Description

Technical Field

[0001] This invention relates to the field of dried chili powder seasoning preparation technology, specifically to a preparation device and method for using dried chili powder seasoning. Background Technology

[0002] As a type of spice, dried chili powder is widely used in the food processing industry. To ensure its storage period and food safety, it is necessary to kill harmful microorganisms such as mold and bacterial spores attached to the powder through high-temperature steam sterilization during the production process. High-temperature steam sterilization has become the mainstream sterilization process for chili powder because it kills bacteria and leaves no chemical residues.

[0003] In existing technologies, although high-temperature steam sterilization technology can effectively sterilize chili powder and meet food safety production standards during the preparation of dried chili powder seasoning, the following defects still exist: Firstly, during the high-temperature steam sterilization process, the high-temperature and humid steam accelerates the vaporization and volatilization of natural chili essential oils on the surface of the chili powder. Existing traditional sterilization devices do not have oil-gas condensation recovery, oil-water separation, or essential oil reuse structures. The volatilized chili essential oils are directly discharged with the sterilization exhaust gas, resulting in a large loss of flavor substances. This leads to a weak spicy flavor, loss of original taste, and a decline in taste after sterilization. At the same time, it is easy to have uneven flavor in the same batch of chili powder, affecting the quality and batch stability of the finished seasoning. Secondly, the steam supply structure and the mesh cage drive structure of traditional chili powder steam sterilization devices are mostly separate and independently arranged. The two cannot achieve synchronous linkage and disassembly, making equipment assembly, maintenance, and chili powder loading and unloading procedures cumbersome and the docking accuracy poor. Moreover, the split structure has insufficient operational stability and is prone to air circuit sealing failure and transmission misalignment, resulting in uneven mesh cage rotation, insufficient chili powder agitation, and the creation of steam sterilization dead zones, which cannot meet the needs of continuous and large-scale industrial production. Third, traditional sterilization devices have a single pipeline function. Steam sterilization gas supply and flavor essential oil respraying require two independent conveying equipment and pipeline systems, which cannot achieve flexible switching between the two working conditions. This not only results in a complicated pipeline structure, high equipment manufacturing cost, and large equipment footprint, but also leads to discontinuous production process, low degree of equipment automation, and reduced overall operating efficiency of chili powder sterilization production. Summary of the Invention

The other end of the transmission gear set is connected to two rotating shafts that are inserted and engaged with the drive disk.

The inner cavity of the recovery frame is provided with a cooling tank. An air inlet pipe is provided at the bottom end of the cooling tank. A gas collecting hood is provided at the bottom end of the air inlet pipe, and the gas collecting hood communicates with the top wall of the sterilization chamber. A flared opening is provided at the top end of the air inlet pipe, and cooling pipes arranged in a ring are provided outside the flared opening.

[0012] According to some embodiments of the present invention, the top of the cooling tank is provided with a second drive motor, the power output end of the second drive motor is meshed and rotatably connected to one end of the rotating rod, a centrifugal disc is provided on the outer side wall of the rotating rod, the surface of the centrifugal disc is coated with a polytetrafluoroethylene modified oleophilic and hydrophobic coating, and a plurality of fans are also provided at one end of the rotating rod, the surface of the fans is coated with a silane composite modified titanium dioxide hydrophilic and oleophobic coating.

