Abstract
Description
Technical Field
[0001] This invention relates to the field of fresh air purification equipment technology, specifically a fresh air purification temperature and humidity integrated air conditioning unit for sea cucumber processing workshops. Background Technology
[0002] Air drying to lock in freshness is one of the core processes in sea cucumber processing. The cleanliness, temperature, and humidity of the drying environment directly determine the finished product quality, nutrient retention rate, and storage period of the dried sea cucumber. Currently, most sea cucumber processing workshops use ordinary ventilation equipment or simple air conditioning units for the air drying process, which generally suffer from insufficient dehumidification capacity and poor control precision. Sea cucumbers require a continuously stable low-humidity environment during air drying. Existing equipment is unable to quickly remove the large amount of moisture carried by fresh air and workshop return air, which can easily lead to a prolonged air drying period and mold growth on the surface of the sea cucumbers, seriously affecting product quality and food safety. On the other hand, some strong dehumidification equipment can easily cause the environmental humidity to be too low, causing the sea cucumbers to crack and lose nutrients, thus failing to achieve the desired freshness-locking effect.
[0003] The air purification level of existing equipment is also insufficient to meet the requirements of food processing. During the drying process of dried sea cucumbers, the air is directly exposed to the workshop air. Ordinary filter equipment can only intercept large particles of dust and cannot effectively remove pollutants such as PM2.5, microorganisms, and floating dust, easily causing secondary contamination of the dried sea cucumbers, which does not comply with food production hygiene standards. At the same time, the drying workshop has high cleanliness requirements. When replacing filter elements and cleaning dust removal components, accumulated dust and pollutants in the existing equipment can easily spread into the air supply duct and enter the drying area with the airflow, further increasing the risk of contamination of the dried sea cucumbers.
[0004] In addition, existing equipment suffers from drawbacks such as high operating noise and low functional integration. Prolonged continuous operation of the unit generates significant noise, and the temperature and humidity control functions are fragmented, failing to achieve integrated and precise control of fresh air, purification, dehumidification, temperature regulation, and humidification, making it difficult to maintain the stable process environment required for drying and preserving the freshness of dried sea cucumbers. Summary of the Invention
[0005] To address the shortcomings of existing technologies, this invention provides an integrated air conditioning unit for fresh air purification and temperature and humidity control in sea cucumber processing workshops. This unit solves the problems of insufficient dehumidification accuracy, substandard purification levels, easy maintenance leading to secondary pollution, and difficulty in meeting the requirements of the dried sea cucumber drying and preservation process in existing air handling equipment for sea cucumber processing and drying workshops.
[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: a fresh air purification and temperature and humidity integrated air conditioning unit for sea cucumber processing workshop, comprising a shell, wherein a fresh air inlet, an air outlet and a return air outlet are respectively provided at both ends and the top of the shell, and a primary filter, a dehumidifier, an electronic dust removal purifier, a secondary filter, a noise reduction and silencing device and a temperature and humidity control device are sequentially arranged inside the shell along the direction from the fresh air inlet to the air outlet; The dehumidifier includes a first frame, and a plurality of inclined wall plates are arranged from top to bottom on the inner side of the first frame. The inclined wall plates are inclined along the air inlet to air outlet direction, and an air guide cavity is formed between two adjacent inclined wall plates. In a side view projection, the bottom end of the upper inclined wall plate and the top end of the lower inclined wall plate are on the same horizontal plane. The noise reduction and silencing device includes a frame and several noise reduction units disposed on the frame; The temperature and humidity control device includes a third frame, and a heating unit and a humidification unit are arranged sequentially along the air inlet to air outlet direction inside the third frame.
[0007] Preferably, each of the inclined wall panels has a plurality of fins at its bottom, the length of the plurality of fins decreasing sequentially along the air inlet to air outlet direction, each of the fins being vertically arranged, and the bottom of each fin facing the top surface of the fin located below.
[0008] Preferably, a liquid guide pipe is vertically arranged on one side of the bottom end of the inclined wall plate, and a liquid outlet is opened at the connection between the liquid guide pipe and each inclined wall plate. The bottom of the liquid guide pipe is connected to a liquid collection tank.
