Ice cream machine STAFF Ice system 1959 RHB15/100

The STAFF Ice system RHB15/100 is an electromechanical batch freezer. This combined unit integrates two distinct operational zones: an upper tank for thermal pasteurisation and a lower horizontal tank for batch freezing.

The upper tank pasteurizes the mixture, heating it before a cooling and maturing phase. The mixture is then transferred to the lower tank for rapid freezing. A horizontal freezer chills the mixture while a mixer churns it, preventing large ice crystals and ensuring a smooth consistency. The machine's algorithm controls the mixer's torque, allowing for the creation of gelato and sorbets with varied structures.

Operation begins by filling the upper 15-litre tank with the mixture. Operators can select from various pasteurisation programmes, including heating cycles to 85 °C or 65 °C, followed by pause times and cooling to 4 °C for maturation. The upper tank is equipped with a stainless steel mixer and agitator shaft with polyethylene (PET) scrapers. A defrost switch facilitates mixer restarts. The mixer is directly driven via gearboxes lubricated for life, with an inverter and acceleration ramp protecting the transmission from mechanical stress. The machine features a transparent cover and a double lid for adding ingredients, and a flush-mounted faucet at the tank's base. An external, removable transfer channel connects the tanks.

The lower tank also features a stainless steel mixer and agitator shaft, but with self-adjusting, long-lasting POM scrapers. It operates independently with its own compressor and inverter. The machine boasts an on-board computer with 61 programmes. This includes 1 standard mixing programme, 40 free programmes for recipe adjustment and heat treatment up to 115 °C, and specific pasteurisation programmes. For freezing, there is 1 programme with time control and 5 programmes with temperature control. Additionally, 7 programmes offer density control for the batch freezing process, and 7 circuit programmes allow combinations of up to 5 different programmes. Operators can dynamically change cycles in progress, and new parameters can be saved. The mixer speed is variable, managed by PID temperature control with full integration between the inverter and electronics. Malfunctions are indicated by acoustic and visual signals.

The RHB15/100 has a production capacity of 100 litres per hour. Its physical dimensions are 600 mm in length, 830 mm in width, and 1651 mm in height. The unit operates on a 400 V electrical supply and weighs 440 kg. It is available with various cooling systems, including air, water, mixed, remote, and tropical configurations.

The removable transfer channel and the defrost switch for the mixer are present. The machine is listed in catalogues under bar equipment and ice cream machines.
