Description

Technical Field

[0001] The present invention relates to the technical field of chili oil extraction, and particularly to a chili oil extraction and purification device. Background Art

[0002] As an essential flavor oil in domestic food culture, the food prepared with the chili oil is smooth, fragrant and delicious. As the main equipment for chili oil production, the chili oil extraction system usually produces chili oil in the form of stirring and boiling. However, the chili oil produced by the conventional industrial boiling method usually has a relatively soft taste, that is, the so-called "industrial flavor" in popular terms, and does not have the strong aroma similar to that of traditional restaurants.

[0003] When traditional restaurants boil chili oil, the oil materials are generally stir-fried (the stir-frying of chili oil in traditional small pots is different from that in industry. In industry, most oil materials are placed in a pot and stirred by a stirring device, while traditional restaurants usually stir-fry chili oil in the conventional sense, that is, the oil materials are repeatedly and briefly contacted with the high-temperature bottom of the pot for frying, and the principle of stir-frying chili oil is carried out), and a certain degree of oxidation (during the process of stir-frying the oil materials, the chili oil materials are exposed to the air for a certain degree of oxidation) further enhances the strong aroma of the chili oil.

[0004] However, these are not available in the preparation process of industrial chili oil. In the industrial preparation process, traditional frying pans cannot meet the production requirements of large industrial volumes. Because of the large volume of oil materials, (1) it is very difficult to stir-fry a huge volume of oil materials (the process of stir-frying can make the elements inside the raw materials of chili oil fully integrate into the oil materials and improve the rigid taste of the materials through short-term high-temperature contact with the materials, and this process is very important for the taste), (2) it is very difficult to ensure the uniformity and sufficiency of stir-frying for large industrial volumes of red, (3) in addition, the pot used in industrial preparation often adopts a closed structure, so the oil materials are usually boiled in an oxygen-free environment, resulting in it being difficult to produce the taste of traditional restaurants in industry. In view of this, the industry needs a chili oil production device that can stir-fry a large volume of chili oil evenly and sufficiently and can oxidize the stir-fried chili oil to a certain extent during the stir-frying process to produce chili oil with excellent taste and improve the market competitiveness of chili oil.

[0005] At the same time, the traditional chili oil purification device lacks corresponding designs for energy conservation and emission reduction, and lacks means for carbon emission reduction. As a device for preparing oil materials, corresponding designs for energy conservation and emission reduction are essential. Summary of the Invention

[0006] The purpose of the present invention is to provide a chili oil extraction and purification device to solve the above problems.

[0007] The present invention is achieved through the following technical solutions:

[0008] Generally, a chili oil extraction and purification device includes a boiling pot, an air supply device, an oil residue filter, and an oil storage tank. The boiling pot is provided with a housing, inside which a rotor and a driving unit are arranged. The housing is also provided with an air inlet pipe that communicates with the air supply device. The boiling pot stir-fries materials. After the materials are stir-fried, they are fed into the oil residue filter through a pipe at the bottom of the boiling pot. The oil residue filter separates the materials. The chili oil is separated by the oil residue filter and is fed into the oil storage tank for storage through a pipe. Air is fed into the frying pot through the air supply device, and the air intake volume can be controlled by the air supply device. It can ensure that the materials stir-fried in the boiling pot can be oxidized during the frying process, and the degree of oxidation can be ensured by the air intake volume, so as to ensure that the fried chili oil reaches the best taste. After the fried chili oil is processed, the chili and some auxiliary raw materials for enhancing the taste in the chili oil are filtered out by a separation device, and the filtered chili oil is stored in the chili oil storage tank for preservation.

[0009] Preferably, the rotor is provided with a rotating shaft that extends vertically downward. A paddle pump impeller is fixed to the lower end of the rotating shaft, and a centrifugal wheel is also fixed to the upper end thereof. A rotating pipe is sleeved on the outer circumference of the paddle pump impeller, and a spiral blade is arranged at the bottom of the outer side of the rotating pipe. The spiral blade is located at the bottom of the reflux interlayer. By arranging the paddle pump impeller below the rotating shaft of the rotor, when the rotating shaft rotates, the oil material at the bottom of the boiling pot can be pumped upward. By arranging the centrifugal wheel on the rotating shaft above the paddle pump impeller and sleeving the rotating pipe on the outer circumference of the paddle pump impeller (the centrifugal wheel is connected to the upper end of the rotating pipe), the paddle pump impeller below and the centrifugal wheel above can be kept rotating synchronously. While the paddle pump impeller below pumps the oil material upward, the centrifugal wheel above centrifuges the oil material to the surrounding circumference, enabling the oil material to spread to the surrounding circumference like a tsunami wave inside the boiling pot, thus explaining the name of the present invention: a chili oil extraction and purification device, which can be understood as a device that simulates tsunami waves to stir-fry chili oil to increase the aroma.

