Sevval Manufacturing is a global coffee roasting equipment manufacturer ?to meets the needs of both in-store and commercial.

?The coffee roasting process follows?coffee processing?and precedes?coffee brewing. It consists essentially of sorting, roasting, cooling, and packaging but can also include grinding in larger scale roasting houses. In larger operations, bags of green coffee beans are hand or machine-opened, dumped into a?hopper, and screened to remove debris. The green beans are then weighed and transferred by belt or pneumatic conveyor to storage hoppers. From the storage hoppers, the green beans are conveyed to the roaster. Initially, the process is?endothermic?(absorbing heat), but at around 175?°C (347?°F) it becomes?exothermic?(giving off heat).^[1]?For the roaster, this means that the beans are heating themselves and an adjustment of the roaster's heat source might be required. At the end of the roasting cycle, the roasted beans are dumped from the roasting chamber and cooled with forced air.
