Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a continuous steamer for small fish that enables salting and heat treatment of small fish without loss of nutrients or collapse of structure or shape.

Unlike large fish, it is difficult to cook individual small fish such as chilimen, kounago, and dashijiko, so a large number of small fish are supplied to the market as whole after being subjected to prescribed processing. In processing, salting and heat treatment are often carried out in order to sterilize the raw fish, heat denature the fish protein to make it suitable for consumption, obtain storage stability with salt, seasoning to suit the tastes of consumers, etc.

Conventionally, such salting and heat treatment was carried out by filling a large-capacity boiling pot with salt water of a predetermined concentration and boiling it, and boiling the raw fish in the salt water to ripen it, making continuous processing of the raw fish impossible. This requires a large amount of water for processing, and a huge amount of heat is required to boil a large amount of water with a high specific heat. This results in products such as dashi crackers with low nutritional value, and the convection impact of boiling water causes the surface structure of the raw fish to collapse and become crackly, making the subsequent drying process difficult and reducing the product value in terms of appearance. It had disadvantages such as causing the price to drop.

In view of the above-mentioned drawbacks, the present invention interposes a net-like conveyor between the cleaning process and the drying process of raw fish, and during the process of the conveyor, a draining device and a shower for spraying concentrated salt water are sequentially installed, and the conveyor is installed at the rear of the shower. A continuous steamer for small fish, comprising a large number of heat dissipation pipes formed in close proximity to each other above and below to form a heating chamber that surrounds the heat dissipation pipes and the conveyor in the form of a tunnel, and a net-like conveyor provided between the cleaning process and the drying process of raw fish. It is an object of the present invention to solve the above-mentioned drawbacks by providing a continuous steamer for small fish, in which the conveyor passes slightly below the water surface of a salt water tank containing salt water of a predetermined concentration and equipped with a salt water heating device. An embodiment of the present invention will be described below based on the drawings. Reference numeral 1 denotes a conveyor of a predetermined width (for example, 1 m) suspended endlessly between rotating bodies 2 and 2'; The net is made of a rust-proof material such as stainless steel and has a mesh that prevents small fish from falling off. The rear end of the conveyor 1 is slanted into a stirring tank 4 containing stirring water via rollers 3, 3'. 5 is a stirring shower that stirs the stirring water contained in the stirring tank 4, and 6 is formed adjacent to the stirring tank 4 to store small fish and transport them sequentially to the stirring tank by a conveyor (not shown) or the like. This is a cleaning tank that supplies water to the water.

Next, reference numeral 7 denotes a heating chamber consisting of upper and lower steam receiving plates 8 and 9, which is formed so as to surround the forward travel section of the conveyor 1 in the form of a tunnel. The portion 11 is formed to have a width as narrow as possible so that the conveyor 1 and the raw material fish placed on the conveyor 1 can barely pass through.

Reference numerals 12, 12', . . . designate a large number of heat dissipation tubes formed at positions close to the top and bottom of the conveyor 1 passing inside the heating chamber 7. The upper steam receiving plate 8 includes a plurality of divided receiving plates 8a, 8b, 8c, .
It may be formed separately. In addition, 13 is the heating chamber 7
It is a roof that covers the entire upper part.

On the other hand, reference numeral 14 denotes a draining device that is provided facing the conveyor 1 at a portion where the forward stroke portion of the conveyor 1 appears above the water surface of the stirring tank 4;
Although the details of 4 are not shown in the drawings, a suction box that acts as a suction and an air blower that blows out air are formed adjacent to each other directly below the conveyor 1, and the former absorbs the moisture attached to the raw fish and drains it, and the suction box acts as a suction box. The raw material fish strongly stuck to the conveyor 1 is blown up and stirred by the latter.

Next, 15 is a shower installed above the conveyor 1 between the draining device 14 and the heating chamber 7, and the shower 15 is configured to spray concentrated salt water of a predetermined concentration onto the conveyor 1. The shower 15 is connected to a recovery device (not shown) for the concentrated salt water that has passed through the conveyor 1, so that the concentrated salt water can be recycled.

