What is the Flash Dryer?
The flash dryer is a type of drying machine that uses high-temperature air flow to dry materials with high moisture content. This is one of the most efficient methods that can help you dry the feed within seconds.
How the Flash Dryer Works?
Step 1: Feeding
The first step is to feed the wet material into the feeding system of the flash dryer. Different types of materials have their own properties. You can choose a screw conveyor, a screw feeder or a rotary valve to send your material into the flash dryer.
Step 2: Intake
Then let the hot air into the drying chamber from the tangential air intake at the bottom of the flash dryer. The wet material will get into the high-speed hot air flow and the intense mixing, grinding, and stirring zone.
Step 3: Evaporation
After the material touches the hot air, the high-humidity material in the button of the flash dryer will be crushed by the blender. At the same time, the low-humidity materials on the surface will be driven up. The temperature and speed of the hot air are controlled accurately. This will form an intense heat transfer. And the material moisture will evaporate rapidly.
The turbulence helps to ensure the drying is even and prevents clumping. If you want to dry the slurry or paste form materials, then you can equip an atomizer or nozzle to atomize the material into tiny droplets; it’s a useful method to improve the drying efficiency.
Step 4: Micronization
Under the high-temperature environment, your wet material will be shearing, blowing, and mixing. Then the material will be micronized under the influence of the centrifugal force. During this period, the gas phase and the solid phase will undergo the rotational flow. Because the solid phase has greater inertia than the gas phase. The relative speed between the two phases is relatively large. This will help to enhance the mass transfer and heat transfer, and then achieve a high production strength.
Step 5: Separation and Collection
After the wet materials are totally dry, the dry particles and hot air will be separated by the process receiver or baghouse dust collector. The separated dry particles will be delivered to the storage tank and discharged through the rotary airlock.
Step 6: Exhaust Gas
The final step is to treat the exhaust gas. There is a large amount of water and particles in the exhaust gas. It is necessary to remove particulate matter before emission. On the one hand, removing particulate matter from exhaust gas is necessary according to environmental regulations. On the other hand, it is also possible to recover some useful particulate matter mixed in with the gas flow.

Advantages of the Flash Dryer
High-efficiency Drying
The flash dryer has a high-efficiency drying ability because of the combination of the hot air and the mixer. It can quickly evaporate the water in your wet material. Then shorten the residence time of the powder in the drying chamber. One drying cycle is within seconds. In addition, there is a cooling device at the bottom of the hot wind entrance, which can help prevent your heat-sensitive products from deterioration in the high-temperature zone at the bottom.
Controllable
The flash dryer is totally controllable. The drying chamber has the graded rings and swirl vanes, which can help to control the air volume, temperature and humidity during the drying period. Different drying parameters can adjust the fineness and moisture content of your materials. The moisture in the calcium carbonate can be adjusted to less than 0.1%.
Multifunctional
Whatever the powder, particles, slurry, or paste, the flash dryer has high versatility to dry different forms of materials from different industries. If your drying business needs to dry various materials in one production cycle, then the flash dryer is your best choice.
Automation
The flash dryer can be equipped with the PLC control system and online moisture content testing mold to achieve automatic temperature control, feeding and discharge. Fully automatic flash dryers can minimize manual operation. If you want to dry minerals, automatic operation devices can greatly improve the efficiency of mineral processing.
Safe
The flash dryer has a safety system to ensure total safety during the drying process. The flash dryer has standardized fire safety technology, an explosion-proof pressure relief valve, and an automatic carbon dioxide monitor to strictly ensure the operator’s personal safety. You can also equip an enhanced system in the flash dryer to prevent the dust explosion.
If you need to dry the hazardous feed materials that will produce non-aqueous solvent residues, it’s better to install an extra closed-loop hydrocyclone system. This will dry the material in the inert gases and improve the purity of your materials, such as chemical intermediates, pharmaceutical raw materials.
Types of Flash Dryers
Flash dryers can be divided into three types according to different hot air flow methods: the heated rotary flash dryer and the fluid bed flash dryer.
Rotary Flash Dryer
The heated rotary flash dryer is the most commonly used type of flash dryer now. It is a combined internal helical blade with an inclined rotating cylinder. The heated rotary flash dryer can directly contact the wet material with the drying medium, and then form two flowing methods: parallel and countercurrent. It is widely used to dry the material with low density, such as straw and leaves, or fine powders, granular materials, and pellets.
Fluid Bed Flash Dryer
The fluid bed flash dryer is a similar operation process to the heated rotary flash dryer. It can deliver the wet power, particles or flaky material to a multi-hole bed equipment. Then adjust the hot air flow speed to keep the material layer in a fluidized state. This method forces hot air through the material and dries it. So it has a strong advantage in drying the material with high-density, like wood chips or sawdust.

No. For heat-resistant chemical products, flash dryers offer energy efficiencies of up to 70–85%. This is because the material spends a short time inside the drying chamber, reducing energy loss. If you want even higher efficiency, you can configure heat pump technology and waste heat recovery systems. This not only improves energy efficiency but also increases recycling rates.
Flash dryers are made of over 90% stainless steel, making them easy to clean. You can also achieve automatic cleaning by installing an automatic in-situ cleaning system. The automatic cleaning systems can shorten cleaning time while reducing the use of water and chemicals. This not only reduces wastewater discharge, but also saves your costs on wastewater treatment.
