Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a drying device that dries refined eggs by blowing high-speed air from above and sucking moisture from below while transporting refined eggs on a conveyor. The present invention relates to a drying device for continuous drying.

Eggs, which are commonly eaten in large quantities, are living creatures, and if they are collected as they are, they do not look good due to dirt, etc. and are unsanitary. Therefore, the surface of the eggs is first washed with water and dried, and after being sorted, they are packed immediately. There is.

However, in conventional egg washing equipment, after egg washing and before entering the fan drying process, there is a step in which powerful air is blown from above the eggs to remove the refined water adhering to the eggs. In this process, the adhering water on the upper half of the egg is removed, but there is still a considerable amount of water adhering to the lower half of the egg, which remains at the top and is transported to the fan drying process mentioned above. However, there were times when it was not completely dried.

If the surface of the egg is not completely dried and the egg is packed, the inside of the pack will be in a high temperature state, which will cause scratches to form on the surface of the egg. Therefore, in order to completely remove and dry this accumulated adhering water, for example, an egg washing machine (transferring in 6 rows) with an egg washing capacity of 1,500 eggs per hour must have two or more long tables, and the space is also large. Not only that, but the equipment cost is also high and it is uneconomical. However, the present invention solves the various deficiencies of conventional drying equipment as described above, and aims to eliminate almost all moisture adhering to the surface of eggs so as to contribute to shortening the drying equipment. As a result, it is possible to prevent the appearance of marks on the surface of eggs after packaging.

The structure of the present invention includes a conveyor that supports and transfers the surface of washed eggs at several points, and a conveyor installed above the conveyor so that its longitudinal direction is approximately perpendicular to the conveyor, and blows out high-speed air downward. a slit, and a suction device that closes an upward suction port provided below the conveyor corresponding to the egg transfer path and at a position directly below the slit or slightly closer to the direction of movement of the conveyor than directly below the slit to suck out moisture; Regarding the positional relationship between the conveyor and the suction device, when the egg position is above the suction port, the suction port approaches the conveyor to a position where it should almost touch the bottom surface of the egg, and when the egg position is not above the suction port, the suction port is close to the conveyor. and a mechanism adapted to be spaced downwardly.

In the present invention, the term "egg position" refers to the position at which eggs supported by egg trays and transferred on the conveyor should exist. In the present invention, while the washed eggs are placed at a certain position on a conveyor and transferred, high-speed air is blown from a slit above the eggs to blow the water that has landed on the egg downwards, and then the water that has accumulated below the egg is blown down. By suctioning and removing water from below the egg, adhering water is almost completely removed from the entire surface of the washed egg.

Examples of the apparatus of the present invention will be described below.

Figures 1 and 3 are front views of the main parts of the first embodiment, showing the suction ports at the lowest and highest positions, Figure 2 is a side view of Figure 1, and Figure 4 is a front view of the main parts of the first embodiment. FIG. 3 is a side view of FIG. In the figure, arrows indicate the direction of movement of the conveyor. The conveyor for transporting the eggs 1 has two endless chains suspended between a drive sprocket and a driven sprocket, which are rotatably mounted on the machine frame, and two endless chains that are rotatably placed between the endless chains and are spaced apart from each other at an appropriate distance. It is composed of a plurality of axles 2 that are supported by a bag, and an appropriate number of egg holders that are fixed to the axles 2 at regular intervals. One egg tray consists of four plate-shaped support plates 3 and 4 that protrude at right angles to the shaft 2 and have circular outlines centered on the rotation axis of the shaft 2, of which the outermost two large The distance between the diameter support plates 3 is set to be a distance slightly smaller than the long axis of the egg, and two small diameter support plates 4 are arranged at appropriate intervals inside the diameter support plates 3 for a total of 4.
Two support plates are fixed to the shaft punch 2.

