Milk reception unit MRU Application Standard design The milk reception unit receives milk and milk products for milk processing plants. The unit deaerates, measures and pumps the product for further treatment. The control cabinet, located above the pump, contains the combined control system and operator interface. The cabinet also houses the electrical circuits and contactors. Working principle The milk reception unit is designed for CIP cleaning. The incoming milk product is introduced tangentially into a vacuum vessel for deaeration. A centrifugal pump removes the liquid from the vessel by suction. Level transmitters in the vessel signal the control system to maintain the optimum liquid level inside the vacuum vessel and to adjust the flow rate of the frequency-controlled pump. Material An electromagnetic flow transmitter measures the flow rate in the pipe downstream from the pump. All parts that come in contact with product are made of stainless steel with semi-bright finish. EPDM rubber seals.
