Homemade Multi grain Atta Recipe - 
Ingredients 
Whole Wheat(Punjab Gothumai) - 10 kg Oats - 500 gms
Maize - 500 gms
Ragi - 250 gms 
Chana Dal - 500 gms 
Soya Bean - 250 gms 

If you want cup measures you can have a ratio of 2.5 cups(wheat) : 1 cup(multigrains) We usually grind punjab whole wheat and samba wheat together in the ratio 2:1 for normal chapathi flour. Multigrains - Ragi, Channa Dal, Soya, Oats, Maize and Whole wheat 

Method: 1.Wash all the grains well and let it dry in sunshade for at least for a day till it is completely dry. Then give it for grinding, I gave it to the mill.
2.Allow it to cool for sometime.Sieve it twice and discard the coarse mixture that is retained. while sieving Store in airtight container. 

My Notes: Dry the multigrains completely before giving it to grind. 
Dont add more ragi and soya than the quantity mentioned else it will give a raw taste and ragi will change the color too. 
You can even roast the multigrains(except whole wheat) till a nice aroma rises. Then combine with wheat and give to grind though I havent tried it personally. 
You can even add barley and other grains as per your preference.
