This allows to position the cassette 10 in a beverage preparation device 1 in only one possible orientation using an (extending) connection part 2 of the beverage preparation device 1 , as is illustrated in the schematic view of the embodiment shown in Fig. 2.
  • a beverage preparation device 1 comprising a connector part 2 for receiving a cassette 10 according to any one of embodiments described herein.
  • the connector part 2 comprises a first interface 6 for driving the dosage unit 20 (more specifically the drive connection 22), a second interface 7 for driving the mixing unit 30 (more specific the second non-mechanical link 31) and a water input interface 8 for connection to the fluid inlet 32.
  • the beverage preparation device 1 further comprising a control unit 3 connected to the first interface 6, second interface 7 and water input interface 8.
  • control unit 3 is arranged to provide a time period between ending the first interface drive signal and the water input interface signal, allowing to rinse any possibly beverage ingredient 5 from the mixing bowl 27 further into the mixing unit 30.
  • the control unit 3 is connected to a reader unit 4 in a further embodiment for receiving data relating to the product in the cassette 10, and to control the first interface 6, second interface 7 and water input interface 8 depending on the received data.
  • control unit 3 is arranged to control an operating speed of the first interface 6 for driving the feeder device 21 . This allows to control the dispensing process of the beverage ingredient 5 of the beverage preparation apparatus 1 very accurately, and allows to provide a constant quality of the dispensed product, even when various quantities of beverage ingredient 5 and water are being used.
  • the connections 22, 31 , 32 of the cassette 10 are also oriented in a single direction in an embodiment, allowing e.g. a linear shifting movement of the cassette 10 towards the beverage preparation apparatus 1 to make the connections with corresponding terminals in the beverage preparation apparatus 1 .
  • the beverage preparation apparatus 1 can thus be a very simple design, comprising only the control circuitry and drive control mechanisms for the supply of the fluid, dosage of the beverage ingredient 5 and drive of the mixing unit 30.
  • a further embodiment of the cassette 10 is shown in a partially transparent side view (which would be possible when using a transparent plastic material for the cassette elements). Internal elements are shown in striped lines.

  • the disc shaped device 28 is driven at its edge or rim by the feeder device 21 , e.g. using cogs 42 as shown in the embodiment of Fig. 3.
  • Fig. 4 shows a detail of the top part of the cassette 10, where the optional lid 1 1 is provided for closing off the supply compartment 10a.
  • the lid 1 1 can be removed for cleaning the inside of the supply compartment 10a and for refilling the supply compartment 10a.
  • the lid 1 1 is in a clamping arrangement with the edge of the supply compartment 10.
  • a sealing band or tape can be used to enhance the sealing of the cassette 10.
  • All elements inside the supply compartment 10a e.g. the anti-compacting device 28, can be taken out in a further embodiment in, such that a supply compartment 10a remains with straight surfaces that can be easily cleaned.
  • a similar embodiment may be provided for the mixing compartment 10b, where e.g. the mixing unit 30 can be easily removed, e.g. for cleaning or replacement purposes. These embodiments also allow preventive maintenance at a central location, away from the beverage preparation device 1 .
