Patented Sept. 16, 1930 UNITED STATES PATENT OFFICE HERBERT FISCHER AND LASAR GRODNITZKY, OF DARMSTADT, GERMANY Our invention relates to cooling devices, and more particularly to cooling plates which are used in the manufacture of soap, fat, tallow, chocolate, and the like. Heretofore,
said cooling plates have been made from east or wrought iron, but we have discovered that various advantages may be obtained, if cool ing plates are made of pressed parts, and therefore, the object of the present invention is to produce cooling plates which are made from pressed or stamped parts, either with or without the use of pressed or rolled corrugated sheet metal.
In the accompanying drawing, in which We have shown, by way of illustration, various embodiments of our invention, Fig. 1 is a plan view of a complete cooling apparatus with the top plate removed; Fig. 2 is a longitudinal section along line 22 in Fig. 1, and Fig. 3 is a transverse section along line 33 in Fig. 1; Fig. 4 shows a detail, partly in section, on a larger scale; Fig. 5 is another sectional detail view on a larger scale; Fig. 6 is a similar view as Fig. 1 showing a modification; Fig. 7 is a longitudinal section along line 77 in Fig. 6; Fig, 8 is a transverse section along line 88 in Fig. 6; Fig. 9 is an enlarged section through the frame of the device; Fig. 10 is a plan view of a modified form of the frame; Fig. 11 is a section along line 1111 of Fig. 10; Fig. 12 is an enlarged detail section on the line 1212 of Fig. 10; Fig. 13 is a plan view of a modified cooling device with a portion of the top plate broken away; Fig. 14 is a longitudinal section therethrough along line 14.14:1Il Fig. 13 and Fig. 15 is an enlarged detail view.
The cooling plate shown in Figs. 13 comprises two metal plates 1, 2, which are pressed out or stamped in such a way as to form ribs 3 extending from the one edge of the plates and rising at ornear the opposite edge, as clearly shown in Fig. 3, the ribs thus forming a series of troughs open at one end. The two plates are so placed together that the ribs 3 of one plate alternate with those of the other, as clearly appears fromFig.2,the open ends of the troughs formed by the ribs of one plate being on one side of the plates while the open ends of the troughs formed by the ribs DEVICE 134,634, and in Germany, September 12, 1925.
of the other plate are on the opposite side. The ribs, besides imparting the required stiffness to the entire cooling device, also thus contribute to a favorable distribution of the cooling medium. The troughs formed by the ribs 3 also receive blocks 4, placed at the open end of each trough, which blocks, as shown in Fig. 4, are held in place by screwbolts 5 passing through the ribs. The blocks a may be welded or otherwise secured to the cover- plates 6, 7 shown in Figs. 2, 3 and el, which cover plates are thin plates preferably made of nickel, but which, of course, can be made of any other suitable material. Said cover plates are also preferably welded to the plates 1, 2 which, for this purpose are chamfered, as shown at 8 in Figs. 1 and 2, to provide space for the welding seam.
The last rib 3 at or near one end of each plate 1, 2 is preferably made shorter than the other ribs as clearly shown in Fig. 1, and in the remaining portion a channel 9 is provided for the passage of the material to be acted upon, said channel passing through the cooling device without communicating with the interior thereof. This channel 9 which is shown more clearly in the sectional view of Fig. 5, may be made in the shape of a truncated cone, two flanged tubular and frustoconical portions 10, 11 being pressed concentrically together in opposite relation to each other, and respectively attached to either of the two plates 1, 2.
In the modification of the cooling device shown in Figs. 6-8, the plates 12, 13 are provided with troughs formed by walls let which are pressed or stamped out from the metal of the plates 12, 13. These troughs also extend from one edge of each plate to near the opposite edge in alternating arrangement thus constituting a tortuous passage for the cooling medium, while at the same time imparting stiffness to the plates 12, 13. The latter, at their ends are bent off as shown at 15 in Fig. 7 to form spaces for the welding seams whereby the cover plates. 16, 17 are secured to the plates 12, 13. This is more clearly shown in the enlarged view of Fig. 9.
Near the periphery of the plates 12, 13, there is provided a frame 18, which, as shown in Figs. 10-12, may be made from pressed parts, such as channel shaped members 19 and suitable stiffening members 20. Said frame, as shown in Fig, 9 is likewise welded, or otherwise secured, to the plates 12, 13 along the edges thereof.
As shown in Figs. 6 and 7, an inlet opening 21 is provided at or near the one end of the cooling device for the cooling medium to enter the same, to pass beneath the cover plates in a sinuous path and to leave the device by an outlet opening 22 (Fig. 6) provided at or near the other end of the device. The ribs or walls of the cooling plates act as baflles to divert the flow of the cooling medium.
The hollow portions of frame 18 may be left empty, or they may be filled with any suitable material to facilitate heat exchange, and, of course, the frame may be constructed in any other way than shown in Figs. 1012.
The device as above described, while equally adaptable both for heating and cooling is more especially designed for cooling soap, fat, parafiin, chocolate, and the like as has been stated above.
A further modification of the device is disclosed in Figs. 13, 14 and 15. The cooling device as shown in said figures comprises two plates 23, 24, which along their edges are connected by a frame 25. Between the two plates which are preferably made from nickel plated steel sheet metal, are pressed or rolled parts 26 which form trough shaped members for the flow of the cooling medium and which are secured to the plates 23, 24. The channel for the passage of the material to be treated is shown at 27 in Fig. 13. At 28 is shown the inlet opening and at 29 the outlet opening for the cooling medium.
The members 26 may be secured to the plates 23,24 in any desired manner, but are preferably welded thereto, and the frame 25 is likewise preferably secured to the plates 23, 24v by welding.
Instead of the pressed or rolled member 26, also rolled or pressed corrugated sheet metal can be placed between the plates to form a passage for the cooling medium.
