Established in 1978, STALAM is the world leader in the development, design and manufacture of equipment where capacitive electromagnetic fields at I.S.M. metric frequencies (RF fields) are exploited for a variety of thermal processing and drying applications on raw materials, intermediate and finished industrial products. Company Profile As a member of AEI (Italian Electronic and Electro-technical Association) STALAM cooperates actively with prestigious universities and research institutes for the development of the RF technology both as to generation techniques and to technological applications....

Radio Frequency dielectric heating is a drying and thermal processing technology based on the dissipation of electromagnetic energy within the product. Unlike conventional techniques, where heat is transferred to the product through its surface from an external heat source by conduction, convection or irradiation, a Radio Frequency field generates heat directly inside the entire product mass - that is why the related mechanism is called “endogenous” or “volumetric”. The heat generation is instantaneous and allows a rapid, uniform and perfectly controlled process. Water molecules are highly polar,...

Over the past decades STALAM has successfully introduced the Radio Frequency technology to many industrial drying and thermal processes and is the first company in the world having developed continuous RF disinfestation, sanitisation, pasteurisation and sterilisation equipment for solid products - either packaged or in bulk - and for liquids in the tube. The use of RF heating to sanitise food products combines the technical and economic advantages that brought to success this technology in other industrial applications. Food Safety The market demand for natural yet microbiologically safe products...

Perform an organic process, retain the natural properties Disinfestation and sanitisation of agricultural commodities STALAM developed and patented SANICROP+, an innovative chemical-free solution for the organic disinfestation and sanitisation of dry agricultural commodities, based on the Radio Frequency technology. Thanks to the mild heat treatment performed by the RF electromagnetic field, all physical, chemical, nutritional and sensorial characteristics of the substrate are preserved at their best. How it works? In the SANICROP+ sanitisation system, the product is fed by means of an in-built...

Fast and effective treatment The physical, chemical, sensorial and nutritional properties are preserved at best thanks to the mild heat treatment, so that a healthy and safe product can be obtained without using fumigants, anoxic atmosphere or other chemical treatments. Energy efficient and environmentally friendly technology Approx. 25 kWh are required to disinfest about 1 ton of product (about the double for a thorough sanitisation process), which translates into a cost of 2÷4 EUR/ton, competitive with the conventional technologies. No effect on the germination of seeds Up to 10x faster than...

Food and Pharma industries are nowadays dealing with the increasing attention of consumers to natural taste, flavour and functional properties preservation, together with ever stricter food safety and hygiene regulations imposed by local and international authorities. With the purpose of serving the needs of these industries, STALAM has developed the SANILEAF+ series equipment for the batch sanitisation of spices, aromatic herbs and medicinal plants. Environmentally friendly process fully compatible with organic farming produce due to no need of ionizing radiations, fumigants, chemicals nor modified...

Pasteurisation of products in bulk Pasteurise gently, retain flavour and natural properties With the SANIBULK+ and SANIPACK+ series equipment, food products compatible with the RF technology can be pasteurised in minutes in bulk or directly inside their commercial packaging. High reduction of the microbial load (molds, yeasts and pathogens) can be achieved in a very short time, thanks to the fast and uniform heating process throughout the product and its packaging (if any) which does not rely on (slow) heat transmission, typical of conventional methods: the required microbial kill level is attained...

Pasteurisation of liquid products in the tube Fast treatment, utmost freshness SANIFLUID+ has been specifically designed for the continuous pasteurisation and sterilisation in the tube of liquids and other fluidised (i.e. pumpable) products, even with suspended solids. The fluid substrate is continuously pumped through one or more tubes made of a food-grade, RFtransparent material, having a suitable diameter according to the specific product. The tubes are placed between especially designed electrodes, powered with relatively low RF voltages, that amplify and concentrate the electric field on...

Minimal thermal treatment, better quality, safer product Floor space saving modular system The rapid and uniform temperature increase within the product, also in the suspended solids of any size, eliminates the risk of underor over-processing. The microbial inactivation is performed at lower temperatures and in a shorter time compared to conventional thermal processes. Moreover, a better preservation of the physical, chemical and sensorial characteristics of the product is achieved, with reduced use of additives such as colours, flavours, thickeners, etc. normally used to compensate for product...

Moreover, frequent washing of the pasteurisation plant is not necessary thanks to the low temperature treatment and no contact with any heating element: this allows savings of up to 15-20% in costs (around 1,5-2 eurocent /kg). EGGPURE+ can be easily installed in any existing production plant. In collaboration with Innovo Solutions, STALAM has developed EGGPURE+, a specific Radio Frequency equipment for the pasteurisation of liquid egg at low temperatures, which ensures both the required microbial inactivation and the preservation of the sensorial properties of the product. The treatment can be...
