Microbial solid fermentation drying equipment

Abstract

The invention relates to microbial solid fermentation drying equipment which comprises a storage cavity used for loading materials, and the core of the scheme is as follows: one cavity wall of the storage cavity is configured to be movable and is loaded on the materials; the hot air flow circularly passes through the storage cavity and pushes the movable cavity wall of the storage cavity to move in the process of entering the storage cavity so as to trigger the materials to move. Through the structural concept design that the inner wall of the storage cavity can move during air inlet, when feed particles are air-dried in the whole scheme, the cavity wall shakes to enable the feed particles to longitudinally shake, so that the loosening effect is achieved while drying is carried out, permeation of hot air among the particles is promoted, and the drying efficiency is improved. And meanwhile, compared with the prior art, the mode that the particles are directly and rigidly disturbed by a mechanical structure is avoided, so that the situation that the particles are crushed is effectively reduced.

Description

Technical Field

[0001] This invention relates to microbial processing equipment, specifically to a microbial solid fermentation and drying equipment. Background Technology

[0002] After being fermented by microorganisms, feed can effectively increase the content of certain components (such as amino acids), thereby increasing its nutritional value. After fermentation, the feed naturally contains a certain amount of moisture. After being made into pellets, it requires further drying to control the moisture content within a certain range for more stable storage. In current technology, when feed pellets are dried, the equipment also needs to agitate them. During this agitation, the mechanical agitation may cause the pellets to scatter, which is detrimental to the subsequent packaging process. Summary of the Invention

[0003] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0004] To address the technical problem that existing drying equipment easily crushes feed pellets during operation, the present invention provides the following technical solution: A microbial solid-state fermentation drying device includes a storage chamber, and: The storage cavity is used to load materials, and one of its cavity walls is configured to be movable and support the materials; The hot airflow circulates within the storage cavity and, during its entry into the storage cavity, pushes the movable cavity wall to move, thereby contacting and moving the material.

[0005] As a preferred technical solution for a microbial solid fermentation drying device, the storage chamber is provided with an air inlet and a movably disposed sealing component. The sealing component covers the air inlet, the material is pressed against the sealing component, and the hot airflow enters the storage chamber through the air inlet and pushes the sealing component.

[0006] As a preferred technical solution for a microbial solid fermentation drying device, the number of air inlets is multiple, and the hot airflow is configured to pass through the multiple air inlets sequentially.

[0007] As a preferred technical solution for a microbial solid fermentation drying device, it also includes an air inlet chamber for gas collection, which is connected to a storage chamber through multiple air inlets. A shielding component is movably disposed in the air inlet chamber to shield the air inlet, and during its movement, it sequentially unshields one of the air inlets.

[0008] As a preferred technical solution for a microbial solid fermentation drying device, the pressure inside the air inlet chamber is configured to be greater than the pressure inside the storage chamber, and the pressure inside the air inlet chamber is kept depressurized when it reaches a threshold.

[0009] As a preferred technical solution for a microbial solid fermentation drying device, an exhaust component is rotatably arranged inside the storage cavity, and a guide channel leading to the outside of the storage cavity is constructed on it. During the exhaust process, the guide channel acquires potential energy to maintain the rotation of the exhaust component. When the device is rotating, the shielding component sequentially unblocks one of the air inlets and connects to the exhaust component.

[0010] As a preferred technical solution for a microbial solid fermentation drying device, the exhaust component is provided with a material leakage port, a rotary nozzle, and a discharge port that communicate with the flow guide channel, and an adjusting component is movably provided. When the airflow is discharged from the rotary nozzle, the exhaust component is kept to acquire potential energy. When the adjusting component is moved to the first position, the material leakage port and the discharge port are kept closed, while the rotary nozzle is kept open. When the adjusting component is moved to the second position, the material leakage port and the discharge port are kept open, while the rotary nozzle is kept closed.

[0011] As a preferred technical solution for a microbial solid fermentation drying device, the rotating nozzle is kept open when the pressure inside the storage chamber reaches a threshold.

[0012] As a preferred technical solution for a microbial solid fermentation drying device, the material outlet, the rotary nozzle, and the discharge port are longitudinally distributed, and the adjusting component is longitudinally slidably mounted on the exhaust component.

[0013] As a preferred technical solution for a microbial solid fermentation drying device, the exhaust mechanism is further provided with a rotational driving force, and the exhaust mechanism maintains its rotation when the pressure in the storage chamber does not reach the threshold.

