Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a steamer used for defrosting frozen foods, etc.

(Prior art) A steamer is conventionally equipped with a boiler tank that is heated from below by a gas burner, and a nozzle is provided on the top wall of the boiler tank to release the steam in the boiler tank, and this nozzle is covered from above. There is one in which a bamboo steamer is placed on the ceiling wall.

(Problem that the invention aims to solve) However, conventional steamers simply steam the material to be steamed using the steam generated in the boiler tank, and this steam is below 100℃ and contains a large amount of moisture. When a steamer is used to thaw frozen foods, there is a problem in that thawing takes a long time and the frozen foods contain a lot of water, which impairs the original characteristics and taste of the frozen foods.

SUMMARY OF THE INVENTION In view of the above-mentioned problems, it is an object of the present invention to provide a steamer that can defrost frozen food well and quickly without impairing the characteristics and taste of the food.

(Means for Solving the Problem) The technical means of the present invention for solving this technical problem includes a boiler tank 1 heated from below by a gas burner 2, and above the boiler tank 1.
A steam heating tank 15 is provided to be heated by the exhaust gas of the gas burner 2, and a suction port is provided in the bottom wall 15a of the steam heating tank 15 for sucking steam from the boiler tank 1 through a pressure valve 23. 1
6 is provided, and a nozzle 18 is provided on the top wall 15b of the steam heating tank 15 to release the steam in the steam heating tank 15.
Inside, a baffle plate 25 is provided to block the space between the suction port 16 and the nozzle 18 so that the steam sucked from the suction port 16 bypasses the inside of the steam heating tank 15 and is discharged from the nozzle 18. .

(Function) When the temperature inside the boiler tank 1 exceeds 100°C, the steam is sent into the steam heating tank 15 from the suction port 16 via the pressure valve 23, and the steam that has entered the steam heating tank 15 is blocked by the baffle plate 25. The vapor is then detoured through the tank 15 in the direction of the arrow, and during this detour, it is heated by the exhaust gas from the gas burner 2 and becomes dry steam at a temperature of 100° C. or higher, which is discharged from the nozzle 18. Therefore, when putting frozen food into the steamer 34 and thawing it, the frozen food can be thawed quickly with dry steam of 100°C or higher, and in this case, the frozen food does not contain much moisture. , without impairing the characteristics or taste of the food.

Further, by the action of the pressure valve 23, steam can be released from the nozzle 18 at a higher pressure, and as a result, the steam can be passed through the frozen food under pressure, and from this point of view as well, there is an effect that the food can be thawed more quickly. play.

(Example) Hereinafter, the present invention will be described according to an illustrated example. Reference numeral 1 denotes a boiler tank, which is heated from below by a gas burner 2 and is configured to discharge steam from a discharge port 3 at the upper end. There is.

A hot water tank 5 has a front wall 5a, a rear wall 5b, a left wall 5c, and a right wall 5d, and is formed into a rectangular tube shape surrounding the boiler tank 1. Water is intermittently supplied into the hot water tank 5 through a water supply pipe 6, and the water in the hot water tank 5 is supplied to the gas burner 2.
It is now heated to high temperatures by 7
is a water supply pipe that communicates with the upper end of the hot water tank 5 and the lower end of the boiler tank 1, and when water is supplied into the hot water tank 5 through the water supply pipe 6, high pressure is created in the hot water tank 5, and the hot water tank 5 is heated. The high temperature hot water in the upper part of the boiler tank 5 is sent into the boiler tank 1 via a check valve 8 and a pressure reducing valve 9. 10 is a joint provided in the middle of the hot water pipe 6. Reference numeral 11 denotes a recess provided in the front wall 5a of the hot water tank 5, through which the gas burner 2 is inserted below the boiler tank 1.

A steam heating tank 15 is provided above the boiler tank 1 so as to be heated by the exhaust gas from the gas burner 2. A suction port 16 is provided at the center of the bottom wall 15a of the steam heating tank 15, a discharge port 17 is provided at the center of the top wall 15b, and a nozzle 18 is detachably provided at the discharge port 17. Note that this nozzle 18 has a plurality of steam release holes 19 formed radially in the horizontal direction, but the nozzle 18 is replaceable and can be changed depending on the type of material to be steamed by the steam or the frozen food to be thawed. Depending on the type, for example, the nozzle can be replaced with a nozzle having a steam discharge hole 19 at the upper end, or a nozzle with another shape or structure.

The discharge port 3 of the boiler tank 1 and the suction port 16 of the steam heating tank 15 are connected to a connecting pipe 21 via a joint 22, and the joint 22 includes:
A pressure valve 23 is interposed so that steam at a temperature higher than 100° C. is sent from the boiler tank 1 into the steam heating tank 15.

Reference numeral 25 denotes a rectangular baffle plate provided in the steam heating tank 15, which connects the bottom wall 15a via four leg pieces 26.
The baffle plate 25 is placed horizontally so as to close the gap between the suction port 16, the discharge port 17, and the nozzle 18, thereby directing the steam drawn from the suction port 16 to the outer periphery of the steam heating tank 15. During this detour, the steam is efficiently heated by the exhaust gas of the gas burner 2, and the steam temperature is increased to 100%.
The temperature is raised or maintained above ℃, and the temperature is kept in a dry state that does not contain moisture. Therefore, the nozzle 18 emits steam at a temperature of 100° C. or higher and in a dry state.

Reference numeral 29 denotes an exhaust pipe, which is configured to suck exhaust gas from the gas burner 2 through a recess 30 provided in the rear wall portion 5b of the hot water tank 5 and discharge it upward. 3
1 is a water meter provided on the front wall 5a of the hot water tank 5;
32 is a drain pipe provided in the boiler tank 1.

Numeral 34 is a steamer placed in multiple stages on the top wall 15b, and each steamer 34 has a rectangular cylinder 35 and a bamboo basket 36 horizontally arranged at the bottom of the cylinder 35.
It consists of: The lower steamer 34 is the nozzle 18
It is placed on the ceiling wall 15b so as to cover it from above. Reference numeral 37 denotes an upper lid which detachably closes the upper end opening of the upper steamer 34.

(Effects of the Invention) According to the present invention, steam emitted from the boiler tank 1 can be effectively heated to a temperature of 100° C. or higher and dry using the exhaust gas of the gas burner 2, and then released from the nozzle 18. Therefore, this steam can quickly thaw frozen food, and it can thaw well without the frozen food containing moisture and impairing its characteristics and taste, and its practical effects are significant. .
