Description

Technical Field

[0001] This invention relates to the field of powder drying equipment technology, and in particular to a drying method and equipment for low-GI noodle premix powder. Background Technology

[0002] Premixed powder (also known as pre-mixed powder) refers to baking ingredients that are pre-mixed according to a formula and then sold to manufacturers. When producing premixed powder for low-GI noodles, various ingredients need to be made into powder and then dried to obtain the finished powder.

[0003] In existing premixed powder drying processes, the premixed powder is conveyed to a drying chamber via a conveyor belt and then heated and dried in the dryer. However, for premixed powder piled on the conveyor belt, the drying heat does not easily reach the premixed powder pressed at the bottom, resulting in incomplete drying. To address this issue, we propose a drying method and equipment for low-GI noodle premixed powder. Summary of the Invention

[0004] The purpose of this invention is to solve the problems existing in the prior art by proposing a drying method and equipment for low-GI noodle premix powder.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A drying device for low-GI noodle premix powder includes a drying shell, a separating shell, and a drying assembly. The drying shell and the separating shell are connected vertically. A filter assembly is installed at the joint between the drying shell and the separating shell. The drying assembly is installed at the top of the separating shell. An air outlet pipe is installed at the air outlet of the drying assembly and is connected to the interior of the drying shell. A dehumidifier is installed at the air inlet of the drying assembly and is connected to the interior of the separating shell. The drying assembly includes a pump.

[0007] In the drying of low-GI noodle premix powder, the pre-mixed powder is added to the drying shell. Air is supplied to the air outlet pipe through a pump, which provides airflow to the drying shell. The air blows the premix powder inside the drying shell, causing it to tumble and fly, thus drying the moist premix powder. The airflow carrying moisture passes through a filter assembly, which allows the airflow to pass through while retaining the premix powder, preventing it from overflowing. The moist airflow then enters a dehumidifier. The dehumidifier uses a heated dehumidifier, which heats and dehumidifies the airflow. The heated airflow circulates back into the drying shell. The hot air improves the drying effect, and the moisture is condensed into liquid and discharged from the dehumidifier, forming a highly efficient drying process.

[0008] Preferably, the pump is equipped with bellows at both ends, the separation shell is equipped with telescopic cylinders on the left and right outer walls, and the top of the telescopic cylinder is equipped with a top cover that cooperates with the separation shell.

[0009] The top cover can be extended and lifted by the telescopic cylinder to expose the opening at the top of the separation shell, which facilitates the maintenance of the internal filter components. The bellows can also be extended to ensure the stability of the connection of the pipeline on the pump.

[0010] Preferably, the air outlet pipe includes a dispersion pipe, an air outlet shell arranged vertically is installed at the rear end of the dispersion pipe, and a nozzle is installed at the rear end of the air outlet shell.

[0011] The dispersion tube can provide at least three air outlet manifolds, which, together with multiple air outlet shells, can provide air outlets at different heights inside the drying shell, causing the premixed powder inside to be blown and tumble. Furthermore, the multiple air outlets can create mutual turbulence, increasing the disorder of the tumbling and floating of the premixed powder, improving the contact efficiency with the airflow, and further enhancing the drying effect.

[0012] Preferably, a spray pipe is installed through the rear end of the nozzle, and the end of the spray pipe is bent to form an arc-shaped bend.

[0013] One end of the nozzle is rotatably connected to the nozzle head, and the other end of the nozzle is semi-circular. When air is being discharged, the nozzle can be rotated in the opposite direction of the air discharge by the reaction force of the airflow, which further improves the diversity of the air discharge angle and allows the premixed powder inside the drying shell to be fully tumbled and dried.

[0014] Preferably, the bottom end of the drying shell has a material outlet, a flip cover is installed on the drying shell at the material outlet, a bottom cover is installed at the front end of the flip cover, and the bottom cover is connected to the outer wall of the drying shell by a locking device;

[0015] The feed port allows for easy loading and unloading of premixed powder from the bottom. When opened, the bottom and rear sides can be opened to provide a larger opening, increasing the operating space for loading and unloading premixed powder and making it convenient to use.

[0016] Preferably, a middle frame is installed at the bottom of the separation shell, and an arc plate is installed below the opening of the middle frame in the drying shell, with the top of the arc plate bent toward the air outlet pipe.

[0017] The central frame allows for the close-fitting installation of filter components. Airflow carrying moisture and premixed powder enters the filter components through the opening in the central frame, and the arc plate blocks and redirects the airflow, while also rubbing against the premixed powder carried in the airflow to reduce the movement speed of the premixed powder. This causes the floating premixed powder to slow down and settle, thereby reducing the amount of premixed powder entering the filter components and ensuring airflow efficiency.

