The Evaporation Process

Caloris is a world-leader in delivering process solutions in evaporation technology for existing or new equipment installations. Whether you are in the food, dairy, or beverage industry (including juice), or have an industrial or wastewater process that involves evaporation, the Caloris team brings to bear hundreds of years of experience to evaluate and design innovative solutions to meet your needs.

How Does the Evaporation Process Work?

The process of evaporation involves the removal of water (or other solvents) from a product or wastewater stream by adding energy to change the physical state from a liquid to a gas. In an efficient system, this energy is then recaptured as the gas (or vapor) state is condensed back to the liquid state.

With a keen eye towards the customer’s needs, the Caloris team focuses on delivering projects that focus on:

  • Process Capacity Optimization
  • Energy Optimization
  • Robust Operation

Evaporation FAQs

What does MVR stand for?

MVR stands for Mechanical Vapor Recompression. MVR turbofans generate heating vapors by compression of the water vapors evaporated from the product. For more information, see our blog.

How do I know what type of evaporator will work for my situation?

Caloris will work closely with you to learn about your current system and processing goals. We will bring our pilot equipment to your location for on-site testing, when applicable. The information derived from this testing will help us tailor your evaporation system to your exact needs.

Doesn't evaporation require a lot of energy?

Evaporation can be a very energy-intensive process, but Caloris specializes in the design and optimization of evaporators for peak energy-efficiency. Our patented designs ensure that your Caloris evaporator wastes no energy. Learn more about advances in evaporator energy efficiency on our blog.

Does Caloris only service Caloris evaporators?

Caloris can assess, modify, repair and optimize evaporation equipment from almost any manufacturer, including companies who are no longer in operation. Send us an email at or give us a call at 410-822-6900 if you need assistance with your existing evaporator.

Evaporation Process

All of us benefit from the evaporation process every day, in the beverages we drink, the foods we eat, and the products we use.

Evaporation Process for Foods & Beverages

Thermal processing can be used to evaporate liquid from many products. Beverage producers use evaporation processing to create concentrates (such as juice concentrates). Dairy producers use it to concentrate skim milk, whole milk, whey or lactose, which can then be sold as concentrated liquids or dried for use in new products like infant formula or protein shakes.

Evaporation Process for Industrial Wastewater

Many industrial processes use huge volumes of water. For instance, metal cans must be rinsed with water after they are manufactured. Simply flushing the untreated wastewater from this process down the drain would be wasteful and potentially harmful to the environment. In the past, processing plants have had to truck the wastewater to a treatment plant. But this can be very expensive and inefficient. Using evaporation, however, manufacturers can create clean water (condensed steam) from the wastewater on site. This clean water can then be reused in the processing plant. This helps processing plants save money—they no longer have to truck large volumes of wastewater to a treatment facility; they can recycle the clean water within the plant—while helping to protect our environment.

Evaporation Process for the Ethanol Industry

Ethanol producers are left with a syrupy liquid after they extract the biofuel from a food by-product (corn syrup, for example). Thermal process technology can be used to evaporate water from the syrup enabling the concentrated syrup to be used as animal feed.