[0013] A method of using an apparatus for preparing dried chili powder seasoning includes the following steps: S1: Fill the dried chili powder to be sterilized into the mesh cage, and push the walking frame carrying the mesh cage into the sterilization chamber; manually rotate the threaded rod to drive the clamping blocks on both sides to move towards each other, and use the arc-shaped bayonet to clamp and position the mesh cage and the side plate to achieve the mesh cage limit and fixation. S2: Start the hydraulic push rod to push the protective frame to slide horizontally along the base towards the sterilization chamber. The limit rod limits the sliding stroke. During the sliding process, the sealed plug-in port on the positioning frame is sealed and plugged into the quick interface at the end of the side plate. At the same time, the diamond-shaped plug-in end of the drive motor and the positioning strip are embedded into the diamond-shaped opening and positioning hole of the drive plate, completing the synchronous docking of the steam passage with the shaft and drive plate. S3: Start the electric heating steam generator 2 to prepare high-temperature steam, turn on the gas pump, and send the high-temperature steam into the spray bar through the high-temperature steam pipe, the diversion valve pump, the sealed metal hose, and the sealed plug port. The steam is then sprayed into the inside of the net cage through the nozzle. Simultaneously start the drive motor 1. The power is transmitted to the drive disc through the transmission gear set and the rotating shaft, which drives the net cage to rotate at a constant speed on the roller of the walking frame. This continuously turns the chili powder to eliminate sterilization dead corners and completes the high-temperature steam sterilization. S4: During the sterilization process, drive motor two is started, driving the rotor to rotate the fan and centrifugal disc synchronously; the fan generates negative pressure, drawing the steam exhaust gas mixed with chili oil in the sterilization chamber into the cooling tank through the gas collection hood and air inlet pipe; the annular cooling pipe cools and condenses the mixed gas, and the silane composite modified titanium dioxide hydrophilic and oleophobic coating on the fan surface adsorbs water vapor. The water vapor is centrifuged and thrown to the inner wall of the cooling tank, collected in the water storage area, and discharged through the drain pipe; the gas phase of chili oil is adsorbed by the polytetrafluoroethylene modified hydrophilic and oleophobic coating on the surface of the centrifugal disc, and thrown into the oil collection hopper under the action of centrifugal force. The oil and water are separated by the polytetrafluoroethylene hydrophobic and oleophobic filter cloth, and the chili oil penetrates the filter cloth and flows into the oil storage area through the oil delivery pipe and oil collection pipe for storage; S5: After the sterilization process is completed, turn off the air pump, operate the diversion valve pump to cut off the high-temperature steam pipe passage, and open the essential oil pipeline in the oil storage area; the chili essential oil in the oil storage area is sent into the spray bar through the diversion valve pump 68 and the sealed metal hose, and is evenly sprayed onto the surface of the sterilized chili powder by the nozzle; after the aroma is replenished, turn off drive motor one and drive motor two, control the hydraulic push rod to pull the protective frame to reset, disconnect the air circuit from the plug-in transmission connection of the rotating shaft and drive plate, loosen the fixing clamp, pull out the walking frame 3, take out the net cage, and the finished chili powder can be taken out.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention, by installing a cooling recovery component at the top of the sterilization chamber, can rapidly cool and condense the high-temperature steam and chili oil mixture generated during sterilization. Simultaneously, it utilizes the selective permeability and adsorption properties of the silane-modified titanium dioxide hydrophilic and oleophobic coating on the fan surface, the polytetrafluoroethylene modified oleophilic and hydrophobic coating on the centrifuge disc surface, and the polytetrafluoroethylene hydrophobic and oleophilic filter cloth. Combined with centrifugal rotation, this achieves efficient physical separation of water vapor and chili oil, recovering the natural chili oil lost during sterilization. Furthermore, through pipelines and a diversion valve pump, the recovered and purified natural essential oil is sprayed back onto the surface of the sterilized chili powder. This overcomes the shortcomings of traditional high-temperature steam sterilization processes, such as essential oil volatilization, flavor loss, and uneven aroma in the finished product. It eliminates the need for artificial flavoring, maximizing the preservation of the natural spicy flavor of the chili powder and improving the quality and batch stability of the finished seasoning.

[0015] 2. This invention, by setting up a sliding air supply component and a drive component, and driving the protective frame to slide horizontally via a hydraulic push rod, enables the synchronous docking and separation of the steam gas path structure composed of a sealed plug-in port and a quick-connect interface, and the plug-in transmission structure composed of a transmission gear set, a rotating shaft, and a drive disc. This achieves integrated and rapid connection, assembly, and disassembly of the steam supply end and the mechanical drive end. Compared with the shortcomings of traditional preparation devices where the air supply structure and drive structure are set up separately, disassembly and assembly are cumbersome, and docking accuracy is poor, the preparation device of this invention achieves the linkage and synchronous operation of the gas path and the plug-in transmission structure. Material handling, equipment maintenance, and switching of working conditions are more convenient. At the same time, it can ensure stable sealing of the gas path and reliable transmission during the sterilization process of the rotating mesh cage, eliminate sterilization dead corners, and is suitable for continuous and large-scale industrial production.

