Description

Technical Field

[0001] The present invention relates to the field of food processing, and particularly to a boiling stove. Background Art

[0002] When existing fans boiling stoves for industrial production or boiling stoves for food processing are in use, a more environmentally friendly gas stove is used to boil food, which is usually a kitchen appliance that uses gas fuels such as liquefied petroleum gas, artificial gas, and natural gas for direct fire heating. However, currently, the stove usually has a burner arranged at the bottom of the pot body to heat the bottom of the pot. During the food processing, as the food needs to be in different firepower states at different stages during the ripening process, it is necessary to control the boiling state of the water body in different areas of the pot body. Usually, it is achieved by adjusting the combustion state of the burner in the bottom area of the pot. The flame diffuses and flows around the relatively smooth bottom of the pot, affecting each other, and it is impossible to achieve stable control of the combustion state in this area. Its heating degree cannot be accurately controlled. At the same time, with this structure, a large amount of heat is carried away by the flue gas, and its thermal efficiency is low, resulting in energy waste. Summary of the Invention

[0003] The purpose of the present invention is to provide a boiling stove in view of the deficiencies of the prior art. It has a simple and compact structure, can facilitate the realization of different degrees of heating adjustment and control of at least two heating areas, and at the same time has a high thermal efficiency and can save energy.

[0004] The purpose of the present invention is achieved as follows: A boiling stove, comprising:

[0005] A stove body;

[0006] A burner assembly, including at least two burners arranged along a first direction;

[0007] A pot body, supported on the stove body. A plurality of heat conduction grooves are arranged at intervals on the outer surface of the bottom wall of the pot body above the burner assembly, and the plurality of heat conduction grooves are arranged along the first direction. The smoke exhaust holes of each heat conduction groove are connected to a chimney through a smoke pipe, and the chimney is provided with an air extraction device for promoting the flow of flue gas.

[0008] The bottom wall of the pot body has a waveform contour extending along the first direction, and the heat conduction grooves are formed in the wave valleys of the outer surface of the bottom wall.

[0009] A lining plate is arranged inside the pot body, and both sides of the lining plate are connected to the inner wall of the pot body. A sandwich space is formed between the lining plate and the bottom wall of the pot body. The smoke pipe is arranged in the sandwich space, and the lining plate is provided with water passing holes.

[0010] The starting section of the lining plate is arranged in a gradually descending manner.

[0011] The exhaust holes of the first of two adjacent heat-conducting grooves are located in the first side section, and the exhaust holes of the second heat-conducting groove are correspondingly arranged in the second side section opposite to the first side section. The exhaust holes of multiple heat-conducting grooves are arranged alternately.

[0012] The smoke pipe includes a primary smoke pipe section and a secondary smoke pipe section. The exhaust holes of the heat-conducting grooves are connected to the primary smoke pipe section. The primary smoke pipe section includes a horizontally extending pipe section and a vertically extending pipe section that are connected. The vertically extending pipe section is connected to the exhaust holes, and the outlet end of the horizontally extending pipe section is connected to the secondary smoke pipe section. The secondary smoke pipe section is communicated with the chimney; the extending directions of the horizontally extending pipe sections of adjacent primary smoke pipe sections are opposite.

[0013] The bottom wall of the pot body includes a plurality of heat exchange elements arranged in an array. Each heat exchange element has:

[0014] A bent portion that encloses to form a heat-conducting groove with the opening facing downward;

[0015] A horizontally extending portion connected to the first side of the bent portion;

[0016] Among them, in adjacent heat exchange elements, the upper heat exchange element is connected to the second side of the bent portion of the lower heat exchange element through the horizontally extending portion;

[0017] The second side of the bent portion of the heat exchange element at the head of the array and the first side of the bent portion of the heat exchange element at the end are respectively connected to the pot body.

[0018] At least one notch end of the heat-conducting groove is provided with a side sealing plate, and the groove section of the heat-conducting groove corresponding to the exhaust hole is provided with a lower sealing plate. A smoke exhaust passage is left between the lower sealing plate and the bottom of the heat-conducting groove.

[0019] It further includes a gas supply mechanism. The gas supply mechanism includes a main intake pipe and a plurality of branch connecting pipes. Each branch connecting pipe is communicated with the main intake pipe, and a gas flow regulating valve is provided on each branch connecting pipe. The output ends of each branch connecting pipe are respectively connected to the burner; the burner is a grate burner, and the long axis direction of the grate of the burner is perpendicular to the first direction.

[0020] A partition is provided in the pot body. The partition divides the heating area in the pot body into a first heating section and a second heating section arranged in sequence along the material flow direction. A material passing gap is left between the lower part of the partition and the bottom wall of the pot body.

