Description

TECHNICAL FIELD

[0002] In the processing and production process of Dendrobium candidum, skin removal is a key process for improving product quality and subsequent processing efficiency. Currently, the industry mainly uses manual rubbing and peeling and mechanical grinding to remove the skin of Dendrobium candidum. Manual processing relies on manual rubbing of Dendrobium stem by operators, and the skin and flesh are separated by external force. The mechanical grinding method uses a roller or grinding cavity with grinding protrusions to achieve skin peeling by friction generated by the rotation of the parts. Some devices also use water flow to assist in separating the skin and raw materials. These existing technologies have been applied to a certain extent in small-scale production or simple processing scenarios.

[0003] However, the existing Dendrobium candidum skin removal technology has the following problems. The manual processing method is limited by the operator's proficiency and physical strength, and the processing capacity per unit time is small, which cannot meet the needs of large-scale production. The labor intensity is high, and the labor cost is high. Although the mechanical grinding method has improved the efficiency compared to manual processing, the existing equipment cannot achieve uniform stress and continuous conveying of the raw materials due to the slender and fragile shape of the Dendrobium stem. This can cause damage to the raw materials or incomplete peeling of the skin in some areas.

[0039] Drive motor 25 is fixedly connected on the lateral wall of base 1, and the output end of drive motor 25 is fixedly connected with motor gear 26, and motor gear 26 is engagedly connected with rotating gear 27, and rotating gear 27 is fixedly connected on the lateral wall of peeling shell 21, and rotating gear 27 is penetrated with heating pipe 28 on one side, and heating pipe 28 is fixedly connected on the lateral wall of base 1.

[0040] Specifically, external heating gas pump inputs heating gas to heating pipe 28 through connecting port 29, drive motor 25 drives motor gear 26 to rotate, and meshing rotating gear 27 makes peeling shell 21 and internal sieve skin barrel 22 rotate.Heating gas is evenly blown to dendrobium officinale through the gas outlet 34 of the swing assembly 3, and at the same time, the gas pressure assembly 5 pushes the piston plate 56 by the gas pressure, so that the piston rod 58 slides in the second track groove 59, and the auxiliary raw material is turned over.The rotating sieve skin barrel 22 cooperates with the hot gas flow to separate the epidermis of dendrobium officinale from the flesh, and the exfoliated epidermis is discharged through the slag discharge assembly 6, and the peeling operation is completed.

[0041] Through the combination of hot gas flow and mechanical rotation, the traditional mechanical grinding is avoided to avoid excessive extrusion, reduce the damage of dendrobium officinale and protect the integrity of raw materials.The swing assembly 3 realizes uniform coverage of heating gas, the gas pressure assembly 5 assists the raw material to turn over, and the skin peeling is more thorough without additional sorting process.The slag discharge assembly 6 automatically discharges the skin residue, cooperates with the design of feed pipe 23 and material taking opening 24, realizes continuous production, greatly improves processing efficiency and reduces labor cost.

[0042] One side of heating pipe 28 is provided with swing assembly 3, and swing assembly 3 is used to improve the heating effect of heating gas on dendrobium officinale, and swing assembly 3 includes rectangular cylinder 31 fixedly connected on one side of heating pipe 28, swing block 33 is arranged on the lateral wall of rectangular cylinder 31, swing block 33 is provided with gas outlet 34, and gas outlet 34 is communicated with connecting port 29.

[0043] The side wall of the rectangular cylinder 31 is provided with an oscillation groove 32, and the oscillation groove 32 is rotationally connected with an oscillation block 33. The oscillation block 33 is formed by the intersection of two cylinders, and the side wall of the oscillation block 33 is fixedly connected with an oscillation gear ring 35. The oscillation gear ring 35 is meshingly connected with an oscillation rack 36. The oscillation block 33 and the oscillation rack 36 are provided with multiple groups, and the adjacent two groups of oscillation racks 36 are connected through connecting rods 37.

