Description

Fryer using Oil and Water}

The present invention relates to a water-based fryer, and more specifically, by improving the configuration of the fuel ejection guide to maintain a uniform flame during gas combustion, thereby improving combustion efficiency and suppressing the generation of harmful exhaust gases due to incomplete combustion. It's about a breastfeeding fryer that allows you to do this.

In general, one of the representative cooking methods for meat, including fish and vegetables, is frying, and since it is not easy to cook at home, there is a trend of becoming specialized and large-scale.

For these fried dishes, a fryer is used that fills an oil tank heated with electricity or gas as a heat source, fills it with cooking oil, then puts the frying ingredients into it and allows it to fry for a certain period of time. A conventional fryer uses various wastes generated during the frying cooking process. Since the oil and fat components of animal origin settle on the inside bottom of the oil tank, the cook is inconvenienced by having to frequently insert a cooking utensil in the form of a strainer into the oil tank and remove the waste to the outside. In addition, the cooker must frequently insert a cooking utensil in the form of a strainer into the oil tank to remove the waste. As residues and oil solids cannot be discharged to the outside and are left unattended, they stick to the bottom of the oil tank or burn, making it difficult to maintain the freshness of the cooking oil and requiring frequent replacement. As accumulated animal oil components and frying residue burn, benzopyrene and It not only causes the generation of carcinogens harmful to the human body, but also increases the economic burden due to frequent replacement of cooking oil, and causes problems of environmental pollution due to increased emissions of waste cooking oil.

In order to solve the above problem, the difference in specific gravity between cooking oil (oil) and water is used. A water layer is located at the bottom of the fryer, and an oil layer made of cooking oil with a heater is formed on the upper side, thereby frying the ingredients into an oil layer. A breast-feeding fryer that allows cooking has been proposed.

In other words, in a water-feeding fryer, various frying residues, including trans fat, benzopyrene, and animal fats and oils generated by cooking oil heated in the combustion chamber, and wastes or frying by-products with a greater specific gravity than the animal fats and oils sink to the bottom of the water and close the discharge valve at the bottom. By allowing it to be discharged, the deterioration of the cooking oil can be slowed by preventing animal oil ingredients, including frying residues and by-products, from burning in the high-temperature cooking oil. As a result, the layer of animal fat accumulated as the cooking time is prolonged can be discharged using the discharge valve. Demand is gradually increasing due to the advantage of being able to discharge, increasing the freshness time of cooking oil and reducing oil consumption.

As a prior art, a water-based fryer has been proposed through Korean Patent Publication No. 10-2448049, and a configuration that prevents the water level from rising and maintains a constant cooling temperature of the water is disclosed.

As another prior art, a breast-feeding fryer disclosed in Korean Patent Publication No. 10-1667887 has been proposed, and claim 1 states that 'the upper surface is an open horizontal surface, and the lower surface is an inclined surface with a hole on the bottom surface; A frying oil container in which the area of the hole is smaller than the upper surface;

A heating oil passage provided to penetrate the oil sump to heat the oil inside the sump;

A gas burner having a metal fiber portion that supplies combustion heat to the heating passage;

Located below the oil sump, the upper surface portion having an exposed portion that is sealingly joined to the rim of the hole that serves as the outlet of the fluid from the oil sump, the lower surface portion that has a drain pipe, and the position of the exposed portion that is sealingly joined to the hole are preliminarily determined. An oil and water container including a side portion with an inspection window through which the boundary between oil and water is displayed on a horizontal surface below a predetermined length;

an interface sediment discharge pipe positioned horizontally to the oil and water interface to discharge the oil and water interface sediment layer; And a water supply pipe located between the interface sediment discharge pipe and the drain pipe,

In the oil and water container, a protruding space is formed on the upper part of the upper surface so that an air layer is filled when receiving oil and water along one or more sides forming the upper surface, and the lower surface forms an inclined surface so that the drain pipe is at the bottom, and the heating The flow path includes a first heating tube installed therein with a diffusion plate to diffuse combustion heat, and a second heating tube with a heat distribution plate installed therein,

The metal fiber part is inserted into one opening of the first heating tube toward the other opening, and the diffusion plate is installed inside the first heating tube at a predetermined distance from the metal fiber part,

The heat distribution plate includes a horizontal plate that divides the inside of the second heating tube into a first flow path located above the heat distribution plate and a second flow path located below the heat distribution plate; a vertical plate dividing the first flow path and the second flow path into left and right sides and having a plurality of openings having at least one vertical side arranged at predetermined intervals; and a plurality of combustion heat guide parts in contact with the vertical sides of the opening and arranged alternately in the left and right directions so as to be perpendicular to the vertical plate,

Among the plurality of combustion heat guide parts located in the first flow path, the combustion heat guide part adjacent to both ends of the vertical plate and the combustion heat guide part located in the second flow path have an area of 4/5 to 1/3 of the area of the combustion heat guide part. Branches form holes,

A blocking plate that allows combustion heat to flow into the first flow path is coupled to one end of the second heating tube, and a sealing plate that allows combustion heat flowing into the first flow path to flow into the second flow path is attached to the other end of the second heating tube. Combined, the diffusion plate is installed opposite to the metal fiber inside the first heating tube and is installed crosswise in the longitudinal direction of the first heating tube and has a plurality of through holes formed in the upper half with respect to the central horizontal line. A first diffusion plate in which the diameter of the through hole located is smaller than the diameter of the through hole located in the lower half; And a second diffuser installed to be spaced apart from the first diffusion plate, but installed across the longitudinal direction of the first heating tube, and having a plurality of through holes formed therein having a diameter smaller than the diameter of the through hole of the first diffusion plate at the corresponding position. It includes two diffusion plates, wherein the first diffusion plate and the second diffusion plate are connected to each other by a connecting member, and the connecting member connects the center of the first diffusion plate and the center of the second diffusion plate. a first connecting member; and a water-feeding fryer including a second connecting member connecting a portion of the outer portion of the first diffusion plate and a portion of the outer portion of the second diffuser plate.’ is disclosed.

