Sterilization Technology

For thermal processing of low-acid foods packaged in hermetically sealed containers dft technology offers equipment for nearly all capacities. dft is focused to STOCK batch type retorts made of stainless steel which can be used for all kind of products and packaging materials. Rotation or rocking during the process may improve the product quality significantly. The rotors are made from stainless steel as a standard. Tailor-made design, best use of energy and simple operation takes centre stage. For loading and unloading of retort cages equipment is offered for all kinds of containers. The dft program is completed by a fully automatic Sterilization System with SCADA, which is controlled by one person only.
