Ferrite Microwave Technologies complete microwave drying systems offer rapid water removal solutions for several industrial processes. Microwave drying is quicker, and frequently more energy efficient than traditional methods like drying rooms and convection ovens. Depending on the material you’re drying and the processing requirements, the systems energy requirements will vary. Fortunately, the team at FMT has decades of experience developing microwave drying systems for a wide range of industrial processing applications. We’ve manufactured systems for products ranging from loose sheet materials, to agricultural grain products, to wood and lumber, all the way to drying systems for treatment of biomass.
Drying Systems
If your main focus is evaporating water from your products, microwave drying systems are an ideal solution. Whether you are drying out building materials, frozen foods, or fabrics – energy requirements vary widely depending upon the specific material and application. Microwave drying your products with complete systems is faster and often more efficient in terms of energy, than traditional methods like drying rooms and convection ovens.
Foam Drying
Foam is one of the natural candidates for microwave treatment. The manufacturing process involves extensive drying and the homogenous consistency, and microwave transparency, makes drying with microwaves very efficient. Our systems minimize the risk of over-drying or marring the surface of the product, and allow the microwave energy to be increasingly absorbed in areas of high moisture content. Depending on the product material and its desired final results, we offer specialized systems for microwave drying of high moisture content products.
Oil & Coal Drying
Microwave coal drying can be more cost effective for certain clients in energy markets where electricity is relatively cheap. For oil treatment, you can crack an oil molecule with microwave. In doing so, you can avoid the necessity of using a cracking tower. Microwave systems offer both of these marketplaces production flexibility, and a decreased facility footprint. We’ve modularized systems for both oil and coal applications, making it easier to move production to another location at lower costs than incurred for traditional oil, coal, or other energy treatment equipment.
Textiles & Fabrics
Textiles and fabrics applications benefit from the excellent color drying and adhesive setting properties of microwave power. Also, as a process that involves drying as well, microwave treatment has an added benefit. Whether the material is non-woven fabric, carpet, textiles, or a product of similar thickness, we offer microwave drying systems that ensure microwave energy is uniformly distributed so that the target material achieves desired results. Our solutions are flexible, modular and versatile – offering users the ability to heat, pre-heat, post-dry or stand-alone dry.
Microwave Drying: MIP9
Ferrite Microwave Technologies MIP9 drying system offers end users increased yield, throughput, and energy efficiency. It also allows its users flexibility through instantaneous controls. This unit offers boost drying capabilities for food applications, as well as drying capabilities for non-food applications. FMT customers utilize microwave drying systems to evaporate water from items like: snack foods, spices, biomass, foam, and coal.
How Do Microwave Drying Systems Work?
A drying unit is made up of three parts: (1) the generator, (2) the waveguide, and (3) the applicator. The applicator for microwave systems is most often a multi-mode cavity. Inside, microwaves bounce around, drying the material that passes through from all directions. The standing wave pattern in the cavity oscillates the water molecules at the frequency of the generator.
Planar Drying
Planar drying with microwave systems continuously heats and or dries a thin sheet or bed of product. Often, it is horizontally conveyed through a rectangular drying chamber or applicator on a specially selected microwave inert plastic modular belt. When combined with other thermal technologies, PHS can optimize final heater retrofits or new production lines. Optimum payback is usually obtained by utilizing a planar heater in a process application, either as a pre-heater or as a post heater, in combination with a traditional gas-fired re-circulating hot air dryer.
High Moisture Drying
High moisture microwave drying systems are available for the textile, pet food, non-woven materials, foam, coal, biomass, and agricultural processing industries. They are recommended as single or multiple units connected in parallel, series, or a combination of both. In some cases, it is possible to split the power from a single 100 kW generator into several input ports located along or across the applicators. This allows the conveyed material exposure to a lower power density which can improve the overall quality of a variety of heat sensitive, granular or sheet products.
Liquids Heating
Ferrite Microwave Technologies specializes in rapid, continuous processing of high-value, heat and shear sensitive pumpable fluids. For thermal processing of chemical formulations, liquids, or fluids, we have the ability to test your product on a small-scale bench top microwave processing system similar to the 6 kW unit shown above. This system can use either a 1/2″ or 3/4″ ID product heating tube to minimize the hold up volume and amount of test fluid required. We’ve applied microwave technology to various chemical and industrial formulations.
RWG Microwave Drying Systems
Our patented RWG (Ridged Waveguide) Applicator eliminates hot spots by uniformly drying thin materials of medium to low-moisture content. Typically, this system is for products that do not efficiently absorb energy by conventional conductive or convective heat transfer processes. Products successfully heated or dried in this system include: corrugated paper, crumb rubber, insulation materials, medical foam, non-woven materials, textiles, wood products, and more.