[0044] Specifically, compared with the fixed heating mode and the uneven heating of raw materials in the prior art, the oscillation assembly 3 is self-driven to oscillate by gas flow, without the need for an additional power source, thereby reducing energy consumption and simplifying the structure. The reciprocating oscillation of the oscillation block 33 allows the heating gas to cover a wider range, avoids local overheating that causes damage to the raw materials, and prevents the skin in some areas from being difficult to peel due to insufficient heating. The design of multiple groups of oscillation blocks 33 and racks improves the heating uniformity, forms gaps between the skin and the flesh of the Dendrobium candidum due to the difference in thermal expansion and cold contraction, and lays a foundation for subsequent peeling.

[0045] The oscillation assembly 3 is self-driven to oscillate by gas flow, thereby reducing energy consumption and simplifying the structure.

[0046] The driving of the oscillation block 33 by the oscillation rack 36 is realized through a control assembly 4. The control assembly 4 includes a fixed shaft 41 fixedly connected to the inner wall of the heating pipe 28. The other end of the fixed shaft 41 is rotationally connected with an inner shaft 42. The other end of the inner shaft 42 is inserted into an outer cylinder 43. The outer cylinder 43 is provided with a first track groove 44. A track sliding block 45 is slidably connected in the first track groove 44. The track sliding block 45 is fixedly connected to the inner wall of the inner shaft 42.

[0047] One side of the outer cylinder 43 is fixedly connected with the swing rack 36 through the connecting rod 37, and the side wall of the inner shaft 42 is fixedly connected with the turbine blade 46, and the rotation of the turbine blade 46 is driven by the gas flow in the heating pipe 28.

[0048] Specifically, the operation of the control assembly 4 relies on the gas flow in the heating pipe 28 as a power source, which matches the physical environment of food processing for removing the Dendrobium candidum skin. When the heated gas input by the heating gas pump flows through the heating pipe 28, it pushes the turbine blade 46 on the side wall of the inner shaft 42 to rotate, and the inner shaft 42 is fixed to the inner wall of the heating pipe 28 through the fixed shaft 41, and can only rotate itself. The track slider 45 on the inner wall of the inner shaft 42 is embedded in the first track groove 44 of the outer cylinder 43, and when the turbine blade 46 drives the inner shaft 42 to rotate, the track slider 45 slides along the first track groove 44, converting the rotary motion into reciprocating linear motion of the outer cylinder 43. The outer cylinder 43 is fixed with the swing rack 36 through the connecting rod 37, and the reciprocating motion drives the swing rack 36 to move synchronously, and then engages the swing tooth ring 35 of the swing block 33, so that the swing block 33 reciprocates in the swing groove 32 of the rectangular cylinder 31, and finally realizes the dynamic injection of the heated gas.

[0049] The control assembly 4 is self-driven by the gas flow in the heating pipe 28, which simplifies the structure and reduces energy consumption, which meets the energy-saving needs of food processing. The design of converting gas flow into swing power realizes the integration of heating and swing driving, avoids the coordination error between power source and heating system in the prior art, accurately matches the swing frequency and gas flow, ensures that the heated gas uniformly covers the Dendrobium candidum, and prevents local overheating damage or insufficient heating from causing incomplete skin peeling. With the design of multiple swing blocks 33, the skin removal efficiency and raw material integrity are greatly improved, and the pain points of the prior art that are difficult to balance industrialized continuous production and product quality are solved.

[0050] The sieve skin barrel 22 is provided with a gas pressure assembly 5, which includes a fixed disc 51 fixedly connected to the side wall of the heating pipe 28, and the fixed disc 51 is fixedly connected with a gas pressure rod 52 on one side. The pressure groove 53 and the gas outlet groove 54 are communicated with each other, and the bottom of the gas pressure rod 52 is provided with a gas outlet hole 55 which is communicated with the gas outlet groove 54.

[0051] The piston plate 56 is slidably connected in the pressure groove 53, one side of the piston plate 56 is connected with the pressure groove 53 through the piston spring 57, the other side of the piston plate 56 is fixedly connected with the piston rod 58, and the other end of the piston rod 58 is slidably connected in the second track groove 59 which is opened in the sieve skin barrel 22.

