New technology reduces milk
cooling costs
Correct cooling and storage of milk is of vital importance to ensure milk
quality is maintained until collection, ensuring maximum price can be
Many factors contribute to the optimum care of milk,
from tank construction to cooling technology used, to the
washing and control systems. Installation and running costs
also need to be seriously considered when selecting a tank.
A recent study by Teagasc researchers on dozens of Irish
farms found that over half the electricity bill was accounted
for by milk cooling and water heating. Dairy farmers are
constantly looking at ways of increasing profitability and it
is evident that this is an area which can be improved.
Over the past 10 years, the SwiftCool range of milk cooling
and water heating equipment from Dairymaster has
transformed industry expectations. The milk tank is now
seen as an investment for the future of milk quality and
energy efficiency. At farm level, typical savings over the
expected lifetime of the equipment would be in excess of
40,000 for a 100-cow herd (based on farm data published
by Teagasc in the Journal of Dairy Science).
Having developed a milk tank to keep milk cool with
minimal energy use, Dairymaster turned its attention to the
objective of cooling milk as efficiently as possible from 35C
out of the cow to 4C in the milk tank. In order to further
research and better understand the cooling process, the
company invested in a climatic evaluation laboratory at its
global headquarters in Co. Kerry. This facility enabled the
