Abstract

PURPOSE:To rapidly carry out desalting and cleaning without impairing a product to be cleaned, by desalting and cleaning the product to be cleaned subjected to dry return in a permeation tank using a cleaning tank equipped with an ultrasonic vibrator and foam generator. CONSTITUTION:A product to be cleaned is thrown into a permeation tank A packed with water, subjected to dry return and simultaneously attached product such as dust floated up is discharged and removed from an overflow tube 13 and then the product to be dried is sent into a cleansing tank B by driving a transferring device D. 20-60KHz frequency is then applied to supersonic vibrators 1 arranged in the circumferential wall and bottom face of the tank B to provide supersonic vibration to the product to be cleaned and simultaneously particle air or ozone is blown from a foam spraying nozzle 2 into the tank B to carry out separation of the attached dirt and desalting. The product to be cleaned is transferred through a transferring device D to a dehydration tank C, where the closing lid 10 of the tank is closed to seal the tank and air is sent from an aeration tube 11 to a tank C or the pressure in the tank C is reduced and the tank C is dehydrated.

Description

[Detailed Description of the Invention] <Industrial Application Field> This invention is a cleaning vt@ suitable for cleaning vegetables, dried foods, etc.
Regarding.

<Conventional techniques and problems> When cleaning raw vegetables, dried vegetables, fish and shellfish, dried salted fish, etc., it is necessary to immerse them in water for a certain period of time to re-dry them, and then desalinate them in a desalination tank equipped with a stirring station. , a method of cleaning with jet water was used.

However, in the conventional method as described above, it takes a long time to immerse and remove salt for drying, and the object to be cleaned is severely damaged. It has the disadvantage of causing uneven cleaning.

Means for Solving Problems〉 This invention provides a method for cleaning objects that have been dried back in a permeation tank.
It is characterized by rapid desalting, cleaning and dehydration using a cleaning tank equipped with an ultrasonic vibrator and a bubble generator 8Wl.

Function: The object to be cleaned is dried back in the osmosis tank and absorbed moisture, and the same effect is assisted by the cavitation effect of ultrasonic waves and the bubbles from the bubble generator to remove the object without damaging it. It salts and cleans quickly.

<Example> As shown in the attached drawings, this invention consists of a penetration tank A1, a cleaning tank B, and a dehydration tank C. The penetration JaA, the cleaning tank B1, the cleaning tank B, and the dehydration tank C are used for transporting objects to be cleaned. Continuously carried out by equipment.

Washing tank A is for the purpose of pre-treatment by soaking salted dried fish, dried vegetables, etc. to absorb water. Materials such as metal plates and synthetic resin plates are used. The following cleaning action can be performed more effectively by using a ceramic plate or a ceramic-coated tank that is activated with a weak alkali.

Cleaning tank B has the required number of ultrasonic vibrators 1 and bubble blowing nozzles 2 mounted on the peripheral wall and bottom of the tank, and the frequency can be arbitrarily controlled in the range of 20 to 60K (not shown). The ultrasonic vibrator 1 is activated by the output of the ultrasonic vibration generator, and ultrasonic vibrations are applied to the object to be cleaned through the water in the tank.

The bubble blowing nozzle 2 is composed of a known sprayer or a nozzle having the same effect, and blows air or ozone generated by an ozone generator into the water in the tank as particulate bubbles using a pump.

In the dewatering tank C, a support shaft 6 is rotatably fixed to a support frame 5 with wheels 4 running on a track 3, and a semi-geared wheel 7 provided outside the tank is rotated and tilted by a drive wheel 8, and A lifting mechanism 9 provided at both ends of the shaft is provided with a hermetic lid 10, and a ventilation pipe 11 for pressurizing or depressurizing the inside of the tank is provided.

The above-mentioned infiltration tank A1 and washing tank B are provided with a water filler tap and an overflow pipe 13 for discharging floating matter, and a drain pipe 16 equipped with a remote-controlled electromagnetic on-off valve 15 at the bottom, as well as a drain pipe 16 for passing the objects to be cleaned. A porous filter plate (not shown) or the like is provided as appropriate to prevent dust and dirt from passing through.

In the figure, reference numeral 17 denotes a transfer device port for the object to be cleaned, an ultrasonic generator, a pump for pumping air, ozone, etc. to the bubble blowing nozzle 2, a pressurization or depressurization pump for dehydration of the dehydration tank C, and a dehydration tank sealing I. ! This is a control panel for remotely controlling the elevating mechanism that raises and lowers 15.

This invention has the above-mentioned configuration, and when the object to be cleaned is salt-dried fish, the salt-dried fish is put into the soaking tank A filled with water and immersed, and the salt-dried fish absorbs water and is returned to dryness. At the same time, dust and other deposits that float to the surface are removed by supplying water and discharged from the overflow pipe 13, and after being immersed for a certain period of time, the transfer device port is driven to send the salted and dried fish into the washing tank B.

Ultrasonic vibrations are applied to the dried salted fish pretreated as described above and transferred to the water in the cleaning tank, and air bubbles are blown into the water from the air bubble injection nozzle 2.

This ultrasonic wave applies minute vibrations to the salt-dried fish and removes dirt adhering to the surface, and the air bubbles are also destroyed by the impact of the ultrasonic vibrations, creating a stirring action in the minute range around the air bubbles, resulting in river sonic vibrations. Cleaning and desalination are efficiently carried out by the synergistic effect of the cleaning action of the water and the heterogeneous cleaning action of the local movement of water.In particular, when air bubbles are used together, the water movement caused by the destruction of the air bubbles cleans the object to be cleaned. Since the water is agitated, there is little unevenness in cleaning, and the separation of adhering dirt and desalting can be done quickly and reliably.

In this way, light dirt and dust separated from the salt-dried fish float to the surface and are discharged by overflow from the water supply, while heavy dirt and dust settle to the bottom, so the solenoid valve 1 of the discharge pipe 16
Listen to step 5 and drain it with water.

Note that the frequency of the ultrasonic wave is appropriately selected depending on the type of the object to be cleaned.

The dried salted fish washed and desalinated in this way is transferred to the dehydration tank C using a transfer device, and after being sealed with an airtight lid 10, air is sent into the tank for ha pressure dehydration, or the air in the tank is exhausted. After dehydrating under reduced pressure, the water accumulated at the bottom is discharged from the drain pipe 16, the airtight lid 10 is opened, and the tank C is rotated by the drive wheel 8.
Demineralize the dried fish by tilting it and take out the washed salted dried fish.

<Effect of explanation> According to the present invention, desalination and cleaning are carried out using a combination of pre-treatment ultrasonic vibration that allows water to be sufficiently absorbed by the osmosis tank A, and a heterogeneous cleaning action on air bubbles. As a result, cleaning and desalting can be carried out quickly and reliably without damaging the objects to be cleaned due to stirring or jet water flow. Furthermore, if ozone is used as air bubbles, it is possible to brighten the colors of vegetables, etc. and also achieve sterilizing and disinfecting effects.
