    The invention relates to the milling industry.
    The aim of the invention is to improve the quality of the product obtained.
    Figures 1 and 2 depict a device that implements the method in fig. 3 - the same, to control the consumption of grain from silos installed in front of the devices for final cleaning and sorting, and the device for moistening the grain in fig 4 is the same to control the wetting process


    grain, fig.Z - the same, to control the operation of rolling machines,
    The device for controlling the plant for grinding grain contains a processor 1j which, through switches 2, is connected to the corresponding control loops to control the operation of silos, devices for moistening raw materials, roller machines, classifiers and tools for mixing grinding products.
    In addition, the device contains a setting device 3 connected to the unit 4 for controlling the operation of the devices 5 of the plant for grinding grain /
    The processor 1 contains a memory unit 6 with a circuit 7 of predetermined parameters, which is provided with address inputs 8 connected to sensors 9, a setting device 3 and a node 4 for controlling the operation of devices 5 of the unit for grinding grain. Node 10 is a comparison unit, the input of which through line 11 is connected to a device for an actual value (not shown) and a setpoint sensor 12, and an output to a controller; that is connected to a setting device 3 o Control signals outputs memory block 6 is associated with fJ-rx: by the setpoint values of the control loops, which also contain lines 13 for entering new set values, ,, the device also contains a connecting line 14 according to which the device can be turned off when emergency situation, and a connecting line 15 through which node 4 can control the installation in the event of processor failure with memory block 6.
    The device works as follows.

    The outlets of the silos 16 are provided with flow controllers 17, containing a plate 18, which is rotatably mounted and pretensioned relative to the angle deviation.
    The flow of grain entering the plate 18 has a torque on it. The angle of rotation of the plate corresponds to the consumption of grain. The angular deflection of the slab is converted into an electrical signal, which is fed to node 10 via line 11. In addition to TOGO; The node 10 receives, via line 19, a setpoint signal which is supplied from memory unit 6 in the shown position of switch 2. At the other position of switch 2, the setpoint signal is supplied from the setpoint sensor 12.
    By supplying the appropriate setpoint values, any mixture of grain can be fed to the conveying system 20 "
    The process of moistening the grain is controlled as follows.
    In the humidification zone 21, the grain enters via the conveyor 22. In the humidification zone, a device 23 is installed to measure the moisture of the grain, the signal from which S corresponds to the moisture of the grain, via the trunk 24 enters the processor 1 or the auxiliary computer 25, where the amount of water calculated which is necessary to achieve the desired grain moisture. (1b-17%). The required amount of water can be set, for example, as a predetermined value at node 10. If the calculation takes place in process controller 1, the switch is brought to the position shown in Fig. 4. If the predetermined flow rate is manually set by the sample, the switch 2 is turned on in the lower hatched position. If the set value of the water flow is determined in the additional computer 25, then the switch is in the middle position. When calculating the set value of the flow rate, the flow rate of grain, as a rule, is also taken into account,. The flow control unit is provided for node 10, to which a set value is fed through line 19. Actual value goes to node 10
    through line 11, which ends at the measuring instrument inside the valve 26 to control the flow of water. By comparing the actual and setpoint values at node 10, an error signal is determined, which is fed through valve 27 to valve 26. In addition, through line 13 to memory unit 6, a value characterizing the optimum water flow can be supplied.
     moistening the grain enters the silos 28 for otglazhivaniya, and
    silo outputs 28 are controlled by the same 15. This value can be adjusted manually via input 42. It can also be supplied with you closed
    20
    as the silo outlets 16.
    The device also contains rollers 29 and 30 rotatably mounted in housings 31 and 32 fixed to the stopper 33 with bolts 34 and 35. The left roller 29 is additionally equipped with a pin 36. Both housings 31 and 32 are rotatably mounted relative to each other. by means of a guide spindle 37, 25, the entry of qualitative criteria for grain, which, together with electromotoring, for example, the moisture content of grain, with content 38, constitutes the above-mentioned pressing of proteins, and so on, with the installation device. The rotation of the guide spindle 37 leads to a change in the gap between the rollers. In addition to n, a handwheel 39 is also provided, which records the new set points.
    values in block 6 of memory.
    The invention makes it possible to increase the lightness of the flour by 10-12% and reduce the humidity by 15-18%, to increase the switch 2 from the memory block 6 associated with the processor 1.
    To automatically calculate the setpoints, signals 1 from sensors 9 are also supplied to processor 1, which in places 43 and 44 measure temperature (T) and pressure (P). The letter O is also taken into account by the number of rolls used. On highway 13 signals
    by means of which — through the corresponding reduction gear — it is possible to manually rotate the guide spindle.
    At the upper end of the housing 31 a sensor is installed, consisting of a transmitter 40 and a receiver 41. This sensor

    bone during storage by reducing the ability of flour to absorb water by 20-25%.
    supplies an electrical signal corresponding to the distance between its transmitter and receiver. Since the sensor is rigidly connected to the housing 31, the signal supplied by it corresponds simultaneously to the distance between the two rolls.
    The sensor signal as an actual value is fed through trunk 11 to the input of node 10. In the comparison block of node 10, the actual value is compared with a predetermined value received via highway 19. Manually entered through input 42. It can also be supplied with a closed high
