The technical result is achieved due to the fact that the device for filtering food liquids, mainly milk, containing a vertical cylindrical body having an inlet pipe in the lateral cylindrical surface with a vertical plate at the entrance to the cavity of the vertical cylindrical body, the lower end of which is made in the form of a disk with a central hole, under which the outlet pipe is located, and the upper end of the housing, equipped with an external screw thread, is closed by a lid having an internal screw thread, food rubber adhesive and external processes for unscrewing, an internal filter element mounted with an annular gap relative to the housing, a fixing adapter with holes on the walls, mounted on the said disk above its hole with the possibility of landing fastening on it one end of the filter element made in the form of a tubular cartridge made of food-grade polymer material, removing the adapter with holes on the walls, mounted in the center of the inner surface of the lid with the possibility of landing fastening on the second end of the filter element, characterized in that the device for filtering food liquids, mainly milk, is additionally equipped with a stainless steel mesh with cells of 0.05-5.00 mm in size, said mesh being installed between the housing wall and the filter element with a clearance of 0, 00-10.00 mm.

Improving the quality of milk filtration and increasing the service life of the filter element is achieved due to the fact that the inventive device is equipped with a stainless steel mesh with mesh size of 0.05-5.00 mm mm, and the gap between the wall and the filter element is 0.00-10, 00 mm.

In analogues, when filtering milk, large particles of dirt falling into the radial diffuser channels of filtration block them immediately at the beginning of each channel. The channels are clogged with contaminants, as a result of which the throughput is reduced, the service life of the filter element is reduced.

In the inventive device, a stainless steel mesh with cells measuring 0.05-5.00 mm, a gap between the wall and the filter element of 0.00-10.00 mm provide rough cleaning of milk from large particles of dirt. The mesh cell sizes are determined experimentally, depending on the contamination of the liquid. The gap between the wall of the housing and the filter element is regulated depending on the pressure at which milk enters the filter housing and is adjustable in the range of 0.00-10.00 mm. As a result, the quality of milk filtration is increased and the service life of the filter element is increased.

In the inventive device for filtering food liquids, mainly milk, the listed disadvantages of the known designs are eliminated.

The claimed technical solution meets the requirement of industrial applicability, since it is manufactured and actively implemented at dairy farms in Voronezh, Novosibirsk and other regions, as well as in the Altai Territory, Ukraine and Belarus.

The utility model is illustrated by the drawing, which shows a device for filtering food liquids, mainly milk.

A device for filtering food liquids, mainly milk, contains a vertical cylindrical body 1 having an inlet pipe 2 in the lateral cylindrical surface, the end of which is made in the form of a disk 3 with a central hole 4, under which the outlet pipe 5. is placed, the inlet pipe 2 in the lateral cylindrical surface on the entrance to the cavity of the vertical cylindrical body 1 has a vertical plate 13. The upper end of the cylindrical body 1 is closed by a cover 6. Inside the body 1, the inner th filter element 7, mounted with an annular gap 8 relative to the housing 1. This food fluid filtering device is equipped with a fixing adapter 9 for fastening the filter element 7 in the housing 1 and a removal adapter 10 for changing the filter element 7. The fixing adapter 9 is mounted on the disk 3 above it hole 4 with the possibility of landing fastening on it one end of the filter element 7. The removing adapter 10 is fixed in the center of the inner surface of the cover 6 with the possibility of landing fastening on it of the second end filter element 7. The wall of the filter adapter 9 and the wall of the removal adapter 10 are provided with holes 14. The upper end of the housing 1 is provided with an external screw thread 11 for connection with a cover 6 having an internal screw thread (not shown in the drawing), a gasket made of food rubber (in the drawing not indicated) and external processes 12 for unscrewing. The filter element 7 is made in the form of a tubular cartridge made of food-grade polymer material (polymer plastic), for example food-grade polypropylene. The inner cavity 15 of the tubular cartridge of the filter element 7 is used to collect purified liquid and is connected through an opening 4 of the disk 3 with the outlet pipe 5. Between the wall of the cylindrical housing 1 and the filter element 7 a stainless steel mesh 16 with cells of 0.05-5.00 is installed mm, while the gap between the wall of the housing and the filter element is 0.00-10.00 mm The quality of milk filtration depends on the size of the contaminants, on the level of milk contamination. Cell sizes of 0.05-5.00 mm were determined experimentally. All polluting particles with sizes greater than 5.00 mm do not pass through the mesh and do not clog the pores of the filter element 7.

All polluting particles with sizes less than 0.05 mm pass through the grid and enter the conductive radial confuser channels of the filter element, where they are subsequently detained.

The clearance between the housing wall and the filter element of 0.00-10.00 mm are selected experimentally. When the gap value is less than 0.00 mm, the mesh 16 will be pressed against the filter element 7 and block up to 30% filtering conductive radial confuser channels of the filter element 7, which in turn will reduce the throughput and the filtering area of the filter element 7.

When the gap value is more than 10.00 mm, the mesh 16 will be pressed against the hole of the inlet pipe 2 of the housing and will reduce the throughput and filtering area of the mesh 16.

The inventive device operates as follows.

A device for filtering food liquids, in particular milk, is connected to a milk purification system and a pump is turned on to start the filtration process. In this case, the milk contaminated with solid particles under pressure enters the housing 1 radially through the inlet pipe 2, under the additional pressure created by the vertical plate 13, into the filter cavity of the cylindrical housing 1 through a stainless steel mesh 16 with cells of 0.05-5 , 00 mm, and, having distributed along the annular gap 8 along the perimeter of the housing, is guided along the filter element 7 into the inner cavity 15 of the filter element 7, milk without resistance quickly passes through the holes 14 in the walls of the fil truyuschego adapter 9 and removes the adapter 10 and further through the drive opening 4 to the outlet conduit 5, from which comes the milk purified, e.g., into a jar for milk or milk tanker tank. Large dirt particles do not penetrate the filter element 7 and do not block the entrance to the conductive radial confuser channels (not shown in the drawing).

Technical and economic effect.

The inventive device since 2006 is being introduced at dairy farms in Voronezh, Novosibirsk and other regions, as well as in the Altai Territory, Ukraine and Belarus. Using a device for filtering food liquids, mainly milk, allowed to improve the quality of milk filtration, to increase the life of the filter element.
