DeLaval has won a EuroTier 2018 silver medal for innovation for its Evanza milking cluster and cartridge.
The DeLaval Evanza milking cluster is the first in the world to utilise a cartridge instead of a liner. It contains a newly designed claw with redesigned TopFlow technology and an easy, quick-connection between the claw and teat-cup.
The new cluster and Evanza cartridge will bring significant benefits to farmers and cows in terms of improvements in performance, animal welfare, service, ergonomics and reliability.
Farms where the Evanza milking cluster and cartridge were tested saw an increase in milk flow of up to 9.3 per cent. The attachment was also better, with reduced total milking time of up to 30 minutes per milking session – a reduction of seven per cent. In addition, teat condition scoring has improved and there was a 50 per cent reduction in service time.
The cartridge change itself is done three times faster than a conventional liner change, saving considerable time and resources.
The new liner is self contained and sealed inside a hard plastic cartridge that simply slots into each cluster shell and makes an air-tight seal into the milk line. Each cartridge has a life span of 5,000 milkings, compared to 2,500 for a conventional liner. The milk tube from the shell to the claw should be changed every year, and the pulsation air lines have a design life of two years.
