieved in that in a press for producing edible vegetable oil, comprising a housing with a loading hopper and an auger, a chamber with openings for oil outlet and a central outlet for the outlet of a cake, a new feature is that an additional chamber with a screw discharge element is installed in the housing and openings for the exit of oil, the end part of which is concave in the form of a sphere with curved grooves and an opening for the transition of the product from one chamber to another, and the inner part of the groove chamber does not contain ie, the end portion of the screw is convex in the form of spheres, and the output of the additional chamber openings and a central opening for exit cake provided with regulating devices in the form of movable cone

The technical result consists in increasing the yield of oil from low-oil crops, in the possibility of regulating the flow area of the holes of the chamber for oil exit and increasing the residence time in the zone of intense compression.

Figure 1 shows a General view of the press; figure 2 is a section aa; figure 3 is a section bB; figure 4 - General view of the regulatory device

A press for producing edible vegetable oil comprises a housing 1 with a loading hopper 2, a chamber 3 with openings for the exit of oil 4, a screw 5, the end part of which is convex in the form of a sphere, and an additional chamber 6 with openings for the exit of oil 7, the end part of which is made concave in the form of a sphere with curved grooves 8, a central hole 9 for transferring the product from one zone to another, a screw discharge element 10, a tightening nut 11 and a sleeve 12 with a central hole 13 for the exit of the cake, adjusting devices 14 for adjusting the bore of the central hole and the oil outlet.

Press works as follows.

In the loading hopper 2 of the housing 1, a low-oil feed is loaded, which enters the screw 5. Next, the raw material moves with the screw through the chamber 3, the oil outlet 4. When the zone of intense compression is reached, the raw material enters the end part of the additional chamber 6, made in the form of a concave sphere with curved grooves, which allows you to increase the residence time in the zone of intense compression due to the fact that the grooves are made along a curved path. Then the partially pressed raw material through the central hole 9 enters an additional chamber, where the final extraction of the oil-containing raw material and a more intensive release of oil takes place. The cake is discharged through the opening 13 of the sleeve 12, and the oil exits through the openings 7 of the additional chamber to the receiving tank [not shown in FIG. 1].

This press can operate in the oil extraction mode of high-oil crops as well, which is provided by opening and adjusting the bore of the openings 4 of the chamber 3, and the openings 7 of the additional chamber are closed.

To adjust the bore of the oil outlet openings 4 and 7, as well as the outlet for the oil cake 13, the press is equipped with a regulating device in the form of a movable cone, shown in Fig. 4, which consists of a fitting 15, a connecting sleeve 16, an adjusting screw 17. During of the operation of the press, the product moves along the central channel of the fitting 15, which decreases in volume, and both oil and cake can exit at the outlet, depending on what function the regulating device performs (i.e. where the device is installed), and adjustment Khodnev section exiting from the press cake, and oil is carried out by rotating the adjusting screw 17, there is a change in the gap (s). Depending on the type of oil-containing culture, the size of the gap can vary from 0.10 ... 3 mm.

This press has the following advantages:

- universality, as it can receive oil from crops that are different in oil content;

- allows you to increase the yield of oil from the seeds of low oil raw materials due to double compression;

- allows you to adjust the orifice of the hole: both for the exit of oil, and for the exit of oilcake, which allows you to get oil from crops with different contents;

- allows you to increase the time spent in the zone of intense compression due to the curved grooves on the spherical recess.
