  Product introduction of air dryer:

     The airflow dryer is a hot air pulse dryer, also known as a hot air pipeline dryer. The advantages of this dryer are direct heating, fast drying, foldable installation, and space-saving.

     The airflow dryer allows the wet raw material to mix with the high-temperature airflow, and the moisture is separated from the raw material through the separator. The dryer is widely used in food, feed, chemical, pharmaceutical, mining and other industries. The working process of the drying equipment is as follows: After the dehydrated wet material is added to the dryer, the material is dried under the stirring of the evenly distributed lifting plates in the pipeline. Evenly disperse in the machine and fully contact with hot air to speed up heat transfer and mass transfer in drying. In the drying process, the material is under the action of the inclined lifting plate and the hot air. As for the dryer, a star discharge valve is added to discharge the finished product. The working principle of the airflow dryer is to send the granular wet material into the hot air. , and co-flow with it, so as to obtain granular dry products, which has a good effect on opening up feed resources, reducing feeding costs, and reducing environmental pollution.

  

Performance characteristics of airflow dryer:

1. Dry raw materials: rice husk, sawdust, crushed soaked flowers, branches, wood chips and other granular raw materials (diameter less than 3mm, length less than 5mm). 2. Production efficiency: when the hot air is 180°C, dry sawdust or rice husk with a relative humidity of 35% to a relative temperature of 10%. The hot air temperature is not lower than 180°C and can reach 300°C.

3. The fuel can be selected: firewood (broken firewood), coal, steam or electric heating.

     The airflow dryer uses the principle of instant airflow drying, which has the characteristics of high drying strength, short drying time, low energy consumption, easy operation, and good product quality. The starch dried by this equipment has the advantages of clean appearance, luster, high fineness, stable water content and less impurity pollution. The airflow dryer is an ideal equipment for drying powdery, flaky and heat-sensitive materials in industries such as starch, rice flour, food, medicine, and chemical industry. The use of this equipment can quickly obtain good returns with small investment, low energy consumption, less manpower and less space.

 

Brief introduction to the structure of the airflow dryer:
 Usually the moisture content of the raw materials we purchase is between 30%-60%, the moisture content of the sawdust just out of the saw board room is 80%-100%, and the moisture content of the raw materials after good air-drying and drying can be reduced to 20%. or so, but still not up to the mark. The ideal moisture content should be between 8% --- 13%. However, the moisture content of raw materials has never been measured in actual production. Because that's cumbersome and has a time lag. Because the drying intensity of the dryer for raw materials is not uniform and stable, every time the furnace door is opened to add fuel, the temperature of the pipeline will drop rapidly due to the entry of cold air, and the addition of raw materials is very frequent during the entire drying process. Therefore, it can be judged whether the water content is qualified by vision and feel. Generally speaking, the appearance of the raw material is burnt yellow, and if it looks oily, it means that its water content is qualified. The further verification method is to grab a handful of raw materials with your hands, hold them tightly, and then let go to see if the raw materials can be natural. Spread evenly. The above is the usual inspection method. In fact, it is the molding machine that determines whether the moisture content of the raw material is qualified. As long as qualified rods can be extruded from the molding machine, the moisture content of the raw materials is in line with the requirements. The key to raw material drying lies in the control of furnace temperature, which requires workers to adjust the furnace temperature in time according to the different appearances of raw materials.

 

 

 

 

Main features of airflow dryer:

1. The drying strength of the airflow dryer is high: due to the high airflow velocity, the material is well dispersed in the gas phase, and the entire surface of the material can be used as the effective drying area. Therefore, the limited drying area is greatly increased. At the same time, due to the dispersion and agitation during drying, the vaporized surface is constantly renewed, so the heat transfer process of drying is intensive.

2. The drying time of the airflow dryer is short: the contact time between the material and the air is short, and the drying time is generally 5-5 seconds. For heat-sensitive or low-melting point materials, it will not cause overheating or decomposition to affect its quality.

3. The thermal efficiency of the airflow dryer is high: the airflow drying adopts the parallel flow operation of the material and the gas, and the temperature of the material and the air can reach a reasonable state from the beginning to the end, and the drying time is short, so a higher drying temperature can be used.

4. The airflow dryer has a wide range of applications, high output, and large precipitation; simple structure, small station area, and low investment and maintenance costs.

5. Source of hot air for airflow dryer: oil furnace, gas furnace, coal-fired hot air stove, steam heat exchanger.

Operating procedures of the air dryer:

1. After the installation is completed, turn on the fan, check the rotation direction of the fan and whether the suction of the feeding port is normal.

2. Check the joints of each flange to see if there is any air leakage.

3. Bind the cloth bags with both ends open on the discharge port of the separator.

4. Add the material to be dried at the feeding port, and large particles must be screened out before drying, which is conducive to improving the drying speed.

5. Add fuel into the furnace, turn on the fan, and when the temperature at the air outlet reaches 150°C, start cutting and drying.

6. Timely remove the bulky material at the slag outlet for easy feeding.
