I am a coffee owner and would like to have a product designed that will serve as a dispenser of ground material (turkish coffee (very powdery), nescafe, and hot chocolate cocoa (also very powdery)). the objective is to control the weight that is being used. I think it will use quite a lot of the functionality found in on-demand espresso grinders where there are timers that the user uses to specify the length of time that the grinder will grind and dispense coffee beans for. I just need the timer and suction functionality for this product. The product will be calibrated each day to make sure that the same weight is being dispensed given the timer settings but nonetheless they should be designed to be very consistent and reliable. in terms of the container that will house the material, it should not be too big and it should be removable. the whole product will be mounted on the wall just like a hygiene dispenser
