Description

Technical Field

[0001] This invention relates to the field of bran steaming equipment technology, and more particularly to an automatic bran steaming method and system, and more specifically to an automatic bran feeding method and system. Background Technology

[0002] Rice husks are an indispensable solid filler and leavening agent in the brewing of baijiu, especially strong-aroma baijiu. They provide a large surface area to support the proliferation and metabolism of microorganisms during the fermentation process. However, rice husks are prone to moisture and mold during storage and transportation, and they contain a large amount of raw rice husk flavor and bitter substances. Therefore, in actual production, it is necessary to remove the off-flavors and raw rice husk flavor by steaming the rice husks.

[0003] CN115044434A discloses a rice bran steaming and cooling machine, including a casing, an exhaust fan assembly, and several cooling fans. The casing is equipped with a rice bran steaming conveyor belt and a cooling conveyor belt. A steam supply pipe is connected to the bottom of the casing, and ventilation holes are provided on the peripheral wall of the casing. The exhaust fan assembly includes an exhaust duct connected to the top of the casing and at least two exhaust pipes connected to the exhaust duct. The exhaust pipes are arranged at intervals along the direction of the rice bran steaming conveyor belt, and each exhaust pipe is equipped with an exhaust fan. Several cooling fans are respectively arranged below the cooling conveyor belt for blowing gas upward to cool the rice bran husks.

[0004] Existing automated bran steaming systems typically include a scraper conveyor and a steamer. During steaming, the scraper conveyor and other transport equipment move the bran husks to the steamer for steaming. The discharge port of the scraper conveyor is connected to the feed port of the steamer to form a feeding channel. However, existing technology cannot prevent the steam generated during steaming from entering the scraper conveyor through the feeding channel, causing the scraper conveyor to easily develop an odor. Secondly, after the steam generated during steaming enters the scraper conveyor, the bran husks carried in the steam can easily adhere to the inner wall of the scraper conveyor, leading to bacterial growth inside the scraper conveyor, which in turn corrodes the scraper conveyor and causes it to malfunction. Steam can also overflow through the joints of the scraper conveyor and condense inside the scraper, producing condensate that drips down along the joints, affecting the production environment.

[0005] Furthermore, on the one hand, there are differences in understanding among those skilled in the art; on the other hand, the applicant studied a large number of documents and patents when making this invention, but due to space limitations, not all details and contents were listed in detail. However, this does not mean that the present invention does not possess the features of these prior art. On the contrary, the present invention already possesses all the features of the prior art, and the applicant reserves the right to add relevant prior art to the background art. Summary of the Invention

[0006] In view of the shortcomings of the prior art, the present invention provides an automatic method and system for steaming rice bran, which aims to solve at least one or more technical problems existing in the prior art.

[0007] To achieve the above objectives, the present invention provides an automatic bran steaming system, more specifically an automatic bran steaming feeding system, comprising:

[0008] Steaming device for rice bran;

[0009] A feeding device is controllably arranged upstream of the rice husk steaming device to provide rice husk material to be processed;

[0010] A buffer bin is arranged between the feeding device and the steaming device to contain and allow the bran material to enter the feeding channel of the steaming device. A baffle curtain that can move to accommodate the movement of the bran material is arranged at the junction of the feeding channel and the buffer bin.

[0011] in,

[0012] The buffer bin is configured to adjust the material level inside the bin based on information about the internal environment, so that the baffle curtain can move according to changes in the material level inside the bin to limit the amount of steam flowing into the buffer bin via the steaming device.

[0013] This invention transforms an open material conveying method into a closed or semi-closed material transport channel by setting up a buffer chamber between the feeding device and the steaming device. By pre-piling the material in the buffer chamber before steaming, the material effectively blocks the channel between the steaming and feeding devices, preventing steam generated during steaming from flowing back to the feeding device via the buffer chamber. Furthermore, this invention includes several freely suspended strip-shaped baffles at the connection between the buffer chamber and the steaming device (e.g., the outlet of the buffer chamber). During steaming, these baffles contact and adhere to the material, and can deflect along a predetermined conveying direction under the influence of the material. The baffles and the flowing material together form a sealing surface that prevents steam backflow in the conveying direction of the feed channel. Without interfering with continuous material conveying, the baffles reduce the amount of steam entering the buffer chamber from the steaming device, thus preventing steam from entering the feeding device via the buffer chamber and causing odors, corrosion, or even malfunctions in the feeding device.

[0014] Preferably, the buffer silo adjusts the material level in the silo based on the internal environment information as follows: Based on the temperature and humidity information of the buffer silo, the movement of one or more material layer height adjustment units arranged in the feeding channel relative to the feeding channel is adjusted so that the material layer height adjustment units can adjust the material level in the silo in a way that blocks part of the rice husk material so that it enters the feeding channel in layers and / or in a time sequence.

[0015] Preferably, the buffer bin is further configured to adjust the material level in the bin in a manner that correlates the material level information in the bin obtained by at least one material level acquisition unit with the feeding speed of the feeding device for the buffer bin.

