Description

Technical Field

[0001] The invention relates to the technical field of food flavors, and in particular to a method and equipment for preparing a hot-reaction flavor of broad bean paste. Background Art

[0002] Doubanjiang flavor is a non-animal food additive prepared through thermal reaction technology. It makes full use of the unique aroma and flavor produced by traditional Doubanjiang fermentation and is widely used in condiments, meat products, and snack foods. Doubanjiang flavor is often prepared in high-temperature and high-pressure reactors.

[0003] The high-temperature and high-pressure reactor used for the preparation of bean paste flavor is mainly composed of a high-temperature and high-pressure reactor, a heater, a cooling device, a stirring blade and a motor. The high-temperature and high-pressure reactor is provided with a feed port and a discharge port for the entry of raw materials and the discharge of reaction products. The high-temperature and high-pressure reactor is provided with a heater and a cooling device for controlling the temperature inside the high-temperature and high-pressure reactor. The stirring blade is rotatably installed on the central axis of the high-temperature and high-pressure reactor. The stirring blade is fixedly installed with the motor, and the motor is fixedly installed on the high-temperature and high-pressure reactor. During production, the raw materials are added to the high-temperature and high-pressure reactor, and then the temperature inside the high-temperature and high-pressure reactor is increased by the heater. At the same time, the motor is started to control the rotation of the stirring blade to mix the raw materials. When the reaction is completed, the cooling device cools down the high-temperature and high-pressure reactor, and the cooled reactants are discharged from the high-temperature and high-pressure reactor.

[0004] However, when the stirring blade stirs the raw materials, the shear force of the stirring blade on the raw materials is insufficient due to the high viscosity of the raw materials, which leads to uneven mixing and causes the raw materials at the bottom of the high-temperature and high-pressure reactor to coke. At the same time, during the rotation of the stirring blade, the central axis area of ​​the stirring blade is difficult to generate sufficient shear force, causing the raw materials in the center to be stirred, resulting in uneven mixing in the center area.

[0005] In view of this, we propose a method and equipment for preparing hot-reaction flavor of broad bean paste. Summary of the Invention

[0006] The purpose of the present invention is to provide a method and equipment for preparing hot-reaction flavor of broad bean paste, so as to solve the problem of uneven mixing of raw materials leading to coking of raw materials and insufficient reaction proposed in the above background technology.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a method and equipment for preparing hot-reaction flavor of broad bean paste: A method for preparing a hot-reaction flavor of broad bean paste comprises the following steps: Step 1: Mix the fermented black beans, fermented black beans and purified water and grind them; Mix the fermented black beans and pure water, and grind them into a particle size of ≤5 μm using a colloid mill; Step 2: Mix onion, garlic and purified water and beat into a paste; Evenly mix the purple onion puree, garlic puree and purified water, then filter to make slurry; Step 3: Add the pretreated raw materials, mud and other auxiliary materials into a high temperature and high pressure reactor for reaction; The pretreated raw materials, slurry and other auxiliary materials were added to a high-temperature and high-pressure reactor and reacted at 120°C and 0.3 MPa for 1 hour; Step 4: Cool the reaction product to 70-60°C, homogenize and then fill; After the prepared hot-reaction flavor of the bean paste is cooled, it is placed in a homogenizer for refinement and uniform dispersion, and then filled to complete the production.

[0008] Preferably, the auxiliary materials include complex amino acids, reducing sugars, nitrogen sources and spices.

[0009] Through the synergistic effect of complex amino acids and reducing sugars, combined with high temperature and high pressure reaction, the layering and persistence of sauce aroma are significantly enhanced; Improve the heat resistance and storage stability of flavors through nitrogen sources; Improve the flavor and palatability of the heat-reactive flavor of bean paste by using spices; Preferably, the composite amino acid is a mixture of cysteine ​​hydrochloride, alanine and glycine; Cysteine ​​hydrochloride is a sulfur-containing amino acid that can generate compounds with meaty aromas in the Maillard reaction. For example, heating cysteine ​​hydrochloride with glucose, ribose, and other sugars can produce compounds with a beefy aroma. Furthermore, cysteine ​​hydrochloride works synergistically with other amino acids, such as glycine, to further enhance the complexity and smoothness of flavors. Alanine has a certain umami flavor that can enhance the umami taste of food. Alanine can produce a variety of flavor compounds in the Maillard reaction. For example, when alanine reacts with reducing sugars such as glucose, it produces fruity, floral, and sweet aromas. In addition, the Maillard reaction involving alanine can also produce volatile aroma compounds such as pyrazines and furans, which can significantly enhance the flavor complexity of food. Glycine itself has a sweet taste and is used as a flavoring agent. Glycine can synergize with other ingredients, such as reducing sugars and cysteine, in Maillard reactions to generate a variety of flavor compounds. For example, in a glucose-cysteine system, the addition of glycine can significantly improve the meaty and roasted flavors of the system. After glycine participates in the reaction, a variety of volatile and non-volatile flavor compounds are generated. For example, in Maillard reactions, glycine reacts with glucose to produce caramel aroma. In addition, the addition of glycine can affect the concentration of specific flavor compounds, such as 1,2-ethanedithiol and 2,4,5-trimethylthiazole. Preferably, the nitrogen source is yeast extract and acid hydrolyzed plant protein powder; The ratio of yeast extract to acid hydrolyzed plant protein powder is 1:2; The main components of yeast extract are proteins, amino acids, polypeptides, nucleotides, vitamins, and trace elements, which are rich in nutrients and of high quality. They can improve food flavor, enhance flavor, reduce salt and saltiness, balance off-flavors, and the like. Hydrolyzed plant protein can provide a better source of amino acids, which is easier for the human body to absorb and utilize, providing the body with the required protein nutrition. At the same time, hydrolyzed plant protein also has certain functionality, which can extend the shelf life of food and improve the stability of food.

