Compressed Air Best Practices - March 2008 - (Page 11) Focus Industry FOOD PROCESSING | 03/08 | The facility manufactures fresh and dry yeast for bakeries. Yeast is grown using an aerobic fermentation process. Starter yeast is grown from test tube quantities through a series of five fermentations that progressively increase in size. Fermentation consists of combining a starter portion of yeast with the controlled addition of nutrients, including sugar and oxygen. Oxygen is supplied by compressing air and bubbling it through the fermentation mix. Even though the fermentation is done at atmospheric pressure, the air pressure must be approximately 11 psig in order for it to flow from the bottom of the fermenter. A small amount of air is used to start and as more yeast grows the airflow is increased. The facility has multiple commercial size fermenters that are typically at different stages of the process. Mr. Ed Ball of Process Air Solutions (www.processairsolutions.com) identified this fermentation process as a good candidate to realize energy savings through the use of a HSI variable frequency drive blower and control system, and a subsequent evaluation was initiated. CO2 O Replacing inlet throttle-valve blower controls with VFD’s saved 2,502,000 kWh per year.
