Coffee conveyed from bulk bags to roaster to packaging

Mayorga Coffee produces 30 different coffee roasts, and supports local organic farming methods by working directly with small, family-owned coffee growers in Mexico, Bolivia, Colombia, Costa Rica, El Salvador, Guatemala, Honduras, Nicaragua and Peru.

“We produce a product that is sustainable, not only for the planet, but for the people growing it as well,” said Erin Dall, president and COO. Mayorga sees its direct purchases, without complex supply chains, as an important factor to reducing poverty in Latin America.

Founded in 1997 and headquartered in Rockville, Maryland, the company until recently operated a second 3,900m2 (42,000 sq ft) roasting and packaging facility in Miami, Florida to produce its premier product, Café Cubano Roast organic coffee, in vacuum-sealed brick packs. 

To transfer the coffee beans from roaster to grinder to packaging line, the company installed a bulk handling system comprised of two bulk bag dischargers, three flexible screw conveyors and a bulk bag filler, all from Flexicon Corporation.

Roasted coffee beans are discharged from the roaster into open-top bulk bags and delivered to a BFF BULK-OUT bulk bag discharger. A forklift then positions a bag-lifting frame immediately above the bag, allowing an operator to slide the bag’s four lifting straps into Z- CLIP strap holders, and the forklift to lift the frame – with suspended bag – into receiving cups atop the discharger’s frame posts.

The discharger houses a bulk bag spout interface chute with an integral access door. With the bulk bag in position, the operator opens this door to gain access to the bulk bag spout tie. Once the spout has been untied, the access door is closed while roasted beans are discharged from the bulk bag.