[0052] Specifically, when the skin barrel 22 rotates synchronously with the peeling shell 21, the second track groove 59 opened in the inner wall of the skin barrel 22 rotates synchronously, driving the piston rod 58 slidingly connected in the groove to move synchronously. When the second track groove 59 rotates to the high position, the piston rod 58 pushes the piston plate 56 to move leftward in the pressure groove 53 of the air pressure rod 52 under the action of the track guide, at this time, the piston plate 56 compresses the piston spring 57 and reduces the internal space of the pressure groove 53; when the second track groove 59 rotates to the bottom, the pushing force of the track on the piston rod 58 disappears, the instant elastic force of the compressed piston spring 57 is released, quickly pushing the piston plate 56 to retreat rightward, so that the space in the pressure groove 53 is rapidly expanded to form a transient air pressure. The air pressure pushes the gas in the pressure groove 53 into the air outlet groove 54, and then the gas is delivered to the skin barrel 22 through the air outlet hole 55 at the bottom of the air pressure rod 52, so as to realize the impact on the surface of the dendrobium candidum and improve the cleaning effect on the surface of the dendrobium candidum.

[0053] The air pressure assembly 5 generates air pressure relying on the instant elastic force of the spring, and the flexible air flow impact replaces the rigid contact, which can minimize the damage to the raw materials, protect the integrity of the dendrobium candidum and the subsequent processing value, and solve the problem of traditional mechanical peeling. The air pressure assembly 5 is driven by the rotary motion of the skin barrel 22, which greatly reduces the energy consumption and structural complexity of the equipment. At the same time, the pulse air flow generated by the transient air pressure can quickly act on the gap between the surface and the flesh of the dried dendrobium candidum, and the peeling efficiency is much higher than that of the traditional continuous air flow or water flow washing, and no additional sorting process is needed, which can be seamlessly adapted to the continuous production process of the device, significantly improving the processing efficiency and reducing the labor cost.

[0054] The side wall of the peeling shell 21 is provided with a residue discharging assembly 6, which includes a residue discharging groove 61 and a rotating groove 63 opened in the side wall of the peeling shell 21. The residue discharging groove 61 is provided with two groups of symmetrical residue discharging plates 62, the two sides of the symmetrical residue discharging plates 62 are fixedly connected with rotating shafts 64, and the rotating shafts 64 are rotatably connected in the rotating groove 63. One of the rotating shafts 64 and the rotating groove 63 are connected by a torsion spring 65.

[0055] The other end of the rotating shaft 64 is fixedly connected with a counter gear set 66, one side of the counter gear set 66 is fixedly connected with a driving shaft 67, the other end of the driving shaft 67 is fixedly connected with a residue discharging gear 68, the residue discharging gear 68 is meshingly connected with a crescent tooth plate 69, and the crescent tooth plate 69 is fixedly connected to the side wall of the base 1.

[0056] Specifically, when the peeling shell 21 is driven to rotate by the driving motor 25, the side wall residue discharge gear 68 rotates synchronously with the shell and continuously engages with the crescent tooth plate 69 fixed on the base 1. The engagement drives the residue discharge gear 68 to drive the counter gear set 66 to rotate through the driving shaft 67, so that the rotating shafts 64 of the two sets of symmetrical residue discharge plates 62 rotate in opposite directions along the rotating grooves 63, the torsional springs 65 are compressed, and the residue discharge grooves 61 are opened. At this time, the epidermis and residue of Dendrobium candidum screened by the skin barrel 22 are discharged from the residue discharge grooves 61 under the action of the centrifugal force generated by the rotation of the shell. When the residue discharge gear 68 is out of the meshing area of the crescent tooth plate 69, the torsional spring 65 is reset to drive the rotating shaft 64 to rotate reversely, the symmetrical residue discharge plates 62 close the residue discharge grooves 61, and one residue discharge cycle is completed.

[0057] The residue discharge assembly 6 is designed through gear engagement and resetting of the torsional spring 65, realizes real-time automatic discharge of residue, does not need manual intervention, greatly improves production efficiency. The reverse opening and closing design of the symmetrical residue discharge plates 62, in combination with the physical action of the centrifugal force, ensures smooth discharge of residue and avoids blockage of the residue discharge channel, and meanwhile, the closing is good in sealing property, prevents leakage of heating gas and falling of raw materials. Compared with the static filtration of the prior art, the dynamic and cyclic residue discharge mode can continuously separate epidermis and raw materials, reduces subsequent sorting processes, and guarantees product purity.