[0016] Preferably, the movement of the material layer height adjustment unit relative to the feeding channel can be adjusted in relation to the temperature and humidity information of the buffer bin, the material level in the bin, and / or the feeding speed of the feeding device, so that the bran material entering the feeding channel can form a conveying speed difference corresponding to different material layer heights by being restricted by the material layer height adjustment unit. In this invention, a material layer height adjustment unit is provided in the feeding channel connecting the bran steaming device and the buffer bin, which can adjust the steaming height of the material in the bran steaming device. This material layer height adjustment unit can be driven in response to changes in temperature and humidity in the buffer bin to move in the conveying direction intersecting with the bran material, thereby preventing some bran material from continuously entering the downstream of the feeding channel. This causes the bran material to stratify in the feeding channel and generate different conveying speeds. Based on the difference between the conveying speed difference and the bran feeding speed, the material gap between the buffer bin and the feeding channel can be compensated, thereby avoiding the formation of a steam backflow space between the buffer bin and the bran steaming device, preventing excessive steam backflow to the feeding device, causing odor, corrosion, or even damage, and affecting the continuity of the bran steaming process. In addition, when the material level adjustment unit adjusts the material level in the buffer bin, the feeding speed of the feeding device is adjusted according to the real-time changes in the material level in the bin and the feeding status, so as to reduce steam backflow and prevent material from overflowing the buffer bin, thus ensuring the efficiency of the steaming process.

[0017] Preferably, in this invention, the adjustment of the material level in the buffer silo based on the internal environment information can be performed in conjunction with the material level information acquired by at least one material level acquisition unit and / or the feeding speed of the feeding device. In this invention, when adjusting the movement of the material layer height adjustment unit based on the temperature and humidity information of the buffer silo, it is also necessary to adjust the material level in the silo based on the real-time material level of the buffer silo and the feeding speed of the feeding device. For example, if the buffer silo has a high material level and the feeding speed of the feeding device is high, in addition to adjusting the movement of the material layer height adjustment unit to adjust the material level in the silo, it is also necessary to adaptively reduce the feeding speed of the feeding device to reduce the steam return flow while preventing excessive material from overflowing the buffer silo.

[0018] Preferably, the automatic rice bran steaming system provided by the present invention may further include a material discharge adjustment unit disposed at the feed inlet of the buffer bin. The material discharge adjustment unit is used to adjust the material conveying direction of the feeding device for the buffer bin so as to adjust the material level in the buffer bin.

[0019] Preferably, in this invention, the material discharge adjustment unit adjusts the material conveying direction of the feeding device to adjust the material level in the buffer bin, which can be performed in conjunction with the temperature and humidity information of the buffer bin, the material level information in the bin, and / or the feeding speed of the feeding device. To avoid data acquisition errors from the level sensor causing misalignment of the discharge pile and resulting in localized gaps in the buffer bin, the material discharge adjustment unit adjusts the discharge point of the rice husk material entering the buffer bin based on the real-time performance of the buffer bin's temperature and humidity information, material level information, and / or the feeding speed of the feeding device. This changes the material accumulation state within the buffer bin and prevents steam from flowing into the buffer bin and creating gaps.

[0020] Preferably, the present invention also relates to an automatic bran steaming method, more specifically an automatic bran steaming and feeding method, which can utilize the automatic bran steaming system or automatic bran steaming and feeding system provided by the present invention. Specifically, the automatic bran steaming method or automatic bran steaming and feeding method may include:

[0021] A feeding device is provided for supplying rice husk material to be processed to a rice husk steaming device;

[0022] A buffer chamber is provided between the feeding device and the steaming device, and the buffer chamber is controllably connected to the feeding channel of the steaming device. A baffle curtain that can move to adapt to the movement of the rice husk material is provided at the junction of the feeding channel and the buffer chamber.

[0023] The material level inside the buffer bin is adjusted based on the internal environment information, so that the baffle curtain can move according to the changes in the material level inside the bin to limit the amount of steam flowing into the buffer bin through the steaming device.

[0024] Preferably, in this invention, adjusting the material level within the buffer silo based on the silo's internal environmental information includes:

[0025] Based on the temperature and humidity information of the buffer silo, the movement of one or more material layer height adjustment units deployed in the feeding channel relative to the feeding channel is adjusted so that the material layer height adjustment units can adjust the material level in the silo in a manner that blocks part of the rice husk material so that it enters the feeding channel in layers and / or in a time sequence.

[0026] Preferably, the automatic bran steaming method or automatic bran feeding method provided by the present invention further includes:

[0027] The material level in the buffer silo is adjusted by relating the material level information in the silo obtained by at least one material level acquisition unit to the feeding speed of the feeding device for the buffer silo.

[0028] During the steaming of rice bran, this invention adjusts the feeding speed of the feeding unit and / or the steaming height of the steaming device according to the temperature and humidity of the buffer silo to dynamically adjust the material level in the buffer silo. Under the condition of ensuring smooth steaming, this invention ensures the uniformity of material accumulation in the buffer silo, so that the steam entering the buffer silo through the material gaps can be fully absorbed by the material, thereby reducing or preventing the steam generated in the steaming device from flowing back to the feeding device through the material gaps.

Detailed Implementation

[0037] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more explicit definition of the scope of protection of the present invention.

[0038] This invention provides an automatic bran steaming system, and more specifically relates to an automatic bran steaming feeding system, such as... Figure 1As shown, the system may include:

[0039] Steaming device 130 for steaming rice husks;

[0040] The feeding device 110 is controllably arranged upstream of the steaming device 130 to provide the steaming device 130 with the rice husk material to be processed.

[0041] A buffer bin 120 is arranged between the feeding device 110 and the steaming device 130 to hold and allow the bran material to be processed to enter the feeding channel 131 inside the steaming device 130.

[0042] According to a preferred embodiment, the automatic bran steaming system further includes an industrial controller for performing data processing and equipment control. Specifically, the industrial controller can be used to control the activation of the feeding device 110 and adjust the feeding speed of the feeding device 110, and / or control the activation of the bran steaming device 130 and adjust the steaming speed of the bran steaming device 130 (such as material conveying speed, adjusting steam supply). In particular, the industrial controller may include any one or more of a microprocessor, central processing unit, microcontroller, digital signal processor, or similar device, or a combination thereof.

