H. J. J. BlGUM ROTARY COOLING DRUM Filed June 8, 1920 Patented May 4, .1926.

ROTARY COOLING DRUM.

Application filed June 8,

To all whom it may concern:

Be it known that I, HAN S JRGEN J ENSEN BIGUM, subject of the King of Denmark, residing at Copenhagen, Denmark, have invented certain new and useful Improvements in Rotary Cooling Drums, of which the following is a specification.

The invention relates to an improvement in rotary cooling devices for cooling, solidll fying or crystallization of l1qu1ds, melted substances, emulsions, gelatine or the 11ke, for instance margarine emuls on.

In apparatuses of this kind the substance is fed into the workin surface of the rotary body, and is taken a ong on the same for a fraction of a revolution from the feeding point to a scraper which scrapes away the substance solidified on the worklng surface during the said ortion of a revolution.

90 The rotary bo y is ordinarily sha ed as a circular cylindrical drum whose c 1ndr1- cal surface is the working surface. he lat- .ter ma also be conical, however, or uite plane,

" rotary cooling bodies of th1s k1n d 18 that the cooling fluid used is ord1nar1ly a salt solution entering at one end of the ax1s of revolution of the coolin body and passing directly through the coo ing body nside of 80 the working surface of the same n order to escape at the other end of the ax1s of the cooling body.

As it is well known, the coeificient of heat transmission, for the heat passing from a 88 wall to a liquid flowin alon the same, de-

pends on the speed of ow o the l1qu1d. It is very important that speed should not be too low, and the resent invention has for its object to give t e c0oling li uld in coolmg apparatuses as hi h a s ee as possible during its flow along t e inside of the workin surface. 7

n cooling drums of the above mentioned kind, the cross-sectional area of the drum is a several times as large as the area of the supply channel for the cooling liquid and, for

this reason, the liquid passes only slowly through the cooling drum. Even if there be provided a cylindrical body within the same and co-axially thereto, it will be impracticable, for purely constructional reasons, to'make the cylindrical space between ut a common feature for most 0 the 1920. Serial No. aaasee.

the inside of the drum and the said cylindrical body so narrow that the cooling fluid passing through thesaid space will attain a suitably h i h speed, because such narrow channel wil easily become clogged.

Accordlng to the present invention a very considerable speed of motion may be attained, simultaneously with a suitable depth of channel, for the cooling liquid flowing .along the inside of the working surface by directing the liquid through one or more winding or meandering channels provided inside of the working surface, this surface forming one of the limiting walls of the channels.

The drawing shows various constructions of the invention.

Fig. 1 showing, in outline, a cooling drum v in end elevation,

Fig. 2 shows a longitudinal section of a cooling apparatus with a helical channel for the cooling liquid,

Fig. 3 a cross-section of the same,

Figs. 4 and 5 longitudinal sections of the outer portion of two different constructions of the cooling drum shown in Figs. 2 and 3.'

Referring to Fig. 1, 1 is a rotary body which is here supposed to be a cylindrical drum, 2 is the point of supply for the substance to be cooled, and 3 is the scra er which scrapes the cooled substance, an isforced towards the outer face of the drum 1 by a counter-weight 4.-.

Figs. 2 and 3 show one manner of constructing the cooling device of the cooling body. 5 is here a cylindrical jacket or drum whose outer surface 6 forms the working surface. Within the drum 5 and, preferabl coaxially thereto there is a hol ow body 7, while 8 is a helica rib provided between the inner face of the drum 5 and the outer cylindrical surface of the hollow body 7. 9 is a helical channel formed between the windings of. the rib and the bodies 5 and 7 and terminates at each end of the hollow body 7 in a cavlty 11 formed between the body 7 and the end walls 10 of the drum 5.

. 12 is the axis of revolution of the bodies 5 and 7 and is here, by way of example,

shown made in one with the body 7 13 are rovided channel for the cooling liquid, and passes through the shaft 12 and opens into one of the chambers 11, whence the liquid flows, in the directions indicated by the arrows, through the channel 9 to the other chamber 11 from where it escapes by way of a discharge channel 15 at the other end of the shaft 12. 16 are openings in the cylindrical wall of the hollow body 7, and connect the chambers 11 with the channel 9.

Instead of one single helical channel 9, several such may be provided between the bodies 5 and 7, and all these channels must then terminate in the chambers 11.

In the constructions shown in Fig. 2, the ribs 8 are made integral with the drum 5 and fit tightly about the outer cylindrical face of the body 7.

As shown in Fig. 4, the ribs 8 may also be made integral with the body 7 and fit tightly against the inner face of the drum 5. As shown in Fig. 5, ribs 8 may also be provided both on the member 5 and the member 7 which nibs must then fit tightly against each other.

Having now particularly described and ascertained the nature of my said invention and the manner in which the same is tobe performed, I declare that what I claim is 1. A rotary drum for cooling fatty substances and emulsions comprising a cylinder on which the material to be cooled is supplied in a. thin layer, a scraper for removing said material from the cylinder, a second cylinder inserted in the first cylinder, an annular narrow space between said two cylinders and a rib arranged in said annular space so as to form a narrow helical channel throu h which a cooling liquid may flow.

2. g rotary drum for cooling fatty substances and emulsions comprising a cylinder on which the material to be cooled is supplied in a thin layer, a scra er for removin said material from the cy inder, a secon cylinder inserted in the first cylinder, an annular narrow space between said two cylinders and a rib integral with the first cylinder and arranged in said annular space so as to form a narrow helical channel through which a cooling liquid may flow.

In testimony whereof the foregoing speci. fication is signed.
