A coating pan is a kitchen tool used primarily in the food industry for coating various types of food items, such as candies, nuts, and pharmaceuticals. It consists of a round, shallow pan that rotates, allowing for even distribution of coatings like chocolate, sugar, or other flavorings. The gentle motion helps achieve a uniform layer without damaging the food. Coating pans are often used in conjunction with other equipment, such as sprayers for applying liquid coatings or drying ovens for setting the coatings. They are essential in the production of products like M&M's and other confections, ensuring a consistent finish and enhancing flavor.
