The Natec Network FreeTherm is a purpose designed batch processing system for a complete range of product types, viscosities and compositions, such as: Processed cheese, pasta filata types, sauces, purees, baby food, meat, pet food and more. All ingredients are gently mixed by two independently controlled augers. Product heating utilises unique direct steam injectors and the product is de-aerated using an integrated vacuum system. Temperature is accurately monitored by unique self-cleaning temperature probes. After processing, the product is discharged into an R&D trolley or an insulated buffer tank, with an agitator, to wait for delivery to downstream systems. Great flexibility and different options make the FreeTherm a multifunctional batch processing system for a wide range of products.
