Description

Technical Field

[0001] This invention relates to the technical field of equipment and processes for producing wood, and particularly to a wood production system and method. Background Technology

[0002] Horse racing is a very popular sport with high commercial value, and the health of the horses is key to their success.

[0003] Racehorses usually stay in stables, where the floor is covered with stable bedding, which can be made of small pieces of wood. The small pieces of wood can absorb horse urine, and by changing the stable bedding, the stable is kept dry and clean.

[0004] Stable bedding is preferably wood shavings, which can absorb moisture, keep the ground dry, and prevent racehorses from slipping.

[0005] However, existing wood shavings are mostly used in furniture production, for example, as a raw material for high-pressure boards, which is difficult to meet the special needs of horse racing. Summary of the Invention

[0006] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a wood production system capable of producing wood shavings that meet the needs of racehorses, satisfying the high-quality requirements of racehorses for stable bedding.

[0007] The present invention also proposes a wood production method applicable to the aforementioned wood production system.

[0008] A wood production system according to a first aspect of the present invention: the wood production system includes a wood shaving module, a heat treatment module, and a post-treatment module; the wood shaving module includes wood shaving equipment; the heat treatment module includes a steam heating device; and the post-treatment module includes a sterilization and disinfection device; the sterilization and disinfection device includes a sterilization and disinfection screening box, the sterilization and disinfection screening box including a first box body; a first feed inlet is provided on one side of the top of the first box body, and a first discharge outlet is provided on the other side of the top of the first box body, forming a first channel between the first feed inlet and the first discharge outlet, and a sterilizer is provided in the first channel; a first blower is provided on the side wall of the first box body, the first blower being located at the bottom of the first feed inlet, and the first blower being used to blow wood shavings so that the wood shavings pass through the first channel.

[0010] This invention, by incorporating a heat treatment module, can heat wood shavings and alter their moisture content, such as reducing the moisture content to dry them. This allows the shavings to absorb moisture from the stable, keeping the stable dry and reducing bacterial growth.

[0011] This invention, by incorporating a post-processing module, can sterilize and disinfect wood shavings, reducing or even eliminating the introduction of bacteria from wood shavings and preventing them from affecting the health of racehorses.

[0012] This invention incorporates a sterilization and disinfection screening box, using a first blower to blow wood shavings from the first feed inlet to the first discharge outlet. On one hand, gravity allows fine impurities within the wood shavings to settle, separating them from the shavings and improving their quality. This prevents racehorses from inhaling fine impurities that could affect their bodily functions. On the other hand, it allows the wood shavings to spread out fully, facilitating the penetration and permeation of the disinfection light or gas generated by the sterilizer in the first channel. This ensures even and thorough disinfection of the wood shavings, preventing insufficiently disinfected shavings from reaching users and guaranteeing the health of the racehorses.

[0041] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation, connection, and linkage" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0042] A timber production system and timber production method according to an embodiment of the present invention are described below with reference to the accompanying drawings.

[0043] Reference Figures 1 to 16 The present invention aims to provide a timber production system, while referring to Figure 17 The present invention also provides an embodiment of a timber production method, wherein the timber production method of this embodiment is applied to... Figures 1 to 16 The timber production system.

[0044] The present invention provides a wood production system and method that can produce wood shavings suitable for stable bedding to meet the high-quality requirements of racehorses for stable bedding.

[0045] Reference Figure 1 The wood production system of the present invention includes a wood shaving module, a heat treatment module and a post-treatment module. The wood shaving module is used to process wood into wood shavings, the heat treatment module is used to heat the wood shavings to change the moisture content of the wood shavings and kill bacteria at the same time using high temperature, and the post-treatment module is used to further screen, disinfect and package the wood shavings.

[0046] Reference Figures 2 to 4 The wood shaving module mainly includes a cutting device 100 and a wood shaving device 140.

[0047] Specifically, the cutting device 100 can be omitted when the incoming wood material meets the requirements for wood shavings. However, the length of the incoming wood material is generally much longer than that of the wood shaving device 140. Therefore, the cutting device 100 is required to cut the wood so that the length of the wood meets the requirements of the wood shaving device 140.

[0048] Reference Figure 3 In some specific embodiments of the present invention, the cutting device 100 may include a conveyor chain 110 arranged along the length direction of the wood, a saw blade 120 that moves in a direction perpendicular to the conveyor chain 110 to cut the wood, and a length plate 130 for abutting the end of the wood to limit the cutting length, the length plate 130 being rotatable to abut the end of the wood and to release the abutment.

