[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a continuous freezing apparatus used to freeze fresh foods and the like continuously while moving them on an endless conveyor.

[0002]

2. Description of the Related Art In a conventional continuous freezing apparatus, as shown in FIG. 4, coolers 5, 5 are provided in a housing 4, which is covered with a heat insulating panel above an endless conveyor 3 into which an object to be frozen is fed. Two blowers are provided before and after in the feed direction, and the blower ducts 1 and 2 are provided with blow-off ducts 1 and 2 in which cool air blown from the coolers 5 and 5 are provided to face each other.
It is designed to be sprayed on the object to be frozen on the conveyor 3 through 2 and 12. The outlets 12a, 12a of the blow-out ducts 12, 12, whose diameters have been narrowed, fall vertically on the conveyor 3, and the objects to be frozen on the conveyor 3 have a uniform strength continuously. Cold air is blown from a certain part.

[0003] The cool air blown to the frozen object passes through the suction ducts 13 and 13 behind the cooler and is sucked into the coolers 5 and 5 to form a cool air circulation cycle.

[0004]

The conventional continuous freezing apparatus is configured such that cold air is blown from a fixed portion to the frozen object on the conveyor 3 continuously and uniformly. When trying to freeze various foods with different freezing conditions, there was a problem that it was not possible to spray effective cold air. In addition, the outlet ducts 12, 1
2 has a structure in which the inside of the wind tunnel is concealed, so that there is also a problem that an important cleaning operation as an apparatus for handling food is difficult.

The present invention has been proposed to solve the above-mentioned problems of the prior art, and can effectively freeze various foods having different freezing conditions, and can easily clean a blowing portion of cold air. It is an object of the present invention to provide a continuous freezing apparatus capable of performing the above-mentioned steps.

[0006]

In order to achieve the above object, a continuous freezing apparatus according to the present invention is provided with an endless conveyor for transferring a frozen object in a front-rear direction in a lower housing covered with a heat insulating material. Coolers are provided facing each other at front and rear positions in an upper housing covered with a heat insulating material above the endless conveyor, and a plurality of partition members are provided at a lower position between the coolers so as to be movable in the front and rear direction and detachably. , These partition members, the front and rear coolers and the upper housing define an upper space as a pressure chamber,
The lower space on the endless conveyor side is partitioned by the partition member and the lower housing to form a cooling chamber, and cool air blown from the cooler is blown from the outlet of the gap between the partition members to the frozen object on the endless conveyor to be cooled, Thereafter, cool air is sucked from behind the cooler to form a cool air circulation cycle.

[0007]

According to the above construction, the size of the outlet between the partition members can be freely set by moving or removing the partition member, and the outlet can be formed at an arbitrary position on the conveyor. it can.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a continuous freezing apparatus according to the present invention. An embodiment of the continuous freezing apparatus is shown in the configuration diagram of FIG. In this figure, in a lower housing 1 covered with a heat insulating panel, an endless conveyor 3 stretched between front and rear rollers 2 and 2 is driven in a direction of an arrow P in which an object to be frozen is transferred. Is provided.

In the upper housing 4 covered with a heat insulating panel above the endless conveyor 3, two coolers 5, 5 are provided in front and rear of the cooler 5, 5 facing each other. Blowers 6 and 6 are provided on the front part, respectively. Blowers 6, 6 are provided on the upper front of the blowers 6, 6.
Cold air blow-out guide plates 7, 7 are provided in order to blow cold air blown out from the endless conveyor 3 side.

On the lower side between the front and rear coolers 5, 5, a plurality of flat partition members 8 for separating the upper housing 4 and the lower housing 1 are provided as shown in FIG. 9 is provided. By providing these partition members 8, the upper space S1 defined by the partition members 8, the front and rear coolers 5, 5 and the upper housing 4 forms a pressure chamber, and the lower space S2 on the endless conveyor side is cooled. Room.

The plurality of partition members 8 are movable in the front-rear direction along the holding grooves 9 and 9 and are detachable.
By moving these partition members 8 to adjust the installation position or by removing some of the partition members 8, the amount and speed of blowing cold air from the outlet 10 formed in the gap between the partition members 8, as well as the outlet 10 positions can be adjusted.

The cold air blown out from the outlet 10 in the gap of the partition member 8 is blown onto the object to be frozen on the endless conveyor 3 to freeze the object to be frozen, and the traveling direction of the endless conveyor 3 or the reverse direction as shown by the arrow. Flows along the conveyor in the direction and is sucked into the coolers 5, 5 from the suction portions 11, 11 behind the coolers, forming a circulation cycle of cool air.

As described above, in this continuous freezing apparatus, by moving or removing the partition member 8, an outlet of an arbitrary size is provided at an arbitrary position instead of at one position in accordance with a target food to be frozen. 10 can be formed,
Various frozen objects having different freezing conditions can be effectively frozen.

Although a flat plate is used as the partition member 8 in the above-described embodiment, a partition member 8 having a U-shaped cross section can be used as shown in FIG.

[0015]

As described above, according to the present invention, two front and rear coolers are provided in an upper housing covered with a heat insulating material, and a plurality of coolers are movable and detachably mounted on a lower side between the coolers. The partition and the lower space on the endless conveyor side were partitioned to move and remove the partition, so that the position and size of the outlet formed between the partition members were adjusted to the freezing condition of the frozen object. In addition, it can be arbitrarily changed, and effective freezing can be performed according to various types of frozen objects.

Further, since the partition member can be removed and washed, the blow-out portion can be always held in a sanitary manner, which is suitable as a food freezing device.
