Evaporators - Dairy Processing Handbook
网页Nowadays, falling-film tubular evaporators are mainly used for high capacity concentration in the dairy industry. The complete calandria heating unit is made of stainless steel and divided into a number of sections separate from each other. Depending on the nature of the process, the calandria is divided into 4 – 6 sections in a pre-concentrator.

网页The basic module of an evaporator is known as the “body” of the evaporator and refers to the calandria and the flash chamber. The term “effect” is used to describe the body where vapor is extracted from the raw material and is operating at the same boiling point.
Selecting Evaporators For Process Applications - LCI Corp
网页The short-tube, or calandria, vertical evaporator (Figure 3) is one of the earliest types still in widespread commercial use (3). The short-tube evaporator is characterized by tubesheets (A)extending across the body and a central downspout (B).
What is Short Tube Vertical Evaporator? Working Principle, …
网页Short tube vertical evaporator is also known as calandria type evaporator and crystallizing evaporator. In short tube vertical evaporator, liquid feed is passed through a set of vertical tubes.
网页Evaporation is an operation used to remove a liquid from a solution, suspension, or emulsion by boiling off some of the liquid. It is thus a thermal separation, or thermal concentration, process. We define the evaporation process as one that starts with a liquid product and ends up with a more concentrated, but still liquid and still pumpable ...
网页EVAPORATORS. TYPES AND DESIGN. In the evaporation process, concentration of a product is accomplished by boiling out a solvent, generally water. The recovered end product should have an optimum solids content consistent with desired product quality and operating economics.
