Definitions

• the object of this invention is an apparatus for the production of soft cheese, such as cheese bread, comprising a cheese vat for curdling milk, cheese moulds that are filled with a mass of cheese provided from the cheese vat, and at least one baker for baking the mass of cheese in the moulds, the baker comprising heating means and a base below them for carrying the moulds.
• a mass of cheese curdled from a cheese vat is discharged from the vat and compressed into a hoop on a sheet functioning as a mould.
• the sheet with several moulds on it is transferred into a baker in which the upper surface of the cheese is baked.
• the cheeses are turned upside down and the other side thereof is baked in the same or in a different baker.
• the ready-baked cheese breads are placed on shelves to cool.
• the space required by the arrangement and the energy consumption it would be desirable that the heating means could be placed as near to the upper surface of the cheese as possible.
• the heating means must be placed too far away from the cheese in these respects since the sheet would otherwise heat so much that it would lose its planar shape. Unevenness of a sheet forms slits between the hoop and the sheet, through which slits the whey contained in the mass of cheese may leak to the outside of the hoop where it burns to the sheet. The whey burnt to the sheet is extremely difficult to remove therefrom.
• the aim of this invention is to provide an apparatus enabling placing of the heating means nearer to the upper surface of the cheese as before. It is characteristic of the apparatus according to the inven ⁇ tion that the base carrying the cheese moulds is situ ⁇ ated at the heating means below a water surface.
• the base carrying the cheese moulds When the base carrying the cheese moulds is placed below the water surface at the bakers, it is largely protected from the heat radiation of the heating means, wherefore the heating means can be placed nearer to the cheese than before and/or the carrying base can be constructed to be lighter than before. Owing to the nearness of the heating means, the baking of the cheese speeds up, the apparatus does not need as much space, and the energy consumption decreases.
• a baker can be constructed such that below the heating means is a water basin containing cooling water with which the cheese moulds are in con- tact when they are in the baker. Owing to the fact that the lower surface of the cheese moulds is in contact with the cooling water, the lower surface of the cheese, which in the later baking step is already ready-baked, cools already during the later baking step, whereby the time needed for cooling the cheese in the shelf unit becomes shorter and the size of the shelf unit can be decreased.
• the arrangement according to the invention is carried out such that at the baker the conveyor passes down below the water surface of the water basin situated below the heating means.
• the carrying base is preferably situated from 0.1 to 2 cm, particularly advantageously about 1 cm, below the water surface, whereby the water provides significant protection for the carrying base and the cheese moulds are sufficiently deep down in the water to cause effective cooling of the lower surface of the cheese.
• Figure 1 illustrates the principle features of an apparatus for the production of cheese
• Figure 2 illustrates likewise the principle features of a baker
• Figure 3 shows a cheese mould in the baker.
• Figure 1 shows a cheese vat 1 with a blender 2 therein.
• the cheese vat contains heated pasteurized milk, rennet and salt.
• the mass of curdled cheese and the whey flow along a pipe 3 to a wire conveyor 4, where most of the whey is discharged through the wire.
• the mass of cheese still containing whey falls from the conveyor 4 into a cheese production tower 5 through the inlet opening thereof, which is also the upper end of the essentially upright tower.
• the mass of cheese is compressed by gravity and whey transfers from the mass of cheese to the outside of the tower through a slit 6 in the wall thereof.
• a guillotine 7 by means of which plate-like blocks can be severed from the pillar of cheese formed in the tower, the blocks falling into a round bowl-shaped mould 8 below the cheese production tower.
• the mould can be placed on an endless conveyor 9 which conveys the moulds under two bakers 10 and 11.
• the cheese breads are turned between the bakers at a point 12.
• a shelf unit 13 At the discharge end of the conveyor 9 is a shelf unit 13 in which the ready- baked cheese breads still in the moulds are placed to cool.
• the structure of the bakers 10, 11 is presented in greater detail in Figure 2.
• the bakers comprise at least one preferably electrically driven heating means 14, the heat radiation thereof being directed downward, and a water basin 15 below the heating means 14.
• An inlet pipe 16 and a discharge pipe 17 open into the basin to feed cooling water into the basin and to dis ⁇ charge it therefrom.
• the flexible conveyor 9 passes down below a water surface 18 to the bottom of the basin or the vicinity thereof.
• the distance between the conveyor and the water surface is preferably from 0.1 to 2 cm, particularly advantageously about 1 cm. This means that the lower part of the cheese moulds 8 carried by the conveyor 9 is surrounded by cooling water. It should be noted that the conveyor 9 must be so close to the water surface 18 that the moulds 8 move with the conveyor. Furthermore, the upper edge of the moulds must be above the water surface since it is desirable that the cheese does not become in contact with the water.
• Figure 3 shows a cheese bread disc 19 in the mould 8.
• the apparatus according to the invention operates in the following manner.
• the cheese fallen from they wire 4 into the tower 5 is compressed by gravity and moves downward in the tower.
• each part of the cheese pillar passes several times the whey removal slit 6 at which whey leaks to the outside of the tower.
• cheese is produced in a continuous process.
• the mould 8 arrives at the point 12 where the cheese is turned upside down either by hand or with an apparatus. Thereafter the mould arrives at the second baker 11, which has the same structure as the baker 10. The surface baked at the baker 10 is now facing downward in the mould and is cooled by the cooling water such that after the baking its temperature is not more than about +15°C. The moulds containing a cheese bread baked on both sides are placed in the shelf unit 13 to cool.
• the apparatus according to the invention is not restricted to the working example described above but can be modified within the limits of the attached claims.
• the conveyor 9 can be replaced with another carrying base, such as a sheet. If the cheese and/or water are such that the cheeses can be in contact with the water, the moulds 8 need not be bowl-shaped.
• the carrying base 9 need not be situated above the water surface between the heating means 14 but it can be entirely below the water surface.
