Definitions

• the invention relates to a process for converting deep-frozen, large blocks of butter into butter with the desired water content, with the following steps and with the addition of water:
• Barrels are usually horizontal-cylindrical, vertical-double-conical or vertical-cylindrical with an attached cone. The desired amount of water was added in the butter maker.
• the invention is based on the object of being able to carry out the reworking of frozen blocks of butter into butter with the desired water content in a more rational and less personnel-intensive manner.
• the method according to the invention is characterized in that at least a large part of the water is metered into the butter chopper, that the butter chips are then conveyed through a vacuum zone, and that the butter mass is then kneaded in a roller kneader, while it is continuously conveyed under pressure through the roller kneader with a high-performance butter pump.
• the process can be carried out fully continuously or at least continuously from behind a butter pan downstream of the butter chopper.
• the amount of water added is expediently so large that the legally permissible maximum water content is used as completely as possible. All of the water is preferably metered into the butter chopper, which is very precisely possible there. However, it is also possible to meter in part of the water in the vacuum zone and / or in the roller kneader. Alternatively, it is also possible to concentrate the water addition entirely on the vacuum zone and / or the roller kneader.
• the butter mass is preferably pressed in succession through several roller kneader sections or segments, each of which can have its own roller arrangements or roller pairs.
• a roller kneader with several sections a plurality of individual roller kneaders connected in series can also be used.
• the butter blocks are thawed to such an extent that the butter chips in the butter chopper reach a temperature which is particularly suitable for water absorption, in particular about 8'C.
• a particularly suitable temperature after thawing is the range from 6 to 8 ⁇ C. - -
• the invention further relates to a system for converting deep-frozen, large blocks of butter into butter with the desired water content, comprising:
• the butter chopper has a water metering device; that a vacuum zone is provided between the butter cutter and the butter maker; - ⁇ -
• a continuously working roller kneader is provided as a butter maker; and that a high-performance butter pump is provided as the first butter pump, which conveys the butter continuously under pressure through the roller kneader.
• the high-performance butter pump is preferably a butter pump built according to the displacement pump principle, in particular a gear pump or a rotary vane pump.
• a rotary lobe butter pump is described in more detail below.
• the roller kneader preferably has rollers arranged in pairs, which - roughly speaking - have an essentially square cross section and grooves running longitudinally on the outside.
• the butter chopper can be designed in a horizontal or vertical construction.
• FIG. 2 shows a high-performance butter pump in a schematic cross section according to A-A or according to C-C in FIG. 1;
• FIG. 3 shows a roller kneader in a schematic cross section according to B-B in FIG. 1.
• the butter chopper 1 shows a butter chopper 1 with a water metering device 10, which can have one or more spray nozzles 11.
• the butter chopper 1 works in a butter screw pan 2.
• a butter pump 3 At the exit of the butter screw pan 2 there is a butter pump 3, which is designed like the butter pump 5 described below.
• the butter chip mass can be conveyed into a vacuum zone 4, which can be implemented, for example, by a closed butter screw pan.
• a high-performance butter pump 5 sits between the vacuum zone 4 and a roller kneader 6 having several sections or segments.
• the roller kneader 6 has two kneading rollers 15 running axially in its housing (cf. FIG. 3), which are driven by an adjusting gear motor 7 .
• Each section of the roller kneader 6 has its own pair of rollers, but the rollers of the sections have a drive connection with one another.
• Such a number of roller kneader sections is selected as is necessary for ensuring the throughput of the plant in question in order to ensure a proper work result.
• the roller kneader 8 At the outlet of the roller kneader 8 there is a further butter pump 8, with which the finished kneaded butter mass is conveyed to a shaping machine or shaping and packaging machine, not shown.
• the butter pump 8 can also be designed like the butter pump 5.
• the output butter blocks usually have a mass of about 25 kg and before thawing a temperature of about -10 C.
• the ⁇ to be produced butter portions are for example, 0.5 kg or 0.25 kg.
• FIG. 2 a schematic cross section of the 'high-butter pump 5 in the manner of an Eaton pump displays a substantially oval-shaped housing 12 in which two rotating pistons 13 rotating in opposite directions.
• the rotary pistons 13 have a three-wing cross-sectional shape with rounded wing ends and concavely indented areas between the wings.
• the rotary pistons 13 rotate without direct, mutual contact, but with only a small gap between them.
• the rotary piston rotation alternately creates smaller and larger spaces in the high-performance butter pump 5, as a result of which the butter contained is conveyed under pressure. Because of the geometry of the housing 12 and the rotary pistons 13, reference is expressly made to FIG. 2.
• FIG. 3 shows an oval housing 14 and the two oppositely rotating rollers 15 contained therein one above the other.
• the rollers 15 have - roughly speaking - an essentially square cross section, the square sides not being flat are, but have axially longitudinal grooves 16. Because of the geometric shape of the rollers 16, reference is expressly made to FIG. 3.