[0043] According to a preferred embodiment, the rice bran steaming device 130 is used to steam rice bran husk material. Specifically, the rice bran steaming device 130 can be a device used for distillation and impurity removal during the brewing process of baijiu (Chinese liquor), such as a distillation still or a rice bran cooling machine. As a non-limiting example, taking a rice bran cooling machine as an example, the rice bran steaming device 130 may include a housing and a conveyor belt 132 disposed inside the housing for conveying rice bran husk material, as well as a cooling conveyor belt (not shown in the figure) disposed at the outlet end of the conveyor belt 132. The portion corresponding to the conveyor belt 132 is the steaming section. The portion corresponding to the cooling conveyor belt is the cooling section.

[0044] According to a preferred embodiment, the bottom of the steaming device 130 may be connected to a steam supply pipe corresponding to the conveyor belt 132 for inputting steam into the steaming device 130. Furthermore, the bottom of the steaming device 130 may also be equipped with a cooling fan corresponding to the cooling conveyor belt for blowing gas to cool the rice husks.

[0045] According to a preferred embodiment, the top of the casing of the rice bran steaming device 130 may be provided with multiple steam outlets for steam discharge. The rice bran steaming device 130 is connected to the steam discharge unit 133 through the steam outlets on the top of its casing.

[0046] According to a preferred embodiment, the steam discharge unit 133 connected to the top of the steaming device 130 may include one or more steam discharge pipes that allow steam to be discharged, and power equipment (such as pumps or fans) connecting each steam discharge pipe for guiding and extracting steam from the steam discharge pipes.

[0047] According to a preferred embodiment, the feeding device 110 is arranged upstream of the steaming device 130 to provide rice husk material to the steaming device 130 for steaming. Specifically, in this invention, the feeding device 110 may be a scraper conveyor.

[0048] According to a preferred embodiment, such as Figure 1 and Figure 2 As shown, a buffer chamber 120 is provided between the feeding device 110 and the steaming device 130 to buffer the rice husk material and connect the two devices. Specifically, the top inlet of the buffer chamber 120 is connected to the discharge port of the feeding device 110. The bottom and a portion of the sidewalls near the bottom of the buffer chamber 120 form a discharge port, which is connected to the inlet of the feeding channel 131 inside the steaming device 130. The rice husk material provided by the feeding device 110 enters the feeding channel 131 inside the steaming device 130 through the buffer chamber 120 and is delivered downstream of the channel by the conveyor belt 132 laid at the bottom of the feeding channel 131, thereby filling the feeding channel 131 with the rice husk material in a substantially uniform manner so that the steaming device 130 can steam the rice husk material in the feeding channel 131.

[0049] According to a preferred embodiment, such as Figure 2 As shown, the sidewall of the buffer bin 120 opposite the discharge port is constructed as an inclined surface, allowing the rice husk material accumulated in the buffer bin 120 to move towards the discharge port and the feed channel 131 using the potential energy provided by the inclined surface. Therefore, when no material accumulates at the discharge port of the buffer bin 120, the rice husk material falling onto the inclined sidewall moves along the bottom inclined surface of the buffer bin 120 to enter the conveyor belt 132 laid at the bottom of the feed channel 131. When material accumulates at the discharge port of the buffer bin 120, the inclined surface at the bottom of the buffer bin 120 causes the rice husk material to move laterally, thus allowing the rice husk material to enter the rice steaming device 130 when the buffer bin 120 is connected to the feed channel 131.

[0050] According to a preferred embodiment, such as Figure 3As shown, when the steaming device 130 is used to perform the steaming operation, the outlet of the buffer chamber 120 is connected to the feed channel 131 of the steaming device 130. In the unused space (i.e. the connection gap that is not filled with material) between the feed channel 131 and the buffer chamber 120, a steam backflow channel is formed, which allows the steam generated by steaming to enter the buffer chamber 120 from the feed channel 131 through the connection gap between the feed channel 131 and the buffer chamber 120. Once the steam from steaming enters the buffer chamber 120, it is very likely that the steaming steam containing odor will flow back to the feeding device 110, thereby causing odor, corrosion or even damage to the feeding device 110.

[0051] According to a preferred embodiment, such as Figure 2 As shown, the buffer bin 120 may also be provided with one or more observation windows 124 for observing the material accumulation status. Specifically, the observation windows 124 may be provided in any one or all of the top, middle and bottom of the buffer bin 120. This is an illustration of a non-limiting example. Figure 2 As shown, the observation window 124 can be located below the second material level acquisition unit 122.

[0052] According to a preferred embodiment, to prevent the steam generated in the steaming device 130 from entering the buffer chamber 120 and ultimately the feeding device 110, such as... Figure 2 As shown, in this invention, a plurality of strip-shaped baffle curtains 134 are arranged at the connection between the discharge port of the buffer bin 120 and the feed channel 131 of the steaming device 130. Specifically, the plurality of strip-shaped baffle curtains 134 hang freely from the top of the feed channel 131 from top to bottom, and the baffle curtains 134 can move to adapt to the movement of the material.

[0053] Specifically, such as Figure 4 As shown, when the rice husk material enters the feed channel 131 through the blocking curtain 134 under the action of the conveyor belt 132, the blocking curtain 134 can deflect to adhere to the material under the push of the material, that is... Figure 4 The baffle curtain 134 shown deflects in the direction of material movement. In the direction opposite to the material channel 131, the baffle curtain 134 and the rice husk material accumulated in the feeding channel 131 together form a closed space, filling the gap between the feeding channel 131 and the baffle curtain 134 or buffer chamber 120. Thus, without interfering with the continuous material transport and ensuring the continuity of the rice husk steaming process, the baffle curtain 134, which can flexibly move with the material migration, restricts the entry of steaming rice husk into the buffer chamber 120. In this invention, the baffle curtain 134 can be made of high-temperature resistant food-grade silicone material, thereby ensuring the safety and environmental protection of the rice husk steaming process and avoiding the introduction of harmful impurities.

