Detailed Description of the Invention (Field of Industrial Application) The present invention is a high-speed desalination sterilization device that can efficiently lower the chlorinated salted materials such as pickles and side dishes in a short time and sterilize them at the same time. Regarding.

(Prior art) Storing general pickles, prepared foods, fish and shellfish at high concentrations is an indispensable condition for maintaining the quality of these pickles, especially vegetables. It is common practice to collect large quantities at certain times of the year, store them in salt, preserve them for a long period of time, and desalinate them as needed. Storage at such a high salinity level is a necessary condition for protecting the color tone of the raw materials and maintaining the quality of the quality of the raw material.When commercializing this salted material, it must be desalted as soon as possible to reduce the salt content. Furthermore, sterilization work is required to prevent germs.

Therefore, conventionally, when commercializing this type of salted material, these operations, namely desalination and heat sterilization of the salted material, are performed using completely separate equipment. .

(Problems to be Solved by the Invention) For this reason, when conventional desalination and heat sterilization are performed in separate devices, a large space is required to install the desalination device tΣ and the sterilization device. However, since a desalination device and a sterilization device are each required, equipment costs increase, and the work of transferring the contents from the desalination device to the sterilization device is complicated and troublesome. Since they were performed separately, there was a problem in that the work took a long time and caused an increase in costs.

Therefore, the present invention has been made to solve the above-mentioned problems of the conventional art, and allows desalination and 'B bacteria to be carried out simultaneously in one device, thereby greatly reducing the installation space of the device, and To provide a high-speed desalination sterilization device that can reduce costs, eliminate the work of transferring contents from a desalination device to a sterilization device, shorten working time, and at the same time reduce costs by improving work efficiency. The purpose is to

〔Example〕

Hereinafter, one embodiment of the present invention will be described based on the accompanying drawings.

1 and 2, l is a substantially box-shaped aquarium tank with an open top and made of a material with excellent corrosion resistance such as stainless steel, which is attached to a support frame 2 erected on the ground. A cylindrical rotary tram 3 with both ends closed is accommodated in the aquarium tank l, and this rotary tram 3 is connected to both side walls 1a, la of the aquarium tank 1 through bearings 5.5 by means of a hollow central shaft 4 in a watertight state. It is rotatably supported. The outer peripheral wall of the rotating drum 3 is made of punched metal made of a corrosion-resistant material with a large number of small holes 3a, and a spiral plate 6 serving as a stirring member is integrally formed on the inner surface of the rotary drum 3 over almost its entire length. is formed. An input/discharge port 3b is provided on the cylindrical outer peripheral wall of the rotating drum 3 at one end (left end in Figure 1) for inputting and discharging salted raw materials such as pickles and side dishes. The exit 3b is opened and closed by a sliding door 7.

One end (the right end in FIG. 1) of the center shaft 4 of the rotating tram 3 is connected to a shaft coupling 12 to the rotating shaft (not shown) of a deceleration motor 11 as a drive source attached to a bracket 10 fixed to the support frame 2. The deceleration motor 11 can be rotated in forward and reverse directions and has a continuously variable speed of f7. An ejector 15 is connected to one end of the central shaft 4 of the rotating drum 3 via a rotary joint 13 and a reverse valve 14, and this ejector 15 has one inlet 15a connected to a water supply tank or a water supply source of a water faucet ( (not shown) and is connected to a steam supply source (not shown) at the other inlet 15b,
Ejector 1 ejects water from the water supply source and steam from the steam supply source.
5, and this mixed water is sent to the reverse valve 14 and the rotary joint 13.
．． and the other end (first
It is supplied to the hollow inner cylinder 4b at the center fd+4 through the axial passage 4d (left end in the figure), and from there it is ejected into the rotating drum 3 through a number of through holes 4C bored in the peripheral wall of the central shaft 4. It has become.

A water supply pipe 17 connected to a water supply source via an on-off valve 16 and an overflow vibe 18 are provided at the upper part of one side of the aquarium tank l.
In addition, an outlet 1c is provided in the bottom wall 1b of the aquarium tank 1, corresponding to the input/discharge port 3b of the rotary drum 3. The bottom cover 2 slides along the guide rail 19 provided.
The bottom wall 1b of the aquarium tank l is inclined downwardly toward the outlet. In addition, a train vibe 21 with an on-off valve is connected to the bottom M20, and a water tank l
At the bottom of one side is a drain pipe 23 with an on-off valve 22 that extends horizontally.
is connected.

Note that 24 is a seal between the side wall 1a of the aquarium tank l and the center shaft 4, and 25 is a gasket provided around the outlet 1c of the bottom wall 1b of the aquarium tank l.

In the above configuration, in order to perform desalination stone and sterilization of salted raw materials such as pickles and side dishes that have been pickled in a strong state in advance,
First, with the deceleration motor 11 stopped, the drum 3 rotates once.
Slide the opening/closing door 7 in the axial direction to open the input/discharge port 3b, and from there the salted raw materials (not shown) such as the above-mentioned pickles and side dishes are poured.
is put into the rotating tram 3, and the opening/closing door 7 is closed.

