Description

Technical Field

[0001] This utility model relates to the field of food processing technology, specifically to a stir-frying device with an adjustable stirring position. Background Technology

[0002] In the food industry, stir-fry equipment with electric stirrers is widely used in the factory production of condiments and some dishes. Whether it's liquid condiments like soy sauce and vinegar, or semi-solid ingredients like sauces and batters, stirring is a crucial step in ensuring consistent product quality and taste. However, traditional self-stirring equipment typically uses stirring blades of fixed height. For example, patents such as CN218485751U (a stirring device for condiment production), CN208809987U (a raw material mixing and melting device for butter and ghee production), CN205803423U (an oil steaming and stir-frying device), CN117598464A (a Tibetan medicine hot pot base formula, processing equipment, and processing technology), and CN221656368U (a seasoning oil mixing and blending device) all share a common feature with actual stir-fry equipment with stirring functions: the height of the stirring blades is not adjustable. This presents numerous limitations in practical applications.

[0003] First, different mixing tasks require different insertion depths for the mixing blades. For example, heavier raw materials require deeper insertion depths to ensure thorough mixing, while lighter or viscous materials may require shallower insertion depths to avoid excessive agitation and the formation of too many air bubbles.

[0004] Secondly, considering mixing efficiency and uniformity: to mix materials more quickly and evenly, the insertion depth of the mixing blades must be adjusted according to specific circumstances. Inserting too deeply or too shallowly will affect the mixing effect, leading to uneven mixing in a short time or requiring a longer time to achieve uniform mixing, resulting in low efficiency.

[0005] Third, considering adaptability to various application scenarios: In production, the same stir-frying equipment may be used to process different types and weights of materials. Therefore, stir-frying equipment that can flexibly adjust the insertion depth of the stirring blades is particularly important, as it can significantly improve the versatility and efficiency of the equipment. Utility Model Content

[0006] The present invention aims to provide a stir-frying device with an adjustable stirring position to solve the problem that the height of the stirring blades in current food processing stir-frying devices is not adjustable.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] An adjustable stirring device includes a pot body, a stirrer, and a heater. The heater is used to heat the pot body, and the stirrer is used to insert into the pot body for stirring. The stirrer includes a drive motor, a stirring shaft, and stirring blades. The drive motor is fixedly installed, and the stirring shaft includes a first section and a second section. The first section is fixedly connected to the output end of the drive motor, and the stirring blades are installed on the second section. The first section and the second section are sleeved together, and the second section can move axially relative to the first section. The device also includes a locking member for locking the relative position of the first section and the second section.

[0009] The principle and advantages of this solution are as follows: When it is necessary to adjust the height of the stirring blades according to different stirring tasks, the locking parts can be released from the first and second sections first. After the relative positions of the first and second sections are adjusted, the length of the stirring shaft can be adjusted, which means that the height of the stirring blades in the pot can be changed to adapt to the stirring requirements of different height requirements of the stir-frying device.

[0010] Preferably, as an improvement, a guide post is fixed at the bottom of the inner cavity of the pot body, and the second end of the stirring shaft is rotatably connected to the guide post. This solution ensures the rotational stability of the stirrer during stirring by setting a guide post in the pot body, so that both ends of the stirring shaft are limited in rotation.

[0011] Preferably, as an improvement, one of the second section and the guide post has a protrusion and the other has a groove. The protrusion can be inserted into the groove, and there can be a gap between the top of the protrusion and the groove. This solution facilitates the adjustment of the stirring shaft length, and the stirring shaft is also guided by the guide post when it extends into the bottom of the pot, ensuring the stability of the stirring shaft rotation process.

[0012] Preferably, as an improvement, the pot also includes a lid, which is detachably attached to the pot body, and the motor of the stirrer is fixed to the lid.

[0013] Preferably, as an improvement, the pot lid is dome-shaped, the drive motor is installed at the top of the pot lid, the curved side of the pot lid is provided with a feeding port, and a door is installed on the feeding port that can block or open the feeding port; a discharge port is opened at the bottom of the pot body, and the discharge port is blocked or opened by any one of a plug / partition / discharge valve.

