This cooling paddle is a great way to rapidly cool soups and other foods that can't go into a blast chiller and is specifically designed to fit perfectly in hotel style pans. Its smooth exterior makes it easy to remove foods to reduce waste, while also ensuring the paddle is easy to clean and sanitize. For best results, do not use in temperatures greater than 195 degrees Fahrenheit or less than -20 degrees Fahrenheit. To preserve the life of your paddle, fill with ice and water and use immediately. It is recommended to fill the units entirely with ice, then add cold water at or below the max fill line to fill in the voids around the ice cubes. If you want to freeze your paddle ahead of time, fill the paddle with water at or below the max fill line, and NEVER exceed the line. Place the paddle in the freezer on its side to allow for optimal space for the water to expand. Once frozen using either method, the product can be used to bring the food temperature through the temperature danger zone (41 degrees F - 135 degrees F).