[0014] The microbial solid fermentation drying equipment provided by this invention has the following beneficial effects: 1. This invention utilizes a structural design that allows the inner wall of the storage cavity to move during air intake. This design enables the feed pellets to vibrate longitudinally during the drying process by the vibration of the cavity wall itself. This achieves a loosening effect while drying, promoting thorough penetration of hot air between the pellets. Compared to existing technologies, this design avoids the process of mechanical structures directly agitating the pellets, thus effectively reducing the occurrence of pellet crushing.

[0015] 2. This invention uses the concept of pressurizing the drying airflow to increase the temperature of the airflow itself, thereby improving the drying effect. At the same time, it reduces the power input of electric heating and effectively controls the energy consumption of the entire solution. Attached Figure Description

Therefore, the invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0029] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0030] Example: In the existing technology, in order to ensure the drying effect, some stirring elements need to be set in the drying box. While the feed is being dried by hot air, it is being raked or agitated by the stirring elements, so as to achieve the effect of turning the feed inside and out. When the mechanical structure moves inside the pellet pile, some pellets will inevitably be crushed. Based on the above, regarding the methods used in this solution, such as... Figure 1-5As shown: A microbial solid fermentation drying device includes a drying chamber 1 for loading feed pellets. A receiving hopper 2 is configured at the bottom of the drying chamber 1. After the dried feed is discharged from the bottom of the drying chamber 1, it can be unloaded into the receiving hopper 2. The bottom of the drying chamber 1 has a conical structure. A rotating column 3 is rotatably installed at the center of the conical surface. The rotating column 3 is a vertical tubular structure, and its bottom end extends into the receiving hopper 2. A sieve frame 4 is installed at the top of the drying chamber 1. When feeding into the drying chamber 1, the top cover of the chamber is opened, and the feed pellets can directly pass through the sieve frame 4 into the chamber. An extension pipe 5 is fixedly installed on the sieve frame 4, and one end of the extension pipe extends downward and is rotatably connected to the rotating column 3. A discharge port 6 is constructed on the rotating column 3 at the lowest point of the conical surface. It is connected to the inside of the rotating column 3. When unloading, the pellets enter the inside of the rotating column 3 through the discharge port 6 and fall into the receiving hopper 2. Furthermore, the bottom of the drying chamber 1 is also provided with an air inlet chamber 7. The top wall of the air inlet chamber 7 is a planar structure, and multiple air inlets 8 are constructed between the top surface and the conical surface of the drying chamber 1 to maintain communication. The multiple air inlets 8 are arranged in a ring array around the circumference of the rotating column 3. The rotating column 3 passes through the air inlet chamber 7, and its penetration point on the wall of the air inlet chamber 7 is set with a sealed rotational fit. A baffle plate 9 is also fixedly installed around the circumference of the rotating column 3 and fits against the top wall of the air inlet chamber 7. The fitting point is equipped with a ball bearing structure, so that the two surfaces can flexibly move relative to each other. The baffle plate 9 can seal and cover multiple air inlets 8. One part of the baffle plate 9 has a notch 10, so that when the baffle plate 9 rotates, the notch 10 will connect with one of the air inlets 8 in turn. That is, during the rotation, the baffle plate 9 can release the obstruction of one of the air inlets 8 in turn. An air compressor 11 and an electric heating wire (the electric heating wire is not shown in detail in the attached figure) are arranged on the air inlet chamber 7. The air compressor 11 is used to compress external air into the air inlet chamber 7. The air is then heated by the electric heating wire and enters the drying chamber 1 through the air inlet 8. Furthermore, multiple sealing plates 12 are rotatably mounted on the conical surface inside the drying chamber 1, each corresponding to a multiple air inlet 8. The sealing plates 12 seal and cover the corresponding air inlets 8. Normally, the sealing plates 12 hang down under their own gravity, thus sealing and covering the air inlets 8. When air pressure rushes into the drying chamber 1 from the air inlets 8, it can push the sealing plates 12. Through the free rotation setting, the sealing plates 12 are lifted by the air pressure. In order to limit the maximum rotation angle of the sealing plates 12, the rotation fit between the sealing plates 12 and the chamber wall is made with a corner limit treatment, so that the maximum rotation angle of the sealing plates 12 when they are lifted does not exceed 30 degrees. Furthermore, such as Figure 6As shown, the rotating column 3 has at least two rotating nozzles 13 extending laterally around its periphery. When the rotating nozzles 13 expel air, the resulting thrust allows the rotating column 3 to rotate. Inside the rotating column 3, a sliding piston 14 is connected by a spring. The piston 14 is located at the rotating nozzles 13 and blocks the rotating nozzles 13. When the internal pressure of the rotating column 3 increases to a certain level, it pushes the piston 14 to overcome the spring force and move a certain