Then, water and steam coming from a water supply source and a steam supply source (not shown) are supplied to the ejector 15 and mixed, and the check valve 14
The mixture of water and steam is guided into the hollow inner cylinder 4b of the central shaft 4 in the rotary tram 3 through the single-rotary joint 13 and the axial passage 4a at the left end of the central shaft 4 of the rotary tram 3, from where the mixture of water and steam is passed through the central shaft 4 of the rotary tram 3. The hot water is ejected into the rotating drum 3 toward its outer circumference through the numerous through holes 4C of the shaft 4, and hot water at an appropriate temperature (preferably 60°C to 70'C) is generated within the rotating drum 3. This hot water flows out from a large number of small holes 3a in the outer circumferential wall of the rotating drum 3 into the aquarium tank l on the outside thereof. At this point, the deceleration motor 11 is activated and 1. The center shaft 4 and the rotating drum 3 are rotationally driven through the shaft joint 12.

Since a spiral blade 6 with a right-handed thread is formed on the inner surface of the rotating drum 3, for example, when the central shaft 4 is rotated counterclockwise when viewed from the deceleration motor 11 side in FIG.
The salted raw material (not shown) in the rotary tram 3 is stirred together with hot water by the spiral plate 6, and while rotating, the first
It is transported to the right side in the figure. Therefore, when the rotation of the deceleration motor 11 is reversed, the salted raw material accumulated on the right side of the one-rotation tram 3 is not stirred by the spiral plate 6, so it rotates in the opposite direction.
That is, it is transported to the left in FIG. Therefore, by switching the rotational direction of the deceleration motor 11 at appropriate time intervals, the salted raw materials can be dispersed and circulated approximately evenly within the rotating drum 3, and while being stirred together with the hot water, desalination can be carried out evenly and efficiently, and sterilization can be carried out at the same time. can be done.

At this time, the mixture of water and steam may be supplied from the ejector 5 to the rotating drum 3 constantly in order to increase desalination and sterilization efficiency, or intermittently in consideration of economic efficiency. good. Note that the hot water overflowing from the aquarium tank l is discharged to the outside from the overflow vibe 18.

To take out the salted raw materials in the one-rotation drum 3 after desalination and sterilization, first open the on-off valve 22 at the lower left side of the aquarium tank l and drain the salted raw material from the drain pipe 23 into the aquarium tank 1. After discharging the hot water to the outside, the opening/closing door 7 of the rotary tram 3 and the bottom 20 of the water tank l are opened, and the rotary tram 3 is moved by the deceleration motor 11 to the deceleration motor 1 as shown in FIG.
When the rotary drum 3 is rotated slowly around the rotary drum 3, the salted raw material accumulated in the lower part of the rotary drum 3 is conveyed to the left side of the rotary drum 3 in FIG. 3b and the bottom 2220 into a packet (not shown) disposed below the aquarium tank l.

By the way, the reason why boiling water is generated by mixing steam and water as described above is that if only steam is used, the raw material for salting will be easily damaged by high heat, and if boiling water is used from the beginning, it will be necessary to use a rotating drum from the boiling water supply source. This is because a pressure-feeding pump or the like is required to supply hot water into the interior of the hot water tank, which increases costs.

Furthermore, if the bottom part 1b of the aquarium tank l is tilted toward the outlet IC as shown in Figure 1, sand and gravel attached to pickles, etc. accumulated on the bottom wall 1b of the aquarium tank l can be easily removed. The outer peripheral wall of the rotary drum 3 may also be tilted toward the input/output port 3b for the same purpose, although not shown, for convenience in cleaning operations and the like.

In the embodiment, the spiral blade 6 is provided on the rotating drum 3, but the spiral blade 6 may also be provided on the outer periphery of the central shaft 4, or instead of the spiral blade 6, a large number of rod-like protrusions for stirring may be provided. It may be formed on the inner surface of the rotating drum 3 or on the outer peripheral surface of the central shaft 4.

Furthermore, if a lid is attached to the open upper surface of the aquarium tank 1, side dishes can be boiled. In this case, since no pressure is applied inside the aquarium tank l, the lid only needs to be placed thereon.

(Effect of 51 Ming) The high-speed desalination sterilization device according to the present invention has the configuration and operation described above, and desalination and 11V
4 at the same time, it is possible to significantly reduce the installation space of the equipment compared to conventional equipment, and also to significantly reduce equipment costs. Since there is no need to transfer the contents, the work time can be significantly shortened, and at the same time, work efficiency is significantly improved.As a result, the quality of salted products such as pickles is maintained without damaging the color tone of the raw materials and maintaining crispness. This has the effect of not only making it constant, but also reducing the cost of the product.