[0021] With the above solution, the beneficial effects are as follows. For the heating area corresponding to each burner, the difference in the corresponding burner can be controlled, and then the difference in the firepower can be controlled. A plurality of heat conduction grooves are arranged on the bottom wall of the pot body. The bottom wall of the pot body is uneven, having a large heat exchange area, making the contact between the flame and the bottom of the pot more sufficient, which can increase the heat exchange efficiency. At the same time, the uneven structure can limit the diffusion of the flame and flue gas in the first direction. After the flame diffuses more into the heat conduction grooves, through suction, it can continuously flow and diffuse along the extension direction of the heat conduction grooves, enabling the flue gas to flow in the path perpendicular to the first direction for heat exchange. Since the diffusion of the flame and flue gas in the first direction is blocked, the heating conditions of the corresponding bottom walls by different burners in different regions in the first direction are relatively independent, and their mutual influence is small. This can enable the pot body to form heating areas with relatively large differences, and different stages of material processing can be implemented. For example, in the process of processing vermicelli, at least two regions with different heating degrees are required. The stage of feeding the paste-like material requires a smaller firepower to shape the slurry. Excessive heating will cause the slurry just entering the pot body to boil and disperse. After the shaping is completed, a heating state with a larger firepower is required to accelerate the ripening of the preliminarily shaped vermicelli. By adopting the present invention, it is convenient to realize the different-degree heating adjustment and control of at least two heating areas, and at the same time has a high thermal efficiency, which can save energy.

[0032] In the description of this specification, the description of reference terms such as "one embodiment", "some embodiments", "example", "specific example", or "some examples", etc. means that the specific features, structures, materials, or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present invention.

In addition, without contradiction, those skilled in the art can combine and combine the different embodiments or examples described in this specification and the features of different embodiments or examples.

[0033] See Figures 1 to 5 , an embodiment of a cooking stove, the cooking stove includes a stove body 101, a burner assembly 102, and a pot body 104. The stove body 101 can be made of stainless steel, having good corrosion resistance and high temperature resistance, and serves as the supporting main body of the entire cooking stove; the size of the stove body 101 can be customized according to actual needs to adapt to different scales of cooking requirements, which is not limited in this embodiment.

[0034] The burner assembly 102 can be arranged inside the stove body 101 and integrated with the stove body, or can be placed under the pot body 104, and includes at least two burners 103 arranged in a first direction. The first direction can be the material moving direction. For example, in a rectangular pot body 104, its length direction can be the first direction, and the material moves in this direction and can undergo processes such as heat setting and ripening. The burner 103 can be a gas, liquid, or solid burner 103. Preferably, a gas burner 103 is used, using gases such as natural gas and liquefied petroleum gas as fuel. The gas fuel burner 103 has advantages such as high combustion efficiency, good stability, low pollutant emissions, clean combustion, easy control, rapid startup and shutdown, and convenient detection and maintenance. The burner 103 can be a grate-type burner 103, and the long axis direction of the grate of the burner 103 is perpendicular to the first direction, and it can adapt to the arrangement of the heat conduction grooves 105 and can heat the heat conduction grooves 105.

[0035] The pot body 104 is supported on the stove body 101 and located above the burner assembly 102. A plurality of heat conduction grooves 105 located above the burner assembly 102 are arranged at intervals on the outer surface of the bottom wall of the pot body 104, and the plurality of heat conduction grooves 105 are arranged along a first direction. The smoke exhaust holes 119 of each heat conduction groove 105 are connected to the chimney 107 through a smoke pipe 106, and the chimney 107 is provided with an air extraction device 108 for promoting the flow of flue gas. The air extraction device 108 can be a fan or an ejector. By means of the air extraction device 108, the flue gas is sucked from the heat conduction groove 105 through the smoke pipe 106 into the chimney 107, which can enable the flame to continuously flow on the groove wall of the heat conduction groove 105. A water supply pipe 131 can be arranged at the upstream end of the pot body 104. Through the water supply pipe 131, water can be supplied, the temperature can be controlled by water supply at the same time, the overflow of the water body can be realized by continuous water supply, and the cooked material can be taken away to realize discharging. An outlet 132 can be arranged at the downstream end of the pot body 104 in the first direction to facilitate automatic feeding.

