HOFFMAN STATIONARY VACUUM CLEANING SYSTEM

qfcrsipfcmt cleunliness..jf±cjuvBis valuable produiitl The Holly Sugar Corporation has always been proud of—and noted for— its "housekeeping". In its refinery at Brawley, California, three or four men were assigned to daily hand-sweeping but the management soon realized that sweeping removed only part of the dust while the remainder was moved and rescattered through the plant. Hoffman was asked to survey the requirements; and designed a stationary vacuum cleaning system, with the following features: 1 . Adequate capacity for rapid and thorough cleaning of the entire plant with sufficient inlet valves to make the work as easy as possible. 2. Convenient location of the separators so the collected material is dumped directiy into "remeit" for recovery of sugar. 3. Connections for 2" vacuum hoses at points where spills had previously

required laborious and costly handling. 4. Much of the dust in the plant was seeping from the housings of the bucket elevators and storage bins, so special vacuum connections, creating a slight negative pressure from the enclosures into the pneumatic system, prevented the material from escaping as dust. This was then recovered with the rest of the sugar picked up in vacuum cleaning. As a result of the Hoffman installation, Holly Sugar now has a cleaner plant—with only two sweepers! Let Hoffman offer recommendations for your needs, whether -they are cleaning, conveying, recovery or all three. Your letter for detailed information or an engineer's survey will get prompt attention,, without cost or obligation.
