UNITED STATES ARNOLD FAITELOWITZ, or BERLIN, GERMANY.

APPARATUSFOR THE PRODUCTION PRESERVES OF VEGETABLE MATTERS OF I UNLIMITED DUB/ABILITY.

Application filed March 8, 1924, Serial No. 697,907, and in Germany July 29, 1921.

This invention relates to an apparatus for the production of preserves of vegetable matters of unlimited durability. The invention has for its object to dry the vegetable matters in such a manner that they preserve permanently the colloidal nature of the original matter, the swelling capability) of the same, the enzymes and the capa ility to gelatinize, all this being obtained without addition of sugar,-salt or the like. With this object in view the apparatus is constructed in such a manner that the vegetable matter is dried only to pasty consistance, as the vegetable matter spread in a thin layer upon the drying surface is continuously agitated during the drying with the aid of a roller, cylinder or other suitable means so that the surface of the layer is torn and the formation of a dry skin is prevented, and the moistness is maintained uniform at all points of the layer.

In the accompanying drawing the improved apparatus 18 shown in Fig. 1 in longitudinal section.

Fig. 2 shows the roll and Fig. 3 the scraper. 1

,The' apparatus consists essentially of several, for instance three, drying plates or tables 1,2, 3 arranged the one above the other on the top surfaces 4 of which the-mass to be dried is spread out. Under the lowest plate 3 a heating chamber 5 filled with I water is arranged "which is heated by means of a steam serpentine -6. The steam generated from the water heats the plate 3 and flows through a conduit 6 under the other plates of the drying apparatus. A movable frame 7 which carries the essential means for the drying process is. moved over the plates 1, 2, 3. These means consist of rolls 8 which are revolubly mounted on arms 9 and i which are tilted by a rod 10 with the aid of a hand lever 11. When the hand lever 11 is depressed the rolls are lowered upon the material to'be dried andif the carriage is being moved in .two directions the mass on the plates is rolled. Scrapers 12 serve to lift the dried pasty mass from the drying plates, in arms 13. The scrapers are cont-rolled by a hand lever 14. The vegetable matter to be dried is charged on the plates by means of tiltable troughs 15 which are connected with one another by rods 16 having at the lower the scrapers being revolubly mounted i zid a roller l6 guided in an inclined guide lf the movable frame 7 is being moved for instance from the left to the'right end the troughs 15 are gradually tilted uniformly so that the liquid mass is poured upon the surfaces of the plates.- After this has been done the rolls 8 are lowered upon the drying platesby the depression of the hand lever 11 and uniformly rolled over the mass to be dried so that no portions of the same are excessively heated. When the drying process' has been finished the rolls are raised.

again and the scrapers 13 are lowered which scrape off the dry pasty mass and push the same towards one endof the drying plates whence it may be removed.

As the drying plates are never quite plane the rolls as well as the scrapers are composed of several parts adjustable with regard to one another.

Fig. 2 shows a roll the axle 18 disks 10 are mounted, the bores axle so that the disks can move with, regard to the axle and are all pressed uniformly .on the drying plates. The scrapers are also composed each ofseveral lamellae 2O revoluble independently. of one another around the axle 21and pressed against the plates by the action of springs 22 (Fig. 3).

The frame 7 is moved'to and fro by any on a larger scale. On 4 of which are Wider than the diameter of the convenient device for instance by a rotating conveyor band movable in both directions.

I claim 1. Apparatus for the production of preservesof vegetable matters of unlimited durability comprising in combination a number.

of superposed drying plates,.means for heating said plates by steam,

in vertical direction adapted to be rolled over the drying mass on the plates in order to prevent excessive heating of the mass and for'uniformly mixing the same, said rolls consisting each of an axle and of a convenand rolls movable in vertical direction adapted to be rolled over for the production of pre- I ient number of disks mounted on said, axle so that they ma displace themselves with regard to said ax e in order to uniformly roll over irregular surfaces of the plates.

3,. Ap' aratus for the production of preserves 0 vegetable matters of unlimited durability comprising in combination a number of superposed drying plates, means for heating said plates by steam, and rolls movable in vertical direction adapted to be rolled over the drying mass on the plates in order to prevent excessive heating of the mass and for uniformly mixing the same, said rolls consisting each of an axle and of a convenient number of disks mounted on said axle so that they may displace themselves with regard to said axle in order tovuniformly roll over irregular surfaces of theplates, a frame in which said rolls are revolubly mounted, and scrapers revolubly mounted in said frame one for each drying plate, said scrapers consisting each of an axle and of amellae revolubly mounted on said axle.

4. An apparatus for the production of preserves of vegetable matters of unlimited.

durability, comprising in combination a number of superposed drying plates, means for heating said plates by steam, .rolls adapted to be rolled over the drying mass on said plates in order to prevent excessive heating of the mass and for uniformly mixing said mass, a frame in which said rolls are revolubly mounted, scrapers revolubly mounted in said frame, one for each drying plate, tiltable troughs mounted ,in said frame for charging the mass-of vegetable matters to be dried "on the several drying plates, and means for uniformly tilting said troughs if said frame moves Over said plates.

y In testimony whereof I afiix my signature.
