Description

  The present invention relates to a fryer for cooking foods mainly for business use in deep-fried foods such as tempura and fries, and in particular, to a fryer equipped with a function of always discharging the frying rice cake generated during cooking out of the oil tank. .

  Fried food cooking is a cooking method in which food is heated using a large amount of high-temperature oil as a heat medium. A cooking method in which heat is uniformly applied from the surroundings of the ingredients even though the heating time is short, and the oil surface, texture and fried color are given to the surface of the food, while cooking oil is heated and oxygenated from the time it is heated The deterioration of cooking oil begins due to the influence of ingredients and the like. Therefore, for fried food cooking, it is important to employ appropriate devices and tools and to properly manage fried food cooking.

  In order to suppress the deterioration of cooking oil, control of heating temperature and heating time, separation operation of cooking oil and fried rice cake during cooking, removal operation of fried rice cake from cooking oil, contact of cooking oil with air, etc. However, the inventor of the present application paid attention to the operation for removing the deep-fried rice cake from the cooking oil.

  Deep-fried rice cakes are produced when the ingredients are peeled off while cooking fried food. If the fried rice cake is left in the cooking oil, the fried rice cake is carbonized, and the carbonized fried rice cake promotes deterioration of the cooking oil. Moreover, if the fried rice cake stays in the cooking oil, the fried rice cake may adhere to the fried food and lead to a reduction in cooking quality. Therefore, in deep-fried food cooking, the removal operation from the cooking oil of the deep-fried rice cake which arises during cooking is essential.

  As a deep-fried food cooking apparatus, the fryer which cooks a deep-fried food in a commercial kitchen is known conventionally, and various proposals about the fryer and the removal device of the deep-fried food provided in a fryer are made (for example, patent documents 1-2). reference).

Each of the oil tanks is connected to the bottom 17 on the upstream side. Therefore, the suction of cooking oil from the oil tank pump 107 causes a cooking oil flow in the longitudinal direction in the oil tank 13 to occur over the entire width of the oil tank 13, and the upstream ends of the front part 14 and the rear part 15 of the oil tank 13. The cooking oil flows from the oil tank 13 toward the downstream end of the filtration arrangement portion 21 inside the oil tank 13. In addition, the feed amount of cooking oil is not particularly limited as long as the food material 122 transported by the transport conveyor 31 does not flow backward, and in this embodiment, cooking is performed at a flow rate of 200 L / min with respect to a 200 L oil tank. Oil is circulated, and is set to such an extent that cooking oil circulates in the oil tank 13 and the circulation part 101 once a minute, and is adjusted by a valve 112 provided in the discharge pipe 106.

  The operation during cooking of the fryer 1 according to the present invention is as follows. When the food material 122 is introduced from the input portion 33 provided in the oil tank 13 filled with cooking oil, the food material 122 is placed on the upper surface of the conveyor 31. The food material 122 is conveyed to the take-out section 34 while being sandwiched between the upper surface of the conveyor 31 and the lower surface of the presser conveyor 32. Further, during cooking of the deep-fried food, the cooking oil filled in the oil tank 13 is caused by the suction of the transport pump 107 so that the cooking oil flows in the longitudinal direction in the oil tank 13 over the entire width of the oil tank 13. 13 and the circulation unit 101 are circulated. Due to the circulation of the cooking oil, the deep-fried rice cake generated during cooking flows from the upstream side to the downstream side of the oil tank 13 by the flow of the cooking oil, and the cooking oil containing the deep-fried rice cake passes through the filter 43, and the cooking oil The fried rice cake is separated. The cooking oil filtered by the filter 43 is discharged to the oil tank 13 through the circulation part 101, and the separated fried rice cake is carried out from the oil tank 13 by the fried rice cake conveying part 91 and the fried rice cake discharging part 97. . Therefore, the cooking oil flows from the upstream side to the downstream side of the oil tank 13 and the food material 122 is conveyed from the rear part 15 to the front part 14 of the oil tank. Therefore, the cooking oil flow and the conveying direction of the food material 122 are different. . Furthermore, when the cooking oil is circulated, the cooking oil is sucked using the transport pump 107, so that the fried rice cake is attached to the filter 43, but the scraper unit 61 and the cleaning discharge unit 81 are attached to the filter 43. Scrape fried rice cake to remove clogging.
