What does it have to do with politics or you want to supply branded flour to politicians during campaigns?Anyway,5 acres is more than enough.Alpha Millers the makers of Kifaru maize fluor sits on approximately 3 acres next to Nakumatt Embakasi and if handled well it is a good business.For the machinery,google for Buhler who are manufacturers.

I am planning to venture into both maize and flour milling business ...... what is the capital investment like?
Depending much on what grade and the rated outputs, where the machines are from( chinese or SA. Level of automation
Cheapest from china about 2M or but from SA cheapest was 6M.
What machines do i need?
Degerming, Sorting, griding and packing Might need silos for bulk storage but you still can scale it down.The best is to visit the ASK show there is a chinese company that operates from there and they will give a demo. And take you through the proccess.

Any idea where i can get the machines at fair prices?

Depends much on you expected outputs ( grade) and capacity for the machine (how many kgs per hour). If you go chinese less that 2M but without packing machine, will only be able to pack from 5kgs upwards. A different machine to pack on paper. If you go Roff from SA upwards of 7M. Write to them they are very responsive and you will get quotes almost within a day.

Chinese or european machines - which are the best?
Chinese will do the job but you need not long lasting. The european ones very expensive and overated but are long lasting for entry level i say chinese

Is 5 acres of land enough for this enterprise?
More that enough.
Advice / ideas so much welcome!!

@Mjuaji,
Sorry to hijack your thread..can someone say something on what would one require to setup an animal feeds plant..would it be cheaper or more expensive as compared to a milling plant?

@ Chaka- Animal feeds making is milling ( a milling machine) and mixing ( mixing machine). So all what you need to have a feed factory is a a milling and mixing machine.