[0010] A device for preparing hot-reaction flavor of broad bean paste comprises a high-temperature and high-pressure reactor, a stirring shaft, stirring blades, a rotating assembly, a reciprocating assembly and a flipping rod; the high-temperature and high-pressure reactor is provided with a motor, and a feed port and a discharge port are provided on the high-temperature and high-pressure reactor. The feed port is used to pass raw materials into the high-temperature and high-pressure reactor for reaction, and the discharge port is used to discharge the materials after the reaction. The motor is fixedly installed with the stirring shaft; the stirring shaft is located in the high-temperature and high-pressure reactor and is coaxially installed with the high-temperature and high-pressure reactor; the stirring shaft is provided with stirring blades in a linear array, and a shaft sleeve is provided between the stirring blades and the stirring shaft. The stirring shaft is provided with a driving chamber, and a rotating assembly is provided in the driving chamber, and the rotating assembly is connected to the stirring blade. When the stirring shaft rotates, the stirring shaft drives the stirring blade to rotate synchronously, and the rotating assembly drives the stirring blade to rotate on its own, and the rotating assembly drives the stirring blade to rotate on its own, thereby causing the stirring blade to rotate in the vertical direction, thereby causing the stirring The blades transport the raw materials at the bottom upward, realizing the circulation of the raw materials in the vertical direction. The stirring blades rotate horizontally with the stirring shaft to realize multi-angle mixing and stirring, avoiding the occurrence of uneven mixing. At the same time, the stirring effect is enhanced, the raw materials become loose, which is convenient for temperature transfer, and avoids local accumulation of raw materials leading to temperature increase and coking of raw materials, which affects the quality of the final product. The stirring blade is provided with a reciprocating component, and a turning rod is provided on the inner side of the reciprocating component. The turning rod is slidably mounted on the stirring shaft. When the stirring blade rotates, the rotating component drives the turning rod to slide back and forth along the central axis of the stirring shaft through the reciprocating component. When the stirring blade stirs the material, the shear force generated by the rotation in the circumference of the stirring shaft is small, thereby causing the raw materials near the stirring shaft to be not fully stirred and mixed. At this time, the reciprocating component drives the turning rod to fully turn the raw materials in the stirring shaft area, thereby evenly distributing the raw materials in the high-temperature and high-pressure reactor. At the same time, the internal gas is more easily distributed among the raw materials, thereby ensuring sufficient oxygen required for the thermal reaction, thereby improving the preparation efficiency and preparation quality.

