What Is Infrared Radiation?

The sun sends IR radiation to the earth, similar to an IR emitter which sends radiation to the product, without any contact or transfer medium. 

Unlike the the sun, an IR emitter can be switched on and off whenever it is needed.

What are the benefits of Infrared heating?

Infrared radiation requires neither contact nor intermediate transfer medium.

Infrared emitters are precisely matched to the materials to be heated.

Fast response times allow controllable heat.

Heat is applied precisely where and only for so long as it is required.

What about IR wavelength?

The wavelength of an infrared emitter has a major influence on the efficiency of a thermal process. 

The better the emitted wavelength fits the absorption spectrum of the material to be heated, the more efficient the process.

For instance, water absorbs best at about 3000 nm. 

Therefore, medium-wave and carbon infrared (CIR) emitters are optimal to heat water and water-based coatings. 

The main emission of these emitters lies exactly within the range of the main absorption of water.

Another important emitter parameter is power, measured in W/cm (emitter length) or kW/m2 (power density). 

Due to the higher temperatures of the heating filaments, the power density of short-wave or halogen emitters is in most cases higher than that of medium-wave infrared emitters.

When selecting an infrared emitter for an industrial process, wavelength and power are among the most important parameters that are taken into account.

Where can infrared heating be used?

Infrared can be used in the majority of industrial heating processes.

(Hi) Worker Benefits of Maintaining Exhaust Fan: Food Industry Case Study.

Hi Case Study:

Application Overview:

A Snack Food Facility in needed to clean vegetable oil residues from its production line exhaust fan systems. The fans were so encrusted that they were out of balance and not adequately drawing the cooking oil vapors off the production line. With an average build-up of six inches of oil, the fan systems also were vibrating severely.

There are three fan systems, each approximately 350 square feet. Each system is comprised of a 6-foot diameter fan and motor in a fully enclosed shroud with hinged outflow louvers designed to open when the exhaust system is functional. However, the louvers were inoperable and propped up with broom handles.

Substrates:

Galvanized steel

Previous Methods:

A chemical solution was sprayed on all surfaces to soften the oils. This was followed with hand scraping and a hot water rinse. Unfortunately, the chemical solution eventually was unable to remove the continued build-up.

Special Concerns:

First, the cleaning materials needed to be approved for use in a food production facility. Second, the fan system needed to be protected from damage. Third, dust had to be minimized to avoid migration throughout the plant.

Project Schedule:

Each fan system had to be cleaned between 5:00 a.m. and 5:00 p.m. on the one scheduled "down day" per week. Cleaning the rooftop mounted exhaust fans in temperature averaging 100 degrees posed a special challenge to the workers.

Containment:

Dust suppression was the only containment required. All material was flushed down the inside of the ventilation chamber to the production room floor below for clean up by the facility sanitation personnel.

Results/Benefits Summary:

The production personnel reaped immediate and measurable benefits. After cleaning, the fans and exhaust systems functioned as designed. The hinged shrouds opened easily, and fans operated with zero vibration. Production personnel reported that there was a "world of difference" on the production floor due to proper exhaust operation. As a result, the maintenance personnel are establishing an ongoing cleaning schedule.
