Milk Powder Process System
Powdered milk or dried milk is a manufactured dairy product made by dehydrating liquid milk through several drying processes until it is a powder. One purpose of drying milk is for easy preservation; milk powder has a far longer shelf life than liquid milk and does not need to be refrigerated.
Similar to raw milk, powdered milk is loaded with nutrients; it is a good source of essential minerals and vitamins such as magnesium, calcium, zinc, potassium as well as vitamins A, D, E and K. During the evaporation process, it is ensured that these beneficial nutrients are not lost. Milk powder also meets your daily dose of other important nutritional elements such as amino acids which are responsible for a number of functions such as cellular growth, stimulating the body's immune system, aiding in blood clotting, calcium absorption and so on.
With solutions ranging from 500.000 litres of milk per day up to 2.000.000 litres of milk per day, GENYOND can accompany full milk powder plants. also vary from dairy milk, coconut milk, soybean milk powder etc different product for market.

Milk receiving
Fresh milk is from milk tank car mostly, a small parts is from leglin. The fresh be tested by
density,acidity,tempatature,fat. The certified milk will be filtrate and measured, then be
stored in temporary tank. The milk cooling down by PHE to storage tank or next stage.
pro-processing technics
a. For whole milk powder: milk from storage tank, after measured to temporary tank. Be
transferred to condense stage by pump.
b. For whole sugar powder: Milk from storage tank, be transferred to PHE by pump after
measure. Heating to 45-60 ºC and be feed to mixing tank. Dissolving sugar and feed to
sugar tank. Sugar sirup mixing with milk in mixing tank, and be feed to temporary tank.
c. For whole mixing powder: Milk from storage tank, be transferred to PHE by pump after
measure. Heating to 45-60 ºC and be feed to mixing tank. Dissolving additive and feed to
temporary tank. mixing with milk in tank, after homogenizer in 15Mpa pressure be feed to
temporary tank.
condense technics
Transfer milk(12%) to balance tank of evaporator, heating and to 2ed effective heating room,
then go to 1st effective heating room. The sterilizing temperature is 86~94ºC,keeping time
for 24 seconds. Then go to first effective evaporate room(temperature is
68-70ºC),transferred by pump to second effective room(temperature is 46~50ºC). The
consistency could be 45%.
Spray drying technics
Condensed milk(45%) be transferd by high pressure pump to drying tower. The milk be fog
and meet the hot wind(160~170ºC),become powder quickly and flow down to cone bottom
of the tower, then go to flow bed dryer and mixing with lecithin(1%), the small powder will
be big and drying, cooling down to 30~35ºC and in powder tank.
packing technics
The milk powder be feeded to packing machine by air, after packing in bags and transferred
by conveyer to storage room. Form milk to powder, all of them in closed equipment, So
without any pollution.
CIP system
CIP is controlled by PLC, the liquid level,temperature,acidity is monitored. All
equipment ,piping,valves could by clear by CIP. The evaporator clear by themselves system.
Drying Tower cleared by pressure pump and warm water.
meter and control
All line is controlled by computer with PLC. The main data is flux, temperature and liquid
level. All control is done in control room.