[0010] Preferably, the bottom of the shell of the boiling pot is a circular depression. The upper edge of the circular depression extends vertically upward to form a first extension part. The upper edge of the first extension part extends obliquely upward to form a second extension part. The upper edge of the second extension part extends vertically upward to form a third extension part. The upper edge of the third extension part is closed by a shell cover. By setting the bottom of the shell of the boiling pot as a circular depression, when the rotor rotating pipe rotates, the spiral fins fixed on the outside rotate synchronously, and the oil placed inside the boiling pot and outside the rotating pipe is pumped out circumferentially downward. The oil pumped out downward flushes the chili oil raw materials deposited at the bottom of the shell, causing the raw materials to flow toward the middle position of the circular depression of the shell. During this process, the paddle pumps arranged inside the rotating pipe can pump the chili oil raw materials in the middle upward, and diffuse them around through the centrifugal wheel above the paddle pumps, and pump the diffused oil to flow above the second extension part. The second extension part is similar to the converging opening on the upper side of a funnel. The oil diffused to the upper side of the second extension part will flow back to the interlayer position between the rotating pipe of the rotor and the first extension part, causing the oil to repeat the above process. During the process of the rotor rotating independently, the rotor cooperates with the circular depression bottom of the shell, the first extension part, and the second extension part to complete the repeated frying of the oil. Finally, by setting a shell cover at the upper end of the shell to close the boiling pot, it can prevent the oil from overflowing during the frying process.

[0011] Preferably, the shell cover is circular. An annular ventilation pipe is laid and fixed on the shell cover. The annular ventilation pipe is concentric with the shell cover. The connection part between the annular ventilation pipe and the shell cover forms an annular connection part. The annular connection part is provided with an annular ventilation pipe and an annular ventilation gap inside the shell. An air inlet pipe is connected to the outside of the annular pipe. The air inlet pipe introduces air into the boiling pot through a connected air supply device. An exhaust pipe is also connected to the outside of the shell. By laying and fixing the annular ventilation pipe concentric with the circular cover and opening an annular ventilation gap at the annular connection part between the annular ventilation pipe and the shell cover, the annular ventilation pipe is connected to the inside of the boiling pot. By connecting an air inlet pipe to the annular ventilation pipe and connecting an air supply device to the other side of the air inlet pipe, the air supply device can introduce food-grade air into the frying pot. When the air inlet pipe introduces air into the annular ventilation pipe, the air will quickly fill the inside of the pipe. The air filled into the pipe then enters the boiling pot through the annular ventilation gap. At the same time, the oil in the boiling pot diffuses circumferentially through the rotor. During this process, it just coincides with the oxygen ejected from the annular ventilation gap, enabling the oxygen in the air to contact the oil efficiently. The exhaust pipe provided separately on the shell is used to reduce the gas pressure in the boiling pot and prevent dangerous situations from occurring.

[0012] Preferably, the rotating shaft passes through a circular hole arranged in the middle of the shell cover and is connected to a rotating shaft of a driving unit arranged on the upper part of the shell. The rotation of the rotating shaft can drive the paddle pump blades and the centrifugal wheel to rotate. The paddle pump blades can drive the material in the whistling pot to spray upward, and the centrifugal wheel can drive the material to diffuse circumferentially to the upper side of the second extension part for flow. The rotating shaft is connected to the upper driving unit by passing through the circular hole in the middle of the shell cover. The rotating shaft thereby obtains rotational power to drive the paddle pump blades arranged at the bottom of the rotating shaft to rotate, so that the bottom oil is pumped upward. The oil pumped upward passes through the centrifugal action of the centrifugal wheel, and the oil flows back to the upper side of the second extension part of the shell.

