product supply 3, the device 4 for the compaction of flour, which is located in the measuring channel with the ability to move in the direction of the optical axis of the measuring device and can be made in the form of a piston 5 or with a concave working surface 6 with an electric or pneumatic drive (pneumatic cylinder) 7. The product to be pressed is pressed against the measuring device 1 by means of a piston compaction device 4, the meal is compacted and the air inclusions are eliminated at the same time, since air escapes from the high pressure area. The pressing area is shaded in order to show that an absolutely uniform surface is formed for measurement, which can be maintained until the measurement process is completed. The arrows indicate that the flour cannot leave the pressing area, i.e. volume held under pressure. The pressure region spreads in the form of a cone and is formed on the basis of the mechanics of granular bodies. When the measurement is completed, the entire product being measured is extended. A new measurement can be repeated at any time (or cyclically).
To measurement channel 2, through which the main product stream flows and to which the drain is connected - from the line or bypass 8, which at the end through the pipe 9 again goes to the main line 10. The bypass section of line 11 is the input connection between the main line 10 and bypass B. Measuring channel 2 has an upper pressing space 12, as well as a vibrating outlet 13, in which there can be
a vibrator 14, the outer contours of which form an adjustable dosing gap with the housing 15 of the vibrating outlet 13 from below. In this case, the vibrator 14 is suspended in the housing 15 in the form of a tandem. In the pressing space 12, a fixture 4 is installed in its lower third, for cycling the grinding of grinding, as well as a measuring fixture 1. The pressing piston 5 has a concave pressing surface 6 in the form of a spoon. The measuring device 1 is optics 16
as well as computing electronics 17, 15 lindrom 7, which to ensure
from which the signals are transmitted further to the microcomputer 18 and the microcomputer 19, the microcomputer 18 can be directly connected to the printer 20. The instruction block for the entire measuring channel 2 is formed by the microcomputer 18, which, via computer electronics I7, controls the vibrator 14 and the pneumatic cylinder 7 of the piston 5 and simultaneously what it seals the measured
a cut out measuring device 1 prepares and introduces a measurement phase.
A compaction device 5 for compaction of a measurable product consists of two inflatable air cushions 21 placed along the measuring channel, which are located within the measuring channel 2. Both air cushions 21 are powered by pneumatic lines 22, also through a pneumatic pressure sensor 23 and controlled by a control head 24, which is controlled by the microcomputer 18 via the control electric cable 25, as well as the vibrator 14. The latter also controls the entire course of the measurements.
FIG. Figure 9 shows a variant of the mechanical device dp compaction of the measured product in the area of the measuring device 1, in which the measuring channel differs from that shown in fig. 5 and 7. In the embodiments of FIGS. 6, 7 and 9, the pressing space 12 is made in the form of a tubular body. When performed according to FIG. 6 and 9, press space 12 expands downwards. The cross section of the measuring section, which is formed by the compression space, therefore increases in a downward direction. Due to this, not only is the effect of product friction reduced
against the wall, but a possible interfering action of mechanical actions embedded in the pressing space can also be eliminated. A device for compacting a measured product according to FIG. 9 consists of a spoon, which is complete with the possibility of rotation around the horizontal axis 26 on the holder 27 of the spoon within the measuring section (i.e., press-button space). The holder 27 of the spoon through the axis 26 is firmly connected to the lever 28 and is driven into motion by the pneumatic requirement of rotation by means of the finger 29 pivotally on the supporting portion 30 fixed on the measuring portion. Thus, the spoon can perform a movement corresponding to the movement of the concave pressure surface in FIG. 5. When measuring, the spoon b with the described mechanism moves to the measuring device 1, following 5

the product in front of the measuring device I, After the measurement is completed using control systems, the spoon is again removed from the measuring
0 of the tool 1, then the vibrator 14 is turned on and the compacted product is again loosened and brought down.
Fig. 10 shows a variant using a metering screw or a feed screw 31. Measuring device 1 as well as device 4 for impregnation of the measured product is made according to fig 5 or with a spoon, as shown in fig. 9, the feed screw 31 by means (not shown) controlled so that the measuring section 32 during normal operation is continuously filled with products in which there is no
5 air. The measuring device 1, the device 4 for compacting the product, as well as the driving motor 33 for the feeding screw 31, are controlled from a microcomputer 18,
0 Feed screw 31 may have
(figs. 11 and 12) in the outlet region, the fixture 34, which protects against backflow, which by means of the drive means 35 in a certain tact and with the necessary force can move to or from the opening 36. The drive motor 33 and the drive means 35 as well as the fixture 34 for protection against
back pressure is so consistent with each other that when measured in a product a certain pressure is maintained. The feed screw 31 operates against pressure. In preparation for the measurement, this pressure is repeated, device 4 (Fig. 12) is also set in motion to seal the measured product, and then measured values are obtained from the measuring device 1. At the end of the measurement, the opening 36 is released and by turning on the driving motor 33, the product is continuously passing through again.
FIG. 13 is a diagram of an apparatus used to control and control the mixing of products for the production of flour, cereals and dunst in one mill;
For the varieties of the product laid in each case by the continuous measuring instrument 37 with the attached electronic unit 38, the control through the calculator 39 establishes the Tpe6yef i.e., quantitative ratios. The mixture of the product of the total feed screw 40 is fed to the mill or to the roller machines 41 and the sowing plants 42. The obtained flour in the measuring section 43 is measured in relation to its constituents, for example the protein content, and the values obtained through the control line 44 enter TC to the calculator 39. If the calculator 39 determines that there is a deviation from the predetermined value of the protein content, it automatically adjusts the mixture (and taking into account the time delay) to those tfp, until the actual value of the protein content is coincides with a predetermined.
The amount of raw product is continuously measured by the automatic quantity regulator 45 and, in accordance with a given value, the required amount of water is metered and added through the water metering unit 46. The raw material and water are mixed in an intensive humidifier 47, milled in roller machines 41
Flour is seeded in flat screens, and composite substances are measured, in this case, the water content in flour at measuring section 43. The measured signal of the infrared measuring device 1 is fed to the calculator 39 along the control line, which compares the actual value with the target value and according to the set value. in the program memory, by appropriately changing the amount of water added by the water dispenser 46, it corrects for deviations.
