Description

GERMAN

In the production of different types of cheese (round-piped cheese sorts), the cheese mass that is too a cheese curd has been crushed in the cheese vat, usually into a cake of more uniformity Pre-pressed thickness at the bottom of the tub, and then hand-cut the cake into a desired number divided as much as possible equal parts. These pieces or blocks of cheese are hand picked from the bottom of the Lifted out the tub and then placed each block in one of the cheese molds in which the final pressing happens. This division of the pre-pressed cheese mass by hand requires a great deal of time and can not performed with the accuracy required to make the blocks of cheese the same size or at least roughly the same. The blocks of cheese produced in this way therefore give way vary considerably in both size and weight. Highlighting the am Bottom of the tub shaped blocks of cheese is also a very heavy and time consuming job because of the weight the blocks of cheese in a single vat is usually around 500 kg. "- - -

There has already been proposed a device for cutting thick milk that consists of a frame with a number of cutting wires clamped in this. This cutter lies on the floor a container in which the milk clot is to be made, and is provided with a lifting device connected to the top of the container. When the formed clot ruptures, the frame that has the same shape as the cross-section of the container, and the cutting wires through the mass by means of the Lifting device pulled up., With the mass over the entire cross-section of the container in a large Number of small, prismatic parts being cut. Such a cutting has only the task to facilitate the drainage of the whey from the clot during the subsequent straining, that in a special one Sieving device and is carried out in a special operation. Mass broken in this way can then be used to make cheese and is pressed into a cake for this purpose, then by means of another suitable cutting device in for the cheese or press molds appropriate pieces is cut up. This makes the whole process of making cheese very much cumbersome and time consuming.

The object of the invention, which relates to a device for cutting, pressing and simultaneous Raising cheese mass is aimed at making the operations easier and at the same time to avoid the aforementioned disadvantages. The device according to the invention is essentially characterized by a container with a basket or the like.,

which is arranged in this and can be raised and lowered with the help of a lifting device, a preferably perforated pressure plate which is removably arranged above the basket and against which the cheese mass is pre-pressed when lifting the basket, and a knife frame od is arranged above the press plate and against which the cheese mass after removing the press plate by further lifting the basket can be pressed and through which the cheesecake, which has been formed into a number of blocks of cheese by pressing the cheese mass against the press plate is cut, which are preferably of the same size and ready for subsequent pressing in cheese molds suitable.

The invention is described in more detail below in connection with the drawings, namely show Fig. 1 and 2 each a vertical view in section along two mutually perpendicular planes through a device according to the invention. The device shown has a container 1 of rectangular Cross-section provided with an outlet valve 2 at the bottom and an overflow 3 at its upper end through which excess whey can escape. There is a basket with two in the container Side walls 4 and a bottom 5 made of sieve-like plates. The other two sides of the basket are

completely open, and the width of the basket between these sides is in proportion to the width of the container sized so that the side walls of the container delimit the areas enclosed by the basket Form chamber. Between the edges of the basket walls 4 and the bottom 5 and the sides of the walls Container 1 packing cords 6 are arranged. The basket is on its outside with a housing or frame 7 provided from tubes or rods against which the side walls 4 and the bottom. 5 support and by which the basket is suspended from a lifting device which is carried by a pipe or Rod assembly 8, a piston rod 9 and a with this connected piston 11, which is movable in a cylinder 10, is formed. Through compressed air lines 12., 13 and 14 and a control valve 15 can pressurized air into a cylinder 10, which by means of a Rods 16 existing frame is rigidly connected to the container 1, alternately at the bottom and are introduced at the top of the piston 11, whereby the basket in the container 1 is raised or is lowered. Above the basket and on the upper edge of the container 1 is one with openings provided pressure plate 17 releasably attached, which is parallel to the bottom 5 of the basket and also with packing cords 6 is provided and against which the cheese mass is pressed into a cake when the basket is lifted will. Above the press plate 17 there is a knife frame made of longitudinal and transverse knives 18, which supports the press plate during the pressing process and against which the cheese mass after the Press plate 17 has been removed and further lifting the basket to cut the cheesecake can be pressed into blocks of cheese of suitable size. The press plate 17 rests on one in the upper edge of the container arranged fold, which also supports the knife frame 18. Both the press plate 17 and the knife frame 18 can be detached from the container with the aid of screw terminals 19 or the like attached so that they can be easily removed. The basket is with the help of rods 20, which with the frame or housing 7 are connected and provided with slots 21 on the pipe or rod assembly 8 hung so that the basket, after it has been lifted out of the container, can be shifted laterally, whereby the outer surfaces of the basket and the interior of the container 1 easily accessible for cleaning.

When using the device described, the cheese mass obtained in a cheese vat is combined brought into container 1 with the whey. Excess whey can escape through the overflow 3. When the container 1 is filled, the press plate 17 and the knife frame 18 are removed beforehand, and the basket is in its lowered position. The press plate 17 is then in its correct Place in the container together with the knife frame 18 and both are used with the help of Screw terminals 19 attached. The whey level in the container 1 is determined by the position of the overflow 3. The overflow is expediently arranged so that the pressure plate 17 is slightly above the Whey surface is in the container. By supplying compressed air to the chamber below the piston 11 in the cylinder 10 via the lines 12 and 13 and the valve 15, the piston 11 is thus also the Basket in container 1 raised. The cheese mass in this container is simultaneously up against the Press plate 17 pressed and into a cake of uniform thickness and of suitable consistency 7a pressed. The press plate 17 is then removed while the knife frame 18 remains. During the rest When the basket is lifted, the cake is pressed against the knives and through them into Divided parts of the same size. The cheese blocks formed in this way can then be in its upper layer permanent basket, as they are now at a suitable height above the bottom of the container 1, can be brought to the cheese molds for further treatment without difficulty. The one after pre-pressing The whey remaining in the container 1 is allowed to run out through the valve 2.

The device according to the invention is expediently placed under the cheese pan used for curdling brought that the cheese mass and the whey from the cheese vat run slightly down into the container 1 or can be shoveled. Of course, the device according to the invention can also be used alongside or in the same Height with or higher than the cheese pan, but in this case the Cheese mass and the whey are pumped from the cheese vat to the container 1 in a suitable manner. Finally, there is also a possibility of designing the container 1 in such a way that it also replaces the cheese vat can be used and then completely replaced. Of course, each block of cheese can be used if necessary be further divided into two or more equal parts, which can be done by the obtained by the division with the knife frame 18 blocks of cheese before removal from the Device can be cut with the help of a cutting wire, which runs horizontally through the cheese blocks along a or several guides are guided, which are arranged at a suitable height and parallel to the bottom 5 of the basket are.
