A frying machine oil tank structure

Abstract

The present invention discloses an oil tank structure of a frying machine, comprising a base support (10) and an oil tank (1). The oil tank (1) is divided into a plurality of frying areas by a baffle plate (4). The oil return pipeline (11) pumps hot oil at the bottom of a high-temperature frying area (2) to a low-temperature frying area (3) through an oil pump (13), thereby accelerating the temperature rise of the oil in the low-temperature frying area (3). At the same time, the hot oil at the bottom of the low-temperature frying area (3) flows back through a connecting mechanism (9) to the vicinity of a heating pipe (6) provided in the high-temperature frying area (2), thereby reducing the oil temperature at the bottom of the high-temperature frying area (2), preventing residue from becoming mushy and affecting the taste of fried food. At the same time, together with a leaking plate (5), it is ensured that the oil temperature will not be too high to cause the food to become mushy. The oil temperature can be reduced, the power required by the heating pipe (6) can be saved, and emissions can be reduced. The oil temperature area is stable, and the food can be effectively prevented from becoming mushy.

Description

Technical Field

[0001] The invention relates to the technical field of automatic frying, and in particular to an oil tank structure of a frying machine. Background Art

[0002] Fried food is a popular delicacy. In order to ensure that the fried ingredients taste the best, the control of the oil temperature is relatively high. The optimal oil temperature for frying different ingredients is also different. Under the existing technology, it is rare to use one machine to fry several ingredients with different oil temperature requirements at the same time. If you don't pay attention to the temperature adjustment when frying the ingredients, the ingredients will be burnt.

[0003] A Chinese patent with a publication date of April 4, 2012 and a publication number of CN202179073U discloses a deep fryer, including a heater, a stirring device, and a lifting device, characterized in that one end of the heater is set as a stirring device, and the other end is set as a lifting device. The deep fryer is energy-efficient and closed, and has centralized temperature control, so that different areas in the pot body have different temperatures, but the molecules will accelerate irregular movement under the thermal effect. In fact, the deep fryer disclosed in the prior art cannot guarantee the different oil temperatures in different areas of the pot body or the time for the regionalization of the oil temperature to exist. Summary of the invention

[0004] The purpose of the present invention is to solve the problem that the frying machine in the prior art cannot use several zones of the same frying machine to fry foods with different oil temperature requirements at the same time, and to provide an oil tank structure of a frying machine. The oil tank is divided into several frying zones with different temperatures by a blocking plate, so that a variety of foods with different oil temperature requirements can be fried at the same time. The concept of live oil is proposed, and multiple sections of oil return pipelines are provided to enable hot oil in frying zones with different adjacent temperature gradients to flow from high temperature to low temperature, thereby preventing foods from being burnt and consuming less energy.

[0005] The technical solution adopted by the present invention to solve the above technical problems is a fryer oil tank structure, including a base bracket, the upper end of the base bracket supports the oil tank, the oil tank is divided into a plurality of frying areas with successively decreasing temperatures, and the bottoms of two frying areas with similar temperatures are connected; the base bracket is provided with an oil return pipeline, and the oil return pipeline is connected to the high-temperature frying area and the low-temperature frying area in sequence. Preferably, the base bracket is a bracket formed by welding a plurality of square steel pipes, which have square steel pipes of the same length, quantity and corresponding positions placed vertically on both sides of the bottom of the oil tank, and have horizontally arranged square steel pipes at the bottom that are connected one by one to the bottoms of the corresponding square steel pipes, so that the entire structure can be placed horizontally, and the oil tank is divided into two areas by a blocking plate, a high-temperature frying area and a low-temperature frying area, and a connecting mechanism is provided at the bottom of the two frying areas with different temperatures, so that the bottoms of the two frying areas are connected, and hot oil can flow in small amounts through this pipeline, and an oil return pipeline is provided on the base bracket, one end of the oil return pipeline is connected to the high-temperature frying area, and the other end is connected to the low-temperature frying area, so that the hot oil in the high-temperature frying area flows to the low-temperature frying area, and the hot oil in the low-temperature frying area is then returned to the high-temperature frying area through the connecting mechanism, so that the oil temperature of the two frying areas is always kept stable, and at the same time, the low-temperature frying area is heated up because the hot oil from the high-temperature frying area flows over, so less energy is consumed in heating the low-temperature frying area, which is energy-saving.

