The Spirajoule® technology is an exclusive process for thermal treatment. It is designed with a worm scre conveyor electrically heated by a low voltage current. The screw heat the product due to the joule effect.The product temperature is precisely controled due to the regulation of the screw temperature setting. The dwell time is regulated by the setting of the screw rotation speed.The technology is a simple and economical process with accurate and efficient operation for the heat treatment of up to 700°C of wet or dried products.
The SPIRAJOULE® process series is best for thermal treatments like sterilization (while preserving microbiological and organoleptic properties), roasting (of meat for example), toasting (of seeds for example), drying, defrosting, and conveying (maintaining temperature). It can treat all kinds of products used in the chemical industry, food ingredients (for example: spices, herbs, cereals, dehydrated fruits or vegetables, seafood...), environmental sector such as scrap or waste treatment (muds, sawdust, shavings...), and etc.