[0018] Preferably, the flip cover is arranged with the top end facing backward and the bottom end facing forward, and the front part of the bottom end of the drying shell is arranged with the top end facing forward and the bottom end facing backward.

[0019] The flip-top, combined with the bottom side wall of the drying shell, forms a truncated pyramid structure, reducing the space below the drying shell and decreasing the amount of premixed powder at the bottom. In addition, the tightly sealed air outlet pipes prevent excessive premixed powder from settling and being unable to be thoroughly blown away, thus improving the drying effect.

[0020] Preferably, the filter assembly includes an outer frame and a sliding shell, an outer filter screen is embedded in the vertical side wall of the outer frame, an inner filter screen is embedded in the vertical side wall of the sliding shell, and an end blade is provided at the bottom end of the sliding shell;

[0021] The outer frame is fixed, and the sliding shell can slide up and down. When too much premixed powder adheres to the outer filter screen, the airflow is reduced, and the air pressure inside the drying shell increases. This can overcome the weight of the sliding shell and make it slide up, thus exposing the upper part of the clean outer filter screen, increasing the airflow path, and reducing the air pressure inside the drying shell. As a result, the sliding shell can settle under its own weight. The premixed powder adhering to the outer filter screen can be scraped off by the end blade, thus enabling the outer filter screen to self-clean.

[0022] Preferably, the bottom side wall of the top cover is equipped with a vertical plate that cooperates with the inner filter screen, and the top of the sliding shell is provided with a through-hole that cooperates with the vertical plate;

[0023] The inner filter screen on the sliding shell can be circulated by airflow, and when the sliding shell is pushed upward by air pressure, the vertical plate can be inserted into the through-hole to scrape off the premixed powder inside the inner filter screen, ensuring a self-cleaning effect.

[0024] Preferably, a sliding pin is installed at the lower corner of the outer side of the sliding shell, and a sliding groove is provided inside the outer frame for the sliding pin to slide up and down;

[0025] By sliding the sliding pin up and down in the sliding groove, the position of the sliding shell can be limited, ensuring the stability of the sliding shell and preventing it from being pushed out of the outer frame completely by excessive air pressure when self-cleaning is ineffective, thus improving the stability of the connection.

[0026] Preferably, a method for drying low-GI noodle premix powder using a drying device includes the following steps:

[0027] 1) Add the premixed powder to the drying shell, and supply air to the air outlet pipe through the pump. The air outlet pipe provides airflow to the drying shell, and the gas blows the premixed powder inside the drying shell, causing the premixed powder to tumble and fly.

[0028] 2) The airflow carrying moisture passes through the filter assembly, which allows the airflow to pass through while leaving the premixed powder behind. The humid airflow enters the dehumidifier, which can heat and dehumidify the airflow.

[0029] 3) The heated airflow circulates into the drying shell, and the moisture is condensed into liquid and discharged from the dehumidifier. The top cover can be extended and lifted by the telescopic cylinder to expose the opening at the top of the separation shell, which is convenient for maintenance of the internal filter components. The bellows can be extended to ensure the stable connection of the pipeline on the pump.

[0030] 4) The dispersion tube can be connected to multiple air outlet shells through the air outlet manifold to provide air outlet sources at different heights inside the drying shell. One end of the nozzle is rotatably connected to the nozzle. When air is being discharged, the reaction force of the airflow can drive the nozzle to rotate in the opposite direction of the airflow direction. The airflow from multiple air outlet sources flows into each other in a turbulent manner, which improves the disorder of the tumbling and floating of the premixed powder.

[0031] Compared with existing technologies, the advantages of this drying method and equipment for low-GI noodle premix powder are as follows:

[0032] 1. The drying component is connected to an air outlet pipe with upper and lower air outlet shells. Hot air can be blown into the shell through the nozzle. The hot air, carrying moisture, passes through the filter component above and then enters the heating dehumidifier for gas-liquid separation. At the same time, the circulating hot air is supplemented and heated again to heat the premixed powder at the bottom. The hot air is sprayed out from the self-rotating nozzle, which can blow the premixed powder up and turn it over. The arc plate blocks and slows down the settling. The falling premixed powder will be blown up again by the hot air. The cycle of blowing up and settling can achieve efficient drying.

[0033] 2. Through the filter assembly, hot air carrying moisture passes through the filter screen and is discharged from the drying shell, while the premixed powder is filtered out. As the premixed powder is adsorbed on the inside of the filter screen, the airflow efficiency decreases, causing the air pressure inside the drying shell to increase. This, in turn, overcomes the weight of the sliding shell and pushes it upward, releasing the cleaning filter screen above to improve airflow efficiency. This causes the air pressure inside the drying shell to decrease, allowing the sliding shell to be moved downward by its own weight, scraping off the premixed powder inside the filter screen for self-cleaning, ensuring filtration efficiency and smooth drying.