A blower 16' is provided at the front end of the conveyor 1 and blows air from the front end of the conveyor 1 toward an adjacent dryer (not shown).
A blower is installed directly below the conveyor 1 inside the heating chamber 7, and blows air from the back surface of the conveyor 1 toward the front surface.

Next, in the continuous steamer for small fish according to the second invention, as shown in FIG. 1 Chain bands on both sides 1
Sprocket 19,2 meshed with 8,18'
0 into a shallow saltwater tank 21. The salt water tank 21 contains salt water of a predetermined concentration, and is configured to boil the salt water with a heating device 22 of an appropriate mechanism formed outside and below the salt water tank 21, and the conveyor 1 is arranged as shown in FIG. The salt water is passed slightly below the water surface so that the raw fish placed on the conveyor 1 is barely submerged in the water surface. In addition, 23 is a cover body that covers slightly above the salt water tank 21, 24, 24', 24'', 24
are rollers that guide the conveyor 1 in a predetermined direction.

Next, to explain the operation of the continuous steamer for small fish according to the present invention, in the first invention, the raw fish supplied from the cleaning tank 6 to the stirring tank 4 is stirred and dispersed in the stirring water by the stirring shower 5. are sequentially placed on the conveyor 1, which circulates in the direction of the arrow in FIG.
transported.

After the water adhering to the raw fish is removed by the drainer 14, the raw fish is sprayed with concentrated salt water by the shower 15, and then transported through the inlet 10 into the heating chamber 7. Inside the heating chamber 7, the raw fish is heated evenly from above and below by the heat dissipation pipes 12, 12', etc., and the salted and heat-treated raw fish is transported to the outside of the heating chamber 7 through the outlet 11 and transferred to the conveyor 1. Blower 1 from the front end
It is delivered to the drying process by the spraying action in step 6.

In short, the present invention provides a continuous steamer for small fish in which a net-shaped conveyor is interposed between the cleaning process and the drying process of raw fish, and a draining device is installed during the process of the conveyor, in which concentrated salt water is introduced during the process of the net-shaped conveyor. In addition to sequentially installing showers for dispersion, blowers are installed at the front end of the conveyor and directly below the conveyor, and at the rear of the shower, a large number of heat dissipation pipes are formed near the top and bottom of the conveyor, and the heat dissipation pipes and the conveyor are connected to each other. It is made up of a heating chamber that surrounds the raw fish in the form of a tunnel, and after the raw fish is drained, it is sprayed with concentrated salt water by the shower 15, which prevents dilution of the concentrated salt water and also prevents the raw fish from being exposed to the concentrated salt water. Improves adhesion,
Furthermore, since the moisture in the concentrated salt water adhering to the raw fish is evaporated and the heating chamber 7 is filled, the raw material fish can be heated to a steaming state with such hot steam, and the concentrated concentrated salt water can penetrate into the interior of the raw raw fish. Therefore, the raw fish can receive good salting and heating effects without having to be boiled in salt water to achieve the objectives of sterilization by heating, denaturation of fish meat proteins, acquisition of storage stability by penetration of salt, and seasoning. Moreover, since steam heating is used, it is possible to prevent the flavor of the raw fish, the leaching of nutrients, and the collapse of the surface structure, etc., making drying of the raw fish in the next process extremely easy and quick. Since the heating is carried out in the heating chamber 7, the thermal efficiency is extremely high, and heating is completed with enough heat to simply evaporate the water in the concentrated salt water that adheres to the raw fish, so the amount of heat is extremely small compared to the case of boiling in salt water. All you need is water and heat.

In addition, in the present invention, blowers are provided at the front end of the conveyor 1 and directly below the conveyor 1, so that the raw fish can be stirred up in the heating chamber 7 and evenly heated. Its practical effects are enormous, such as being able to blow away the raw material fish that has stuck to the surface in a predetermined direction and completely transfer it to the drying process.