[0049] Therefore, by placing the timber on the conveyor chain 110 and moving the conveyor chain 110, the timber can be moved along its length. The conveyor chain 110 does not include the front conveyor chain 110 and the rear conveyor chain 110. The saw blade 120 is allowed to pass between the front conveyor chain 110 and the rear conveyor chain 110, so that the saw blade 120 can cut the timber without affecting the conveying of the timber.

[0050] The length-fixing plate 130 can be set to abut the end of the wood to confirm the position of the wood movement and cut the wood to a fixed length.

[0051] In some specific embodiments of the present invention, the length plate 130 may be connected to a cylinder, and the length plate 130 may be rotatably mounted.

[0052] Therefore, the cylinder can drive the fixed length plate 130 to rotate. When the fixed length plate 130 is on the path of the wood, the wood touches the fixed length plate 130, and the distance the wood has moved can be determined, thereby determining the cutting length of the wood. When the fixed length plate 130 rotates away from the path of the wood, the fixed length plate 130 no longer obstructs the movement of the wood and does not affect the conveyor chain 110 from conveying the wood.

[0053] In some specific embodiments of the present invention, the fixed-length board 130 may be equipped with a pressure sensor or a micro-touch switch. When the wood touches the pressure sensor or the micro-touch switch, the conveyor chain 110 is controlled to stop moving.

[0054] Reference Figure 4 For the wood shaving device 140, which is used to shave wood into wood shavings, the wood shaving device 140 includes a translating box 150 for accommodating wood, the top of the translating box 150 being open to load wood, and the bottom of the translating box 150 being open to expose wood.

[0055] In addition, the wood shaving device 140 also includes a wood shaving roller 160 located at the bottom of the translation box 150. The wood shaving roller 160 is equipped with a wood shaving blade 170. The wood shaving roller 160 rotates to drive the wood shaving blade 170 to plane the wood inside the translation box 150 and produce wood shavings.

[0056] That is, the wood is put into the translation box 150, and the wood relies on its own weight to make the bottom of the wood touch the shaving blade 170 on the shaving roller 160. Then, the translation box 150 moves horizontally, the shaving roller 160 rotates, and the shaving blade 170 continuously shaves the wood to produce wood shavings. The wood shavings fall into the conveyor belt at the bottom of the shaving device 140, and the conveyor belt transports the wood shavings to the next process.

[0057] In some specific embodiments of the present invention, a flipping device and a lifting device may be provided between the cutting device 100 and the shaving device 140. The flipping device causes the wood to roll onto the lifting device, and the lifting device gradually lifts the wood and puts the wood into the translation box 150 one by one.

[0058] In some specific embodiments of the present invention, the planing device may include a wood pressing mechanism that presses the wood in the translation box 150, so that the pressure between the wood and the planing blade 170 is less varied, thereby producing shavings of uniform thickness, which is adapted to the characteristic that the weight of the wood gradually decreases during the planing process.

[0059] Reference Figures 5 to 6 Since wood shavings are formed by planing wood, they contain many impurities, such as dirt, bark, and nails. Coarse screening equipment can remove these impurities to avoid affecting the processing steps, while also reducing energy consumption and lowering production costs.

[0060] The coarse screening equipment mainly includes a coarse screening box 180, which includes a second box body; a second feed inlet 190 is provided on one side of the top of the second box body, and a second discharge outlet 200 is provided on the other side of the top of the second box body, forming a second channel 210 between the second feed inlet 190 and the second discharge outlet 200.

[0061] In addition, a second blower 240 is provided on the side wall of the second housing. The second blower 240 is located at the bottom of the second feed inlet 190 and is used to blow wood shavings to the second discharge outlet 200.

[0062] That is, when the wood shavings enter the second feed inlet 190, they will fall naturally due to their own weight. The second blower 240 will generate a positive pressure airflow, which will cause the wood shavings to flow forward and pass through the second channel 210. Since the soil, bark, and nails have a small surface area or are heavy, they will fall and separate from the wood shavings, making the wood shavings relatively pure.

[0063] In some specific embodiments of the present invention, the second discharge port 200 may be connected to or communicated with a suction fan 250. The suction fan 250 is used to suck up wood shavings to the second discharge port 200. Therefore, the suction fan 250 generates a negative pressure airflow, which promotes the flow of wood shavings with the airflow, reduces the airflow resistance, and facilitates the passage of wood shavings through the second discharge port 200.

