Description

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

A known oil squeeze press comprising 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 face, while the holes for oil outlet of the grain cylinder are made in the form of slots, located perpendicular to the axis of the screw [RF Patent No. 2296153, bull. No. 9, publ. March 27, 2007, C11B 1/06].

The known design of the press has the following disadvantages:

- does not allow to obtain high quality oil from oilseeds 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 oilseeds.

The closest in technical essence and the achieved effect is a press for obtaining edible vegetable oil [RF Patent No. 2296153, Bull. No. 9, publ. 03/27/2007, СВВ 1/06], comprising a housing with a loading hopper and an auger, a chamber with holes for oil exit and a central hole for the exit of the cake, while an additional chamber with a screw discharge element and holes for oil exit is installed in the housing, the end part which is made concave in the form of a sphere with curved grooves and an opening for transferring the product from one chamber to another, and the inside of the chamber does not contain grooves, the end part of the screw is convex in the form of a sphere, while the outlet openings are additional The chamber and the central hole for the exit of the cake are equipped with control devices in the form of a movable cone.

The disadvantage is the low yield of oil from oilseeds due to the fact that in the zone of intense compression between the product and in its pores, part of the oil is blocked and its outflow to the outlet openings is impeded.

An object of the invention is to increase the yield of oil from oilseeds, due to alternating effects on the product in the zone of intense compression.

The technical task of the invention is achieved by the fact that in the press to obtain edible vegetable oil, comprising a housing with a loading hopper and a screw, the end part of which is convex in the form of a sphere, while the housing has an additional chamber with holes for oil exit and a central hole for the exit of the cake , the end part of which is made concave in the form of a sphere, it is new that a piezo is installed behind the end part of the additional chamber, placed with the possibility of reciprocating motion eramichesky radiator in the form of a flat washer which is connected via a power amplifier with a master oscillator.

The technical result consists in increasing the yield of oil from oilseeds, due to the alternating effect on the product in the zone of intense compression.

Figure 1 shows a General view of the press; figure 2 is a section aa in figure 1; figure 3 is a section bB in figure 1; figure 4 is a 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. Behind the end part of the additional chamber 6, which is arranged with the possibility of reciprocating motion, a piezoceramic emitter 15 is installed in the form of a flat washer connected through a power amplifier 16 to a master oscillator 17.

Press works as follows. An oil product is loaded into the loading hopper 2 of the housing 1, which enters the screw 5. Then the product moves with the screw through the chamber 3 with openings for oil exit 4. When the zone of intense compression of the oil product reaches 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.

When the oil product is intensively compressed and squeezed between its particles and in its pores, a part of the oil is blocked, therefore, for its outflow to the outlet openings, an alternating effect is exerted on the product by generating oscillations in the piezoceramic emitter 15, which are transmitted to the additional chamber 6, causing it to reciprocate, as a result of which its end part interacts with the product.

Then the partially squeezed product through the central hole 9 enters an additional chamber, where the final extraction of the oil-containing product 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 holes 4 of the chamber 3, and the holes 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 exit 13, the press is equipped with a control device in the form of a movable cone, which consists of a fitting 18, a connecting sleeve 19, an adjusting screw 20. During operation of the press, the product moves along the central the channel of the fitting 15, which decreases in volume, and at the outlet, 10 can be either oil or oil cake, depending on what function the regulating device performs (i.e. where the device is installed), moreover, The cake coming out of the press, as well as the oil, is carried out by rotating the adjusting screw 20, the gap (s) changes. Depending on the type of oil-containing culture, the gap can vary from 0.10 ... 3 mm.

The advantage of this press is that the installation behind the end part of the additional chamber, placed with the possibility of reciprocating motion, of a piezoceramic emitter in the form of a flat washer connected through a power amplifier to a master oscillator, allows to increase the oil output from oilseeds due to alternating action on the product in the zone of intense compression and release of the part of the oil blocked between the product and in its pores and ensuring its unhindered flow ka to the outlet.
