In the ware-making apparatus provided with the wire-mesh cleaning device of the wire-mesh chain conveyor according to the present invention, food for wares such as meat and seafood is formed of an endless wire-mesh of the wire-mesh chain conveyor, especially made of stainless steel. It is placed on an endless wire mesh and baked. In this case, the food for ware is held in an endless wire mesh so that the contact area becomes smaller, and is heated in the far infrared heating furnace by radiant heating by irradiation of far infrared rays from above and below and direct heating by the ambient temperature. It In the case of teriyaki, the ware baked from the far-infrared heating furnace is coated with sauce, and then sent to the teriyaki section for baking. In this case, the endlessly formed wire-meshing wire net is cleaned and circulated for use, for example, through a far-infrared heating furnace, a sauce coating part, a burning part, a pottery extract part, and a wire-mesh part cleaning tank. It It is preferable that the wire net cleaning tank is formed below the sagging coating section, the firing section and the extraction section in order to increase the space factor of the ware-making apparatus.

In the present invention, the endless wire netting of the wire netted chain conveyor, which is burnt, that is, the wire netting portion, uses a cleaning liquid to dissolve and remove the oil and fat adhering to the wire netting portion together with the charring. In the present invention, the cleaning liquid is produced from a solvent that dissolves fats and oils such as fats and oils and is water-soluble and hardly volatilizes. For example, 0.5% of a caustic alkali such as caustic soda and caustic potash or a mixture thereof is used. % To 4.0% strength aqueous solutions can be used. In the present invention,
It is preferable that the washing is performed under heating so that the washing with the detergent is completed in a short time. In this case, the temperature of the cleaning liquid in the wire net cleaning tank is set to 60 ° C. or higher, but the cleaning effect increases as the temperature of the cleaning liquid increases, so it is preferable to set the temperature to 80 ° C. or higher.

[0008] Under such a heated temperature, a considerable amount of steam is generated from the cleaning liquid. Therefore, in order to prevent these steam from flowing into the sagging coating part, the burning part and the extraction part, the wire mesh cleaning tank Provides a water sealing tank on the inlet side and the outlet side thereof to form a water sealing portion therein. In the present invention, the water sealing portion is located above the wire mesh cleaning tank, and a shielding wall that is airtightly connected to the side wall of the cleaning tank is provided on the water sealing tank provided on the inlet side and the outlet side of the cleaning tank.

In the present invention, since the water-sealing tanks are formed on the wire mesh portion of the wire mesh chain conveyor, that is, on the inlet side and the outlet side of the wire mesh portion cleaning tank, the wire mesh portion of the wire mesh chain conveyor with charring has a temperature similar to that of the cleaning liquid. Therefore, the wire mesh cleaning tank can be made to meander without lowering the contact temperature with the cleaning liquid.

In the present invention, the wire mesh portion of the wire mesh chain conveyor that has been washed with an aqueous solution of caustic alkali has a weakened adhesive force to the wire mesh portion because the oil and fat are dissolved and removed. The attached charcoal is easily removed from the wire mesh portion by ultrasonic waves or brushing. Therefore, in the present invention, an ultrasonic oscillating device is provided on the outlet side of the wire net cleaning tank so that ultrasonic waves can be applied to the wire net surface of the wire net.

The outlet side water sealing tank of the endless wire net cleaning tank cleans the caustic aqueous solution adhering to the endless wire net as much as possible, and overflows water at a temperature of, for example, about 45 ° C. so that the ultrasonic water cleaning can be effectively performed. Circulation is preferred.

[0010]

According to the present invention, since the wire mesh portion of the wire mesh chain conveyor having the scorched charcoal to be cleaned is immersed in an aqueous solution of caustic alkali, especially a water solution of heated caustic alkali during movement, it adheres to the wire mesh portion together with the charcoal. The oils and fats that dissolve are dissolved in a caustic aqueous solution and easily removed. Particularly in the case of a heated caustic aqueous solution, the higher the heating temperature, the shorter the immersion time in the caustic aqueous solution for scorching cleaning, and the wire mesh part can be cleaned in a relatively short time. . Moreover, since the wire mesh portion is washed by a treatment operation that is easy to automate, such as immersing in a caustic aqueous solution while the wire mesh portion is moving, the automation is simple and easy.

In the present invention, after the wire mesh portion of the wire mesh chain conveyor is immersed in the caustic aqueous solution, the wire mesh portion wet with the alkaline aqueous solution is heated to a temperature similar to or higher than the temperature of the caustic aqueous solution. Since it is contacted with the water vapor that it has, and then this wire mesh part is immersed again in the heated caustic alkali aqueous solution, the wire mesh part continues to come in contact with the caustic alkaline aqueous solution at the heating temperature and adheres to the wire mesh part. The oils and fats are exposed to a state in which they are easily dissolved in a caustic aqueous solution, and the oils and fats attached to the wire mesh portion are removed. As a result of the oil and fat adhering to the wire netting portion being removed in this way, the charring adhered to the wire netting due to the oil and fat becomes like the peeling off from the wire netting portion and can be easily removed. Moreover, in the present invention, since the ultrasonic cleaning is performed in the water washing step, scorching is easily removed from the wire mesh portion, and the adhesion of caustic alkali to the wire mesh portion is reduced. It can be simplified.
