Description

  The present invention relates to a fryer that collects fried waste for the purpose of rationalizing cooking operations and preventing deterioration of oil.

  In a fryer that is a deep-fried cooker, there is a two-layer fryer (Patent Document 1) that floats oil on water to prevent deterioration of the oil and has a water layer and an oil layer. This fryer does not automatically collect deep-fried dregs by simply floating the oil on the water. A few flyers of this construction are seeing constant spread. In contrast, the two-layer structure of water and oil is the same, but in order to save the labor of cleaning the oil tank every day, a filtered water tank is provided outside the oil tank, and the water at the bottom of the oil tank is circulated between the filtered water tank and fried. There was a water circulation type fryer (Patent Document 2) having a mechanism for automatically separating scum and discharging it to the outside of the oil tank.

  In the two-layer fryer of water and oil, the fried residue accumulates in the water layer at the bottom of the storage tank and decays over time. In order to avoid this, it is necessary to drain and clean the oil and water in the storage tank every day, and there are directions that are avoided as troublesome work. On the other hand, as a means for solving the above problems, a water circulation type fryer was devised that has a water tank that forcibly circulates water with a pump and collects the frying waste outside the storage tank, but the mechanism is complicated and expensive. There is also concern about the problem of failure frequency due to complexity. The present invention has been made to solve the above-described problems in the prior art. The specific problem to be solved is that, in a two-layer fryer with water and oil, the frying waste that has fallen from the oil layer as the cooking layer to the water layer at the bottom is efficiently discharged to the outside, and the frequency of failure is low The object is to provide an inexpensive flyer with a simple structure and mechanism.

  The problem solving means specifically configured to cover all matters recognized as necessary for solving the above-described problems will be described below. The first solution for realizing an inexpensive fryer with a simple structure and mechanism with low failure frequency, which efficiently and manually discharges the fried residue to the outside, is the mechanism that realizes this purpose. It is to be constituted only by the water flow by the structure and the water pressure such as tap water. It does not have a tank for collecting fried waste outside the storage tank, and therefore it does not have a piping structure that circulates between the storage tank and the outside of the storage tank. It is possible to provide an inexpensive water-oil two-layer flyer with a simple structure and mechanism with minimal elements.

  The component of the first means of the concrete solution is to make the structure of the lower part of the storage tank a shape close to a substantially inverted conical shape, and to form a cylindrical reservoir tank in the lower part of the storage tank. The fried debris that sinks from the boundary surface between the water layer and the oil layer is deposited and deposited on the upper surface of the inverted conical shape, but the surface of the inverted conical shape is smooth, and the fried debris is easy to slide down. It is structured to enter the tank. However, although the fried residue has a smooth structure that is easy to flow into the residue reservoir, not all of the raised residue deposited on the inverted conical surface flows into the residue reservoir. As a result, the fried dregs are deposited and deposited on the inverted conical surfaces of the dregs storage tank and the lower part of the storage tank in a state where injection and discharge of clean water and the like are not performed. Moreover, when injection of clean water or the like is performed and a water stream is generated, the fried residue is efficiently guided to the residue storage tank by the water stream.

  The second component of the specific solution is to install single or multiple nozzles on the outer periphery near the bottom of the water layer of the storage tank in order to efficiently guide the fried residue to the discharge part, It is to inject water using the water pressure. The fried debris deposited on the inverted conical surface by the water flow generated by the injection is swept away and guided to the settling tank of the debris storage tank at the lower part of the storage tank, so that the fried debris does not settle and accumulate on the reverse conical surface. By discharging the fried dregs in the dregs pool, the factor of fried dregs decay can be reduced and the quality of the fried oil can be kept good. The shape of the nozzle or nozzles installed on the outer peripheral portion close to the bottom surface of the water layer forms a water flow spreading in a fan shape on the plane. The ejection direction seen from the upper surface of the water flow coming out of the nozzle is set to be offset from the inverted conical center, and the water flow flowing through the reverse conical storage tank water layer fluidizes the entire water layer. Moreover, the direction of the nozzle which looked at the storage tank from the side is arrange | positioned along a bottom face. Although this structure generates an appropriate wave at the boundary surface between the oil layer and the water layer, it can obtain a water flow that does not generate a large wave. When a large wave is generated at the boundary surface between the oil layer and the water layer, moisture is mixed into the oil layer, causing a risk of oil deterioration and generation of steam heated by the oil. For this reason, the direction of the nozzle is preferably slightly downward. The appropriate wave is to cause an effect of efficiently taking in the fried debris that has settled at the boundary between the oil layer and the water layer, although moisture does not enter the oil layer or generate thermal steam. The shape of the sludge storage tank has a cylindrical shape at the bottom of the inverted conical storage tank. This shape does not affect the water flow generated in the reverse conical water layer to the sludge storage tank. Prevents soaring from the tank. In addition, by setting the bottom of the dregs tank on an inverted cone, the fried dregs can be efficiently guided to the discharge valve during drainage. Moreover, since the temperature of the water by water injection is lower than the temperature of the water layer warmed by cooking, it has the effect of suppressing the temperature rise. The water injection pressure has a water pressure of about 2 atm at home and about 2 to 4 atm in a building and does not require a mechanism such as a pump.

