Manufacturing of Casein
There
are two types proteins available in milk basically- Milk Proteins & Whey
Proteins, Milk proteins are called casein, to separate the Casein from Milk pre
separated skimmed milk is required, Coagulation is the process separated casein
and whey from skimmed milk, To coagulate
the milk dosing of acid/ rennet is
required ,
After
coagulation separation of solids and liquid is performed with the help of
decanter centrifuge. Separated solid
mass called casein and remains whey.
Washing
of casein is also required to reduce the acidity and remove the impurities ,
washing is performed in a tank with hot water, Again this water mix casein is
pass threw the decanter to remove the wash water,
After
second stage of decantation this casein transferred to specially designed dryer
for drying.
After
drying casein is packed in 25 kg bags before dispatch.
De-mineralized Whey Powder
Whey
received during the manufacturing of casein is clarified first to separate the
fines particles of casein from the whey; Centrifugal separator is used to separate
the fins from liquid whey.
Pasteurization
of whey is also required to store the whey for further processing; Plate type
heat exchanger is used for pasteurization of whey.
To
remove the water and minerals partially from the Nano Filtration system is
used, This is a membrane filtration system. After passing threw the NF solids
in whey increases from 5% to 18 % and mineral level in whey reduces by 40%.
To
de mineralize the whey more then 40% Electro Dialysis system is used, whey can
be de-mineralized up to 95 % with the ED, degree of demineralization can be
selected from 40 to 90%.
Vacuum
evaporator is used to increase the solid from 18% to 60% good solids in whey
are required for proper crystallization, Crystallization process is required to develop
the non hydroscopic properties.
After
crystallization whey is feed to the dryer to make whey powder, Spray dryer is
used for drying of whey. Whey powder is packed in 25 kg bags before dispatch.
