Nut roasting process with halved energy consumption
Achieve significant energy savings while maintaining high-quality roasting for nuts, thanks to an innovative roasting module that seamlessly integrates post-pasteurization to perfect texture and flavor.
Halves Energy Consumption and Optimizes Nut Roasting
The Roast Finish® module from Napasol AG revolutionizes nut processing with its energy-efficient design. Integrated within an automated production line, it follows the pasteurization phase, roasting nuts immediately to minimize energy usage—cutting it by 50%. Capable of processing bulk loads in 2,000-pound bins, it reaches roasting temperatures between 130°C and 180°C, ideal for producing roasted and seasoned nuts, nut meals, and savory snacks. The module supports versatile applications across food, confectionery, and industrial processing industries, handling products from solid whole nuts to granules. With PLC control, it adapts roasting profiles to achieve precise flavors and textures with minimal mechanical damage and downtime. The equipment is designed for easy integration and cleaning, offering engineering support for customization to enhance your production capabilities.
