     Principles

    The hot air enters into the bottom of the dryer in tangent direction. Under the driving of the stirrer, a powerful rotating wind area is formed. The paste state materials enter into the dryer through the screw charger. Under the powerful function effect of stirring at high-speed rotation , the materials are distributed under the function of strike ,friction and shearing force. The block state materials will soon be smashed and contact the hot air fully and the materials are heated and dried. The dried materials after the de-watering will go up with the hot-air flow. The grading rings will stop and keep the big particles. Small particles will be discharged out of the dryer from the ring center and will be collected in the cyclone and dust collector. The not-fully-dried or big piece materials will be sent to the wall of the equipment by centrifugal force and be smashed again after they fall down to the bottom.
    For the feeding system , normally , Hywell choose double screw feeder .Double Shaft with Specially Designed Blades for lumps break as to ensure the raw material into the drying chamber smoothly . And drive Through motor & Gear Box.

    For the dust collecting system, it has several ways The Finished product collected is using cyclones, and/or bag filters. Typically, cyclones are followed by scrubbers or bag filters for final cleaning of the exhaust gases to meet current emission requirements.


    Feature

    1.When oil is used to heat, use automatic constant temperature control. Its temperature of operation can be adjusted form 80-160 .

    2. Machine materials : AISISUS304 , AISISUS316L, and other material .

    3. The feeding system for this machine can be screw feeder .

    4. For the electrical component  , we mainly use international brand such as ABB ,Siemens or Schneider. Control system has more choices, such as push button , HMI+PLC and so on.

    5. Highly polished inner and outer surfaces of the machine, no dead comer, easy to clear, no cross contamination. Smooth running, reliable performance, easy operation.

    6.The collection rate of finished product is very high.
    To adopt cyclone separator with high efficiency and low resistance (the collection rate can be above 98%), together with air chamber type of pulse cloth bag duster(the collection rate can be above 99.9%).

    7.To control final water content and fine of finished product efficiently
    To control final water content and fine of finished product through adjusting screener and inlet air speed.

    8. No materials stick on the wall
    Continuous high-speed air flow washes out the materials stayed on the wall strongly in order to clear the phenomenon that materials stay on the wall.

    9. This machine is good at processing thermal sensitive materials, The bottom of main machine belongs to high temperature area. The air speed in this area is very high, and the material can hardly contact heat surface directly, so there is no worry about burning and color changing.

    10. Wet material is dispersed into a stream of heated air (or gas) which conveys it through a drying duct. Using the heat from the airstream, the material dries as it is conveyed. Product is separated using cyclones, and/or bag filters. Typically, cyclones are followed by scrubbers or bag filters for final cleaning of the exhaust gases to meet current emission requirements.

    11. The feed system consists of a feed vat where a discontinuous flow of product is buffered and fragmented by an agitator prior to continuous drying. A variable speed feed screw (or pump in the case of fluid feed) forwards the product to the drying chamber.

    12.The rotor at the conical base of the drying chamber fluidizes product particles in a drying-efficient hot air flow pattern in which any wet lumps are rapidly disintegrated. Hot air is supplied by a temperature-controlled air heater and speed-controlled fan, entering the drying chamber at a tangent in order to establish a turbulent, whirling air flow

    13. Airborne, fine particles pass through a classifier at the top of the drying chamber, while larger particles remain in the air flow for further drying and powdering.

    14. The drying chamber is rigidly designed to withstand pressure shock in the event of explosive combustion of flammable particles. All bearings are effectively protected against dust and heat.

     

    Application
    SXG Series Flash Dryer is widely used in light industry, chemical industry, foodstuff, agricultural products, powder, granule, and small block material in pharmaceutical industry. Material examples are as following: HPAM, feed, hypha protein, sodium sulfate, plastic archon, catalyst, stripping and slicing potato, baking soda, detergent, quartz sand, soybean billet, ban pulp, metal powder, boric acid, sodium borate, activated clay, compound fertilizer, eat.

    Optional Choices
    1.For the main electrical components , we have international brand choices such as ABB , Siemens or Schneider or others.
    2.For the material for the machine , we have choices onAISISUS304 , AISISUS316L,carbon steel and so on .
    3.For the control system , we have choices on push button, PLC+HMI and so on .
    We can design the explosion-proof system for the dryer based on the customer request.
    4.For the fitting system for the the dryer, we can supply it. such as feeding system , pneumatic conveying system and so on.
    5.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 dryer.


    Attention to order

    1. When order the SXG series flash drying machine, Client need to supply the materials name.

    2.When order the SXG series flash drying machine, Client need to supply the materials characteristic that include materials HP, Maximum withstand temperature and so on.

    3.When order the SXG series flash drying machine, Client need to supply the materials primary moisture and final moisture (%).

    4.When order the SXG series flash drying machine, Client need to supply the treating capacity per hour.

    5.When order the SXG series flash drying machine, Client need to supply heating way, if it use steam heating, client need to supply the steam pressure and steam capacity.

     6.When order the SXG series flash drying machine, Client need to decide which kinds steel for machine-304 stainless steel or 316L stainless steel (Hywell also give suggestion for the stainless steel model base the materials HP).