[0009] Preferably, the noise reduction unit includes a hollow fourth frame, the inner wall of which is provided with an aluminum silicate layer, a non-woven fabric layer and a perforated metal mesh from the outside to the inside; an air guide plate is inclinedly arranged in the hollow cavity of the fourth frame, and the air guide plate divides the hollow cavity into an upper cavity and a lower cavity.
[0010] Preferably, the humidification unit includes a first metal mesh and a second metal mesh vertically arranged within a third frame, with a humidification cavity formed between the first metal mesh and the second metal mesh. The humidification cavity has an array of atomizing nozzles arranged on a support, and the atomizing nozzles are connected to a water source through pipes.
[0011] Preferably, the heating unit includes a stand disposed within the third frame, and the stand is provided with a plurality of heating resistance wires.
[0012] Preferably, an air distribution plate is provided between the dehumidifier and the electronic dust removal purifier, and the air distribution plate is a perforated mesh plate.
[0013] Preferably, the front side of the noise reduction and silencing device is provided with a barrier seal, the barrier seal includes a second frame, and the interior of the second frame is provided with a plurality of gates rotatably connected by a shaft from top to bottom, wherein when the gates are flipped to an upright state, two adjacent gates abut against each other; when the gates are flipped to a horizontal state, an air passage is formed between two adjacent gates. One end of the shaft of each gate extends out of the second frame and is fixed with one end of the swing arm. The other end of the swing arm is rotatably connected to a drive rod. Two adjacent drive rods are connected by a swivel joint. An electric cylinder is provided at the top of the second frame. The output end of the electric cylinder passes through the second frame and is connected to the uppermost drive rod. The second frame has a side latch shell that can accommodate the drive rod and the swing arm.
[0014] Preferably, both the fresh air inlet and the air outlet are equipped with protective nets.
[0015] Preferably, the connection between the return air vent and the housing is located between the primary filter and the dehumidifier.
[0016] The beneficial effects of this invention are: 1. The dehumidifier increases the air contact area through the inclined wall panels, promoting rapid condensation of water vapor. Combined with the gradually changing length of the fins at the bottom, it further enhances heat exchange and significantly improves dehumidification efficiency. It can quickly reduce the humidity of fresh air and return air in the workshop, shorten the drying cycle of dried sea cucumbers, and prevent the sea cucumbers from becoming moldy due to high humidity. The condensate is collected along the inclined wall panels and then discharged into the collection tank through the liquid guide pipe, avoiding the accumulation of liquid and the growth of bacteria, which meets the hygiene requirements of food processing.
[0017] 2. The first-stage filter intercepts large particles of dust, hair, and other debris. The electronic dust purifier uses high-voltage electrostatic adsorption to efficiently adsorb fine particulate matter such as PM2.5 and pollen. The second-stage filter further removes ultrafine particles such as bacteria and microorganisms. The three-stage purification process ensures that the air sent into the drying workshop meets the cleanliness standards, preventing the dried ginseng from being contaminated by dust and microorganisms during the drying process and ensuring the safety of the product.
[0018] 3. The heating resistance wire can stably control the air supply temperature within the suitable range for low-temperature air drying of dried sea cucumbers, ensuring drying efficiency while avoiding high temperature damage to the active nutrients of sea cucumbers; the humidification unit can perform fine humidity compensation for the air supply, preventing the sea cucumbers from cracking and losing nutrients due to excessively low ambient humidity, so that the air drying environment is always maintained within the optimal temperature and humidity range for locking in the freshness of dried sea cucumbers, thereby improving the quality and storage period of the finished dried sea cucumbers.
[0019] 4. The barrier is installed between the purification module and the clean air supply module. When the filter element is replaced or the dust removal components are cleaned, the gate can automatically close to isolate the inside of the housing into two independent cavities, effectively preventing dust and pollutants generated during maintenance from entering the subsequent clean air duct, avoiding contamination of the dry air drying operation environment, and reducing product safety risks.
