Common Uses and Applications for Evaporators

As the name suggests, evaporators are devices that cause a material to evaporate, or enter its gaseous state. Because of their broad range of practical uses, they can be found in a variety of applications, ranging from agriculture to waste management. To illustrate the versatility of these essential devices, we’ll briefly walk you through some of their most common uses and applications below.

Common Uses for Evaporators

Evaporators are widely employed in most industries that depend on a constant supply of fluids or chemicals. HVAC systems, for example, use evaporator coils to vaporize compressed cooling chemicals, removing heat in the process. These systems also use condenser coils to exhaust the heat outside, making the entire process much more effective.

Heat recovery evaporators are used to convert seawater into clean water in desalination plants. Utility companies tend to prefer these evaporators over alternative solutions because of their simplicity and minimal energy requirements. The end result is lower operational costs.

Evaporators are also used in oil fields to separate water and various other compounds from crude oil. Though more difficult to use than other types of evaporators, these are nevertheless popular among energy companies because they can reduce operating costs while meeting government-mandated standards. Because they are relatively compact, they can also be easily transported to other locations.

The food industry employs evaporators to achieve product consistency. Coffee is a case in point. Evaporation is also used to concentrate liquid foods such as noodles and make condensed milk, the product of a process that removes water from milk. Similarly, pharmaceutical companies use evaporators to remove excess moisture from drugs, thus improving product stability.

Common Applications for Evaporators

Because of their efficiency, evaporators are well-suited to an array of industrial applications. They are particularly common in processing industries. Food and dairy products such as tomato purees, milk, herbal extracts, gelatin, coconut water, and whey and milk proteins are all processed with the help of evaporators. The same is true for chemicals such as dyes, ammonium nitrate, glycerin, sodium nitrate, paints, and pigments.

Evaporators are also ideal for very low temperature applications in the food and pharmaceutical industries. These include the production of plasma, fermented products, coffee extracts, fruit juices, bulk drugs, glycerin, sweet water, yeast extract, and protein hydrolysate. Whey, gelatin, malt extracts, glucose, fructose, dextrose, sorbitol, and maltodextrin are all produced with evaporators, as well.

Another field in which evaporators are widely used is waste management. Waste management providers rely on them to treat effluents, or wastewater, from various plants, including distilleries, grain mills, abattoirs, textile plants, chemical reactors, and storage tanks.

Designed to serve a variety of practical uses, evaporators are a versatile solution to many common industrial challenges. At Thermal Kinetics, we use our experience and expertise to manufacture evaporators that thrive in any application.

How to Choose the Best Evaporator for Your Application

pbk8-selection-guideA truly versatile device, evaporators are used in a wide range of industrial settings. Beverage manufacturers use evaporators to concentrate product and to optimize product consistency; pharmaceutical companies use them to eliminate potentially damaging moisture from medicines; and a number of industrial chemical sectors, such as the chloralkali industry, use them to concentrate chemical solutions.

Various types of evaporation equipment are available, to meet the needs of these diverse applications…

Factors to Consider During Evaporator Selection

To optimize performance, ensure product quality, and help reduce waste and operational costs, it’s important to select the right type of equipment for your unique application. Several factors should be kept in mind when choosing an evaporator.

First, consider the materials of construction of the evaporation system; materials can greatly impact system functionality, lifespan, and maintenance requirements.

Since evaporation generally takes place at elevated temperatures in the presence of corrosive chemicals, your evaporation equipment should be manufactured from a durable, strong material that can withstand severe process environments.

On the other hand, in industries where strict hygiene must be maintained, such as the food, beverage, and pharmaceutical sectors, it’s more important to select materials that are easy-to-clean and that can withstand the rigors of the chemicals used to Clean-in-Place (CIP) the process wetted surfaces.

Second, various operational characteristics should also be taken into consideration. For example, if the product you are evaporating is heat sensitive, a low-pressure or short time duration-evaporator will be ideal. A product’s propensity for fouling, fluctuating solid concentrations, reactivity, and viscosity should all be carefully considered. If you’re using the wrong evaporator, these properties can lead to process shutdowns, increased downtime for cleaning, and higher maintenance costs.

Thermal Kinetics manufactures a variety of evaporator systems, each of which is suitable for different applications. Our diverse product line includes Falling Film Tubular Evaporators, Rising Film Tubular or Plate Evaporators, Rising/Falling Film Tubular Evaporators, Forced Circulation Evaporators, Submerged Circulating Crystallizers, and specialized caustic concentration systems.
