Fluidized Bed Ovens, Drum Roasters and Toasting Systems

GEMMER Custom-Fit® Fluidized Bed Roasting and Toasting Systems stand for applications of market-oriented, industrial-scale products of the food and feed sector. Many flavors can be achieved with the controllable refining profiles of our process technology systems.

Apart from that, a wide range of roasting degree intensities can be achieved thanks to the individual process control of our toasting and roasting systems. Appearance, product texture and particular flavor properties can thus be created according to the product characteristics to be achieved.

Fluidized Bed Ovens, Drum Roasters and Toasting Systems

The shelf life of breakfast cereals and many other raw products of the food industry can be maximized by roasting and toasting processes. Both the reduced number of germs and the high oxidation resistance are decisive advantages and characterize the quality and shelf life of the processed products.

Apart from that, the typical flavor and the specific product color survive the roasting process. The flavoring properties and specific requirements on quality involve individual process concepts. GEMMER fluidized toasting and roasting systems offer specific and individual application possibilities and allow for almost unlimited flexibility in the production of the most different products.
