Multi-Effect Evaporator
In order to increase stability and also to improve efficiency in storage and transportation, it is desirable to concentrate Aloe. Final products that are currently marketed in the liquid form range from 5 times concentrated (5X) to 40X. However since Aloe is sensitive to heat, the concentration must be carried out at the lowest possible temperature. There are numerous designs of evaporators that work under high vacuum to facilitate water evaporation at low temperature. It is also important here to maximize heat transfer efficiency to lower the operational cost of the unit, therefore several evaporation chambers are placed in series and the hot evaporated gases from the first go to heat the second and so forth. This is called a multiple effect evaporator. The more the effects, the more efficient the operation. Typical operating temperature is about 140F (60C).
