Sandvik Process Systems Rotoform granulation process

Rotoform is a specialised granulation process which delivers process solutions for the food industry. The granulation process is recognised as one of the best means of delivering pastilles of highly uniform shape, stability and quality, in an environmentally friendly manner. While this Sandvik process continues to be used for the bulk solidification of sulfur in many of the world’s largest oil and gas refineries as well as for agrichemicals and fertilisers, it is becoming increasingly popular within the food industry globally.

Pastilles and micropastilles are all possible using Sandvik Rotoform.

The continuous Sandvik steel and stainless steel belts can be tailored to develop high-performance systems for drying, cooling, freezing, baking and ‘live storage’ accumulation applications. They can also be used for conveying applications such as meat cutting lines and in chocolate production. Inherently hygienic, the flat smooth surface of the Sandvik stainless steel belt is impervious, thereby preventing the absorption of bacteria, odours or flavours. Its hardness and strength not only make it long lasting, but also enable it to be easily cleaned and sterilised.

This Sandvik system is used extensively in processing through cooling with food products ranging from fats and emulsions to chocolate and chewing gum base. The transfer of heat from a melted product to the belt, cooled by water on the underside, enables quick and controlled solidification of the melt.

Alternatively, the receptive Sandvik stainless steel belt can also be used in the fast tunnel freezing of such items as coffee and tea extract, prawns, fish and fish fillets.

To further prove its multipurpose, Sandvik dehydration systems offer fast throughput, low bacteriological count and optimum drying cycle profiles - all with reduced operating costs, for producing high-quality dried fruit and vegetables.
