INTRODUCTION TO MILK COLLECTION SYSTEM
1.1 INTRODUCTION
While we were in search of problems In the society, with keeping in mind that engineering is a technical solution of a any problem, we decide to look at common man‘s problem. At the same time in month of june11, Milk adulteration problem was on the top of media, so we thought why not explore this problem.

The Dairy industry in India is generally co-operative .The primary milk provided to the dairy are farmers who do not process their milk and give it in the raw form to the co-operative dairy. Since more no. of farmers are depositing their milk in the dairy, it is a daily task of the dairy to assess the quality of milk from each farmer, verify it & meets the quality norms specified and make payments based on quality and quantity of milk. Though several tests are available for quality assessment of milk like the content of protein, water, detergent, lactose, etc. Most dairies use only the fat content test and CLR (Corrected Lactometer Reading) to judge milk quality. Standard ranges of fat content and CLR of milk are specified by the government and it is necessary for the milk to satisfy this quality norms. In measuring fat content we have used the principle of optical scattering of light by fat globules present in the homogenized milk thus diverting totally from the usual method of separating the fat by burning it with acid, centrifuging it and measuring on a calibrated scale In measuring the specific gravity of the milk or the CLR the basic principle of traditional method i.e. using a lactometer is preserved, but the observation of lactometer reading is made using electronics. Use of e-card is an additional feature of this project each farmer is provided with a unique ID number .the daily transactions for each farmer are to be stored on the internal memory as well as on a e-card of the farmer. A e-card reader is installed in the bank preferably in the vicinity of the dairy. There he can withdraw his payment from the bank any time by producing his e-card in the bank. This e-card provision coupled with the portability of the ‗MILK COLLECTION SYSTEM ‘makes it possible to collect milk from those farmers who cannot take their milk to the dairy due to economical, physical, 1

geographical constraints. The milk van equipped with the milk collection system and a weighing scale can collect milk from such farmers.
1.2 A REVIEW OF LITERATURE
The National Dairy Development Board (NDDB) was set up b y the national government in 1965 with a mandate to strengthen and expand the cooperative dairy movement in India. NDDB began operation with the mission of making dairying a means to a better future for millions of grassroots milk producers. Since then, India has emerged as the world‘s largest milk-producing nation. Production has increased by approximately 4% a year, growing from 21.2 million metric tons in 1968 to 84.6 million metric tons in 2001—capable of supplying India‘s very large population with 226 grams of milk per person per day.

Electronic Milko-Tester
The conventional Gerber method takes 2 to 3 hours to ascertain the fat content of milk. This in turn leads to a delay in the payment to the farmer as the payments made strictly on the quality of milk. To overcome this, Milko-tester was developed by a Danish firm that was later modified to Milko-tester Minor, a less complicated version of the Milko-tester III. This model is not only economical but also simple to operate. Moreover, it is suited to village conditions. The greatest advantage of this tester is the accuracy coupled with the rapidity of analysis of fat content. It works on the principle of light scattering with manual homogenization. It operates on AC-mains as well as on battery, with a built-in battery charger and an automatic switch-over to the battery in case of power failure. Rajasthan Electronics...
