DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for manufacturing dried whitebait, and more particularly to an apparatus for selecting air from boiled whitebait.

[0002]

2. Description of the Related Art In general, a so-called "shirasu-boshi" manufacturing method, in which small fish caught in the sea is boiled and dried on the sun, is still used today. Because this manufacturing method is simple, small shrimp, small crabs, or needle-like plankton, etc., which are mixed in the raw material "Shirasu", are mixed into the product to reduce the evaluation in the market. The removal of such contaminants is performed by the air selection method.
In other words, in the conventional wind selection method, small fishes taken out of the kettle and dried are dropped from above, and the wind is sent from the side to separate them. Shrimp and small crab are removed.

[0003] On the other hand, with the diversification of tastes, the degree of drying has been favored from semi-dry products with a focus on taste to traditional completely dried products with a focus on preservability. Those that are not are becoming preferred, and the proportion is increasing due to improvements in storage and transport technologies.

[0004]

However, as in the prior art, in the above-mentioned sorting method in which small shrimp and small crab are lightly selected for their size, a small degree of dryness, which has just been lifted from a kettle and has a low degree of drying. Also, since small shrimps and small crabs also contain a large amount of water and are heavy, there is a problem in that the accuracy of the selection is reduced unless the wind hit on each of the selected fish is improved.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the illustrated embodiments. In FIG. 1, reference numeral 10 denotes a wind-screening device for drying whitebait. The wind sorting device 10 includes a sorting trolley 20 supported by caster wheels, and a belt conveyor 30 supported by the sorting trolley 20. As shown in FIG. 2, the sorting trolley 20 is provided with side plates 22 and 22 on both sides of a bottom plate 21 and supports an upper plate 23 and a lower plate 24 on which the structure is formed.
The partition formed forms an air passage D. The belt conveyor 30 is attached so as to penetrate the air passage D and to be slightly inclined. 12
Is a supply conveyor for supplying the sorted fish F to the belt conveyor 30. The supply conveyor is placed directly from a boiler (not shown) or dried and dried for about half a day.

The belt conveyor 30 is formed by winding a conveyor belt 34 between a driving roller 32 and a driven roller 33 supported by one end and the other end of a frame 31 having an upward U-shape in the longitudinal direction. Then, the support shaft 35 and the vibrator 3 provided at a distance of 選 from the sorting cart 20 are provided.
6 are supported so as to be tiltable. The vibrator 36 vibrates the frame 31 in the vertical direction. Therefore, the belt conveyor 30 is provided to rotate up and down in a short cycle around the support shaft 35 to float the selected fish F from above the conveyor belt 34. The drive roller 32 is connected to an electric motor 37 via a belt 38, and rotates at a constant speed. The conveyor belt 34 is made of a polyester net or a stainless steel plate having a large number of small holes.

As shown in FIG. 1, the air passage D has a substantially triangular shape whose cross-sectional area increases toward the upstream side of the belt conveyor 30, that is, downward, as shown in FIG. A sorting nozzle 16 for ejecting air to separate and sort small fish from the sorted fish F is provided, and a nozzle 17 for flipping upward is also provided on the lower surface of the conveyor belt 34. The sorting nozzle 16 and the flip-up nozzle 17 are connected to a blower through an air duct (not shown), and the air duct is provided with an electric heater and other means for heating and drying the air. ing.

Thus, the air blown out from the flip-up nozzle 17 acts on the lower surface of the selected fish F through the conveyor belt 34, and the selected fish F is conveyed to the conveyor belt by utilizing the fact that the belt conveyor 30 is turned from ascending to descending. It jumps up from the surface of 34 and floats. The jumped-up selected fish F is blown toward the downstream side of the conveyor belt 34 by the air blown out from the sorting nozzle 16,
Again, it falls onto the conveyor belt 34. Since the compressed air blown out from the sorting nozzle 16 is expanded in the air passage D in the blowing direction, the compressed air expands and the speed is rapidly reduced, so that the sorted fish F does not fly too far. ing. In addition, the weight of the shirasu passing through the flip-up nozzle 17 is set by increasing or decreasing the air volume of the air blown out from the sorting nozzle 16 or the electric power input to the vibrator 36. .

