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.
