YPG series Pressure spray (cooling) Dryer

  

  

Test  

Because of different products have different drying technologies and particle rules, there is no single type of the spray drying machines that meet all kinds of different requirements. Now spraying is still regards as a kind of technology. The test is the base of correctly choosing the types. The machine equipped by the "YIBU" Company is used specially for the carry out the technological test of the materials. This kind of practical manner makes that we have completed many turn-key projects, such as: detergent powder, polymerized resin, white carbon,Mn3O4,soybean milk, lipase, sea cucumber Chinese traditional medicine and etc. 

  

Product Description
This equipment combines drying and granulating two functions together. 
The needed ball granule with certain size and ratio can be got in accordance with requirements of process to adjust pressure, flow, and size of atomizing hole..

        

Principle 

The working of the pressure spray dryer as follows:

the liquid of raw material is pumped in through diaphragm pump. The liquid of raw material can be atomized into tiny droplets. Then it gathers with hot air and falls off. Most parts of powder material will be collected  from the  the outlet of the main tower bottom . for the fine powder , we will still continuously collect them by the cyclone separator and cloth bag filter or water scrupper . but it should depend on the material property .

For the pressure spray dryer , it simply has bellow system :

1.Air inlet system   it consists of air filter (such as Pre&post filter&Sub-high efficiency filter and high efficiency filter) , air heater (such as electrical heater ,steam radiator ,gas furnace and so on )  draft fan and relative air inlet duct .
2.Liquid delivery system it consists of diagraph pump or screw pump ,material stirring tank and relative pipe .
3.Atomizing system : pressure pump with inverter 
4.Main tower. it consists of the conical sections , straight sections , air hammer , lighting device , manhole and so on .
5.Material collecting system. it consists of cyclone  separator and cloth bag filter or water scraper  .this parts should be equipped based on customer needs .

6.Air outlet system . it consists of suction fan ,air outlet duct and post filter or High efficiency filter.(for the filter chose , it is based on the customer request.)

The tower body, pipes and separator of set where will contact with the product are made of AISISUS304 or AISISUS304L or AISISUS316L or AISISUS316. There is enough layer of heat preservation between inner and outer case of the drying tower body. The filled material is fine glass cotton. The tower body we also equipped with observation door, sight glass, lamp-house and control meters and instruments that is controlled and displayed through electric control panel.

            

   

Features
1.high collecting rate
2.no stick onto the wall 
3.fast drying 
4.energy saving 
5.high efficiency 
6.especially applicable for heat heat sensitive material.
7.For the heating system for the machine , it is very flexible. we can configure it based on the customer site conditions  such as steam ,electricity , gas furnace and so on , all of them we can design it to match our spray dryer.

8.Control system has more choices, such as push button, HMI+PLC and so on