[0006] The baffle plate is arranged in the middle part of the oil tank, and the baffle plate extends in all directions to divide the oil tank into several frying areas. The frying areas at adjacent temperatures are connected by a connecting mechanism at the bottom, and a gap is arranged in the middle of the baffle plate. Preferably, the baffle plate is an axisymmetric structure, and a gap is arranged in the middle of the baffle plate. The gap is small at the upper end and large at the lower end, and the gap size transitions smoothly. The high-temperature frying area and the low-temperature frying area at adjacent temperatures are connected by a connecting mechanism at the bottom. The connecting mechanism can be a partition with small holes. The gap is arranged in the middle of the baffle plate to avoid the influence of the hot oil temperature of the high-temperature frying area and the hot oil temperature of the low-temperature frying area beyond the plan. The connecting mechanism connecting the bottoms of different frying areas can form a complete oil circuit, and then the required heating time per minute and the required flow rate of hot oil are calculated through simulation experiments.

[0007] The bottom of the oil tank is provided with a leak plate, which is connected to the inner wall of the oil tank on all sides, and the number of the oil return pipelines is the same as the number of the frying areas. Preferably, the bottom of the oil tank is provided with a leak plate, which is not in contact with the bottom surface of the oil tank, but is at a certain distance from the bottom surface of the oil tank. The leak plate is provided with neatly arranged slender openings, and the residues produced during frying fall into the space at the bottom of the leak plate through the openings. After the residues fall, they will continue to stay at the bottom of the leak plate because the leak plate is not blocked by the opening position. The oil return pipeline is divided into several, and the specific number is the same as the number of frying areas opened. Each oil return pipeline is connected in turn with a high-temperature frying area and a low-temperature frying area of ​​similar temperature, so that the high-temperature hot oil can be used to the greatest extent to reduce the energy required for heating the low-temperature frying area, which plays a role in energy saving and emission reduction and reduces costs.

[0008] The oil return pipeline connects the frying areas from high temperature to low temperature in sequence, one end of the oil return pipeline is connected to the bottom of the leak plate in the high temperature frying area, and the other end is connected to the top of the leak plate in the low temperature frying area. Preferably, one end of the oil return pipeline is connected to the bottom of the high temperature frying area, and the other end is connected to the top of the low temperature frying area, so that the hot oil in the high temperature frying area will take away the residues trapped at the bottom of the leak plate, pass through the oil return pipeline, and be removed by special equipment. The connection point of one end of the oil return pipeline connected to the low temperature frying area is higher than the surface of the hot oil to prevent reflux, so that the hot oil with higher temperature cannot leave the oil return pipeline in the first time.

[0009] An oil filter is provided in the middle of the oil return pipeline, and an oil pump is provided on one side of the oil filter. Preferably, an oil filter is provided in the middle of the oil return pipeline, and the oil filter filters and blocks the residues flowing through, and the clean hot oil is pumped to the low-temperature frying area through the oil pump on one side of the oil filter, and the excess low-temperature oil in the low-temperature frying area flows to the high-temperature frying area through the connecting mechanism, so that the oil flows while frying, and it is not easy to burn the food.

[0010] Each frying area of ​​the oil tank is provided with an independent heating rod, and the heating rods are evenly distributed at the bottom of the leak plate. Preferably, the oil tank is provided with a heating rod, and each frying area of ​​the heating rod controls the heating temperature separately. The heating rod is heated at the bottom of the leak plate. Due to the obstruction of the leak plate, it takes a process for the heated hot oil to enter the top of the leak plate, that is, it takes a little time for the hot oil contacted by the food to reach the same temperature as the hot oil at the bottom of the leak plate. This will prevent the hot oil contacted by the food from increasing in an instant and causing the food to become mushy. The heating rods are evenly distributed, so the heating effect is better.

[0011] The upper end surface of the oil tank is provided with an extension part, and the extension part is turned down in all directions, and the oil tank body is a hollow double-layer structure. Preferably, the upper end surface of the oil tank is turned outward to form a smooth transition, which plays a certain protective role, and the oil tank body is a hollow double-layer structure, and the air in the hollow part is used to isolate the oil temperature, so that the staff will not be burned when accidentally touching the oil tank.