[0036] It can be understood that at least two burners 103 are arranged along the first direction. For the heating areas corresponding to each burner 103, the heating degree can be controlled by controlling the firepower of the corresponding burner 103. A plurality of heat conduction grooves 105 are arranged on the bottom wall of the pot body 104. The bottom wall of the pot body 104 is uneven, having a large heat exchange area, making the contact between the flame and the bottom of the pot more sufficient, which can increase the heat exchange efficiency. At the same time, the uneven structure can limit the diffusion of the flame and flue gas in the first direction. After the flame diffuses more into the heat conduction groove 105 and is sucked, it can continuously flow and diffuse along the extension direction of the heat conduction groove 105, enabling the flue gas on the path perpendicular to the first direction to continuously flow for heat exchange. Since the diffusion of the flame and flue gas in the first direction is blocked, the heating conditions of the bottom walls corresponding to different burners 103 in the first direction are relatively independent, and their mutual influence is small, enabling the pot body 104 to form heating areas with relatively large differences, and different stages of material processing can be implemented. For example, in the process of processing vermicelli, at least two areas with different heating degrees are required. The stage of putting the paste-like material into vermicelli requires a small firepower to shape the slurry. Excessive heating will cause the slurry just entering the pot body 104 to boil and disperse. After the shaping is completed, a heating state with a large firepower is required to accelerate the ripening of the preliminarily shaped vermicelli. By adopting the present invention, it is convenient to adjust and control the heating intensities of at least two heating areas with different degrees, and at the same time, it has a high thermal efficiency and can save energy.

[0037] In some embodiments, the bottom wall of the pot body 104 has a waveform profile extending in a first direction, and heat conduction grooves 105 are formed in the troughs of the outer surface of the bottom wall. The waveform of the waveform profile may include a sine waveform, a square waveform, a triangular waveform, a rectangular waveform, or an irregular curve waveform. The waveform profile forms alternating convex and concave portions on both the inner and outer surfaces of the bottom wall, which can have a large heat exchange area. It can respectively exchange heat with the medium in the pot body 104, such as water, oil, etc. The outer surface of the bottom wall has a large heat exchange area, can have a large heat exchange area with the flame, and can achieve a large heat exchange efficiency. By adopting the waveform profile, the bottom wall can be formed by continuously bending a plate with equal thickness or splicing. On the basis of having a large heat exchange efficiency, it is convenient for processing and can save materials.

[0038] In some embodiments, the bottom wall of the pot body 104 includes a plurality of heat exchange members 116 arranged in an array. Each heat exchange member 116 has a bent portion 117 and a laterally extending portion 118: the bent portion 117 encloses to form a heat conduction groove 105 with an opening facing downwards; the laterally extending portion 118 is connected to the first side of the bent portion 117 to form a convex portion; wherein, in the adjacent heat exchange members 116, the upper heat exchange member is connected to the second side of the bent portion 117 of the lower heat exchange member 116 through the laterally extending portion 118; the second side of the bent portion 117 of the heat exchange member 116 at the head of the array and the first side of the bent portion 117 of the heat exchange member 116 at the end are respectively connected to the pot body 104. By adopting this method, the bottom wall part of the pot body can be formed by splicing a plurality of heat exchange members 116, which can reduce the requirements for processing equipment. At the same time, this method is also convenient for the installation operation of the smoke pipe 106, such as drilling, welding, etc.

[0039] In some embodiments, the smoke exhaust holes 119 of the first heat conduction groove 105 in two adjacent heat conduction grooves 105 are located in the first side section, and the smoke exhaust holes 119 of the second heat conduction groove 105 are correspondingly arranged in the second side section opposite to the first side section. The smoke exhaust holes 119 of a plurality of heat conduction grooves 105 are arranged alternately. By adopting this method, since the temperature of the flue gas gradually decreases as it travels in the smoke pipe 106, the water body in the pot body 104 can be made more uniform in the left-right direction through the alternating arrangement.

[0040] In some embodiments, the smoke pipe includes a primary smoke pipe section and a secondary smoke pipe section. The exhaust hole 119 of the heat conduction groove 105 is connected to the primary smoke pipe section 120; each primary smoke pipe section 120 includes a horizontally connected pipe section 121 and a vertically connected pipe section 122, where the vertically connected pipe section 122 is connected to the exhaust hole 119, and the outlet end of the horizontally connected pipe section 121 is connected to the secondary smoke pipe section 123, and the secondary smoke pipe section 123 is communicated with the chimney 107; the extending directions of the horizontally connected pipe sections 121 of adjacent primary smoke pipe sections 120 are opposite. In this way, the flue gas in the smoke pipe 106 can move longitudinally and horizontally, can exchange heat at different heights and widths of the water body, the flue gas has a large travel distance and can have a large heat exchange area, and the waste heat is recovered through the smoke pipe 106, improving the thermal energy utilization rate and achieving an energy-saving effect.