[0014] Beneficial effects: By setting the pot lid in a dome shape, the enclosed space between the pot lid and the pot body is larger, which makes it easier to set a larger feeding port for feeding. At the same time, it also allows the drive motor to be installed at a position far away from the pot body. In addition, the discharge port at the bottom of the pot body makes it convenient to quickly discharge the material in the pot body directly through the discharge port after the stir-frying is completed.

[0015] Preferably, as an improvement, the pot lid is also equipped with at least two oil spray nozzles, with the nozzle heads facing the inner cavity of the pot. All the oil spray nozzles are evenly distributed around the stirrer, so that the raw materials sprayed by the oil spray nozzles are more evenly distributed in the pot.

[0016] Preferably, as an improvement, the pot lid is also equipped with a smoke exhaust pipe to facilitate the timely removal of oil fumes generated during the stir-frying process.

[0017] Preferably, as an improvement, the exhaust pipe is a flexible hose or a telescopic pipe with an adjustable bending path. The exhaust pipe is connected to the fume extraction device, and an oil fume sensor is installed inside the exhaust pipe. Both the oil fume sensor and the fume extraction device are connected to a controller. The controller is used to start the fume extraction device after the oil fume concentration collected by the oil fume sensor reaches a set value. This eliminates the need for the fume extraction device to run continuously during cooking, but only needs to start when oil fumes are generated and reach the set concentration. This avoids unnecessary energy consumption of the fume extraction device and contributes to energy conservation and environmental protection.

[0018] Preferably, as an improvement, the pot body has a jacket containing heat transfer oil. The jacket is connected to an oil inlet and an oil outlet. The oil inlet is used to inject heat transfer oil, and the oil outlet is used to discharge heat transfer oil. A circulation pump is connected between the oil inlet and the oil outlet. The oil outlet is connected to the feed end of the circulation pump through a pipe. A cooler is installed on the pipe between the oil outlet and the feed end.

[0019] Beneficial Effects: When using this solution, the heat transfer oil itself conducts heat, ensuring a consistent temperature on the inner wall of the pot during heating, thus guaranteeing uniform heating of the materials inside. When the temperature needs to be lowered to the set temperature after heating, the circulation pump is activated, allowing the hot heat transfer oil to enter the cooler for cooling. The cooled oil is then pumped back into the jacket through the inlet, continuously circulating and exchanging heat. This facilitates rapid cooling of the pot without transferring the materials. Compared to existing technologies, this solution does not rely on natural cooling, thus significantly increasing the cooling rate. Because the jacket serves both as a heat transfer and cooling layer, there is no need to transfer the materials inside the pot, saving labor costs associated with material transfer while maintaining a high cooling rate.

[0020] Preferably, as an improvement, the cooler includes a cooling box containing a cooling liquid, and a pipe connecting the oil outlet and the feed end of the circulating pump passes through the cooling liquid, so as to achieve cooling through a simple cooling structure.

[0021] Preferably, as an improvement, the cooling box is equipped with a spiral pipe, one end of which is connected to the oil drain port, and the other end of which is connected to the feed end of the circulation pump. This design allows the heat transfer oil to play a heat-conducting role when the raw materials are stirred in the heated state of the pot, ensuring a uniform temperature of the inner wall of the pot. When the stirring is completed and the materials in the pot need to be cooled, the circulation pump is started, so that the heat transfer oil continuously circulates and flows through the spiral pipe where the cooling liquid is located. The spiral pipe greatly extends the time that the heat transfer oil is surrounded by the cooling liquid, thereby continuously exchanging the heat in the raw materials and realizing rapid cooling of the raw materials in the pot.

[0032] The following detailed description illustrates the specific implementation method:

[0033] The reference numerals in the accompanying drawings include: pot body 10, jacket 101, oil inlet 102, oil outlet 103, temperature sensor 104, plug 105, guide column 106, pot lid 20, feed port 201, sliding door 202, oil injector 203, exhaust pipe 204, stirrer 30, stirring shaft 1, first section 11, second section 12, contact surface 121, groove 122, locking element 13, stirring blade 2, drive motor 3, upper stirring blade 21, lower stirring blade 22, combustion heater 40, circulation pump 50, cooler 60, cooling box 61, spiral pipe 62, guide body 70, and combustion chamber 701.

