Description

 The invention relates to devices for the manufacture of cheese, in particular to devices for processing cheese curd and grain.

 Known cheese producer containing a double cylindrical tank, a twin mixer with two blades for cutting and mixing, mounted for rotation inside the tank (see USSR patent N 1503676).

 The disadvantage of the known device can be considered the complexity of its manufacture and the fact that with such an installation of a cutting-kneading tool, not the entire volume of the tank is to be processed, in addition, when cutting a cheese clot, segments similar in shape to balls are obtained, which makes it difficult to exit moisture during further drying of cheese .

 Closest to the proposed is a bath for the production of cheese grain by A. with. USSR N 497005, containing a double-walled container with forming brackets in the inter-wall space, a multi-speed reversible drive, a device for raising and tilting the bath, a universal cutting and kneading tool, and a device for selecting serum.

 The disadvantages of the known device include the incomplete coverage of the volume occupied by the cheese clot of the bath with a cutting-kneading tool, i.e. from the ends of the bath, zones are formed that do not provide a rational form of cheese grain.

 The purpose of the invention is to improve the quality of cheese by creating grain with the necessary surface shape.

 This goal is achieved by the fact that in a cheese-maker, which includes a cylindrical vertical bath with heat-insulated side walls, mounted on supporting posts, a device for selecting serum, a cutting-kneading mechanism placed along the axis of the bathtub with an electric motor drive, gearboxes and technological tools, a planetary gearbox is cutting - the kneading mechanism is made with a stopped central wheel and a rotating housing with two output shafts mounted for rotation in the opposite direction. opolozhnyh directions at unequal distances from the axis of the bath, to which are attached two raznoplechih lever, the free ends of the latter arranged parallel to the vertical axis of symmetry of the two sleeves bath for fastening technology tools for processing the curd and grains, and one of the racks is adjustable in height.

 Technological tools for processing cheese clot and grain can be either interchangeable (knife and string frames, paddle mixers, mounted in pairs on axes on the free ends of different levers), and universal in the form of contours with edges sharpened in one direction, and rows of vertical knives with a section in the form of an elongated trapezoid, conjugated along a small base with a triangle, or in the form of an elongated trapezoid with a rounded small base.

 The adjustable support column includes a hydraulic cylinder with an additional drive.

 In addition, on the side surface of the bath is an additional device for the selection of serum.

 Achieved as a result of using the proposed design, the technical effect is that 96% of the bottom area of the cheese producer’s bath is kneaded and cut with the desired quality.

 Technological tools, the axes of which are fixed in the bushings at the free ends of the levers of different shoulders, rotate towards each other, because the output shafts of the planetary gearbox rotate, and at the same time the output shafts of the planetary gearbox located on its rotating casing move in a circle, ensuring cutting of the cheese clot into segments and subsequently into cheese flakes of a scaly shape with a large outer surface, which ensures a quick exit of moisture from the inner layers cheese grains.

 The implementation of one of the supports of a cylindrical bathtub of a cheese producer adjustable in height allows the body to be tilted for the final discharge of whey and removal of cheese grain.

 The introduction of an additional device for the selection of serum increases the manufacturability of interoperative discharge.

 Reversible multi-speed drive and the ability to use a universal technological tool for processing (cutting, kneading, crushing) cheese grains allows high-quality cutting of the bunch during rotation in one direction and mixing of cheese grain during rotation in the other direction. The universality of the tool is determined by its design in the form of a frame combining a contour with edges sharpened in one direction, with rows of vertical knives of a special profile.

 Improving the quality of the resulting product is also ensured by the possibility of using interchangeable technological tools in pairs installed in the device.

 The invention is illustrated in the drawing, where in FIG. 1 shows a General view of the cheese maker in the context; in FIG. 2 - design of an adjustable support; in FIG. 3 - universal cutting-kneading tool; in FIG. 4 - section AA in FIG. 3; in FIG. 5 is a view B of FIG. 4; in FIG. 6 is a view B (variant) of FIG. 4; in FIG. 7, 8, 9 - the design of the framework of the string and knife, and paddle mixer, respectively; in FIG. 10 - the shape of the cheese segment after cutting.