[0011] Preferably, the rotating assembly includes a T-shaped rod, a fixed wheel, a driven wheel, a dredging rod, a reciprocating spring and a cam; the T-shaped rod is divided into a horizontal section and a vertical section, the horizontal section is a streamlined structure, the horizontal section is fixedly installed with the high-temperature and high-pressure reactor, the horizontal section of the T-shaped rod is fixedly installed with the high-temperature and high-pressure reactor, thereby ensuring the stability of the T-shaped rod as a whole, so that the T-shaped rod does not move, the streamlined structure of the horizontal section is used to reduce the resistance between itself and the raw material, thereby avoiding itself from affecting the stirring of the raw material, the vertical section is located in the driving chamber, and a linear array of fixed wheels is arranged on the vertical section; the number of the fixed wheels corresponds to the number of the stirring blades, and the fixed wheels are symmetrically arranged on both sides The driven wheel is rotatably connected to the inner wall of the driving chamber, and the driven wheel is fixedly connected to the stirring blade. The driven wheel is fixedly connected to the stirring blade. When the stirring blade follows the stirring shaft to rotate in the horizontal direction, the stirring blade drives the driven shaft to rotate horizontally synchronously. The driven wheel meshes with the fixed wheel during the rotation process, thereby realizing its own rotation, thereby driving the stirring blade to rotate synchronously, realizing the self-rotation of the stirring blade. When the stirring blade rotates, centrifugal force is generated, thereby throwing off the raw materials adhered to the stirring blade, reducing the adhesion of the raw materials to the stirring blade; the diameter of the driven wheel below the driving chamber is smaller than the diameter of the driven wheel above the driving chamber, When the mixing blades rotate and stir in the vertical direction, the raw materials below are subjected to greater pressure, so the force required to turn the raw materials below is greater than the force applied to the raw materials above. Since the diameter of the driven wheel below the driving chamber is smaller than the diameter of the driven wheel above the driving chamber, the transmission ratio between the lower driven wheel and the fixed wheel is greater than the transmission ratio between the upper transmission wheel and the fixed wheel, which makes the speed of the lower driven wheel faster, thereby driving the stirring blade below to rotate faster in the vertical direction, which is convenient for stirring and mixing the raw materials below. A slide groove is provided on the stirring blade, and a dredging rod is slidably installed in the slide groove; the dredging rod and the slide groove are reciprocated by The dredge rod is fixedly connected with a spring, one end of the dredge rod is a conical structure in the high-temperature and high-pressure reactor, and the other end of the dredge rod is a hemispherical structure, and the hemispherical structure fits the surface of the cam; the cam is fixedly installed on the vertical section, and the cam is located above the fixed wheel. The stirring blade drives the dredge rod in the chute to rotate horizontally in a synchronous manner during the horizontal rotation. During the rotation, one end of the hemispherical structure of the dredge rod contacts the cam surface and slides back and forth under the action of the reciprocating spring. During the reciprocating sliding of the dredge rod, one end of the conical structure thereof flips the raw materials near the inner wall of the high-temperature and high-pressure reactor to avoid the occurrence of stirring dead corners and affect the uniform distribution of the raw materials; Preferably, the stirring blade is a cross-pyramid structure, and the vertical cross-section of the stirring blade is a willow-leaf structure. The cross-pyramid structure of the stirring blade enables the stirring blade to generate a large shear force when rotating in the horizontal and vertical directions, thereby ensuring the stirring and mixing effect of the stirring blade on the raw materials. The willow-leaf structure makes the diameter of the middle end of the stirring blade larger than the diameter at both ends, similar to the symmetry of two convex structures, thereby enhancing the force of the stirring blade on the raw materials, thereby enhancing the shear force of the stirring blade on the raw materials and ensuring the mixing effect.

[0012] Preferably, the reciprocating assembly includes a fixed plate, a reciprocating rod, a rotating wheel, a driving wheel and an extrusion block; the fixed plate is fixedly connected to the dredging rod with one end provided with a conical structure, and the fixed plate is provided with a reciprocating rod in an annular array, and the dredging rod rotates synchronously with the stirring blade horizontally and vertically, thereby driving the fixed plate fixedly connected thereto to move synchronously, and at the same time, driving the fixed plate to reciprocate with itself; the reciprocating rod is provided with a scraper in a linear array, and the scraper arrangement is consistent with the shape of the stirring blade, and the fixed plate is provided with an inclined surface that cooperates with the conical structure, and the edge of the inclined surface is flush with the stirring blade; the fixed plate is provided with an inclined surface that extends the conical structure on the dredging rod, and the inclined surface and the conical structure both guide the raw materials, and the raw materials slide along the inclined surface and just enter the stirring blade, and are mixed with the raw materials in other areas following the rotation of the stirring blade, thereby improving the stirring efficiency of the stirring blade; One end of the reciprocating rod is slidably connected to the rotating wheel. During the reciprocating rod following the reciprocating motion of the dredging rod, the reciprocating rod drives the linear array of scrapers on it to move synchronously. The scrapers scrape the surface of the stirring blade to prevent the raw materials from adhering to the surface of the stirring blade, resulting in a decrease in the mixing efficiency of the stirring blade. At the same time, it prevents the raw materials from adhering to the stirring blade so that the raw materials cannot be fully mixed. The reciprocating rod cooperates with the self-rotation of the stirring blade to prevent the raw materials from adhering to the stirring blade; the rotating wheel is provided with a supporting hole that cooperates with the reciprocating rod. The supporting hole supports the reciprocating rod, so that the force at both ends of the reciprocating rod is stable, thereby ensuring the stability of the reciprocating rod movement. At the same time, the reciprocating rod drives the rotating wheel to rotate synchronously with itself by squeezing the supporting hole. A driving wheel is provided above the rotating wheel; the driving wheel is rotatably installed with the stirring shaft, and a circular array on the driving shaft There are extrusion blocks; a flipping rod is provided between the extrusion blocks; the flipping rod is arranged vertically to the stirring blade, and a linear array of shift blocks is provided on the flipping rod, which engages with the driving wheel during the rotation of the rotating wheel, driving the driving wheel to rotate, and when the driving wheel rotates, it drives the extrusion blocks in the circular array on it to rotate synchronously, and the extrusion blocks and the flipping rod rotate relative to each other, and the extrusion blocks push the flipping rod to reciprocate up and down, and the flipping rod drives the shift blocks provided thereon to move synchronously during the reciprocating motion, and the shift blocks flip the raw materials near the stirring shaft, and at the same time, cooperate with the flipping rod to rotate synchronously horizontally with the stirring shaft to achieve uniform mixing of the raw materials near the stirring shaft, and the tip of the shift block is located at the tail end of the stirring blade. The tip of the shift block is located at the tail end of the stirring blade, which can compensate for the area not stirred by the stirring blade, avoid the generation of stirring dead angles, and improve the uniformity of mixing.