However, the water-based fryer according to the prior art uses a gas burner, which requires an ideal mixture of oxygen and fuel gas. However, since it simply sucks in external air and ignites the fuel gas, it is difficult to form a uniform flame overall. Therefore, there was a serious problem of generating harmful gases such as soot or carbon monoxide due to incomplete combustion.

That is, looking at the water-based fryer of Patent Registration No. 10-2448049, a heat distribution plate is formed inside the heating tube, and when the heat supplied from the gas burner is supplied through the front of the first heating tube, a blocking plate is formed at the rear of the first heating tube. The blocking plate blocks the lower part of the blocking plate so that the heat flows upward, flows from the back to the front of the second heating tube through the first flow path located at the top of the heat distribution plate, and then flows to the front of the second heating tube. The flow changes in the sealing plate 320 covering the part and flows from the front to the back of the second heating pipe through the second flow path located at the bottom of the heat distribution plate. The heat that has arrived at the blocking plate area is now released to the outside through the open space through the guide play and exhaust pipe.

However, the water-based fryer according to the prior art was a gas burner type that ignites gas fuel to generate a heat source, so there was a problem in generating soot and harmful gases such as carbon monoxide and carbon dioxide due to incomplete combustion.

That is, the water-feeding fryer according to the prior art forms a first flow path and a second flow path based on a horizontal plate, and configures a plurality of combustion chamber guide parts so that the water flow from the rear to the front of the second heating tube through the first flow path is formed. The flow was changed from the sealing plate covering the front part of the second heating tube and flowed from the front to the back of the second heating tube through the second flow path, so the structure was complicated, making mass production, assembly, and maintenance difficult.

In addition, since the flame or heat flows in the order of the first passage at the top and the second passage at the bottom based on the horizontal plate, these first and second passages are connected to the plurality of combustion chamber guide parts in the process of propagating the flame or heat. Not only does it temporarily block the flow, causing a pulsation phenomenon, causing vibration or noise, but also exhaust gases harmful to the human body, such as carbon dioxide and carbon monoxide, resulting from incomplete combustion as fuel gas and oxygen are burned without sufficient mixing inside the heating tube. This has the disadvantage of lengthening cooking time and increasing fuel consumption due to the lowering of the temperature of the flame or heat due to incomplete combustion. Above all, there is a problem that it significantly deteriorates the cooking environment and threatens the health of the cook.

It is provided in proportion to the number. That is, since the air screw 57 in the present invention consists of six blades 57c, the gap between each blade 57c forms a swirl flow path 57s.

The operation of the breast-feeding fryer according to the present invention configured as described above will be described as follows.

First, a set amount of water is supplied and injected into the oil tank 20, and then the frying oil is also supplied and injected by a set amount. The oil and water are divided into an oil layer at the top and a water layer at the bottom due to the difference in specific gravity. is located.

Subsequently, when the gas burner 30 is driven, the gas burner 30 receives fuel gas and air and ignites the mixed gas by discharging it through an outlet (not marked).

Then, primary combustion occurs in the first combustion pipe portion 41 of the gas combustion pipe 40 connected to the gas burner 30, generating flame and heat and simultaneously generating unburned gas.

Such flame, heat, and unburned gas flow into the second combustion pipe portion 42 via the bending pipe portion 43 and have a vortex flow as they pass through the combustion damper 50.

That is, the plurality of air screws 57 constituting the combustion damper 50 installed inside the extension portion 57b are arranged in succession at a predetermined rotation angle to form a plurality of spiral swirl flow paths 57s. Accordingly, the flame, heat, and unburned gas flowing in through the first combustion pipe portion 41 have a vortex flow, and in particular, the unburned fuel gas and air that make up the unburned gas are uniformly mixed by the vortex flow. This results in complete combustion.

Finally, the exhaust gas completely burned in the second combustion pipe portion 42 is discharged to the exhaust chamber 12 via the retention exhaust plate 55, and the exhaust chamber 12 is provided with a heat shield plate 53. This blocks heat from being directly transmitted to the wall of the exhaust chamber 12, that is, the main body 10. In this way, the exhaust gas exhausted to the exhaust chamber 12 is discharged to the outside of the main body 10 through the exhaust hole 55a, and the exhaust gas exhausted outside the main body is disposed of through exhaust equipment (ventilator, etc.) installed in the galley. do.

Meanwhile, the present invention is not limited to the described embodiments, and can be used by changing the application area, and various modifications and variations can be made without departing from the spirit and scope of the present invention. It is self-evident to those with knowledge.
