The 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 Natec Network direct steam injectors and the product is de-aerated using an integrated vacuum system. Temperature is accurately
monitored by Natec Network unique self-cleaning temperature probes. After processing, the product is discharged into 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.

The Magnet for Emulsion technology (M4E) combines turbulent flow conditions with the LORENTZ force induced by a permanent magnetic field. In a turbulent flow, particles (powder particles or oil droplets) spin around and collide. This results in particle deformation and break-up. The LORENTZ force will further intensify this spinning and colliding effect. As such, the combination between the turbulent flow conditions and the LORENTZ force create the perfect environment to make stable emulsions and lump-free powder dispersions. The M4E technology is mainly an “one-pass” technology, meaning once the product has passed the magnet, it is perfectly dispersed and / or emulsified.

The RotaTherm® is the world’s leading Direct Steam Injection Continuous Cooking System. Versatile processing set up for optimisation. The RotaTherm® allows the heating and processing parameters to be set as each product/ recipe requires. These include cooking temperature, direct steam injection heating profile, shear, pressure, mixing as well as various other settings – all with a precise level of control. Learn more about how it works.

Long runs
The RotaTherm® continuous cooking system can be operated continuously for up to 156 hours at a time. Learn about its many other benefits.

Applications
The RotaTherm® is used around the globe to cook and process a wide range of food products such as pet food, pie fillers, taco meat, all processed cheese varieties (including high/low moisture), baby food, chunky sauces, purees, dips, desserts and more.

The RotaTherm® direct steam injection continuous cooker is suitable to process most product that is ‘pumpable’ through closed pipework cooks in a single pass (- all ingredients are combined to create a single blend before cooking) and has water in the formulation (or can accept moisture addition in the cooking phase).

Innovative spirit continues
The RotaTherm® continuous cooker was invented in the 1980s by Robert ‘Bob’ Smith. Over the last four decades we have continued to innovate and develop its performance. Today, over 200+ RotaTherm® continuous cookers are installed around the globe optimally and continuously processing tonnes of product hourly-daily-weekly!

We deliver all the flexibility and accurate control you need to produce a wide and outstanding range of meat products with specific requirements in regard to appearance texture as well as superior bacterial safety. Natec Network solutions enable efficient and hygienic processing for pasteurising, sterilisation or aseptic applications with fast processing techniques like meat rendering and low temperature defatting (MDM / FDM).

The ShearTherm is specifically developed to include basic process requirements and extensive shear and emulsification options, in a modular design that can be individually adapted to the customers’ needs. Many processes are combined and controlled in the small ShearTherm footprint, delivering maximum process, recipe and application flexibility. With full control of all process functions it delivers excellent finished product characteristics and quality – even with particles!
The ShearTherm is the perfect choice for high powder concentrated and plant-based products. In combination with our innovative and unique Magnet for Emulsion (M4E) technology, together with a special multi directional pre-mixer and agitator, it delivers short and efficient mixing of all ingredients. The integrated vacuum system and different homogenization units, each with controlled variable speed, guarantees a very high repeatability, short batch cycles, 100 % homogeneous and lump free product. Product heating utilises unique Natec Network direct steam injection while temperature is accurately monitored by Natec Network self-cleaning temperature probes.
