Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a high-pressure sterilizer that continuously heat-sterilizes and cools canned goods, bags, etc. in a high-pressure tank.

Conventionally, in the case of continuous heat sterilization and cooling of processed products such as canned goods and bagged products while transferring them in a high-pressure tank, the means for transferring the processed products was to transfer the processed products from the cooling water in the cooling chamber to the air above it. Normally, the material to be treated is transferred from the gas phase of the heating chamber into the heated water.In this method, the transfer path of the treated material is bent and detoured, making the transfer mechanism complicated. There are also drawbacks such as the transfer action is not smooth and the driving power is also large.

In order to improve this defect, the applicant first created an intermediate chamber between the cooling chamber and the heating chamber with a pair of partition walls, and the process was carried out through transfer holes provided oppositely under the liquid surface of the partition walls. To directly transfer materials from cooling water to heated water and to return the liquid overflowing into the intermediate chamber to each chamber using a pump, thereby simplifying the transfer mechanism, smoothing the transfer action, and reducing driving power. developed.

(Refer to Hakama Kaisho No. 52-451) However, this method not only requires a pump device to return the heating liquid and cooling liquid that overflow from the transfer hole to the intermediate chamber to the respective chambers, but also requires a pump device to return the heating liquid and cooling liquid that overflow from the transfer hole to the intermediate chamber. If the amount is increased, there is a problem in that the pump sucks in air and the circulation and reflux action of the overflow liquid is hindered.

Furthermore, in any of the above-mentioned systems, the quality of the processed material is affected because the processed material is directly transferred from the cooling liquid to the heated liquid or from the heated liquid to the cooled liquid.

Taking advantage of the current state of affairs, the present invention further improves these conventional deficiencies by dividing the inside of a high-pressure tank with a plurality of partition walls to create a cooling chamber for storing cooling liquid and a heating chamber for storing heated water. The gist is that a partitioned mixing tank is formed in between, transfer passages are provided in the walls of each section facing each other under the liquid level, and a transfer device for transporting the processed material into and out of the high-pressure tank is inserted and rearranged in this transfer rock. It is something to do.

To explain an embodiment of the present invention with reference to the drawings, a high-pressure tank 2 which is sealed and maintained at high pressure inside by a pressurized air supply pipe 1 has two or more, preferably four, compartments approximately in the center. Walls 3, 3... are provided, and the high-pressure tank 2 is divided into a cooling chamber 4 for accommodating cooling water at the front, a heating chamber 5 for accommodating heated water at the rear, and a partitioned mixing tank 6 at the middle. It is heated, circulated, and refluxed by a circulation pipe 9 having a heating pump 7 and a heating device 8 housed in the heating chamber 5.

In the partition walls 3, 3, respectively, a pair of upper and lower holes or short cylindrical transfer passages 10, 11 are provided at the same height position below the surface of the heating water and cooling water. The forward end of the high pressure tank 2 is located below the liquid level of the cooling chamber 4 and has its tip connected to an open water tank 12, and has the transfer path 1.
A pair of upper and lower transfer tube passages 13 and 14 having a rectangular cross section are formed protrudingly on the same straight line as 0 and 11.

The open water tank 12 and the cooling chamber 4 are connected by a circulation pipe 17 having a water supply pump 15 and a cooling device 16, so that the cooling water overflowing into the open water tank 12 from the transfer pipes 13 and 14 of the cooling chamber 4 is cooled and circulated. It is configured as follows.

A transfer device 18 for transferring the processed material into and out of the high-pressure tank 2 includes a driving chain wheel 19 installed at the top of the open water tank 12 and a chain wheel 2 installed at the top and inside of the open water tank 12 as well as inside the heating chamber 5.
0, 20, 20, 2 A pair of left and right inorganic transfer chains 21, 21 suspended from each other, a transfer attachment 22 installed between these transfer chains, and a porous I-type retainer 23 that can be opened and closed to accommodate the processed material. The pair of endless transfer chains 21, 21 are sequentially connected to the drive chain wheel 19, the open water tank 12, the transfer channel 13, the liquid phase of the cooling chamber 4, and the transfer channel. 10. The liquid phase in the partitioned mixing tank 6 passes through the transfer path 10, the liquid phase in the heating chamber 5, reaches the chain wheel 2, and then further transfers to the transfer path 11 and the partitioned mixing tank 6.
liquid phase in the transfer path 11, liquid phase in the cooling chamber 4, transfer tube path 14,
It is placed on a rack so as to return to the drive chain wheel 19 via the open water tank 12, and in particular, the transfer stubs 13 and 14 are guided by guide grooves 25 provided inside them.

