Description

  The present invention relates to a technique for cleaning a cylindrical body such as the inside of a screw conveyor or the inside of a pipe.

  In factories such as hanpen, kamaboko, chikuwa, ham, sausage, and other foods and beverages such as marine products and dairy products, screw conveyors or transport pipes are provided. In this type of factory, it is necessary to clean these parts. When cleaning the screw conveyor, the parts are usually disassembled and cleaned.

  However, the above-described cleaning method is troublesome, takes time, and is expensive. In particular, it takes time to mean that the equipment is stopped during that time, and the productivity is reduced accordingly.

  Therefore, the problem to be solved by the present invention is to provide a technique which can be cleaned quickly, easily and cleanly.

  By the way, the inventor of the present application noticed that when the screw conveyor was being washed, there was snow in the surroundings. I noticed that the screw was beautiful enough to become shiny.

  Therefore, as a result of careful investigation on this reason, it has been found that the dirt attached to the screw is scraped off by the snow fed by the screw conveyor. In addition, it has been found that this dirt is scraped not only to the screw but also to the inner wall of the screw conveyor.

The present invention has been made based on such knowledge.
That is, the problem is a cleaning method for cleaning the cylinder,
The problem is solved by a cleaning method characterized in that a cooled or solidified particulate or powdered substance of a substance in a liquid state at normal temperature is supplied into the cylinder and is transferred under pressure.

And a cleaning agent,
The cleaning agent is
A substance in a liquid state at room temperature is cooled and solidified,
This is solved by a cleaning agent characterized in that it is a granular or powder of the cooled and solidified material.

  In the present invention, the substance that is in a liquid state at room temperature specifically includes water that is the above-mentioned snow source. However, with water alone, the purpose of cleaning can be achieved, but the effect of disinfection and sterilization cannot be achieved. In food factories and the like, it is preferable to carry out cleaning, disinfection and sterilization. Therefore, the substance that is in a liquid state at room temperature is preferably a liquid having a bactericidal effect. Specific examples include bamboo vinegar. Moreover, a wood vinegar liquid is also mentioned. Moreover, ethanol aqueous solution etc. are also considered.

  In addition, there is no special restriction | limiting in the magnitude | size of the powdery material used by this invention, or a granular material. However, if it is too large, it is difficult to put it into the screw conveyor or pipe. That is, it is difficult to use. And since washing | cleaning is performed so that dirt may be scraped off with a powdery thing or a granular material, a contact area will reduce and the washing | cleaning effect will also fall. Accordingly, the average diameter is preferably 5 cm or less, more preferably 3 cm or less, and even more preferably 2 cm or less. The lower limit value is sufficient if it has a size having polishing ability. However, in the present invention, a liquid material is frozen at a normal temperature with a refrigeration apparatus and is crushed. Therefore, since the cleaning agent of the present invention melts into a liquid unlike normal ones at room temperature, if it is too small, it immediately melts into a liquid state. And in the liquid state, the cleaning effect by the rubbing action cannot be expected. That is, the object of the present invention is hardly achieved. Accordingly, those having an average diameter of 0.5 cm or more are preferable.

  At room temperature (normal temperature in the environment in which it is used. For example, if it is indoors, the temperature inside the room) By supplying and applying pressure, and transporting inside the cylinder, dirt inside the cylinder, for example, in the case of a screw conveyor, the dirt adhering to the screw or the inner wall is scraped off cleanly.

After the completion of this operation, the granular material or powdery material used for cleaning melts and becomes a liquid, so that the subsequent cleaning is really easy. For example, it is completed only by pouring it into the sewage with dirt.
Therefore, the cleaning operation is performed very quickly and easily.

  In some cases, further sterilization (disinfection) is performed at a time. As a result, in food factories and the like, cleaning and sterilization (disinfection) are performed in a short time, and the downtime of the equipment can be shortened, and the economic effect is very great.

BEST MODE FOR CARRYING OUT THE INVENTION

  The cleaning method according to the present invention is a cleaning method for cleaning the inside of a cylinder, and cooling / cooling substances that are in a liquid state at room temperature (for example, water, other aqueous solutions, bamboo vinegar solution, wood vinegar solution, ethanol aqueous solution, etc.). This is a cleaning method in which a solid or powdery solidified product is supplied into the cylinder, and pressure is applied to move the cylinder. And since the granular material or powdery material of the cooling / solidified material used for cleaning melts into a liquid material, it is sent to a treatment facility such as sewage together with the cleaned and removed dirt.

  The cleaning agent according to the present invention is obtained by cooling and solidifying a substance (for example, water, other aqueous solution, bamboo vinegar solution, wood vinegar solution, ethanol aqueous solution, etc.) that is in a liquid state at room temperature. It is a granular or powdered product. The size of the granular material or powdery material is about 0.5 to 5 cm (3 cm or less, and further 2 cm or less) in average diameter.

This will be specifically described below.
FIG. 1 is an explanatory diagram of a cleaning method (cleaning in a screw conveyor) according to the first embodiment of the present invention.

  1 is a screw conveyor installed in a food factory, for example. Reference numeral 2 denotes a hopper which is an input port through which an object is put into the screw conveyor 1, 3 denotes a motor which is a driving source of the screw conveyor, 4 denotes a belt which transmits driving force of the motor, and 5 denotes a screw. In addition, since the structure of such a screw conveyor 1 is known, detailed description is abbreviate | omitted. And the used food material has adhered strongly to the screw 5 inside the screw conveyor 1, or the inner wall of the screw conveyor 1. FIG.

  By the way, the bamboo vinegar liquid powder and granules that have been frozen by the ice making machine 6 and finely crushed (average size is about 1 cm) are put into the hopper 2 and the bamboo vinegar liquid The screw conveyor 1 was made dense with powdery or granular materials and rotated. That is, a powdered product or a granular product obtained by cooling, solidifying, and crushing the bamboo vinegar was pumped in the screw conveyor 1.

  Then, due to this pumping, the dirt that was firmly attached to the inner wall of the screw conveyor 1 and the screw 5 was scraped off, and it became shiny. That is, since it was subjected to the action of being polished by powdered or granular materials, it was removed quite neatly.

  Moreover, since the above removal (cleaning) was performed using bamboo vinegar, it was also disinfected and sterilized, and the cleaning and sterilization (disinfection) was performed at once. Become.

  FIG. 2 is an explanatory diagram of a cleaning method (cleaning in a bent transport pipe) according to the second embodiment of the present invention.

  In this embodiment, the transport pipe 11 is bent as shown. For this reason, dirt is easily attached to the curved portion 12 and the dirt is firmly attached.

  Therefore, as in the case of the above-described embodiment, the bamboo vinegar liquid powder or granule which has been frozen by an ice making machine and finely crushed (average diameter is about 1 cm) is extracted with a plunger pump. Etc., the inside of the transport pipe 11 was pumped.

  As a result, due to the above-mentioned pressure feeding, the dirt adhered firmly to the inner wall of the transport pipe 11, particularly the inner wall of the bent portion, was scraped off and became shiny. That is, since it was subjected to the action of being polished by powdered or granular materials, it was removed quite neatly.

  Moreover, since the above removal (cleaning) was performed using bamboo vinegar, it was also disinfected and sterilized, and the cleaning and sterilization (disinfection) was performed at once. Become.
