Description

[Detailed description of the device] [Industrial applications]

The present invention relates to a koji stocker for temporarily storing koji produced by a koji making device at a relatively low temperature without deterioration in quality.

[Prior art]

Generally, the structure of the koji stocker has a koji feed port on one side and an endless belt stretched over the floor of a long closed chamber with a koji takeout port on the other side It is a structure that rotates in the same direction. Further, in a koji stocker in which the koji supply port and the koji take-out port are in the same direction, the rotation of the belt is reversed when the koji is supplied and taken out. Conventionally, the endless belt of a koji stocker has a punching belt structure in which a large number of holes are perforated in a metal strip plate over the entire length.

[Problems to be solved by the device]

In the conventional device, since the entire surface of the endless belt is the punching belt, when the koji is not on the punching belt, air easily escapes from the part and the temperature of the koji cannot be adjusted sufficiently. The present invention is intended to solve this point.

[Means for Solving the Problems]

Therefore, an attempt was made to make the endless belt in the koji stocker a punching belt capable of ventilating only the part where koji is stocked, and the other part to be a non-opening belt through which air does not pass. That is, the endless belt is stretched around the floor as a belt conveyor, and the koji stocker is a koji stocker that has both sides as wall surfaces with respect to the traveling direction of the endless belt and at least one of the front and rear is surrounded by a discharge damper. (1) is the direction in which the perforated belt portion (1a) having a length ensuring the air permeability of the portion where koji is loaded and stocked and the remaining non-air permeable non-perforated belt portion (1b) travel The koji stocker is characterized in that it is arranged in the form of a strip extending to the. The term "perforated" as used herein is not limited to a state in which a hole is provided in metal by punching or the like, and also includes a net-like one having a hole.

[Action]

With this structure, in a koji stocker where the koji feed port and the koji take-out port are in opposite directions, the koji is set by installing the boundary between the perforated belt and the non-perforated belt at the start of the koji loading. The temperature of koji can be adjusted effectively even when pouring. Further, even when the koji is discharged, even if the endless belt rotates and moves, the subsequent non-perforated belt portion appears on the floor surface and the air to be blown cannot pass through the koji-free portion. Further, in the koji stocker in which the koji supply port and the koji take-out port are in the same direction, it is not necessary to change the koji layer thickness depending on the amount of koji as well as the above-mentioned action. In other words, when storing koji, the damper at the supply port is usually adjusted so that the layer thickness is almost uniform over the entire floor surface.In this case, it is necessary to set the layer thickness that matches the maximum loading capacity. The state is the same as when koji is being put in, and the temperature of koji can be adjusted effectively.

【Example】

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a front view of the koji stocker of the present invention, FIG. 2 is a side view of FIG. 1, and FIGS. 3 to 6 are views showing operating conditions. FIG. 7 is a plan view of the belt of P portion in FIG. 4, and FIG. 8 is a plan view of the belt of Q portion in FIG. As shown in these drawings, in the koji stocker of the present invention, a steel endless belt (1) is stretched between rollers (2a) (2b) provided at both front and rear ends. In this koji stocker, the endless belt (1) is an endless belt in which a perforated belt portion (1a) for loading koji and a remaining non-perforated belt portion (1b) extend in a belt shape in the traveling direction of the belt. Is. That is, only the perforated belt portion (1a) where the koji (3) is stocked is used as a punching belt, and the other wraparound portion is a non-opening non-perforated belt portion (1b). I am trying. As can be seen in Fig. 3, a limit dock (4) is provided at the boundary between the perforated belt portion (1a) and the non-perforated belt portion (1b), so that a fixed position is automatically set at the start of koji feeding. I am able to make you wait. In addition to the combined use of the limit dock (4) and the limit switch, a photoelectric switch, a proximity switch or the like may be used to achieve the same effect. Since the endless belt (1) after the limit dock (4) has become a perforated belt portion (1a) over a length of about 1/2, mount the koji (3) as shown in FIG. You can As shown in FIG. 7, the non-perforated belt portion (1b) is located in front of the direction in which the koji (3) is placed in the belt traveling direction.
Has become. In this state, the endless belt (1) rotates clockwise to stock the koji in the stocker. Then, as shown in FIG. 5, when the limit dock (4) hits the discharge damper (6) at the front (right side in the figure), the endless belt (1) stops and the length with the rear wall (7) of the stocker stops. The koji (3) is stocked on the perforated belt portion (1a) over the entire length of the belt, and the air permeability is secured, and the koji (3) is temporarily stored at a relatively low temperature without deteriorating the quality of the koji. Next, when the discharge damper (6) is opened and the koji (3) is discharged, as the endless belt (1) rotates and moves forward (to the right in the drawing), as shown in FIG. The hole belt part (1b) appears on the floor of the stocker, and this part is the non-open endless belt of the part where the koji (3) is not stocked, so if only part of it is discharged and the rest is stocker. Even if it is left inside, air does not escape from that part, and the temperature of the koji can be adjusted easily. As a result, useless fan power can be saved. Also, Figures 9 and 10 show the layer thickness adjustment damper (5) for the koji feed port.
FIG. 3 is a diagram showing the operation status of the koji stocker on the front wall (8) at the front (to the right of the drawing) with the discharge damper (6) at the koji take-out outlet in the same direction as the traveling direction of the endless belt (1). FIG. 9 shows a state in which the layer thickness adjusting damper (5) is matched with the maximum load of koji and a small amount of koji is stocked after the completion of feeding. The floor surface in front (on the right side of the figure) is an endless belt (1b), and no air path occurs even without the koji (3). FIG. 10 is a diagram when discharging, and even in a koji stocker in which the koji supply port and the koji extraction port are in the same direction, the temperature of the koji can be adjusted in all the processes from the start of charging to the completion of discharging, and The layer thickness adjusting damper may be fixed. Needless to say, the endless belt of the present invention can be applied to a stocker equipped with a discharge damper (6) before and after the stocker.

[Effect of device]

Since the koji stocker of the present invention has the above-mentioned structure, the temperature of koji can be adjusted in all the processes from the start of charging to the completion of discharging. Moreover, the waste of fan power can be saved,
The effect of saving energy was obtained. Also, the manufacturing cost of the endless belt has been reduced to about 80%.
