An apparatus for producing and dispensing a cold product comprises a scraper member operable to scrape a forming wall which is maintained near or below freezing temperature. A substance comprising the product in fluid form is directed to the scraper member and sprayed onto the forming wall during relative movement between the piston member and the wall where it forms a thin layer and the scraper removes the formed product. A cleansing fluid is selectively supplied in one instance to cleanse the apparatus between different substances dispensed, and in another instance, to cleanse and sanitize the apparatus.
