Abstract
An apparatus (1) is used for producing particles of a foodstuff with a fat content of at least 50%, a sugar content of not more than 20% and a water content of not more than 10%. The foodstuff which is present in liquid form can be applied by means of a dosing device (2) in the form of a film or in the form of a strip onto the moved surface of a cooling device (5) with which the foodstuff is at least partly hardenable. In order to enable the production of particles under clean room conditions in an economically viable manner it is proposed that the dosing device (2) comprises a permanently opened pass-through cross section and an elastically deformable membrane (15) which is in contact with one surface with the liquid, sterilized or pasteurized foodstuff. The membrane (15) can be reversibly deflected in a direction approximately perpendicular to its plane, as a result of which the volume of a conveying chamber for the foodstuff can be changed. Moreover, the dosing device (2) and the cooling device (5) are disposed in an encapsulated way within an enclosed vessel (7) which can be sterilized or pasteurized in its interior (24).
