DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drying apparatus for drying small fish using far infrared rays and hot air.

[0002]

BACKGROUND OF THE INVENTION anchovy and Manufacturing of a conventional small fish, dried over the from boiled small fish, dried by the sun, or the drying device
The way to do was taken. The sun's is dependent on the weather
As a result, it is difficult to manufacture products as planned ,
It takes a lot of time and the drying equipment is dried by hot air
But performs a, energy efficiency in the drying in the drying apparatus rather poor, there is a problem that the quality is not constant.

For this reason, a drying apparatus is disclosed in Japanese Patent Laid-Open No.
Drying device of development using far infrared according to 2943
Was. For drying by hot air by using far infrared rays
The product is less likely to be overheated, but
It may still be overheated when the amount of
It was inferior in quality to sun-dried.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to utilize the characteristics of far-infrared heating and hot air drying to obtain a small fish that can obtain the same finish as sun-dried in a short time. Dry
Equipment supply .

[0005]

According to the present invention, several stages (two to six stages) of conveying devices are provided inside the drying device, and the boiled small fish is conveyed to the uppermost conveying device and dried. Inside the device
While transporting small fish, drop it from the upper stage to the next transport device,
Dry while transported by the transport device .

[0006] The air duct and blower inlet from the blower to the top of the drying apparatus is provided, Ru mount the heater in the air duct or blower inlet. Drying equipment from ventilation inlet
The hot air sent into置内 is delivered to the top from the transport device to a lowermost transport apparatus, and is provided at the bottom of the drying apparatus <br/> exhaust port. Temperature detection at the ventilation inlet and exhaust port
And a temperature sensor based on the temperature obtained by the temperature detector.
To adjust the heating value of the heater.

[0007] upper surface of each of the transport apparatus, according to established a plurality of far infrared heater, go to lower from the uppermost stage,
Reduce the number of far infrared heaters installed. Or, in the adjustable radiation heat of far infrared heater attached to each conveying device on surfaces of, the upper stage may be less toward the bottom row.

[Action]

[0008] transportation device of the top stages in the drying apparatus, since the small fish containing much Niaga' moisture is transported, never hot air blower inlet or al high temperature is overheated even hit,
The temperature of the hot air drops every time it passes through the conveyor,
It is transported by the lower transport device where the water content is low.
The small fish that has come to hit the hot air with a lower temperature ,
The amount of heat from the far-infrared heater is also large in the upper row, and
Not because, at risk of watery overheating that has become smaller
Drying in a short period of time
Small fish that is likely to overheat with low water content
In order to eliminate it, little change of small fish due to heat is less, and drying is quicker.

When the input amount of small fish is reduced,
The reason is that when the small fish reaches the lower conveying device, the upper small
When there are few fish, there is nothing to absorb heat, so hot air temperature is
This is because high-temperature hot air reaches the lower stage without lowering.
Temperature from temperature detectors installed at wind inlet and outlet
By adjusting the temperature of the heater by
Reduce the amount of heating when high temperature hot air reaches the step
Can be overheated even with small fish input
Is lost.

[0010]

An embodiment of the present invention will be described. The drying device includes a drying device main body 1 in which a far-infrared heater 11 is provided on the upper surface of the transfer device 10 and the transfer device 10 in several stages,
Drying apparatus ventilation duct 5 with a blower 4 and heater 12 in the upper body, drying apparatus body lower the exhaust port 8, the exhaust air duct parallel beauty to exhaust air fan 9, drying apparatus main body entrance 2 of the upper to small fish, and Small fish outlet 7 at the bottom of the drying unit
Consists of

As shown in FIG. 2, the transfer device 10 inside the drying device main body 1 is moved from the upper transfer device to the lower transfer device 1.
Guide plates 13 are provided at every other stage on both sides so that the small fish always enter the lower conveying device when the small fish falls to zero. Far infrared heater 11 provided on the upper surface of the conveying device, toward the bottom from the top, reduce the installation number, calorific value and
Adjust so that it becomes smaller . Adjustment of heating value, the hand adjustment to the voltage regulator or the like in the case of using an electric heater as a heat source of the far infrared heater 11, the case of using steam heaters adjusts at vapor pressure adjusting valve or the like.

A blower installed above the main body of the drying device;
Air duct provided with a heater 12, depending on the size of the dryer main body, installed one set or several sets. The temperature detection device 14 to the blower inlet port 6 and an exhaust port 8 is provided, the temperature adjustment of the heating <br/> heater. Further, the amount of air can be adjusted by adjusting the damper in the air duct or adjusting the rotation speed of the motor of the air blower. The transport device is made of a net to improve the flow of hot air. Further, a flat ventilation method is adopted so as to keep the static pressure in the apparatus at a weak negative pressure, and for that purpose, an exhaust fan 9 for exhaust is provided.

The small fish carry-in port 2 and the small fish carry- out port 7 to the drying apparatus main body may be mounted in the same direction or in opposite directions depending on the installation location.

The drying of the small fish is generated by the blower 4.
Hot air obtained by adding the heat of the heater 12 to the
This is performed by far infrared rays emitted from the heater 11.
You. High temperature hot air in the upper stage where small fish contains a lot of moisture
And dried rapidly by strong far infrared rays,
In the lower stage, the air is cooled by the
Dry to avoid heating. The hot air temperature is
6 and a temperature detecting device 14 provided at the exhaust port 8.
Adjusted based on the temperature at which it is served, the input amount of small fish
If the exhaust temperature rises because of
Lowering the wind temperature prevents overheating in the lower section.

[0015]

According to the present invention , a small fish is overheated.
Even if the input amount changes, it is possible to manufacture dried fish with consistent quality even if the input amount changes, it can be manufactured in a shorter time than the time required for sun drying , and it is possible to make planned production that is not affected by the weather Was .
