A GLANCE ON DAIRY
5
Daily Activities.
•Collection of milk from nearby places and different societies.
•Milk is poured in dump tank.
•Milk testing is done for calculating Fat and S.N.F in milk by
taking samples.
•Then Pasteurization is done to kill the bacteria and other
microbes present in milk.
•Chilling is done at <5°C temperature for 1 hour with a
capacity of 10,000 liters milk/hr in ‘Plate chiller’.
•Then milk is packed in Polythene sachet.
•Several other milk products are also made.

•₹280 is paid per kilogram of Fat and ₹186 is paid per kilogram of
SNF part in the milk
•Amount is paid on weekly basis in the bank accounts of societies
•Money can be withdrawn only when signature of both incharge and

Datewise comparative milk sale report
(January)
42
• Leakage loss was 1.0 to 1.5 per cent in the polythene packs.
• Crate leakage was 0.1 per cent.
• Vehicles going to Bageswar (80-km from Almora) depicted leaking
problems higher than average due to friction in crates.
• There were two prominent seasons when demand supply fluctuations
were very prominent. From Oct-Jan, production was more and henceforth
supply was more but demand was less. Hence, excess milk was supplied
to Mother Dairy via NMG agreements at lower prices. This led to a crash in
procurement
prices from farmers and paved the way for farmers demotivation.
• From April to June, milk procurement decreased due to decline in
productivity but demand increased and rates started skyrocketing. Again,
this led to entrance of private players in the market for earning more profits
through the channel.
• The margins provided to the agents were not sufficient.
MARKETING RELATED PROBLEMS

LABORATORY
TESTS
44
Procedure
•Open the can of milk.
•Smell Immediately.
•Observe the appearance.
•Taste but do not swallow the milk.
•Check cleanliness of the can lid and milk can.
If everything is up to the mark the batch is passed.
1. ORGANOLEPTIC TESTS
45
Procedure
•Mix equal amounts of milk and 68% of ethanol solution in a test tube
(Usually 2ml each is taken).
•68 % Ethanol solution is prepared from 68 ml 96% (absolute)
alcohol and 28 ml distilled water.
•Good quality of milk will show no coagulation, clotting or
precipitation, but it is necessary to look for small lumps.
2. ALCOHOL TEST
46
Procedure
•Boil small amount of milk in a test tube
•Clotting, coagulation or precipitation of milk shows the failure of the
test
•Heavy contamination in freshly drawn milk cannot be detected,
when the acidity is below 0.20-0.26% Lactic acid
3. CLOT ON BOILING (C.O.B)
TEST
47
Procedure
•Pour the preliminary prepared sample in the sample holder of the
analyzer
•Put the sample holder in the recess of the analyzer
•Press the enter button
•The analyzer sucks the milk, makes the measurement and returns
the milk in the waste liquid reservoir
4. LACTOSCAN
48
Procedure
•Measure 10 ml of the milk in the conical flask
•Add 1 drop of Phenolpthalein
•Add 0.1N Sodium Hydroxide from burette under continuous mixing,
until a faint pink colour appears
•Volume of Sodium Hydroxide solution consumed is used to express
the percentage of lactic acid
5. ACIDITY TEST
49
Procedure
•Add 10 ml sulphuric acid to the butyrometer followed by 10.94 or 11
ml of milk
•Add 1 ml of Amyl alcohol, insert stopper and shake the butyrometer
•Place the butyrometer in the water bath at 65ºC and keep it there
until a set is ready for centrifuging
•Spin for 5 minutes at 1100 rpm
•Remove the butyrometers from the centrifuge
•Put the butyrometers in a water bath maintained at 65ºC for 3 min.
before taking the reading
6. FAT DETERMINATION BY
GERBER METHOD
50
Procedure
•Mix the milk sample and pour it into a measuring cylinder
•Put the Lactometer and allow sinking slowly into the milk
•Read and record the last Lactometer degree (ºL) just above the
surface of the milk
•If the temperature of the milk is different from the calibration
temperature of the lactometer, calculate the temperature correction
•Calculate SNF and TS content of the milk with the help of lactometer
reading
7. SNF DETERMINATION BY
LACTOMETER TEST
51
•Different adulteration tests are performed only when procurement is done
from sources other than trusted societies
•Performed with the help of adulteration kit
•Different adulterants that can be identified are –
–Urea
–Ammonia
–Fertilizer
–Pond water
–Starch
–Sugar
–Glucose
–Salt
–Neutralizer
–Peroxide
–Maltose

•2.5 to 3 kilograms of Caustic is mixed with 700-800 litres of
potable water
AcidPreparation
•35-40 litres of Nitric Acid are mixed with 700-800 litres of
potable water
55
TIMINGS OF CIP
Done before and after each batch of milk
processing
Done four times a day
Morning shift CIP involves cleaning of whole plant
and takes one hour
Other CIPs take half an hour each
Potable water treatment is done at the end of the
evening shift
56
METHODS OF CLEANING
EQUIPMENTS
1. For plate heat exchangers and pipes, solutions are
passed in a pre-defined manner using pumps
2. Silos are cleaned using Spray Balls located on the
upper side which sprinkles solutions under pressure
which cleans it thoroughly
57
1. Milk cans are cleaned through can washer and rinsed thoroughly by
potable water
2. Cream separator, butter churner, raw milk dump tank, etc. are
dismantled and cleaned manually
