A device for cooling milk on livestock farms [1] , which includes a thermally insulated tank, valve, control unit, truboprovodov system, the level sensor installed in the insulated tank.

The closest in technical essence of the present invention is a device for cooling milk [2] , containing the heat-insulated tank, valve, water pump, level sensor, mounted on the pipe connecting the water supply system with the lower part of thermally insulated housing, control unit, water pump.

The disadvantages of this setup are: insufficient speed numerazione ice; insufficient number zamorajivanie ice; the high cost of living labor.

The aim of the invention is to improve the quality zamorajivanie ice and increase the speed of the process namori - tion.

As a result of use of the invention significantly improves the speed of the process numerazione and ice quality, and reduced labor costs.

The above technical result is achieved by the fact that the installation, vklyuchitel, mounted on the pipe connecting the water supply system with a heat-insulated tank, put two pairs of electrodes are vertically arranged in the heat-insulated tank and connected in series by block comparison, rectifier and amplifier, and the electrodes are designed in the form of two pairs of plates, one of which is in the form of a continuous electrically conductive plates, and the other in the form of alternating conductive and isolated areas, the conductive area of one plate is located at the level of the Central part of the isolated sections of the second plate, with the electrodes connected to the Comparer.

The quality and speed of numerazione ice rise due to the fact that in the process of numerazione diagram of the proposed setup allows you to continuously measure and compare the electrical conductivity of the ice layer and water applied to the frosting. The conductivity of the ice and water are measured by using a pair of electrodes, made in the form of a continuous electrically conductive plates, and the electrical conductivity of ice is measured with the help of another pair of electrodes is made in the form of alternating conductive and isolated areas. Electrode design does not allow a layer of water at the same time to close provodyaschego, balanced block comparison, when this signal to the control unit for supplying another portion of supercooled water. Thus in the ice layer will not remain inclusions of water, reducing its quality, and at the same time, the water in the frosting will be supplied with a maximum speed of ensuring a high quality of ice.

Speed numerazione ice is due to the fact that supercooled water is pumped with adjustable drive, which enables you to evenly spray the water on amorgianos surface.

The electrodes are connected to the comparing device, which, through the rectifier and amplifier electrically connected with the control unit, the inputs of which are connected with level sensors located in the recessed portion of the ice Bank.

The first output control unit is connected with the valve, and the second output via adjustable actuator - water pump, located in the insulated recessed portion of the ice Bank, through which the feed pipe is connected with the valve.

Comparing the device is made, for example, in the form of two coils connected in opposite-consistently and located on the General magnetophon is an example of a water pump.

The device is equipped with a level indicator of ice, made for example in the form of a milliammeter, which through open contacts connected to the pair of electrodes, made in the form of alternating conductive and isolated areas.

The drawing shows the proposed installation.

The installation includes a thermally insulated tank 1, truboprovodov system (tube 2), the sensor level 3, unit 4 management, water pump 5 and the valve 6 mounted on the pipe 2 connecting the water supply system with a heat-insulated tank 1; two pairs of electrodes are vertically arranged in the heat-insulated water tank 1 and connected in series with the block 7 of comparison, the rectifier 8 and the amplifier 9, the output of the latter is connected to one input of the control unit 4, the other input connected to the sensor 3 level, and the output from the actuator 10 of the water pump 5 and the valve 6, moreover, the electrodes are designed in the form of two pairs of plates, one of which is in the form of a continuous electrically conductive plates 11, and the other pair is in the form of alternating conductive and isolated areas 12, the conductive area of one plate is located at the level of the Central part of the isolated sections of the second plate, when it is ice, performed, for example, in the form of a milliammeter connected to the pair of electrodes, made in the form of alternating conductive and isolated sections 12 through open contacts 14.

The device operates as follows.

Water from the water system of the farm is fed through a controlled valve 6 in the recessed portion of the insulated tank 1, where the pre-cooled. Upon reaching the upper level sensor 3 level via the control unit 4 supplies the signal controlled valve 6 to stop the flow of water. Capacity recessed portion corresponds to one layer zamorajivanie ice. The first layer of ice covered in the manual mode. Then applied a second layer of water and enables the circuit controlling namoroka ice. This scheme works as follows. When the voltage supply to the pair of electrodes (plates, sections 11 and 12) is an electric current whose magnitude depends on the resistance of the interelectrode space. In the presence of the water layer resistance between the electrodes (11) an order of magnitude smaller than that between the electrodes (12), because the layer of water is not locking alternating conductive plates. Due to the difference of the currents flowing in the windings of the block 7 crowningshield difference current of the currents. This voltage is rectified by the rectifier 8 and is supplied to the amplifier 9, where it is amplified and fed to the control unit 4.

During freezing the water layer resistance between the pairs of electrodes (11 and 12) will be close. As a result, the voltage on the control winding will be close to zero. In this case, the output of the rectifier 8, the voltage is also zero. When the control unit 4 includes a water pump 5 for pumping chilled water namoroka. When turning on the water pump 5, the control unit 4 adjusts its performance for uniform distribution of water on the ice surface, which promotes uniform ice buildup in significant negative environmental temperatures. When the water level in the underground part of the tank 1 falls below the sensor 3 of the lower level, the water in the tank 1 is stopped, and offer controlled valve 6. Then the cycle repeats.

As a pointer array level ice is used, the measuring device. When pressing the switching contacts 14 on the pointer 13 will receive a signal that corresponds to the thickness of zamorajivanie ice. Thus you can determine the number nevrogennogo ice. This Polo is range signal to switch on the water pump 5 for supplying water to namoroka.
