Abstract

PURPOSE:To enable the baking of a dough in a short time without scorching the surface part by generating hot air in a mixing chamber, blowing the air to the lower part of a heating chamber and passing through a container of the dough from the bottom upward. CONSTITUTION:Hot air is generated in a mixing chamber 15' by heating the air sent with a blower with the heat of combustion generated by a gas burner 15. The hot air is sent to the lower part of a heating chamber 13. When the hot air is passed through a container 7 from the bottom upward, each particle of the dough in the container 7 containing dough is uniformly heated with the passing hot air because the dough is maintained in a sieving state. Each particle is heated also by the hot atmosphere of the heating chamber heated with the hot air to enable the baking of the dough in a short time.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a roasting machine for roasting peanuts, bean confectionery, etc., and in particular, a roasting machine for roasting confectionery bodies while sieving dough bodies. The present invention relates to improvements to roasting machines installed in various ways.

[Conventional technology]

For example, one of the methods for frying peanuts, bean sweets, etc. is to fry the dough using the combustion heat of gas while passing through a sieve, and this method has been commonly used in the past.

FIG. 5 is a drawing showing an example of the specific structure, in which a container body 7 is suspended in the main body of the roasting machine so as to be horizontally swingable, and the container body 7 is placed between the main body 1 and the main body 1. A pair of upper and lower gas burners 10.10 are arranged facing each other. While the container body 7 is horizontally oscillated, the dough body is directly roasted by the combustion heat of the gas burners 10 and 10.

[Problem to be solved by the invention]

However, in the case of a roasting machine that directly roasts the container body while horizontally rocking it as described above, it is easy to get burnt on one surface part, and it takes a long time to roast it. In this way, when the heat of gas combustion is used directly for frying, the heat is gradually transferred from the surface of the dough to the center.

In addition to the problem that the surface part is easily heated and dried, the surface part becomes easily scorched, and in order to prevent the surface part from becoming scorched, the frying temperature is relatively low ( It takes a long time to fry (approximately 170℃), and because the surface area is heated first, it becomes difficult for moisture to escape from the center area (approximately 170℃).
When roasting 0 kg of peanuts, it takes about 20 to 25 minutes), and since the surface and center cannot be heated evenly, the fibers are not broken down evenly, resulting in a soft finish. There are problems in the way it occurs.

The present invention attempts to improve the above-mentioned problems, and one object of the present invention is to achieve roasting in a short time without causing scorching on the surface in a rocking roaster. The purpose of this method is to make it possible to not only disintegrate the fibers evenly but also to make them soft to fry.The specific means and functions thereof are as follows.

[Means to solve the problem]

■ A container body is installed horizontally in a heating chamber formed inside the main body, and a gas burner is arranged on the side wall of the main body, and a hot air mixing chamber is provided in front of the gas burner, and the tip of the mixing chamber The opening is communicated with the heating chamber so as to face the lower part of the container body.

■ An intake duct is branched from the exhaust duct extending outside the main body from the top of the heating chamber, and the intake duct is connected to the suction side of the blower, and the air supply duct extends from the discharge side of the blower. The distal end portion is opened so as to face the base side of the mixing chamber.

[For production]

Combustion heat from the gas burner and air forced from the blower generate hot air in the mixing chamber, and the hot air is blown into the lower part of the heating chamber. Then, when the hot air passes from the bottom to the top of the container, the dough inside the container is in a sieving state, so each particle of the dough is uniformly heated by the hot air passing through it, and the dough is heated evenly by the hot air. Each particle is also heated by the high ambient temperature of the heating chamber, thereby achieving the effect of frying the dough in a short time.

Furthermore, by connecting the intake duct branching from the exhaust duct to the suction side of the blower, it is possible to increase the air temperature of the blower using waste heat.

In a state where the bottom plate portion 7b... is set horizontally.

When the disc bodies 3, 3 are horizontally rotated through the rotational drive of the motor 4, the support frame 5, whose front end portions are pivotally connected to the eccentric position of the disc bodies 3, 3, horizontally swings. Through the horizontal swinging, a state in which the container body 7 similarly swings horizontally is obtained.

In this state where the container body 7 horizontally swings,
When an appropriate amount of dough is introduced into the container body 7 through the opening and closing operation of the input port 8, a state is obtained in which the dough material is sieved through the horizontal swinging of the container body 7. Also, around this time, the gas burner 15 is ignited, and the blower 18 is ignited.
By driving the gas burner 15, the air heated by the combustion flame of the gas burner 15 is turned into hot air, which is sent through the opening at the end of the mixing chamber 15' to the heating chamber 1 through the blowing action of the blower 18.
This hot air is blown into the container body 7 to fry the dough inside the container body 7. More specifically, the hot air blown into the lower part of the container body 7 passes from the lower part of the container body 7 upwards, and during this time, as described above, it passes between each particle of the dough body that is sifting inside the container body 7, and the same air is blown into the lower part of the container body 7. In addition to uniformly heating the particles, the heating chamber 13 is heated to a high ambient temperature by hot air, and each particle is heated as a whole by this ambient temperature, so that the fibers of the fabric are uniformly decomposed in a short time.

An intake duct is branched from the exhaust duct, and the intake duct is communicated with the suction side of the blower, and the tip of the air supply duct extending from the discharge side of the blower faces the base side of the mixing chamber. By opening the opening, the hot air blown from the mixing chamber into the heating chamber can evenly and uniformly heat each particle of the dough being sieved, thereby preventing scorching on the surface of the dough. In addition to being able to roast in a short time without any problems, the fibers can be broken down evenly and the roasting can be done softly.

In addition, as mentioned above, the intake duct that branches from the exhaust duct is connected to the suction side of the blower, and the waste heat is used to increase the temperature of the blower's air. Coupled with the fact that it can be roasted in the oven, it has become possible to significantly increase its thermal efficiency.
