Description

Apparatus for drying agricultural and aquatic products}

The present invention relates to an agricultural and marine product drying apparatus, and more particularly, to an agricultural and marine product drying apparatus having a configuration in which drying racks are stacked in multiple stages in a drying chamber of a hot air circulation type dryer and automatically put and take out dry items in each drying rack.

BACKGROUND ART Hot air circulation dryers are known as a device for drying agricultural products such as rice pepper and marine products such as seaweed seaweed fish. Representative hot air circulation dryer is configured as shown in FIG. The housing 1 is separated into a drying chamber 2 and a hot air circulation chamber 3, and an intake fan 4 and an exhaust fan 5 are provided on both sides of the drying chamber 2. A heat generator 6 such as a burner is provided on a surface adjacent to the drying chamber 2 of the intake fan 4.

When the agricultural and aquatic products to be dried (hereinafter referred to as "dry goods") are put into the drying chamber 2 and heat is generated by the heat generator 6, the wind is blown into the drying chamber 2 by the intake fan 4, and the wind is generated by the heat generator. Passing (6) results in hot air having a high temperature to dry the dry matter and escaped by the exhaust fan (5). The escaped wind passes through the hot air circulation chamber (3) and flows back into the drying chamber (2) by the intake fan (4), and the temperature rises by the heat generator (6) again to dry the dry matter and the drying chamber by the exhaust fan (5). (2) get out. As described above, the hot air circulates and the dried object continues to dry.

By the way, conventionally, as a method of loading the dry items in the drying chamber, a large number of trays are loaded on a trolley and put in a drying chamber, or when the drying is completed, the trolley is pulled out to remove the dry matter from each tray and a new dry matter is added. Is done. On the other hand, there is also a method of loading the dry object by the conveyor method. However, when the conveyor system is applied, the amount of dry matter dried at one time is very small.

In addition, in the conventional hot air circulation type dryer, it is required that hot air of uniform temperature and humidity pass the dry matter at a uniform wind speed and air volume. Otherwise, the object is not dried uniformly, and the value as a commodity decreases.

In addition, there is a need to efficiently replace the dry matter. It is preferable that the drying chamber be large for mass drying, but if it becomes too large, it takes much manpower to replace the building, and the economic efficiency is lowered. Bell

Accordingly, an object of the present invention is to ensure the drying quality by stacking the dried product to be put into the drying chamber in multiple stages in the drying chamber to ensure that the hot air passes evenly, and automatically puts the dried products into the drying rack stacked in multiple stages to dry the agricultural and marine products It is to provide an agricultural and marine products drying apparatus having a structure to automatically withdraw.

Summary of the Invention

2a to 2d is a conceptual diagram for explaining the outline of the agricultural and marine products drying apparatus according to the present invention. In Fig. 2A, a plurality of drying racks 11 are stacked in multiple stages in a drying chamber. The drying chamber may be viewed as the drying chamber 2 shown in FIG. Therefore, also in FIG. 2A, hot air is moderated by a fan from one side of the drying chamber to the other side (the hot air passes between the drying racks).

Hook-shaped clasps 13 and 13 'are attached to both ends (left and right in FIG. 2A) of each drying stand 11 stacked in multiple stages in the drying chamber. In addition, each drying stand 11 is coupled by a guide (not shown in the figure) so as to linearly move from side to side in the drawing. Clasps 13 and 13 'attached to both ends of the drying rack 11 are engaged with the drying rack pullers 15 and 15' outside the drying chamber and serve to linearly move the drying rack 11 to the left or the right. . For example, in FIG. 2A, in order to pull out one of the drying racks to the right outside the drying chamber, the drying rack puller 15 'may be hooked on the right clasp 13' of the drying rack 11 and pulled to the right.

Under the structure as shown in Fig. 2A, it is very efficient to load or remove a dry item from the drying rack between each drying rack. The drying rack 11 is easily pulled out to the outside by using the drying rack puller 15 outside the drying chamber, and after loading the dried material, the new drying material is loaded, and the drying rack 11 is pulled by the opposite drying rack puller 15 '. This is because it only needs to put the drying rack 11 into the drying chamber. In addition, since the drying racks are stacked, the drying racks can be horizontally drawn out of the drying chamber while vertically moving the drying rack pullers 15 and 15 'for each floor.