[0064] In some specific embodiments of the present invention, a conveyor belt may be provided between the coarse sieve box 180 and the planing device to lift the wood shavings and facilitate their entry into the second feed inlet 190.

[0065] In some specific embodiments of the present invention, the number of second blowers 240 can be three, and the three second blowers 240 are arranged in a vertical sequence to increase the blowing area, which makes it easier to gradually and deeply disperse the falling wood shavings and facilitate the separation of impurities.

[0066] In some specific embodiments of the present invention, the bottom wall of the second housing may be provided with a second inclined wall 220, the lower end of the second inclined wall 220 being located near the bottom of the second blower 240, and a second impurity outlet 230 being formed between the bottom end of the second inclined wall 220 and the side wall of the second housing, which facilitates the collection and falling of impurities.

[0067] Below the second impurity outlet 230, a second impurity conveying mechanism can be installed to facilitate the discharge of impurities, prevent impurities from accumulating on site, and achieve automated cleaning, saving labor.

[0068] In some specific embodiments of the present invention, a second conveyor belt may be arranged on the second inclined wall 220, or the second inclined wall 220 may be formed by the second conveyor belt, so as to facilitate the cleaning of shavings or residual impurities on the second inclined wall 220 and meet the needs of daily maintenance.

[0069] In some specific embodiments of the present invention, a plurality of second baffles may be provided on the second conveyor belt, and a second storage space may be formed between two adjacent second baffles to prevent normal wood shavings from being discharged from the second impurity outlet 230 by mistake. Therefore, during maintenance operations, the wood shavings on the second inclined wall 220 can be discharged and screened and put into the next process, reducing material waste.

[0070] Reference Figures 7 to 8 The wood used for wood shavings is mostly freshly felled logs. The logs vary in moisture content, and freshly shavings generally contain too much moisture, making them unsuitable for drying. Therefore, further drying is necessary. However, wood shavings are very thin, and high drying temperatures can easily cause fires, while low temperatures reduce drying efficiency. Therefore, a drying process is employed... Figures 7 to 8 Steam heating equipment.

[0071] The steam heating equipment includes a steam production device 260, a feed shell 270, and a heat treatment tube 300. The feed shell 270 is provided with a steam inlet connected to the steam production device 260, a feeding port 280 for entering wood shavings, and a material outlet 290 for connecting to the heat treatment tube 300. The heat treatment tube 300 is horizontally arranged and can rotate around its own axis. One end of the heat treatment tube 300 receives steam and wood shavings from the feed shell 270, and the other end of the heat treatment tube 300 is used to discharge wood shavings.

[0072] Therefore, the steam production device 260 uses fuel or electricity to heat water into steam in a boiler. The high-temperature steam is then used to heat the wood shavings. The steam can generate a high temperature, such as above 600 degrees Celsius. The high temperature will remove the moisture from the wood shavings, forming high-temperature saturated steam. The high-temperature saturated steam is then used to form an atmosphere that isolates the wood shavings from oxygen, preventing combustion and improving the safety of the heat treatment.

[0073] Because of the feed shell 270, which has a steam inlet, a feeding port 280 and a passing port 290, it is convenient to mix steam and wood shavings. At the same time, it is convenient for steam and wood shavings to enter the heat treatment tube 300 together after mixing, so as to achieve continuous production and improve efficiency.

[0074] In some specific embodiments of the present invention, the inner surface of the heat treatment tube 300 may be provided with spiral ribs to facilitate the discharge of wood shavings to the other end of the heat treatment tube 300.

[0075] In some specific embodiments of the present invention, the outer surface of the heat treatment tube 300 may be provided with a toothed ring, so that the motor can drive the rotation through the gear.

[0076] In some specific embodiments of the present invention, the outer surface of the heat treatment tube 300 may be provided with an annular groove, and rollers may be provided on the left and right sides of the groove to reduce the rotational resistance of the heat treatment tube 300.

[0077] In some specific embodiments of the present invention, the steam heating device can generate steam at a temperature higher than 600 degrees Celsius. The steam at a temperature higher than 600 degrees Celsius is used to heat the wood shavings, thereby improving the drying efficiency. At the same time, it can also kill most of the bacteria in the wood shavings, achieving the dual effects of sterilization and drying.

[0078] Reference Figure 8 and Figure 9 The dried wood shavings will produce fine debris. When racehorses inhale these fine debris, it will affect their lung health and may affect their race performance. Therefore, the post-processing module is also equipped with a debris removal device, which includes a dust collection device 310. The dust collection device 310 can remove fine debris, that is, remove dust.