[0020] 5. The noise reduction unit diverts airflow through the air guide plate and absorbs noise step by step through multiple layers of sound-absorbing materials, which greatly reduces the aerodynamic noise of airflow and the vibration noise of equipment. The unit will not cause noise interference to the workshop environment even after long-term continuous operation, and is suitable for the continuous operation of the dry ginseng drying process around the clock.
[0021] 6. The return air inlet is connected between the primary filter and the dehumidifier. The return air and fresh air in the workshop are mixed and treated in a unified manner, which not only reduces the energy consumption of temperature and humidity control, but also maintains the continuous stability of environmental parameters in the drying workshop, ensuring that the drying process of dried products is uniform and consistent.

[0024] To better explain and facilitate understanding of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Various changes can be made to the implementation schemes as long as the effects of the present invention can be achieved.
[0026] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.
[0027] like Figures 1-10 As shown in the illustration, this embodiment discloses an integrated air conditioning unit for fresh air purification, temperature and humidity control in a sea cucumber processing workshop. It includes a housing 1, with a fresh air inlet 3, an air outlet 5, and a return air inlet 2 respectively located at both ends and the top of the housing 1. Protective nets 4 are installed at both the fresh air inlet 3 and the air outlet 5. Specifically, a fan is installed at the fresh air inlet 3 to introduce outside natural air into the housing 1. The air outlet 5 is used to deliver purified, temperature- and humidity-controlled air into the sea cucumber drying workshop to maintain the clean and stable temperature and humidity environment required for the drying process. The return air inlet 2 is responsible for drawing in air from the drying workshop for circulation and purification, improving energy efficiency and ensuring stable environmental parameters in the workshop.
[0028] like Figure 2As shown in this embodiment, the housing 1 is equipped with a primary filter 6, a dehumidifier 7, an electronic dust collector 9, a secondary filter 10, a noise reduction and silencing device 12, and a temperature and humidity control device 13 arranged sequentially along the direction from the fresh air inlet 3 to the air outlet 5 inside the housing 1. In addition, the connection between the aforementioned return air outlet 2 and the housing 1 is located between the primary filter 6 and the dehumidifier 7. It should be noted in detail that the primary filter 6 is a coarse filter that filters larger particles in the air, such as dust, hair, and insects. It mainly intercepts large particles with a diameter of 5 micrometers or more, preventing them from entering subsequent components, and is suitable for the outdoor fresh air environment of the sea cucumber processing workshop. The dehumidifier 7 is used to significantly reduce the humidity of the incoming air, meet the requirements of the dried sea cucumber drying process for a low humidity environment, accelerate the evaporation of moisture from the sea cucumber, and at the same time avoid mold growth caused by high humidity. The electronic dust collector 9 uses electrostatic adsorption to further remove fine particulate matter (such as PM2.5, bacteria, pollen, etc.) from the air, improving air cleanliness. The secondary filter 10 is a fine filter that removes fine particulate matter (such as bacteria, viruses, smoke, etc.) with a diameter of 0.3 micrometers or larger, meeting the air cleanliness standards of food processing workshops and preventing contamination of dried sea cucumbers. The noise reduction and silencing device 12 reduces the noise generated during continuous operation of the equipment, minimizing the impact of the unit on the workshop environment when the dried sea cucumbers are dried all day long. The temperature and humidity control device 13 precisely regulates the temperature and humidity of the air supplied to the drying workshop, stabilizing the environmental parameters within the optimal range for drying and preserving the freshness of dried sea cucumbers, avoiding excessively high temperatures that damage nutrients, excessively low humidity that causes the sea cucumbers to crack, or excessively high humidity that prolongs the drying cycle.
