MACHINE DESCRIPTION
The MIXPASTO 60/120 PASTEURISER machine pasteurises mixes for ice cream by heating the products at
85° for high pasteurisation and break-down everything in the least possible time at 4°C.
The mix must then be preserved at 4°C to 6°C for the entire period of use that can be at a maximum of 72h.
The products are mixed during the process by means of a stirrer in tank that, based on the stirrer speeds
and shapes, favours the thermal exchange, gives consistency and different softness to the finished products.
The pasteurisation temperature can be lowered to 65°C depending on the ingredients, proportionally
extending the maintenance times to the temperature (low pasteurisation).
The machine consists of a 60 or 120 l tank protected by a transparent lid. The tank contains a motor-driven
stirrer and a pick-up cock on the bottom.
The machine heats the product through the circulation of a water and glycol mix heated at an adequate
temperature in a copper coil wrapped on the tank's outer surface. Cooling is through the circulation of freon
gas in another copper coil also wrapped on the tank's outer surface.
The water and glycol mix is heated by an armoured heater in a boiler and is pushed by a pump in the closed
circuit.
The water and glycol mix is pressurised in the circuit having an expansion vessel and safety valve (max 0.7
bar). The glycol temperature is electronically controlled by a safety thermostat that interrupts the heaters'
power supply if a safety temperature is exceeded (max 120°C).
Opening the lid interrupts stirring, isolating the motor's power supply, the heating/cooling and the glycol
circulation. The machine is ready to restart when the lid is closed. Opening the lid causes one or more
magnets to move away from the relative magnetic sensor that, in turn, switches off the relay and relative
contactors.

OPERATORS' QUALIFICATION
The operators and maintenance technicians in charge of machine functioning or maintenance must have the
specific professional requirements for every provided operation.
They must be trained and aware of the tasks entrusted to them.
WARNING
All technical modifications affecting the functioning or safety of the machine must only be