[0079] Reference Figure 8 and Figure 10 The dust collection device 310 includes a volute installed at the end of the heat treatment tube 300. The volute uses centrifugal principle to remove dust. At the same time, the volute installed at the end of the heat treatment tube 300 can also use steam airflow to accelerate the flow of wood shavings, making full use of the original kinetic energy of the wood shavings and saving energy consumption.

[0080] In some specific embodiments of the present invention, the bottom of the volute can be provided with a discharge port to facilitate the discharge of the required wood shavings, while the top of the volute can be provided with a dust outlet. The dust outlet is connected to an external spraying device or electrostatic dust removal device through a pipe to collect the dust.

[0081] Reference Figure 9 and Figure 11 The impurity removal equipment also includes a screening device 330, which uses a screen to sieve wood shavings.

[0082] Specifically, the screen is in the form of a drum, that is, a drum screen 340 or a drum screen 340 mesh. The drum screen 340 is driven to rotate by a motor. The drum screen 340 is placed at an angle. The high point of the drum screen 340 allows wood shavings to enter, while the low point of the drum screen 340 is used to discharge the screened wood shavings. The bottom of the drum is used to discharge fine wood shavings that are larger than dust particles but smaller than the required wood shavings.

[0083] In some specific embodiments of the present invention, a conveyor belt can be provided between the screening device 330 and the dust collection device 310 to lift the wood shavings at a lower position to a higher position to meet the feeding requirements of the screening device 330. At the same time, a large space is reserved at the bottom of the screening device 330 to facilitate the placement of a movable waste bin, facilitate forklift transportation, and reduce the floor space occupied.

[0084] Reference Figure 9 and Figure 12 The impurity removal equipment also includes a magnetic suction device 350, which uses magnetic force to remove metal from the wood shavings, preventing metal impurities from flowing out. Metal impurities are mainly iron-containing materials, such as iron filings and nails. Iron filings and nails are sharp and can easily injure racehorses, so they need to be removed.

[0085] The magnetic attraction device 350 mainly includes an inclined conveyor belt and a magnetic attraction mechanism set above the inclined conveyor belt. The magnetic attraction mechanism preferably uses magnets 360, such as permanent magnets 360, to avoid introducing current, reduce energy consumption, and reduce fires caused by short circuits.

[0086] In use, the inclined conveyor belt transports wood shavings upwards. When the wood shavings pass through the magnetic attraction mechanism, iron filings and nails are attracted and separated from the wood shavings, resulting in cleaner and larger wood shavings.

[0087] Reference Figures 13 to 14 In order to further reduce the bacterial content in wood shavings and reduce the harm caused by bacterial growth, and in order to meet the requirements of import and export safety certification, the post-processing module includes sterilization and disinfection equipment.

[0088] Specifically, the sterilization and disinfection equipment mainly includes the sterilization and disinfection screening box 370.

[0089] The sterilization and disinfection screening box 370 includes a first box body; a first feed inlet 380 is provided on one side of the top of the first box body, and a first discharge outlet 390 is provided on the other side of the top of the first box body. A first channel 400 is formed between the first feed inlet 380 and the first discharge outlet 390. A sterilizer 440 is provided in the first channel 400. A first blower 430 is provided on the side wall of the first box body. The first blower 430 is located at the bottom of the first feed inlet 380. The first blower 430 is used to blow wood shavings so that the wood shavings pass through the first channel 400.

[0090] In summary, this embodiment, by setting a wood shaving module, can shave wood into wood shavings to meet the needs of stable bedding.

[0091] This embodiment uses a heat treatment module to heat the wood shavings, changing their moisture content, such as reducing the moisture content to dry them. This allows the shavings to absorb moisture from the stable, keeping it dry and reducing bacterial growth.

[0092] This embodiment, by setting up a post-processing module, can sterilize and disinfect wood shavings, reducing or even eliminating the introduction of bacteria from wood shavings and preventing them from affecting the health of racehorses.

[0093] In this embodiment, a sterilization and disinfection screening box 370 is set up, and a first blower 430 is used to blow wood shavings from the first feed inlet 380 to the first discharge outlet 390. On the one hand, gravity can be used to make the fine impurities in the wood shavings settle and separate them from the wood shavings, thereby improving the quality of the wood shavings and preventing the racehorses from inhaling fine impurities that could affect their physical functions. On the other hand, the wood shavings can be fully dispersed, allowing the disinfection light or disinfection gas generated by the sterilizer 440 in the first channel 400 to fully penetrate and permeate, disinfecting the wood shavings evenly and meticulously, preventing insufficiently disinfected wood shavings from flowing to the user, and ensuring the health of the racehorses.

