One of the most labour intensive and time-consuming jobs in dairy milk production is the milking itself, which takes place at least twice a day. Demands have therefore been growing for automatic milking systems to solve this. DeLaval offers the total automatic system, VMS, the Voluntary Milking System.
Due to a continuous low quantity milk flow, 24 hours per day, the VMS system requires an efficient, specially-designed cooling concept, and DeLaval has therefore developed a professional cooling system.
VMS cooling system
The new IN/VMS systems uses a 300 litre receiver, equipped with pump, plate cooler and control unit. The milk flows from the VMS into the receiver tank, is pumped via a plate heat exchanger and cooled before it reaches the main cooling tank. When the main storage tank is emptied, the milk pump is blocked and the milk will stay in the receiver tank during emptying and cleaning of the tank. With this system, the milk is cooled with a P30 Clip-on Plate Cooler.
The VMS milk supply pipes to the cooling tank and instant cooling system are automatically cleaned every eight hours. The storage tank is cleaned by the unit on the tank after the milk is collected.
The ozone layer is a worldwide environmental concern, and the expulsion of chloride-flour-hydrocarbons (CFK’s) from cooling devices has been one of the causes. DeLaval uses environmentally friendly tank insulation materials and refrigerants, and is constantly researching for new ways to reduce any environmental impact of cooling materials.
