Valtek Past 180 Batch pasteuriser

The Valtek Past 180 Batch Pasteuriser is a commercial batch-processing machine designed for the controlled heating, pasteurisation, holding, and cooling of liquid food mixtures, particularly ice cream and gelato mixes. It is intended for professional production environments where accurate temperature control, consistent processing, and hygienic operation are required.

During operation, the prepared mixture is loaded into the pasteurisation vessel, where it is continuously agitated while being heated to the required pasteurisation temperature. The agitation system promotes even heat distribution throughout the product, reducing temperature variations and helping prevent the mixture from sticking or burning against heated surfaces.

Once the programmed pasteurisation temperature has been reached, the product can be held at the required temperature for the specified period before entering the cooling phase. The refrigeration system then rapidly removes heat from the mixture, bringing it down to a suitable storage or ageing temperature. Controlled cooling is an important part of the process for maintaining product quality and supporting safe production practices.

The Past 180 incorporates several key technical systems, including the pasteurisation vessel, heating system, refrigeration circuit, agitator and drive assembly, temperature sensors, product discharge system, and electronic operator controls. These components work together to provide controlled and repeatable processing from batch to batch.

The Valtek Past 180 is suited to larger-scale ice cream and gelato production where dependable processing capacity and consistent product preparation are required. Routine cleaning and inspection of the vessel, agitator, seals, temperature-control components, refrigeration system, and product outlet are important for maintaining hygienic conditions, reliable temperature control, and overall machine performance.
