Description

DETAILED DESCRIPTION OF THE INVENTION (Objective of the Invention) The present invention relates to a steaming pot for grains, and its purpose is to uniformly and efficiently steam grains while keeping them in granular form.

(Prior Art) Conventionally, in steaming pots for barley, which is a raw material for shochu, raw barley is piled up in a mountain shape in a vertical tank, and steam is injected into the tank for steaming.

In this steamer, the barley piled up in the tank was steamed in a stationary state, resulting in poor steam passage, extremely low steaming efficiency, and wasted energy.

Furthermore, when the barley is steamed in the tank and swells, it becomes a lump of barley, which is difficult to discharge from the tank after steaming, and often causes inconvenience in transferring to the next process.

(Structure of the Invention) The present invention provides a drum that is rotatable around a horizontal axis and has a raw material input port and a raw material discharge port on its circumferential surface, and a ribbon screw is provided on the inner circumferential surface of the drum. A steam chamber (jacket) connected to a steam source is provided in the drum, and steam is ejected from the steam chamber into the drum to steam the raw material grains.Examples will be described below with reference to the drawings.

In FIGS. 1 to 4, a drum 1 for storing grains as a raw material has a shaft 2 inserted through and fixed to its axial center, and raw material input ports 3 are provided with openings at several locations on the circumferential surface.

The raw material inlet 3 is closed with a net-like inlet lid 5 having a large number of through holes 4 large enough to prevent raw materials from easily passing through.

This input port cover 5 is provided to be openable and closable, and in the one shown in the figure, one edge is attached to the outer peripheral surface of the drum 1 with a hinge 6, and the other edge is hooked with a stopper 7.

In the center of the drum 1, raw material discharge ports 8 are provided at several locations in the circumferential direction. Obstructed.

The raw material discharge port 8 can be opened and closed by sliding the discharge port cover 10 in the circumferential direction.

A ribbon screw 11 is fixed to the inner peripheral surface of the drum 1 in a spiral manner.

The ribbon screw 11 is not continuous from one end of the drum 1 to the other, and the left and right halves of the drum 1 have different helical winding directions and correspond to the rotational direction of the drum 1. The drum 1 is provided so that the raw grain moves to the center of the drum 1 as the drum 1 rotates.

The ribbon screw 11 has a hollow steam chamber 12 (jacket) in a portion located on the opposite side from the raw material input port 3.
are formed, and a large number of steam jet ports 13 are arranged in stages toward the end surface of the drum 1, so that steam can be jetted into the drum 1 from the steam jet ports 13.

In the drum 1, a steam pipe 14 is provided adjacent to the steam chamber 12.
The steam pipe 14 and the steam chamber 12 are connected to each other.

The right end of the steam pipe 14 in FIG.
connected to.

The lower ram 1 is arranged horizontally, and both ends of the shaft 2 are supported by bearings 16 provided on a frame 15.

The left end of the shaft 2 is formed hollow as described above, and the hollow part 2
A steam supply pipe 17 is airtightly connected to a.

Although the shaft 2 rotates together with the drum 1, the steam supply pipe 17 does not rotate and is supported by the pedestal 15.

A sprocket 18 is fixed to the right end of the shaft 2 and is connected to a sprocket 20 of the drive device 19 by a chain 721.

An annular guide 23 is provided on the pedestal 22 over almost the entire circumference of the drum 1 so as to surround the raw material discharge port 8 of the drum 1.

Although this guide 23 is fixed to the pedestal 22, it does not hinder the rotation of the drum 1.

An opening 24 is provided in a part of the front side of the guide 23, and the opening 24 is normally closed with a lid 25.

One edge of the lid 25 is fixed to the guide 23 with a hinge 26, and the other edge is fixed to the guide 23 with a stopper 27.

The lower part of the guide 23 is opened to form a discharge port 28,
A belt conveyor or the like is provided below the discharge port 28, so that the raw material falling from the discharge port 2B can be transferred to the next process.

An air pipe 29 is connected to the back side of the guide 23 so that warm air inside the drum 1 can be exhausted to cool the raw material.

An exhaust fan is connected to the air pipe 29.

(Operation of the invention) In order to steam grains using the apparatus of the present invention, the raw material input port 3 of the drum 1 is directed upward, the input port cover 5 is opened, and half of the total volume of the raw material grains is poured into the tank 1. do.

Next, the input port cover 5 is closed, the drum 1 is rotated, and water is jetted into the drum 1 from the steam supply pipe 17 through the steam outlet 13 of the ribbon screw 11 to wash the grains.

After washing with water, the rotation of the drum 1 is stopped with the raw material input port 3 facing downward, and then steam is jetted into the tank 1, and the water remaining in the tank 1 is sufficiently discharged by the pressure.

When steam starts to come out from the through hole 4 of the charging lid 5,
Rotate drum 1 again.

The grains are steamed while being stirred in the drum 1.

After steaming has been carried out for a predetermined period of time, the ejection of steam is stopped, and then the steamed grains are cooled.

Cooling is performed while the drum 1 is rotating. When the blower is operated while the drum 1 is rotating, outside air is sucked into the drum 1 through the through hole 4 of the input port cover 5 and the through hole 9 of the discharge port cover 10, thereby cooling the grains.

Although it is possible to cool the grains by sending cold air into the drum 1, a suction method is preferable since there is a risk that water droplets in the drum 1 may scatter to the outside.

After cooling is completed, the rotation of the drum is temporarily stopped, the lid 25 of the guide 23 is opened, the raw material discharge port 8 of the drum 1 is opened, and the lid 25 is closed again.

Next, when the drum 1 is rotated again, the grains in the drum 1 are gradually transferred to the center of the drum 1 by the ribbon screw 11 as the drum 1 rotates, and are discharged from the raw material outlet 8 into the guide 23. It falls inside and is discharged from the opening 28.

(Effects of the Invention) Since the present invention has the above configuration, it has the following advantages.

(1) Once the grains as raw materials are put into the tank, the process of washing, steaming, and cooling and discharging the grains can be carried out efficiently and easily without the need for troublesome operations.

(2) Since steaming is performed while the drum is rotating, the grains are stirred during steaming and do not form lumps in the drum.

Therefore, there is no problem in discharging the grains and transporting them to the next process.
