COMMERCIAL GRAIN DRYERS ZIMMERMAN TOWER DRYERS

PROMISING QUALITY Walter Zimmerman of Litchfield, IL, first conceived of Zimmerman Grain Dryers in 1963. He was designing grain dryers that needed to be built using components that were high quality and long lasting. To meet this need, he established a long-lasting relationship with the leading manufacturers of commercial blowers and burners, which are still in place today. URPASSED GINEERING Using his keen foresight that made him an industry leader, Zimmerman developed concepts such as vacuum cooling, stainless steel sidewall sheets, and dryers built for efficiency, cleanliness, and high...

GRAIN PROTECTION - STARTING RIGHT FROM THE TOP The Zimmerman Tower Dryer is designed to provide the optimum balance of time, airflow, and temperature to maintain premium grain quality. Grain enters the dryer at the top and falls into a self-cleaning grain receiving chamber. The chamber creates a grain cushion, and with grain falling on grain, helps reduce plenum roof wear. This chamber also provides a means of distributing grain evenly around the dryer. At the top of the dryer, the garner bin has a full 40 inches of wet grain storage and the area is completely sealed to help retain grain...

ZIMMERMAN TOWER DRYERS CONSISTENT, EVEN DRYING Midway down the heat section of the dryer are Zimmerman’s patented (US6035544) grain inverters. By inverting all but the outside two inches of grain from the outside of the grain column to the inside, inverters promote more uniformly dried grain, even and consistent drying, higher test weights, maximum grain quality and reduced fuel usage. The inverters redirect the warmest grain from the inside of the column to the wettest grain at the outside of the column. The wet grain remaining at the outer 2 inch of the column is dried using the captured...

TOUCH SCREEN CONTROLS EASY TO OPERATE, EASY TO MAINTAIN Operation of the dryer is performed with a state-of-the-art Allen-Bradley CompactLogix™ Programmable Logic Controller (PLC). This provides not only a complete safety monitoring and trouble-shooting menu but performs system verification and operator prompts during start-up and operation. Zimmerman PLC controls reduce timers, switches, and mechanics while providing built-in expandability and flexibility designed to meet changing operational and drying needs. A large, high quality Allen-Bradley PanelView™ Plus 1000 touch screen controls...

WATCHDOG™ ENGINEERING SUCCESS Need more hands-on control over your drying? The optional WatchDog Remote Dryer Monitor is the perfect complement to the already innovative Zimmerman PLC control system that is defining the next generation in dryer controls. WatchDog, a web-based application, works with the Zimmerman PLC dryer control system to allow remote monitoring of various dryer functions, such as moisture, temperature and dryer status, all from the convenience of any web-enabled device. Except for the start-up menu, WatchDog lets you control anything remotely that can be controlled via...

ZIMMERMAN TOWER DRYERS Self cleaning cushion box on plenum roof reduces grain damage and plenum roof wear. SEE PAGE 4 FOR MORE INFO. The 12-3/4 inch grain columns surrounding the heat plenum chamber allow the grain to receive all BTU's from the burner, improving efficiency. Inside and outside safety ladders, cages and catwalks provide safe and easy access to all areas of the dryer. SEE PAGE 12 FOR MORE INFO. Patented (US6035544) Grain Inverters equalize moisture content and temperature of the grain column, improving quality and efficiency. SEE PAGE 5 FOR MORE INFO. In-line Maxon NP-LE-AL...

Gravity inlet does not require leveling auger, reducing the number of moving parts. Stainless steel outside sheets greatly extend dryer life. The screens utilize different size perforations to reduce particulate emissions. SEE PAGE 11 FOR MORE INFO. Uniform low velocity heated air improves efficiency and quality as well as reducing particulate emissions. SEE PAGE 11 FOR MORE INFO. Heavy-duty overall construction results in an extra rigid structure on minimal of ground space. Reducer cone equalizes air velocity past burners for optimum combustion and provides step-in access to burner...

MIXED-FLOW BLOWERS HIGH-VOLUME AIRFLOW, EFFICIENT HEAT DISTRIBUTION All Zimmerman dryers are optimized to provide just the right amount of airflow. Too little airflow adversely affects capacity, too much airflow adversely affects the efficiency. Depending on the dryer size, one, three, or four industrial-duty mixed-flow blowers are used. Internally mounted, these in-line mixed flow blowers operate at slow speeds, which means low noise levels, low electrical usage and results in long blower and motor life. Unlike centrifugal fan designs on other dryers, airflow from the Zimmerman blowers is...

ZIMMERMAN TOWER DRYERS MAXIMUM PARTICULATE RETENTION Zimmerman tower dryers are designed to retain bees’ wings and particulate matter within the drying columns. The largest standard hole size on the exterior screening of the dryer is 0.078 inch diameter perforation. After the grain is turned, the perforation size drops to a diameter of 0.0625 inches. Solid non-perforated exterior sheets are used at the grain inverters and at the top and bottom of the grain columns to help ensure that particulates are not expelled from the dryer. As grain exits the heat section of the dryer it enters the...

CATWALKS, LADDERS AND CAGES Strong structural design and heavy duty materials go into the manufacturing of catwalks, ladders and cages. Patent pending fan style catwalk conforms to fit the shape of the dryer. SWING GATES Swing gates are installed on every platform access point for added safety. EASY ACCESS All areas of the dryer can be accessed through up to four entry points making cleanout, inspection and maintenance easy.