[0029] like Figures 3-5 As shown, the dehumidifier 7 includes a first frame 71, and a plurality of inclined wall plates 72 are arranged from top to bottom on the inner side of the first frame 71. The inclined wall plates 72 are inclined along the air inlet to air outlet direction, and an air guide cavity 73 is formed between two adjacent inclined wall plates 72. When the gas passes through the dehumidifier 7, the gas passes through the air guide cavity 73. In the side view projection, the bottom end of the upper inclined wall plate 72 and the top end of the lower inclined wall plate 72 are on the same horizontal plane, so that the gas can fully contact the upper and lower surfaces of the inclined wall plate 72. During the contact process, water vapor is retained on the inclined wall plate 72, so that condensation is generated on the surface of the inclined wall plate 72, thereby achieving the purpose of efficiently removing moisture from the air. Furthermore, due to the inclined arrangement, the condensation can flow towards the bottom, realizing the guiding and collection of condensed water, and avoiding the accumulation of liquid and the growth of microorganisms.
[0030] Furthermore, specifically as follows Figure 5As shown, multiple fins 76 are provided at the bottom of each inclined wall plate 72. The length of the multiple fins 76 decreases sequentially along the air inlet to air outlet direction. Each fin 76 is vertically arranged, and its bottom faces the top surface of the fin 76 located below. Multiple obstruction parts are formed in the air guide cavity 73. When the gas flows in the air guide cavity 73, it will fully contact the fins 76, which greatly increases the passive contact area when the gas flows, enhances the condensation effect, and further improves the dehumidification efficiency, which is suitable for the high humidity fresh air and return air treatment needs of the sea cucumber processing workshop.
[0031] Furthermore, a liquid guide pipe 74 is vertically installed on one side of the bottom of the inclined wall plate 72. Each connection point between the liquid guide pipe 74 and each inclined wall plate 72 has a liquid outlet 77. The bottom of the liquid guide pipe 74 is connected to a liquid collection tank 75. As the condensed water gathers on the inclined wall plate 72 and flows downward, it flows into the liquid guide pipe 74 through the liquid outlet 77 and then flows downward through the liquid guide pipe 74 to gather in the liquid collection tank 75. A drain pipe is installed on one side of the liquid collection tank 75 to discharge the water in the liquid collection tank 75, realizing centralized and closed discharge of condensate, avoiding the accumulation of water inside the shell and the growth of bacteria, which meets the hygiene requirements of food processing.
[0032] In this embodiment, as Figure 6 As shown, the noise reduction and silencing device 12 includes a frame and several noise reduction units 14 disposed on the frame, which are used to reduce noise when the filtered gas flows towards the air outlet 5, and are suitable for the long-term continuous operation of the dry ginseng drying workshop unit.
[0033] Specifically, the noise reduction unit 14 in this embodiment, such as Figure 7 As shown, the fourth frame 141 is hollow. The inner wall of the fourth frame 141 is provided with an aluminum silicate layer 142, a non-woven fabric layer 143, and a perforated metal mesh 144 from the outside to the inside. An air guide plate 145 is inclinedly arranged in the hollow cavity of the fourth frame 141, which divides the hollow cavity into an upper cavity 146 and a lower cavity 147. When the filtered gas flows into the hollow cavity, it first contacts the air guide plate 145 and is diverted to the upper cavity 146 and the lower cavity 147. At this time, the airflow is guided and refracted onto the perforated mesh 144. The noise is absorbed by the aluminum silicate layer 142 after passing through the non-woven fabric layer 143. Furthermore, the airflow is reflected multiple times by the air guide plate 145 and the perforated mesh 144 during the airflow process, which slows down the airflow speed and increases the noise reduction effect. This prevents the airflow from directly passing through the hollow cavity and reducing the noise reduction effect, thus ensuring a quiet working environment in the workshop.
[0034] In this embodiment, the temperature and humidity control device 13, such as Figure 8 As shown, it includes a third frame 131, with a heating unit and a humidifying unit arranged sequentially along the air inlet to air outlet direction on the inner side of the third frame, which are used to precisely control the air supply parameters to the appropriate range for drying and preserving the freshness of dried ginseng.
