ratus for the rapid congelation of various articles, and chiefly alimentary articles such as meat, fish or the like, for the better preservation of the saidarticles.

The apparatus according to the invention consists essentially of a drum which is divided by longitudinal and radial partitions into chambers adapted to contain the articles or substances to be frozen. The said drum is rotatable on its axle and is provided at the central part with conduits supplying the freezing liquid and characterized by the particular feature consisting in the fact that they will deliver a shower of liquid upon the substances in said chambers only when the chambers are situated below the horizontal plane passing throu h the axis of the drum. After acting upon t e said substances to be frozen, the liquid flows out through perforations in the external casing of the drum into a tank in which its temperature isagain lowered,-

and it returns thence into the apparatus.

The said apparatus according to the inven-' tion will serve for the continuous congelation of large quantities-of articles, and chiefly fish which are thus treated as fast as caught. The

importance of this lies inthe fact that itis distinctly advantageous to freeze the fish whole and in their natural state as taken from the water. Living fish in their natural occurrence are covered by a protecting slime. If that slime is fixed on the fish and the fish frozen therein, it remains a protecting en-. 'velope, but that advantage cannot be gained capture is possible.

Fig. 5 is a diagrammatic sectional view analogous to Fig. 1, showing two similar apparatus functioning in series.

Referring to Figs. 1" and 2, the apparatus essentially comprises a-stationary cylinder 1 having the perforations 2 on its lower half.

The axle 3 of, the said cylinder is hollow and is pierced with the perforations 4. 11* drum 5 is mounted concentric with the-c linder. I and is rotatable about the latter. he said and comprises in the interior a set of radial partitions 7 which come almost in contact "drum is closed at the ends by the plates 66 with the stationary distributing cylinder 1.

The worm wheel 10 keyed to the drum 5 serves to rotate the latter by means of the worm 11 driven by a hand wheel 12.

The whole apparatus thus composed'is placed within the tank 13 in which is disposed a'perforated element'or-strainer 14 cooperating with the drum 5.

In the tank 13 is disposed the evaporating coiled pipe 15 of a refrigerating machine,

said tank preferably having a removable side 16 for facilitating the insertion of the coil titions 36 corres ployed as oil; of

two bearings 2324 and is rotated, as hereinbefore described, by a worm wheel 25 and a worm 26; said drum rotates within a tank 27 to which the said bearings are secured.

. 5 Each chamber contains one or more perforated tubes 28 and each tube carries at one end a flange 29 provided with packing, and the other end is threaded and carries a nut j 30, so that the said tubes can be removably mounted in relation to the apertures 31 of the cheeks 3233 which are mounted on the shaft 22 and carry the end plate 34 of the said drum. The cheek 32 is recessed, and j the recess-is divided into chambers 35 by parndin to the partitions of the chambers o the rum. Each tube 28 communicates with a corresponding chamber? 35 which is providedon the other side with apertures 37, so that during the rotation of the drum .the said zsertures will register with the ports 38 form in the lower part of the 7 bearing 23 which is suitably supplied with the cooling liqu' The operation of the apparatus is as follows:

The substances to be frozen are loaded atA (Fi 1), and the cover 8 is then closed. The ban wheelisusedtorotatethedrum 5m the direction of the arrow by the width of one chamber, and this so chamber is loaded, and so on. When aloaded-chamber.

is situated below the horizontal plane passing through the axis of rotation, the substances therein will be-acted upon by the streams of liquid issuing from the apertures 2. As the loaded chambers return to the upper part, they are opened at B to be d1schar The strainer 14 part] surrounding e drum 5 serves to retain e said sub: 40 stances or other objects which might fall into the tank 13 due to im roper handling. The li uid in the tank shou d entirely cover the coi ed tube.

' Fig. 5 shows the apparatus operating in series, andthe apparatus are'rotatable in the direction of the arrows. The chambers: G and D are opened at the same time so that the articles'will proceed by gravity from the first into the second. After rotating in the the chamber D willeeome to .IX-- and will then be emptied by gravity.

- It will be seen that the articles to be frozen are so handled that fish are first subjected to the cold atmos here over the refrigerating liquid, thus pre iminarily fixing the slime on the fish so that it will not be washed ofi when subjected to the circulating liquid refrigerant. 7