[0016] 3. This invention, by setting up a multi-functional diversion valve pump, simultaneously connects the high-temperature steam pipe and the oil collection pipe, allowing for flexible switching of the passage state according to the production process. This enables seamless switching between two operating modes: high-temperature steam supply sterilization and pressurized re-spraying of natural essential oils. During the sterilization process, the high-temperature steam pipe is opened while the essential oil pipeline is cut off to ensure stable high-temperature sterilization conditions. After sterilization, the steam passage is cut off while the essential oil pipeline is opened, enabling the transportation and re-spraying reuse of the recovered essential oils. A single device integrates both gas supply and oil supply functions, eliminating the need for additional independent conveying equipment. This simplifies the overall piping structure, reduces manufacturing costs and floor space, and simultaneously improves the automation level and operational continuity of the entire device.

[0021] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0022] like Figures 1-12 As shown, a preparation device for dried chili powder seasoning includes: a sterilization chamber 1 and an electric heating steam generator 2. The electric heating steam generator 2 is a commercially available standard device, which heats water to generate high-temperature saturated steam to provide a stable steam source for the high-temperature sterilization process of chili powder in the sterilization chamber 1. The inner cavity of the sterilization chamber 1 is provided with a walking frame 3, and two mesh cages 4 are rotatably connected inside the walking frame 3. Each of the two mesh cages 4 is rotatably connected to a side plate 5. One end of the side plate 5 is provided with a quick-connect interface 51, and the other end of the side plate 5 is provided with a spray bar 52. An air supply component 6 is provided on one side of the sterilization chamber 1. One end of the air supply component 6 is provided with a drive component 7 that is connected to the mesh cages 4. The top of the sterilization chamber 1 is provided with a cooling recovery component 8 that is connected to the air supply component 6.

[0023] Using the sterilization chamber 1 as the main cavity for sterilization, it works in conjunction with four modules: steam generation, material carrying, transmission and air supply, and flavor recovery. It integrates high-temperature sterilization of chili powder, material turning, oil and gas recovery, and essential oil re-spraying. The structure is compact and the components are highly interconnected, which can effectively realize automated sterilization and flavor restoration of chili powder, solving the problems of single function and fragmented processes in traditional preparation devices.

[0024] The top of the walking frame 3 is provided with a fixing clamp 31, which includes two clamping blocks 311. The two clamping blocks 311 are connected by a threaded rod 312. The ends of the two clamping blocks 311 that are close to each other are provided with arc-shaped slots 313. The bottom of the walking frame 3 is provided with multiple rotating rollers 32 that rotate and fit with the bottom of the net cage 4. The bottom of the walking frame 3 is provided with multiple universal wheels 33.

[0025] By setting the threaded adjustable fixing clamp 31, the wire mesh cage 4 and the side plate 5 can be clamped and positioned. The arc-shaped bayonet 313 has a high fit and is firmly fixed, effectively preventing the overall structure from loosening or shifting during the operation of the device. The bottom roller 32 forms rolling support for the wire mesh cage 4, reducing rotational friction resistance and ensuring the smooth operation of the wire mesh cage 4. The casters 33 facilitate the overall movement of the walking frame 3 and the loading and unloading of materials, improving the convenience of device operation and maintenance.

[0026] Two mesh cages 4 are provided with an installation frame 41 at their center, and two fixing frames 42 are provided on both sides of the mesh cage 4. The side wall of the fixing frame 42 is provided with an annular groove. The inner cavity of the fixing frame 42 is also provided with multiple connecting rods 43. One end of the multiple connecting rods 43 is connected to a drive disk 44. Multiple positioning holes 441 are provided on the outer side wall of the drive disk 44, and a diamond-shaped opening 442 is provided in the center of the drive disk 44.

[0027] The frame structure of the mesh cage 4, including the mounting frame 41, the fixing frame 42, the connecting rod 43, and the drive plate 44, are used to connect the drive plate 44 and the mesh cage 4, so that the transmission force is even. With the help of the diamond-shaped opening 442 and the positioning hole 441, the drive plate 44 and the mesh cage 4 can be quickly inserted and aligned, with good anti-rotation positioning effect, ensuring stable power transmission. At the same time, the annular groove provides a limiting space for the rotation of the side plate 5, realizing the separation of dynamic and static, and avoiding mutual interference between the transmission and air supply structures.