[0041] In some embodiments, at least one notch end of the heat conduction groove 105 is provided with a side sealing plate 124. Preferably, side sealing plates 124 are provided at both notch ends of the guiding groove 105. The heat conduction groove 105 is provided with a bottom sealing plate 125 at the groove section corresponding to the exhaust hole 119. A smoke exhaust channel 126 is left between the bottom sealing plate 125 and the bottom of the heat conduction groove 125. In this way, the negative pressure provided by the smoke pipe 106 can suck the flue gas along the groove extension direction as much as possible, and can have a good suction effect. The side sealing plate 124 is provided to slow down or avoid more air entering laterally in the groove section corresponding to the exhaust hole 119 of the guiding groove, and to avoid pressure damage as much as possible. A horizontal negative pressure area can be formed in the part of the heat conduction groove 105 in the pipe orifice area, and the flue gas can be continuously sucked in the extending direction of the heat conduction groove 105, so that the flue gas in the entire heat conduction groove 105 can be sucked away.

[0042] In some embodiments, a gas supply mechanism 127 is further included. The gas supply mechanism 127 includes a main intake pipe 128 and a plurality of branch connecting pipes 129. Each branch connecting pipe 129 is communicated with the main intake pipe 128, and a gas flow regulating valve 130 is provided on each branch connecting pipe 129. Each gas flow regulating valve 130 can be installed on the side wall of the stove body 101. The fuel feeding amount of the supplied fuel can be controlled through the flow regulating valve, and then the firepower can be controlled. The output ends of each branch connecting pipe 129 are respectively connected to the burner 103.

[0043] In some embodiments, a partition plate 109 is provided inside the pot body 104. The partition plate 109 divides the heating area inside the pot body 104 into a first heating section 110 and a second heating section 111 arranged in sequence along the material flow direction. A material passing gap 112 is left between the lower part of the partition plate 109 and the bottom wall of the pot body 104. The partition plate 109 can be used to divide the heating area, limit the water body exchange intensity between different heating sections in the pot body 104, make the heating degrees of different heating sections tend to be different, and can limit the food cooked in different heating sections. For example, in the processing of vermicelli, when the vermicelli comes out of the wire leakage head and continuously swings and falls into the first heating area, after being cooked and ripened by the boiling water and gas in this area, it enters the second heating section 111 through the material passing gap 112 between the lower part of the partition plate 109 and the bottom wall of the pot body 104, is further cooked and ripened and floats up. The floating vermicelli is limited by the partition plate 109 and cannot enter the first heating section 110, so as not to interfere with the powder feeding operation in the first heating section 110. Through the partition plate 109, the vermicelli can be cooked and ripened according to the heating in different stages, and prevent it from tumbling and scurrying around in the water flow in the pot body 104.

[0044] In some embodiments, a lining plate 113 is provided inside the pot body 104. Both sides of it are connected to the inner wall of the pot body 104. This connection can adopt fixed connection methods such as welding and integral molding, or can be connected in a detachable manner, such as bolt connection or snap connection. A sandwich space 114 is formed between the lining plate 113 and the bottom wall of the pot body 104. The sandwich space 114 enters the water body through a water passing hole 115; the smoke pipe 106 is arranged in the sandwich space 114. The smoke pipe 106 can exchange heat with the water body entering the sandwich space 114. The lining plate 113 is provided with a water passing hole 115. Through the water passing hole 115, the flow and exchange of water bodies and gases on both sides of the lining plate 113 can be realized. It can be understood that by setting the lining plate 113, the pot body 104 can be spaced from the food through the sandwich. The food processed in the pot body 104 cannot settle to the bottom of the pot, but settles on the lining plate 113, and there will be no phenomenon of sticking and gelatinization on the bottom wall of the pot. When the bottom wall of the pot is uneven, it can prevent the food from settling in the gaps and the movement hindrance of the food moving in the pot body 104.

[0045] Furthermore, the starting section of the lining plate 113 is arranged in a gradually decreasing manner. The starting section of the lining plate 113 can be arranged in a flat inclined manner or by means of arc transition; the burner 103 is a grate burner 103, and the long axis direction of the burner grate of the burner 103 is perpendicular to the first direction. It can be understood that during the process of industrial processing of food, feeding is usually carried out in one area of the pot body 104 based on gravity. In this way of feeding, the just-fed materials are likely to stack in the vertical direction, forming phenomena such as adhesion. If the pasty slurry cannot be evenly spread out immediately after entering the pot body 104, it is easy to form lumps; by setting the lining plate 113, the slurry gradually matures and takes shape after entering the water body. When the slurry at the lower position contacts the starting section of the lining plate 113, with the gradually decreasing structure, under the influence of gravity, the vertical materials gradually turn horizontal and gradually slide away, avoiding accumulation at this place.

[0046] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention is also intended to include these changes and modifications.
