Abstract

Usage: separation of serum from curd in the production of cottage cheese. SUMMARY OF THE INVENTION: A plant for separating whey from a curd bunch comprises a rectangular body 1 with a perforated cover 4 and a working chamber. The working chamber is made in the form of a mesh frame 7 for fastening the filter material. The framework consists of a series of sections 8 for the product, having a trapezoid shape in cross section with a large base directed toward the perforated cover. Each section for the product is separated from the adjacent section by an air channel. The housing with the working chamber is mounted for rotation around a horizontal axis. 3 or

WITH

The invention relates to equipment for the dairy industry and can be used to separate the whey from the curd in the production of curd.

The famous BC-2.5 bath for separating the whey from the curd bunch, containing a tank mounted on the trolley, on the side walls of which there is a grid. The tank is lined with filter material and loaded with curd. The separation of the serum is carried out by self-pressing the clot.

A disadvantage of the known bath is the low productivity due to the low intensity of the serum separation process.

The closest to the technical essence and the achieved result to the proposed is a device for removal of serum, containing a rectangular vessel, mounted in a frame that can be rotated around a horizontal axis. The product vessel has a lid, the walls, the bottom and the lid of the vessel being perforated to drain the whey. A disadvantage of the known device is also low productivity due to the low intensity of the serum separation process.

The purpose of the invention is to increase productivity by intensifying the process of separation of serum.

This goal is achieved by the fact that in an installation for separating whey from a curd cluster, it contains a rectangular case with a perforated lid and a working chamber with a filtering surface 2

Rotary mounted around the horizontal axis, according to the invention, the working chamber is made in the form of a mesh frame for attaching a filtering material consisting of a series of sections for the product, separated by air channels, each section in cross section having the shape of a trapezium with a large base directed towards the perforated cover,

Figure 1 shows the installation, front view; figure 2 is the same, top view; FIG. 3 shows a section of the working chamber.

The installation for separating the serum from the curd clot contains a rectangular body 1 of welded structure mounted on axes x 2 in bearings 3. The body is equipped with a perforated cover 4, fixed by means of stoppers 5, a mesh frame 7 for fastening a fixing material consisting of a series of sections 8 for a product. As the filtering material, a stainless steel mesh with cells of size (0.25-0.5) mm or a mylar cloth is used. Each section 8 in cross section has a trapezoid shape with a large base directed toward the perforated cover 4. Section 8 is separated by air channels 9, providing cooling of the curd bunch and draining serum over the entire height of the section. The housing 1 of the installation is rotatably mounted about a horizontal axis by means of an actuator mounted on the base 10 and containing an electric motor 11, a gearbox 12 and a V-belt transmission 13. Underneath the housing 1 is a pallet 14 for collecting serum,

The installation works as follows.

Sections 8 of the portable working chamber b installed on the pallet are filled with a curd prepared for dehydration. If lavsan cloth is used as the filtering material of the working chamber, then after filling sections 8 with a clot, wadding is carried out with the left edges of the cloth, fixed with tie-ins and covered with a perforated lid 4 After filling the sections 8 of the working chamber with a curd clot, they are covered with a perforated lid 4. The working chamber filled with the curd clot is transferred and installed by means of an electric hoist

The rectangular casing 1, where chamber b, and lid 4 are fixed by stoppers 5. Then, the working chamber 6, sections 8 of which are filled with curd, is left at rest for 15 min to release the serum, after which the body 1 is rotated camera at 90 ° and leave them alone for 15 minutes. Thus, one rotation of body 1 in 60-70 minutes is carried out, and after each rotation of body 1 by 90 °, the periodic lag is 15 minutes. In this case, when the working chamber 6 rotates around the horizontal axis of the installation, the cottage cheese clot is pressed in due to the trapezoidal section of the sections 8 due to the uneven distribution of its mass over the height of the sections, which ensures an intense separation of the serum. the working chamber 6, enters the air channels 9 and flows into the pallet 14. The air channels 9, which divide the sections 8 of the working chamber among themselves, contribute in advance in cooling curd clot. At the end of the dewatering process, the working chamber 6 is removed from the installation body 1 by means of an electric hoist and transferred to the refrigerating chamber for the final cooling of the curd bunch by forced air flow. Then, the sections 8 of the working chamber 6 are freed from the cooled cottage cheese bunch, the chamber is subjected to washing, drying and sent to fill a new batch of cottage cheese bunch requiring dehydration.

The use of the proposed plant will improve productivity by intensifying the process of separation of serum.