Detailed Implementation

[0043] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0044] Reference Figure 1-8 This invention provides three technical solutions:

[0045] Example 1

[0046] A drying device for low-GI noodle premix powder includes a drying shell 1, a separating shell 2, and a drying component 3. The drying shell 1 and the separating shell 2 are connected vertically. A filter component 6 is installed at the joint between the drying shell 1 and the separating shell 2. The drying component 3 is installed at the top of the separating shell 2. An air outlet pipe 5 is installed at the air outlet of the drying component 3 and is connected to the interior of the drying shell 1. A dehumidifier 4 is installed at the air inlet of the drying component 3 and is connected to the interior of the separating shell 2. The drying component 3 includes a pump 31.

[0047] Specifically, the pump 31 is equipped with bellows 32 at both ends, and telescopic cylinders 22 are installed on the left and right outer walls of the separation shell 2. The top of the telescopic cylinder 22 is equipped with a top cover 21 that cooperates with the separation shell 2.

[0048] Furthermore, the air outlet duct 5 includes a dispersion pipe 51, with an air outlet shell 52 arranged vertically at the rear end of the dispersion pipe 51, and a nozzle 53 installed at the rear end of the air outlet shell 52.

[0049] Furthermore, a nozzle is installed through the rear end of the nozzle 53, and the end of the nozzle is bent to form an arc-shaped section 531.

[0050] In the drying of low-GI noodle premix powder, the pre-mixed powder is added to the drying shell 1. Air is supplied to the air outlet duct 5 via pump 31. The air outlet duct 5 provides airflow to the drying shell 1, causing the premix powder inside to tumble and swirl, thus drying the moist powder. The airflow carrying moisture passes through the filter assembly 6, which allows the airflow to pass through while retaining the premix powder, preventing it from overflowing. The moist airflow then enters the dehumidifier 4, which uses an HMGW-9156B heated dehumidifier to heat and dehumidify the airflow. The heated airflow circulates back into the drying shell 1. The hot air improves the drying effect, and the moisture is condensed into liquid and discharged from the dehumidifier 4, forming an efficient drying process. The top cover 21 can be extended by the telescopic cylinder 22. The opening at the top of the separation shell 2 is exposed, facilitating the inspection and maintenance of the internal filter assembly 6. The corrugated pipe 32 can be extended to ensure the stable connection of the pipeline on the pump 31. The dispersion pipe 51 can provide at least three air outlet manifolds, which, together with multiple air outlet shells 52, can provide air outlets at different heights to the inside of the drying shell 1, causing the premixed powder inside to be blown and tumble. The multiple air outlets can also create mutual turbulence, increasing the disorder of the tumbling and floating of the premixed powder, improving the contact efficiency with the airflow, and further improving the drying effect. One end of the spray pipe is rotatably connected to the nozzle 53, and the other end of the spray pipe is semi-circular. When air is being discharged, the reaction force of the airflow can drive the spray pipe to rotate in the opposite direction of the airflow, further increasing the diversity of the airflow angle and ensuring that the premixed powder inside the drying shell 1 is fully tumbled and dried.

[0051] Example 2

[0052] A drying device for low-GI noodle premix powder includes a drying shell 1, a separating shell 2, and a drying component 3. The drying shell 1 and the separating shell 2 are connected vertically. A filter component 6 is installed at the joint between the drying shell 1 and the separating shell 2. The drying component 3 is installed at the top of the separating shell 2. An air outlet pipe 5 is installed at the air outlet of the drying component 3 and is connected to the interior of the drying shell 1. A dehumidifier 4 is installed at the air inlet of the drying component 3 and is connected to the interior of the separating shell 2. The drying component 3 includes a pump 31.

[0053] Specifically, a material inlet is provided at the bottom of the drying shell 1, and a flip cover 11 is installed at the material inlet of the drying shell 1. A bottom cover 111 is installed at the front end of the flip cover 11, and the bottom cover 111 is connected to the outer wall of the drying shell 1 by a locking device.

[0054] It is worth noting that a middle frame 23 is installed at the bottom of the separation shell 2, and an arc plate 12 is installed below the opening of the middle frame 23 in the drying shell 1. The top of the arc plate 12 is bent towards the air outlet duct 5.

[0055] It is worth noting that the flip cover 11 is arranged with the top facing backward and the bottom facing forward, and the front part of the bottom of the drying shell 1 is arranged with the top facing forward and the bottom facing backward.