[0013] Preferably, the reciprocating rod is divided into a fixed rod and a sliding rod, the fixed rod is fixedly connected to the fixed plate, a telescopic cavity is opened on the fixed plate, a sliding rod is provided in the telescopic cavity, and the sliding rod and the telescopic cavity are connected by a telescopic spring; the length of the sliding rod is greater than the length of the fixed rod, and the length of the sliding rod is greater than the length of the fixed rod, so that when the sliding rod slides in the direction of the stirring shaft, it first contacts the inner wall of the support hole, and then squeezes the telescopic spring to keep itself fixed, thereby generating relative movement with the fixed shaft, and the fixed shaft continues to slide, so that the scraper on the fixed shaft collides with the scraper on the sliding shaft, thereby generating vibration, and the raw material adhering to the scraper is shaken off by the vibration, to ensure that the raw material is prevented from adhering to the scraper and affecting the scraping effect of the scraper on the stirring blade.

[0014] Preferably, a memory metal is installed on the runner, and the memory metal is installed coaxially with the stirring blade. The memory metal is a thermal material. When the temperature rises to a certain temperature, the memory metal will expand and return to its original state. When the temperature drops, the memory metal will return to the compressed state. Therefore, when the temperature in the high-temperature and high-pressure reactor rises, the rotation speed of the stirring shaft increases, thereby increasing the rotation speed of the stirring blade. At this time, the memory metal expands to clamp the stirring blade, thereby ensuring the stability of the rotation of the stirring blade.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0021] The high-temperature high-pressure reaction kettle for preparing bean paste essence mainly comprises a high-temperature high-pressure reaction kettle, a heater, a cooling device, a stirring blade and a motor. An inlet and an outlet are formed on the high-temperature high-pressure reaction kettle for the entry of raw materials and the discharge of reaction products. The heater and the cooling device are arranged on the high-temperature high-pressure reaction kettle to control the temperature in the high-temperature high-pressure reaction kettle. The stirring blade is rotatably arranged on the central axis of the high-temperature high-pressure reaction kettle. The stirring blade and the motor are fixedly arranged. The motor is fixedly arranged on the high-temperature high-pressure reaction kettle. In production, raw materials are added into the high-temperature high-pressure reaction kettle. Then, the heater is used to heat the high-temperature high-pressure reaction kettle. At the same time, the motor is started to control the rotation of the stirring blade to mix the raw materials. After the reaction is completed, the cooling device is used to cool the high-temperature high-pressure reaction kettle. The cooled reaction products are discharged from the high-temperature high-pressure reaction kettle.

[0022] However, when the stirring blades stir the raw materials, the stirring blades do not stir the raw materials sufficiently due to the high viscosity of the raw materials, resulting in insufficient stirring effect of the raw materials, which in turn leads to uneven mixing of the raw materials, and thus the temperature cannot be quickly transferred, resulting in uneven temperature distribution inside the high-temperature and high-pressure reactor, resulting in the generation of a temperature gradient, and causing the raw materials at the bottom of the high-temperature and high-pressure reactor to coke. At the same time, during the rotation of the stirring blades, the central axis area of ​​the stirring blades is difficult to generate sufficient shear force, causing the raw materials in the center to be stirred, which in turn leads to uneven stirring in the center area. At the same time, insufficient stirring shear force of the stirring blades will cause the oxygen in the high-temperature and high-pressure reactor to be unable to be evenly distributed in the reactor, which will lead to insufficient local reactions, thereby affecting the overall quality of the product and reducing production quality.

[0023] The present invention provides a technical solution: a method and equipment for preparing hot-reaction flavor of broad bean paste: like Figures 1 to 14 As shown, a method for preparing a flavor comprises the following steps: Step 1: Mix the fermented black beans, fermented black beans and purified water and grind them; Step 2: Mix onion, garlic and purified water and beat into a paste; Step 3: Add the pretreated raw materials, mud and other auxiliary materials into a high temperature and high pressure reactor for reaction; Step 4: Cool the reaction product to 70-60°C, homogenize and then fill; Specifically, first, bean paste, fermented black beans and purified water are mixed, and the mixture is ground into a particle size of ≤5 μm by a colloid mill. Then, purple onion puree and garlic puree are evenly mixed with purified water, and filtered to form a slurry to complete the preparation of the main raw materials. The pretreated raw materials, slurry and other auxiliary materials are added to a high-temperature and high-pressure reactor, and reacted at 120° C. and 0.3 MPa for 1 hour. After the prepared bean paste heat reaction essence is cooled, it is placed in a homogenizer for refinement and uniform dispersion, and then filled to complete the production. In this embodiment, the auxiliary materials include complex amino acids, reducing sugars, nitrogen sources and spices; Specifically, through the synergistic effect of complex amino acids and reducing sugars, combined with high temperature and high pressure reactions, the layering and persistence of the sauce aroma are significantly enhanced; the heat resistance and storage stability of the flavor are improved through the nitrogen source; and the flavor and palatability of the heat-reaction flavor of the bean paste are improved through spices.

