"fakaum - circulation evaporator for

The 3rfinaotxg concerns a V aituua — circulation via steam or for laboratory & toriame purposes. In the modern laboratory it is necessary to use a circulation evaporator to steam the lin & steam in the falruoni voraaneiimen ₉ where boho oxide and raaeii have to be worked wad often a larger, narrow, dilute solution has to be evaporated without special maintenance. In the laboratory, the demand is made on the evaporator that it allows the evaporation of larger amounts of liquid without maintenance and that it also allows small amounts of waste to be produced. The apparatus was used to carry out these tasks in the laboratory. Pesson apparatus is bulky and, due to its glass construction, easily breakable. Because Vt-steam flask and the rest

Apparatus Generally not thermally insulated, the power of this device is limited. very take the steam and condensation ailments as an unpleasant g-eräasch in jßrecheinang. Be? I the serbreehliehen The construction of the apparatus, the aacn pose a considerable risk to the entire system.

Sorch. The Haehteile of the known apparatuses are removed, inäem invention a vertical evaporator vessel for the user whose circumference is blown out of length folds, which are surrounded by the heating medium and on the other hand, on the inside, the liquid to be thickened rises up , w & over an inner * inserted hollow body to flow downwards again.

The slits, seen in section, form an endless serpentine line that represents the mantle of the vessel 5. The longitudinal folds 6 are flushed out on the left side by the steam developed in the container 1, while the liquid to be thickened rises on the inside of the container with the longitudinal folds 6. A hollow cylinder 7 is inserted into the interior of the fold part ©, which rests against the longitudinal folds and over which the S ¹ which is to be thickened can flow backwards.

On the upper part of the vessel 5 there is placed an outer cone & enestor which is formed from a pipe 11, which is arranged in a spiral-like manner and is preferably flat in cross-section, through which the cooling liquid flows.
