The film evaporators are designed for thickening of syrup by ___________of water. The evaporator is ______in the sugar-produc­ing industry making part of multiple-effect stations as tail-end units (4th, 5th, etc.)

The evaporator is a welded vertical cylin­drical steel vessel composed of three main parts: heating chamber,juice _________and distribution unit.

Heating chamberconsists of a cowling, upper and lower tube plates with heating tubes expanded into them. Vapor, through branch pipesis _________to steam jacket and then via the split-like holes directly to the steam chamber. To ________vibration of the heating tubes the heating chamber is provided with welded tube plates inside it. The heating chamber has four access ports. Non-condensed gases are __________through ammonia withdrawals. In the lower part of the heating chamber above the lower tube plate two branch pipes are arranged for removal of condensate.

Immediately under the ________chamber there is juice chamber. This chamber is ________of support with conical bottomin the center of which there is a pipe branchfor the removal of syrup to the next stage of the evaporation station. At the support part there are two _________and conical cowlings. In the bottom part of the chamber there are two pipesfor feeding syrup from the preced­ing unit andfor the removal of syrup for circulation to the upper part of the__________. Conical cowlinghas two pipe branches for removal of reheat steam from the_________. For separation of steam from the steam-and-syrup ________inside the juice chamber there is welded guide cone.
