Visit to Milk and Milk Products Processing Plant

Objectives:

 To study various operations of milk processing in the plant.

Relevant information:

The modern concept of dairying denotes and organized way of reducing, processing and marketing of milk and milk products. Dairying is an industry in India and its growth started from the plan periods. During the last two or three decades Govt. of India have established milk schemes in Urban areas. Milk is collected from rural areas and transported to city milk plants quickly under hygienic conditions. It is then subjected to different process like filtration clarification, standardization, homogenization, pasteurization and packing before its distribution to consumers. What are the organizations and operational structures of this process are the aspects of study visit to Dairy plant.

Precautions:

1. The parts of machine should not be touched knowing their know – how.
2. Beware form electrical circuit and connections. Be careful about points of steam leakages and open points. While handling the machine consult / take the help of operator.
3. Project yourself from conveyor chain or machinery chain. Do not be over enthusiastic.
4. Avoid accident.
