Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a grain processing device for steaming rice, red beans, etc.

(Prior art) The conventionally known Japanese Patent Application Laid-Open No. 59-22527 discloses an endless belt having a large number of ventilation holes for conveying grains, as a prior art of the invention of Japanese Patent Application No. 131715-1980. A plurality of steam chambers are rotatably provided and opened in a space formed between an ascending part for grain conveyance and a descending part of the endless belt with the ascending part side facing upward, and are arranged in parallel in the conveying direction of the endless belt. Each steam chamber is provided with a steam exhaust nozzle that protrudes upward, the steam exhaust nozzle is connected to a steam pipe in the front and rear direction that penetrates each steam chamber, and a chevron-shaped guide body is provided above the steam exhaust nozzle. The structure provided is described.

(Problems to be Solved by the Invention) Since the above-mentioned known example is described as prior art, its specific structure is not disclosed at all.

However, since the above-mentioned known example has a structure in which a chevron-shaped guide body is provided at the top of the steam exhaust nozzle that protrudes upward into each steam chamber, the steam ejected upward once collides with the guide body and then is guided. As a result, the force of the eruption is inhibited and the spread of steam is poor. Further, while steam tends to be trapped in the upper half of the steam chamber, the lower half has a lower indoor temperature than the upper half and is more easily affected by the outside temperature, so the steam temperature also tends to drop. Therefore, steam unevenness tends to occur in the rice transported by the net conveyor.

(Means for Solving the Problem) Therefore, the present invention rotatably provides an endless belt 1 having a large number of ventilation holes for transporting grains, and connects an ascending part A for transporting grains and a descending part A of the endless belt 1. A steam chamber 2 opened with the ascending section A side as the upper surface is provided in a space formed between the upper and lower parts B, and a discharge nozzle 1 for discharging steam downward is provided at an intermediate portion in the vertical direction within the steam chamber 2.
4 and intersecting the conveyance direction of the endless belt 1, the steam pipe 15 is open at least at the bottom, and the lower end is located closer to the bottom wall of the steam chamber 2 than the discharge nozzle 14. This grain processing apparatus is characterized in that the grain processing apparatus is surrounded by a steam guide body 17.

(Example) An example of the present invention will be described with reference to the drawings.
is a grain processing device, and on the top of the frame 5,
A primary steaming device 6, a conveyor 7, an immersion device 8 storing high-temperature water of approximately 85°C, a secondary steaming device 9, etc. are provided, and at the bottom of the frame 5, a motor 10, which is a power source for the drive unit, and a high-temperature water Motor 1, which is the source of
0. A hot water regulator 11 that is a source of high-temperature water; a steam regulator 12 that can purify the high-temperature steam sent from the boiler and that can be equipped with a pressure regulator and send it to each steam supply section; etc.

The secondary steaming device 9 includes an endless belt 1 on which grains sent by the conveying device 13 of the soaking device 8 can be placed and conveyed, and a steam chamber 2. The endless belt 1 is provided with a large number of ventilation holes capable of preventing grains from falling, and is rotatably provided.

A plurality of steam chambers 2 are arranged in a row in the moving direction of the endless belt 1 in a space formed between the grain conveying upper and trailing parts A and the descending parts B of the endless belt 1.

Further, the steam chamber 2 is formed into a box shape with an open top surface, and is provided with approximately the same width as the width in the transverse direction with respect to the grain conveyance direction. The upper surface of each of the steam chambers 2 is brought into contact with or close to the lower surface of the ascending portion A for grain conveyance of the endless belt 1, and a temperature of about 100° C. to 115° C. is maintained in the room toward the bottom wall 3. A steam pipe 15 is provided in which a plurality of discharge nozzles 14 capable of discharging high-temperature steam are provided at predetermined intervals in the width direction. Further, on the outer surface side of the bottom wall 3 of the steam chamber 2, a steam passage 16 is provided that can guide steam having a higher temperature than the steam supplied into the steam chamber 2, for example, 120°C.

Further, in the steam chamber 2, the steam pipe 15 is provided with a lower end close to the bottom wall 3 and an upper part formed in a mountain shape.
A steam guide body 17 surrounding the steam guide body 17 is provided. Then, both left and right end portions of the steam guide body 17 are fixedly attached to the left and right side walls 18 of the steam chamber 2.

Reference numeral 19 denotes a crusher provided above the conveyance start end of the endless belt 1, and is configured to rotate in the direction of the arrow so that the grains that have been soaked by the soaking device 8 are piled up gently in the conveyance direction. 20 is a cover.

(Operation) Next, the operation will be explained. The grains are exposed to high temperature steam in the primary steamer 6 and sent to the soaking device 8 by the conveyor 7, and are transported to the secondary steamer 9 side by the transport device 13 while absorbing water. The grains fed onto the endless belt 1 from the end of the soaking device 8 are transported toward the end of the transport, but during transport, they are pushed toward the transport direction by the crusher 19 and become soft. It becomes a state of high accumulation.

In addition, the high temperature steam discharged downward from the discharge nozzle 14 of the steam pipe 15 fills the steam guide 17 and diffuses, and is further guided toward the bottom wall 3 side by the steam guide 17 and dispersed back and forth. After being heated by the bottom wall 3 heated by the high temperature steam supplied into the steam passage 16, it rises.

Most of the heated steam passes through the ventilation holes of the endless belt 1 and between the grains piled up high, and the grains are steamed by being exposed to this steam.

In this case, since the discharge nozzle 14 discharges steam downward, the steam is ejected downward vigorously, and the ejected steam is guided by the steam guide body 17, so that the steam is well dispersed in the left and right directions, and the steam chamber 2 Distributed throughout.

In addition, the bottom wall 3 of the steam chamber 2 is heated by the steam ejected from the discharge nozzle 14, and the other end of the steam chamber 2 is heated by the steam supplied into the steam chamber, so the steam chamber 2 is kept warm. It can also be expected to have the effect of stabilizing the steam temperature.

Therefore, the grains to be transported are exposed to stable steam which is dispersed throughout the steam chamber 2 and increases in temperature, so that high-quality steamed grains with little variation in steaming can be obtained.

(Effects) Since the steam ejected into the steam chamber 2 is first guided toward the bottom wall 3 side, dispersion within the steam chamber 2 can be improved. Therefore, the steam chamber 2 can be used effectively and the steaming efficiency of grains can be improved. Further, the ejected steam heats the bottom wall 3 of the steam chamber 2, and the other walls of the steam chamber 2 are heated by this steam. Therefore,
Since the steam chamber 2 can be kept warm and the steam temperature can be stabilized, variations in the quality of the food to be steamed can also be reduced.
