There is a huge vatiation in candy available on the market, each brand with its own taste, texture and appearance. These features are often part of the branding of the major confectionery manufacturers and therefore important that is done properly.
One of the machine builders who is specialised in equipment for the food industry, escpecially in aerating, depositing, forming and mixing of fat creams, chocolate and other masses, is Haas-Mondomix. I had the opportunity to visit them in Almere (NL) and work with them on a solution, containing ultrasonic volume flow meters, for adding additives into the main stream of the production process of candy.