[0054] According to a preferred embodiment, before the steaming device 130 is started, in order to avoid insufficient bran material provided by the feeding device 110 (such as a scraper conveyor), the material can be pre-accumulated in the buffer bin 120 between the steaming device 130 and the feeding device 110, so as to block the steam from the steaming device 130 from entering the channel connected to the feeding device 110 by the pre-accumulated bran material.

[0055] According to a preferred embodiment, such as Figure 2 As shown, a material discharge adjustment unit 111 can be provided at the discharge port where the feeding device 110 connects to the buffer bin 120. Alternatively, a material discharge adjustment unit 111 can be provided at the inlet at the top of the buffer bin 120. Specifically, as... Figure 5 As shown, the material dropping adjustment unit 111 can adjust the dropping point or accumulation position of the material in the buffer bin 120 by deflecting the output direction of the material.

[0056] As a non-limiting example, the material feeding adjustment unit 111 can be a guide plate equipped with a rotary motor. By controlling the movement direction and angle of the guide plate, the position of the material falling into the buffer bin 120 can be changed. Specifically, when feeding material into the buffer bin 120, the material feeding adjustment unit 111 can change the direction in which the material enters the buffer bin 120 so that the material falls into different positions in the buffer bin 120, thereby adjusting the material accumulation state inside the buffer bin 120. For example, the material can be accumulated in a basically uniform manner or more material can be accumulated to the target position (such as the middle or one side of the buffer bin), thereby avoiding misaligned material falling into the buffer bin 120 and causing local gaps, so that a space for steam recirculation is formed between the buffer bin 120 and the steaming device 130.

[0057] Specifically, the material discharge adjustment unit 111 can change the accumulation position of the material in the buffer bin 120 by deflecting the conveying direction, so that the material blocks the gas communication between the buffer bin 120 and the feed channel 131 as much as possible, thereby reducing or avoiding the space for steam backflow between the buffer bin 120 and the feed channel 131. It should be understood that the present invention does not intend to improve the material discharge adjustment unit 111, and therefore its specific structure is not described in detail.

[0058] According to a preferred embodiment, to further avoid the formation of a steam backflow space between the buffer chamber 120 and the feed channel 131, such as... Figure 2As shown, one or more material layer height adjustment units 135 may be provided at the top of the feed channel 131 or above the conveyor belt 132. Specifically, the material layer height adjustment unit 135 may be arranged on the side of the feed channel 131 near the outlet of the buffer bin 120. Alternatively, the material layer height adjustment unit 135 may be arranged opposite to the side of the baffle curtain 134 facing the feed channel 131. Further, the material layer height adjustment unit 135 may be arranged in the feed channel 131 along the height direction of the feed channel 131, thereby partially or completely dividing the feed channel 131.

[0059] According to a preferred embodiment, such as Figure 6 As shown, the material layer height adjustment unit 135 can adjust the stacking height of material from the buffer bin 120 on the conveyor belt 132 by changing its own length. Specifically, the material layer height adjustment unit 135 may include a length-adjustable baffle, one end of which is disposed at the top of the feed channel 131, and the other end as a movable free end. More specifically, the material layer height adjustment unit 135 can move up and down in response to a drive from the system controller to adjust the stacking height of material on the conveyor belt 132 by adjusting the distance between its free end and the conveyor belt 132.

[0060] According to a preferred embodiment, such as Figure 6 As shown, when the material layer height adjustment unit 135 is arranged between the front end and the rear end of the feeding channel 131, the material layer height adjustment unit 135 can form a physical barrier with the material accumulated at the bottom of the feeding channel 131 to block the steam from flowing to the inlet of the feeding channel 131 and the buffer chamber 120, so as to prevent the steam from steaming bran from flowing back to the feeding device 110 from the gap between the buffer chamber 120 and the feeding channel 131 (i.e., the area not filled by bran material). Specifically, when the material moves into the downstream of the feed channel 131 along the conveyor belt 132, the material with a stacking height higher than the free end of the material layer height adjustment unit 135 is blocked, while the material with a stacking height lower than the free end of the material layer height adjustment unit 135 moves into the downstream of the feed channel 131 along the conveyor belt 132. Thus, the material that is separated and stacked to the downstream of the feed channel 131 by the material layer height adjustment unit 135 separates the rear section of the feed channel 131 from the front section, thereby restricting the movement of the steam from the bran steam toward the buffer bin 120.

[0061] This invention prevents steam generated during rice bran steaming from flowing back to the feeding device 110 by setting a baffle curtain 134 and a material layer height adjustment unit 135 in the feeding channel 131. However, since there are gaps between the materials, these gaps can form a gas passage connecting the rice bran steaming device 130 and the feeding device 110. Furthermore, because the gaps between the materials are small, steam is easily adsorbed onto the materials when flowing through the gaps, meaning the materials can also adsorb steam to prevent it from entering the feeding device 110 along the channels formed by the gaps. However, if the amount of steam entering the materials is too large, causing the materials to become oversaturated with steam, the steam can still enter the feeding device 110 through the buffer chamber 120 along the channels formed by the gaps. On the other hand, if the material layer thickness in the buffer chamber 120 is large, the resistance to the upward steam will be greater, so the steam will flow towards other spaces with relatively less resistance.