[0094] The wood production system of this embodiment can produce high-quality wood shavings for use as stable bedding for racing horses. At the same time, the wood shavings produced by this invention can also be used as bedding for other livestock, or for other purposes, to meet the requirements of low moisture, low dust, and easy water absorption.

[0095] In some specific embodiments of the present invention, the number of sterilizers 440 can be multiple, and the multiple sterilizers 440 are arranged along the extension direction of the first channel 400, thereby extending the sterilization path, extending the sterilization time, and achieving deeper and more thorough sterilization.

[0096] In some specific embodiments of the present invention, the sterilizer 440 can be a sterilization lamp or an ozone generator to meet the needs of light sterilization and ozone sterilization.

[0097] In some specific embodiments of the present invention, the number of first blowers 430 can be multiple, and the multiple first blowers 430 are arranged in the vertical direction, which can increase the blowing area, facilitate the gradual and deep dispersal of falling wood shavings, facilitate the separation of impurities, and at the same time, make the airflow in various positions in the first box flow evenly, avoiding local deposition of wood shavings.

[0098] In some specific embodiments of the present invention, the bottom of the first box body may be provided with a first inclined wall 410, the bottom end of the first inclined wall 410 is located at the bottom of the first blower (430) and forms a first impurity outlet 420, and the top end of the first inclined wall 410 is located near the first discharge port 390 to facilitate the collection and falling of impurities.

[0099] Below the first impurity outlet 420, a first impurity conveying mechanism can be installed to facilitate the discharge of impurities, prevent impurities from accumulating on site, and achieve automated cleaning, saving labor.

[0100] In some specific embodiments of the present invention, a first conveyor belt may be provided at the bottom of the first housing. The first conveyor belt is inclined and its bottom end is located at the bottom of the first blower 430 and is used to form a first impurity outlet 420. The top end of the first conveyor belt is provided near the first discharge port 390. The first conveyor belt is provided with a plurality of first baffles, which are used to limit the shavings so that the shavings move along the first conveyor belt.

[0101] In some specific embodiments of the present invention, a temporary storage device may be provided at the bottom of the outer side of the first discharge port 390. The temporary storage device is used to store sterilized wood shavings. The temporary storage device may include a temporary storage bin and a temporary storage conveyor belt disposed at the bottom of the temporary storage bin. When the subsequent process requires wood shavings, the temporary storage conveyor belt transports them to the subsequent process.

[0102] Reference Figure 15 and Figure 16 The post-processing module includes a packaging device located after the sterilization and disinfection equipment. The packaging device includes a weighing device and a compression packaging device 510. The weighing device is used to weigh and provide a quantitative amount of wood shavings, and the compression packaging device 510 is used to press a quantitative amount of wood shavings into a packaging bag under a set pressure condition.

[0103] In some specific embodiments of the present invention, the weighing device may include a weighing conveyor belt, a roller group supporting the weighing conveyor belt, a weighing frame for mounting the roller group, and a plurality of first pressure sensors supporting the weighing frame, wherein the plurality of first pressure sensors are disposed at the four corners of the weighing frame.

[0104] In use, the weight of the wood shavings can be calculated by measuring the pressure change of the first pressure sensor, thereby controlling the quality of the wood shavings to be packaged to meet shipping requirements.

[0105] In particular, strictly controlling the weight of wood shavings can prevent the wood shavings from becoming too bulky when compressed under constant pressure, thus making them difficult to seal in bags and reducing the difficulty of stacking.

[0106] Reference Figure 16 In some specific embodiments of the present invention, the compression packaging device 510 may include a discharge bag tube 450, a support plate 460 located on the material receiving side of the discharge bag tube 450, and a side limiting plate 470. The discharge bag tube 450 is used to package the bags.

[0107] In addition, the compression and packaging device 510 includes a pressing mechanism 480 located above the support plate 460, a side pressing mechanism opposite to the side limiting plate 470, a pushing mechanism 490 located on the side of the support plate 460 away from the discharge bag tube 450, and a liftable blocking mechanism 500 located on the side of the support plate 460 near the discharge bag tube 450. The pressing mechanism 480, the side pressing mechanism, and the pushing mechanism 490 are all equipped with a second pressure sensor. The second pressure sensor is used to detect the compression force on the wood shavings and control the compression force on the wood shavings within a set range.

