APPARATUS FOR EXTRACTING TERPENES AND ROSIN.
Specification of Letters Patent.
Application filed September 28, 1906. Serial No- 280,486.
Patented Oct. 9, 1906.
To all whom it may concern.- Be it known that I, GEORGE A. KERR, of
Lynchburg, in the county of Campbell and provide a machine having means wherebythe extraction of" terpenes and rosin from rosin-bearingwoods may be effected during the single assage of wood through the still, the wood being continuously fed in at one point and continuously discharged at another. A further object is to enable the terpenes to be quickly and effectively extracted in a single and continuous passage thereof through the still.
According to my invention the chips or slivers of pine or other rosin-bearing wood'are fed into one end of a still throughwhich they are caused to travel, steam being supplied to only so much of the wood as it can liberate of terpenes, the wood bein constantly subjeoted to a fresh supply 0 steam. The wood freed of the terpenes passes into an extractor containing an alkaline solution which is kept at such temperature that the wood when discharged by a conveyer from the extractor will be freed from all rosin, which is taken up by the alkaline bath, the latter flowing off through a suitable outlet.
The invention will be hereinafter fully set forth, and particularly pointed out in the claims. I
In the accompanying drawings, Figure 1 is a vertical longitudinal sectional view. Fig. 2 is a transverse sectional view on line 2 2,
Fig. 1.
Referring to the drawings, 1 designates the receiving-conveyer, which is shown in the form of an endless screw 2, inclosed by a circular still-casing 3. The conveyer-shaft 4 is hollow and designed to receive atone end steam from an engine or boiler, exhauststeam being preferable. Between the several convolutions of the conveyer, save those directly beneath the charging-hopper 5, the shaft 4 is equipped with outletorts 6, through which the steam escapes to t e wood confined between such convolutions. The shaft also carries radiallyvextended arms 7,
planes, so as to agitate or cascade the chips as they are forced forward by the conveyer, and
thus insure their being fully acted upon by the steam. Mounted longitudinally above the casing 3 is a receiving-chamber 8, connected with the former by a series of pipes 9, so that the steam charged with terpenes passing from the still-casing 3 will enter receiving-chamber 8, whence it passes to a condenser. (Not shown.) By omitting the outlet-ports fromthe shaft at the receiving end ofthe still no steam is liable to escape through the ho per. The wood as it travels through the sti l is constantly subjected to a fresh supply of steam, and the ter one-laden steam passes directly off instead 0 having to travel through an extended amount of Wood. This is due to the fact that the convolutions of the screw conveyer divide the wood into equal helical portions, and the steam admitted to the spaces defined b the several convolutions contacts with o y so much wood as it can free, in part at least, of terpenes.
10 deslgnates a second screw conveyer,
preferably below and parallelwith the first-" mentioned conveyer, its casing 12 being connected with the casing 3 by a cohduit 13, so,
that the wood as it is discharged from casing 3 will fall into casing 12. This secondconveyer is constructed similarly to that before described; but the casing wherein it is located is preferably of U shape in cross-section, as shown in Fig. 2. Within this casing is an alkaline bath through which the wood freed of the terpenes is forced to travel. This alkaline bath and the wood are kept at the proper temperature by the steam fed thereto through the conveyer-shaft, which latter has escape-ports 14 formed therein throu hout its length.- The-casing 12 at its disc arge end has a trough or chamber 15, the bottom of which is beneath the bottom of the casing, and from this trough extends an outlet-pipe 16, which is located as near the axial center of the conveyer as possible, so as to always maintain the bath at a suflicient depth within the conveyer-casing. The rosin-containing solution flows ofi through the pipe 16,
from the ho per-being constant.
taken up by the constantly-rotated screw as it escapes into the spaces defined by the several convolutions will act uniformly upon all of the wood. The steam thus carrying off the te enes will immediately escape through the pipes 9 into the delivery chamher 8, and as the wood proceeds on its travel through the casing it is continuously agitated and constantly subjected to a fresh supply of-steam, with the result that as it reaches the discharge end of the still-casing it will be entirely freed of the T'ter enes. There'upon the wood falls through con uit 13 into the casin of the rosin-eftractonthrough which it will e caused to travel by the endless conveyer being agitated by the radial arms, as in the turpentine-extracting still. The alkaline-bathwithin the rosin-extractor, as well as the wood, is kept at proper temperature by the steam escaping through the tubular shaft of the conveyer. By the time the wood reaches the discharge end of the extractor all the rosin thereof will havebeen taken up b the alkaline bath, and the latter will flow 0 through the outlet 16, while the Y wood is conveyed away by the conveyer 17.
I claim as my in've'ntion 1. An apparatus of thecharacter herein described, comprising a still or digester, means for extracting terpenes from the wood while in such still, an extractor for receiving the wood from said still, and means for extracting the rosin from the wood while in such extractor.