[0034] Example 1

[0035] Combination Figures 1 to 3 A stir-frying device with adjustable stirring position includes a pot body 10, a pot lid 20, a stirrer 30, and a combustion heater 40. The pot body 10 has a circular cross-section and is fixedly supported by a fixed bracket (not shown in the figure). The pot body 10 has a jacket 101, which is a cavity used to contain heat transfer oil. The top of the cavity is connected to an oil inlet 102 and an oil outlet 103, which are located on both sides of the pot body 10. The oil inlet 102 is used to inject heat transfer oil, and the oil outlet 103 is used to discharge heat transfer oil. A circulation pump 50 is connected between the oil inlet 102 and the oil outlet 103. The oil outlet 103 is connected to the feed end of the circulation pump 50 through a pipe. A cooler 60 is installed on the pipe between the oil outlet 103 and the feed end.

[0036] Specifically, the cooler 60 includes a cooling box 61 containing cooling liquid. A spiral pipe 62 is installed inside the cooling box 61. One end of the spiral pipe 62 is connected to the oil drain port 103, and the other end is connected to the feed end of the circulation pump 50. This allows the heat-conducting oil to conduct heat during the stirring of the raw materials inside the pot 10 while it is heated, ensuring a uniform temperature on the inner wall of the pot 10. When the stirring is complete and the material inside the pot 10 needs to be cooled, the circulation pump 50 is activated, causing the heat-conducting oil to continuously circulate and flow through the spiral pipe 62 containing the cooling liquid. The spiral pipe 62 significantly extends the time the heat-conducting oil spends within the cooling liquid, thereby continuously removing heat from the raw materials and achieving rapid cooling of the raw materials inside the pot 10.

[0037] In actual use, when the pot body 10 is heated, the heat transfer oil in the jacket 101 will be vaporized. In order to avoid excessive pressure in the jacket, a U-shaped bend (i.e., the heat transfer oil pipeline in the disclosed technology) as shown in patent publication number CN102949086B can be connected to the oil inlet 102 or the oil outlet 103. The top of the U-shaped bend is higher than the jacket 101, and a blower is connected to the other end of the U-shaped bend. The blower is used to send the vaporized heat transfer oil into the combustion heater 40 for combustion.

[0038] A temperature sensor 104 is installed inside the pot body 10 to detect the temperature of the raw materials inside the pot. Both the temperature sensor 104 and the circulation pump 50 are connected to a controller. The controller starts the circulation pump 50 upon receiving a cooling command and stops the circulation pump 50 once the temperature sensor 104 detects that the set temperature has been reached. An alarm connected to the controller is also included, which sounds an alarm when the temperature inside the pot body 10 reaches the set temperature after cooling, thereby improving the level of automation.

[0039] The bottom of the pot body 10 is provided with a discharge port for discharging materials inside the pot body 10. In this embodiment, during the stirring process, other parts such as a plug 105, a baffle, or a discharge valve are installed on the discharge port to seal it, preventing the raw materials from being discharged directly. After stirring is completed, the discharge port is opened to facilitate the timely, quick, and simple discharge of the stirred raw materials. This embodiment uses the plug 105 as an example.

[0040] The lid 20 is detachably connected to the pot body 10. The top of the pot body 10 is open. The lid 20 has a dome-shaped structure and covers the top opening of the pot body 10. The lid 20 has a feeding port 201, which is a large opening on the side of the curved lid 20. A curved sliding door 202 is installed on the large opening. The sliding door 202 is slidably connected to the lid 20. When the sliding door 202 slides, it rotates around the center of the lid 20. Specifically, the surface of the pot lid 20 is provided with an annular groove, and at least two sliding posts are installed on the sliding door. These posts are slidably connected within the annular groove. The sliding posts are cylindrical and inserted into the annular groove, allowing the sliding door 202 to move along the groove to cover the feeding port 201 and adjust its opening size, thus facilitating the addition of materials. The combination of the sliding door 202 and the curved shape of the pot lid 20 allows for a larger feeding port 201, facilitating the addition of materials into the pot body 10 and enabling the port to be closed after material addition, thus contributing to the increase in temperature within the pot body 10. The sliding door 202 can be transparent, allowing for easy observation of the cooking process. The main body of the pot lid 20 is made of a high-temperature resistant metal material, such as stainless steel, to ensure sufficient strength.

