2. Description of the Related Art When manufacturing fried foods such as fried chicken, croquettes, pork cutlet, and tempura in a food manufacturer, a food service company, a restaurant, etc., a cooking utensil for business use called a fryer is used. In the fryer, a heating device such as an electric heating device and a gas stove is integrated with a deep pot-shaped processing tank. The oil and fat filled in the processing tank is heated by a heating device to be convected.

When fried foods are produced with this fryer, a cooking method generally called a deep fried method is used. The deep frying method heats the temperature of the oil / fat filled in the treatment tank to 130 ° C to 220 ° C, puts the food in the heated oil / fat and immerses it, and transfers heat to the food by convective oil / fat to heat it. It is a cooking method to do.

According to the above-mentioned conventional fryer, the deep pan-shaped processing tank is formed in such a size that a large amount of food can be immersed in a batch at a time, and a large amount of oil and fat is sufficiently convected into the processing tank. Is filled with oil and fat. Therefore, a large amount of fats and oils is required at one time, and since the same fats and oils are reused without being replaced, impurities such as oil cake are mixed in the fats and oils at the stage where cooking is finished several times, and this adheres to food, Since it promotes the contamination of fats and oils, all the fats and oils are exchanged and discarded in a short cycle after several cooking steps.

Therefore, the amount of fats and oils to be discarded is very large, the cost is high, and there is a demand for improvement in view of environmental problems.

Therefore, as an improvement of the above problem,
Multiple stages of shallow pan-shaped cooking trays that store food without stacking are stacked, the stacked products are stored in the processing tank, and the oil and fat heated by the injection nozzle installed in the processing tank is heated. A method of spraying onto a cooking tray and directly applying oil and fat to the food in the cooking tray to cook fried foods [Japanese Patent Application No. 3-261285], or a shallow pan shape containing foods as above The heating and cooking trays are stacked in a plurality of layers and housed in the processing tank, and the heated oil and fat is directly flowed down to the food in the heating and cooking tray from the oil outlet provided in the processing tank. , A method of cooking fried foods [Japanese Patent Application No. 3-261286] has been proposed.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention
In each case, the fats and oils are collected each time they are cooked, and impurities such as oil cake are removed from the fats and oils for reuse. Therefore, the purity of the oil / fat is kept high, and the oil / fat can be used for a long period of time. Moreover, the cooking tray has a shallow pan shape, the amount of the oil / fat used is small, and the amount of waste can be reduced.

However, the above-described heating and cooking device causes oil and fat to flow to the uppermost part of the heating and cooking trays that are stacked in a plurality of stages, and is lowered from the discharge hole formed at the bottom of each of the heating and cooking trays. By overflowing from the upper end of the tray, the oils and fats are sequentially dropped from the upper cooking tray to the lower cooking tray, and the food contained in each cooking tray is cooked.

Therefore, the cooking conditions are different due to the temperature difference of the oils and fats in each heating and cooking tray, and the quality is varied. In addition, even if the supply of oil and fat is stopped at the end of cooking, the oil and fat are sequentially discharged from the upper cooking tray,
There was a time lag between the oil discharges, and the oil depletion of the food itself also varied, resulting in variations in the quality of the food.

Even if a jet nozzle or the like is arranged between the heating and cooking trays so that the fat and oil flow at the same time, the fat and oil still flow from the upper stage to the lower stage, which causes variations in cooking. Moreover, in this structure, since the ejection nozzles and the like are provided between the heating and cooking trays, the heating and cooking device becomes very large, and the oil supply device and the like also become large.

The present invention relates to an oil supply nozzle for simultaneously and uniformly supplying oil and fat to each of the stacked heating and cooking trays and discharging the oil and oil evenly.

[0012]
