Tube evaporator

Variety of models: explore an extensive selection of tube evaporators from Foeth

Evaporators are useful for concentrating nonvolatile solutes and volatile solvents by changing states at different temperatures. The process uses heaters and condensers to produce a concentrated solution, viscous liquid or slurry. You can use tube evaporatorsin various industrial processes, from pulp and paper manufacture to food processing and pharmaceutical products. If you are shopping around for budget-friendly industrial equipment, Foeth has got you covered with high-quality used and refurbished machinery. You can get them at a pocket-friendly price, making them a worthwhile investment since they are efficient and improve your product quality. You can choose from multiple brands of film evaporators and select the suitable equipment for your needs.

Get high-quality used tube evaporators for your industrial applications.

What are the uses of a horizontal tube evaporator?

A tube evaporator is a machine used to separate two or more substances with different boiling points. The process relies on changes in state at different temperatures and uses heaters and condensers to achieve the desired boiling points. The standard vertical tube evaporator has many industrial applications that require bulk separation of solvents after extraction. For instance, when you use a solvent to extract oil, you need to remove the solvent from the oil extract. Falling film evaporators use a heat source like heat pumps to heat the fluid mixture until the lower boiling point fluid becomes gaseous, leaving the mixture. A condenser is used to turn the separated gas into a liquid. In the falling film evaporator, the equipment is in an inverted position. You feed the evaporator from the top, and the gravitational pull forces the separated liquid downwards. The main applications of the process are the concentration of dairy products, black liquor, phosphoric acid and sugar solutions.

Types of long tube evaporators

Evaporators can be vacuum pans, which complete the separation in batches or continuous flow evaporators. For industrial applications, continuous flow tube evaporators promote efficiency and save time. Like falling and rising film evaporators, continuous flow evaporators are usually available in horizontal or vertical tubes, but they perform similar functions. For instance, the horizontal tube evaporator allows the materials to boil outside the horizontal tube, and you can collect the condensed liquid inside the tube. The liquid boils inside vertical tubes and rises upwards in vertical tube evaporators, while the other liquid condenses at the bottom. Short-tube vertical evaporators have short tubes and horizontal tube sheets that return the concentrate to the bottom for product withdrawal. These evaporators rely on the difference in densities of the liquids and the high heat-transfer coefficients.
