DESCRIPTION:
BRIEF SUMMARY
One of the objects of the present invention is procedure for use in air separation pumping and volumetry of foodstuff liquids, in said procedure the foodstuff liquid being conducted through a suction pipe or suction tube to an air separator and from the air separator through a pumping device and, possibly, a volumetric device into a tank or equivalent, and in said procedure the air present amont the foodstuff liquid being separated in the air separator with the aid of vacuum in that the vacuum device is activated when the pressure prevailing in the air separator exceeds a given preset value.
Another object of the invention is a means for use in air separation pumping and volumetry of foodstuff liquids, said means comprising a suction pipe or suction tube, a control valve, an air separator, provided with a vacuum device for removing the air from the foodstuff liquid in the air separator, and possibly a volumetric device, by this means the foodstuff liquid being drawn from the liquid tank or equivalent into the air separator, whence the foodstuff liquid is conducted through a pumping device and, possibly, a volumetric device towards further use.
One further object of the invention is a procedure for use in air separation pumping and volumetry of foodstuff liquids, in said procedure and foodstuff liquid being conducted through a suction pipe or suction tube to an air separator and from the air separator through a pumping device and, possibly, a volumetric device into a tank or equivalent, and in said procedure the air that is present among the foodstuff liquid being separated in the air separator with the aid of vacuum in that an air venting valve connected to the air separator is activated when the pressure prevailing in the air separator exceeds a given preset value.
Still one object of the invention is a means for use in air separation pumping and volumetry of foodstuff liquids, said means comprising a suction pipe or suction tube, an air separator provided with an air venting valve, a pumping device, and a control valve, by said means the foodstuff liquid being drawn from a liquid tank or equivalent into the air separator, whence the foodstuff liquid is conducted through a pumping device and a control valve towards further use.
Liquid volumetry is carried out, for instance, in milk collection from milk producers taking place with the aid of tank lorries, or when receiving milk in a dair from such tank lorries. The milk is pumped, or allowed to flow, through a pipe system into an air separator tank, in which the milk level rises until a shut-off member, attached to the stem of a float sensing the liquid level, finally closes the air aperture leading to an air venting valve. The closure of the air venting valve may be managed either mechanically or electrically. Hereby an enclosed system is established in the upper part of the air separator tank, in this system a pressure building up gradually, and upon reaching a given value this pressure overcomes the spring force of the directional valve, causing the directional valve to open. The liquid then begins to flow through the apparatus, and the flow goes on until the air present in the liquid stops the operation and escapes through the air venting valve, or until the liquid runs out and nothing but air is pushed out through the pipe.
In the Finnish Pat. No. 64789, among others, is disclosed a volumetric system especially applied to milk collection with the aid of tank lorries from milk producers, in said system the liquid being conducted through a suction pipe or suction tube to an air separator and from the air separator to a volume meter, and in said system being provided a pumping device which has been so disposed in relation to the air separator that the air separator is located on the intake side of the pumping device, the pumping device being controlled with the aid of a control system so that when the liquid level in the air separatorr rises to a first upper level the control system has been arranged to switch the pumping device to low pumping rate, and