[0058] The scheme also provides a use method of the epidermis removing device for Dendrobium candidum production, and the use method comprises the following steps:

[0059] S1: fix the base on a stable table top, connect an external heating gas pump through the connecting port, check the firmness of each component, and ensure that the material taking port and the residue discharge groove are well closed;

[0060] S2: start the device for preheating, after stable hot gas flow is output by the heating pipe, uniformly input Dendrobium candidum raw materials through the feeding pipe, and control the feeding amount to adapt to the processing capacity of the device;

[0061] S3: start the driving motor to drive the peeling shell and the skin barrel to rotate, the hot gas is uniformly sprayed through the swing assembly, and the pulse gas flow of the air pressure assembly is used to assist the epidermis peeling;

[0062] S4: the residue discharge assembly is automatically opened and closed along with the rotation of the shell, the epidermis residue is discharged through the residue discharge groove, and the state of the raw materials is observed in the process to ensure that there is no excessive accumulation or damage;

[0063] S5: after the peeling is completed, the device is turned off, the processed Dendrobium candidum is taken out from the material taking port, the skin barrel and the residue discharge channel are cleaned, and the device is kept clean for next use.

[0064] The working principle of the present application is as follows:

[0065] The external heating air pump inputs heating gas to the heating pipe 28 through the connecting port 29, the driving motor 25 drives the motor gear 26 to rotate, the meshed rotating gear 27 rotates the peeling shell 21 and the internal screen shell 22. When the heating gas flows through the heating pipe 28, the turbine blade 46 is pushed to rotate, the inner shaft 42 rotates, the track sliding block 45 slides along the No. 1 track groove 44 of the outer cylinder 43, the rotating motion is converted into the reciprocating linear motion of the outer cylinder 43, the connecting rod 37 drives the swing rack 36 to move, the meshed driving swing gear ring 35 drives the swing block 33 to reciprocate. The heating gas uniformly blows to the Dendrobium candidum sent by the feeding pipe 23 through the gas outlet 34 of the swing block 33, the rotating screen shell 22 cooperates with the hot gas flow to form a gap between the epidermis and the flesh due to thermal expansion and cold contraction, and gradually separates, so that the raw materials are uniformly stressed.

[0066] When the screen shell 22 rotates with the peeling shell 21, the No. 2 track groove 59 of the inner wall drives the piston rod 58 to move. When the track groove turns to the high position, the piston rod 58 pushes the piston plate 56 to compress the piston spring 57, so that the space of the pressure groove 53 is reduced; when the track groove turns to the bottom, the piston spring 57 resets the piston plate 56 to retreat, so that the space of the pressure groove 53 is sharply expanded to form a transient gas pressure. The gas pressure pressurizes the gas into the gas outlet groove 54, and then the gas is sprayed out through the gas outlet hole 55 at the bottom of the gas pressure rod 52. The pulsed airflow impacts the epidermis of the Dendrobium candidum, assists in peeling the loosened epidermis, pushes the raw materials to turn over, ensures that the epidermis is peeled more completely, avoids local residues, and does not damage the raw material body.

[0067] When the peeling shell 21 rotates, the side wall of the shell is continuously engaged with the crescent tooth plate 69 on the base 1, the driving residue gear 68 drives the counter rotating gear set 66 to rotate through the driving shaft 67, the rotating shaft 64 of the two symmetrical residue discharge plates 62 rotates in opposite directions and compresses the torsional spring 65, and the residue discharge groove 61 is opened. The epidermis residue screened by the screen shell 22 is discharged from the residue discharge groove 61 under the action of the centrifugal force generated by the rotation of the shell. When the residue discharge gear 68 is disengaged from the meshing area of the crescent tooth plate 69, the torsional spring 65 resets the rotating shaft 64 to reverse, the symmetrical residue discharge plates 62 close the residue discharge groove 61, and a cycle of automatic residue discharge is completed, so that the residue is separated in real time without manual intervention.
