Automated continuous heat treatment
A range of innovative fully engineered continuous heat treatment equipment is now available for heat treating bulk solids under controlled atmospheres. The technology ensures optimum retention of active ingredients by minimising the amount of steam and lowering the temperature required to pasteurise or to sterilise the product. The process is entirely automated and can treat products from powders to particles several centimetres in diameter. Applications include decontamination insect removal, roasting, toasting, drying and pre-cooking. Several machine parameters such as temperature profile, residence time and atmosphere can be customised so that a large range of products can be processed without damaging their organoleptic properties. In addition, the system is particularly suited for fragile and sensitive products. Products such as gums and spray-dried powders previously considered as impossible to treat are now being successfully treated in Revtech industrial units with up to 8 log reduction in pathogenic organisms.