[0035] The heating unit includes a stand 132 set within the third frame 131, on which multiple heating resistance wires 133 are installed. When it is necessary to control the temperature of the gas to ensure that the temperature of the gas flowing into the drying workshop meets the process requirements for low-temperature drying and freshness preservation of dried sea cucumbers, the heating resistance wires 133 are turned on to raise the ambient temperature. When the filtered clean gas passes through, the gas is heated by the heating resistance wires 133, and the air supply temperature is stably controlled within the appropriate low-temperature range for drying, avoiding the destruction of the active nutrients of sea cucumbers by high temperatures, and achieving freshness preservation and drying.
[0036] For example, such as Figure 8 As shown, the humidification unit includes a first metal mesh 134 and a second metal mesh 135 vertically arranged within the third frame 131. A humidification cavity 136 is formed between the first metal mesh 134 and the second metal mesh 135. An array of atomizing nozzles 137, mounted on a support, is distributed within the humidification cavity 136. The atomizing nozzles 137 are connected to a water source via pipes. When excessive dehumidification leads to low supply air humidity, the humidification unit can controllably compensate for the air humidity, preventing surface cracking and nutrient loss in the dried ginseng due to low ambient humidity. During operation, selective control is possible. The number of times the atomizing nozzle 137 is opened determines the amount of water sprayed out through the atomizing nozzle 137 and its effect on the inner cavity of the humidifying jacket 136. At this time, the gas passing through is in full contact with the water mist, and the gas carries the water mist to the air outlet 5. In addition, during actual operation, the water mist will splash onto the first metal mesh 134 and the second metal mesh 135, forming droplets on the first metal mesh 134 and the second metal mesh 135. These droplets flow downward along the walls of the first metal mesh 134 and the second metal mesh 135 and collect in a water receiving tank to prevent the water from overflowing and breeding bacteria inside the housing 1.
[0037] For example, such as Figure 8 As shown, an air distribution plate 8 is provided between the dehumidifier 7 and the electronic dust removal purifier 9. The air distribution plate 8 is a perforated mesh plate. The function of the air distribution plate 8 is to distribute the dehumidified gas evenly so that the gas can flow evenly into the electronic dust removal purifier 9, ensuring that the purification components work evenly across the entire cross section, improving the overall purification efficiency, and ensuring that the cleanliness of the supplied air is stable and meets the standards.
[0038] Based on the above embodiments, such as Figure 2As shown, in this embodiment, a barrier closure 11 is provided on the front side of the noise reduction and silencing device 12. When cleaning or replacing the primary filter 6, electronic dust removal purifier 9, and secondary filter 10, the barrier closure 11 closes to divide the interior of the housing 1 into two cavities. At this time, the primary filter 6, electronic dust removal purifier 9, and secondary filter 10 are located in the air inlet cavity, while the noise reduction and silencing device 12 and temperature and humidity control device 13 are located in the clean air supply cavity. When cleaning or replacing the purification components, it can prevent untreated gas or dust generated during the replacement process from entering the clean air supply cavity, thus avoiding contaminants from entering the dry ginseng drying workshop with the air supply and causing product contamination, which complies with the hygiene and safety standards for food processing.
[0039] Specifically, the barrier closure 11 in this embodiment, such as Figure 9 and Figure 10 As shown, the device includes a second frame 111. Inside the second frame 111, multiple gates 113 are rotatably connected by a shaft from top to bottom. When the gate 113 is flipped to an upright position, two adjacent gates 113 abut against each other, and the barrier closure 11 is closed, blocking the airflow to the clean air supply side cavity. When the gate 113 is flipped to a horizontal position, an air passage opening is formed between two adjacent gates 113, and the two cavities are connected, which is the normal working state.
