DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for cleaning ice tubes in a machine for making ice confectionery such as ice candy.

[0002]

2. Description of the Related Art The outline of an ice confectionery machine to which the present invention is applied is as follows. In an automatic ice candy production line called a bitter line, a plurality of (12 or more) ice tubes are connected in a row to a mold. In this state, it is connected to the chains on both sides at equal intervals, sequentially moved to the raw material supply unit, freezing unit, product takeout unit, washing unit by tact movement, and supplies a predetermined amount of raw material into the ice tube at the raw material supply unit and freezes it. The raw material in the ice tube is frozen by passing through the brine tank containing the refrigerant liquid at the section, and the frozen product is automatically extracted and commercialized at the product extraction section, and the ice tube after product extraction is placed under the brine tank. Is returned to the raw material supply unit in the upside down direction, and in the middle thereof, passes through the washing unit to wash the inside of the ice tube.

In a conventional ice tube washing apparatus, an ice tube is washed by continuously jetting washing water having a constant pressure from a nozzle fixed at a fixed position. In this case, one or two nozzles were used for one ice tube.

[0004]

In the above-mentioned conventional ice tube cleaning apparatus, the cleaning water jetted from the nozzles is sprayed only to a certain portion of the ice tube, so that there are places where cleaning is possible and places where cleaning is not possible. However, there is a disadvantage that the inside of the ice tube cannot be washed evenly. Therefore, conventionally, it is necessary to perform brush cleaning manually once every one to two weeks, which is a wasteful and time-consuming work.

SUMMARY OF THE INVENTION An object of the present invention is to solve the problems of the conventional apparatus and to provide an ice tube cleaning method and apparatus in an ice confection making machine that can automatically and uniformly wash the inside of an ice tube and save labor. .

[0006]

According to the method of the present invention, a plurality of ice tubes are connected at equal intervals to both sides of a chain in a state where a plurality of ice tubes are connected to a single row of formwork. The tactile movement sequentially moves to the raw material supply section, freezing section, product take-out section, and washing section, where the raw material supply section supplies a predetermined amount of raw material into the ice tube, and the freezing section submerges the brine tank containing the refrigerant liquid. The product in the ice tube is frozen by passing through, and the product frozen in the product take-out section is automatically extracted to produce a product.The ice tube after product extraction is returned to the raw material supply section with the lower part of the brine tank turned upside down and turned upside down. In an ice confectionery machine that passes through the washing section on the way and cleans the inside of the ice tube, washing water of substantially constant pressure is constantly jetted toward the ice tube from nozzles corresponding to the plurality of ice tubes, and the tact movement is stopped. Blow high-pressure air or high-pressure heated steam into the nozzle Increase crowded by injection force of the washing water, moreover, it is to wash the nozzle laterally moved back and forth by the ice tube automatically.

[0007] Further, the apparatus of the present invention comprises a plurality of ice tubes.
Connected at equal intervals to the chains on both sides while being connected to the row formwork, move sequentially to the raw material supply section, freezing section, product takeout section and washing section by tact movement, and a predetermined amount in the ice tube at the raw material supply section In the freezing section, the raw material in the ice tube is frozen by passing through the brine tank containing the refrigerant liquid in the freezing section, and the frozen product is automatically extracted and productized in the product extracting section. The ice tube is returned to the raw material supply section with the lower part of the brine tank turned upside down, and in the middle of the ice confectionery machine that passes through the washing section and cleans the inside of the ice tube, a nozzle corresponding to a plurality of ice tubes, A pump that constantly supplies cleaning water having a constant pressure, intermittent jet injection means that increases the jetting power of cleaning water by blowing high-pressure air or high-pressure heating steam into the nozzle while the tact movement is stopped, During stop, the above Which is constituted by the lateral swing means for imparting reciprocating movement transverse to Le.

At the lower part of the cleaning section d, as shown in FIG.
A washing water collecting container 14 is provided, and the pump 7 is configured to filter the washing water m in the washing water collecting container 14 with a filter and to supply the filtered water m to the nozzle 6, and tap water or the like is appropriately supplied. . The washing water m is appropriately heated and supplied as warm water, so that the washing effect in the ice tube 1 is improved.

The nozzles 6 are branched from the common header tube 6a in accordance with the mounting pitch and the number of the ice tubes 1 to be mounted. A jet nozzle 8a is provided. The jet nozzle 8a is branched and installed on a common header tube 8b. A high-pressure air tank 8d provided with a compressor 8c is connected to the header pipe 8b by piping, and an electromagnetic on-off valve 8e is installed in the middle of the pipe. The electromagnetic on-off valve 8e is connected to the control device 8f in connection with the tact device 13. As a result, it is closed when the ice tube moves in the tact motion, and is opened when stopped. Although the embodiment of the drawing illustrates the case where high-pressure air n is used, this may use high-pressure heated steam. In that case, an appropriate heating steam generator is used.

The injection pressure of the high-pressure air n is set so that the washing water m can be blown up to a height higher than the height of the bottom surface of the ice tube 1, and the water pressure by the pump 7 is set to a lower pressure. You.