  A rotating blade with fins that can be rotated is placed at the center of the inverted cone at the bottom of the reservoir, receives the water flow by water injection with the fins, rotates the rotating blade as a rotational force, and rubs the oil debris deposited on the bottom of the inverted cone The method in which the rotor blades are actively fried and dropping the waste into the waste reservoir is more aggressive and effective.

  When fried scum accumulates above the specified level in the puddle or when the specified cooking time has elapsed, it is necessary to drain the fried dregs and remove the dirt in the water in the storage tank. Sometimes, in a two-layer fryer having an oil layer and a water layer, when water or the like is injected from the nozzle, the water level and the oil level rise, and cooking cannot be continued as it is. On the other hand, an appropriate amount of water is discharged together with the dregs by opening and closing the discharge valve as appropriate, or by automatically adjusting the opening and closing of the solenoid valve according to the timer or sensor information. By taking it, it becomes possible to continue cooking. Specifically, a position sensor is disposed in the vicinity of the boundary surface between the oil layer and the water layer, and a sensor for the amount of frying waste is provided in the residue tank.

    In a two-layer fryer having a water layer and an oil layer, the fried residue falls into the water layer and accumulates on the bottom surface of the inverted cone below the storage tank. Accumulated fried debris can be precipitated by water ejected from the nozzle by water pressure, such as tap water, into the dregs storage tank at the bottom of the storage tank. It becomes possible to discharge from the mouth (drain) to the outside. In addition, when draining water and fried waste from the drain, it is possible to minimize changes in the amount of water and oil level in the storage tank by injecting equivalent amounts of clean water, etc. It can be carried out. As a result, there is no need to clean the water at the bottom of the storage tank, which is a weak point of the two-layer fryer with a simple water layer and oil layer, and it is possible to provide an inexpensive fryer with a simple structure and mechanism with less failure frequency. It becomes possible to do. Moreover, it is possible to prevent the fried residue from being spoiled and to suppress the deterioration of the reason for adjustment. As a result, cooking oil can be saved, there is little oil splash, there is no need to scoop fried waste during cooking, and it is possible to provide an ideal fryer that does not require daily cleaning at a low price, Arouses great demand.

  In the flyer with a two-layer structure consisting of a water layer and an oil layer, by creating a large-capacity stag reservoir tank such as a cylindrical shape, the fried scum is the bottom of the tank on the inverted cone when water is not injected or discharged It accumulates on the surface of the water or settles in the residue tank. Further, when water flow is generated by injecting clean water or the like, it is difficult to deposit on the surface of the bottom of the inverted conical storage tank due to the water flow, and it is led to a dreg pool tank where the water flow is weak and precipitates. As a result, most of the fried residue is settled in the residue and can be discharged to the outside of the fryer. This is an element that realizes an inexpensive flyer having a simple structure and mechanism that efficiently discharges fried waste and the like to the outside at a low cost and has a low failure frequency.

  In a flyer with a two-layer structure consisting of a water layer and an oil layer, in order to efficiently guide the fried residue to the discharge part, single or multiple nozzles are installed on the outer periphery near the bottom of the water layer, and water pressure such as tap water is applied when necessary. Water is injected by using it, and the fried residue etc. is pushed away by the water flow generated by the injection and collected in the residue storage tank at the bottom of the oil tank. This prevents sedimentation and adhesion to the bottom of the storage tank and reduces the cause of corruption. Can be made. By the above water injection method, the forced circulation device by the pump is eliminated, and the water circulation tank and the filter are unnecessary. Therefore, an inexpensive flyer having a simple structure and mechanism with a low failure frequency for efficiently discharging fried waste etc. to the outside can be realized.

