速に行うべきもので、除冷すると能率が悪いだけ
でなく、好熱細菌の活動を促す原因ともなるた
め、水を十分にかけて缶の外から急冷する。 Canned goods are manufactured using a mass production method, in which the cans are filled with food and drink such as meat, fish, fruit, fruit juice, etc. and sealed, then heat sterilized, cooled with cold water, and then drained. After that, the manufacturing date mark is printed and the product is packaged and shipped. The cans are continuously conveyed in a generally vertical position on conveyors installed across each process. Regarding heating canned foods, for example, mandarin oranges are heated at 80°C for 10 minutes. Canned food must be cooled quickly; gradual cooling is not only inefficient, but can also encourage the activity of thermophilic bacteria, so cool quickly from the outside by pouring plenty of water over the can.

つた。 However, if the water adhering to the surface of the cans is not completely removed after cooling, the manufacturing date mark will not be printed properly and there is a risk of serious quality defects such as rust forming on the surface of the cans that should be stored for a long time. However, in the conventional canning manufacturing process, this draining process was carried out as follows, which was extremely inadequate.

である。 After cooling with water, many small and large bead-shaped water droplets remain on the can surface, not only on the can lid but also on the can copper and the can bottom. While cans with water droplets are transported while standing on a conveyor, multiple tubes that introduce compressed air are installed close to the cans, air is blown out from the tips of these tubes, and the force of the air is used to drain the water. was going there.
However, in such equipment, since the action of the steam is carried out partially, it is not possible to remove water droplets over the entire surface of the can in a short period of time. In particular, the draining of the canopy was extremely inadequate. FIG. 1 shows an example of a canopy drainer, and shows the fumarole tube 2 viewed from the can lid 1b of the can 1. Fumarole A acts on the area B straight ahead of it, and some of the water droplets are scattered in the direction C, but
The water droplets that hit the seamed portion 3 of the can are moved in the direction from N to E while remaining attached to the can, and remain there.
上記の従来方法の水切りの工程では缶表面全体
にわたつて水切りを行うには、コンベヤーの長手

Most of the water droplets on the surface of the can are blown away, but the tiny water droplets that are attached to the can have a stronger adhesion to the can, so they remain and become tiny particles with a diameter of less than 1 mm. The water is broken down into small droplets, leaving countless small particles on the surface of the can. The water removed from the surface of the can scatters and falls along the inner wall of the housing 9 and is discharged from the drain pipe 26. In addition, small portions of the scattered water mix with air to create a humid atmosphere, so they are discharged to the outside of the housing 9 through the exhaust port 27. The exhaust port 27 is connected to a blower (not shown).

なつている。 Each can from which water droplets have been preliminarily removed in the first water droplet removal chamber A is subsequently carried into the second water droplet removal chamber B. This second water droplet removal chamber B is for completely evaporating fine water droplets on the can surface that could not be removed in the first water droplet removal chamber A, and has a slit nozzle group in its housing 28. However, this differs greatly in that the jet air flow in the first water drop removal chamber A is a high-speed air flow, whereas the jet air flow is a heating chamber air flow, and the general structure is that of the first water drop removal chamber A. It is similar to That is, in the approximate center of the second water droplet removal chamber B, a part of the pair of guide rails 8, 8' has a twisted part C' similar to the above-mentioned twisted part C, and the guide plates 8'', 8''. Similar guide plates 8, 8 are provided to form guide rail means for the second water drop removal chamber B. Furthermore, the levels of the pair of guide rails 8, 8' are changed in front of the twisted portion C' and in front and behind the twisted portion C', respectively. Also, although the number is different from that of the first water droplet removal chamber A,
Similarly to the first water droplet removal chamber A, a group of slit nozzles (downward blowing nozzles 32, 33, 34, 40, 35
and side blow nozzles 42, 42'; 43, 43';
44, 44'; 45, 45') are provided within the housing 28, each nozzle branching from a header box 50 which communicates via a duct 51 with a blower 52 and a heater 53. The housing 28 has a heat insulating structure to prevent internal heat from escaping.

Make sure to heat it to over 60℃. However, the temperature of the heated air needs to be set at a temperature that does not deteriorate the contents of the canned food, and is preferably set to less than 100°C. This is because if the conveyor were to stop for some reason during treatment with heated air, there is a risk that the temperature of the cans would rise to the temperature of the heated air.

いても同様に考えればよい。 In the above-mentioned embodiment shown in Figures 2 to 5, the canned food is handled by the guide rail means consisting of the twisted portions C, C' of the pair of guide rails 8, 8' and the guide plates 8'', 8.
Although the can is inverted by 180 degrees, it is not necessarily limited to the guide rail means for inverting the can; in short, it is necessary to ensure that the high-speed air flow and the heated air flow hit both the can bottom 1a and the can lid 1b. Bye. Therefore, modifications can be made as shown in FIGS. 6, 7, and 8, for example. Although FIGS. 6, 7, and 8 show the first water droplet removal chamber A, the second water droplet removal chamber B may be considered in the same manner.

