Soya milk powder making process with spray dryer machine

The simple of making soya bean milk powder is as following,

The raw materials would be used contains : 80-82% dehulled high-quality soybeans, appropriate amount of water, and other nutrient substance ;

General Process: 

(1) The well sorted out high-quality soya beans are sent to the soya bean dehulling machine, and then sent to the water tank to soak in cold water for 3-4 hours, then drain the cold water, and then add 80-85°C hot water, keep warm and soak for 5-6 hours, then drain the hot water;
