Did you know that harmful bacteria grows most rapidly in foods at temperatures between 41F (5C) and 135F (57C)? That means food at room temperature could be most at risk for creating food-borne illness for you and your customers. The Rapi-Kool Cold Paddles eliminate this hazard, however, with their unique and patented design to chill foods from the inside-out. The Cold Paddle works by filling it with water and letting it freeze. When soups, stews and other hot liquids need to cool, place the Cold Paddle into the food, and in a short-amount of time the food will be safe to store. For the best results, keep plenty of Cold Paddles on hand for different dishes and freeze them ahead of time so you will always be prepared. The Paddles are made of durable, dishwasher and food-safe plastic that is easy to sanitize and clean. Use over and over again for the safest chilling method on the market. - Plastic; blue - NSF listed - Capacity 64 oz - Diameter 4-3/4 in - Height 13-1/2 in - Sold per each ***CALIFORNIA PROP 65 WARNING: This product contains a chemical known to the State of California to cause cancer, birth defects or other reproductive harm.***