[0012] The beneficial effects of the present invention are as follows: (1) the oil tank is divided into a plurality of different frying areas by the baffle plate, so that a plurality of food materials with different oil temperature requirements can be fried at the same time; (2) the hot oil is allowed to flow during frying through the oil return pipeline and the connecting mechanism, with cold oil flowing in and hot oil flowing out, so as to maintain the oil temperature of the food contact part and prevent the food from being burnt; (3) an oil filter is installed in the oil return pipeline to filter the residue and prevent the residue from making the hot oil burnt; (4) the oil return pipeline sequentially connects the frying areas with adjacent temperatures, so as to maximize the heat utilization of the hot oil and save energy and reduce emissions; (5) the oil tank is provided with a double-layer tank body, and a smooth transition is made at the upper end to protect the personal safety of the staff.

DETAILED DESCRIPTION

[0021] The specific implementation of the technical solution of the present invention is further described below through examples and in conjunction with the accompanying drawings.

[0022] Example 1

[0023] exist Figure 1 Figure 2 He 3 Figure 4 Figure 5In the embodiment 1 shown, a frying machine oil tank structure includes a base bracket 10, which is a bracket formed by welding a plurality of square steel pipes. Square steel pipes of the same length and quantity and corresponding positions are vertically placed on both sides of the bottom of the oil tank 1. The bottom has horizontally arranged square steel pipes connected one by one to the bottom of the corresponding square steel pipes, so that the whole structure can be placed horizontally. A baffle plate 4 is arranged in the middle of the oil tank 1. The baffle plate 4 divides the frying area into two parts, wherein the frying area on the left is a low-temperature frying area 3, and the frying area on the right is a high-temperature frying area 2. A gap 8 is arranged in the middle of the baffle plate 4, wherein the gap 8 is small at the upper end and large at the lower end, and the transition is smooth A leak plate 5 is provided at the bottom of the oil tank 1, and the lower end of the barrier plate 4 is fixedly connected to the upper surface of the leak plate 5. An elongated opening is provided on the leak plate 5, and the openings are arranged neatly and densely. The food contacts the hot oil above the leak plate 5. There is a space at the bottom of the leak plate 5. The residue in the hot oil sinks into the space below the leak plate 5 through the leak plate 5. An oil return pipeline 11 is provided at the bottom of the oil tank 1. The left end of the oil return pipeline 11 is connected to the side wall of the low-temperature frying area 3, and the connection position is higher than the hot oil surface. The right end of the oil return pipeline 11 is connected to the bottom of the high-temperature frying area 2. An oil pump 13 is provided on the bottom of the high-temperature frying area 2 and the base bracket 10. The oil pump 13 pumps the hot oil and residue at the bottom of the leak plate 5 of the high-temperature frying area 2. The dregs are pumped into the return oil pipeline 11, and flow into the low-temperature frying area 3 from the side wall of the bottom temperature frying area 3 and mix in the low-temperature oil, which increases the oil temperature inside the low-temperature frying area 3, can reduce the energy supply, save energy and reduce emissions, and an oil filter 12 is also provided in the middle of the return oil pipeline 11 to filter the dregs cleanly, so that the hot oil flowing into the low-temperature frying area 3 is clean, and the quality of the hot oil inside the low-temperature frying area 3 is maintained. A connecting mechanism 9 is provided at the bottom of the baffle plate 4, and the connecting mechanism 9 is a partition 14, which is vertically arranged to divide the space into two at the bottom of the leak plate 5. A hole is provided in the middle part of the bottom end of the partition 14, and the hot oil pumped into the low-temperature frying area 3 makes the low-temperature oil The hot oil in the frying area 3 increases, while the hot oil in the high-temperature frying area 2 decreases. The excess hot oil in the low-temperature frying area 3 flows along the holes set in the partition 14 to the bottom of the leaking plate 5 of the high-temperature frying area 2. Independent heating rods 6 are set below the leaking plates 5 of the high-temperature frying area 2 and the low-temperature frying area 3. The heating rods 6 are evenly distributed, so that the oil temperature at each position of the frying area tends to be the same, heating is faster and energy-saving and emission reduction is reduced. At the same time, the hot oil at the bottom of the low-temperature frying area 3 flows to the bottom of the high-temperature frying area 2, so that the hot oil at the bottom of the leaking plate 5 of the high-temperature frying area 2 flows, and the hot oil temperature near the heating rods 6 is neutralized to prevent the slag from being fried at the bottom of the high-temperature frying area 2 and affecting the taste of the food after frying. The tank body of the oil tank 1 adopts a double-layer structure with a gap in the middle to prevent the outer side of the side wall of the oil tank 1 from directly contacting the hot oil and becoming hot, burning the staff who accidentally touch it. An extension part 7 is also set at the upper end of the oil tank 1, and the extension part 7 rolls outward to make the upper end of the oil tank 1 smooth and round, and will not cut the staff who accidentally touch it, playing a protective role.

