DRYER OF WHEAT MAIZE FLOUR GERMS BRAN (FOOD POWDER TYPE MATERIAL ONLY)

DRYER OF WHEAT MAIZE FLOUR GERMS BRAN FEED for Wheat maize sorghum, millet semolina, Nshima,Adda, Maida.

This kind of dryer for flour bran germ (food powder) type of material only, Special designed for flour, bran and wheat maize germs 

to ensure produce finest quality of flour bran and germs.

Features show:

➢ Programmable logic control system to ensure stable drying effect.

➢Unique drying tunnel and spontaneous steam design, prolong drying time, energy-saving effect is remarkable.

➢Lower drying temperature, no change in material color and quality after drying.

➢ Conduction and airflow mixed heat transfer mode, the material is heated quickly, uniformly and sufficiently.

➢The temperature of the material after drying during the cooling process is close to the ambient temperature, and the 

    low temperature packaging is conducive to storage.

➢ Program fault self-test, stop abnormal equipment and alarm to prevent equipment damage.

➢ Humanized parameter setting, suitable for more milling processes.

WORKING METHOD:

The main components of the drying system:  automatic valve, dryer, air closer, fan, dust collector, pulse air flow drying pipe, 

pulse air flow cooling pipe, drying cyclone, cooling cyclone, chute, air duct.

Pneumatic valve controls whether the material enters the drying system. 

1. Dryer is a device that evaporates the water in the material.

2. Pulse air flow drying tube is used to separate the material from the water evaporated in the material.

3. Drying cycloneis used to separate the material and the air for drying.

4. Pulse air flow cooling pipe uses fresh air to cool the material, to ensure that the material packing temperature is 1-3 degrees Celsius

5. higher than the ambient temperature.

5. Cooling cycloneis used to separate materials and cool air.

6. Air closer are used to seal air through the material.

7. Fans power the flow of air throughout the system.

8. The dust collector is used to reduce the dust content of the exhaust gas to be discharged into the atmosphere.

9. The chute is used to transport materials into the corresponding equipment.

10. The air duct connects the cyclone, the dust collector and the fan, which is the channel of air and transmits the power of the fan.

11. 
    

Function of each parts as following:

1. Host and valves, equipment, pipelines, etc

      Feed valve, dryer, pulse air flow drying pipe, drying discharger, pulse air flow cooling pipe, cooling discharger, fan, damper, 

      dust collector.

2. Temperature sensor

       Each set of dryers has 5 temperature sensors, which can reflect the temperature of each key part to the screen in real time; The 

      measured temperature is compared with the set temperature to control the heater output power; Monitor the temperature of critical

      areas to ensure that the equipment is operating at a safe temperature.

3. Level sensor

        Each set of drying unit has 4 material level sensors, which monitor whether the key position of the pipeline is blocked, and transmit 

      the material level signal to the PLC to participate in the control to ensure that the equipment is not overloaded due to material plugging.

4. Automatic control cabinet

    The automatic control cabinet is the control center of the drying system, and all equipment operation, valve action, fault alarm and 

    shutdown are controlled by it.

5. Equipment on-site control box

The equipment that can be controlled on site in the system includes: dust collector scraper motor, dust collector air closure motor (2),

fan motor, damper solenoid valve (AC220V), discharger motor, feed valve, solenoid valve (AC220V), dryer motor.

NR series 8th generation grain flour bran germs DRYER is composed of two parts: drying drum and air preheating box, the air preheating 

box is in the upper part and the drying drum is in the lower part. The air is heated by the air preheating box and fully mixed with the material

 in the drying drum to contain the water evaporated from the material. The drying drum is the device that plays the main role in the whole 

drying process, which provides heat for the evaporation of water in the material, and at the same time allows the material and air to be fully

 mixed, so that the water inside the material evaporates into water vapor.

The inner cylinder and outer cylinder of the drying cylinder provide heat for the evaporation of the material moisture continuously and 

quickly when the material passes, so that the moisture inside the material diffuses to the surface of the material, and the material and the

 surrounding air come out of the drying drum into the pulse airflow drying tube Due to the disturbance of the airflow, the moisture on the 

surface of the material quickly diffuses to the surrounding air and separates from the material, and the material at the drying Sacron is 

separated from the air containing a large amount of water.

The whole set of drying system adopts PLC programmable controller centralized control, independent research and development of drying

 control program can automatically compensate heating power according to the ambient temperature, to ensure the stability of drying water,

 can be set timing drying, constant temperature drying, constant humidity drying, etc., the system can automatically detect temperature, 

material level, fault, etc., the operation panel adopts a large size color touch screen, can intuitively display the operating status, temperature,

 fault, etc. of each equipment of the system.
