This machine should should not be larger than an a4 paper in size and it should seperate the coffee remnant inside a used coffee capsule from the capsule. it will be power by a small motor which does all the steps except the loading of the used coffee capsules which should be done manually. please i need all the help and ideas i can get in building it/operating diagram.. i have to use a motor (Ref. SC31ZY-DC) that has a torque of 4.5 Nm at a speed of 7.5 min-1 (under load). Thanks for all your help in advance.