The diameters of the outline circles of the two large-diameter support plates 3 are the same, the diameters of the outline circles of the small-diameter support plates 4 are the same, and the diameters of the outline circles of the two small-diameter support plates 3 are the same.
The diameter of the support plate 4 is larger than that of the small diameter support plate 4. Therefore, if the outer peripheral edges of the four support plates 3 and 4 are bent in a direction parallel to the shaft village 2, a convex curve will be drawn on the shaft punch 2, and this curve will be approximately similar to the vertical cross-sectional curve of the outer shell of an egg. to be determined. The space between two adjacent egg trays on the moving path is the egg position, and these two egg trays form a set, and the eggs are placed on top of them with their long axes parallel to the remote village 2. When the egg is set so that it does not fall. The slit 5, which is connected to the blower and blows out high-speed air, is located above the conveyor, and its longitudinal direction is almost perpendicular to the conveyor, and it closes downward and is fixed to the machine frame. It is formed to have a dimension slightly longer than the major axis of 1.

The suction tube 6' connected to the vacuum pump via a trap or the like is a cylindrical tube with a suction port 7 opened upward, and the suction port 7 is made of cylindrical rubber or thermoplastic resin. The lower part of the suction pipe 6 has a bendable connecting part connected to the water suction pipe. One suction pipe 6 is provided corresponding to each egg position between two adjacent Fujii 2, and a suction port 7 is provided directly below the slit 5 or slightly closer to the direction in which the conveyor travels from directly below the slit 5. The suction ports 7 are connected to each other in a state in which the suction ports 7 are aligned at the same level.

A fixing plate 8 that protrudes horizontally outward is fixed to each of the suction tubes 6 at both ends, a guide piece 10 is fixed to the upper surface of the fixing plate 8, and a spring 9 that expands and contracts in the vertical direction is attached to the lower surface of the fixing plate 8. It is supported by the machine frame through. The lower surface of the spring 9 remains in a fixed position and does not move. As the spring 9, for example, a spring-type cylinder is used. The two guide pieces 10 have the same shape, have a mountain-shaped outline as a guide surface, and are formed to be thicker than the large diameter support plate 3 of the egg receiver. The chevron-shaped guide surface is in a position where it contacts the outer peripheral surface of the large support plate 3.

The guide piece 10 is fitted between the large-diameter support plate 3 of one detached village 2 and the large-diameter support plate 3 of the adjacent punch 2, so that the guide surface of the guide piece 10 does not contact the large-diameter support plate 3. At this time, the positional relationship between the suction tube 6, the fixing plate 8, and the guide piece 10 is set so that the end surface of the suction port 7 of the suction tube 6 comes into almost contact with the lower surface of the egg at the egg position, and the suction tube The spring 9 is restricted so that the spring 6 does not move upward beyond this position. The chevron shape of the guide surface of the guide piece 10 is such that the slope of the surface that the large support plate 3 contacts after passing the top point of the chevron is more inclined than the slope of the surface that the large support plate 3 first contacts as the conveyor advances. It is formed into a shape in which the suction pipe 6 does not come into contact with any support plate while the large diameter support plate 3 is in contact with the guide surface. The position of the suction port 7 of the suction tube 6 may be directly below the slit 5, but it is preferable to position it slightly toward the advancing direction of the conveyor. The reason is that even after the egg passes directly under the slit 5, it is still blown with high-speed air from the slit 5, which is able to prevent the attached water from being blown downwards, and the attached water is blown away by its own weight, even if it is a little. This is because it falls further down. Next, a numerical example of the drying apparatus (for chicken eggs) of the present invention according to the first embodiment will be described.

・The dimensions of the main parts of the drying device of the present invention are as follows: center distance between two shafts of the conveyor is 48, and one shaft 2 has six egg trays (6
(column transfer), the suction port 7 is set 25 ribs from just below the slit 5 toward the direction of conveyor movement, and the diameter of the suction port is IQ rib,
Suction air volume 0.05 w/min, conveyor drying capacity 15,000
■Drying was carried out on day/time Z. After passing through the drying device of the present invention, the eggs pass through a fan drying section using an air blower on the same conveyor to complete the drying process. After passing under the slit 5, the eggs were collected before entering the fan drying section, and the amount of water attached was measured. As a result, in the drying apparatus of the present invention, the remaining amount of water attached to ZI eggs was 0.03 to 0.05 hours. A drying device equipped with only the slit 5 that blows out high-speed air under the same conditions was used as a control example, and when the egg was collected after passing under the slit and before entering the fan drying section, the remaining amount of water attached to one egg in the control example was It was 0.2 evening. Therefore, in consideration of the individual variation in the degree of drying of eggs, in order to completely dry the eggs, it was necessary to pass through two or more fan drying sections in the control example, but in the case of the present invention, it was necessary to pass through two or more fan drying sections. I was able to get the same result just by passing the part. The slit that blows out high-speed air can be connected to a blower, and the suction pipe can be connected to a vacuum pump to perform their respective functions, but it is also possible to connect the suction port of one blower to the suction pipe via a trap, etc. Even if the outlet is connected to the slit, the same function can be achieved, and one blower can be used effectively.

