The design has three storage units which are fully refrigerated and the fruits can be placed on the top rack. Below that, a pneumatic mechanism is available to pick and place the fruits of required quantity. A mixture and crusher is made available within the machine to ease the mixing process. Mixture will convert fresh fruits into juicy state and crusher will extract juice from the fruits, milk and water ratio will be controlled by the machine. The entire process is controlled using a raspberry pi which is programmed for every movement and functions of the vending machine. A monitor is attached for the selection of the juice and helps to modify the program on the raspberry pi. A biometric setup is attached with the unit for the people who are using the machine regularly. Overall, the fabricated machine becomes alternative for the soda vending machines, and it can change the morality of the people for drinking fresh juice then and there with a hygienic preparation.
