Evaporation in food industry

Liquid circulation is rather poor in this type of evaporator. Vertical-tube Evaporators: By using vertical, rather than horizontal tubes, the natural circulation of the heated liquid can be made to give good heat transfer. The standard evaporator, shown in Figure 1, is an example of this type. Get price

Should I Replace My AC's Evaporator Coil or the Whole AC

The evaporator coil you need to replace is obsolete. Every AC has a "SEER" rating (ranging from 13 to 21) that determines how efficient the unit is. The higher the SEER, the more efficient the unit (and the coil). The federal minimum SEER rating is 14. But if you have an older unit, it could have a SEER rating that's a lot lower than that.

Types Of Condensers

Jan 30, 2013In the world of HVAC, condensers happen to be a topic of great importance. Instead of confusing information, my goal is to provide you with some basic information on the different types of condensers and their applications. There are 3 condensers used in HVAC systems Water-cooled Air-cooled Evaporative Applications Air cooled – If the condenser Get price

Wiped Film Evaporator –WFE

In essence, the Pfaudler Wiped Film Evaporator (WFE) is designed to continuously separate volatile compounds by introducing a mechani-cally agitated, thin film of feed material to a heated surface. The short residence time allows for efficient and reliable processing of a wide variety of high-boiling, heat-sensitive and/or viscous products. Get price

Fundamentals of Multiple Effect Evaporation

removed periodically. By using this type of arrangement, 1 kg of steam can evaporate, at most, 0.8 kg of vapor from 2 kg of the seawater supplied. The remaining 1.2 kg of brine has a higher salt concentration than the feed and should be removed (blowdown). The released 0.8 kg of vapor is condensed in the condenser by the use of cooling seawater. Get price

What Are Evaporators and What Are They For?

This type of evaporator, also called calandria or Robert, was the first one to be widely used in the industrial sector, and it's still the most common today. Inside a short tube evaporator, the bundle of tubes for the exchange of heat are enclosed in another steel cylinder (also called calandria), placed at the bottom part of the shell. Get price