The effects of the first embodiment configured as described above will be explained.

As a pre-process of the drying device of the present invention, the eggs 1 are washed with water on the conveyor in advance, and the washing water adheres to the entire surface, and the eggs 1 are placed on the egg tray with the longitudinal direction facing two rutted areas. The egg 1 is transferred with its lower side supported. When the egg 1 is transferred to the lower part of the slit 5 by the conveyor, the water that lands on the egg 1 is blown away from the tip of the egg 1 by the high-speed air jetting out from the slit 5, and is blown away and collected on the lower circumferential surface of the egg 1. Since the egg 1 is supported by the support plates 3 and 4 of the egg receiver in a point-contact manner, the water that lands on the egg is blown away below the egg without resistance.During this time, both outermost support plates 3 of the axis village 2 The guide piece 10 starts to come into contact with the guide piece 10, and the guide piece 10 is pushed down along the gentle upward slope of the guide surface, and the spring 9 is compressed.

When the large-diameter support plate 3 crosses the top of the chevron of the guide surface, the guide piece 10 is pushed up by the elasticity of the spring 9 along the steep downward slope, and when the contact between the large-diameter support plate 3 and the guide piece 10 is released, suction is applied. The tube 6 is pushed up by the spring 9 to the regulated top dead center, and the suction port 7 almost comes into contact with the lower surface of the egg, as shown in FIG. Since the guide piece 10 is in contact with the large-diameter support plate 3 of the egg tray, the suction tube 6 can take a vertical stroke without interfering with the movement of the small-diameter support plate 4. The vacuum pump is constantly operated while the conveyor is moving, and the vacuum pump
When the egg 1 is almost in contact with the lower circumferential surface of the egg 1, the adhering water blown and collected on the lower circumferential surface of the egg 1 is immediately sucked up by the suction port 7, and the entire surface of the egg 1 is almost free of moisture. Then, it is transferred to the next step, a fan drying section (not shown). As a continuous refining conveyor for eggs, the eggs are then inspected and packed immediately. All the suction tubes 6 are connected together with the same level with the top dead center at the position where the suction port 7 almost touches the lower circumferential surface of the egg 1, so all the suction tubes 6
At the same time, all the eggs in the horizontal row corresponding to the two monkeys in the remote village passing through the same motion are sucked in the attached water at the same time. 5a to 5c are main side views of the second embodiment, showing the operating state.

The arrow in the figure indicates the direction of movement of the conveyor. In the second embodiment, the overall structure of the conveyor is the same as in the first embodiment, and the only difference is the relative motion relationship between the conveyor and the suction pipe 6 that sucks the attached water, so only this point will be explained. . That is, in the first embodiment, the suction pipe was moved up and down, whereas in the second embodiment, the conveyor was partially moved up and down. Each suction tube 6 provided in the same manner as in the first embodiment is fixed by an appropriate method at a position where the suction port 7 should substantially contact the lower surface of the egg 1 at the egg position. Two guide pieces 10 having a chevron shape with a slope and a steep slope similar to those in the first embodiment have their guide surfaces fixed to the outermost two large-diameter support plates 3 on the outer peripheral surface of the outermost two large-diameter support plates 3 fixed to the detached village 2. The large-diameter support plate 3 is fixed to the machine frame by an appropriate method so that the surface that first contacts the large-diameter support plate 3 as the conveyor advances becomes a traversing slope surface. At this time, when the guide piece 101 is not in contact with the large-diameter support plate 3, the suction port 7 of the suction tube 6 is at the position where it should almost touch the lower surface of the egg 1 at the egg position, and the guide piece 10 The position of the guide piece 10 and the shape of the guide surface are such that when the large-diameter support plate 3 is in contact with the top of the chevron, the suction port 7 of the suction tube 6 is located below the small-diameter support plate 4. Set. In the second embodiment, when washed bran eggs are transferred on an egg tray, the two large-diameter support plates 3 on the long outside of the shaft punch 2 are moved to the guide piece 10 by the progress of the conveyor, as shown in FIG. Upon contact, the conveyor detachment 2 is lifted upward according to the gentle upward slope of the guide surface, and as shown in Figure b, the conveyor detachment 2 is lifted near the area where the large-diameter support plate 3 crosses the mountain-shaped top of the guide surface.
The small-diameter support plate 4 fixedly installed passes above the suction port 7 of the suction pipe 6, and then the shaft village 2 of the conveyor descends downward according to the steep slope of the guide surface, and the large-diameter support plate 3 passes over the suction port 7 of the suction pipe 6. When the conveyor finishes descending the steep slope of the guide plate 10, the conveyor returns to its normal position as shown in FIG.

