Developed to meet the specific needs of the food industry, our hardeners <\/strong>provide an innovative solution for the surface freezing<\/strong> of delicate or complex products. Used as an alternative to traditional spiral freezers, they offer a fast and efficient process through a refrigerated plate<\/strong> that freezes only the lower layer of the product, preventing deformation and residue build-up.<\/p>\n<\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div>![](\"https:\/\/www.bifreezer.com\/wp-content\/uploads\/2025\/09\/BiFreezer-Hardener.png\" "\\"BiFreezer-Hardener\\"")

<\/div><\/div>How a hardener works<\/h2><\/div>The hardener is a tunnel in which the food product passes for a few seconds over a refrigerated plate<\/strong>, without the use of ventilation or thermal insulation.
