Common Dryers Used for Powder
Based on different types of powder materials, you can choose different dryers to meet the actual demands. Learning their features and advantages may help you make a better purchase decision. The following are common dryers used for powder:
Spray Dryer
Working Principle
The spray dryer is the most common type used to produce powder. It features an atomizer to atomize liquids into fine droplets. Then it spray the droplets into the drying chamber to dry them through hot air. The spray dryer offers high drying speed to evaporate water content of the droplets, generating uniform powers with good flowability.
Advantages
- High Efficiency: The drying process of a spray dryer used for powder can be controlled within the range of 5- 15 seconds. The machine also features high drying capacity within a range of 50L/h to 5,000L/h. The spray dryer achieves continuous operation to handle a large amount of liquid materials, making it suitable for large-scale projects.
- Excellent Product Quality: Powders produced by the spray dryer typically feature excellent flowability, dispersibility, and solubility. By adjusting the atomizer types, drying temperature, and other key parameters, you can control particle sizes, density, and bulk density of the finished products.
- High Compatibility: The spray dryer is flexible to handle different types of materials such as solutions, emulsions, suspensions, and slurries. It is widely used in various industries. In addition, due to its extremely high drying speed, the spray dryer is also suitable for heat-sensitive materials to preserve active components.
Limitations
The spray dryer also has some limitations. Its structure is relatively big to consume more energy, which may increase your costs. For materials that are extremely sensitive to heat, the spray dryer is not suitable. It also has strict demands on the viscosity of raw materials to prevent sticking issues.
Drum Scraper Dryer
Working Principle
A drum scraper dryer is a type of contact drying device, which features one or two rotary drums. Raw material can be sprayed or coated on the drum and rotate following the drum. The rotary drum of a drum scraper dryer is heated evenly by steam, thermal oil, or hot water, to evaporate the water content. The drum scraper dryer is also equipped with a scraper to remove dried flake materials, which can be pulverized into powders.
Advantages
- High Thermal Efficiency: The drum scraper dryer offers high thermal efficiency that can reach 70%- 80% due to its short heat transfer path. Thereby making its energy consumption lower than a spray dryer when evaporating the same water contents.
- High Drying Capacity: For slurries, pastes, and other high-viscosity materials, the drum scraper dryer offers high capacity to handle them. These materials will form thin layers on the drum surface to accelerate drying time while also preventing clogging issues. You can also adjust the rotation speed and temperature of the drum to control product porosity and dissolution rate.
- Low Footprint: The structure of drum scraper dryers is simple, making it easy to maintain. It also achieves a compact footprint to enhance the production capacity per unit area.
Limitations
The drying area of a drum scraper dryer is limited by the drum surface area, which means you may need multiple machines to complete large projects. The drum scraper dryer is also not suitable to handle too thin fluids or extremely heat-sensitive materials. In addition, final products of the drum scraper dryer are flake or scale-like. You need to purchase another machine or add an additional grinding process to produce powders.
Fluid Bed Dryer
Working Principle
The fluid bed dryer is one of the most widely used methods in the industry, and is suitable for granular, powdered, and flaked materials. In short, the hot air flows through the material bed, suspending particles to achieve a uniform heating and drying process. Particles are lifted by the air flow, achieving a complete mix.
Advantages
- High Efficiency: The fluid bed dryer offers fluidization to the materials, ensuring complete contact between materials and hot air flows. This not only improves the drying efficiency, but also enhances the thermal utilization of the dryer.
- Uniform Drying: Raw materials are mixed within the bed intensely, which significantly prevents localized overheating or uneven drying failures. The uniform drying process improves consistency of finished products to ensure high quality. Its temperature can be also controlled based on actual demands to handle heat-sensitive particles.
- Flexible Process: This type of fluid dryer supports continuous operation and offers multiple functions within the single machine. It achieves integrated drying and cooling to build a highly automated production line. You can control the airflow, temperature, and time of the fluid bed dryer to precisely adjust the drying process.
Limitations
The fluid bed dryer has strict demands on the particle sizes, material viscosity, and humidity content. The physical properties of raw materials are key limitations when using a fluid bed dryer. In addition, the intense fluidization process requires a large amount of energy and may cause collision wear between particles.
Spin Flash Dryer
Core Advantages
- Rapid Drying Process: The spin flash dryer offers a combined state of fluid bed and airflow drying. Raw materials are instantly dispersed into fine particles to mix with hot air（up to 400 °C) completely. The dryer achieves extremely high heat transfer efficiency to accelerate the drying time.
- High Capacity: The biggest advantage of the spin flash dryer is that it supports handling paste-like and filter cake materials without pre-crushing and pre-granulation steps. It achieves a wide range of particle sizes within 10μm to 2mm. This significantly shortens the drying process thereby saving energy consumption and improving drying efficiency.
- Prevent Clogging: This machine prevents sticking and clogging issues by its continuous rotation of the bottom agitator. In addition, the materials in the drying chamber are in suspension to rotate following hot air, which prevents localized overheating.
Applications
Due to its unique advantages, the spin flash dryer is widely used in the chemical industry, including pigments, dyes, inorganic salts, and catalyst filter cake. It can be also used to handle various metal hydroxide or industrial sludges, meeting the environmental protection demands. If you want to use the dryer in the food industry, you should ensure that it obtains certain certifications.
How to Select Suitable Fluid Dryer
