Abstract: The invention relates to a transfer device for loading and/or unloading a food treatment unit (1a, 1b), with a movable transfer trolley (3) which has a support device (20, 22) for at least one loading rack (27, 28) or for at least one product carrier, with a drive (19) for moving the transfer trolley (3), and with at least one actuator (21, 23) arranged on the transfer trolley (3), which actuator is configured to move the loading rack (27, 28) or the product carrier into a receiving device (25, 26), located on a first side (13) of the transfer trolley (3), of the food treatment unit (1a, 1b) and to remove it therefrom. The task of the invention is to make the loading and/or unloading of a food treatment unit (1a, 1b) particularly flexible, time-efficient and cost-efficient.
