Enhance Vat Cleaning

Milk vat


Cleaning the vat is not a place to skimp on water but it may be worth checking that your current cleaning regime matches the manufacturer’s recommendations.

As a general guide, the amount of hot water required for effective cleaning is 1-3% of the milk vat’s storage capacity, although the design of the vat makes a big difference and there is a poor relationship between size and water use.  The number of cycles per wash and the temperature of each cycle will also affect the total volume of water required.

The newer spray heads ($150-$400) and pumps ($1,000 - $2,000) increase kinetic energy and can sometimes reduce water use.

Systems that re-use the detergent wash fluids are available but the costs of maintaining their temperature can be high. 

Tips on Getting the Best Result

Check and clean spray heads periodically.  Use correct chemicals.  Retro-fitting vats with new spray heads can be tricky – seek professional advice. 

Pros and Cons

New spray head systems can usually be retrofitted to vats with sealed lids, older vat designs may leak.