[0028] The side plate 5 is rotatably connected to the inner cavity of the annular groove, and one end of the spray bar 52 is L-shaped and connected to the nozzle 521.

[0029] The rotational cooperation between the side plate 5 and the annular groove enables the mesh cage 4 to rotate while the air supply structure remains fixed, thus solving the defects of easy tangling and loosening of the air circuit interface in traditional rotating sterilization devices. The L-shaped spray bar 52, in conjunction with the spray head 521, can discharge material into the mesh cage 4 from multiple angles, ensuring uniform spraying of steam and essential oils without any dead angles, and guaranteeing uniform sterilization and fragrance replenishment effects.

[0030] The air supply assembly 6 includes a base 61 connected to the side wall of the sterilization chamber 1. A protective frame 62 is slidably connected to the top of the base 61. One end of the protective frame 62 is provided with a hydraulic push rod 63 and multiple limit rods 64. The other ends of the hydraulic push rod 63 and the limit rods 64 are both connected to the side wall of the base 61. A positioning frame 65 is provided at the top of the protective frame 62. The top of the positioning frame 65 is provided with two sealed insertion ports 66 that are engaged with the quick-connect interface 51. The other end of the sealed insertion port 66 is provided with a sealed metal hose 67. The other end of the sealed metal hose 67 is connected to a diversion valve pump 68. One end of the diversion valve pump 68 is also connected to a high-temperature steam pipe 69. The other end of the high-temperature steam pipe 69 is connected to an air supply pump 610. The air supply pump 610 is installed at the top of the sterilization chamber 1. The other end of the air supply pump 610 is connected to an electrically heated steam generator 2 through a pipe.

[0031] The sliding air supply component 6 and the hydraulic push rod 63 enable the protective frame 62 to slide smoothly into position. The limiting rod 64 ensures the sliding accuracy and enables the quick sealing and connection and disconnection of the air passage port and the quick interface 51 of the mesh cage 4. The high-temperature steam pipe 69 and the essential oil delivery pipeline are integrated through the diversion valve pump 68, which can flexibly switch between steam sterilization and essential oil back spraying without replacing pipeline equipment. The sealed metal hose 67 adapts to structural displacement and ensures the sealing of the air and liquid passages throughout the process, simplifying the device structure and improving the efficiency of process switching.

[0032] The drive assembly 7 includes a drive motor 71 located inside the protective frame 62. The output end of the drive motor 71 is provided with a transmission gear set 72. The other end of the transmission gear set 72 is connected to two rotating shafts 73 that are inserted into the drive disk 44. One end of the rotating shaft 73 is provided with a diamond-shaped insertion end 731 and a plurality of positioning strips 732 that are inserted into the positioning hole 441.

[0033] Through the linkage and sliding of the drive component 7 and the air supply component 6, the plug-in transmission structure consisting of the rotating shaft 73, the drive disk 44, and the transmission gear set 72 is synchronously connected and disassembled with the steam gas path structure consisting of the sealed plug-in port 66 and the quick interface 51, without the need for separate alignment and debugging. The rotating shaft 73 adopts multiple positioning with the diamond plug-in end 731 and the positioning strip 732, which has high plug-in accuracy and stable transmission torque, and can prevent transmission slippage and misalignment. The power is smoothly transmitted through the transmission gear set 72, driving the mesh cage 4 to rotate at a uniform speed, ensuring that the material is turned evenly and eliminating dead corners in steam sterilization.

