1.5 Establish Functions

             Table 5: Identified Functions

1	Hold the container.
2	Sensing the grains.
3	Suction of the grain.
4	Grains enter into the machine.
5	Filtering of the grains will take place.
6	Separation of the waste particles and grains will be take place.
7	Outlet of impurities will take place.
8	Collection of grains in a container .
9	Process completion.

Problem definition version 1.3 :-

A semi-automatic grain filtering machine, which is able to do accurate and hygienic filtering process, it should be portable and user-friendly. Machine must not exceed the volume of 1 cubic feet, should be able to clean 1 kg grains per 2-3 minutes, budget to build should not exceed Rs. 3500 and it should work for 3 hours continuously. Machine should indicate the user after filtering process is completed and should not do filtering in case if grains is not there.
