Controlling the moisture levels in the solid materials in the various industries is a prime factor. During the various manufacturing and production stages, all types of industries require specially built and customized industrial drying solutions. Any type of industry that is engaged in the production and manufacturing of solid powdered granular substance will require an effective drying technology based on the outcomes. Here we will mention some of the effective industrial drying solutions.
The mechanism for drying used in the industries.
As we all know the basic definition of drying is to dry out the moisture, water, or any other fluid substance for that matter. It can be done through heat transfer which is done in a variety of ways depending on the type of industry, the product being handled, and the outcomes it wants to achieve. Drying can also be accompanied by some physiochemical transformations within the product as desired by the industry.
Some of the most common types of drying are convection, which is direct heat transfer, indirect or through contact heating known as conduction, radiation known as radiant heating, dielectric heating, or microwave heating known as radiofrequency drying. Some industries also use infrared drying as a technique for industrial drying. Here are some of the drying solutions used in the industries:
It is a low-temperature drying solution for thermolabile materials. It involves the use of drying out solvents from a drying bed. The passing of heat is done using hot water through hollow shelves. The temperatures are tightly controlled and for most of the drying, the solid material is almost kept at the boiling point of the wet or fluid substance.
Fluidized bed dryers
It may pretty much look like boiling liquid, but the process is one of the most complex types of industrial drying. A preheated jetty of air is passed through the bottom of the container holding the substance to be dried. This sort of fluidizes the solid substance forming bubbles. The resultant mixture is solids and gas that behave like it was a liquid. The solid particles are that are to be separated fall into eddies and each fluidized particle is surrounded by the hot air gas which for highly efficient drying.
Freeze drying process.
This is an ultralow temperature drying process that is used in the complex drying processes within medical laboratories and nuclear research centers. The solvent is frozen the drying usually takes place through the sublimation of the solid substance. It is generally used in two types of situations. First when a high rate of decomposition occurs in normal drying and second, with substances that can be dried at high temperatures.
Microwave drying process.
A microwave drying process is a form of industrial drying where radio waves with high frequencies are passed through the substance to be dried. It has a range of laboratory and industrial solutions. The heating helps the solvent to become vaporized. The temperature of the solvent substance is kept above room temperature by the microwave heat input. Microwave drying is an efficient drying method with 50% lower turnaround time, than the vacuum drying process.
Spray drying is one of the efficient and highly scientific processes that involves some stages. This includes the atomization part mixing the fluid droplets with the particles, drying, and then collecting of the dried particles.
These processes are just some of the most used industrial drying processes. What type of drying process is used by the industry will depend on the type of drying outcomes to be achieved along with the drying efficiency and the type of material to be dried.