[0041] The lid 20 is also equipped with multiple oil spray nozzles 203, which are evenly distributed around the stirrer 30. Each oil spray nozzle 203 sprays oil into the pot body 10 so that the oil can be more evenly distributed in the ingredients when stir-frying.

[0042] In addition, a smoke exhaust pipe 204 is connected to the pot lid 20 in this embodiment. The smoke exhaust pipe 204 is used to connect to a fume extraction device so that if there is oil smoke during the stirring process, it can be discharged quickly and promptly through the smoke exhaust pipe 204.

[0043] Combination Figure 1 , Figures 4 to 10 The agitator 30 includes a drive motor 3, a stirring shaft 1, and stirring blades 2. The drive motor 3 is used to drive the stirring shaft 1 to rotate. The drive motor 3 is fixed on the top of the pot cover 20. The stirring blades 2 are fixed on the stirring shaft 1. The stirring blades 2 penetrate into the pot body 10 to stir the material, so that the material in the pot body 10 is stirred evenly. At the same time, it also helps to increase the cooling rate by stirring during the cooling process.

[0044] The length of the stirring shaft 1 can be adjusted.

[0045] Specifically, the stirring shaft 1 includes a first section 11 and a second section 12. The first section 11 is fixedly connected to the output end of the drive motor 3. The drive motor 3 is fixedly installed on the stirring device and is used to drive the stirring shaft 1 to rotate.

[0046] The stirring blade 2 is fixed on the second section 12 away from the drive motor 3. The first section 11 is sleeved with the second section 12, and the second section 12 can move axially relative to the first section 11. It also includes a locking member 13 for locking the relative position of the first section 11 and the second section 12.

[0047] Combination Figures 4 to 7 In one embodiment, the adjustable length of the stirring shaft 1 is specifically achieved as follows: the first section 11 facing the second section 12 is machined into a sleeve, the top of the second section 12 is machined into a shaft section, the shaft section is sleeved with the sleeve, and a locking member 13, which is a locking pin, is threaded onto the sleeve. The locking pin is inserted into the sleeve and abuts against the shaft section of the second section 12. To improve the locking force of the locking pin on the shaft section, at least one abutment surface 121 is provided on the shaft section. The shaft section can be... Figure 5 The cylindrical shaft shown has an axial abutment groove, which can also be... Figure 6The shaft segment is a polygonal structure (a regular hexagonal structure in the figure), and the sleeve and the polygonal cross section of the shaft segment are fitted together. When adjusting the length of the stirring shaft 1, the locking pin is turned to release the locking pin from the second segment 12. Then, the second segment 12 is controlled to slide axially relative to the first segment 11, thereby adjusting the overall length of the stirring shaft 1. After the length adjustment is completed, the locking pin is turned again to make the locking pin press against the inner wall of the sleeve of the second segment 12 and the first segment 11, thereby ensuring that the length of the stirring shaft 1 will not change easily.

[0048] Combination Figure 8 and Figure 9 In another embodiment, the length of the stirring shaft 1 is adjustable as follows: the first section 11 and the second section 12 are connected by threads. The sleeve of the first section 11 is provided with internal threads, and the shaft section of the second section 12 is provided with external threads. The locking member 13 is a locking nut, which is threaded onto the external threads. After the relative positions of the first section 11 and the second section 12 are adjusted, the length of the first section 11 and the second section 12 is locked by using the locking nut to press against the bottom end face of the first section 11. When adjusting the length, the locking nut is first turned away from the first section 11, and then the second section 12 is turned so that the axial position of the second section 12 relative to the first section 11 changes. After the adjustment is completed, the locking nut is turned again to press against the bottom end face of the first section 11, thereby completing the locking of the length of the stirring shaft 1. In this embodiment, the height position of the stirring blade 2 relative to the pot body 10 is adjusted by adjusting the length of the stirring shaft 1. After the height is adjusted, the distance between the stirring blade 2 and the inner wall of the pot body 10 is adjusted, thereby adapting to different stir-frying needs.