Figures 2b-d show the mechanization of an external dryer puller in the basic structure of Figure 2a. As in Fig. 2A, a plurality of drying racks 11 are stacked in multiple stages in the drying chamber. The difference from FIG. 2A is that rollers 17 and 17 'for pulling the drying stand 11 are provided on both sides outside the drying chamber. The puller belt 19 is wound around the left roller 17, and another end of the puller belt 19 is attached with another latch for hanging the rack clasp 13. This structure is the same also in the right roller 17 '. However, a hopper 21 for supplying a new object 13 is located at the upper part of the puller belt 19 'wound on the right roller 17'. In addition, a collecting barrel 22 is installed at the lower portion of the right roller 17 'to collect the dried items 13.

In FIG. 2B, the drying rack 11 should be able to be wound on the rollers 17, 17 'in the form of a belt. Preferably, the foot is made of synthetic resin, bamboo, royal bone, or the like, with airy weaving. This is because it can be wound on the rollers 17 and 17 'flexibly, and the ventilation is excellent, and the drying effect by the hot air is excellent. Hereinafter, the drying rack which can be wound on a roller is called "drying belt."

In addition, the hopper 21 may be provided in a different way to be replaced according to the object to be dried. For example, in the case of dry particles of small particles such as grains, the same thing as shown in FIG. 2B may be used, and in the case of dry products such as red pepper, the hopper may be vibrated using a vibrator so that the red pepper is evenly discharged easily. will be. In addition, in order to dry the object to be crushed may be installed a grinding blade in the hopper, if necessary, the structure to discharge the dry object out of the hopper using an extrusion screw.

Also, in Fig. 2B both rollers 17, 17 'must be rotated by ratchet bearings. Therefore, the rollers 17 and 17 'are rotated by the power source (motor) in the forward direction, and are in the idle state where they can rotate without any resistance in the reverse direction. In the present specification, the forward rotation refers to a rotational direction in which a roller winds a drying belt, and the reverse rotation is defined as a direction of loosening a belt.

The operation on the structure of Fig. 2B will be described with reference to Figs. 2C and 2D. FIG. 2C shows the operation of loading the dry object 23 onto the drying belt 11. In the state immediately before the display in Fig. 2C, the drying belt 11 is wound by the right roller 17 'and pulled to the right. In this state, when the left roller 17 rotates forward, the puller belt 19 is wound and the latch 13 of the drying belt 11 is hooked and the drying belt 11 is pulled to the left side. Then, since the right roller 17 'is reversely rotated by the ratchet bearing, the drying belt 11 wound around it is released and drawn into the drying chamber. At this time, the discharge port 25 of the hopper 21 is opened and the dry matters 23, such as grain pepper laver, contained therein are poured into the drying belt 11. In this way, the drying belt 11 enters into the drying chamber in the state where the to-be-dried object 23 is loaded.

Figure 2d shows the action of withdrawing the dried to the outside. 2C, the right roller 17 'rotates forward when the dried object introduced into the drying chamber is completed by the same action as in FIG. 2C. The latch is closed by the puller belt (which is already wound on the roller 17' in FIG. 2D). The drying belt 11 is also pulled to the right. Of course, at this time, the left roller 17 is free to rotate back by the ratchet bearing. The drying rack belt 11 drawn to the right is rolled out of the drying chamber and wound on the right roller 17 ', and the dry matter 23 loaded on the drying belt 11 is poured into the collecting container 22. After pouring the dry object 23, the left roller 17 rotates forward again, pulling the drying belt 11 to the left, and at this time, the outlet 25 of the hopper 21 is opened again, and the same action as in FIG. 2C is repeated. Proceed.

The conceptual construction and function of the present invention described above can be made the same for each drying belt belt stacked in the drying chamber. Thus, the rollers 17, 17 'and the hopper 21 should be capable of vertical movement for each layer of the drying belt to be moved.

Example

An embodiment of the present invention described above will be described with reference to FIGS. 3 and 4. Fig. 3 highlights the conveying mechanisms 27a and 27b of the drying belt, and Fig. 4 shows the overall configuration of the agricultural and marine product drying apparatus of the present invention.

FIG. 3 shows that the transfer mechanism shown in FIG. 2B is symmetrically installed on both the left and right sides of the drying chamber. In FIG. 2B, only one transfer mechanism for horizontally moving each drying belt 11 from side to side has been described to explain the concept. However, in Fig. 3, the transfer mechanisms 27a and 27b are symmetrically installed on the left and right sides of the drying chamber so that each transfer mechanism is in charge of one drying belt. As a result, two drying belts are simultaneously transported from side to side, thereby loading and removing the dried object, thereby improving drying efficiency.