訳である。 In FIGS. 6, 7, and 8, the same members as in FIGS. 2 to 5 are designated by the same reference numerals. In this modification of the guide rail means, the guide rails 8 and 8' do not intersect as in the previous example, but are arranged so that the canned food is almost horizontal.
After the guide rails 8, 8' are each twisted inward, they are twisted back to their original positions. Therefore, the canned goods 1 that are sequentially transported are at this twisted portion C.
At this time, the can lid 1b floats off the conveyor 5 into an approximately horizontal horizontal position, and then returns to its original position, that is, the position in which the can lid 1b is placed on the conveyor 5, making a rocking motion. However, in this modification, one guide plate 8'' shown in FIG.
The corresponding guide plate 55 is composed of a pair of divided guide plates 55', 55' separated from each other, and one side blowing slit nozzle 56 is provided between the pair of divided guide plates 55', 55', and the twisted portion At C, a high-speed air stream is injected toward the lid 1b of the canned food which is in a horizontal position. Therefore, can lid 1
This means that the entire surface of the can, including area b, is exposed to a high-speed air stream.

れる。 Moreover, the conveyor 5 shown in FIGS. 2 and 3 is
It consists of one conveyor that passes through the first water droplet removal chamber A and the second water droplet removal chamber B, but as shown in Figure 9, between the first water droplet removal chamber A and the second water droplet removal chamber B It may also be configured with a pair of conveyors 59 and 60 connected by. In this case, the first
The outlet end of the first conveyor 59 passing through the water droplet removal chamber A and the inlet end of the second conveyor 60 passing through the second water droplet removal chamber B are stacked next to each other,
Each can 1 conveyed by the first conveyor 59 is transferred onto the second conveyor 60 by a pair of auxiliary guide rails 61 and 62. According to one conveyor 5 shown in FIGS. 2 to 5, a large amount of water droplets deposited on the conveyor 5 is removed from the second water droplet removal chamber A in the first water droplet removal chamber A.
However, according to this modification, this does not occur and evaporation of the can surface in the second water droplet removal chamber B is promoted.

ことは行なわれていなかつた。 As described above, the present invention provides a first water droplet removal chamber A.
A high-speed air flow is used to remove most of the water droplets on the can surface, and the remaining water droplets are finely divided into second water droplet removal chamber B.
By using a structure in which the water droplets made into fine particles are evaporated by a heated air flow, the water droplets can be removed extremely efficiently. Thus, if the water droplets are not atomized as a preliminary treatment, the desired effect will not be obtained even if the same equipment is used to inject a stream of heated air. this is,
The can is made of thin metal with good thermal conductivity, and the surface of the can, which undergoes a rapid water cooling process, maintains the temperature of the contents at a relatively low temperature, e.g. 30°C to 40°C, which generates a heated air flow. This is because even if the water is sprayed onto water droplets, the temperature of the water droplets will not immediately rise and the water will evaporate. Therefore, in the past, special heating of the air stream has not been carried out in canning manufacturing equipment.

際に要請されている寸法である。 The running speed of canned goods on the conveyor line in the canning manufacturing process is typically 50 m/min, and with conventional, imperfect equipment, large water droplets with a diameter of 2 mm or more can be seen for 20 to 30 seconds or even before they can be seen. Moreover, the length of the equipment was 17 to 25 meters. On the other hand, according to the device according to the above embodiment, the length of the device is at most 5 to 7 meters, and it is possible to completely remove large and small water droplets from the can surface in an extremely short period of about 6 to 8 seconds. be. The length dimension of the above device is the dimension actually required in the conveyor line of the can manufacturing process.

である。 Currently, we are using a device with a length of 7 m to remove water droplets from the can surface.
If the temperature of the canned food is 30°C to 40°C when the canned food is transported into the first water droplet removal chamber A within 8 seconds, the high-speed air flow in the first water droplet removal chamber A will be at a wind speed of 100 m. /sec or more, preferably 120m/sec or more. In this case, the residual water droplets on the can surface become fine particles with a particle size of less than 1 mm. If the wind speed is lower than that, the residual water droplets on the can surface will not become fine enough.
For example, at wind speeds of about 30 to 50 m/s, particle sizes of 2 to
Many 5mm water droplets remain. High-velocity airflow works well at room temperature and does not require special heating. Further, the heated air flow in the second water droplet removal chamber B needs to have a temperature of 60° C. or more, preferably around 90°, and a wind speed of 30 m/sec or more.
