Profile STAL-AM 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. As a member of AEI (Italian Electronic and Electrotechnical 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...

RF Technology 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 istransferred 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...

Defrost in minutes, improve quality and yield Tempering and Defrosting STALAM has developed COLDWAVE+, a rapid in-line defrosting equipment based on the Radio Frequency technology that allows a significant reduction of drip losses and minimises product deterioration due to bacterial growth. This fast, uniform and controlled method offers great flexibility in production scheduling and is the ideal solution for many tempering, softening and defrosting processes. How it works? The product is placed on the machine's conveyor belt and is transferred continuously through the RF unit (tunnel)...

Defrosting in minutes Defrosting is achieved in minutes rather than hours or days, even for large product blocks and, if necessary, directly inside packaging used for storage or retail distribution (carton boxes, polyethylene liner/bags, plastic crates, etc.). The process speed and uniformity minimise the risk of product degradation (deterioration of sensorial, chemical and physical characteristics, bacteria growth, etc.), thus helping to preserve at its best the product quality. Higher product yield Tempering to -30/-1° can be achieved with no drip loss, that means eliminating completely...

COLDWAVE+ ensures the rapid and uniform tempering of large meat blocks or individual pieces (cuts), improving the product yield by minimising the drip loss. The product can be obtained at the correct temperature needed for the next process: grinding, cutting, slicing, portioning, forming, dicing, mincing, flaking, tumbling, marinating, deboning, etc. RF defrosting is highly efficient on all kinds of meat, regardless of its shape, size and fat content. mm Individual pieces (cuts) and blocks Thin and thick products “Naked" and packaged products (carton boxes, polyethylene liner/bags, plastic...

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...