[0062] Therefore, to prevent the excess unadsorbed steam from flowing into the feeding device 110 through the gaps between the materials due to oversaturation of the material, the buffer chamber 120 is configured to adjust the material level within the chamber based on the internal environmental information. This allows the baffle curtain 134 at the junction of the buffer chamber 120 and the feeding channel 131 to move based on changes in the material level within the buffer chamber 120, thereby limiting the amount of steam flowing into the buffer chamber 120 via the steaming device 130. Specifically, the system controller can adjust the material height in the buffer chamber 120 by monitoring changes in temperature and humidity, thereby reducing or preventing the formation of a steam backflow space between the buffer chamber 120 and the steaming device 130.

[0063] According to a preferred embodiment, a material level acquisition unit connected to a system controller signal may be configured inside the buffer hopper 120. Specifically, as shown... Figure 2 As shown, the material level acquisition unit may include a first material level acquisition unit 121 and a second material level acquisition unit 122. Further, the first material level acquisition unit 121 is a high-level sensor, which can be positioned high near the top of the buffer hopper 120. The second material level acquisition unit 122 is a low-level sensor, which can be positioned low near the bottom of the buffer hopper 120. That is, the first material level acquisition unit 121 can be positioned above the second material level acquisition unit 122. Both the first material level acquisition unit 121 and the second material level acquisition unit 122 can be material level sensors. The above-described configuration of the material level acquisition units is merely an illustrative example without limitation. Those skilled in the art will understand that more material level acquisition units can be configured, and these material level acquisition units can be positioned at any location other than those described above, as needed.

[0064] According to a preferred embodiment, in response to the material level information acquired by the first material level acquisition unit 121 and the second material level acquisition unit 122, the system controller can divide the material height in the buffer bin 120 into at least a first material height exceeding the first material level acquisition unit 121, a second material height between the first material level acquisition unit 121 and the second material level acquisition unit 122, and a third material height below the second material level acquisition unit 122.

[0065] According to a preferred embodiment, such as Figure 2 As shown, the buffer chamber 120 is also equipped with one or more temperature and humidity acquisition units 123 that are signal-connected to the system controller. As a non-limiting example, the temperature and humidity acquisition units 123 can be arranged between the first material level acquisition unit 121 and the second material level acquisition unit 122, near the first material level acquisition unit 121, and near the second material level acquisition unit 122, or all of these locations. Preferably, the temperature and humidity acquisition units 123 can be arranged near the inlet or outlet of the buffer chamber 120. The temperature and humidity acquisition units 123 can be temperature and humidity sensors. Specifically, since the rice husk material absorbs steam heat, causing the temperature to rise, the system controller can determine the absorption status of the rice husk material in the buffer chamber 120 for steaming based on the environmental information inside the buffer chamber 120 obtained by the temperature and humidity acquisition unit 123, such as the temperature and humidity information inside the chamber. In particular, when the temperature and humidity information inside the buffer chamber 120 exceeds the set threshold, it can be considered that the amount of steam retained in the buffer chamber 120 has exceeded the maximum adsorption capacity of the stored material, and thus the unadsorbed steam enters the buffer chamber 120, significantly increasing the temperature inside the chamber.

[0066] According to a preferred embodiment, when the steaming device 130 is used to perform the steaming process, the system controller can obtain the temperature and humidity information inside the buffer bin 120 through the temperature and humidity acquisition unit 123, and adjust the material level inside the buffer bin 120 according to the temperature and humidity value inside the buffer bin 120, thereby reducing or avoiding the occurrence of empty space between the buffer bin 120 and the feeding channel 131 that forms a steam upward channel (which can also be figuratively called a "steam short circuit").

[0067] Specifically, when the temperature and humidity values ​​inside the buffer chamber 120 exceed a set threshold, the system controller can adjust the material level in the buffer chamber 120 by changing the feeding rate of the buffer chamber 120. For example, when the temperature and humidity values ​​inside the buffer chamber 120 exceed the set threshold, the system controller can increase the feeding rate of the buffer chamber 120 to increase the material accumulation height in the buffer chamber 120, thereby replenishing the buffer chamber 120 with material that has not adsorbed vapor.

[0068] The reasons why steam reaches the buffer chamber 120 may include: the material, the baffle curtain 134, and the material layer height adjustment unit 135 failing to block the connection between the buffer chamber 120 and the feed channel 131, creating a space for steam backflow between the material gaps. Alternatively, the material in the buffer chamber 120 may have reached saturation in adsorbing steam, creating a space for steam backflow between the material gaps, causing the steam to flow back to the feeding device 110 along the channel formed by the material gaps.

[0069] According to a preferred embodiment of the present invention, the buffer bin 120 is configured to adjust the movement of one or more material layer height adjustment units 135 arranged in the feed channel 131 in the direction intersecting the feed channel 131 based on temperature and humidity information, so as to allow the material layer height adjustment units 135 to adjust the material level in the buffer bin 120 in such a way as blocking part of the rice husk material so that it enters the feed channel 131 in a time sequence.

[0070] According to a preferred embodiment, when the material height in the buffer bin 120 is at the first material height, i.e., exceeding the material level line of the first material level acquisition unit 121, the system controller can control the material layer height adjustment unit 135 in the feeding channel 131 to move towards the bottom conveyor belt 132 of the feeding channel 131, thereby reducing the steaming height inside the feeding channel 131 of the steaming device 130. This reduces the channel area / size at the connection between the buffer bin 120 and the feeding channel 131, thereby reducing the discharge speed of the buffer bin 120. Correspondingly, the amount of steam entering the buffer bin 120 from the connection between the buffer bin 120 and the feeding channel 131 also decreases, allowing the material stored in the buffer bin 120 to have sufficient adsorption capacity for the steam entering it. In addition, when the material in the buffer bin 120 exceeds the first material level acquisition unit 121, there is a risk of material overflowing the buffer bin 120. At this time, the feeding device 110 can be driven to reduce the discharge speed of the material entering the buffer bin 120.