[0034] The cooling recovery assembly 8 includes a recovery frame 81 located at the top of the sterilization chamber 1. A cooling tank 82 is located within the inner cavity of the recovery frame 81. An air inlet pipe 83 is located at the bottom of the cooling tank 82, and a gas collection hood 84 is located at the bottom of the air inlet pipe 83. The gas collection hood 84 communicates with the inner top wall of the sterilization chamber 1. A horn-shaped opening 85 is located at the top of the air inlet pipe 83, and cooling pipes 86 arranged in a ring are located outside the horn-shaped opening 85. The input end of the cooling pipes 86 passes through the top of the cooling tank 82, and the output end of the cooling pipes 86 passes through the bottom of the cooling tank 82. A partition 87 is located at the bottom of the inner cavity of the cooling tank 82. An oil storage area 871 is located at the bottom of the partition 87, and multiple oil collection pipes 88 are inserted into the bottom of the oil storage area 871. The other end is connected to the adjacent diversion valve pump 68; the top of the partition 87 is a water storage area 872, and a drain pipe 89 is inserted into the inner wall of the water storage area 872. Multiple oil supply pipes 810 are provided through the top of the partition 87, and the tops of the multiple oil supply pipes 810 are connected to an oil collection hopper 811. The oil collection hopper 811 is installed on the inner top wall of the cooling pipe 86. The oil collection hopper 811 is arranged in a ring shape. The bottom of the ring shape of the oil collection hopper 811 is provided with a polytetrafluoroethylene hydrophobic and oleophilic filter cloth 812. The top opening of the oil collection hopper 811 is inclined. The top of the cooling tank 82 is provided with a gas supply pipe 813. The bottom of the gas supply pipe 813 is arranged in an unfolded shape. The inner cavity of the gas supply pipe 813 is rotatably connected to a rotating rod 814.

[0035] By setting up a closed cooling and recovery component 8, the vapor and essential oil mixture in the sterilization chamber is collected from all directions by the gas collection hood 84, and the annular cooling pipe 86 achieves rapid and uniform cooling and condensation of the mixture. The partition 87 separates the oil storage area 871 and the water storage area 872, achieving preliminary oil and water partition storage. With the selective permeability of the inclined open annular oil collection hopper 811 and the polytetrafluoroethylene hydrophobic and oleophilic filter cloth 812, the oil phase is intercepted and the water phase overflows and separates. It can efficiently recover the natural chili essential oil lost during the sterilization process, and at the same time realize the recycling of water resources. It has a high degree of integration and good oil and gas recovery and separation effect.

[0036] The top of the cooling tank 82 is equipped with a second drive motor 815. The power output end of the second drive motor 815 is meshed and rotatably connected to one end of the rotating rod 814. The outer wall of the rotating rod 814 is equipped with a centrifugal disc 816. The surface of the centrifugal disc 816 is coated with a polytetrafluoroethylene modified oleophilic and hydrophobic coating. One end of the rotating rod 814 is also equipped with multiple fans 817. The surface of the fans 817 is coated with a silane composite modified titanium dioxide hydrophilic and oleophobic coating.

[0037] By combining the differential separation of the double coating with centrifugal negative pressure, the fan 817 rotates to generate negative pressure suction, actively extracting the mixed oil and gas. At the same time, the silane composite modified titanium dioxide hydrophilic and oleophobic coating adsorbs water vapor and collects it by centrifugal force. The hydrophilic and oleophobic coating on the surface of the centrifugal disc 816 can adsorb gaseous essential oils, and then the essential oils are thrown into the oil collection hopper 811 by high-speed centrifugal force to complete enrichment. By utilizing the material properties and centrifugal action, high-precision physical separation of water vapor and essential oils is achieved, improving the purity and recovery rate of chili essential oil recovery, providing high-quality raw materials for subsequent in-situ re-spraying to replenish aroma, and making up for the loss of flavor after the sterilization of chili powder.