3, it can be seen that the drying chamber 26 and the pair of transfer mechanisms 27a and 27b, in which a plurality of drying belt belts 11 are stacked, consist of one frame as a whole. Then, the carrier 29 is attached to the lower part of the entire frame so that the drying chamber 26 and the transfer mechanisms 27a and 27b can move in the front and back directions (the direction of protruding from the paper and the paper entering direction) of FIG. Referring to FIG. 4, it can be seen that the frame itself as shown in FIG. 3 enters and exits the inside of the drying apparatus. The conveying mechanisms 27a and 27b in FIG. 3 are exaggeratedly expressed compared to the size of the drying chamber 26. 4, the relative sizes of the transfer mechanisms 27a and 27b and the drying chamber 26 will be seen.

3, the left conveying mechanism 27a and the right conveying mechanism 27b are provided with double the mechanisms shown in FIG. 2B on both sides of the drying chamber. That is, one set of the first left roller 17a and the first right roller 17a 'is coupled to one set of the second left roller 17b and the second right roller 17b'. And each conveyance mechanism 27a, 27b is connected by the winch mechanism 31, 31 'so that it can move up and down in the both sides of the drying chamber 26. As shown in FIG. Component 33 on the upper surface of the drying chamber 26 is a control box for controlling the rotational movement and the vertical movement of the transfer mechanisms 27a and 27b. In addition, it can be seen that the object collecting barrels 22a and 22b are provided below the first right roller 17a 'and the second left roller 17b.

The operation of the embodiment shown in Figure 3 is the same as the operation described with reference to Figures 2b, c, d. However, two drying belts 11 are simultaneously transported from side to side by a pair of transfer mechanisms to load or remove the dry items. Thus, each one transport mechanism is responsible for one belt of drying racks.

FIG. 4 is an external sectional view of the entire dryer including the drying chamber and the transfer mechanism shown in FIG. The housing 35 is separated into a drying chamber 26 and a hot air circulation chamber 37, and an intake fan 39 and an exhaust fan 41 are provided on both sides of the drying chamber 26. A heat generator 43 such as a burner is provided on a surface adjacent to the drying chamber 26 of the intake fan 39. The tube " 45 " extending to the outside of the heat generator 43 is in communication. In addition, the component "47" on the left side of the heat generator 43 is a damper capable of adjusting the direction of the hot air.

The overall drying function of the embodiment according to the invention is as follows. When the dry matter is put in the drying chamber 26 and heat is generated in the heat generator 43, when the wind is blown into the drying chamber 26 by the intake fan 39, the wind passes through the heat generator 43 and the damper 47. At the same time, it becomes hot air having a high temperature to dry the object to be dried and escaped by the exhaust fan 41. The escaped wind is circulated again through the hot air circulation chamber 37.

3, the drying chamber 26 and the transfer mechanisms 27a and 27b coupled thereto are drawn out of the housing 35 by the carrier 29, and have the same action as in FIG. Replacement of the building takes place.

Figure 5 shows an embodiment of the rack belt used in the present invention. Previously, the drying belt was said to have the flexibility and breathability to be wound on the roller, but as the material, a foot woven by connecting a foot 49 such as synthetic resin or bamboo with a thread 51 is most suitable. In addition, if the foot (dryer belt) is continuously wound and loosened on the roller, the foot may be stretched in the longitudinal direction (X direction in FIG. 5), which may cause the whole to sag downward. It is conceivable to insert two steel wires 53. Steel wire is a thin metal wire weave made of stainless steel, etc., and has elasticity, so it can reinforce strength in preparation for the increase of the foot without any obstacle to the role of the drying belt.

The present invention is not limited only to the drying of agricultural products described above. For example, it can be used for drying food waste and other ripening.

As described above, according to the present invention, the following effects can be obtained.

1) Since drying belts are stacked in multiple stages and hot air passes through each stage, a large amount of dry items can be dried uniformly even in a narrow space.

2) Even when replacing the dry items, there is no need for a person to climb on the drying stand located on the higher floor, and the dry goods can be replaced by mechanically pulling out the drying belt by the transfer mechanism moving up and down.

3) There is no need for a separate tray because the object is loaded on the drying belt.

4) Since the present invention is basically a conveyor type, the input and withdrawal of the dry matter can be made automatically without a person.
