MACHINE FOR THICKENING LIQUIDS.
SPECIFICATION forming part of Letters Patent No. 603,086, dated April 26, 1898. Application filed May 4, 1397. Serial No. 635,099. (No model.)
To all whom it may concern:
Be it known that we, OMAR T. JOSLIN, of New York, New York county, New York, and HERMAN B. SCHMIDT, of Cincinnati, Hamilton county, Ohio, have invented certain new and useful Improvements in Machines for Thickening Liquids, (Case D,) of which the following is a specification.
This invention pertains to improvements in machines for thickening liquids by process of transferring heat, as by vaporizing portions of the liquid away by adding heat or by cooling a warm liquid by abstracting heat from it.
Our present improvement will be readily understood from the following description, taken in connection with the accompanying drawings, in which- Figure 1 is a plan of a machine exemplify- 2o ing our invention, and Fig. 2 a vertical longitudinal section of the same.
In the drawings, 1 indicates a vat adapted to receive the liquid to be dealt with; 2, the upper surface of the liquid therein; 3, a hollow metallic cylinder mounted in suitable bearings and dipping the lower portion of its periphery into the liquid in the vat; 4c, inletpipe for the thermic fluid or liquid into the cylinder; 5, outlet-pipe for the thermic fluid or liquid from the cylinder, the inlet and out let pipes being illustrated as communicating with the interior of the cylinder through its opposite end journals; 6, a gear upon one of the necks of the cylinder; 7, an inlet-pipe for admitting to the vat 1 the liquid to bedealt with; 8,a doctor engaging the periphery of cylinder 3 at a point over the liquid in the vat at that side of the cylinder approaching the liquid; 9, a second vat arranged to receive 0 its supply of material from the doctor 8, the
construction shown in the drawings being such that the scrapings from doctor 8 will fall directly into vat 9 5 10, a second cylinder mounted and provided similarly to cylinder 4 5 3, but dipping the lower portion of its periphery into the liquid in vat 9; 11, a doctor arranged to scrape cylinder 10; 12, a catch-box arranged to receive the scrapings from doctor 11; 13, a gear on one of the necks of cylinder 10; 14:,a shaft parallel with the axis of cylinder 3 and having a pinion engaging gear 6; 15, tight and loose pulleys on shaft 14, the arrangement being obviously such that abelt engaging pulleys 15 may be employed in imparting rotary motion to cylinder 3; 16, a
shaft parallel with the axis of cylinder 10 and carrying a pinion engaging gearl3; 17, a gear fast on shaft 16; 18, a shaft parallel with shaft 16 and carrying a pinion engaging gear 17,
and 19 tight and loose pulleys on shaft 18,
the arrangement being obviously such that a belt upon loose pulleys 19 may impart rotary motion to cylinder 10 at a low rate of speed as compared with cylinder 3.
Assume that the liquid to be dealt with is,
3 is to be set in motion in the direction of the arrow, and the liquid to be dealt with is introduced, as at inlet 7, and maintained in the vat at substantially the same level as evaporation takes place. The cylinder as it turns in the liquid in the vat will become wetted or coated thereby. As the coated surface of the cylinder travels upwardly out of the vat the heat of the cylinder causes the lighter liquid portions of the matter to evaporate from the coating, the vapor going to the atmosphere S5 and leaving a semimoist coating upon the cylinder. This coating is scraped from the cylinder by doctor 8, which delivers it to vat 9. The semiliquid in vat 9 becomes similarly operated upon by cylinder 10, which yields a 0 dry coating which is scraped off by doctor 11 and delivered to catch-box 12.
In the example of liquid above referred to the thickening of the liquid was eflccted by the addition of heat to it, the heat resulting 5 in the evaporation of the lighter liquid portions of the matter. Assume, now, that the liquid to be dealt with is oil or lard, to be thickened by abstracting heat from it. In
such case the liquid will be supplied to vat 10o In such case in the 70 1, as before; but the thermic fluid or liquid supplied within the cylinders will be coldas, for instance, refrigerated air or refrigerated water or brine. The rotating cylinders take up liquid in the form of a coating on the cylinders, heat becoming transferred from the coatings to the metalof the cylinders and to the thermic agent within the cylinders, resulting in the final solidification of the coating upon cylinder 10, this cylinder becoming scraped off by doctor 11.
We claim as our invention In a machine for thickening liquids, the combination, substantially as set forth, of a vat adapted to receive the liquid to be dealt with, a hollow metallic cylinder mounted for rotation in said vat with its lower portion dipping into the liquid therein, a second vat, a second cylinder mounted to'turn in said second vat at a lower speed than the first cylinder, a doctor engaging the first cylinder and arranged to scrape the coating therefrom and deliver it to the second vat, and a doctor engaging the second cylinder and arranged to deliver its scrapings to a suitable receiver.
