When it comes to powdered milk production, Grundfos' range of sanitary pumps offers excellent solutions to every process step. From milk reception to packing, the handling is carried out with great precision and care, ensuring that your final product is one of high quality.
Milk reception: In by far the majority of dairies the milk is transported from the milk tanker into the tanks using a single-stage centrifugal pump. If higher pressure is required, a multi-stage pump is available. In order to completely empty the milk tanker, a single-stage self-priming pump, creating vacuum on its own, can be supplied.
Milk treatment: During the treatment process single-stage centrifugal pumps transport the milk from one tank to the next, while an end-suction pump enables quick heating of the milk to kill all bacteria – and an equally quick cooling process. A speedy pasteurisation is crucial in order to protect the flavour of the milk.
Process: In powdered milk production it is all about prolonging shelf life. The milk is pasteurised using single-stage centrifugal pumps and then transported to sealed tanks where the evaporator process takes place. Grundfos' multi-stage centrifugal pumps have been designed to create high pressure, ensuring that the milk is evaporated to dryness. Throughout the evaporating process the increasingly viscous liquid is carefully handled by lobe pumps.
|The pressure in the evaporator tanks must be very high for the milk to dry.||Grundfos’ sanitary multistage centrifugal pump ensures a constant high pressure in the tank.|
|In the production of powdered milk the liquid becomes increasingly viscous.||Grundfos' lobe pumps have been developed specially to handle even extremely viscous liquid.|
|In order to protect the flavour of the milk – and consequently ensure high quality in the finished product – a very quick heating and cooling process is crucial.||Grundfos’ centrifugal end-suction pump enables efficient pasteurisation of the milk to kill all bacteria.|
|Particularly in powdered milk production, it is important to eliminate the risk of milk sticking to the inside of the evaporator tank, consequently leaving bacteria to develop.||The inside surfaces of Grundfos sanitary pumps can be customised to match the requirement of the specific application. If need be, the surface can be mirror-like.|
|Maximum hygiene is essential in all dairies.||All Grundfos' sanitary pumps are CIP- compatible, allowing tanks, pipes and process lines to be efficiently cleaned without having to dismantle the equipment. Precise dosing pumps speed up the CIP-process by adding only the necessary detergent, consequently reducing the flushing of the system. Every CIP- system is followed by a single-stage self-priming pump that removes every last drop of detergent in tanks and pipes by circulating rinsing water. A CIP-system can also be applied to the milk tanker to allow easy and 100% reliable cleaning of the inside of the tank. C: In dairies it can be necessary to adjust the production speed to match the packing speed.|
|In dairies it can be necessary to adjust the production speed to match the packing speed.||Grundfos offers advanced E-solutions that will automatically adjust the speed of the pumps, ensuring that the packing process is able to keep up with the production itself. Safe communication with Profibus is possible.|
- All Grundfos’ sanitary pumps carry the EHEDG certificate. Certain models also carry the 3A certificate.
- Choose SiC/SiC mechanical shaft seals if the oxidizing disinfection agents could potentially cause corrosion.