[0071] According to a preferred embodiment, the movement distance of the material layer height adjustment unit 135 relative to the bottom conveyor belt 132 of the feed channel 131 can be adjusted in association with the temperature and humidity information within the buffer bin 120. That is, the obstruction area (such as a vertical obstruction surface) formed by the material layer height adjustment unit 135 in the conveying direction of the feed channel 131 can be determined based on the temperature and humidity information within the buffer bin 120. Furthermore, the movement distance of the material layer height adjustment unit 135 relative to the bottom conveyor belt 132 of the feed channel 131 can also be adjusted based on the material level information of the buffer bin 120.

[0072] Specifically, when the feeding speed of the feeding device 110 is constant and the conveying speed of the feeding channel 131 is constant, the material content in the buffer bin 120 remains stable. Therefore, by controlling the movement of the material layer height adjustment unit 135 in the direction intersecting with the feeding channel 131 (such as the vertical direction), a conveying speed difference is generated between the upper and lower material layers in the feeding channel 131. The limitation of the conveying speed difference on the steam backflow of the steam can be reflected in the temperature and humidity information changes in the buffer bin 120. In view of this, the system controller can adjust the movement distance of the material layer height adjustment unit 135 relative to the bottom conveyor belt 132 of the feeding channel 131 according to the temperature and humidity information in the buffer bin 120, and further adjust the movement of the material layer height adjustment unit 135 (such as further lowering or raising) based on the adjusted temperature and humidity information changes.

[0073] According to a preferred embodiment, since the buffer chamber 120 continuously feeds and discharges, the buffer chamber 120 continuously replenishes materials that have not adsorbed steam and discharges materials that have adsorbed steam. This ensures that the materials stored in the buffer chamber 120 can continuously adsorb the steam entering the buffer chamber 120, thereby reducing the amount of steam flowing back to the feeding device 110.

[0074] According to a preferred embodiment, the buffer bin 120 is further configured to adjust the material level within the bin by associating the material level information acquired by at least one material level acquisition unit (i.e., the first material level acquisition unit 121 and / or the second material level acquisition unit 122) with the feeding speed of the feeding device 110 for the buffer bin 120. Specifically, for example, when the material height in the buffer bin 120 is a second material height between the first material level acquisition unit 121 and the second material level acquisition unit 122, the system controller sends a control command to increase the speed of the feeding device 110 to increase the material in the buffer bin 120. Furthermore, when the material level in the buffer bin 120 is lower than the material level line corresponding to the second material level acquisition unit 122, and the feeding speed of the feeding device 110 is too low, the system controller sends a control command to increase the speed of the feeding device 110. Therefore, while ensuring the steaming efficiency of the steaming device 130, the supplementary material in the buffer silo 120 is increased to reduce the ratio of steam entering the buffer silo 120 to the material stored in the buffer silo 120, thereby increasing the amount of material in the buffer silo 120 that can adsorb steam, thus enhancing the adsorption effect of the material in the buffer silo 120 on steam and reducing the amount of steam returned to the feeding device 110.

[0075] According to a preferred embodiment, when the material discharged from the buffer bin 120 moves laterally along the feed channel 131, the material layer height adjustment unit 135 in the feed channel 131 moves towards the bottom conveyor belt 132 of the feed channel 131. The material moving along the conveyor belt 132 will be blocked by the material layer height adjustment unit 135 and experience resistance in the opposite direction of the conveying direction, so that more material layers bear pressure towards the buffer bin 120. As a result, the topmost material layer is blocked by the material layer height adjustment unit 135 first, and the material layer below it moves along the predetermined conveying direction of the feed channel 131. Thus, there is a conveying speed difference between the upper and lower material layers in the predetermined conveying direction of the feed channel 131. Based on this, the system controller adjusts the relationship between the conveying speed difference and the feeding speed of the feeding device 110. By utilizing the dynamic difference compensation mechanism between the conveying speed difference and the chaff replenishment speed, the possibility of idle space between the buffer bin 120 and the feed channel 131, especially between the bottom of the buffer bin 120 and the top of the feed channel 131, is greatly reduced.

[0076] According to a preferred embodiment, when the temperature and humidity values ​​in the buffer chamber 120 do not exceed the set threshold, it indicates that the material content currently stored in the buffer chamber 120 is sufficient or the amount of steam entering the buffer chamber 120 is low. The material layer height adjustment unit 135 can be shortened (i.e., moved in the direction away from the bottom conveyor belt 132 of the feed channel 131) or the feeding device 110 can be driven to increase the material supply speed, so as to increase the steaming efficiency of the steaming device 130 without steam returning to the feeding device 110.

[0077] According to a preferred embodiment, when the feeding device 110 stops transporting materials or completes material transport, if the temperature and humidity values ​​in the buffer chamber 120 exceed a set threshold, the system controller controls the material layer height adjustment unit 135 to extend (i.e., move along the direction close to the bottom conveyor belt 132 of the feeding channel 131) to reduce the steaming height inside the feeding channel 131, so that a conveying speed difference is generated between the top and bottom layers of the feeding channel 131, and with the assistance of the baffle curtain 134, the speed difference is used to compensate for the material gap between the feeding channel 131 and the buffer chamber 120, thereby reducing the amount of steam entering the buffer chamber 120.