[0024] In this embodiment, the composite amino acid is a mixture of cysteine ​​hydrochloride, alanine and glycine; Specifically, cysteine ​​hydrochloride is a sulfur-containing amino acid that can generate compounds with meaty aroma in the Maillard reaction. For example, heating cysteine ​​hydrochloride with glucose, ribose, etc. can produce compounds with a beefy aroma. In addition, cysteine ​​hydrochloride works synergistically with other amino acids, such as glycine, to further enhance the complexity and softness of the flavor. Alanine has a certain umami flavor that can enhance the umami taste of food. Alanine can produce a variety of flavor compounds in the Maillard reaction. For example, when alanine reacts with reducing sugars such as glucose, it produces fruity, floral, and sweet aromas. In addition, the Maillard reaction involving alanine can also produce volatile aroma compounds such as pyrazines and furans, which can significantly enhance the flavor complexity of food. Glycine itself has a sweet taste and is used as a flavoring agent. In the Maillard reaction, glycine can synergize with other components, such as reducing sugars and cysteine, to produce a variety of flavor compounds. For example, in a glucose-cysteine ​​system, the addition of glycine can significantly enhance the meaty and roasted flavors. Glycine's participation in the reaction generates a variety of volatile and non-volatile flavor compounds. For example, in the Maillard reaction, glycine reacts with glucose to produce a caramel aroma. Furthermore, the addition of glycine can affect the concentration of specific flavor compounds, such as 1,2-ethanedithiol and 2,4,5-trimethylthiazole.

[0025] In this embodiment, the nitrogen source is yeast extract and acid-hydrolyzed plant protein powder; Specifically, the ratio of yeast extract to acid-hydrolyzed plant protein powder is 1:2; the main components of yeast extract are protein, amino acids, peptides, nucleotides, vitamins and trace elements, which are rich in nutrients and high-quality, and can improve the flavor of food, enhance freshness and flavor, reduce salt and balance odors, etc.; hydrolyzed plant protein can provide a better source of amino acids, which is easier for the human body to absorb and utilize, and provide the body with the required protein nutrition. At the same time, hydrolyzed plant protein also has certain functionality, which can extend the shelf life of food and improve the stability of food.

[0026] Preferably, the main ingredients of the bean paste flavor essence are: 110 parts of bean paste, 10 parts of fermented black beans, and 50 parts of purified water; Secondary ingredients: 70 parts onion puree, 50 parts garlic puree; Flavor enhancer: 10 parts light soy sauce, 8 parts sesame oil, 20 parts beef bone broth, 25 parts chicken paste; Spices: 1 part thirteen spices, 1 part ginger powder, 0.08 parts clove powder, 0.17 parts cinnamon powder, 1 part pepper powder; Complex amino acids: 1.6 parts xylose, 30 parts white sugar, 2 parts cysteine ​​hydrochloride, 0.7 parts alanine, 2 parts glycine; Nitrogen source: 10 parts yeast extract, 20 parts acid hydrolyzed vegetable protein powder; Flavor enhancer: MSG 5 parts, Vitamin B1 0.5 parts; The above fixedly uses the weight of bean paste as the basic unit of measurement; The above raw materials are used to prepare the hot reaction flavor of bean paste. In terms of flavor, the layering and persistence of the sauce aroma are significantly enhanced through the synergistic effect of complex amino acids and reducing sugars combined with high temperature and high pressure reaction.

The stirring blade 3 stirs and mixes in the horizontal direction to promote the reaction of the raw materials. The stirring blade 3 rotates horizontally to drive the rotating component 4 to work. The rotating component 4 drives the stirring blade 3 to rotate on itself, thereby causing the stirring blade 3 to rotate in the vertical direction, so that the stirring blade 3 transports the raw materials at the bottom upward, realizing the circulation of the raw materials in the vertical direction, and coordinating with the stirring blade 3 to follow the rotation of the stirring shaft 2 in the horizontal direction, realizing multi-angle The stirring blade 3 drives the reciprocating assembly 5 to work through the rotating assembly 4, and then drives the flipping rod 6 to slide back and forth along the central axis of the stirring shaft 2 through the reciprocating assembly 5. When the stirring blade 3 stirs the material, the shear force generated by the rotation in the circumferential area of ​​the stirring shaft 2 is small, so that the raw materials near the stirring shaft 2 are not fully stirred and mixed.