distance, thereby allowing the rotating nozzles 13 to pass through and release air. A blocking block 15 is also vertically slidably installed inside the rotating column 3. Specifically, such as Figure 7 As shown, during the drying operation, the block 15 is slid to its upper limit position (which can be understood as the first position). At this time, it seals the discharge port 6 and the bottom opening of the rotating column 3. The space between the middle cavity of the rotating column 3 and the rotating nozzle 13 is open, preventing particles from leaking out of the chamber, and allowing air pressure to be released through the rotating nozzle 13. Figure 8 As shown, during unloading, the block 15 is kept sliding to the lower limit position (which can be understood as the second position). At this time, the block 15 blocks the space between the middle of the rotating column 3 and the rotating nozzle 13. At this time, the discharge port 6 and the bottom port of the rotating column 3 are opened, and the feed particles in the bin fall into the discharge port 6 and pass through the rotating column 3, finally falling to the discharge point to realize the unloading process. Furthermore, an electric motor is fixedly installed at the bottom of the drying chamber 1, and a toothed disc is fixedly installed on the rotating column 3, maintaining a transmission connection with the electric motor. After the feed pellets to be dried are loaded into the drying chamber 1, air is compressed into the air inlet chamber 7 by the air compressor 11. The electric motor drives the rotating column 3 to rotate synchronously, thereby causing the baffles 9 to rotate synchronously. The air compressed into the air inlet chamber 7 is heated by the heating wire and then continuously enters the drying chamber 1 through multiple air inlets 8. During this process, the hot air, due to the high pressure, pushes the baffles 9 to be lifted. Multiple baffles 9 are lifted in sequence, thereby creating a longitudinal shaking effect on the feed pellets in various places. At the same time, combined with the driving effect formed by the hot airflow flowing from bottom to top, it can effectively prevent the feed pellets at the bottom from being compacted, thereby ensuring that the hot airflow flows and penetrates fully between the feed pellets to ensure the drying effect. Compared with the existing technology, the drying chamber 1 does not have a mechanical stirring component directly installed, thereby reducing the occurrence of feed pellets being crushed. Based on the above process, when the amount of air entering the drying chamber 1 reaches a certain level, the chamber is under high pressure, and the temperature of the compressed air will be further increased. At this time, when the air compressor 11 is compressing air, the power of the heating wire can be appropriately reduced to reduce energy consumption. When the feed pellets are under high pressure, they become more compact due to the pressure, thereby improving their anti-crushing effect. When the chamber is under a certain high pressure, the high pressure will push the piston 14 to move a certain distance, thereby causing the rotating nozzle 13 to release air. The airflow flows out of the drying chamber 1 and passes through the rotating column 3 as follows: Figure 7 As shown by the middle arrow, the block 15 is in the first position at this time. During this process, the rotating nozzle 13 obtains the reverse thrust to keep the rotating column 3 driving the baffle plate 9 to rotate synchronously, so as to maintain the function of supplying air from the air inlet chamber 7 to the drying chamber 1. At this time, the motor can stop working. The continuous air intake and exhaust cycle in the air inlet chamber can maintain the rotation of the rotating column 3. In addition, the maximum air supply speed of the air inlet 8 is slightly less than the compressor speed of the air compressor 11, so that the pressure in the air inlet chamber 7 is greater than the pressure in the drying chamber 1, thereby increasing the speed at which the airflow enters the drying chamber 1 from the air inlet 8, so as to improve the impact effect on the sealing plate 12. Specifically, this solution also includes a humidity sensor for detecting the drying results. The sensor can be located inside the extension tube 5 or inside the drying chamber. When the humidity in the airflow is detected to be less than a certain value, the entire system can stop working. For the material cutting process, such as Figure 3 , 4 as well as Figure 9 As shown, an electric push rod 16 is also fixedly installed inside the receiving hopper 2. The movable end of the electric push rod 16 is rotatably connected to the block 15. The movement of the electric push rod 16 can control the up and down movement of the block 15, realizing the switching between the first position and the second position. When discharging, the block 15 is moved to the lower limit position, so that the material can be unloaded. The path of the feed through the inside of the rotating column 3 is as follows: Figure 8 As shown by the middle arrow; in addition, the top cover of the drying chamber 1 is equipped with a corresponding pressure relief valve. When unloading, the pressure inside the chamber can be slowly released through the pressure relief valve to prevent the unloading speed from being too fast.

[0031] In summary, compared with existing technologies, this solution does not add any overly complex configurations or structures to achieve the above effects, thus ensuring drying quality while effectively controlling costs.

[0032] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0033] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