[0056] The feed inlet facilitates the loading and unloading of premixed powder from the bottom. When opened, the bottom and rear sides can be opened to provide a larger opening, increasing the operating space for loading and unloading premixed powder and making it convenient to use. The middle frame 23 allows for the close-fitting installation of the filter assembly 6. The airflow carrying moisture and premixed powder enters the filter assembly 6 through the opening of the middle frame 23, and the arc plate 12 blocks and reverses the airflow, and rubs against the premixed powder carried in the airflow, reducing the movement speed of the premixed powder and causing the floating premixed powder to slow down and settle, thereby reducing the amount of premixed powder entering the filter assembly 6 and ensuring airflow efficiency. The flip cover 11, together with the bottom side wall of the drying shell 1, can form a truncated pyramid structure, reducing the space under the drying shell 1 and reducing the amount of premixed powder at the bottom of the drying shell 1. In addition, the tightly pressed air outlet pipe 5 prevents excessive premixed powder from settling and being unable to be thoroughly blown away, thus improving the drying effect.

[0057] Example 3

[0058] A drying device for low-GI noodle premix powder includes a drying shell 1, a separating shell 2, and a drying component 3. The drying shell 1 and the separating shell 2 are connected vertically. A filter component 6 is installed at the joint between the drying shell 1 and the separating shell 2. The drying component 3 is installed at the top of the separating shell 2. An air outlet pipe 5 is installed at the air outlet of the drying component 3 and is connected to the interior of the drying shell 1. A dehumidifier 4 is installed at the air inlet of the drying component 3 and is connected to the interior of the separating shell 2. The drying component 3 includes a pump 31.

[0059] Specifically, the filter assembly 6 includes an outer frame 61 and a sliding shell 62. An outer filter screen 611 is embedded in the vertical side wall of the outer frame 61, and an inner filter screen 621 is embedded in the vertical side wall of the sliding shell 62. An end blade 623 is provided at the bottom end of the sliding shell 62.

[0060] Furthermore, a vertical plate 63 is installed on the bottom side wall of the top cover 21 to cooperate with the inner filter screen 621, and a through opening 624 is provided at the top of the sliding shell 62 to cooperate with the vertical plate 63.

[0061] Furthermore, a sliding pin 622 is installed at the lower corner of the outer side of the sliding shell 62, and a sliding groove 612 is provided inside the outer frame 61 for the sliding pin 622 to slide up and down.

[0062] The outer frame 61 is fixed, and the sliding shell 62 can slide up and down. Excessive premixed powder adhering to the outer filter screen 611 reduces the airflow, causing the internal air pressure of the drying shell 1 to rise. This rise overcomes the weight of the sliding shell 62, allowing it to slide upwards and expose the upper part of the clean outer filter screen 611, increasing the airflow path. This reduces the internal air pressure of the drying shell 1, allowing the sliding shell 62 to settle under its own weight. The premixed powder adhering to the outer filter screen 611 can then be scraped off by the end blade 623, allowing the outer filter screen 611 to be cleaned. For self-cleaning, the inner filter screen 621 on the sliding shell 62 can be cleaned by airflow, and when the sliding shell 62 is pushed upward by air pressure, the vertical plate 63 can be inserted into the through-hole 624 to scrape off the premixed powder inside the inner filter screen 621, ensuring the self-cleaning effect. The sliding pin 622 can slide up and down in the sliding groove 612 to limit the position of the sliding shell 62, ensuring the stability of the position of the sliding shell 62 and preventing it from being pushed out of the outer frame 61 by excessive air pressure when self-cleaning is ineffective, thus improving the stability of the connection.

[0063] The drying operation, using the aforementioned combination of drying equipment and structure for low-GI noodle premix powder, includes the following steps:

[0064] 1) Add the premixed powder to the drying shell 1, and supply air to the air outlet pipe 5 through the pump 31. The air outlet pipe 5 provides airflow to the drying shell 1, and the gas blows the premixed powder inside the drying shell 1, causing the premixed powder to tumble and fly.

[0065] 2) The airflow carrying moisture passes through the filter assembly 6. The filter assembly 6 allows the airflow to pass through while leaving the premixed powder behind. The humid airflow enters the dehumidifier 4, which can heat and dehumidify the airflow.

[0066] 3) The heated airflow circulates into the drying shell 1, and the moisture is condensed into liquid and discharged from the dehumidifier 4. The top cover 21 can be extended and lifted by the telescopic cylinder 22 to expose the opening at the top of the separation shell 2, which is convenient for the internal filter component 6 to be inspected and repaired. The bellows 32 can be extended to ensure the stable connection of the pipeline on the pump 31.

[0067] 4) The dispersion tube 51 can be connected with multiple air outlet shells 52 through the air outlet manifold to provide air outlets at different heights inside the drying shell 1. One end of the nozzle is rotatably connected to the nozzle 53. When air is being discharged, the reaction force of the airflow can drive the nozzle to rotate in the opposite direction of the airflow direction. The airflows from multiple air outlets turbulently flow with each other, improving the disorder of the tumbling and floating of the premixed powder.

[0068] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
