Description

I

The invention relates to the dairy industry, namely to cheese presses.

A cheese press is known, which includes a housing, vertically installed racks, shelves, pressing mechanisms with brushes, and pneumatic or hydraulic cylinders with pistons 1.

In a known press, constant pressure is applied to the cheese pan.

In addition, the magnitude of the working stroke of the rod of the pressing mechanism depends on the height of the pneumatic or hydraulic cylinder; therefore, the longer the required stroke, the longer the pneumatic or hydraulic cylinder must be. On these presses it is not possible to carry out the mode of pressing with a pulsating load.

The goal is to reduce the size and provide a pulsating load.

The goal is achieved by the fact that the proposed press is additionally equipped with couplings, each of which is rigidly fixed on the piston, with each stem of the pressing mechanism made with annular grooves and placed inside the piston, and each coupling is provided with a pair of jaws mounted

with the possibility of swing around their horizontal axis and interaction in the process of working with the annular grooves of the shaft.

FIG. 1 shows the proposed press, a general view; in fig. 2 is a section along A-A in FIG. one.

The press consists of a body 1, vertical posts 2, shelves 3, pressing mechanisms 4, a shaft 5 with annular grooves 6, a pneumatic or hydraulic cylinder 7, a piston 8 rigidly connected to a coupling 9, on which cams 10 are attached, which can swing axles 11.

A dog 13 is attached to the bracket 12, having the ability to pivot on an axis 14, which is associated with the cam 10.

The pressing process is carried out as follows. The cam 10 becomes in the position indicated on the drawing by the main lines. The rod 5 with the pressing mechanism 4 under its own weight is lowered onto the pressed mass (not shown in the drawing). Then the piston 8 under pressure of air (liquid) starts to move down from above, transferring pressure to the cheese mass through the coupling 9 and the cams 10. After the piston goes down, the direction of air flow changes and the piston starts to move up. The lower tooth of the cam 10 slides along the grooves of the rod 5, and the stem, under the action of elastic deformation of the compressible mass, rises up by the amount of the latter, thereby allowing the cheese mass to be relieved of pressure. Then the cycle is repeated.

At the end of the extrusion, the cams 10 are set to the position shown by a dotted line. In this case, the rod 5 with the pressing mechanisms moves upwards, thereby releasing the pressed mass from the load.

The proposed cheese press improves the pressing conditions, reduces the metal content of the structure, intensifies the process of dewatering and compaction of the curd when it is pressed, and gives the folk economy a significant economic effect.
