Coffee production is a great example of an application of a double dump valve, which offers long-lasting dry material handling with minimal wear and air seepage. Once the coffee bean has been harvested, it must be dried and husked. For the wet method, manufacturers use pulping machines to extract the majority of the husk of the bean. Following the fermentation process, hulling machines remove the remainder of the husk and polish the bean. If the coffee bean or husk becomes airborne during the pulping or hulling process, the dust collection system captures the material and discharges it using the double dump valve. This type of valve has tandem gates that work together to collect and dispense coffee bean fragments without compromising the positive or negative pressure in the system. A double dump valve is engineered to handle a variety of dense, abrasive particles without wearing out or becoming jammed like a knife gate or rotary valve. Because of its cost-effective, low-maintenance design, it can save your facility valuable resources over its operational life.
