DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a boiled bean boiler and the like, which are used in the production of boiled beans and in the process of producing sweetened chestnuts in the processed food industry.

[0002]

2. Description of the Related Art Conventionally, in the production of this type of boiled beans, on a small scale, raw materials are put in a double pot with a steam jacket, and on a medium scale, a basket filled with the raw materials in the double pot is used. Some are loaded. Also, on a large scale, a heating tube (indirect heating) or a steam blowing tube (direct heating) is installed at the bottom, and a basket is loaded. They are all stationary and not circulating.

[0003]

In the case of the stationary type, it is very difficult to obtain a uniform temperature in the tank because the heating intensity is proportional to the amount of circulation of hot water (natural circulation). For example, when the water boiling temperature reaches about 95 ° C., the amount of the heated steam becomes very small, so that the circulation in the tank is almost stopped. . As a result, uneven boiling occurs.

[0004] Further, when the temperature is rapidly increased, steam bubbles are immediately generated from the heat transfer surface and serve to crush the beans by mechanical force when passing through the beans in the basket. As a result, product loss increases.

Further, in the case of the stationary type, the accommodating at the time of boiling with water is performed by taking an accommodating floating on the surface with a ladle, or after boiling, supplying water from below to overflow the entire tank. These operations are extremely problematic in that they require labor, energy loss, and deterioration of the workplace environment.

[0006] The present invention has been proposed in view of these problems, and its object is to eliminate boiling unevenness, eliminate breakage loss of products such as beans, and to remove water during boiling. And to provide a boiled apparatus for boiled beans and the like, which can perform rationally.

[Means for Solving the Problems]

In order to achieve the above object, the present invention is to form a plurality of boiled chambers for accommodating a liquid-permeable basket for loading an object, and to form an excess on one or both sides of each boiled chamber. A tank having a plurality of partition plates forming a gutter-like passage for overflowing water; and Or a bubble blowing nozzle for injecting air or the like to blow bubbles to the downstream side, and installed at the upper part of the downstream side of the gutter-shaped passage, and the bubbles blown to the downstream side by the bubble blowing nozzle are out of the tank. A means for discharging foam, a circulating water pipe drawn out from the lower portion of the downstream side of the gutter-shaped passage and returned to the bottom of each boiler chamber, a circulating pump installed in the middle of the circulating water pipe, and a circulating pump. The water installed in the middle of the water pipe Water in the tank is drawn out from the lower part of the gutter-shaped passage by the circulation pump, heated by a heater, and refluxed from the bottom of each boiler into the tank to continuously circulate the water. The object in each boiled room is heated by the heated circulating water, and the ac generated from the object by the heating is caused to overflow together with surplus water into a gutter-shaped passage partitioned by the partition plate, and the gutter-shaped gutter is formed. In the passage, the foam is blown out of the tank by the foam blowing nozzle and the foam discharging means.

A plurality of triangular weirs are formed on the upper surface of each partition plate at appropriate intervals. Also, the bottom of the gutter-like passage between the two partition plates is inclined so as to become lower from upstream to downstream. The heater is constituted by a steam blowing pipe for blowing steam into circulating water. In addition, a circulating water dispersing member such as a punching metal is provided at the circulating water reflux port. A nozzle for spraying washing water is installed above the gutter-like passage between the two partition plates. Further, the circulation water return port is divided into a plurality of sections for each boiling chamber.

[0009]

By circulating a constant amount of hot water by a circulation pump and a circulation water pipe during boiling, uniform temperature can be achieved in the entire area of the tank, and uneven boiling can be eliminated. The circulating water return port is located at the bottom of each boiler room, and the circulating water return port is divided into a plurality of portions for each boiler room.

[0010] Further, since the heater is installed in the middle of the circulating water pipe and the heating source is taken out of the tank, steam bubbles are not directly generated in the tank, and the object caused by the mechanical force of the steam bubbles is not generated. It is possible to prevent damage to things (beans and the like). Since a circulating water dispersing member such as a punching metal is provided at the circulating water reflux port, the above-described operation is improved.

[0011] By dividing the inside of the tank with a plurality of partition plates,
Because a plurality of boiled rooms for accommodating the liquid-permeable basket for loading the object are formed, and a gutter-like passage for overflowing surplus water on one or both sides of each boiled room is formed. Then, the water floating on the free surface of the hot water overflows from the upper surface of each boiler chamber together with surplus water to the gutter-like passage, and bubbles are blown from the upstream to the downstream of the gutter-like passage by the bubble blowing nozzle. The water can be discharged out of the tank via the foam discharging means, and the intake during water boiling can be automatically and rationally performed. Also, since a plurality of triangular weirs are formed at appropriate intervals on the upper surface of each partition plate forming the gutter-like passage, overflow of excess water is dispersed from each boiler chamber to the gutter-like passage on average. Therefore, it is possible to prevent the accumulator from accumulating in one place, and to ensure that the accelerating operation is performed smoothly and reliably. By configuring the heater with a steam injection pipe, the circulating water will be directly heated, and in this case, the amount of hot water will naturally increase,
The access by overflow is more rational. In addition, when it is necessary to leave a certain amount of soluble solids in hot water, the residual amount of soluble solids in hot water can be adjusted by adjusting the injection amount of the bubble blowing nozzle. .
