Detailed Product Description
Milk powder plant comprise following components :
1.Multiple Effect Falling Film Energy Efficient Evaporator
2.Energy Efficient Spray Dryer
3.Vibro Fluid Bed Dryer Cum Cooler as Second Stage Dryer
4.CIP Cleaning system
Normally Raw material is defatted milk (raw liquid) , the solid containing variety between 8.5%--9%; water containing of the product is at the common level; the quantity of defatted milk to deal with is ranged from 50 KG up to 10000kg / h.
Some issues must be considered while designing
In order to enhance the using rate of energy while drying, the defatted milk should be evaporated by vacuum evaporator before spray drying to get the solid containing at the level of 45%. The evaporator we adopt is Double Effect Forced External Circulation Vacuum Evaporator .
Because the heat required for drying process is great , so it is not suitable to adopt electric heater, and indirect diesel-fuel hot air generator. And the water vapour produced by burning is mixed into the hot air. Bases the experience, the moisture containing get into the spray tower is 0.03kg(water)/kg(air)
Heat exchanger in the hot air generator is made of stainless steel. Hot air must be filtrated and purified by primary filter before get into heat exchanger. Heated air must be filtrated by middle efficient filter before get in touch with raw liquid. All the fans will be made of stainless steel .
Adopting the obey-current drying method, the spray tower is under tiny negative pressure. For the shape of the final product is hollow-ball granule with good fluidity and solubility, so we choose YPG series high pressure spray dryer.
The part contact with raw material and product is made of Stainless steel , the outside surface and all the connecting flange is made of stainless steel. The surface of the main tower , cyclone and inner pipes should be polished after welding.
Two stage Cyclones are equipped to collecting milk powder, it is not suitable to use bag dust filter.
Automatic discharge valves which are made of stainless steel will be equipped at the bottom of spray tower and cyclones.

CIP Cleaning system:
Working principle:
CIP system is one of the prerequisites of food pharmacy production sanitary standards. it can remove the active mixed pollution and insoluble particles of impurity ,reduce or remove the micro chemicals and heat source that pollute the productions. GMP requires CIP system in food and pharmacy industry, which limits related industries because the high expense in overseas completely automatically CIP system .The specialists in our company import and digest international advanced technique ,and successfully make automatically CIP system with high automation, simple operation, and reasonable price. Performance characteristic Flexibility and general usage The system can undertake single process such as acerbity cleaning, alkali cleaning, and hot water cleaning, and also can take completely automatic cleaning according to the cleaning process designed. Besides, it can control the growing of micro chemicals. Half automatic or complete automatic equipments can be made to order. Safety and reliance Dense acerbity liquid and alkali liquid are in the berried acerbity pot and alkali pot; the liquid position is automatically controlled, fixed with overflow protecting system; and unique material outlet construction can stop crystallization from the cleaning liquid to stop the pipe Economics and high efficiency This equipment greatly reduces the cleaning time and increase the work efficiency compared with cleaning by hand; the use of cleaning liquid and water is more reasonable; meanwhile steam cost id relatively small, so to make full use of energy, and reduce the cleanincost. Matured PLC controlling system: Years of experience accumulation enhances the programs. Imported qualified controlling part can keep the system operate steadily for along time; friendly interface between people and machine shortens the training time of the operators, and shows directly work condition of key parts of the machine; easily understandable interface can cooperate the operator the make decision, and deal with the common problems, so to ensure the machine return to work in time
