Ice cream machine STAFF Ice system 1959 PT151

The STAFF Ice system electric pasteuriser, article PT151, is designed for professional food preparation.

A pasteuriser heats liquids to a specific temperature for a set duration to reduce microbial load, then cools them to a preservation temperature. This process is crucial for food safety and extending shelf life while maintaining product quality.

The PT151 features a stainless steel mixer and an agitator shaft equipped with a top seal. It includes polyethylene (PET) scrapers and a tank defrost switch. A non-slip mat for the tank base is also supplied. The mixer's transmission is protected by an inverter with an acceleration ramp.

Operation is facilitated by a transparent cover, allowing visual monitoring of the mixture. A double lid is incorporated for the convenient addition of ingredients. The unit's on-board computer offers extensive control, with 57 pre-set programmes. These include one mixing programme for tasks such as mixing, foaming, and washing. Additionally, there are 40 free programmes that allow users to define custom recipes and heat treatments up to 115 °C.

Pasteurisation cycles are available for common mixtures, including heating to 85 °C or 65 °C, with specified pause times and subsequent cooling to 4 °C. An acoustic signal alerts the operator upon cycle completion. A maturing/preservation phase maintains the mixture at 4 °C. The mixer can be set to operate in either continuous or variable mode.

Further programmes include a batch freezing/chilling cycle with time control, a specific pasteurisation programme at 90/95 °C for chocolate-based mixes, and another at 85 °C for general mixtures. A programme at 65 °C with a 30-minute pause is dedicated to fruit gelato syrups. Five cooling/preserving programmes offer temperature control, and seven circuit programmes enable the combination of up to five different programmes in sequence.

Operators can dynamically adjust ongoing cycles by modifying mixer speed or desired product consistency, and save these new parameters. Each free programme can be set to run automatically with its preset parameters. The unit features a multilingual 2.5-inch display that provides visual, alphanumeric, or graphic signals. Acoustic and visual indicators are present to signal malfunctions. The pasteuriser operates on a 230 V supply and has a volume of 15 L. Its dimensions are 600 mm in length, 840 mm in width, and 456 mm in height, with a weight of 110 kg.

The catalogue places this equipment within the bar equipment and ice cream machines categories.