[0013] Preferably, the circumferential side of the paddle pump blade is connected to the inner bottom of the rotating tube, the rotating tube is coaxial with the rotating shaft, the upper edge of the rotating tube extends obliquely upward to form a fourth extension portion, and the upper inner end of the fourth extension portion is connected to the bottom of the blade of the centrifugal wheel; the inner wall of the shell formed by the first extension portion of the shell and the second extension portion of the shell and the outer side of the rotating tube of the rotor and the fourth extension portion form a material reflux interlayer, and the material diffused by the centrifugal wheel to the upper side of the second extension portion can flow back to the bottom of the shell through the reflux interlayer;

[0014] By arranging the paddle pump blades at the bottom of the rotating tube, the paddle pump blades are closer to the circumferential recessed position at the bottom of the shell, thereby improving the pumping effect of the paddle pump blades on the materials. At the same time, a fourth extension portion extending obliquely upward is arranged on the upper side of the rotating tube, so that the fourth extension portion of the rotor and the second extension portion of the shell form an oil reflux port. The raw materials flowing on the shell can flow back through the oil reflux port into the oil-containing interlayer formed by the rotating tube and the boiling pot shell. The oil in the interlayer is then pumped downwardly by the spiral blades on the outer side of the rotating tube to flush the chili oil raw materials at the bottom of the shell.

[0015] Preferably, a spiral blade is also provided at the bottom of the outer side of the rotating tube, and the spiral blade is located at the bottom of the reflux interlayer. The rotation of the rotating shaft can drive the rotating tube to rotate, and then drive the spiral blade to rotate to spray the material flowing into the reflux interlayer downward, thereby flushing and stirring the inner side of the circular depression at the bottom of the shell. By arranging the spiral blade at the bottom of the outer side of the rotating tube, the spiral blade is closer to the circular depression at the bottom of the shell, thereby enhancing the flushing effect of the spiral blade on the oil in the circumferential interlayer pumped downward. In combination with the circular depression setting, the flushing effect of the oil pumped downward by the circumference is further improved (the oil pumped downward impacts the middle position of the bottom edge of the circular depression of the folded shell).

[0016] Preferably, a heater is provided on the lower side of the second extension portion. When the centrifugal wheel pushes the material to spread and flow on the upper side of the second extension portion, the heater heats the material on the upper side of the second extension portion. By providing the heater on the lower side of the second extension portion, when the rotor pumps the oil upward and the centrifugal wheel spreads the oil circumferentially above the second portion, the oil is heated. During this process, the oil is mixed with a certain amount of air introduced at the upper end of the pot bottom (a controlled amount of air is introduced through an air supply device to prevent excessive oxygen introduction from damaging the taste or causing dangerous situations). Then the oil is quickly heated and flows back to the bottom of the housing. This process utilizes the lubricating fluidity of the oil itself and efficiently simulates the process of stir-frying chili oil in a traditional catering store, and maintains a large production capacity. Furthermore, it strongly ensures the spicy aroma flavor of the chili oil in terms of production process means.

[0017] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0018] 1. Through the circumferential diffusion ability of the rotor of the boiling pot of the present invention and in cooperation with the design of the second extension portion of the boiling pot housing, the oil pumped out by the rotor rotating in the pot can be evenly diffused to the upper side of the second extension portion of the housing. During the process of the chili oil flowing back, it receives the heating function of the second extension portion, efficiently simulating the stir-frying process of a small pot. At the same time, the uniformity of its stir-frying is not weaker than that of a small pot stir-frying. It ensures the flavor of the chili oil in the process of boiling and stir-frying. At the same time, by spraying appropriate food-grade air through the circular ventilation notch provided at the top of the housing, it ensures the oxidation of the chili oil raw materials, thus ensuring the spicy aroma of the chili oil;

[0019] 2. By providing spiral blades on the outer side of the rotating pipe and providing a circular depression at the bottom of the housing of the boiling pot of the present invention, during the rotation of the spiral blades, the oil in the annular interlayer between the rotating pipe and the first extension portion is pumped into the circularly depressed housing. The oil pumped downward rushes into the circumferentially depressed position along the edge of the bottom of the housing and converges towards the middle along the edge of the circumferential depression. During this process, the oil gathers the chili oil raw materials to the middle position. At this time, the synchronously rotating paddle pump blades pump the oil in the middle upward and then flow back through the second extension portion of the housing, forming a circulating stir-frying process. This process fully and efficiently ensures the uniformity and sufficiency of the oil stir-frying in the pot, and ensures the quality of the chili oil in the boiling pot;

[0020] 3. The boiling pot in the present invention can still ensure sufficient spicy aroma of the stir-fried chili oil under different volumes (different stir-frying capacity designs). It has strong adaptability in large-scale industrial production, and thus also has good economic benefits;

[0021] 4. The present invention purifies and adsorbs the oil fume discharged by the present invention by setting an oil fume purifier to prevent the oil fume from being discharged to the outside. In this process, the oil fume adsorbed by the oil fume purifier reduces the carbonized matter in the atmosphere, reduces the carbon emission of the present invention, and increases the environmental protection ability of the present invention. It is stronger than the traditional chili oil extraction device. Under the current high demand for energy conservation and emission reduction, the present invention has better adaptability than the traditional chili oil extraction device.

