\VILHELM VEULETH, OF DARMSTADT, GERMANY.
VAPORATI NG APPARATUS.
SPECIFICATION forming part of Letters Patent No. 464,166, dated December 1, 1891.
Application tiled April 14, 1890. Serial No. 347,868. (No model.)
To a/ZZ 1072077@ it may con/cern.'
Be it known that I, WILHELM VENULETH, a subject of the Emperor ot Germany, residing at Darmstadt, Germany, have invented new and useful Improvements in Evaporating Apparatus for Semi-Liquid Substances, of which the following isa full, clear, and eX- act description.
In the annexed drawings, which form a part of this specification,Figure 1 represents a longitudinal section of the apparatus. Fig. 2 represents a cross-section of the same, and Fig. 3 represents on an enlarged scale-a crosssection of the hollow shaft and stirrers.
A hollow shaft B B rotates in a vessel A of suitable form-in this example of a troughlike shape-containing the mash which is to be evaporated. This hollow shaft is provided along its entire length within the vessel with hollow fan shaped stirrers C, arranged in pairs, as'represented in the drawings,in such manner that the two stirrers of each pair are opposite each other, so that both can be fastened to the shaft B B with a single screwbolt D. The steam used for heating purposes is introduced at B', passes through the hollow shaft and the hollow stirrers, and the Water of condensation isdischarged through the pipe F.
As shown in Fig. 3,'the stirrers are inserted in the shaft B B with their tenons projecting into the hollow thereof nearly to the center, so that the water of condensation collecting in the lower part of the shaft hollow cannot `iiow into the stirrers. In order to prevent the water of condensation formed in the upper stirrers from dropping into the opposite stirrers, I have arranged small movable plates or automatic valves G between the tenons of the stirrers and sliding on the screw rod or bolt D, which valves will automatically drop down on and close the opening or mouth of the lower stirrer.
The rotary motion of the shaft is obtained by means of pulleys or wheels H. At every revolution of the shaft the stirrers will empty the water of condensation therein into the yfaces no particle of the. mash can settle on the stirrers.
The whole apparatus is arranged slightly inclinin g toward B', in order to eect a quicker discharge of the water of condensation from the hollow shaft. 1
Having fully described my invention, what I claim as new, and desire to secure by Letl. An apparatus for evaporating, consisting, essentially, of a hollow shaft, fan-shaped pipes arranged in pairs and on opposite sides of said shaft, tenons on said pipes insertedin said shaft, screw-bolts connecting the pipes of each pair, passing through their hollow part and tenons, and Amovable valves carried by said screw-bolts between these tenons, substantially 'as and for the purpose specified.
2. In an evaporating apparatus, the combination, with the shaft and the hollow stirrers having tenons, of screw-bolts passing through and connecting said stirrers, and movable plates or Valves between the tenons of the stirrers and adapted to slide on said screw-bolts, substantially as and for the purpose specified.
In testimony whereof I have signed my name to this specication in the presence of two subscribing witnesses.
WILHELM VENULETH.
