ABSTRACT:
A machine (100) for the treatment of pharmaceutical products (P) comprises a pan (2) that revolves about an axis of rotation (X) and a dispensing unit (3) designed to disperse a coating material inside the pan (2) over a mass (M) of the products (P) located in the pan (2). The pan (2) has an opening (7) for feeding the products to be treated (P) into the pan (2), and an opening (8) for feeding the products (PT) already treated with the coating material out of the pan (2), the infeed opening (7) and the outfeed opening (8) being separate and independent of each other. A portion (K) of the inside surface of the pan (2) is equipped with at least one helical flow regulating fin (4, 5, 6) designed to facilitate inflow (F3) of the products to be treated (P) into the pan (2) during the feeding of the products (P) into the pan (2) through the infeed opening (7) when the pan (2) itself revolves in a first direction of rotation (FI), and to cause outflow (F4) of the treated products (PT) from the pan (2) during the outfeed of the treated products (PT) from the pan (2) through the outfeed opening (8) when the pan (2) itself revolves in a second direction of rotation (F2), opposite to the first direction of rotation (F1).
