In advanced countries like USA , UK , Australia etc, the quantity of milk procured is high volume from one individual , which is being analysed by milko scanners The milk is received in big carriers and one single sample is taken and paid as per the protein and lactose content.

In India the situation is totally reverse , the milk is received in small quantity from one litre to 500 litres from individuals. The number of farmers are more and the quantity of milk supplied by them is less. Each milk producer must be paid differently depending upon his/her quality and quantity of milk.

So in order to satisfy each farmer (milk producer) the sample of each milk producer must be separately tested and he/she must be paid depending upon the FAT content (quality) and weight (quality) of course. In a co-operative society there may be members as large as 500 who are supplying milk to the society in morning and evening both the shifts. So effectively 500 samples must be tested in a short duration of 2-3 hours.

In early days, Gerber method was popular to test the FAT of the milk. In this method, The fat can be separated from fat-containing milk through the addition of sulphuric acid. The separation is made by using amyl alcohol and centrifugation. The fat content is read directly on a special calibrated butyrometer. This method has some practical difficulties like

  It is important to wear acid resistant gloves, protection glasses or a protection shield.

  Samples containing sugar must not be analyzed by this method. Sugar can react very violently with concentrated sulphuric acid and cause an explosion.

  The sample must be 65°C when reading the fat percentage. If the centrifuge is not adjusted to the right temperature, the butyrometer must be heated in a water bath.

  The procedure requires @ 15 minutes to get the FAT content of a sample so this is too much time consuming

  Acid and Alcohol used are not reusable so testing a sample is too costly.

  A society having 300 samples a day may need to spend @ 3000 Rs a month for that other than Electrical charges.

  To over come this critical and tedious procedure for testing the quality (FAT content) , fat testing machine gives the result in few seconds, Moreover the machine is designed to withstand the hostile rural work environment and also cost effective. Even a village farmer can offord, this fatomatic machine Already thousands of machines are under use for the last 10 years.

Every farmer in the village who owns cows or buffaloes, sells the surplus milk to milk society , which is the part of the milk federation..The milk is individually weighed in the morning and evening shifts and the fat content is determined by the fat testing machine. The farmer is paid as per the fat content rates fixed by the union.

Fatomatic(Automatic FAT testing Machine) has the greatest advantage that it removes all manual error. Conventional handled FAT testing machine has the drawback that the pressure during handle operation affects the FAT result, where as in Fatomatic , the uniform pressure is maintained by motor control, so chances of FAT vaiation is removed completely.

Fatomatic has truly keyless operation in the sense that when a sample bottle is just kept in the place, the IR sensor detedts its presence and starts the motor to suck the sample. During the whole FAT testing operation, the tester need not press any key.