[0078] According to a preferred embodiment, the material level inside the buffer silo 120 can be independently controlled based on real-time material level information acquired by the first material level acquisition unit 121 and the second material level acquisition unit 122. Alternatively, the material level inside the buffer silo 120 can also be independently controlled based on real-time temperature and humidity information acquired by the temperature and humidity acquisition unit 123. Specifically, in this invention, the adjustment of the material level inside the buffer silo 120 based on the internal environmental information is performed in conjunction with the material level information acquired by the first material level acquisition unit 121 and / or the second material level acquisition unit 122, and / or the feeding speed of the feeding device 110. That is, the material level inside the buffer silo 120 is adjusted based on real-time material level information, temperature and humidity information, and feeding speed.

[0079] As a non-limiting example, the following illustrates different measures for adjusting the material level in the buffer bin 120 and the feed channel 131 under different operating conditions:

[0080] high high high C1 (Scraper Conveyor Speed ​​Reduction) high Low Low C2 high Low high C3 (Scraper Conveyor Speed ​​Reduction) high high Low C4 Low Low Low C5 (Scraper Conveyor Speed ​​Increase) Low high high C6 Low high Low C7 (Scraper Conveyor Speed ​​Increase) Low Low high C8

[0081] According to a preferred embodiment, as shown in C1 and C3 in the table, when the material level in the buffer bin 120 is too high, for example, exceeding the material level line corresponding to the first material level acquisition unit 121 as mentioned above, and the conveying speed of the feeding device 110, i.e. the scraper conveyor, is too high, it is necessary to reduce the discharge speed of the feeding device 110 to reduce the speed at which materials are supplied to the buffer bin 120, so as to avoid the risk of excessive material overflowing the buffer bin 120.

[0082] According to a preferred embodiment, as shown in C5 and C7 in the table, when the material level in the buffer bin 120 is too low, for example, below the material level line corresponding to the second material level acquisition unit 122 as mentioned above, and the conveying speed of the feeding device 110, i.e. the scraper conveyor, is too low, it is necessary to increase the discharge speed of the feeding device 110 to increase the speed of supplying material to the buffer bin 120, so that the buffer bin 120 stores a sufficient amount of material to reduce the possibility of steam flowing back into the feeding device 110 from the material gap. However, unlike C5, the temperature and humidity values ​​in the buffer silo 120 under C7 state are too high. Therefore, in addition to increasing the feeding speed of the feeding device 110, it is also necessary to adjust the material layer height in the feeding channel 131 (not shown in the table). That is, by controlling the material level adjustment unit 135 to block part of the rice husk material, a difference in conveying speed is created between the upper and lower layers, so that the rice husk material enters the downstream of the feeding channel 131 in a time sequence, thereby reducing the material gap between the feeding channel 131 and the buffer silo 120 that allows steam from rice husk to enter the buffer silo 120 due to insufficient material in the buffer silo 120.

[0083] According to a preferred embodiment, as shown in C1, C4, C6 and C7 in the table, since the temperature and humidity information in the buffer chamber 120 are both too high, it is necessary to adjust the steaming height in the steaming device 130 by controlling the material level adjustment unit 135, so as to reduce the material gap between the feed channel 131 and the buffer chamber 120 that allows steam to enter the buffer chamber 120, thereby reducing the amount of steam entering the buffer chamber 120.

[0084] According to a preferred embodiment, as shown in Table C1, in addition to the excessively high material level in the buffer bin 120 and the excessively high conveying speed of the feeding device 110, the temperature and humidity values ​​in the buffer bin 120 are also excessively high. Therefore, in addition to reducing the feeding speed of the feeding device 110, it is also necessary to adjust the material layer height in the feeding channel 131 (not shown in the table). That is, by controlling the extension of the material level adjustment unit 135, the high material layer in the feeding channel 131 is subjected to reverse resistance from the material level adjustment unit 135, while the low material layer in the feeding channel 131 moves along the direction of the conveyor belt 132. Based on the obstruction effect of the material level adjustment unit 135, a conveying speed difference appears between the upper and lower material layers in the feeding channel 131, thereby reducing the possibility of empty space forming between the buffer bin 120 and the feeding channel 131 through this conveying speed difference.

[0085] According to a preferred embodiment, as shown in C4 of the table, although the material level in the buffer silo 120 is high, the discharge speed of the feeding device 110 is low, so it is generally not necessary to reduce the discharge speed of the feeding device 110. However, at this time, the temperature and humidity values ​​in the buffer silo 120 are too high. Since the material level in the buffer silo 120 is already high, it means that the reason for the high temperature and humidity in the buffer silo 120 is more due to the increased material gap between the feeding channel 131 and the buffer silo 120, causing excessive steam to enter and flow back into the buffer silo 120 through the gap. Therefore, it is necessary to control the extension of the material level adjustment unit 135 so that the high material layer in the feeding channel 131 is subjected to reverse resistance from the material level adjustment unit 135. Based on the obstruction effect of the material level adjustment unit 135, a conveying speed difference appears between the upper and lower material layers of the feeding channel 131. This conveying speed difference prevents more steam from entering the buffer silo 120 through the material gap between the buffer silo 120 and the feeding channel 131.

