Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for subjecting grain to steaming, heating and cooling while conveying the grain in a closed container.

For example, when steaming grains such as corn, millet, and soybeans to be used as feed for livestock such as cows and pigs, the grains are placed in a closed container and steam is pumped through the container. In terms of automation, it is preferable to carry out the steaming while conveying the ingredients to a certain point. For this purpose, various devices have been devised in the past. For example, as shown in FIG. There is one that carries the material to be processed (grain) in a zigzag pattern and steams it.

However, in this case, the return path 2b of the conveyor 2 cannot be used as a conveyance surface and is wasted, so the entire device becomes large in order to perform sufficient steaming treatment, and the return path 2b is not used as a conveyance surface. There is a problem that it becomes a hindrance and the processing efficiency is also inferior.

The present invention takes the above points into consideration and aims to provide a processing apparatus that makes effective use of the inside of a processing container.

In order to achieve this object, in the present invention, a plurality of conveyance surfaces are formed in the vertical direction within the closed container, and a conveyor surface is provided at the front part in the conveyance direction of each conveyance surface except for the lowest stage, extending over the entire length in the width direction. The opening is formed so as to face the conveyance surface immediately below, and a linear traveling body is provided in a zigzag shape from above along each conveyance surface, and its starting and ending ends are connected to form an endless structure. A conveyor is constructed by sequentially attaching scrapers in different directions at predetermined intervals, numerous small holes are formed on each conveying surface, and a grain input port that can be freely closed is formed in the container corresponding to the starting end of the conveyor. At the same time, a discharge port that can be freely closed is formed corresponding to the terminal end, and
This is a container with an inlet for introducing processing gas such as steam.

With this structure, when grains and processing gas such as steam are fed into the container, as the scraper runs, the grains move in a zigzag pattern along each conveyance surface, falling from the front opening to the lower conveyance surface. ,
During the movement, the grains are processed by the processing gas that passes through the small holes in the conveying surface and the processing gas in the container.

Therefore, according to this invention, since the grain is moved by the running of the scraper, there is no wasted space like the return path of a belt conveyor, and sufficient processing can be performed even in a narrow space. This has the effect of ensuring even distribution and high processing efficiency.

Hereinafter, one embodiment of the present invention will be described based on the accompanying drawings 2 to 4.

As shown in FIGS. 2 and 3, a middle plate 11 slightly downward to the left is located in the center of the rectangular cylindrical container 10 with both ends closed in the height direction.
is provided with its both ends separated from the container 10, the upper surface of this intermediate plate 11 serves as an upper conveying surface 12a, and the slightly downwardly rightward bottom surface of the container 10 serves as a lower conveying surface 12b.
Therefore, the conveyed object that has been moving downward to the left on the conveying surface 12a falls from its front end onto the conveying surface 12b. That is, the gap between the left end of the middle plate 11 and the container 10 becomes an opening as referred to in the claims. On the portion of the intermediate plate 11 corresponding to the conveyance surface 12a and on the bottom plate conveyance surface 12b corresponding to the steam inlet 13 of the container 10, a fourth
As shown in the figure, numerous small holes 14' are formed, and steam evenly spreads throughout the interior of the container 1 through these small holes 14'. Needless to say, the size of the small hole 14' is set to a size that does not allow grain to pass through.

Sprockets 14, 14 are provided at both ends of the container 10, and one sprocket 14 is connected to a motor (not shown) provided in the container 10 to serve as a drive side. Two sprockets 14 are provided at one end in the axial direction, and a roller chain 15 is stretched between each sprocket, and tension is applied to the chain 15 by a tension sprocket 16. Middle plate 11
A rail 17 is provided along the running direction of the chain 15 on the top surface and the bottom surface of the container 10, and as shown in FIG. 3, the chain 15 is fitted onto this rail 17 and runs to prevent meandering. The number of running chains 15 is not limited to two, but may be one or three depending on the width of the container 10.
The number may be selected as appropriate.

Scrapers 18 in the width direction of the conveying surface are attached to the chain 15 one after another at predetermined intervals. The scraper is a plate 18a fixed to the chain 15.
A rubber plate 18b is placed on top of the rubber plate 18b with its upper and lower edges protruding, and then a plate 18c is placed on top of the rubber plate 18b, and the three parts are secured with screws.As shown in FIG. 4, the scrapers 18 of both chains 15 are The opposing parts overlap in the conveyance direction. At the top of the container 10, as shown in FIG. 2, a screw feeder 19 is provided on the upper right side. A discharge port 20 faces the starting end of a conveyor A consisting of a chain 15 and the like. Water is put into the feeder 19 to shield the input port 21 and the inside, and the water passes through the hole 23 of the drive shaft 22 and the valve 2.
4 can be opened and closed to allow inflow. The valve 24 may be controlled based on a liquid level gauge, and
The water level may be controlled by overflow. In this way, passing the grain through water has the effect of increasing moisture during the steaming process.

A safety valve 25 is provided at the tip of the feeder 19 to prevent abnormal pressure rise within the container 10, and an inflow rate adjusting plate 26 is provided within the container 10 corresponding to the outlet 20 and the like. A discharge port 27 is provided on the bottom surface of the container 10 corresponding to the end of the conveyor A,
Grain after processing is dropped from this discharge port 27 into a feeder with a closing function or the like.

The embodiment is configured as described above, and its operation will be explained next.

Now, when grain is put into the input port 21 while steam is being sent into the container 10,
The grains are passed through water by the feeder 19 and fall onto the conveying surface 12a from the outlet 20, and as the scraper 18 runs, the grains move along the conveying surfaces 12a and 12b, and steam passes through the small holes 14' and enters the container 10. Steam is used for steaming,
It flows out from the outlet 27.

In addition, although the above-mentioned embodiment was a case of steaming treatment, it goes without saying that the present invention can be adopted in all gas treatment apparatuses such as heat treatment such as heating and cooling.

Further, the number of stages on the conveying surface may be appropriately set in consideration of the processing time.
