Definitions
- the invention relates to a grinding and / or polishing machine for cereals, such as rice, wheat or other types of grain, with a grinding and / or polishing rotor or peeling rotor surrounded by a sieve.
- Conventional grinding or polishing machines in particular grinding machines, have an arrangement of sieve segments which are mounted at one circumferential end on an articulated axis, whereas the second circumferential end can be pivoted about this axis in such a way that it fulfills more or less in the cereals to be treated Protrudes into space.
- the purpose of this is to offer increased resistance for the cereals carried by the rotor against the free end of the sieve segment by adjustment radially inward, so that there is friction between the rotor and the cereals or between the cereals among themselves.
- the rotors have a hollow shaft, through the openings of which compressed air is blown into the working area.
- the hollow shaft is connected to a fan / compressed air generator.
- a baffle plate is arranged in front of the exit of the work area, which can be adjusted so that a counterforce opposes the product pressure is judged.
- the counterforce is usually set manually based on experience using a lever mechanism / linkage.
- the invention is based on the object of improving the known construction while avoiding the disadvantages described so that a constant polishing, grinding or peeling of the grain material is achieved.
- the problem is solved with the features of the claims.
- the rotor shaft of the peeling, grinding or polishing machine is designed in a known manner as a hollow shaft with air passage openings on the lateral surface, but the air enters the hollow shaft from both ends. This enables even ventilation of the work area.
- the rotor shaft is advantageously wedge-shaped and the air passage slots are arranged vertically.
- toothed belts to drive the rotor shaft also helps to even out the work performed by the machine. With less energy consumption and almost no slippage, the work performance increases.
- the size of the contact pressure has a direct impact on the degree of peeling, grinding or polishing.
- a pneumatic diaphragm drive with an axially attached force transducer. With this arrangement, a constant contact pressure can be generated on the baffle plate. Previous manual settings of the contact pressure with weights are simulated electro-pneumatically.
- the stopping plate was able to achieve stepless actuation of the stopping plate with small tolerances (narrow band). It is particularly advantageous that the closed position can be kept open even in the event of a power failure.
- the pressure of the product flow on the baffle creates a force that is compared to a counterforce.
- This force generated by the product is immediate, i.e. H. taken up directly by a small spring between the lever mechanism and the force transducer and physically stored during the measuring time of the control.
- the newly calculated force adjustment, due to this system change or inequality of the force relationships, is compensated for via electrical control valves.
- the compressed air in the diaphragm drive and thus the contact pressure on the baffle plate is adjusted until the balance is restored. It is only regulated to a constant contact pressure, which is independent of the bulk density.
- Fig. 1 shows a longitudinal section through a vertical grinder according to the invention
- Fig. 2 shows a schematic cross section of an arrangement for regulating the dynamic pressure
- a vertical grinder 1 has a drive motor 2 for a grinding rotor 4.
- the • overdrive is realized by means of several toothed belts 3.
- a sieve basket 5 is arranged around the grinding rotor 4 and is connected to a suction device 6 for the ground-off bran particles.
- the grinding rotor 4 has conventional grinding tools and elongated air openings in the axial direction.
- the grinding rotor 4 is mounted in a main bearing 7.
- the grinding rotor 4 is designed as a hollow shaft 8 and has an upper air supply 9 and a lower air supply 10.
- the air is supplied via one or two fans, not shown.
- the grinding rotor 4 is slightly wedge-shaped, the diameter above being smaller than below. The wear is more even.
- a vane rotor with fan action can also be provided, which supports the air flow in the working space 14.
- the product outlet 11 is from above.
- the product outlet is closed by a storage plate 12.
- the storage plate 12 is arranged to be vertically movable and its movement is regulated by a diaphragm drive 13.
- the diaphragm drive 13 can also be arranged inside the housing of the vertical grinder 1.
- the rotor can also have polishing or peeling tools and / or be arranged horizontally.
- Electronics 20 monitors and regulates the diaphragm drive 13 with the aid of control valves 21.
- the current contact pressure is absorbed by a force transducer 22 and read into the electronics 20.
- a specific contact pressure can be specified directly on the device (locally) or via a process control system (remotely controlled).
- a pneumatically controlled lever mechanism 23 regulates the product-dependent contact pressure preselected on the electronics 20.
- a small spring 24 absorbs the change in leverage caused by the product. At the same time, the slightly curved spring 24 compensates for the transverse forces on the force transducer 22. If the motor current exceeds a current limit defined in the electronics 20, the lever mechanism 23 is automatically relieved.
