Thermal treatment for pasta: cooler mod. RF

PTG offers a wide range of solutions for the fresh product thermal treatment to reduce the bacterial charge, avoiding the proliferation of the microorganisms causing the deterioration of both the nutritional properties and the organoleptic features of the fresh product, such as colour, taste and texture.

The belt cooler is used to decrease rapidly the temperature of fresh filled pasta and pasta sheet previously treated to the value required to guarantee the required shelf-life for the sales distribution. The cooling phase must be realized in a quick way to do not allow the re-activity of the enzymes and the proliferation of bacteria and thermo-sensible microorganisms.

Residence time and treatment temperature are set according to the characteristic of the fresh pasta product like shape, surface/weight ratio, filling quantity, type and composition, PH level, etc… as well as the request in terms of conservation once the pasta is packed. Usually, the last tiers are used to stock the product before the packing process.

Size and overall equipment dimensions are developed according to specific needs in terms of productivity and cooling desired effect.On demand, PTG offers customized solutions with more than one machine for the product conditioning (drier & cooler) placed on a single unit, saving the space in the working area.
