Spent Grain Conveyor

Indpro’s wet spent grain conveyors – iExpel are simple yet efficient systems that help you get rid of your wet spent grain that is left over after the brewing process. These systems meet today’s demands for operational safety, low air consumption, easy cleaning and maintenance. Indpro, based on decades of experience, has configured standardized models to choose from. Our offerings can cater to most of brew lengths of modern commercial breweries. Our spent grain conveyor can also be used in various other industries, where a mass with high moisture content (wet cake) is to be transferred, industries such as food processing, for applications like, various sauces manufacturing, shrimp processing etc.

Spent grain conveyor - iExpel is placed under the lauter tun/mash filter in the brew house. The mass enters the trough through the storage bin/chute which is compressed by variable flight screw conveyor. The de-watering arrangement is provided below the screw to drain the wastewater. The conveying screw pushes the mass through the non-return valve to the conveyor outlet. This region is pressurized by the compressed air/steam connection. The spent grains are conveyed pneumatically in a plug-conveying operation. Thus, spent grains, a by-product of the brewing process, are conveyed to a wet spent grains distribution plant (silo). Indpro’s spent grain conveyor - iExpel offers a simple, quiet and efficient way to convey wastewater spent grain, from the lauter tun to the spent grain silo.