[0028] In this embodiment, the rotating assembly 4 includes a T-shaped rod 41, a fixed wheel 42, a driven wheel 43, a dredging rod 44, a reciprocating spring 45 and a cam 46; the T-shaped rod 41 is divided into a horizontal section 411 and a vertical section 412, the horizontal section 411 is a streamlined structure 4111, the horizontal section 411 is fixedly installed with the high-temperature and high-pressure reactor 1, the vertical section 412 is located in the driving chamber 21, and a linear array of fixed wheels 42 is arranged on the vertical section 412; the number of the fixed wheels 42 corresponds to the number of the stirring blades 3, and the driven wheels 43 are symmetrically arranged on both sides of the fixed wheel 42; the driven wheels 43 are rotatably connected to the inner wall of the driving chamber 21, and the driven wheels 4 3 is fixedly connected to the stirring blade 3, and the diameter of the driven wheel 43 below the driving chamber 21 is smaller than the diameter of the driven wheel 43 above the driving chamber 21; a chute 31 is provided on the stirring blade 3, and a dredging rod 44 is slidably installed in the chute 31; the dredging rod 44 is fixedly connected to the chute 31 via a reciprocating spring 45, and one end of the dredging rod 44 located in the high-temperature and high-pressure reactor 1 is a conical structure 441, and the other end of the dredging rod 44 is a hemispherical structure 442, and the hemispherical structure 442 is in contact with the surface of the cam 46; the cam 46 is fixedly installed on the vertical section 412, and the cam 46 is located above the fixed wheel 42; Specifically, the T-shaped rod 41 is fixedly installed to the high-temperature and high-pressure reactor 1 through its own horizontal section 411, thereby ensuring the overall stability of the T-shaped rod 41, so that the T-shaped rod 41 does not move. The streamlined structure 4111 of the horizontal section 411 of the T-shaped rod 41 is used to reduce the resistance between itself and the raw materials, thereby avoiding its own influence on the stirring of the raw materials. The vertical section 412 of the T-shaped rod 41 is located in the driving cavity 21 opened on the stirring shaft 2. The fixed shaft has a linear array of fixed wheels 42 corresponding to the number of layers of stirring blades 3. Driven wheels 43 are symmetrically arranged on both sides of the fixed wheel 42. The teeth of the fixed wheel 42 and the driven wheel 43 are conical wheel teeth. The driven wheel 43 is fixedly connected to the stirring blade 3. When the stirring blade 3 rotates horizontally following the stirring shaft 2, the stirring blade 3 drives the driven shaft to rotate synchronously horizontally. The driven wheel 43 engages with the fixed wheel 42 during the rotation, thereby realizing its own rotation, thereby driving the stirring The mixing blades 3 rotate synchronously to realize the self-rotation of the mixing blades 3. When the mixing blades 3 rotate, centrifugal force is generated, thereby shaking off the raw materials adhering to the mixing blades 3, reducing the adhesion of the raw materials to the mixing blades 3; the diameter of the driven wheel 43 below the driving chamber 21 is smaller than the diameter of the driven wheel 43 above the driving chamber 21. When the mixing blades 3 rotate and stir in the vertical direction, the pressure on the raw materials below is greater, so the force required to turn the raw materials below is greater than the force on the raw materials above. Since the diameter of the driven wheel 43 below the driving chamber 21 is smaller than the diameter of the driven wheel 43 above the driving chamber 21, the transmission ratio between the lower driven wheel 43 and the fixed wheel 42 is greater than the transmission ratio between the upper driving wheel and the fixed wheel 42, thereby making the speed of the lower driven wheel 43 faster, thereby driving the lower mixing blades 3 to rotate faster in the vertical direction, which is convenient for stirring and mixing the raw materials below;A chute 31 is provided on the stirring blade 3, and a dredging rod 44 is slidably installed in the chute 31. The dredging rod 44 and the chute 31 are fixedly connected by a reciprocating spring 45. The dredging rod 44 is located in the high-temperature and high-pressure reactor 1. One end of the dredging rod 44 is a conical structure 441. The conical structure 441 is used to enhance the disturbance effect of the dredging rod 44 on the raw materials and improve the mixing effect of the raw materials. The other end of the dredging rod 44 is a hemispherical structure 442. The hemispherical structure 442 fits the surface of the cam 46. The hemispherical structure 442 enhances the fit effect with the surface of the cam 46, so that the dredging rod 44 is in stable contact with the cam 46. The cam 46 is fixedly installed on the vertical section 412 and is located above the fixed wheel 42. The stirring blade 3 rotates horizontally. During this process, the dredging rod 44 in the chute 31 is driven to rotate synchronously and horizontally. During this rotation, one end of the hemispherical structure 442 of the dredging rod 44 contacts the surface of the cam 46. When the hemispherical structure 442 of the dredging rod 44 contacts the high-stroke of the cam 46, the cam 46 pushes the dredging rod 44 to slide away from the stirring shaft 2. During the sliding process, the dredging rod 44 squeezes the reciprocating spring 45. When the dredging rod 44 contacts the low-stroke of the cam 46, the dredging rod 44 is reset under the action of the reciprocating spring 45, achieving reciprocating motion. During the reciprocating sliding of the dredging rod 44, one end of its conical structure 441 stirs the raw materials near the inner wall of the high-temperature and high-pressure reactor 1, avoiding the formation of dead corners in stirring that affect the uniform distribution of the raw materials.