Other effects are the same as in the first embodiment. In addition, various known means are used as a mechanism for vertically moving the suction tube 6. For example, the suction tube 6 is fixed in a vertically movable state using a solenoid valve that is linked to a detector such as a microswitch or a phototube. Detecting when the egg receiver passes through the tube 6, the solenoid valve pushes the tube 6 down to a preset bottom dead center position, and immediately after the egg receiver passes, the suction port 7 is brought into a position where it should be almost in contact with the lower surface of the egg 1. Even if it is configured to restore, the same effects as in the previous embodiment can be achieved.

The present invention includes a conveyor that supports and transfers the surface of washed eggs at several points, a slit provided above the conveyor so that its longitudinal direction is approximately perpendicular to the conveyor, and that blows out high-speed air downward. An upward suction port is provided at a position below the conveyor corresponding to the egg transfer path and directly below the slit, or slightly closer to the direction of conveyor movement than directly below the slit.
When the eggs are above the suction port in the positional relationship between the conveyor and the suction device, the suction port approaches the conveyor until it almost touches the bottom surface of the eggs, and the eggs are sucked. By configuring the suction port to be separated below the conveyor when it is not above the mouth, the following effects are achieved. Since the eggs are transported by a conveyor, they can be processed continuously in the egg washing section, which is a front step, and the fan drying section, which is a back step.

A slit is provided above the conveyor, the longitudinal direction of which is almost perpendicular to the conveyor, and which blows out high-speed air downward.The slit is located below the conveyor, corresponding to the transfer path of the eggs, and slightly upward in the direction of conveyor movement than directly below the slit. A suction device with a closed suction port was installed at the bottom of the egg, and the suction port was set at a position where it should almost touch the bottom surface of the egg, so that the washing water adhering to the entire surface of the egg is washed away by the high-speed air from above around the bottom of the egg. This is an extremely short-distance device that blows down onto the surface of the egg, removes most of the water on the upper surface of the egg, and then suctions the adhering water that collects on the lower surface of the egg to remove most of the water on the lower surface of the egg. It is possible to almost completely remove adhering water on the entire surface of the egg. Since the egg is supported at only a few points, the outer surface of the egg is almost a free surface, and the blowing down of moisture by high-velocity air and the suction of moisture by vacuum suction are not hindered. . Regarding the positional relationship between the conveyor and the suction device, when the egg position is above the suction port, the suction port approaches the conveyor to the point where it should almost touch the bottom surface of the egg, and when the egg position is not above the suction port, the suction port approaches the conveyor. We installed a mechanism in which the mouth is separated from the bottom of the conveyor, so when the eggs pass over the suction port, the suction port almost touches the bottom surface of the egg, causing water to land on the bottom surface of the egg. When a conveyor component such as an egg tray passes over the suction port, it does not interfere with the passage of the egg tray, thereby eliminating damage caused by contact. Overall, it is possible to almost completely remove adhering water on the entire surface of eggs within an extremely short space of time, which contributes to considerably shortening the length of the fan drying section in the next process. This has the additional effect of increasing economic efficiency, including space.