The transfer attachment 22 supported between the transfer chains 21 and 21 has a rectangular shape that is substantially the same as the cross section of the transfer tubes 13 and 14, and is formed smaller at each end.
3, 14 are attached to the transfer chains 21, 21 at intervals so as to divide them into a plurality of sections, preferably 5 to 7 sections. Further, a box-shaped retainer 23 is integrally provided on one side of the transfer attachment 22, and the transfer attachment 22 serves as a part of the retainer 23, and the other side excluding the transfer attachment 22 is provided integrally with the transfer attachment 22. A large number of holes are formed in the container, and a lid 26 that can be opened and closed is provided so as to be able to be locked freely, so that the processed material can be stored inside.

Note that the transfer attachment 22 does not necessarily have to be formed integrally with the retainer 23, but can be formed separately.

Next, the guide 24 guides and supports the transfer attachment 22 and the lower part of the retainer 23 through the transfer pipe 13,
14 and the transfer paths 10 and 11.

Since the embodiment of the present invention is configured as described above, water is stored in the high-pressure tank 2, the inside is made to have a high pressure, and the water in the heating chamber 5 is heated to, for example, 130 qo by the heating device 8.
Furthermore, if the water in the cooling chamber 4 is maintained at, for example, 30°C, the temperature of the water in the cutting mixing tank 6, which is suitable for both chambers and the transfer passages 10 and 11, will be the same as that of the water in the high-pressure cooker, as shown in Figure 1. When separated by , it is kept between 50 and 90.

Therefore, when the opening/closing lid 26 is opened and closed in the vicinity of the drive chain wheel 19 and the processed material to be heated and sterilized is stored in the retainer 23 and transferred, the retainer 23 is connected to the pair of transfer chains 2
1 and 21, it enters the liquid phase of the cooling chamber 5 from the open water tank 12 through the transfer tube 13, passes through the transfer path 10, is preheated in the liquid phase of the partitioned mixing tank 6, and then exits the transfer path 10. It enters the liquid phase of the heating chamber 5, goes around the chain wheel 20 while being heat sterilized, enters the liquid phase of the partitioned mixing tank 6 from the transfer path 11 again, is pre-cooled here, and then passes through the transfer path 11 and enters the cooling chamber 4. After being completely cooled in the liquid phase, the material is sent out through the transfer tube 14 and the open water tank 12 to the outside of the open water tank, so the lid 26 is opened to take out the processed material.

However, during the transfer action of the lever, the cooling water flows out from the front end of the transfer tubes 13, 14 into the open water tank 12 due to the pressure difference, but the transfer attachment 22 transfers the inside of the transfer tubes 13, 14 in a state where it is divided into a plurality of sections. Therefore, the pressure inside the high-pressure tank 2 is reduced step by step, and the amount of liquid overflowing from the transfer pipes 13 and 14 is also reduced, and only this overflowing amount of liquid is transferred to the pump 1.
While being cooled in step 5, it is returned to the cooling room 4.

The present invention divides the inside of a high-pressure tank with a plurality of partition walls to form a partition mixing tank between a cooling chamber and a heating chamber, and each partition wall has holes or short cylinders facing each other below the liquid level. A shaped transfer path is provided, and the processed material is transferred in a straight line between the cooling chamber and the heating chamber via this transfer path, so there is no need for a pump device as in the conventional linear transfer method, The transfer mechanism can be further simplified, and the mixing of the cooling liquid and heating liquid from the transfer path in the partitioned mixing tank practically causes almost no problem in reducing the heating efficiency of the heating chamber and the cooling efficiency of the cooling chamber. Not only is this within the range, but the mixed liquid in the partitioned mixing tank must be pre-heated when the processed material is transferred to the cooling chamber, and pre-cooled when the processed material is transferred from the heating chamber to the cooling chamber. It has an excellent feature of preventing rapid heating or cooling of the processed material and thereby preventing the quality of the processed material from deteriorating.