In the vicinity of the driven roller 33 of the belt conveyor 30, transport nozzles 18, 19 and an electrostatic device 40 are provided. The conveying nozzles 18 and 19 are connected to the conveyor belt 3
4 open obliquely upward from the lower surface. Therefore,
Air is blown from below toward the selected fish F that has dropped from the supply conveyor 12 onto the conveyor belt 34, and among the selected fish F blown off by the action of the selection nozzle 16,
The fish that has been blown to a distant place, that is, the small fish is further blown off sequentially toward the stopper plate 13 and dropped into the small fish receiving box 14.

The electrostatic device 40 is a device in which electrodes of an electric dust collector are diverted. Specifically, the electrostatic device 40 includes a positive electrode 41 and a negative electrode 42 each composed of ten stainless steel wires, and they sandwich a conveyor belt. And a high voltage of about 50,000 volts can be applied. Thereby, the conveyor belt 3
The selected fish F on 4 is negatively charged and sucked by the positive electrode 41, cooperating with the vibration of the belt conveyor 30 by the vibrator 36 and the action of the flip-up nozzle 18,
Float from the conveyor belt 34. Reference numeral 43 denotes a high-voltage power supply for the electrostatic device 40, which is connected to the electric wire-shaped positive electrode 41 while being insulated by two insulators 44, 44. Numeral 45 is a drying nozzle for injecting air toward the insulator 44.

Reference numeral 13 denotes a stopper plate provided near the start end of the belt conveyor 30. A small fish receiving box 14 is placed below the stopper plate 13, and small shrimp, small crabs, planktons, or shirasu are lost. Are excluded from the selected fish F and thrown. 15 is a belt conveyor 30
This is a litter box for receiving product slack placed below the end of the product.

In this manner, the selected fish F jumped up from the surface of the conveyor belt 34 is blown toward the downstream side of the conveyor belt 34 by the air blown out from the selection nozzle 16, and is thin and wide in the width direction of the belt 34. At the same time, the fish that has been scattered and blown away, that is, the lightweight small fish is blown off toward the stopper plate 13 and dropped into the small fish receiving box 14.

FIG. 3 is a flow chart showing a process from landing of whitebait to shipping. In other words, whitebait landed from a boat is put into a kettle and boiled. Boiled whitebait is fried in a kettle and classified by market. For example, Kanto Market A
And Kansai Market B. Those destined for the Kanto market A are then sent to the sorting process, and those destined for the Kansai market B are dried in the sun for about half a day and then sent to the sorting process to maintain the predetermined quality, And separated into
The former is packaged and shipped to the food market, and the latter is boxed and shipped to the feed market.

Next, the selected fish F in the above embodiment is selected.
Will be described. First, when the wind selection device 10 starts operating, it is vibrated by the vibrator 36, and the belt conveyor 30 vibrates up and down by a small angle about the support shaft 35 as an axis. This cycle is about 50 or 60 Hertz, which is the same as the frequency of the power supply. Next, the selected fish F fried in the kettle or dried for about half a day is continuously supplied onto the conveyor belt 34 by the supply conveyor 12. The supplied selected fish F is biased toward the center on the conveyor belt 34, but is dispersed right and left by the vibration of the conveyor 30 and the air from the conveying nozzles 18 and 19 blown up from below. It is transported diagonally upward.

When the selected fish F reaches just above the flip-up nozzle 17, the air blown up from the nozzle 17 and the conveyor 3
By the action of up and down movement by 0, it is jumped up from the surface of the conveyor belt 34 and lifts up by about 5 to 15 cm. Air is blown from the sorting nozzle 16 there, and the sorted fish F is blown off toward the upstream side (lower side) of the conveyor 30. The relatively light ones are blown away, and the heavy ones are blown close and again the conveyor belt. Fall to 34. While this process is repeated several times, the object that has fallen close to the container 15 passes through the sorting nozzle 16 and falls into the receiving box 15 for shirasu.
Although shrimp and small crab containing water fall relatively close at first, when they are blown off by the sorting nozzle 16,
Separates the water contained inside, so that it will then be blown away.

Among the selected fish F, some of the fish F that have been blown away are those that go up to the position of the flip-up nozzle 17 again, and the rest are the transport nozzles 18 and 19 that open downward.
As a result, it is blown downward, hits the stopper plate 13, falls downward, and falls into the small fish receiving box 14.

In the above description, the scope of the present invention is not limited by the type of small fish described as "whitebait" but refers to the whole small fish used as a raw material for so-called "boiled and dried". Things.
