Cleaning machines for milk cooling equipment

Automatic cleaning machine AWE

Closed milk cooling tanks are cleaned after unloading by a fully automatic cleaning system. Here all milk residues are completely removed from the tank. The tank is cleaned in several washes with cold and hot water and detergent.

ETSCHEID has developed reliable and cost AWE cleaning machines that can be used as original equipment on new milk cooling tanks and the exchange or conversion of used equipment. The unit is robust and insensitive to different operating conditions, such as the water quality or voltage fluctuations.

The cleaning machine AWE consists of a combined cooling and cleaning board with circulation pump and detergent flow. The machine is integrated into a stainless steel case and therefore optimally protected against dirt and splashing.

The thermostat can be switched and can be set to two refrigeration temperatures. The board has a manual stirring function, and a subsequent agitation. Emergency cooling or manual operation of the compressor and the agitator is optional.

Optionally, the device with a pass-heater (8.4 kW) are equipped with adjustable thermostat for heating and dry-cleaning water.

Cleaning programs

The cleaning machine AWE has 5 cleaning programs.

  1. Short pre-rinse with mixed water (hot and cold). Several pre-rinse cycles adjustable!
  2. Main wash with warm water and alkaline detergent flow through peristaltic pumps, optional heating.
  3. Intermediate rinse with cold water.
  4. Main wash with cold water and acid detergent (optional heating switchable).
  5. Final rinse with cold water (multiple choice).

Operation and programming is done from the outside without opening the cabinet. If case of service it is easy to replace the board because of the use of simple cable connectors.
