Abstract

PROBLEM TO BE SOLVED: To eliminate the necessity for exchange of materials on the way of drying unnecessary and continue drying treatment to shorten a drying time by a constitution wherein a first drying chamber and a second drying chamber are arranged in parallel while both of them are constituted so as to send drying air into different directions respectively while changing the sending directions alternately. SOLUTION: A first drying chamber 1 and a second drying chamber 2 are arranged so as to be in parallel. As an initial condition, a first drying air sending device 9 is arranged at one end side air ventilating port 5a of the first drying chamber and a second drying air sending device 10 is arranged at the other end side air ventilating port 6b of a second drying chamber. The first drying air sending device 9 and the second drying air sending device 10 send air from different directions into the first and second drying chambers 1, 2 respectively so as not to be opposed and discharge the air from rear opening units 7a. After a predetermined period of time has elapsed, drying air is sent while moving to neighboring synchronized ventilation ports. Drying air is sent from both ends alternately into the first and second drying chambers 1, 2 in such a manner.

Description

DETAILED DESCRIPTION OF THE INVENTION

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention belongs to the technical field of a large-scale drying apparatus for efficiently storing foods such as fish and shellfish and vegetables, mass-produced industrial products and the like at the same time and efficiently drying them.

[0002]

2. Description of the Related Art Conventionally, in a large-sized drying apparatus having a drying chamber for storing and drying a large amount of sardines as a raw material at the same time during the manufacture of a dried product of this type, for example, a drying space is defined. In general, a drying air blowing device including a radiator and a number of blowers, which substantially form a drying chamber, is fixed to one end of a drying chamber.Therefore, heated drying air is supplied from one end of the drying chamber to another end. The object to be dried is blown toward the end side to dry the object stored therein (this is referred to as a first related art). Further, the drying chamber is divided into, for example, two rows, and one drying air blowing device is fixed to one end thereof, and a switching plate is arranged between the drying chamber and the drying air blowing device. In some cases, the switching plate is operated at appropriate intervals during the drying operation to switch the drying air blowing direction, so that the drying air is blown sequentially at each partition of the drying chamber (this is referred to as a second conventional technique).

[0003]

However, the above-mentioned conventional method has the following problems. (1) In the first prior art, since there is a difference in the drying state between the object to be dried on the side closer to the air blowing device for drying and the object on the far side, it is necessary to uniformly dry the same. Requires the replacement of the objects to be dried, which takes extra time. (2) Especially in the production of dried broth, since a large amount is processed within a limited period, the sardines (steamed basket) are packed in the drying room and dried, so the flow resistance of the drying air also increases. In addition, since it is necessary to replace a number of times and dry it uniformly in order to produce a good product, it takes a lot of time and labor all day and night. (3) Since the air blowing device for drying is stopped at the time of replacement of the above-mentioned color filters, there is a useless time which does not contribute to drying during the use period of the drying device. (4) In the second prior art, a large switching plate needs to be installed, so that the device becomes large, and an extra installation space is also required. (5) Automation is required due to the need for complicated techniques for drying, such as differences in raw materials and the state of the outside air, and lack of skilled personnel.However, the above-mentioned problems are a bottleneck. I have.

The problem to be solved by the present invention is that it is not necessary to replace raw materials in the course of drying by human naval tactics, the drying process is continued, the drying time can be shortened, and good products can be manufactured. An object of the present invention is to provide a drying apparatus which can be automated in response to a difference or an outside air condition.

[Means for Solving the Problems]

(Solution 1) In order to achieve the above object, in the invention according to claim 1, ventilation holes for drying air are arranged at both ends of the defining portion of the drying space, and the ventilation holes at the ends are arranged side by side. A first drying chamber and a second drying chamber, which are connected in parallel so that the ventilation directions are parallel to each other; and alternately move between one end sides of the first drying chamber and the second drying chamber, respectively. A first drying air blowing device for blowing drying air from a ventilation opening, and the other end sides of the second drying chamber and the first drying chamber in synchronization with the first drying air blowing device in a direction opposite to the moving direction. And a second drying air blowing device that alternately moves between the air outlets and blows the drying air from the vent holes of the moving destinations.

Therefore, the first drying chamber and the second drying chamber are arranged so as to be parallel to each other, a first drying air blowing device is arranged at one side ventilation port arranged side by side, and the other side ventilation ventilation is arranged side by side. The second drying air blowing device is arranged in the mouth. Then, the first and second drying air blowing devices blow the drying air into the first and second drying chambers so as not to face each other from different directions. Further, the first and second drying air blowing devices synchronously move to adjacent ventilation ports and blow drying air.
As a result, the first and second drying chambers are alternately blown with dry air from both ends, and the drying action is equalized in each of the drying chambers. Even without it, it will be dried evenly.

(Solution means 2) In the invention according to claim 2,
The drying apparatus according to claim 1, wherein the first and second drying air blowing devices are formed by integrally mounting an air heater and a blower on a movable carriage.

[0008] The first and second drying air blowing devices are separated into one end and the other end of the first and second drying chambers by the movable carriage and are alternately moved and then blow the drying air. The air blow destination is always in an open state to improve the flow of the drying air, and by performing the movement and blowing the drying air a plurality of times, the drying conditions of the drying object can be determined regardless of the position of the object to be dried. The same can be achieved. As described above, the operation of the movable cart only needs to be instructed in accordance with the internal drying conditions, so that the drying operation can be easily automated.

(Solution means 3) In the invention according to claim 3,
3. The drying apparatus according to claim 1, wherein the first drying chamber or the second drying chamber includes a shutter for controlling an exhaust direction of the applied drying air.

The exhaust side of the drying air in the first and second drying chambers is in an open state, and the exhaust can be freely exhausted to the rear side. When the exhaust cannot be performed in that direction, the shutter can be switched to the release side by the exhaust direction control shutter. For this reason, pollution control can be performed without lowering the efficiency, and the installation conditions are eased.
