Description

Technical Field

[0001] The present invention relates to the technical field of fermentation equipment, and in particular to an anaerobic fermentation device and method for bait processing. Background Art

[0002] Currently, most traditional baits are made of earthworms or flour, which are very inconvenient during production or when hooking. Therefore, fishermen tend to use artificial baits. During the production process of artificial baits, anaerobic fermentation is usually required. When the existing baits are anaerobically fermented, the bacteria in the baits can only perform anaerobic fermentation in a suitable environment. Since the baits are stacked together, the heating or water addition devices work from a fixed position, and it cannot be ensured that the baits in each position are in a suitable environment, which seriously affects the normal anaerobic fermentation of the baits and reduces the quality of anaerobic fermentation of the baits.

[0003] The prior art CN209098653U discloses an anaerobic fermentation device for environmentally friendly bait processing. By providing a trachea on the main body, the trachea is set in an L shape, and the air inlet end of the trachea is fixedly connected to a fan and a water storage tank. Through the action of the fan, the hot air generated by the heating wire can be effectively introduced into the trachea. Through the action of the trachea, the hot air and water mist can be mixed and then evenly dispersed into the main body, so that all the baits can be in a suitable environment, ensuring that all the baits can be anaerobically fermented quickly and completely, and improving the quality of anaerobic fermentation of the baits.

[0004] However, the above anaerobic fermentation device spreads the bait on the fermentation plate, resulting in insufficient fermentation of the part of the bait in contact with the fermentation plate at the bottom during anaerobic fermentation of the bait on the fermentation plate, thus reducing the fermentation effect of the bait. Summary of the Invention

[0005] The purpose of the present invention is to provide an anaerobic fermentation device and method for bait processing, which solves the technical problem that the existing anaerobic fermentation device spreads the bait on the fermentation plate, resulting in insufficient fermentation of the part of the bait in contact with the fermentation plate at the bottom during anaerobic fermentation of the bait on the fermentation plate, thus reducing the fermentation effect of the bait.

[0006] To achieve the above object, the present invention provides an anaerobic fermentation device for bait processing, which includes a fermentation tank, and also includes a partition board, a driving mechanism, a support plate, a fixing plate, a fermentation plate, a cover plate, an air inlet pipe, a water inlet pipe, a heating plate, a fan, a mixing mechanism and a jet nozzle. The partition board is arranged inside the fermentation tank, dividing the internal space of the fermentation tank into upper and lower chambers. The driving mechanism and the support plate are both located in the upper chamber of the fermentation tank. The driving mechanism is used to drive the support plate to move up and down. On both the left and right sides of the support plate, there are provided the fixing plates. Between the two fixing plates, a plurality of the fermentation plates are rotatably arranged. On the two fixing plates, there is jointly provided a cover plate, and the cover plate is slidably connected to the fermentation tank. The air inlet pipe and the water inlet pipe are both communicated with the lower chamber of the fermentation tank, and the air inlet pipe is located above the water inlet pipe. The heating plate is arranged at the bottom of the lower chamber of the fermentation tank. The fan is communicated with the partition board and is located below the partition board. The mixing mechanism is used to mix the inert gas and the mist evenly. The jet nozzle is communicated with the partition board and is located on the partition board.

[0007] Among them, the driving mechanism includes a driving part and a buffer spring. The output end of the driving part is connected to the support plate. The driving part is arranged on the partition board. The buffer spring is arranged between the partition board and the support plate.

[0008] Among them, the rotation of each fermentation plate between the two fixing plates is realized by being driven by a rotation motor.

[0009] Among them, the mixing mechanism includes a transmission part, a rotating column and stirring blades. The transmission part is used to drive the stirring blades to move horizontally in the rotating column and rotate in the lower chamber of the fermentation tank. The rotating column penetrates the fermentation tank. The stirring blades are slidably arranged in the rotating column.

[0010] Among them, the transmission part includes a transmission motor, a first gear and a second gear. The transmission motor is arranged outside the fermentation tank on one side close to the rotating column. The first gear is connected to the output shaft of the transmission motor and is located on the side of the transmission motor away from the fermentation tank. The second gear meshes with the first gear and is arranged outside the rotating column.

[0011] Among them, the transmission part further includes a support seat, a stirring motor and a screw rod. The support seat is arranged outside the fermentation tank on one side close to the second gear. The stirring motor is arranged on the support seat. The screw rod is connected to the output end of the stirring motor and is movably connected to the stirring blades and is located inside the rotating column.

