IMPROVEMENT IN EVAPORATlNG-PANS.
Specification forming part of- Letters Patent No. 110,484, dated November 30, 1875; application filed April 23, 1875. I
To all whom it may concern.
Be it known that I, ALFRED W. J. MASON, a resident of the city of New Orleans and State of Louisiana, have invented a certain new and useful Improvement in Evaporating- Pans; and I do hereby declare the following to be a full, clear, and correct description of the same, reference being had to the annexed drawing making a part of this specification.
My invention is designed to economize in the-manufacture of sugar, 860.; and it consists in a new and novel mode of constructing evaporating-pans, in which cane-juice or other liquids may, at a low temperature, be rapidly concentrated and also rapidly cooled.
The construction of my improved pan and the manner of 4 operating the same will be readily understood by referring to the drawin g, on which Figure 1 represents a front view of my improved evaporator, and Fig. 2 a side or end view of the same.
A A, &c., are columns upon which the whole apparatus is supported. B is the bottom orlower half of the juice-pan, which is provided with a steam-jacket, as shown at O.
- a b are steam-pipes coiled closely around the inner sides and ends of B. These pipes take steam and discharge their condensations through their extreme ends, on which are fitted valves. a is the steam-valve, and a the valve for the discharge of the condensation of coil a, whileb is the steam-valve, and b the valve for the discharge of the condensation of coil b. c is a valve leading to the jacket b from the condensation-pipes, and c a valve for discharging condensations from the jacket. d d, &c., are a series of thin metal disks or arms secured to a revolving shaft, the ends of which operate in bearings (1. These disks, while revolving in the liquid, serve to expedite the evaporation, also to keep the mass of liquid of an even temperature, for it is well,
understood that the great loss generally experienced in the evaporations of saccharine and other liquids occurs from the intensity of heat generated in the immediate body of the same,
as it progresses in its density, preventing the globules or bubbles of gas produced by the heated surfaces now used for the evaporation,
not being able to escape through the dense liquid to the surface, and thus generating an and-fthe column for supplying hot air.
intensity of heat in the sirup, sloughing off the crystals into an undue quan' tity of molasses. D is a cover, which-is closely fitted to the pan, to which'it is secured by means of bolts or in any other suitable way. E is a flattened airsupply pipe, the upper end of which is about vent the condensations from falling back into the pan. It is also provided with a damper to regulate the escape. G is a hinged lid for the purpose of readily ascertaining the action or to enable the operator to gain access to the interior. H is a thermometer leading into the body of the material being acted on, so as to determine the heat of the same. I is a thermometer descending into the air-column, for ascertaining the heat of the air as it passes into the pan, which can be modified or otherwise by means of the gates in the cold-air column e and hot-air column f. K is a glass indicator, for showing the amount of liquor contained in thepan. The lower portion also acts as a trier during the operation. L L are triers for ascertaining the consistency of the material during the operation.
The method of charging is through the pipe M, and of discharging by means of the valveN.
The pipe 9 on the hot-air columnf is intended to relieve the flues in which the air is I heated, when the valve off is closed, preventing the hot air from entering the pan.
The mode of operating my invention is as follows, viz: A sufficiency of juice is let in the pan, through the pipe M, to cover the lower coil b, which will be ascertained by the liquid appearing in the glass indicator, the disks revolving from first. The steam is then let on through valve b The condensation-valve b is also opened at the same time. The currents of heated air are then thrown into the pan, sweeping the sides of the disks as they revolve and rapidly carrying away the evaporations through flue F, the charging still going on, until coil a is covered, Whensteam is let on at 2 i 1 10,484 ll valve or, the condensation-valve a being also opened atsame time, the operator determining the amount of juice entering the pan, so that an intelligent m anipulation can be efi'ected.
It being an impossibility to boil over, no mat! ter whether the juice be sour or sweet, owing to the action of the air upon thesurfaceof the liquor, the pan can be charged as high as the lid or air-pipe will allow.
As soon as it has been ascertainethby means a of the triers L L, that the operation is properly efi'ected, the operator may, as circumstances admit, either cool the material by closing the hot-air column f by its valve, and also at same time close the steam-valves a and b of the coils, and, opening the valve of cold-air column 0, introduce the cold air, and at the a proper temperature discharge the mass into either barrel, hogshead, box,'or cooler, through valve N.
It must be borne in mind that when the valve in hot-air column is closed the reliefvalve, should be opened, toyprevent thehotair-generating flues from burning.
In the construction of my improved apparatus thesteam-jacket of the lower section of a pan B may be omitted, and a singleshell substituted therefor.
Having described myinvention, whatI claim a as new, and desire to secure by Letters Patent,
1. In combination with an evaporating- .chamber, a pipe, E, having its, mouth flattened to provide a narrowdischarge, the width of which is nearly equal to the length of the vessel, and an escape-tube, F, the whole being a constructed for deliveringcurrents of air into an evaporating-pan for sweeping the surface of the liquid and expellingtthe evaporations thereof, substantially as described.
2. The pipes E F, cover D, pan B, provided with pipes a b, and revolving disks (1, the whole a being constructed and ;combined to operate, substantially as described.
3. The cover D of anevaporating-papz pipe E, and air-columns a f g, the whole being com:
.bined to operat Substantially as described ALFRED W. J. MASON.
