摘要:
Described is method for cleaning a machine (1) for liquid or semi-liquid food products, the machine comprising: at least one container (2) forming a processing chamber intended to convert a basic mixture into a finished product and provided with a mixer (8) inside the processing chamber; thermal treatment means (4) intended to exchange heat with the processing chamber, the method comprising, in combination, the following steps: a) pasteurising the basic mixture or finished product in the container (2) at each predetermined first time interval; b) performing the following sequence of operations at each predetermined second time interval: emptying the basic mixture contained in the first container (2), washing the first container (2) using a washing fluid, filling at least partly the first container (2) with a cleaning fluid and subjecting the cleaning fluid in the first container (2) to a heating thermal treatment; c) disassembling and cleaning at each predetermined third time interval at least part of the components of which the machine (1) consists and which are intended to make contact, in use, with the basic mixture or with the product, where the first time interval is less than the second time interval and the second time interval is less than the third time interval.
摘要:
Described is a machine (1) for making liquid or semi-liquid food products comprising: a frame (2); a plurality of first containers (3) containing a liquid or semi-liquid basic mixture and having a deformable wall (4), in such a way that the space occupied by each first container (3) depends on a quantity of basic mixture in the first container (3); a rigid second container (5) forming a processing chamber for the basic mixture and equipped with a mixer (6) and means (7) for thermal treatment of the basic mixture, operating in conjunction with one another to convert the basic mixture into a liquid or semi-liquid product; means (8) for connecting the first containers (3) to the second container (5), configured to allow connection of one of the first containers (3) to the second container (5) and for transferring the basic mixture from one of the first containers (3) to the second container (5); means (9) for supporting the first containers (3), operatively associated with the frame (2), at least one sensor (10) configured for making available a signal representing the quantity of basic mixture at least in one of the first containers (3) operatively connected to the second container (5); a command and control unit (11), connected to the sensor (10) to receive the signal and configured to infer, based on the signal, a condition of absence of mixture in one of the first containers (3) connected to the second container (5).
