Description

The bench GPA PA0 allows the study of three stages pasteurization. The liquid to be treated (fruit juice, milk…) is sent into the tubular exchanger using a pump. In the exchanger circulate heating water against the current what will heat up the liquid to be pasteurized by thermal transfer.
A the exchanger exit, the juice leaves pasteurized

The robust design of this device makes it suitable for use in schools.
The equipment is set up on an Anodized aluminium frame on casters wheels. This gives it great strength and a flexibility of integration into your premises.
The manufacture of this equipment complies with the European standard for machinery manufacturing.

The bench includes a power supply box that complies with European electrical standards with a standby power disconnector, white voltage presence light, emergency stop button, earthing connection and differential protection.
A 7-inch colour touchscreen displays the temperature values at the various measuring points.
The bench is installed on a square stainless steel profile frame.