 The cheese-maker contains a vertical cylindrical bath 1 made of stainless steel with heat-insulated side walls. Bath 1 is equipped with a steam-heated lower heat zone 2, the lower half 3 of the side walls of bath 1 (side thermal zone) is also heated with steam. Steam is supplied separately to the lower 2 and lateral 3 thermal zones.

 The cutting-kneading mechanism 4 is suspended on a tricycle frame 5 mounted on the upper edge of the bath 1.

 The cutting-kneading mechanism 4 for processing cheese curd and cheese grain consists of an electric motor 6, for example, an asynchronous three-phase, reduction gear 7 and distributing planetary gear 8 with two output shafts 9 parallel to the axis of the cylindrical bath 1 and rotating towards each other. The shafts are installed on the same line at an unequal distance from the center (bath axis 1).

 Planetary gearbox 8 is made with a fixed central wheel "a" and a rotating housing "in" the gearbox. The axis of symmetry of the gearboxes 7 and 8 coincide with the vertical axis of symmetry of the bath 1.

 The inclined levers of different levers 10, 11 are mounted on the output shafts 9. At the free ends of the levers in the bushings 12, the necessary technological tool for processing cheese clot and cheese grain is installed. The vertical axis of the bushings 12 are parallel to the vertical axis of symmetry of the bath 1. For each revolution of the housing “in” the planetary gearbox 8, there are six revolutions of the shafts 9, on which the levers 10, 11 with technological tools are mounted.

 On the sleeve 12, you can install a universal technological tool 13 (see Fig. 3, 4, 5, 6), made in the form of a contour 14 with sharpened in one direction edges 15 and rows of vertical knives 16.

 The profile of the knives 16 may be an elongated trapezoid with a rounded small base (see Fig. 5). In cross section (see Fig. 6), the knives 16 can also be an elongated trapezoid, mating along a small base with a triangle.

 As technological tools, either the string frames 17 (see Fig. 7), or the knife frames 18 (see Fig. 8), or paddle mixers 19 (see Fig. 9) can be installed in pairs on the free ends of the levers 10, 11 .

 The vertical axis 20 of the technological tools are parallel to each other and the axis of symmetry of the bath 1.

 Bath 1 rests on racks 21, 22. At the bottom of the bath, a drain valve 24 is located on the neck 23.

The support column 22 (see figure 2) is made adjustable in height, it contains in the middle part a hydraulic cylinder 25, which allows, while working with a manual hydraulic pump 26, to tilt the bath 1 by 5 ^o towards the drain neck 23.

 On the side wall of the bath 1 above the lateral heat zone 3 and above the swing axis of the bath 1 there is an additional device for the selection of serum in the form of a valve 27 with manual control.

 In addition, a current frequency converter 28 is connected to the electric motor 6, which makes it possible to smoothly control the number of revolutions of the electric motor and change the direction of rotation.

 The device operates as follows.

 The production of cheese is carried out at parameters (temperature, time, etc.) specified by the technological process of obtaining a certain type of cheese.

 The bath is filled with milk, all the components necessary for coagulation are added and heated to the coagulation temperature by supplying steam to the lower 2 and side 3 thermal zones.

 The milk is heated with constant stirring, for which they turn on the electric motor 6. Gearboxes 7, 8 are actuated. The levers 10, 11 are fixed on the rotating output shafts 9, and on them are either universal technological tools 13 or paddle mixers 19.

 When the coagulation temperature is reached, the drive is turned off and the mixture is left until a clot forms, maintaining the set temperature in it.

 After the formation of a cheese clot, the coolant (steam) flow to the heat zones 2, 3 is stopped. The levers are either equipped with universal technological tools 13, or string frames 17 or knife frames are installed 18. The drive 6, 7, 8 is turned on again and the cheese clot is cut into segments scaly shape (see Fig. 10).

 After cutting the cheese clot, the drive is stopped, and through the valve 27, a partial selection of serum is performed.

 When using a replaceable technological tool, the string frames 17 or knife frames 18 are replaced by paddle mixers 19. And when using the universal tool 13, the direction of rotation by the current frequency converter 28 is reversed. The drive turns on and the cheese is kneaded (grain setting). At the same time, a second heating of the cheese grain is performed.

When the mixture of cheese grain and whey has a predetermined temperature, the flow of coolant is stopped, the drive is turned off and the final whey is drained together with cheese grain through valve 24, after tilting the bath by 5 ^° using the hydraulic cylinder 25.