[0012] The present invention also provides an anaerobic fermentation method for bait processing, including the following steps: Start the driving part, and drive the support plate to move up and down in the upper chamber of the fermentation box through the driving part, drive the fixing plate to move up and down in the upper chamber, so as to drive the fermentation plate and the cover plate to move up and down in the upper chamber; When both the fermentation plate and the cover plate are removed from the upper chamber, evenly spread the fish bait on the fermentation plate, and then move the fermentation plate and the cover plate downward until the cover plate completely closes the upper chamber; Introduce inert gas into the inlet pipe, and then introduce water mist into the inlet water pipe, start the heating plate, and let the heating plate heat the inert gas and the water mist; While heating the inert gas and the water mist, let the stirring blades move horizontally and rotate in the lower chamber of the fermentation box to achieve uniform mixing of the inert gas and the water mist; After heating, start the fan. Under the suction of the fan, it is inhaled into the jet nozzle and then ejected from the jet nozzle to provide an anaerobic fermentation environment for the fish bait on the fermentation plate; After fermenting the fish bait for a period of time, first start the rotating motor at the bottom layer, drive the fermentation plate at the bottom layer to rotate through the rotating motor, and let the fish bait on the fermentation plate flip 180 degrees and fall onto the support plate; Then start the rotating motor of the adjacent upper layer, drive the fermentation plate of the adjacent upper layer to rotate, and let the fish bait on the fermentation plate of the adjacent upper layer flip 180 degrees and fall onto the fermentation plate of the adjacent lower layer on the next side; Repeat the operation of the previous step to let the fish bait on the upper layer all fall onto the fermentation plate of the adjacent lower layer, so as to fully ferment the fish bait on all the fermentation plates.

[0013] An anaerobic fermentation device and method for processing fish bait according to the present invention divide the internal space of the fermentation tank into upper and lower chambers by the partition plate. Then, inert gas and water mist are respectively introduced into the lower chamber of the fermentation tank through the inlet pipe and the inlet water pipe. The inert gas and water mist are heated by the heating plate, and after heating, the inert gas and water mist are transmitted into the upper chamber of the fermentation tank through the fan, so as to provide an anaerobic fermentation environment for the fish bait spread on the fermentation plate in the upper chamber of the fermentation tank. After the fish bait ferments for a period of time, all the fermentation plates rotate in sequence within the two fixing plates, so that the fish bait on the fermentation plates falls onto the support plate and the fermentation plates in sequence, realizing the turning of the fish bait, so that the part of the fish bait in contact with the fermentation plate at the bottom can also be fully fermented, thereby improving the fermentation effect of the fish bait, and solving the technical problem that the existing anaerobic fermentation device spreads the fish bait on the fermentation plate, resulting in insufficient fermentation of the part of the fish bait in contact with the fermentation plate at the bottom during anaerobic fermentation of the fish bait on the fermentation plate, thus reducing the fermentation effect of the fish bait.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] Embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0021] First Embodiment: Please refer to Figures 1 to 3 , the present invention provides an anaerobic fermentation device for bait processing, including a fermentation tank 101, a partition plate 102, a driving mechanism, a support plate 103, a fixing plate 104, a fermentation plate 105, a cover plate 106, an air inlet pipe 107, a water inlet pipe 108, a heating plate 109, a fan 110, a mixing mechanism, and a jet nozzle 111. Among them, the partition plate 102 is arranged inside the fermentation tank 101, dividing the internal space of the fermentation tank 101 into upper and lower chambers. The driving mechanism and the support plate 103 are both located in the upper chamber of the fermentation tank 101, and the driving mechanism is used to drive the support plate 103 to move up and down; on both the left and right sides of the support plate 103, there are provided the fixing plates 104, and several fermentation plates 105 are rotatably arranged between the two fixing plates 104. The rotation of each fermentation plate 105 between the two fixing plates 104 is realized by driving of a rotation motor 122. One of the two fixing plates 104 is evenly provided with rotation motors 122 on the outside, and the output shaft of the rotation motor 122 penetrates the fixing plate 104. The fermentation plate 105 is arranged outside the output shaft of the rotation motor 122 at the corresponding position. By starting the rotation motor 122, the rotation of the output shaft of the rotation motor 122 drives the fermentation plate 105 to rotate along the axis of the output shaft of the rotation motor 122 between the two fixing plates 104, so as to realize the flipping of the fermentation plate 105. The driving motor is a stepping motor, and the step angle of the next driving motor differs from that of the adjacent previous driving motor by 180 degrees. After the next driving motor drives the fermentation plate 105 at the corresponding position to rotate 180 degrees, the adjacent previous driving motor drives the fermentation plate 105 at the corresponding position to start rotating.

