Cutting-edge steam-vacuum pasteurization technology for nuts and seeds. The technology achieves a 5-log reduction of harmful pathogens, such as salmonella, E.coli, listeria and others while maintaining the natural flavors and qualities of the product.
Pre-heating the product ensures that the pasteurization step is more efficient. Saturated steam is used to achieve a >5 log reduction with no moisture pickup. The partial vacuum enables pasteurization to take place at low temperatures and without oxidation.
The loaded bins move automatically through the sections, reducing the need for operator oversight. With no drying or chemicals required, the unit cost of operation is <EUR 0.07/kg.
After the elimination step, the product can be roasted with perfect control of roasting degree to match flavor profiles. The bins then move automatically to the cooling platform, where the load is cooled with HEPA filtered chilled air until the ambient temperature is reached.
As the product is treated in separate bins, minimal cleaning is required for the platform itself. Maintenance costs are also reduced as there are fewer moving parts and lower wear and tear.
The Bühler NapaRoast StatiSafe pasteurization system features intuitive touch screen control that ensures easy operation and safe, efficient production. Equipped with safety circuits to prevent damage from improper use, the system automatically stops in emergency situations. For enhanced quality control and food safety, it logs real-time and historical data, ensuring full traceability.
The Bühler NapaRoast StatiSafe system can treat whole, sliced or diced product and pieces of all shapes and sizes. Alongside this flexibility, it offers a wide range of capacities, ranging from 200 kg/h to 6,000 kg/h.
