Description

TECHNICAL FIELD The present invention relates to an oil disposal system that separates and collects oil adhering to a cooker hood, thereby simplifying oil disposal and eliminating the need for cleaning.

Part of the oil becomes oil mist due to the use of the microwave for cooking with oil content, and the oil mist according to the use mainly adheres to the filter, but also adheres to the entire hood as a film from the suction of the ventilation. The layer, which is liquid at the time of adhesion but has adhered in the form of a film, becomes an oil layer due to the presence of oils and fats that solidify at room temperature, and accumulates to grow thicker.

If the amount of ventilation is small in such facilities, there are many small facilities that directly pass through the hood and exhaust to the outside air. However, if the accumulated oil content exceeds the allowable range, it will drip, so it is necessary to perform maintenance such as cleaning in a timely manner. In addition, if the equipment is medium or higher, the amount of ventilation will be large, the opening of the exhaust will be large, and the heat exchange loss when not in use will also increase. ing. In addition, this shutter equipment also accumulates a thick layer of oil in the shutter over time, and due to the adhesive action of the oil locally, it becomes intermittent adhesion or sticking when opening and closing, resulting in unstable operation or blocking. Further cleaning and maintenance is necessary because it also causes defects such as non-operation.

It is a facility that is used frequently on a daily basis, and these defects are a big obstacle, so it is required to remove oil and clean it so that problems do not occur. In order to do so, it is necessary to perform cleaning maintenance such as cleaning and scraping with detergent, or melting with high-temperature water.

As a measure to solve this problem, the entire hood equipment is heated up by an electric heating method when the generated oil mist adheres to the hood equipment when the oil is used for cooking with heat. When the oil adheres, it is in a liquid state, and this device separates and fluidizes the oil. In this situation, it is possible to maintain the fluidized state of the adhering oil by temperature control, and also to centrally collect and manage this by providing a gradient throughout the hood facility. As a result, the present invention relates to an oil treatment system in which maintenance can be done simply by discarding oil and cleaning is not required.

The problem to be solved is to separate and fluidize the entire hood equipment by heating up the entire hood equipment by the electric heating method while keeping the oil in a liquid state so as not to solidify the oil adhering to the entire hood equipment. In addition, it is necessary to provide a gradient throughout the facility so that it does not settle in that part, and to fluidize it so that it can be collected and managed.

The main feature of the present invention is that it is a system in which an electric heating system device is installed in the entire food facility, and heating is performed by selecting the use of cooking by heating with oil. In addition, the entire hood facility is provided with a gradient for receiving oil so that oil can be collected at one point as much as possible and management can be performed.

The advantage of the present invention is that the collected oil can be disposed of simply by discarding it, so cleaning and maintenance of the equipment is essential, but the oil processing system does not require this cleaning. is.

Two types of heaters are used in the electric heating method to heat up the entire hood. One is a belt-shaped heater of the direct heat conduction heating system for the entire hood, which is made into the same unit type as the oil fluidization receiving frame so that it can be easily processed, installed and sloped. The heater heat generation amount per unit area and the function of each system are also taken into consideration in the design, so that each system can be controlled by the same temperature control.
The other is to use a sheathed heater as a gas heating method, which does not cause problems even if oil adheres to the parts of the fan or shutter where there are many gaps. Also, in this usage, the loss of energy is large when used during ventilation, so after the fan stops, the shutter is shut off and then it works for a certain period of time.
An electronic temperature control device is used to fluidize the oil while maintaining the heat up of the entire hood from room temperature to the maximum temperature of 50 degrees Celsius. In addition, the entire hood facility is provided with a slope so that the oil can be collected at one point as much as possible, so that collection management can be performed.

The present invention has a higher utility in industry. It is that the operation of cooking with oil content in the microwave takes a long time. The oil mist of oil accumulates on the entire hood for a long time, and the amount of adhesion increases, so frequent cleaning and maintenance is required. Troublesome time, work, expenses, etc. required for maintenance related to this will arise. If this cleaning and maintenance can be done by simply discarding the oil, and if an oil treatment system that does not require cleaning is created, industrial trouble will be eliminated and there will be a great advantage in terms of maintenance and management.

Claims (5)

This equipment heats up the entire food equipment from room temperature to a maximum temperature of about 50 degrees Celsius in order to separate and fluidize the oil that adheres to the entire food equipment.
For this, a belt-shaped heater is used as a direct heat conduction heating method with an electric heating method heater because of the good heat conduction due to surface contact and the simplicity of processing and temperature control. The same unit type as the oil fluidization receiving frame is processed, and the heater calorific value per area and function of each system are taken into consideration, and each system can be controlled by the same temperature control and timer. From the same conditions as above, there is no problem even if oil adheres to the gas heating method for heating the part with many gaps such as the fan or the shutter, and it can be adapted to the shape and the temperature control is simple. Also use a sheathed heater. The installation position should be somewhere between the two, and the maximum surface temperature of the object to be used should be about 50 degrees Celsius, which can be controlled by temperature control and a timer. As for how to use the heater to heat the part with many voids, the energy loss is large and the efficiency is low during use during ventilation. Therefore, the stop fan shutter is also shut off to stop air movement before heating the adherent surface. The dropped oil should be heated for a certain period of time and controlled by a timer so that the dropped oil is retained at the case position where it can be reflowed when the case is heated up next time. The belt-shaped heater that heats up the entire hood equipment and the channel steel type (middle 2 division) metal or heat-resistant resin material oil fluidization receiving frame are made into the same unit type so that processing, installation and slope can be done easily. do. Also, taking into account the amount of heat generated by the heater per unit area and the function of each system, each system can be controlled by the same temperature control and timer. The oil fluidization receiving frame is provided with a slight slope throughout the hood, and collection and management can be performed by concentrating and collecting oil from the entire hood facility as much as possible at one point. Therefore, the oil processing system is characterized by the fact that the oil can be simply discarded and no cleaning is required.