[0040] Furthermore, one end of the shaft of each gate 113 extends out of the second frame 111, and one end of the swing arm 116 is fixed to the extended end. The other end of the swing arm 116 is rotatably connected to the drive rod 115. An electric cylinder 112 is provided at the top of the second frame 111. The output end of the electric cylinder 112 passes through the second frame 111 and is connected to the uppermost drive rod 115. When working, when the electric cylinder 112 works to drive all the drive rods 115 to rise or fall, the drive rods 115 drive the swing arm 116 to swing. At this time, the shaft is rotated to make the gate 113 flip, so that the gate 113 is in the closed state and the open state respectively. Since the swing arm 116 is rotating, when it rotates to the horizontal state, it will drive the drive rod 115 to move to one side. Therefore, the drive rod 115 in this embodiment has a multi-section structure. Two adjacent drive rods 115 are connected by a hinge 117, so that two adjacent drive rods 115 can be folded freely to generate rotation to adapt to the swinging operation of the swing arm 116.
[0041] The second frame 111 has a side snap-fit shell 114 on its side that can accommodate the drive rod 115 and the swing arm 116; the side snap-fit shell 114 snaps and protects the drive rod 115 and the swing arm 116, preventing dust accumulation in the transmission structure and reducing the amount of cleaning and maintenance work.
[0042] The integrated air conditioning unit for fresh air purification and temperature and humidity control used in this sea cucumber processing workshop uses the casing 1 as the core carrier. Through the coordinated operation of internal components according to the logic of fresh air introduction, multi-stage treatment, and clean output, it achieves integrated functions of fresh air purification, efficient dehumidification, precise temperature and humidity control, quiet operation, and maintenance and pollution prevention. It is suitable for the process requirements of drying and preserving the freshness of dried sea cucumber. The specific working principle is as follows: Outdoor fresh air enters the shell 1 after being initially intercepted by the protective net 4 at the fresh air inlet 3 for large impurities (such as leaves and insects). At the same time, the air in the dry air drying workshop flows back into the shell 1 through the return air inlet 2 (the connection between the return air inlet 2 and the shell 1 is located between the primary filter 6 and the dehumidifier 7), and mixes with the fresh air to form the airflow to be treated, thereby improving the efficiency of air circulation and reducing the energy consumption of temperature and humidity control. The mixed airflow first flows through the primary filter element 6, which, as a coarse filter component, efficiently intercepts large particles (such as dust and hair) with a diameter of 5μm or more in the airflow, preventing large impurities from entering subsequent precision components and causing damage, thus laying the foundation for subsequent processing stages, and initially reducing the dust content in the airflow.
[0043] The airflow that has been preliminarily filtered enters the dehumidifier 7. The first frame 71 of the dehumidifier 7 provides support for the internal structure. Several inclined wall plates 72 are arranged from top to bottom on the inner side of the dehumidifier 72 and are inclined along the air inlet to outlet direction. An air guide cavity 73 is formed between adjacent inclined wall plates 72. The bottom of the inclined wall plate 72 and the top of the lower inclined wall plate 72 are on the same horizontal plane, ensuring that the airflow can fully contact the upper and lower surfaces of the inclined wall plate 72. Water vapor condenses on the surface of the inclined wall plate 72 to form condensation, which quickly reduces the humidity of the airflow and meets the low humidity requirements for drying the dry ingredients. Multiple fins 76 at the bottom of the inclined wall plate 72 are vertically arranged, and their lengths are successively shortened along the air inlet to air outlet direction. The bottom faces the top surface of the fins 76, forming a multi-barrier structure in the air guide cavity 73, which further increases the airflow contact area, enhances heat exchange and condensation effect, and improves dehumidification efficiency in high humidity environments. The condensation on the surface of the inclined wall plate 72 gathers along the inclined plate surface to the bottom end, and flows into the liquid guide pipe 74 through the liquid outlet 77 at the connection between the liquid guide pipe 74 and the inclined wall plate 72. Finally, it is collected in the liquid collection tank 75 connected to the bottom through the liquid guide pipe 74, realizing the directional and closed collection and discharge of condensate, avoiding the accumulation of liquid and the growth of microorganisms, and ensuring the hygiene and safety of the air supply.