[0086] Therefore, for example, in the operating conditions shown by control measures C1 and C4 in the table, if the first material level acquisition unit 121 used to determine the high material level gives a high material level signal during or before the material level dynamic adjustment, and at the same time the temperature and humidity acquisition unit 123 also gives a temperature and humidity signal exceeding the set threshold, then the system controller controls the material layer height adjustment unit 135 in the feeding channel 131 in the following manner: the material layer experiences greater resistance in the opposite direction to the conveying direction when moving laterally, so that more material layer bears pressure in the direction of the buffer bin 120. That is, by first obstructing the material layer located at the top or high position, the material layer at the lower position below it moves along the predetermined conveying direction of the steaming device 130, so that there is a conveying speed difference between the upper and lower material layers in the predetermined conveying direction. This allows the relationship between the conveying speed difference and the output speed of the husk of the feeding device 110 to be adjusted, so as to use the dynamic difference between the conveying speed difference and the output speed of the husk to compensate for and reduce the empty space between the buffer bin 120 and the feeding channel 131, especially between the bottom of the buffer bin 120 and the top of the feeding channel 131.

[0087] According to a preferred embodiment, since the detection of the material level switch (i.e., the first material level acquisition unit 121 and the second material level acquisition unit 122) has limitations, in order to avoid the material level sensor acquiring erroneous data and to avoid the partial emptiness of the buffer bin 120 caused by the misalignment of the material drop pile, in this invention, the material drop adjustment unit 111 can change the material conveying direction of the feeding device 110 for the buffer bin 120 based on the temperature and humidity information of the buffer bin 120, the material level information in the bin, and / or the feeding speed of the feeding device 110 to adjust the material level in the buffer bin 120.

[0088] Specifically, as shown in C4 of the table, the material level and temperature / humidity values ​​in the buffer bin 120 are too high, but the discharge speed of the feeding device 110 is low. Therefore, it is possible that the material accumulation in the buffer bin 120 is uneven, providing space for steam to flow into the empty areas inside the bin, thereby causing the temperature and humidity inside the buffer bin 120 to rise under high material level conditions. In view of this, it is necessary to change the drop point or accumulation position of the rice husk material fed into the buffer bin 120 by the feeding device 110 by adjusting the output direction of the dropping adjustment unit 111 at the top feed port of the buffer bin 120 (such as offsetting along the predetermined conveying direction of the rice husk steaming device 130), thereby changing the material accumulation state in the buffer bin 120 to fill the local empty areas inside the buffer bin 120.

[0089] Specifically, the adjustment of the conveying direction of the material discharge adjustment unit 111 can be achieved through manual operation settings or by the system controller based on predetermined threshold programming and machine learning results. Specifically, at a constant feeder conveying speed, the material discharge adjustment unit 111 is offset by a predetermined angle, and the changes in material level and temperature / humidity within the buffer hopper 120 are recorded. The output direction of the material discharge adjustment unit 111 is then adjusted based on these changes. For example, if the offset of the material discharge adjustment unit 111 at a previous moment or state causes a decrease in temperature / humidity within the hopper and a decrease in material level (e.g., if the material level sensor generates erroneous data, material fills the gaps on both sides of the high material level, thus causing the overall material level to decrease), then feeding can be maintained in that output direction. Furthermore, as the feeding process of the feeder 110 continues, the changes in material level and temperature / humidity in the buffer hopper 120 are continuously recorded to control the material discharge adjustment unit 111 to continue offsetting in the output direction or the opposite direction. Specifically, based on the results of machine learning, a control model for adjusting the material discharge adjustment unit 111 can be generated. By importing the corresponding material level, temperature and humidity information and the feeding speed of the feeder into the control model, the output direction of the material discharge adjustment unit 111 can be used as output information. Thus, the material accumulation state in the buffer bin 120 can be adjusted based on the change in the output direction of the material discharge adjustment unit 111, so as to reduce the steam entering the feeding device 100 through the material accumulation gap.

[0090] It should be understood that the working conditions shown in the table above only list some possible situations in the rice bran steaming process. The inventor has not exhaustively listed all possible working conditions. Therefore, the above situations should not be regarded as limitations on the specific application scenarios or protection scope of the present invention. In addition, it is worth noting that in order to reduce or prevent steam from the rice bran steaming machine from entering the feeding machine, a buffer chamber 120 for buffering and adjustment is provided between the material passages of the two. For this purpose, the preferred embodiment of the present invention is to correlate the temperature and humidity information, material level information and feeding speed of the feeding machine in the buffer chamber 120 with each other as the basis for adjustment to reduce steam backflow (or "steam short circuit"). That is, while adjusting the movement of the material level adjustment unit 135 to slow down the feeding speed of the feeding channel 131 based on the temperature and humidity information in the buffer chamber 120, and thus adjusting the material level in the buffer chamber 120, the feeding speed of the feeding machine should be adjusted simultaneously according to the real-time material level in the buffer chamber 120. In this way, the feeding speed of the feeding machine should be adjusted as little as possible through this correlated adjustment.

[0091] Optionally, the present invention may also include an image acquisition device for acquiring images from the observation window 124. The system controller can determine the start and stop of the steaming device 130 based on the images acquired by the image acquisition device. Specifically, when the system controller determines, based on the images acquired by the image acquisition device, that there is material accumulating at the outlet of the buffer bin 120, the system controller can control the material layer height adjustment unit 135 to retract the free end of the contact conveyor belt 132 and control the conveyor belt 132 to start so that the steaming device 130 can operate. On the other hand, when the system controller determines, based on the images acquired by the image acquisition device, that there is no material accumulating at the outlet of the buffer bin 120, the system controller can control the material layer height adjustment unit 135 to move its free end to contact the conveyor belt 132 to prevent upstream material from continuing to enter the downstream of the feed channel 131. Further, after all the material has been discharged from the outlet of the steaming device 130, the system controller controls the conveyor belt 132 to stop operating so that the steaming device 130 can stop.
