GEA engineers have now developed a special saw-tooth edge for involute blades that guarantees high-quality slicing without the need to first crust freeze products, such as cooked sausage and ham. By saving energy costs from the very first cut, this machine upgrade delivers a direct and sustainable improvement to the process’s energy footprint. Slicing with a saw-tooth edge reduces the cutting force exerted on the product. GEA’s new involute blades with saw-tooth edge reduce wastage and ensure a high proportion of on-weight portions.