[0044] After dehumidification, the airflow passes through the air distribution plate 8, which is a perforated mesh plate that can organize the uneven airflow into a uniform airflow, ensuring that the subsequent purification components can fully function across the entire cross-section. The uniform airflow enters the electronic dust collector 9, which uses the principle of high-voltage electrostatic adsorption to efficiently capture fine particulate matter such as PM2.5 and microbial aerosols in the airflow, completing the secondary purification. The airflow after electronic dust removal continues to flow through the secondary filter element 10. This fine filtration component can filter out ultrafine particles with a diameter of 0.3μm or larger (such as bacteria, viruses, and fine dust), achieving deep purification and ensuring that the cleanliness of the airflow meets the standards of food processing workshops, thus preventing the dried sea cucumber from being contaminated during the drying process.
[0045] Normal operating state: The electric cylinder 112 of the barrier seal 11 drives the uppermost drive rod 115. Adjacent drive rods 115 are connected by a hinge 117, which in turn drives each swing arm 116 to swing, causing the gate 113 in the second frame 111 to rotate around the axis to a horizontal state. An air passage opening is formed between adjacent gates 113, and the purified airflow can pass through smoothly. The side buckle shell 114 plays a protective and containment role for the drive rod 115 and the swing arm 116. Maintenance status: When it is necessary to replace or clean the primary filter element 6, electronic dust collector 9, or secondary filter element 10, the electric cylinder 112 is driven in reverse, which drives the gate 113 to flip to the upright position through the drive rod 115 and the swing arm 116. The adjacent gates 113 are connected and abut against each other, dividing the interior of the housing 1 into two independent cavities. This effectively blocks the dust and pollutants generated during the maintenance process from entering the subsequent clean air duct, avoiding the contamination of products caused by pollutants entering the dried sea cucumber drying workshop, and complying with food processing hygiene standards.
[0046] The clean airflow passing through the barrier enclosure 11 enters the noise reduction and silencing device 12. Several noise reduction units 14 are distributed on the frame of the device, and the fourth frame 141 of each noise reduction unit 14 provides support for the internal structure. After the airflow enters the hollow cavity of the fourth frame 141, it first contacts the inclined air guide plate 145 and is diverted to the upper cavity 146 and the lower cavity 147. The airflow is buffered by multiple reflections in the cavity, and the flow rate is regulated to reduce aerodynamic noise. The airflow is refracted to the perforated metal mesh 144, and the holes on its surface further disperse the airflow. At the same time, the noise generated during operation passes through the non-woven fabric layer 143 and is absorbed step by step by the outermost aluminum silicate layer 142, which greatly reduces the airflow noise and equipment vibration noise, achieving quiet operation and adapting to the working conditions of continuous production in the dry ginseng drying workshop around the clock.
[0047] The clean airflow after noise reduction enters the temperature and humidity control device 13. The heating unit and humidification unit are arranged sequentially in the third frame 131 of the device along the air inlet to air outlet direction, and the air supply parameters are precisely controlled to the optimal range for drying and locking in freshness of dried ginseng.
[0048] If the airflow temperature is too low or a low-temperature drying temperature needs to be maintained, multiple heating resistance wires 133 on the stand 132 of the heating unit are activated to precisely heat the airflow, stabilizing the airflow at a suitable temperature for low-temperature drying of dried sea cucumbers. This prevents excessively high temperatures from damaging the nutritional components of the sea cucumbers and achieves a freshness-locking effect. If the airflow humidity is too low, the atomizing nozzle 137 of the humidification unit is connected to a water source through a pipe and sprays water into the humidification cavity 136 formed by the first metal mesh 134 and the second metal mesh 135. When the airflow passes through the humidification cavity 136, it comes into full contact with the water mist, achieving precise humidity compensation. This prevents the sea cucumbers from cracking and losing nutrients due to excessively low ambient humidity, ensuring the quality of the dried sea cucumber product. The droplets splashed on the metal mesh flow along the wall into the water collection tank, preventing water from overflowing and breeding bacteria. After temperature and humidity regulation, the clean air that meets the requirements of the dried ginseng air-drying and freshness-locking process is finally delivered into the dried ginseng air-drying workshop through the protective net 4 at the air outlet 5, maintaining a stable, clean and suitable air-drying environment in the workshop and completing the entire air handling process.
