BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic desalination pressing method as a pretreatment for seasoning vegetables that have been salted and preserved.

[0002]

2. Description of the Related Art Conventionally, a desalting and pressing step as a pretreatment for seasoning vegetables that have been salted has been moved to a pressing device after completion of desalting, which is a separate apparatus. .

[0003]

As for conventional desalination, a method of performing salting material in a container while repeating running water and water replacement, a method of attaching a stirring device to the container and repeating running water replacement to desalinate, or a container For example, a method of sending bubbles into the inside for desalting was used.

However, desalination by simply repeating running water and water replacement not only takes a long time, but also causes uneven desalination. In addition, in the case of single salt pickling such as cucumber, it cannot be used with stirring for desalting and it cannot be used. This desalting by stirring was suitable only for cuts such as Fukugami pickles. . Furthermore, when air bubbles are sent into the container, bacteria are likely to be generated and mold, etc., and foreign matter such as sand is rolled up in the material washed by the air bubbles and cannot be removed by mixing again in the material. was there.

Regarding the squeezing after desalting, the pickled material is put into a container manually or by a belt conveyor and squeezed by a hydraulic press, but it cannot be squeezed uniformly and the squeezed weight is accurately measured. There were drawbacks such as not being able to.

[0006]

[Means for Solving the Problems] Therefore, the restoration rate of the material (the rate of the absorbing liquid and the return of the shape) becomes uneven, and there is a waste of producing a large amount of seasoning liquid for seasoning and discarding the residual liquid. It was Furthermore, since it is managed manually, automatic driving was impossible. The Applicant has conducted extensive research to solve the drawbacks of the conventional desalination and squeezing, and as a result, the desalination process and the squeezing process are performed by one device, and an automatic control device is provided. Precisely squeezed weight is accurately and automatically measured and controlled to enable fully automatic operation, so work can be performed even at night, and the squeeze ratio is input based on the data for each different product. Even inexperienced people can work safely and accurately.

[0007]

[Function] The salted material for pickling is put into the rotary drum (1) and pressurized in the desalting tank (5) to squeeze water having a high salt concentration in advance, and further supply water,
The rotating drum (1) is rotated normally and inverted while repeating the water exchange to stir the materials in the drum to desalt. Then, when draining, pressure is applied to squeeze out the salt remaining inside, and this step is performed in 3 to 4 steps.
Repeat times. At this time, foreign matters (cucumber seeds, cuttings, sand, etc.) in the drum are discharged from the drum, and once discharged, there is a cleaning effect without entering the drum again, and the finished product is good. .

After the desalination, the rubber sheet (4) is expanded and compressed under pressure, the pressure is reduced and the drum (1) is rotated to loosen the mass of the material, and further compressed under pressure to the designated weight. When automatically squeezed and squeezed to reach the specified weight, the operation is automatically stopped. In the squeezing according to the method of the present invention, the squeezing is made uniform by repeating the inversion of the drum (1) after pressurization to loosen the solidified material, and the seasoning liquid permeates evenly during the pickling after taking out and the restoration ratio. egoism,
It has a natural shape and looks good.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the drawings, A is a cylindrical rotating drum, and a large number of small holes (1) for water permeation are provided on a half circumferential surface of this rotating drum A. A raw material inlet (5) is openably and closably provided at the center of the peripheral surface of the rotary drum A where the water permeable small hole (1) is provided. The peripheral surface (2) on the opposite side of the half surface having the small holes (1) is a dark surface without small holes. Rubber sheet (3) on the inner surface of this dark side
Is installed to form a rotary drum, and the rotary drum A
A semicircular cylinder is concentrically provided on the outer side of the tank with a demineralization tank (6) mounted on the rotary shaft (7). Further, the raw material inlet (5) of the rotary drum A of the desalination tank (6)
The drainage port (9) is provided at the central position on the side opposite to. And this whole device is mounted on the automatic weighing machine (8).

Reference numeral B indicates an automatic control device. This automatic control device stores commands such as drum rotation, squeezing, water supply / drainage, and automatic weighing. The squeezing weight is commanded to the automatic weighing machine (8) in the squeezing process. The operator should monitor it by setting a suitable compression ratio according to the type of pickle to be produced, such as 65% by weight, 70% by weight for material b, and 75% by weight for material c. Instead, only when the automatic control device B is instructed, the pressure squeezing in the tram (1) is performed, and when the squeezing is performed to a percentage of the instructed pressure, the squeezing of the drum is automatically stopped and the material is squeezed. Complete.

Therefore, the pickled raw material which has been salted and stored is introduced into the rotary drum A through the raw material inlet (5), and only the rotary drum A is inverted to position the rubber sheet (3) above and dehydrate in advance. Then, the concentrated salt water is dehydrated, water is then put into the tank (6), and air is sent between the rubber sheet (3) and the inner peripheral surface of the tank to expand the rubber sheet (3). Squeeze the salted ingredients. Reference numeral (4) in the figure indicates a stopper for the rubber sheet (3).

Therefore, the water in the desalination tank (6) is infiltrated into the raw material through the water-permeable small hole (1) provided in the peripheral surface of the rotary drum A for desalination, and the water is further replaced. Desalting is repeated to completely desalt the raw material and drain water from the drain port (9).

After the desalination, the drum (1) is rotated to loosen the solidified material, the rubber sheet (4) is expanded and compressed under pressure, the pressure is reduced and the drum (1) is rotated to rotate the material. Squeeze out the lumps and press and squeeze again to give the specified weight%
The operation is automatically stopped when the weight set by the controller is reached while automatically weighing up to. In the squeezing according to the present invention, after the pressing, the drum (1) is rotated to loosen the solidified material so that the squeezing becomes uniform, and the pickled liquid is absorbed well in the seasoning liquid when pickled after being taken out.

INDUSTRIAL APPLICABILITY The present invention uses the same device for desalination and compression, and eliminates the conventional work of carrying a raw material at a different place from the desalination device and compression device, and Since the salt is desalted by rotating the drum, sufficient desalination can be performed in a short time. In addition, in pressing, since the material that has been solidified is squeezed while rotating the drum, it is possible to obtain uniform pressing, the restoring force of the material is good, and a natural shape and uniform seasoning can be obtained. And shortening the working time can prevent the propagation of various bacteria.

In the method of the present invention, since the pressing ratio of the material can be measured and controlled by combining the automatic weighing machine and the automatic control device, not only uniform pickles can be obtained, but also automatic operation at night is possible. It has an outstanding and epoch-making effect not seen in conventional pickle production.