[0029] Preferably, an annular limit block is provided on the driven wheel 43, and a corresponding limit ring groove is provided on the inner wall of the driving cavity 21. The driven wheel 43 achieves its own height stability and ensures the stability of rotation through the annular limit block and the limit ring groove.

[0030] In this embodiment, the stirring blade 3 is a cross-pyramid structure 32, and the vertical cross-section of the stirring blade 3 is a willow-leaf structure 33; Specifically, the cross pyramid structure of the stirring blade 3 enables the stirring blade 3 to generate a large shear force when rotating in the horizontal and vertical directions, thereby ensuring the stirring and mixing effect of the stirring blade 3 on the raw materials. The willow-leaf-shaped structure 33 makes the diameter of the middle end of the stirring blade 3 larger than the diameter at both ends, similar to the symmetry of two convex structures, thereby enhancing the force of the stirring blade 3 on the raw materials, thereby enhancing the shear force of the stirring blade 3 on the raw materials and ensuring the mixing effect.

[0031] In this embodiment, the reciprocating assembly 5 includes a fixed plate 51, a reciprocating rod 52, a rotating wheel 53, a driving wheel 54 and an extrusion block 55; the fixed plate 51 is fixedly connected to the dredging rod 44 with a conical structure 441 at one end, and the reciprocating rod 52 is arranged in an annular array on the fixed plate 51. The fixed plate 51 is provided with an inclined surface 511 that cooperates with the conical structure 441, and the edge of the inclined surface 511 is flush with the stirring blade 3; the reciprocating rod 52 is linearly arrayed with a scraper 521, and the scraper 521 is arranged in a linear array with the stirring blade 3. The blades 3 are of the same shape. One end of the reciprocating rod 52 is slidably connected to the rotating wheel 53. The rotating wheel 53 is provided with a support hole 531 that cooperates with the reciprocating rod 52. A driving wheel 54 is provided above the rotating wheel 53. The driving wheel 54 is rotatably mounted on the stirring shaft 2. The driving shaft has an annular array of extrusion blocks 55. A flipping rod 6 is provided between the extrusion blocks 55. The flipping rod 6 is arranged perpendicular to the stirring blade 3. The flipping rod 6 has a linear array of shifting blocks 61, and the tip of the shifting block 61 is located at the tail end of the stirring blade 3. Specifically, the fixing plate 51 and the dredging rod 44 are fixedly connected at one end with a conical structure 441, and the dredging rod 44 rotates horizontally and vertically synchronously with the stirring blade 3, thereby driving the fixing plate 51 fixed thereto to move synchronously, and at the same time, driving the fixing plate 51 to reciprocate with itself; the fixing plate 51 is provided with an inclined surface 511 that cooperates with the conical structure 441, and the edge of the inclined surface 511 is flush with the stirring blade 3, and the fixing plate 51 is provided with an inclined surface 511 that extends the conical structure 441 on the dredging rod 44, and the inclined surface 511 is flush with the stirring blade 3. The raw materials slide along the inclined surface 511 and enter the mixing blade 3, and are mixed with the raw materials in the rest of the area as the mixing blade 3 rotates, thereby improving the mixing efficiency of the mixing blade 3; the reciprocating rod 52 is provided with a linear array of scrapers 521, and the scrapers 521 are arranged in the same shape as the mixing blade 3 to form a convex structure. During the movement of the reciprocating rod 52, the convex structure enhances the shear force of the scrapers 521, thereby reducing the resistance of the scrapers 521 during the movement, thereby improving the mixing efficiency of the reciprocating rod 52. The stability of the movement, one end of the reciprocating rod 52 is slidably connected to the rotating wheel 53. During the reciprocating movement of the reciprocating rod 52 following the dredging rod 44, the reciprocating rod 52 drives the scraper 521 of the linear array thereon to move synchronously. The scraper 521 scrapes the surface of the stirring blade 3 to prevent the raw materials from adhering to the surface of the stirring blade 3, resulting in a decrease in the mixing efficiency of the stirring blade 3. At the same time, it prevents the raw materials from adhering to the stirring blade 3 so that the raw materials cannot be fully mixed. The reciprocating rod 52 cooperates with the rotation of the stirring blade 3 to prevent the raw materials from adhering to the stirring blade 3; the rotating wheel 53 A support hole 531 is provided on the top thereof, which cooperates with the reciprocating rod 52. The support hole 531 supports the reciprocating rod 52, so that the force on both ends of the reciprocating rod 52 is stable, thereby ensuring the stability of the movement of the reciprocating rod 52. At the same time, the reciprocating rod 52 drives the rotating wheel 53 to rotate synchronously with itself by squeezing the support hole 531. A driving wheel 54 is provided above the rotating wheel 53. The gear teeth of the rotating wheel 53 and the driving wheel 54 are conical gear teeth; the driving wheel 54 is rotatably mounted on the stirring shaft 2, and a ring array of squeezing blocks 55 is provided on the driving shaft; a flipping rod 6 is provided between the squeezing blocks 55;The flipping rod 6 is arranged perpendicular to the stirring blade 3. A linear array of shifting blocks 61 is arranged on the flipping rod 6. During rotation of the rotating wheel 53, it engages with the driving wheel 54, driving the driving wheel 54 to rotate. The rotation of the driving wheel 54 drives the extrusion blocks 55 arranged in a circular array thereon to rotate synchronously. The extrusion blocks 55 rotate relative to the flipping rod 6. The extrusion blocks 55 push the flipping rod 6 up and down through the inclined slots. During the reciprocating motion of the flipping rod 6, the shifting blocks 61 provided thereon move synchronously. The shifting blocks 61 flip the raw materials near the stirring shaft 2. Simultaneously, the shifting rod 6 rotates synchronously with the stirring shaft 2 in conjunction with the horizontal rotation of the stirring shaft 2, achieving uniform mixing of the raw materials near the stirring shaft 2. The tip of the shifting block 61 is located at the rear end of the stirring blade 3. This location allows for compensatory stirring of areas not reached by the stirring blade 3, avoiding the formation of dead zones and improving mixing uniformity.

