Description

[Detailed Description of the Invention] The present invention relates to a sterilization device for pickles that are hermetically packaged in a synthetic resin packaging bag.

Conventionally, when packaged pickles are shipped from a factory as a product, in order to prevent bacteria from growing inside the sealed bag between the time the product is shipped and purchased by the consumer, Immediately before shipping, packaged products are generally immersed in boiling water to sterilize them in hot water to kill germs inside.

A conventional apparatus for carrying out this type of sterilization process has a hot water storage tank installed in the upper part of the apparatus, and the sterilization process is carried out using boiling water while the packaging table is transported by a sterilization conveyor installed in the tank.

In this case, a floating holding conveyor for packages is provided above the sterilizing conveyor in the tank, and the holding conveyor is used to prevent the packages sent into the tank via the sterilizing conveyor from floating to the surface in the boiling water. It is constructed so that it can be properly pressed down and passed through boiling water.

By the way, the packaged products fed onto the sterilization conveyor are continuously fed from a bagging machine outside the machine, so
It is not guaranteed that each item will be correctly arranged on the conveyor,
Sometimes several pieces are placed on top of each other.

When several bags are fed in this way, each bag is brought into contact with the floating presser conveyor while still overlapping each other and is moved to the end of the conveyor, so hot water is applied to the overlapping parts of the bags. There was a problem in that the heating effect was not sufficiently applied, and therefore sufficient sterilization could not be carried out.

Of course, if the sterilization treatment is insufficient as described above, it goes without saying that residual bacteria will proliferate after shipment, which will adversely affect the quality of the pickles.

The purpose of this project is to solve the above-mentioned problems of conventional sterilizers, and to provide a sterilizer that can sterilize all packaged items in boiling water at an even heating temperature. In order to ensure uniform sterilization, the packaged items are vibrated in the boiling water by blowing air bubbles into the boiling water sterilization tank, allowing the packaged items to move around in the hot water and receive the temperature evenly. It is characterized by:

Next, the sterilizer according to the present invention will be described in detail with reference to the illustrated embodiment. FIG. 1 is a plan view, FIG. 2 is a sectional view, and as shown in FIG. A cold air drying chamber 3 is provided below the tank 2.

The boiling water sterilization tank 2 has a conveyor 5 for sterilizing the packaged products 4 and a float holding conveyor 6 for allowing the packaged products 4 to move in the hot water without floating. Second
The materials are sequentially and continuously fed onto the sterilizing conveyor 5 from the feeding device 7 above the starting end of the sterilizing conveyor shown at the right end of the figure.

A fan 8 is provided above the left end of the sterilization conveyor 5 to remove hot water adhering to the surface of the packaged product 4 and return it to the sterilization tank 2.

A plurality of pipes 10 each having a large number of bubble jetting nozzles 9 are installed in the lower part of the hot water sterilization tank 2, and an air supply blower for feeding air into the pipes 10 is installed outside the tank.
11 is provided, and air sent from the blower 11 causes bubbles to be continuously ejected from the bubble ejection nozzle 9 into the hot water in the tank, and the packaged product 4 being transferred through the hot water is swayed by the bubbles. It looks like this.

The cold air drying chamber 3 is partitioned from the upper part of the device where the hot water sterilization tank 2 is installed via a partition wall 12, and by a drive chamber 14 at the bottom of the device and a partition wall 13, and a cooling air supply device (described later) is installed at one end of the upper portion. A cold air outlet 15 is provided for sending the cold air sent from 23 into the room, and a cold air intake port 16 is provided below the lower partition wall 14.

Of course, the upper partition wall 12 has a drop opening 17 below the end of the sterilization conveyor 5 for dropping the packaged product 4 into the cold air drying chamber 2, and the lower partition wall 14 has a drop opening 17 at the lower end of the sterilization conveyor 5, and the lower partition wall 14 has a drop opening 17 at the lower end of the sterilization conveyor 5. They each have an opening 18 between them for guiding cold air to the suction port 16.

Inside the cold air drying chamber 3, packaged products 4 are placed along the length of the chamber.
A plurality of cooling conveyors 20. ．． 20□, 203, . . . are provided in a stepped manner so as to overlap in the vertical direction.

These cooling conveyors 20. ．． 202, 20. ...
. . . are all driven in opposite directions in a vertical relationship, and except for the bottom conveyor 204, gaps 21 for dropping the packaged products 4 are provided between one end and the side wall 19 alternately. It is constructed so that it can be installed.

One end of the cooling conveyor 204 at the lowermost stage extends outside the side wall 19, so that the cooled and dried packages 4 are sent out of the machine.

The cold air suction port 16 provided at the bottom of the cold air drying chamber 3 is connected via a duct 22 to a cooling air supply device 23 provided on the side of the aircraft body, and from the device 23 is connected to another duct 24.
are connected to the cold air outlet 15 so that the cooling air circulates through the device 23 and the cold air drying chamber 3 through the respective ports 15 and 16.

In the figure, 25 is a motor for driving the conveyor.

The sterilizer according to the present invention has a large number of bubble jetting nozzles 9 in the lower part of the hot water sterilizing tank 2 that can jet air sent from the air supply blower 11 outside the tank into the hot water, as described above.
The packaged product 4 is vibrated by the bubbles ejected while being transferred through the tank and moves around in the hot water, so that the entire surface of the packaged product can be uniformly exposed to the temperature of the hot water.

In addition, when multiple packaged items are fed into the tank in a state where they are stacked on top of each other, each packaged item will be separated from each other by being subjected to the rocking action as described above due to the ejected air bubbles, and each packaged item will be separated from the other by being subjected to the rocking action as described above. Since the particles move around inside, the surrounding surface can be heated evenly, and appropriate sterilization can be performed.

Furthermore, since the packaged product is repeatedly exposed to air bubbles, it can also receive a cleaning action in which dirt and the like adhering to the surface of the bag are removed.

Therefore, according to this sterilizer, the packaged items can be transferred inside the boiling water sterilization tank without being in a stationary state as in conventional sterilizers of this type, so it is possible to equalize the heating state for each packaged item. This has the advantage of shortening the transfer time in the thermal field, as well as the ability to clean the surface of the packaged items, as well as making the sterilization temperature uniform for all packaged items, allowing for even sterilization. So,
It has the advantage that the ripeness and taste of the product can be made uniform, and good quality with a long shelf life can be obtained.
