Evaporators | Dairy Processing Handbook

The theory is that if two evaporators are connected in series, the second effect can operate at a higher vacuum (and therefore at a lower temperature) than the first. The vapour evolved from the product in the first effect can be used as the heating medium for the next effect, which operates at a lower boiling temperature due to the higher vacuum.

3. Wait for the vacuum to reach 100 to 150 mtorr. This value is read of the chamber TC gauge (see Figures 1 and 2). If this vacuum is not achieved within 5 minutes, there might be a leak in the chamber. Please contact the NRF staff. 4. Power the turbo pump by turning the switch on the top panel and then the start button on the turbo controller.

White Paper: Evaporator Issues and Technology

RF evaporators use vertical tubes where the liquor is introduced at the bottom, the tubes are steam heated on the outside to the liquor boiling point, and partial evaporation occurs in the tubes. In the FF evaporator, the liquor enters at the top and is distributed on a vertical heat exchange surface composed of plates or tubes.

Rotary Evaporation to Remove Solvent | Protocol

Rotary evaporation is a technique commonly used in organic chemistry to remove a volatile solvent from a non-volatile compound of interest. Invented by Lyman C. Craig in 1950 the rotary evaporator, or rotovap, gently removes solvents from compounds using heat combined with reduced pressure to evaporate, dry, and purify samples for further downstream use.

A steam hood will only create a draft upward pulling the expanding steam from the evaporator. Like a fire place a good draft only pulls the smoke up the chimney it does not create a vacuum on the wood. Most hoods have alot of leaks around them so they really dont create a vacuum directly to the cooking sap.
