Remark for technics

1. Milk receiving technics

Fresh milk is collected  from milk tank car mostly, a small parts is from leglin. The fresh be tested by

density, acidity, temperature, 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.

2 milk pre-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 ℃ and be feed to mixing tank. Dissolving sugar and feed to sugar tank. Sugar syrup 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 ℃ 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.

3 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 86~94℃, keeping time for 24 seconds, then  go to first effective evaporate room (temperature is 68-70℃) , transferred by pump to second effective room( temperature is 46-50℃). The consistency could be 45%.

4 Spray drying technics

Condensed milk(45%) be transferd by high pressure pump to drying tower. The milk be sprayed to mist state  and meet the hot wind(160~170℃),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 30~35℃ and in powder tank.

5 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.

6 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.

5.7 Control system

All line is controlled by computer with PLC. The main data is flux, temperature and liquid level. All control is done in control room.
