The plant is constructed so that the sole sweeps the oysters on the surfaces of the conveying belts 311 and 411 so that the oysters are separated from the conveying belts 311 and 411.

As shown in Fig. 2, the transfer conveyors 31 and 41 are provided with their ends staggered with each other.

That is, the discharge end of the conveying conveyor installed on the upper end is shorter than the inlet side end of the conveying conveyor installed on the lower side so that the oyster falling by the upper conveying conveyor and falling to the lower conveying conveyor can stably fall on the upper surface of the lower conveying conveyor. The inlet end of the uppermost conveying conveyor was exposed to the chambers 30 and 40 so as to overlap with the ends of the conveying means 6b and 6c, and the outlet end of the lowermost conveyor was also chamber 30 ) So that the oyster discharged therefrom can fall to one end of the transport means (6c) installed in the lower portion.

Each of the transfer means 6a, 6b, 6c shown in FIG. 1 also has the same structure as the transfer conveyors 31, 41 described above, but is exposed to the outside of the chamber.

The low temperature hot air dryer 5 includes a heater 5a at one side of the chamber 50 in which a plurality of doors are formed at one side thereof; A blower (5b) which sucks and discharges the air in the chamber (50) so that the heat generated from the heater (5a) is spread evenly inside the chamber; It is composed of one or more carts 51 which are installed to be movable in the chamber 50 to move the pallet.

As described above, the low temperature hot air dryer 5 is a means for slowly drying the oysters to dry them to the inside of the oysters. When the temperature inside the chamber 50 is too high, only the surface of the oysters is dried and hardened. As described above, it is preferable that the internal temperature is maintained at 40 ° C to 60 ° C.

The heater 5a and the blower 5b are similar to those of the conventional oyster drying apparatus, and a detailed description thereof will be omitted.

As shown in FIG. 5, the cart 51 constituting the low temperature hot air dryer 5 is provided with a pallet supporter 51a supported by a frame in multiple stages, and palletized in multiple layers by the pallet supporter 51a. 51b is laminated.

The trolley 51 on which the pallet is placed is an inlet 50a of the low temperature hot air dryer 5 as shown in FIG. 4. It is pushed into the interior of the chamber 50 through the), the trolley 51 pushed into the inlet (50a) is pushed inward by the balance bushing means (52).

The reason for installing the balance bushing means 52 is to push the cart 51 pushed into the chamber 50 through the inlet 50a to the inside of the chamber 50 with the outlet 50b. When the carts 51 are arranged in a line, the large number of carts are too heavy to be pushed by the force of a person, and the above-described balance bushing means 52 is installed to push the carts at a time.

The trolley pushing means (52) includes a rack (52b) connected to one side of the push rod (52a) for pushing the trolley (51); It consists of the pinion 52c which moves the said rack 52b by the drive of the motor 32d.

As shown in FIG. 5, when the trolley 51 enters through the inlet 50a of the chamber 50, the motor 32d is driven so that the pinion 52c moves the rack 52b into the chamber 50. And the push rod 52a pushes the trolley 51 to move the inside of the chamber.

A wheel 52e may be installed below the rod 52a to allow the rod 52a to be moved more easily.

The process of drying the oyster using the oyster drying device configured as described above has already been described in the description of the drying apparatus, but collectively described as follows.

First, the process of making the first oyster, gourd, rinsing and the second boiled oysters are already known, so the description thereof will be omitted.

The drying process which is the gist of the present invention is the hot hot air drying after about 25 minutes to 40 minutes with high temperature hot air of about 80 ° C to 100 ° C in order to remove the moisture buried on the surface of the oyster which has undergone the secondary cooking. In order to allow the surface of the oysters to dry slowly, a medium temperature hot air of 60 ° C. to 80 ° C. is supplied for 20 minutes to 30 minutes. It is made by a low temperature hot air drying process for about 10 to 15 hours by low temperature hot air of 40 ℃ to 60 ℃.

As described above, the setting of the temperature in the high temperature hot air drying process may vary according to the temperature or humidity of the air, and the drying time is adjusted according to the temperature.

Of course, the intermediate temperature drying process may also vary in time depending on the temperature as in the high temperature drying process.

However, the temperature setting in the high temperature and medium temperature drying process should be set in consideration of the temperature and humidity of the air as described above, so as not to adhere to the conveying conveyor or the tray during the drying process of the oysters. It should be allowed to dry slowly so as to be possible.

Therefore, in the low temperature hot air drying process, the low temperature hot air is gradually adjusted from a high temperature to a low temperature for a predetermined time, so that heat is gradually transferred to the inside of the oyster, thereby allowing drying to the inside of the oyster.

As described above, by installing a medium temperature hot air dryer, the heat applied to the oyster can be adjusted to not only prevent the oyster from sticking to the conveying conveyor, but also to slowly transfer heat to the oyster to dry the inside of the oyster.