[0049] The stirring blade 2 includes an upper stirring blade 21 and a lower stirring blade 22 located at different heights. The distance between the upper stirring blade 21 and the inner wall of the pot body 10 is greater than the distance between the lower stirring blade 22 and the inner wall of the pot body 10. In a specific embodiment, the distance between the lower stirring blade 22 and the inner wall of the pot body 10 can be set to be no less than 1 mm. The distance between the upper stirring blade 21 and the inner wall of the pot body 10 is no less than 5 mm.

[0050] There are multiple lower stirring blades 22, which are evenly distributed around the stirring shaft 1. Each lower stirring blade 22 is arc-shaped, and the arc shape of the lower stirring blade 22 makes the distance between the lower stirring blade 22 and the inner wall of the pot body 10 gradually change, reducing the difficulty of stirring when the lower stirring blade 22 is used.

[0051] There are multiple upper stirring blades 21, and these blades are evenly distributed around the stirring shaft 1. The upper stirring blades 21 are inclined plates.

[0052] Combination Figure 1 and Figure 10In one embodiment, a guide post 106 is fixedly installed at the bottom of the pot body 10. The guide post 106 is coaxial with the stirring shaft 1 and is cylindrical. The cylindrical guide post 106 is equivalent to forming a circular protrusion. A groove 122 is machined at the bottom of the second section 12. The protrusion is inserted into the groove 122. There is a gap between the protrusion and the groove 122 so that even if the length of the stirring shaft 1 is adjusted, the bottom of the stirring shaft 1 is still limited by the guide post 106, ensuring that both ends are limited when the stirring shaft 1 rotates, thus ensuring the rotational stability of the stirring shaft 1.

[0053] In this embodiment, the adjustable length of the stirring shaft 1 is used to adapt to the stirring requirements of different stirring tasks, and the upper stirring blade 21 and the lower stirring blade 22 are set to make the stirring efficiency high and the stirring more uniform.

[0054] The combustion heater 40 is located below the pot body 10 and also includes a guide body 70 to prevent rapid heat loss. The pot body 10 has an arc-shaped structure. The guide body 70 surrounds the pot body 10 from the bottom. A combustion chamber 701 is formed between the guide body 70 and the bottom of the pot body 10. The combustion chamber 701 surrounds the jacket 101. An installation cavity is connected in the middle of the combustion chamber 701. The combustion heater 40 is installed in the installation cavity. The flame and heat generated by the combustion heater 40 are directed toward the combustion chamber 701 so that the heat generated by the combustion heater 40 can quickly heat up the heat transfer oil in the jacket 101.

[0055] Example 2

[0056] Example 2 is an improvement on Example 1. Specifically, an oil fume sensor (not shown in the figure) is installed inside the exhaust pipe 204. The oil fume sensor and the oil fume extraction equipment are both connected to the controller. The controller is used to start the oil fume extraction equipment after the oil fume concentration collected by the oil fume sensor reaches the set value. This way, the oil fume extraction equipment does not need to be continuously started during the cooking process, but only needs to be started after oil fumes are generated and reach the set concentration. This avoids the useless energy consumption of the oil fume extraction equipment and helps to save energy and protect the environment.

[0057] The controller also allows for different levels of fume concentration settings for starting the fume extraction equipment. Different levels of fume concentration correspond to different extraction speeds when the fume extraction equipment starts. The higher the fume concentration in the exhaust pipe 204, the faster the extraction speed. This further improves the intelligent control of fume extraction, taking into account energy conservation and environmental protection, while ensuring that the extraction speed is automatically adjusted in a timely and rapid manner when the fume concentration is high, so that the fume can be discharged quickly and in a timely manner regardless of its size.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solution of this utility model. These modifications and improvements should also be considered within the scope of protection of this utility model, and will not affect the effectiveness of the implementation of this utility model or the practicality of the patent.