[0022] A cover plate 106 is commonly provided on the two fixing plates 104, and the cover plate 106 is slidably connected to the fermentation tank 101. Specifically, both the left and right sides of the fermentation tank 101 have sliding grooves, and both the left and right sides of the cover plate 106 have protrusions. The protrusions of the cover plate 106 cooperate with the sliding grooves of the fermentation tank 101, so that the protrusions of the cover plate 106 can slide up and down in the sliding grooves of the fermentation tank 101.

[0023] The intake pipe 107 and the water inlet pipe 108 are both communicated with the lower chamber of the fermentation tank 101, and the intake pipe 107 is located above the water inlet pipe 108; the heating plate 109 is arranged at the bottom of the lower chamber of the fermentation tank 101, and the fan 110 is communicated with the partition plate 102 and is located below the partition plate 102. The mixing mechanism is used for uniformly mixing the inert gas and the mist. The jet nozzle 111 is communicated with the partition plate 102 and is located in the upper chamber above the partition plate 102. Since both the intake pipe 107 and the water inlet pipe 108 are communicated with the lower chamber of the fermentation tank 101, inert gas and water mist can be introduced into the lower chamber of the fermentation tank 101 through the intake pipe 107 and the water inlet pipe 108 respectively. The heating plate 109 can heat the introduced inert gas and water mist. The suction force generated when the fan 110 operates can transfer the inert gas and water mist in the lower chamber of the fermentation tank 101 into the jet nozzle 111 in the upper chamber of the fermentation tank 101 and finally spray out from the jet nozzle 111 to provide an anaerobic fermentation environment for the fish bait in the upper chamber of the fermentation tank 101.

[0024] In this embodiment, the internal space of the fermentation tank 101 is divided into upper and lower chambers by the partition plate 102. Then, inert gas and water mist are introduced into the lower chamber of the fermentation tank 101 through the intake pipe 107 and the water inlet pipe 108 respectively. The heating plate 109 heats the inert gas and water mist. After heating, the fan 110 transfers the inert gas and water mist into the upper chamber of the fermentation tank 101 to provide an anaerobic fermentation environment for the fish bait spread on the fermentation plate 105 in the upper chamber of the fermentation tank 101.

[0025] After the fish bait ferments for a period of time, all the fermentation plates 105 are rotated in sequence within the two fixing plates 104, so that the fish bait on the fermentation plates 105 falls onto the support plate 103 and the fermentation plates 105 in sequence, realizing the flipping of the fish bait, so that the part of the fish bait in contact with the fermentation plate 105 at the bottom can also be fully fermented, thereby improving the fermentation effect of the fish bait and solving the technical problem that in the existing anaerobic fermentation device, the fish bait is spread on the fermentation plate 105, resulting in that when the fish bait on the fermentation plate 105 is anaerobically fermented, the part of the fish bait in contact with the fermentation plate 105 at the bottom will not be fully fermented, thus reducing the fermentation effect of the fish bait.

[0026] Secondly, the driving mechanism includes a driving part 112 and a buffer spring 113. The output end of the driving part 112 is connected to the support plate 103. The driving part 112 is arranged on the partition plate 102. The buffer spring 113 is arranged between the partition plate 102 and the support plate 103. The driving part 112 is a hydraulic telescopic rod. Since the output end of the driving part 112 is connected to the support plate 103 and drives the support plate 103 to move up and down in the upper cavity of the fermentation box 101, driving the buffer spring 113 to expand and contract in the upper cavity of the fermentation box 101. Since the buffer spring 113 has a self-restoring effect, the buffer spring 113 buffers the up and down movement of the support plate 103 to prevent the bait spread on the fermentation plate 105 from falling off the fermentation plate 105 due to the too-fast movement of the support plate 103.