  In a two-layer flyer consisting of an oil layer and an aqueous layer, when water or the like is injected from the nozzle, the water level and the oil level rise, and cooking cannot be continued as it is. ) Is manually opened up to a preset discharge amount, a proper amount of water is discharged together with the waste, and cooking can be continued by balancing injection and discharge. This is an element that realizes an inexpensive flyer having a simple structure and mechanism that is low in cost and has a low frequency of failure to efficiently and automatically discharge fried waste etc. to the outside. It is also possible to automate the balance between injection and discharge by automatically opening and closing the solenoid valve according to timer or sensor information.

  1 and 2 show Embodiment 1 of the present invention. FIG. 2 is a side view of the fryer 100 according to the first embodiment of the present invention. FIG. 1 shows a top view of the reservoir water layer 116. The clean water 114 is ejected from the nozzles 103, 104, 105, 106 through the valve 113, the deaerator 112, and the pipe 111. There are a plurality of nozzles arranged on the side surface of the reservoir water layer portion 116, and the ejected water flows 107, 108, 109, 110 form a water flow in the reservoir water layer portion 101. 2 which is a flyer side view of the embodiment of the present invention has an upper oil layer 115 and a lower water layer 116, and a liquid interface 117 exists due to a difference in specific gravity between them. Nozzles 103, 104, 105, 106 provided on the side surface of the storage tank water layer jet the water streams 107, 108, 109.110 slightly downward so as not to make the liquid boundary surface 117 greatly waved. The fried dregs 118 falling from the liquid interface 117 is deposited and deposited on the bottom of the inverted conical storage tank or the cylindrical dregs storage tank 102. When the predetermined amount of time or the amount of frying waste increases, the fresh water 114 is not always flowed, and the fresh water is ejected from the nozzle to guide the precipitated and accumulated fried waste to the waste reservoir 102. The water flow is a cylindrical waste reservoir 102. The fried residue is prevented from rolling up from the residue storage tank 102. During the specified time, when the amount of frying residue increases, the frying residue sensor 121 controls the water inlet valve 113 and the discharge valve 120 by a timer of a control unit (not shown). If the valves 113 and 120 are flow rate control electromagnetic valves, the flow rate is automatically controlled. At the time of water injection, the liquid boundary surface in the storage tank changes, but it can be detected by the liquid level sensor 121, and the water inlet valve 113 and the drain valve 120 are controlled to make the height of the liquid boundary surface 117 constant. I can do it. When the valves 113 and 120 are not flow control solenoid valves, manual adjustment and manual pouring / draining are possible.

FIGS. 3 and 4 show a second embodiment of the present invention in which the frying residue is removed by a rotor blade having fins in the storage tank water layer 101. For the functional explanation, the rotor blade 125 is simplified and has a structure that rotates 127 about the rotation shaft 126. When water is injected from the nozzle, the rotor blades 125 are rotated by the generated water flow. The rotor blades are arranged with a slight gap on the inverted conical surface of the reservoir water layer and rotate easily. Due to the rotation of the rotary blade 125, the fried residue can be actively dropped into the residue pool. In the explanatory diagrams of Example 1 and Example 2, the number of nozzles is four, and the water flow ejected from the nozzles is an example of a fan-shaped water flow shape. It is not limited to the fan shape, but is an example of a more efficient embodiment. The heaters shown in FIGS. 2 and 4 may be either electric or gas.

  The present invention realizes, at a low cost, discharge of fried debris that has fallen from an upper oil layer, which is a cooking layer, to a lower water layer, in a two-layer fryer having an aqueous layer and an oil layer. Since the flyer has a simple structure that does not have a driving structure such as a pump or a piping structure that serves as a circulation path, a low-cost two-layer fryer can be provided with a low failure frequency.

Solution

  The bottom of the storage tank has a dregs collection tank for collecting dregs, and the water flow due to water pressure such as tap water is ejected by providing a nozzle in the water layer near the bottom of the storage tank, thereby efficiently guiding the fried dregs to the dregs storage tank for precipitation. Can be discharged to the outside. Since it is a simple structure that does not have a drive structure such as a pump or a piping structure that serves as a circulation path, it is possible to realize a low-cost water-oil two-layer fryer with a low failure frequency.
