DEVICE FOR DEEP PRESSING OF PLIESSPAGE FOOD

The invention relates to a device for deep freezing from flowable foods, like minced or steamed spinach, to small separate particles. The particles should therefore be freely movable in relation to one another if they in a package or the like. are included, so that one of the packaging exactly the amount of frozen food you want Food can be found.

The device comprises two cooperating with one another endless tracks that lie against one another over part of their length to create small separate spaces between them for the Forming food, the endless webs with a freezer cooperate to freeze the food in the small separate rooms. The device is characterized by that one endless web is provided with transverse grooves and the other endless web is provided with longitudinal grooves is, wherein the grooves of the two endless tracks are designed in relation to each other that they are against each other

lying lanes together form the small separate spaces for the food. The device according to the invention is thus designed in such a way that it enables the flowable foodstuff to freeze rapidly to form small separate particles, at the same time as the particles can be dispensed by simple means. -: .--- _: '

The invention is based on the one as an example

selected embodiment of the device according to the invention and illustrative of the shape of the particle produced therein Drawing described in more detail below. It shows:

Fig. 1 is a longitudinal section of the device, ™ Fig. 2 is a section along the line II-II in Fig. 1,

Fig. 3, on a different scale, the produced particle in three mutually perpendicular cracks ^ /

The device comprises the two cooperating, endless conveyor tracks 1 and 5 ₃ which abut one another over part of their length in order to form small separate spaces between them for receiving the food. The track 1 is an endless conveyor belt, while the track 5 is a rotating drum or the like. is. ■ -.

Ä The conveyor belt 1 lies over part of its length

against the drum 5, over about three quarters of the drum circumference, so that small separate spaces for receiving the food to be frozen are formed between the conveyor belt 1 and the drum 5. The drum 5 is located in a freezer for 3 _seconds so that the product is frozen into a solid form, while the two webs 1 and 5 lie against one another. According to the illustrated embodiment, the drum 5 is a cooling drum so that effective freezing is ensured. The product is in direct contact with the drum 5. .

The conveyor belt 1 has in its transverse direction

running grooves 2, while the drum'5 circumferential grooves 9 with the grooves 2 and 9 so formed in relation to each other are that they are in contact with the conveyor belt against the drum 5 1 together form the aforementioned small, separate rooms for receiving the food. The grooves 9 of the drum 5. are between rows of teeth 8 arranged next to one another on the circumference of the drum 5, the elevations between the grooves 2 engage in the conveyor belt 1 between the teeth of the rows of teeth 8 and thus form the small closed spaces.

The grooves 2 of the conveyor belt 1 are like those in FIG.

Drum 5 provided grooves 9 mainly semicircular f Cross-section, which is why the frozen particles 4 have the cross-section shown in FIG. 3. The particles 4 are thus basically bounded by two semicircular cylinder surfaces 10 and 11, which have axes perpendicular to one another. the Grooves 2 and 9 of the conveyor belt 1 and the drum 5 can, however also have other cross-sections, which is why the particles 4 generally of two single curved surfaces 10 and 11 with mutually perpendicular Axes are limited. The extremely slight curvature, which is the round shape of the Drum 5 originates. The size of the particles 4 can of course be within be varied within certain limits, but the · particles must be at least as big as peas, conveniently a little bigger.

The conveyor belt 1 runs with one part outside of the freezer compartment 3 »wherein it has a substantially horizontal part, which is against the drum 5 at the lower part of the Plant is running. If there is 12 on the mentioned lot, this is made up of e.g. Chopped or steamed spinach consisting of a flowable product

abandoned, which can be dosed in a simple manner. To the mutual system of conveyor belt 1 and drum 5, with the Product is frozen to a solid form, the product is placed on the conveyor belt 13, which takes it away. The product is made then made up of small separate particles 4 which when in packaging are introduced, are freely movable in relation to each other.

After resting against the drum 5, the conveyor belt 1 runs over a deflection roller 7 * which transports the frozen particles 4 detaches from the conveyor belt. This is achieved in that the band 1 is continuously folded away from the drum 5, the through the wave shape of the band created grooves 2 by the extremely small thickness of the tape can be deformed.

At least one knife can interact with the drum 5, to detach the particles 4 from it. In the case of the preferred embodiment act endless lifting belts 6 with the Grooves 9 of the drum 5 together, these belts 6 against the _. Bottom of the grooves 9 in the area where the conveyor belt 1 rests against the drum 5 while it is in the one Area where the drum 5 from the conveyor belt! is free from the grooves 9 of the drum may differ.

The · invention is not limited to that described above and shown on the drawing, _s but may be modified within the scope of the claims.
