Description

TECHNICAL FIELD The present invention relates to a grain processing apparatus.

(Prior Art) In the conventionally known Japanese Patent Application Laid-Open No. 62-11419, in a grain processing apparatus including a primary steaming step, a water immersion step, and a secondary steaming step, the secondary steaming step is highly breathable. Between the ascending part and the descending part of the lateral transport endless belt formed of a material, a steam chamber having a back surface of the ascending part as an upper surface is formed, and in the steam chamber, a front-back direction parallel to the moving direction of the endless band is formed. A structure is described in which a steam pipe is provided, steam ejection holes are formed at predetermined intervals in the steam pipe, and a steam supply pipe is connected to each of the steam pipes.

Is formed, the steam chamber is provided with a steam pipe in a direction intersecting with the moving direction of the endless zone, steam discharge holes are formed at predetermined intervals in the steam pipe, and on one side of the steam pipe, The description is given of the configuration in which the steam supply pipes are connected to each other.

(Problems to be Solved by the Invention) Among the above-mentioned known examples, the former steam pipe cannot be increased so much when the width of the lateral endless belt is increased, because a difference in steam pressure spouting from each steam ejection hole is likely to occur. However, there is a limit to the efficiency, and there is a risk that steaming will be possible.

As shown in FIG. 2, the latter steam pipe has a structure in which a steam supply pipe is connected to one side of the steam pipe, so that there is a difference in temperature between the base and the tip, which may cause steaming. Similarly, if the lateral width of the endless belt for lateral feeding is increased, steaming can be further performed, so that the lateral width cannot be increased so much, and the efficiency is limited.

Therefore, the present invention, even if the length of the steam pipe is longer than a certain length, prevents the difference between the temperatures of the steam on the front side and the base side, and thus increases the lateral width of the lateral endless belt to increase the efficiency. It is designed to be raised.

However, there is a risk that the team will be steamed. As shown in FIG. 2, the latter steam pipe has a structure in which a steam supply pipe is connected to one side of the steam pipe, so that there is a difference in temperature between the base and the tip, which may cause steaming. Similarly, if the lateral width of the endless belt for lateral feeding is increased, steaming can be further performed, so that the lateral width cannot be increased so much, and the efficiency is limited.

However, the present invention provides a grain processing apparatus including a primary steaming step A, a water immersion step B, and a secondary steaming step C, wherein the secondary steaming step C is a laterally-feeding endless belt 1 formed of a material having high air permeability. Between the ascending part a and the descending part b, a steam chamber 2 whose upper surface is the back surface of the ascending part a is formed, and the steam chamber 2 intersects with the moving direction of the endless belt 1 and Is provided with a steam pipe 4 in the left-right direction longer than the left-right width of the steam pipe 4, steam discharge holes 3 are formed at predetermined intervals in the steam pipe 4, and steam supply pipes 4'are provided on both left and right sides of the steam pipe 4. Since the grain processing device is configured to be connected and steam can be supplied from both the left and right sides, a. The secondary steaming step C is performed in the ascending portion a of the horizontal feeding endless belt 1 formed of a material having a high air permeability. And a descending part (b), a steam chamber (2) whose upper surface is the back surface of the ascending part (b) is formed, and the endless belt 1 is provided with the steam pipe 4 in the left-right direction which intersects the moving direction of the endless belt 1 and is longer than the left-right width of the endless belt 1.
Since the length of the steam pipe 4 in the left-right direction is longer than the left-right width thereof, steam can be supplied to every corner of the endless zone 1.

(B) Steam outlets 3 are formed in the steam pipe 4 at predetermined intervals, and steam supply pipes 4'are connected to the left and right sides of the steam pipe 4 so that steam can be supplied from the left and right sides. Therefore, even if the left-right width of the endless belt 1 becomes long, the steam having a substantially constant pressure can be supplied from each steam ejection hole 3, so that the left-right width of the endless belt 1 can be made wider than the conventional one, and a large amount of rice The secondary steaming can improve the efficiency.

Has the effect.
