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...

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...

Applications for industrial bakeries The oven is the “heart” of any bakery. The baking oven is where the product gets its shape, texture, colour and taste. You could say it is where a basic mixture of ingredients becomes “a product”. Yet, ovens can be used not only to bake, but also to carry out other processes, all related to the supply of a certain quantity of thermal energy to the product. Sometimes, heating by electromagnetic waves may even deliver results that cannot be achieved under any circumstances with a traditional oven. Based on the above considerations, over the years STALAM...

Reduce Acrylamide, enhance flavour and crispness Post-baking drying Radio Frequency post baking drying allows to eliminate the excess moisture from the product rapidly and efficiently, without causing over-baking (excessive browning) of the surface, with added benefits to productivity and quality. This special patented electrode is designed to apply a highly-concentrated electric field to thin or very thin products (such as biscuits, cookies, cereals etc..) even when fed with low RF voltages. How it works? Removing the final excess moisture from a baked product is a challenging task: the...

Moisture reduction and leveling RF drying allows to achieve an accurate moisture level inside the product and to reduce cross-band moisture differential at the exit of the baking oven. The process control is instantaneous. Final RF drying increases conventional oven throughput and reduces bakery floor space requirements and energy consumption. Enhanced flavour and crispness The RF treatment improves flavour retention, colour control, crispness and shelf-life. It also reduces checking problems. Final drying by RF allows to reduce surface browning and Acrylamide formation. Reduced Acrylamide...

WAVEBAKE+ Baking of white-crust bread Baking fast with no crust STALAM has developed WAVEBAKE+, a revolutionary oven based on the RF technology that ensures a perfectly even and controlled baking process with virtually no crust formation. How it works? The possibility of using electromagnetic waves for a full baking process without conventional heat depends on the ability of the equipment to deliver and spread uniformly the energy onto the dough pieces. STALAM has designed a special “variable configuration” electrode (patented), which is capable of delivering controlled quantities of RF...

Pasteurise in minutes, achieve long shelf-life STALAM is the first company in the world having developed industrial pasteurisation equipment by Radio Frequency for packaged products such as bread loaves, fresh pasta, gnocchi, etc. 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 which does not rely on (slow) heat transmission, typical of conventional methods: the required microbial kill level is attained in a few minutes rather than one hour or...

Test & Demo facilities The STALAM testing lab is an integral part of our R&D and engineering departments. Through testing and analysis of the results, our experts can study in details the characteristics and behaviour of a product submitted to the Radio Frequency field, thus assessing the technical and economic feasibility of drying and thermal processes on specific substrates, based on customers’ requirements. In the same way, our engineers can identify the best process parameters and the technical specifications of the most suitable RF equipment to perform such processes. STALAM’s R&D lab...