[0032] To make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in combination with embodiments and drawings. The illustrative implementation modes and descriptions of the present invention are only used to explain the present invention and shall not be construed as a limitation to the present invention.

[0033] Embodiment:

[0034] As Figures 1 to 8 shown, this embodiment includes a boiling pot 1, an air supplier, an oil residue filter, and an oil storage tank for finished chili oil. In this embodiment, the air supplier includes a food-grade air compressor 2 and a fume purifier 6. Among them, the food-grade air compressor 2 is connected to the boiling pot 1 through the air inlet pipe 1017, and the fume purifier 6 is connected to the boiling pot 1 through the exhaust pipe 1018. The air inlet pipe 1017 is provided with a second valve 201. The air compressed and stored by the food-grade air compressor 2 enters the boiling pot 1 after passing through the second valve 201. In this process, the microcontroller controls the amount of air introduced by the opening and closing degree of the valve. After air is introduced into the boiling pot 1, the internal air pressure rises. An exhaust pipe 1018 is provided at the middle position of the boiling pot 1 to discharge the internal gas to maintain the air pressure inside the frying process. The gas discharged from the exhaust pipe is then purified by the fume purifier 6 and then discharged into the atmosphere. It is worth mentioning that both the air compressor and the fume purifier 6 are conventional technical means, and only briefly mentioned in this embodiment without further elaboration;

[0035] A pipeline is connected to the bottom of the boiling pot 1. A first valve 101 is provided at the front end of the pipeline and the first valve 101 is located at the bottom of the boiling pot 1. A first oil pump 3 is provided at the middle position of the pipeline. After the boiling pot 1 has fried chili oil, the first valve 101 at the bottom of the boiling pot 1 is controlled by the microcontroller to allow the oil in the boiling pot 1 to enter the pipeline. At this time, the first oil pump 3 is started, and the fried oil is pumped into the oil residue filter through the first oil pump 3. The oil residue filter in the embodiment uses a filter press 4. The filter press 4 filters and presses and separates the oil mixed with the oil pumped by the first oil pump 3, separating the chili oil and raw materials in the oil. A pipeline is connected to the chili oil outlet of the filter press 4. A second oil pump 7 is provided at the middle position of the pipeline. When the filter press 4 is working, the second oil pump 7 is started to pump the chili oil separated by the filter press 4 into the storage oil tank. The storage unit in the embodiment uses a storage oil tank 5. A pipeline is connected to the bottom of the storage oil tank 5. A third valve 501 is provided on the pipeline. The operator can control the external extraction of chili oil by controlling the opening and closing of the third valve 501. It is worth mentioning that the filter press 4 including the first oil pump 3 and the second oil pump 7 and the storage oil tank 5 also belong to the conventional technical means in this technical field. The embodiment drawings only briefly show them. As a conventional technical device, it is not within the scope of the distinguishing features of this embodiment, and the embodiment will not be described in detail.

[0036] The boiling pot 1 of the embodiment includes a housing 103, a rotor 104, and a driving unit that provides driving force for the rotor 104. In this embodiment, the driving unit uses a motor 1019. The rotor 104 is disposed inside the housing 103 of the boiling pot 1. The rotor 104 includes a rotating shaft 109, and the rotating shaft 109 is vertically downward. The upper part of the rotating shaft 109 passes through the housing cover 1014 at the upper part of the housing 103 and is connected to the shaft of the motor 1019. The rotation of the shaft of the motor 1019 drives the rotation of the rotating shaft 109. An insulating disc 1020 is also provided between the housing cover 1014 and the motor 1019. The insulating disc 1020 can prevent the high temperature inside the boiling pot 1 from being transmitted to the motor 1019, thereby maintaining the normal operation of the motor 1019 (when the motor 1019 exceeds 70 degrees Celsius, the insulating paint of the armature enameled wire of the motor will quickly melt, causing a serious short-circuit accident in the motor armature, resulting in a failure and stopping operation). A paddle pump blade 107 is fixed to the lower end of the rotating shaft 109. A rotating pipe 106 is also sleeved on the circumferential outer side of the paddle pump blade 107. The rotation of the rotating shaft 109 can drive the rotation of the paddle pump blade 107. The paddle pump blade 107 and the rotating pipe 106 can pump the oil at the bottom 1011 of the housing of the boiling pot 1 upward. A fourth extension portion 1024 is formed by tilting and extending upward along the upper edge of the rotating pipe 106. The fourth extension portion 1024 is in the shape of a funnel cone. At the same time, a centrifugal wheel 108 is fixed above the paddle pump blade 107 and on the rotating shaft 109. The lower end of the centrifugal wheel 108 is connected to the inner side of the fourth extension portion 1024 of the rotating pipe 106. When the rotating shaft 109 of the rotor 104 rotates, the paddle pump blade 107 and the rotating pipe 106 pump the oil at the bottom 1011 of the housing upward. The oil pumped upward is simultaneously centrifugally diffused around by the action of the centrifugal wheel 108 above the paddle pump blade 107;

