Milk cooling solutions for VMS

In conventional milking systems the milk tank is filled to ten percent of its capacity before starting to cool the milk.

This means in conventional 6 000 litre milk cooling tank for example, 600 litres of milk are needed before cooling can start without freezing the milk. Freezing milk severely damages its protein structure, affecting both its taste and appearance. This reduction in quality naturally reduces milk income.

DeLaval milk cooling tanks are designed to start automatic cooling when the tank is five percent full. But with average flow rates of 2 litres per minute in robotic milking systems, it would take more than three hours to reach that minimum level for cooling, or even longer in larger milk tanks. This time frame is too long: milk quality cannot be preserved by using conventional cooling systems for milk being delivered via automatic milking.

Automatic milking has brought a new set of challenges for cooling, since it delivers milk to the tank at irregular intervals and flow levels. On top of that, consider what happens when the main storage tank has been emptied by the dairy and then requires cleaning, while the milking stations continue to milk cows on demand.

DeLaval has responded to the challenge, developing cooling systems to work with DeLaval VMS and ensure that milk quality is preserved and best utilization of DeLaval VMS assured:

Store and protect your milk:

1. Range of vertical and horizontal cooling tanks DXCR/DXCE/DXCEM and DX3S

2. DeLaval VMS – DeLaval cleaning and control unit CCU communication – information about milk amount is sent to tank constantly. Tank is sending status (including temperature of milk, cooling or cleaning mode etc.) and abnormal situation (e.g too long cooling tank, low cleaning water temperature) back to DeLaval VMS. Farmer knows when situation needs his or serviceman attention

Cool your milk:

1. DeLaval compact chiller CWC – provides source of cold water to instantly cool the milk even before it reaches tank or buffer

2. DeLaval adaptive flow controlled cooling AFCC. This unique cooling solution for DeLaval voluntary milking system VMS is based on our patented concept of flow controlled cooling. DeLaval VMS notifies the cooling tank of the volume of milk delivered to it, on a real time basis. The tank then adjusts its cooling capacity to suit that milk volume.

3. DeLaval flow control cooling FCC. Simpler version of adaptive FCC utilizing standard condensing units.

Buffer milk:

1. DeLaval buffer vessel BVV/DBV – enabling 24/7 operation of DeLaval VMS by allowing milking while tank is not available due to milk pick-up and cleaning

Reduce electrical energy bills and environmental burden while cooling your milk:

2. DeLaval pre-cooling solution – uses water that cows drink to take up to 50% of the heat from the milk reducing environmental burden of cooling and energy bills.