[0024] Example 2

[0025] exist Figure 6 Figure 7 In the illustrated embodiment 2, the oil tank 1 is divided into four frying areas, and the oil temperatures are, from high to low, the first frying area 15, the second frying area 16, the third frying area 17, and the fourth frying area 18. A first oil return pipeline 20 is provided to connect the bottom of the first frying area 15 and the upper end of the side wall of the second frying area 16; a second oil return pipeline 21 is provided to connect the bottom of the second frying area 16 and the upper end of the side wall of the third frying area 17; a third oil return pipeline 22 is provided to connect the bottom of the third frying area 17 and the upper end of the side wall of the fourth frying area 18; a fourth oil return pipeline 23 is provided to connect the bottom of the fourth frying area 18 and the upper end of the side wall of the first frying area. A partition 14 is provided at the bottom of each baffle plate 4, so that the frying area with the highest temperature is buffered by the cooler hot oil, further preventing the oil temperature from being too high and the food from being fried and burnt. The rest is the same as in embodiment 1.

[0026] The working principle of a frying machine oil tank structure of the present invention is as follows:

[0027] Taking the frying machine oil tank structure with only two frying areas as an example, first, both frying areas are filled with edible oil of the same horizontal plane, and be careful not to let the upper surface of the edible oil be higher than the end of the return oil pipeline 11 fixed to the side wall of the low-temperature frying area 3. The heating rod 6 set in the high-temperature frying area 2 starts to heat first according to the set program, and the oil pump 13 starts to work at the same time. The oil at the bottom of the high-temperature frying area 2 flows to the side wall of the low-temperature frying area 3 through the return oil pipeline 11, and then mixes with the oil inside the low-temperature frying area 3. The oil at the bottom of the low-temperature frying area 3 flows to the bottom of the high-temperature frying area 2 through the connecting mechanism 9. The heating rod 6 set in the high-temperature frying area 2 is quickly heated, and this reciprocating is repeated. Therefore, when the heating rod 6 set in the low-temperature frying area 3 does not work at the beginning, the oil temperature can gradually rise until the oil temperature in the high-temperature frying area 2 meets the bottom oil temperature of the frying food. The bottom oil temperature food can be fried in the high-temperature frying area 2 first, but it cannot be fried in the high-temperature frying area 2 for a long time. The temperature of the high-temperature frying area 2 slowly rises. At this time, the heating rod 6 set in the low-temperature frying area 3 also starts to work. Such a design of the return oil pipeline 11 can be In order to reduce the heating time of the heating rod 6, energy conservation and emission reduction, as time goes by, the high-temperature frying area 2 fries high-oil-temperature ingredients, and the low-temperature frying area 3 fries low-temperature ingredients. When the required oil temperature of the low-temperature frying area 3 is reached, the heating rod 6 provided therein can be heated at intervals or the output power can be reduced. The heating rod 6 provided in the high-temperature frying area 3 continues to heat, but the output power is also reduced. During frying, dregs will be generated in the frying area 2, and the dregs will sink to the bottom of the high-temperature frying area 2 through the opening provided by the leak plate 5. The dregs will easily become mushy under high-temperature conditions. The return oil pipeline 11 pumps the hot oil and the residue into the return oil pipeline 11 at the bottom of the high-temperature frying area 2, and the oil flows through the oil filter 12 arranged in the middle of the return oil pipeline 11 to filter the residue, so that the oil flowing into the low-temperature frying area 3 is clean and residue-free. When the heating tube 6 in the frying area is heated, the leak plate 5 is above the hot oil in the space where the heating rod 6 is located, and plays a blocking role. Therefore, even if the heating tube 6 is set to too large a power due to an error, the increase in oil temperature can be alleviated as the hot oil in the frying area is exchanged, and the food will not be easily burnt.