[0032] In this embodiment, the reciprocating rod 52 is divided into a fixed rod 522 and a sliding rod 523. The fixed rod 522 is fixedly connected to the fixed plate 51. The fixed plate 51 is provided with a telescopic cavity 512. The telescopic cavity 512 is provided with a sliding rod 523. The sliding rod 523 is connected to the telescopic cavity 512 via a telescopic spring 513. The length of the sliding rod 523 is greater than that of the fixed rod 522. Specifically, the length of the sliding rod 523 is greater than that of the fixed rod 522, so that when the sliding rod 523 slides toward the stirring shaft 2, it first contacts the inner wall of the support hole 531, and then squeezes the telescopic spring 513 to keep itself fixed, thereby moving relative to the fixed shaft. The fixed shaft continues to slide, causing the scraper 521 on the fixed shaft to collide with the scraper 521 on the sliding shaft, thereby generating vibration, and the raw material adhering to the scraper 521 is shaken off by the vibration, ensuring that the scraper 521 is prevented from adhering to the raw material and affecting the scraping effect of the scraper 521 on the stirring blade 3.

[0033] In this embodiment, a memory metal 532 is installed on the rotating wheel 53, and the memory metal 532 is coaxially installed with the stirring blade 3; Specifically, the memory metal 532 is a thermal material. When the temperature rises to a certain temperature, the memory metal 532 will expand and return to its original state. When the temperature drops, the memory metal 532 will return to the compressed state. Therefore, when the temperature in the high-temperature and high-pressure reactor 1 rises, the rotation speed of the stirring shaft 2 increases, thereby increasing the rotation speed of the stirring blade 3. At this time, the memory metal 532 expands to clamp the stirring blade 3, thereby ensuring the stability of the rotation of the stirring blade 3.

[0034] The present invention provides a method and equipment for preparing hot-reaction flavor of broad bean paste. The raw materials are fed into a high-temperature and high-pressure reactor 1 through a feed port, and then the motor 11 is started. The motor 11 drives the stirring shaft 2 to rotate synchronously, and the stirring shaft 2 drives the stirring blade 3 to rotate in the horizontal direction, that is, to rotate with the stirring shaft 2 as the central axis; the stirring blade 3 drives the driven wheel 43 to rotate synchronously, and the driven wheel 43 and the fixed wheel 42 rotate relative to each other. During the rotation, the gear teeth between the driven wheel 43 and the fixed wheel 42 are engaged. Since the fixed wheel 42 is fixedly connected to the fixed shaft and does not rotate, the driven wheel 43 rotates. The rotation of the driven wheel 43 drives the stirring blade 3 to rotate synchronously, and the stirring blade 3 rotates in the vertical direction, that is, it rotates with its own central axis as the axis center; during the rotation of the stirring blade 3, the dredging rod 44 slidably installed in its slide groove 31 moves synchronously. The dredging rod 44 slides along the surface of the cam 46 and cooperates with the reciprocating spring 45 to realize the reciprocating motion of the dredging rod 44. When the dredging rod 44 reciprocates, it drives the fixed plate 51 to reciprocate synchronously, and the fixed plate 51 drives the reciprocating rod 52 to move synchronously. When the reciprocating rod 52 reciprocates, the scraper 521 on the reciprocating rod 52 scrapes the surface of the stirring blade 3. At the same time, since the reciprocating rod 52 is installed on the stirring blade 3, the reciprocating rod 52 rotates synchronously with the stirring blade 3, and then the reciprocating rod 52 drives the turntable to rotate synchronously through the support hole 531. The turntable engages with the driving wheel 54 to drive the driving wheel 54 to rotate synchronously. The driving wheel 54 drives the extruding block 55 fixed thereon to move synchronously. The extruding block 55 pushes the flipping rod 6 to reciprocate through the inclined groove opened thereon. When the flipping rod 6 slides up and down, the raw materials near the stirring shaft 2 are stirred and mixed through the dial block 61.
