The rotary drum dryers are a crucial step in the production line of the pellets. They are used to remove moisture from the raw material and increase the product quality. Apart from pellet production, rotary drum dryers have a lot of different industrial applications where they serve the purpose of drying.
Understanding the rotary drum dryer
The rotary drum dryers are specialized machines that are used for moisture removal. They are used on different commodities for this moisture removal function in pellet production; they remove the moisture from the raw material.
Their core function is moisture removal, and it is done by the cylindrical design of the drum. The drum has a heating facility, and by the use of this heat, the drying is done. The basic principle of drying is through the convecting heating in the rotary drum dryer.
The cylindrical drum rotates, and the wet material that is present in the drum is lifted into the hot air, and then it comes back. By this lifting and falling process, moisture is removed from the material. Due to the cylindrical design, the drying process efficiency is increased as constant and uniform heat is distracted, and it contacts almost all the material.
The pace of the drying system in the rotational drum dryer is constrained by the temperature and the speed of the air, as they are vital elements in the drying.
Rotary drum dryers can be utilized for various materials like minerals, pellet agriculture, and some more, so it is a seriously helpful thing in the general sense.
Industrial applications of the rotary drum dryer
Talking about the industrial application of the rotary drum dryer, we have compiled a list of industries.
- There is a great demand for the rotary drum dryer in pellet formation. In forming the wood and biomass pellet production, you must remove the raw material’s moisture. If not removed, this moisture hinders the production. At this time, the rotary drum dryer removes the moisture so that we have the best quality pellet.
- The rotary drum dryer has a profound use in the agriculture industry. Its use is for drying grains like rice, corn, and other products. These agricultural products are dried, and then they are more easily transported and stored. With the drying, the moisture level of the grains is reduced and then can last for a long time, increasing their shelf life.
- In the food industry, drying has a major role. The basics of the food industry stand on the shelf life of the products, and the food industry strives to make more and more methods that can help them increase the shelf life of the products. Moisture is the main culprit for the deterioration and the lesser shelf life of the food; hence, pieces of equipment are needed for its removal, and a rotary drum dryer performs that function.
More Information
- In the mining industry, the rotary drum dryer has many applications. Like the agriculture products, the mined products also need drying. The minerals ores and concentrates need drying after extraction to reduce their moisture content. This moisture reduction is essential for further processing these mining products.
- The rotary drum dryers also have a profound usage in the chemical industry. In the chemical industry, there is a need to dry the various chemical compounds; drying these chemical compounds results in the formation of various necessary catalysts and chemical intermediates. So, for the formation of these compounds, the dryer is used.
- Pharmaceutical drying has a major application of rotary drum dryers. The various medicines are to be present in granule or powdered form with a very low moisture percentage. To achieve that moisture percentage, you need drying, where the rotary drum dryer comes to the rescue.
- The last in our application list, the textile and paper & pulp industry also uses the rotary drum dryer. In the textile, the rotary drum dryer is used to dry the dyed fabric and the textiles, and in the paper and pulp, paper pulp is dried through the rotary drum dryer.
Benefits of rotary drum dryers
Talking about the benefits of using rotary drum dryers, we have made a list of their benefits.
Efficient moisture removal
The main benefit most often linked with the rotary drum dryer is its ability to remove almost all the moisture. It efficiently removes the moisture from the material, and that speeds up the process of moisture removal. The hot air currents help in the efficient moisture removal; thus, we get a moisture-free outcome.
Uniform drying
Another benefit that we get from the use of a rotary drum dryer is the uniformity in the drying.in most of the drying methods, we get this issue that the product was not properly dried or better dried on some portions but not properly from the other ones. This is due to the cylindrical design of the rotary drum dryer that gets uniform heat transfer so the product is uniformly dried.
Can handle and manage various products
The industries try to manage their cost by reducing the cost of the varied machinery for the same drying cause. In order to have a one-in-all solution, we have the rotary drum dryer. The rotary drum dryers can handle various types of materials, from wood biomass to minerals and agricultural products. So, it sort of becomes a one-stop thing when it comes to drying a variety of materials.
Cost-effective
The rotary drum dryer also reduces the cost of drying the commodities. The higher efficiency of the rotary drum dryer assists in reducing the drying time. As the drying time of the commodities is reduced, there is a decrease in the energy cost, thus making the process overall cost-effective.
Better quality outcome
The one last benefit in our list is the better quality product. The materials that are dried through the rotary drum dryer often exhibit high-quality outcomes with a longer shelf life and quality.
