Hi Devkath,
Please approach the National Dairy research Institute in KArnal, Haryana. They conduct trainings on how to start a dairy, set up milk processing plant. Once you get a training you can visit a few dairy nearby for practical knowledge and then with hands on training experience you can start your own processing plant.
The equipments needed are--Milk analysers, automatic milk collection systems, electronic milko tester, milk cans, cream separators etc . All these will be guided to you in the training program.