[0037] The bottom of the boiling pot 1 is a circularly sunken housing bottom 1011. The upper edge of the housing bottom 1011 extends upward to form a first extension part 1012. An oil return sandwich layer 1022 is formed between the first extension part 1012 and the rotating pipe 106. In the oil return sandwich layer 1022 of the oil, a spiral piece 105 is fixed outside the rotating pipe 106. When the rotating shaft 109 rotates, the oil in the return sandwich layer 1022 outside the rotating pipe 106 will be pumped downward under the action of the spiral piece 105. And because both the return sandwich layer 1022 and the matching spiral piece 105 are annular and located at the edge of the housing 103, the oil pumped downward in the return sandwich layer 1022 impacts downward along the circumference of the housing 103. The downward-impacting oil cleverly impacts the chili oil raw materials inside the oil deposited at the housing bottom 1011 toward the middle of the housing bottom 1011. The chili oil raw materials gathering toward the middle are pumped upward under the upward pumping action of the paddle pump blade 107. Immediately above the upper edge of the first extension part 1012, a second extension part 1013 extends obliquely upward. The second extension part 1013 forms a large conical funnel-like shape, and a heater 102 is also provided at the lower end of the second extension part 1013. When the rotor 104 rotates, the oil diffusing circumferentially in all directions under the action of the rotor 104 will surge onto the upper side of the second extension part 1013 and quickly flow back to the middle and into the return sandwich layer 1022. During this process, the oil on the upper side of the second extension part 1013 will be heated by the second extension part 1013. This process well simulates the process of stir-frying chili oil in a small pot in a traditional small restaurant. Additionally, above the upper edge of the second extension part 1013, a third extension part 1023 continues to extend vertically upward. A circular housing cover 1014 is fixed to the upper edge of the third extension part 1023. An annular ventilation pipe 1015 is laid and fixed on the circular housing cover 1014. The annular ventilation pipe 1015 is concentric with the circular housing cover 1014. An annular ventilation gap 1021 is provided at the annular connection part of the annular ventilation pipe 1015 and the housing cover 1014. The annular ventilation pipe 1015 is communicated with the inside of the housing 103 through the annular ventilation gap 1021. At the same time, the air inlet pipe 1017 of the housing 103 is communicated with the annular ventilation pipe 1015. When air is introduced into the annular ventilation pipe 1015 through the air inlet pipe 1017, the air will quickly expand to form an annular air chamber inside the annular ventilation pipe 1015. The annular air chamber then enters the housing 103 through the annular ventilation gap 1021. When the rotor 104 rotates, the oil diffusing circumferentially in all directions in the housing 103 will be fully mixed with the annular air flow introduced through the annular ventilation gap 1021, ensuring that a certain degree of oxidation can occur when the oil falls on the second extension part 1013 for heating, and ensuring that the oil produces enough pungent aroma. It is worth mentioning that in the traditional chili oil boiling pot 1, in order to prevent the chili oil raw materials from precipitating or sticking to the bottom of the pot during boiling, the stirring device often adds a steel brush to the bottom of the stirring rotor 104.The chili oil raw materials deposited at the bottom of the pot are repeatedly brushed up by a steel brush. However, as a pot-like utensil, the housing 103 is often relatively thin. Under the repeated brushing of the steel brush at the bottom of the pot, the service life of the bottom of the pot will be greatly reduced. At the same time, in order to prevent the oil from flowing back too quickly at the second extension part 1013, the embodiment controls the angle between the extension edge of the second extension part 1013 and the horizontal line to be between 10 degrees and 25 degrees (specifically, it also needs to be determined according to the specific specifications of the boiling pot 1), so as to provide a suitable heating time for the raw materials flowing above the second extension part 1013.,

[0038] The specific embodiments described above have further elaborated on the purpose, technical solutions, and beneficial effects of the present invention. It should be understood that the above are only specific embodiments of the present invention and are not used to limit the protection scope of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.,
