Manufacturer Spices it Up

Seasonings and spices are used to enhance the flavor of food. Chefs have been using a blend of seasonings for centuries. In fact, the characteristic taste of any region’s cuisine began with its very own signature blend of spices. Whether in fresh, whole dried, or pre-ground dried form, all seasonings must be fresh in order to be effective. Their freshness is reliant on proper packaging; poor packaging can result in stale seasonings.

A manufacturer of custom blending and packaging of end-use dry food ingredients added seasonings and spices to their expanding product line. This growth and increase in production caused their existing dry dust collection system to overload. Coupled with frequent equipment wash downs, the dry filter media began to clog. The high pressure across the filter resulted in reduced airflow velocity, allowing dust to settle in the ducts.

The customer turned to AAF® for a solution that would allow them to keep up with the increased production without clogging and overloading the filter media. AAF® recommended the stainless steel Food Quality RotoClone® W due to its ability to handle sticky dusts, while ensuring performance is maintained without interruption or downtime. Unlike barrier filters, such as pulse-jet filters which have to form a dust layer or cake to build resistance, the RotoClone® W requires no dust build up for immediate efficiency.


A central coal-fired electric utility company contacted AAFin need of a solution to a number of challenges they werefacing related to the conversion to Powder River Basin(PBR) coal. The baghouses that were currently being usedwere encountering many operational problems, mainlydue to the new type of coal and its specific characteristics.The customer was concerned about meeting NFPAregulations, eliminating fire hazards, and also maintainingits current status as a reliable and cost effective producerof electricity for their customers.


AAF® conducted a room-by-room refit with a single all-stainless steel Food Quality RotoClone® W. Designed to operate automatically and require minimal maintenance, this unit met all of the requirements presented by the customer. The bearing pedestal eliminated flat surfaces that attract material buildup, making it easier to clean. Additionally, the RotoClone® W was capable of being plugged into the existing plant systems with a minimum amount
of disruption.


The RotoClone® W is able to handle the high dust loadings that result from the handling of their dry food ingredients. Its access doors allow easy access to clean and inspect the unit. The maintenance manager reported that unlike their old unit, the RotoClone® W continuously maintains constant exhaust volume and requires almost no maintenance.
