Description

 The invention relates to devices for accounting and control of the amount of milk and is intended for the issuance and acceptance of milk at the dairy farms and in farms that process milk. The invention can be used in large dairy plants and food industry enterprises.

 Known milk meters for measuring the amount of milk in pipelines (see AS USSR N1563355, MKI5 A 01 J 7/00 "Turbine flowmeter"). The disadvantages of this device are their inconsistency with existing technology and the difficulty in operation, which is determined by the presence of movable mechanical parts in the milk tract.

 Of the known devices, the closest in technical essence is the "Milk Meter" (see invention bulletin N 25, 1997).

 The milk meter contains a primary transducer made in the form of a smooth pipe made of diamagnetic material, in the walls of which electrodes are coaxially mounted, a transverse magnetic field generator coil, two pairs of contact electrodes, logic and computational units.

 The disadvantage of this milk meter is that it cannot fix the quality indicators of the milk received (such as temperature, density, acidity) and will divide the flows by these characteristics. This leads to organizational and technological difficulties (as payment for milk with different quality indicators is different) and a decrease in the quality of milk, because “pooled” milk acquires the quality of worse milk. Payment of milk only as a function of its volume becomes ineffective.

 The objective of the present invention is the differentiated accounting of milk depending on its qualitative indicators, which will improve the organizational and technological characteristics of the system and the agricultural facility as a whole.

 The above technical result is achieved by the fact that a measuring unit consisting of an upper and lower chambers separated by a partition is hermetically connected to the housing of the primary transducer, the lower chamber being made in the form of a cylindrical pipe, and in the wall separating both chambers there are two calibrated holes connecting them, moreover, the inner walls of the lower chamber between the calibrated holes narrow and form a new calibrated hole, and the upper chamber has a horizontal sealed cover and on it an upper chamber located sensors electrically connected to the computing unit, and on the other side of the primary unit inverter is connected, having two or more pipe branch fitted with the valves remotely actuated electrically connected to the computing unit.

 The invention is illustrated in the drawing, which shows a General view of the device.

 A device for differential metering of milk contains a converter 1, electrode sensors 2, a computing unit 3, a digital indicator 4, and a measuring unit 5, consisting of an upper 6 and a lower 7 chambers separated by a partition 8, is sealed to the housing of the primary transducer 1, the lower chamber 7 made in the form of a cylindrical pipe, and in the partition 8 connecting both chambers, there are two calibrated holes 9 connecting them, and the inner walls of the lower chamber 7 between the calibrated holes 9 are narrowed and Coziness is a new calibrated hole 10, and the upper chamber 6 has a horizontal sealed cover 11, and in the upper chamber 6 there are sensors 12 electrically connected to the computing unit 3, and on the other side of the primary transducer 1, a unit having two or more pipeline branches 13 sec valves 14 mounted thereon with a remote actuator electrically connected to the computing unit 3.

 A device for differential metering of milk works as follows.

 Milk through the cavity of the lower chamber 7 enters the primary Converter 1. In the milk stream crossing the transverse magnetic field, a potential difference is induced on the electrode sensors 2, proportional to the average milk flow rate. The potential difference is supplied to the computing unit 3, and then the processed result on the amount of milk passed through the primary converter is displayed on the digital indicator 4. At the entrance to the lower chamber 7, the pressure increases in front of the calibrated hole 10, and part of the milk flow passes through the calibrated holes 9 and the upper chamber 6, flows into the common flow and enters the primary transducer 1. The intensity of the milk flow through the upper chamber 6 can be controlled by the cross section of the calibrated holes 9. Thus, random flow characteristics: time constant, standard deviation and other characteristics of random parameters can be controlled by the volume of the upper chamber 6, the cross-sectional area of the calibrated holes 9 and be consistent with the dynamic and static characteristics of the sensors and the entire technological system as a whole. On the lid of the chamber 11 in the upper chamber 6 are installed sensors of parameters characterizing the quality of milk or other measured food products. For milk, these are sensors of temperature, electrical conductivity (conductivity), mass fraction of fat, protein, SOMO, the number of somatic cells, acidity (pH), turbidity and other parameters. The sensors are electrically connected to the computing unit and then through amplifying elements - with valves 13 mounted on the pipe branches with a remote actuator 14. Milk with different characteristics is sent to different branches. It is possible to separate the milk flow with different characteristics, pay for milk of various quantities at different rates or to reject low-quality milk, to control the quality of milk in tanks.

 Thus, the proposed device can significantly improve the organizational and technological characteristics of technological systems and economic characteristics of the agricultural object as a whole.
