1.7 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.
1.8 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
carried out by the manufacturer's technical personnel or by its officially authorised
technicians. On the contrary, TECHNOGEL SpA declines any liability for changes or damages
that may derive there from.

4.1.2 Operating phases
The MIXPASTO 60/120 is intended for the pasteurisation of mixes for ice cream with heating and cooling
cycles controlled by a micro-processor programmable by the user.
The machine provides the following operative treatment phases for the ice cream mix:
1. pasteurisation
2. emulsifying
3. cooling
4. preservation (maturation)
Emulsifying happens by increasing the stirrer speed in view of the product temperature and by making the
product bang against the metal elements of a specifically designed grid.
The stirrer speeds are pre-set. There are normally 2 speeds set during heating and 2 during cooling; the
speed automatically changes when the mix reaches 55°C, both during heating and during cooling.
The user can request the setting of 3 speeds both during heating and during cooling, from the manufacturer's
Technical Service.
The stirrer speed is further reduced during preservation and it automatically intervenes for 1 minute at
intervals of 20 minutes.
The user can ask the manufacturer's Technical Service to set the functioning times of the stirrer during
preservation differently.
The operator can vary the stirrer speed at any moment by means of the LEFT ARROWS.
The cycle times in the chart of fig. 4.2 refer to laboratory tests with specific products that can differ based on
the type of mix and functioning conditions (environment temperature, water temperature, etc.).

(glycol+water) flows.
The product is loaded from above by lifting the polycarbonate lid; discharge is through the tap located in the
front part of the machine.
The user decides the composition of the mix to be pasteurised: the percentage of the dry part (the density of
the mix) can influence the outcome of the cycle: it must not, however, exceed the limit of 42%.
ATTENTION
The machine must never operate empty!
4.1.3 Use of commands