[0027] Meanwhile, the mixing mechanism includes a transmission member, a rotating column 114 and stirring blades 115. The transmission member includes a transmission motor 116, a first gear 117, a second gear 118, a support seat 119, a stirring motor 120 and a screw 121. The transmission motor 116 is arranged outside the fermentation box 101. The first gear 117 is connected to the output shaft of the transmission motor 116 and is located on the side of the transmission motor 116 away from the fermentation box 101. The rotating column 114 penetrates through the fermentation box 101. The second gear 118 meshes with the first gear 117 and is arranged outside the rotating column 114, driving the first gear 117 to rotate along its own axis, thereby driving the second gear 118 to rotate along its own axis, and further driving the rotating column 114 to rotate along its own axis in the lower cavity of the fermentation box 101. Finally, the transmission member is used to drive the stirring blades 115 to move horizontally in the rotating column 114 and rotate in the lower cavity of the fermentation box 101, including: the support seat 119 is arranged on the side of the fermentation box 101 outside and close to the second gear 118. The stirring motor 120 is arranged on the support seat 119. The screw 121 is connected to the output end of the stirring motor 120 and drives the screw 121 to rotate along its own axis in the rotating column 114 and is located inside the rotating column 114.

[0028] The stirring blade 115 has threaded holes, the screw rod 121 has external threads, and the threaded holes of the stirring blade 115 are engaged with the external threads of the screw rod 121; the stirring blade 115 is slidably arranged in the rotating column 114; the rotating column 114 has a chute 123, and sliding plates 124 are arranged on both the left and right sides outside the stirring blade 115. The sliding plates 124 are located in the chute 123 and slide left and right in the chute 123. The rotating column 114 has a convex ring, the fermentation tank 101 has a rotating groove, and the convex ring of the rotating column 114 is located in the rotating groove of the fermentation tank 101 and rotates along its own axis in the rotating groove of the fermentation tank 101, so that the stirring blade 115 can move along the trajectory of the thread outside the screw rod 121, thereby enabling the stirring blade 115 to move horizontally in the lower chamber of the fermentation tank 101.

[0029] When using the anaerobic fermentation device for processing fish bait in this embodiment, start the driving part 112, so that the power output by the output end of the driving part 112 drives the support plate 103 to move up and down in the upper chamber of the fermentation tank 101, driving the fixing plate 104 to move up and down in the upper chamber of the fermentation tank 101, thereby driving the fermentation plate 105 and the cover plate 106 to move up and down in the upper chamber of the fermentation tank 101.

[0030] When both the fermentation plate 105 and the cover plate 106 are removed from the upper chamber of the fermentation tank 101, evenly spread the fish bait on the fermentation plate 105, and then drive the support plate 103 to move down, driving the fixing plate 104 to move down, thereby driving the fermentation plate 105 and the cover plate 106 to move down until the cover plate 106 completely closes the internal space of the upper chamber of the fermentation tank 101.

[0031] After that, connect the air inlet pipe 107 and the water inlet pipe 108 to the storage devices storing inert gas and water mist respectively, introduce inert gas into the air inlet pipe 107, then introduce water mist into the water inlet pipe 108, and start the heating plate 109 to let the heating plate 109 heat the inert gas and water mist.

[0032] While heating the inert gas and the water mist, start the drive motor 116 so that the power output from the output shaft of the drive motor 116 drives the first gear 117 to rotate along its own axis, thereby driving the second gear 118 to rotate along its own axis, and further driving the rotating column 114 to rotate along its own axis in the lower chamber of the fermentation tank 101. Through the rotation of the rotating column 114 along its own axis in the lower chamber of the fermentation tank 101, drive the stirring blade 115 to rotate along the axis of the rotating column 114 in the lower chamber of the fermentation tank 101. Start the stirring motor 120 so that the power output from the output end of the stirring motor 120 drives the screw 121 to rotate along its own axis in the rotating column 114, so that the stirring blade 115 can move along the trajectory of the thread outside the screw 121, and further make the stirring blade 115 can move laterally in the lower chamber of the fermentation tank 101. Combining the rotation of the stirring blade 115 along the axis of the rotating column 114 in the lower chamber of the fermentation tank 101, the inert gas and the water mist in the lower chamber of the fermentation tank 101 are evenly mixed.

[0033] After heating, start the fan 110 so that the suction force generated when the fan 110 operates can suck the inert gas and the water mist in the lower chamber of the fermentation tank 101 into the jet nozzle 111 and then spray out from the jet nozzle 111 to provide an anaerobic fermentation environment for the bait on the fermentation plate 105.

