Description

Food tray cleaning system {Washing system for tray}

The present invention relates to a food plate cleaning system, and relates to a food plate cleaning system for infants that can stably remove food residues present in the container grooves formed on the food plates by sequentially inserting and cleaning more regularly formed food plates in an inverted position. will be.

In general, dishwashers automatically wash and dry large quantities of dishes, and these dishwashers are mainly installed in large restaurants that serve group meals, such as hotels, hospitals, schools, kindergartens, factories, and military.

In this way, a dishwasher that automatically cleans a large amount of dishes is equipped with a conveyor to transport plates and dishes, a bubble water tank to bubble the plates and dishes, and spraying washing water and rinsing water on the bubbled plates and dishes. A washing room and a rinsing room are installed, and a drying room is also installed to dry washed plates and dishes.

However, in the past, there was an inconvenient problem that workers had to manually separate the food plates and bowls one by one and put them into the washing room. Additionally, because the food plates and bowls were separated and washed separately, a lot of manpower and work time were structurally required, resulting in labor costs. There were a number of problems, such as a large increase in and a long cleaning time being required.

In addition, by allowing the food plates and dishes to bubble in the bubble water tank before washing them, it takes more time for them to bubble in the bubble water tank, reducing the inconvenience and cleaning and drying time in the process of washing and drying the food plates and dishes. There was an inconvenient problem of not being able to do it.

In addition, conventionally, when washing food plates, the food plates were tilted and moved while washing them using washing water containing detergent.

When cleaning the food trays by standing them up like this, there is a problem in that the food residue remaining in the container grooves formed on the trays is not completely removed and sticks there during the drying process, resulting in incomplete cleaning and thus creating dirt.

In addition, there is a problem of causing cleaning defects during the main cleaning process because it is practically difficult to thoroughly inspect each plate for the presence of foreign substances before being put into the main cleaning process.

Foreign matter caught in the brush roller may be shaken downward due to the vibration generated. That is, the brush rollers may be capable of self-cleaning.

In addition, a tilt angle variable device capable of variably adjusting the tilt of the transport chain is further installed in the movement path disposed in the dewatering and drying unit according to the present invention. The inclination angle variable device forms a rotation axis at one end of the section of the dewatering and drying section, and can adjust the inclination by raising and lowering a drive shaft connected to the other end of the transfer chain using a cylinder that is raised and lowered.

In this case, the hot air blower disposed at the top of the transfer chain in the dehydration and drying section is equipped with a hot air sprayer that rotates up and down by being driven on a rotator, so that the direction in which hot air is sprayed can be adjusted.

Accordingly, when the transfer chain in the dehydration and drying section is inclined upward at a certain angle from one end to the other end, the hot air blower at the top of the inclined section makes the direction in which the hot air is sprayed opposite to the direction of movement of the food plate, and follows the inclined movement path. You can also achieve an oblique spray direction to completely shake off any remaining water on the plate.

Meanwhile, an image capture device may be further installed in each of the first and second cleaning units to obtain images of the lower portions of the first and second cleaning plates that are moved. The image acquirer transmits the first and second images acquired during the first and second cleaning, respectively, to the control unit.

Here, since each of the food plates moves along the movement path in an inverted state, the acquired first and second images include images of the container grooves of the food plates.

The control unit is set to a reference image that can determine whether foreign matter exists in the container groove.

Based on this, if foreign substances are found during the first cleaning process in the first cleaning unit, the control unit can control the operation of the brush roller rotating unit and the driving motor so that the rotational speed of the brush rollers and the moving speed of the moving chain are below a certain level. there is. Accordingly, the time during which the first cleaning of the corresponding food plate is performed can be extended beyond a certain level, thereby increasing the cleaning efficiency.

Additionally, if a foreign substance is found during the second cleaning process in the second cleaning unit, the control unit may increase the hot water spraying pressure of the hot water spraying unit above a certain level and control the moving speed of the moving chain to be below a certain level. Accordingly, the cleaning efficiency can be increased by increasing the time during which the second cleaning of the corresponding food plate is performed and the spraying pressure of the cleaning solution.

The above-described present invention may be subject to various substitutions, modifications, and changes without departing from the technical spirit of the present invention to those skilled in the art to which the present invention pertains. It is not limited by .
