CORRECT|GRADE A+
Reactor - ANSWER Device that causes materials to undergo a controlled reaction.
Centrifuge - ANSWER Machine with rapidly rotating container used to separate materials by their
densities (usually liquids). Used as a separator basically.
Compressor - ANSWER A device that is used to compress gases for various applications. Can be used for
forcing gases to diffuse into a liquid (carbonation of soda)
Crystallizer - ANSWER A device that causes the solutes in a solution to form a solid, usually used for solid-
liquid separation.
Distillation Column - ANSWER Used to separate liquid mixtures by boiling one of the liquids so that it
condenses and evaporates again, causing the mixture to distill.
Dryer - ANSWER Extracts the water from a mixture by making the water evaporate, usually a final
production step.
Filtration Device - ANSWER Used to separate solids from a liquid. (Think of a coffee filter)
Heat Exchanger - ANSWER Transfers heat from one medium to another. In Industry, it can be used to
recover exhausted heat from the process, thus saving energy and money.
Holding Tank - ANSWER Large container where liquids are held.
Mixer - ANSWER Takes in materials and brings them together to form a homogeneous mixture.
