Spiral Drying Machines
Spiral drying machines are an essential component for many different industrials drying processes. A spiral dryer is a device consisting of an elongated and vertically oriented chamber in which a product is placed between an opening at the top of the chamber. Inside the chamber, a helical blade sweeps in a spiral fashion, turning the product between each revolution of the blade to ensure even drying. This type of drying machine is often preferable to other drying equipment such as belt dryers or conical drum dryers due to its even distribution of heat, thereby ensuring that the product avoids hotspots while drying.
In the food production industry, spiral drying machines are commonly used to dry fruit, vegetables, and grains. The product is usually loaded into the top of the machine in large bi-conical shapes, and the spiral blade operates within the chamber to tumble the product towards the heated outlet. This motion ensures that the product is evenly dried, guaranteeing that the products retain the taste and appearance that is desired.
Another application of spiral drying machines is within the pharmaceutical industry. Many current pharmaceutical products are of a sterile nature, and require an even form of drying to ensure that the drugs retain their integrity during processing. The spiral blade inside the chamber is kept extremely clean, with many modern machines burning the air inside in order to sterilize it before and after operation. The product is then moved gently out of the chamber and onto another conveyor for further processing, ensuring that the sterile integrity of the drugs is maintained.
The third popular use of spiral drying machines is in the plastics industry. It is especially useful in the recycling process in which plastic waste is melted and filtered within the chamber while the spiral blade moves it towards the cooled exit. As the product moves along within the chamber, the heat is evenly spread, ensuring that the plastic cools off evenly, guaranteeing that the pieces keep their shape during the recycling process.
Spiral drying machines are an essential component for various industrial processes, as they offer a evenly distributed and extremely efficient method of drying. Whether used for drying food products, pharmaceuticals, or for recycling plastics, the spiral drying machine is a key tool for any industry which needs reliable drying methods. As the machines become ever more efficient, their popularity continues to rise in all of the industries mentioned above, making them increasingly essential for the production of everyday products.