[0034] After fermenting the bait for a period of time, first start the rotating motor 122 at the bottom layer so that the rotation of the output shaft of the rotating motor 122 drives the fermentation plate 105 at the bottom layer to rotate along the axis of the output shaft of the rotating motor 122, thereby driving the bait on the fermentation plate 105 to rotate along the axis of the output shaft of the rotating motor 122, so that the bait on the fermentation plate 105 is flipped 180 degrees, and the bait will fall onto the support plate 103.

[0035] Then start the rotating motor 122 on the adjacent upper layer, so as to drive the fermentation plate 105 on the adjacent upper layer to rotate along the axis of the output shaft of the rotating motor 122 at the corresponding position, and further drive the bait on the fermentation plate 105 to rotate along the axis of the output shaft of the rotating motor 122, so that the bait on the fermentation plate 105 on the adjacent upper layer is flipped 180 degrees, and the bait will fall onto the fermentation plate 105 on the adjacent lower side.

[0036] Repeat the operation of the previous step to let the bait on the upper layer all fall onto the fermentation plate 105 on the adjacent lower layer, so that the part of the bait bottom in contact with the fermentation plate 105 can also be fully fermented, thereby improving the fermentation effect of the bait and solving the technical problem that in the existing anaerobic fermentation device, the bait is spread on the fermentation plate 105, resulting in insufficient fermentation of the part of the bait bottom in contact with the fermentation plate 105 during anaerobic fermentation of the bait on the fermentation plate 105, thus reducing the fermentation effect of the bait.

[0037] Second Embodiment: Based on the first embodiment, please refer to Figure 4 , the present invention also provides an anaerobic fermentation method for bait processing, including the following steps: S101. Start the driving part 112, drive the support plate 103 to move up and down in the upper cavity of the fermentation tank 101 through the driving part 112, drive the fixing plate 104 to move up and down in the upper cavity, so as to drive the fermentation plate 105 and the cover plate 106 to move up and down in the upper cavity.

[0039] S102. When both the fermentation plate 105 and the cover plate 106 are moved out of the upper cavity, evenly spread the bait on the fermentation plate 105, and then move the fermentation plate 105 and the cover plate 106 downward until the cover plate 106 completely closes the upper cavity.

[0040] Specifically, when both the fermentation plate 105 and the cover plate 106 are moved out of the upper cavity of the fermentation tank 101, evenly spread the bait on the fermentation plate 105, and then drive the support plate 103 to move downward, drive the fixing plate 104 to move downward, so as to drive the fermentation plate 105 and the cover plate 106 to move downward until the cover plate 106 completely closes the internal space of the upper cavity of the fermentation tank 101.

The heating plate 109 is started to heat the inert gas and the water mist by the heating plate 109.

[0043] S104. While heating the inert gas and the water mist, the stirring blades 115 are made to move horizontally and rotate in the lower chamber of the fermentation tank 101 to achieve uniform mixing of the inert gas and the water mist.

Through the rotation of the rotating column 114 along its own axis in the lower chamber of the fermentation tank 101, the stirring blades 115 are driven to rotate along the axis of the rotating column 114 in the lower chamber of the fermentation tank 101. The stirring motor 120 is started, so that the power output by the output end of the stirring motor 120 drives the screw 121 to rotate along its own axis in the rotating column 114, so that the stirring blades 115 can move along the thread track outside the screw 121, and further the stirring blades 115 can move horizontally in the lower chamber of the fermentation tank 101. Combining the rotation of the stirring blades 115 along the axis of the rotating column 114 in the lower chamber of the fermentation tank 101, uniform mixing of the inert gas and the water mist in the lower chamber of the fermentation tank 101 is achieved.

[0045] S105. After heating, the fan 110 is started. Under the suction of the fan 110, it is sucked into the jet nozzle 111 and then ejected from the jet nozzle 111 to provide an anaerobic fermentation environment for the bait on the fermentation plate 105.

[0046] Specifically, after heating, the fan 110 is started, so that the suction generated when the fan 110 operates can suck the inert gas and the water mist in the lower chamber of the fermentation tank 101 into the jet nozzle 111 and then eject them from the jet nozzle 111 to provide an anaerobic fermentation environment for the bait on the fermentation plate 105.