[0038] Working principle: The chili powder to be processed is filled into the inside of the mesh cage 4, and then the assembled mesh cage 4 is placed on the walking frame 3; the threaded rod 312 is manually rotated to drive the clamping blocks 311 on both sides to move closer together, and to complete the clamping and positioning of the quick interface 51; the electric heating steam generator 2 is started, and the high temperature and high pressure steam generated is transported to the inside of the mesh cage 4 through the air pump 610; since the side plate 5 and the fixed frame 42 are connected by a rotary rotation, the quick interface 51 will not rotate synchronously when the mesh cage 4 rotates, so that the quick interface 51 and the sealed plug port 66 can always be kept in a sealed docking state, ensuring that the high temperature steam is stably introduced into the spray bar 52 and evenly sprayed out by the nozzle 521, so as to perform high temperature sterilization treatment on the chili powder in the cage; The rotation drive process of the mesh cage 4 is as follows: The hydraulic push rod 63 is activated, pushing the protective frame 62 to slide horizontally along the base 61, causing the protective frame 62 to move closer to the sterilization chamber 1. During the movement, the drive motor 71 and the transmission gear set 72 move synchronously, achieving the matching of the sealed plug-in port 66 and the quick-connect interface 51. At the same time, the diamond-shaped plug-in end 731 and the positioning strip 732 of the rotating shaft 73 are respectively embedded in the diamond-shaped opening 442 and the positioning hole 441 of the drive disk 44. The drive motor 71 outputs power, which is transmitted through the transmission gear set 72, the rotating shaft 73, and the drive disk 44, driving the mesh cage 4 to rotate smoothly on the rotating roller 32 of the walking frame 3. The powder is turned synchronously with the mesh cage 4, which can avoid the problem of material accumulation and obstruction, and eliminate the dead corners of steam sterilization. The air supply component 6 can connect and disconnect with the wire mesh cage 4 according to the production conditions, and the connection parts are easy to disassemble and assemble. Compared with the traditional integrated rigid connection, the preparation device of the present invention can realize the synchronous linkage of the air supply channel and the drive mechanism for plugging and separating operations, effectively simplifying the disassembly and maintenance procedures of the air supply component 6 and the drive component 7, reducing the difficulty of device maintenance and material loading and unloading, and adapting to large-scale continuous sterilization production conditions. During the sterilization process, the drive motor 815 is started, driving the rotor 814 to drive the centrifuge disc 816 and the fan 817 to operate synchronously. The preparation device of this invention adopts a partitioned design with gas phase separation in the upper part of the cooling tank 82 and liquid phase storage in the lower part. The fan 817 only draws and guides the mixed gas phase, while the condensed and stratified liquid oil and water are placed in the static area in the lower part of the cooling tank 82, unaffected by airflow disturbance. With the differentiated selective separation characteristics of the polytetrafluoroethylene modified oleophilic and hydrophobic coating on the surface of the centrifuge disc 816 and the silane composite modified titanium dioxide hydrophilic and oleophobic coating on the surface of the fan 817, no secondary emulsification of oil and water will occur during the operation of the device, ensuring the separation accuracy and stability of oil and water. The rotation of fan 817 creates a negative pressure suction effect, drawing out the sterilized water vapor and chili oil mixed in the gas phase from the sterilization chamber 1, causing the mixed airflow to flow towards the air delivery pipe 813; the surface of centrifugal disc 816 is coated with a polytetrafluoroethylene modified oleophilic and hydrophobic coating, and the surface of fan 817 is coated with a silane composite modified titanium dioxide hydrophilic and oleophobic coating; water vapor easily adheres to the coating surface of fan 817, and is centrifugally thrown towards the inner wall of cooling tank 82 as the fan rotates, then gathers in water storage area 872, and is finally discharged through drain pipe 89; chili oil cannot adhere to the surface of fan 817 and is continuously transported upward with the airflow. After the chili oil vapor comes into contact with the centrifugal disc 816, it is adsorbed and captured by the hydrophobic and oleophilic coating on the disc surface. Under the action of centrifugal force, it is thrown into the oil collection hopper 811. Since the density of chili oil is less than that of water, the chili oil accumulates on the polytetrafluoroethylene hydrophobic and hydrophobic filter cloth 812, and the condensed water droplets float on the surface of the oil. When the height of the mixed liquid exceeds the inclined upper edge of the oil collection hopper 811, the surface water overflows into the water storage area 872, thereby achieving efficient physical separation of water vapor and chili oil. The chili oil collected at the bottom of the oil collecting hopper 811 can penetrate the polytetrafluoroethylene hydrophobic and oleophilic filter cloth 812 and be collected in the oil storage area 871 through the oil collecting pipe 88. After the sterilization process is completed, the air pump 610 is turned off, and the diversion valve pump 68 is operated to cut off the passage of the high-temperature steam pipe 69 and open the essential oil delivery pipeline. The stored natural chili oil is pressurized and transported. The chili oil flows through the sealed metal hose 67 and the spray bar 52 in sequence, and is finally evenly atomized and sprayed onto the surface of the sterilized chili powder by the nozzle 521. This compensates for the natural flavor substances lost during the high-temperature sterilization process, so that the finished chili powder retains its original spicy flavor, achieves uniform flavor throughout the batch of materials, and effectively improves the overall quality of the seasoning.