[0108] It is easy to understand that this embodiment can form a space for compressing wood shavings by setting a support plate 460 and a side limiting plate 470. The material pressing mechanism 480 located above the support plate 460, the side pressing mechanism opposite to the side limiting plate 470, the material pushing mechanism 490 located on the side of the support plate 460 away from the discharge bag tube 450, and the liftable material blocking mechanism 500 located on the side of the support plate 460 near the discharge bag tube 450 also facilitate the compression of wood shavings from above, the side, and the front and back directions to form the required stable bedding blocks.

[0109] The system is equipped with a second pressure sensor to control the compression of the wood shavings, allowing them to be packaged at a set density. This makes it easier to break down the shavings for use and spread them in the stable, reducing the workload for the grooms.

[0110] In use, the material blocking mechanism 500 descends to block the discharge bag tube 450. Then, the side pressing mechanism, the pressing mechanism 480, and the pushing mechanism 490 operate, causing the wood shavings to move onto the support plate 460 and approach the side limiting plate 470, compressing the wood shavings into blocks. At the same time, based on the detection data of the second pressure sensor, when the pressure reaches the set range, the side pressing mechanism, the pressing mechanism 480, and the pushing mechanism 490 stop operating and remain in place to prevent the wood shavings from being further compressed.

[0111] Then, the material blocking mechanism 500 rises, and the material pushing mechanism 490 pushes out the wood shavings. Since the outer side of the discharge bag tube 450 is fitted with a packaging bag, the wood shavings can be easily put into the packaging bag. Then, sealing and stacking operations can be carried out to meet transportation needs.

[0112] In some specific embodiments of the present invention, the pressing mechanism 480, the side pressing mechanism and the pushing mechanism 490 can be implemented by hydraulic cylinders, which make the pressure easy to control and durable, suitable for mass production. At the same time, other forms of linear power mechanisms can be used to replace the hydraulic cylinders without restriction.

[0113] In some specific embodiments of the present invention, the tops of the first and second boxes can be open, and plastic mesh can be used to cover them for easy maintenance and to facilitate airflow so as to spread the wood shavings.

[0114] Reference Figure 17 The present invention provides an embodiment of a wood production method applied to the above-mentioned wood production system.

[0115] The wood production method includes wood cutting step S1, wood planing step S2, wood shaving coarse screening step S3, wood shaving heat treatment step S4, wood shaving dust removal step S5, wood shaving sorting step S6, wood shaving gold removal step S7, sterilization and disinfection step S8, and wood shaving packaging step S9.

[0116] In the wood cutting step S1, the long strip of wood is cut to a fixed length to form a fixed-length piece of wood. In the wood planing step S2, the wood planing step S2 plans the fixed length of wood into wood shavings. In the coarse shavings screening step S3, the coarse shavings screening step S3 uses airflow to transport the shavings and uses the gravity of the impurities to separate the impurities in the shavings. In the wood shavings heat treatment step S4, the wood shavings are heated with high-temperature steam. In the wood shavings dust removal step S5, the dust removal step S5 uses the centrifugal principle to remove dust, which is generated from the heated wood shavings. In the wood shavings screening step S6, a sieve is used to screen the dust-free wood shavings. In the metal removal step S7, the metal is removed by magnetic force. In the sterilization and disinfection step S8, the sterilization and disinfection step S8 uses airflow to transport wood shavings. During the airflow transport process, sterilizing light and / or sterilizing gas are used to sterilize and disinfect the wood shavings. In the wood shavings packaging step S9, the wood shavings are quantitatively separated, and the wood shavings are compressed with a set pressure and packed into packaging bags.

[0117] In some specific embodiments of the present invention, in the coarse shavings screening step S3, airflow is used to transport the shavings, including: using positive pressure airflow to blow the shavings while using negative pressure airflow to suck the shavings.

[0118] In some specific embodiments of the present invention, in the wood shavings heat treatment step S4, high-temperature steam is used to heat the wood shavings, including: the high-temperature steam and the wood shavings are mixed and move in the same direction.

[0119] In some specific embodiments of the present invention, the shavings packaging step, which involves compressing the shavings with a set pressure and packing them into a packaging bag, includes: compressing the shavings to a set volume with a set pressure, and then packing the shavings into a packaging bag.
