SAFETY STRATEGIES protection. Their purchases, though, may not have afforded truly sanitary solutions. In reality, there's a big difference between "stainless steel" and "sanitary," when it comes to conveyors. Stainless steel is certainly the right material to use in applications that call for regular washings with light chemical cleaning agents. While a basic stainlesssteel model can be washed throughout the day as needed (depending on how it's built), that doesn't necessarily mean the equipment is sanitized or cleaned. Sanitizing or cleaning a conveyor involves an entirely different process than simply washing it down. Much of that process depends on the way the system was initially designed. Select the Correct Sanitary Conveyor According to John Kuhnz of Dorner Mfg Corp., Hartland, WI, well-built sanitary conveyors incorporate a variety of distinct hygienic design features and capabilities. To help ensure that an organization's expectations are met, he reminds those researching various sanitary conveyor systems to consider these key points: ■ Where will the conveyor be located and for what type of application will it be used, i.e., raw food/ingredients or sealed or packaged food items? ■ How accessible will the conveyor be for purposes of taking it apart? ■ Will disassembling the conveyor be easy, i.e., accomplished by one person with no tools? ■ Would the conveyor's design allow effective, required washing and sanitizing? What makes a truly sanitary conveyor? The goal of sanitary conveyors is to, as much as possible, eliminate any chance of contamination. By their very nature, conveyor systems are an excellent source of contamination-particularly on the processing side where raw food and ingredients are moved. A sanitary conveyor works to eradicate the areas where contamination can develop, starting with the frame design. A truly sanitary conveyor gives personnel complete and easy access to all areas of the system for cleaning. With the ability to reach every part of the conveyor with water, soap, or other cleaning agents, there's no chance of product collecting and growing bacteria. Such conveyors also remove harbor points, blind spots, and level surfaces within the frame structure, and replace them with rounded cross members to prevent food and water from accumulating. This design element is important because it doesn't take long for components within a conveyor, such as the motor, to begin heating up collected food particles and speeding contamination. In addition, the overall frame openness means that any product that falls off the belt will land either in a catch pan below or on the floor; nothing gets trapped within the frame. Another common hygienic feature of SEPTEMBER 2016 Reduce Maintenance Cost by up to 40% Keeping oil clean - It's your best insurance! 1 Clean incoming oil - because new is NOT clean oil 2 Keep oil clean - remove solids AND moisture Keep your first fill from starting things off on a dirty foot.
