<p>PCT No. PCT/FI86/00018 Sec. 371 Date Sep. 18, 1986 Sec. 102(e) Date Sep. 18, 1986 PCT Filed Feb. 14, 1986 PCT Pub. No. WO86/04828 PCT Pub. Date Aug. 28, 1986.The invention concerns a procedure and a means for use in pumping and volumetry of foodstuff liquids. According to an embodiment of the invention, the foodstuff liquid is conducted through a suction pipe (14) or a suction tube into an air separator (16) and from the air separator (16) through a pumping device (23) further onwards. The air present among the foodstuff liquid is separated in the air separator (16) with the aid of vacuum in that a vacuum device (20) is activated when the pressure prevailing in the air separator (16) is higher than a preset value. The flow of the foodstuff liquid to the air separator (16) is controlled with a control device (15) disposed in the suction pipe (14), this control device being controlled in accordance with the level of the foodstuff liquid in the air separator (16). When the level of the foodstuff liquid reaches in the air separator (16) an upper level (A) dependent on the magnitude of the flow the control device (15) has been arranged to be fully closed, and when the level of the foodstuff liquid reaches in the air separator (16) a lower level (B) dependent on the magnitude of the flow the control device (15) has been arranged to be fully open, and vice versa. When the level of the foodstuff liquid is rising in the air separator (16) between said upper level (A) and said lower level (B) the control device (15) has been arranged to reduce, and when the level is falling to increase, the foodstuff liquid flow entering the air separator (16).</p> |
