Description

Technical Field

[0001] This invention belongs to the field of disinfection technology in the aquaculture industry, specifically relating to a high-temperature dual-airflow circulating disinfection room for chicken farms and its disinfection method. Background Technology

[0002] A sterilization room is a specialized device for the unified indoor high-temperature sterilization of chicken farm equipment, such as chicken cages. Its purpose is to effectively kill bacteria and viruses through high-temperature sterilization, ensuring the cleanliness of the equipment and the health of the animals. Sterilization rooms typically employ a sealed structure with excellent insulation and airtightness, ensuring the effectiveness and safety of high-temperature sterilization. Inside, they are usually equipped with heating and sterilization devices. The heating device raises the room temperature to the required sterilization level, and other sterilization devices can also be installed, such as high-temperature steam or ultraviolet light, for comprehensive sterilization of the chicken farm equipment.

[0003] While using high temperatures in conjunction with other disinfection equipment can improve disinfection efficiency, chicken farm equipment can also be effectively disinfected by baking at around 65°C for 30 minutes at a lower cost. However, the heating methods in existing disinfection rooms are quite complex, and most use ground-level heating. This requires a large room volume to prevent the heating equipment from obstructing the movement of items to be disinfected. Furthermore, to ensure rapid temperature rise, the temperature near the heating equipment is significantly higher than the maximum temperature that many pieces of equipment can withstand, potentially causing structural deformation during disinfection. Summary of the Invention

[0004] To address the problems existing in the prior art, this invention provides a high-temperature dual-airflow circulating disinfection room for chicken farms and its disinfection method. The aim is to achieve efficient and low-cost high-temperature disinfection through a new and simple structural design, while also avoiding damage to the equipment.

[0005] The technical solution adopted in this invention is as follows:

[0006] In a first aspect, the present invention provides a high-temperature dual-airflow circulating disinfection room for chicken farms, comprising a room body having at least two entrances and exits, through which two entrances and exits symmetrically arranged along the length of the room body are used to transfer or move items to be disinfected into the room body, and a support frame is provided on the top of the room body near the entrances and exits, and several fans are provided on the support frame.

[0007] The air outlet of the fan blows air horizontally towards the top of the building, and the symmetrically arranged fans blow air towards each other.

[0008] A heating wire is installed at the air outlet of the fan. The air blown out by the fan converges at the middle of the top of the room and fills the room downward to raise the temperature.

[0009] The control module controls the temperature of the heating wire and / or the power of the fan according to the temperature sensor installed inside the chamber, thereby heating the temperature inside the chamber to 65°C and maintaining it for disinfection.

[0010] It should be noted that the "entry and exit doors" only define the two closable door structures at the two openings of the room, without specifying which direction is the inlet or outlet. That is, the entire room can be functionally defined as needed. Since the internal structure is symmetrically arranged with the two entry and exit doors, in actual use, the effect achieved by entering or exiting from either direction is the same. However, once the entry and exit directions are defined, the material flow remains unidirectional and will not be changed. Theoretically, the inlet side may have a higher contaminant concentration, while the outlet can directly connect to a higher-specification, low-contaminant channel. The above only describes the usage requirements in industry standards and does not limit the specific structure defined.

[0011] In conjunction with the first aspect, the present invention provides a first embodiment of the first aspect, wherein the support frame is a frame structure fixed to the inner wall of the top of the room and has a plurality of equally spaced hollow positions, and the fan is installed in the hollow positions.

[0012] In conjunction with the first aspect, the present invention provides a second embodiment of the first aspect, wherein the support frame is provided with a first bracket extending in the wind direction at the air outlet of the fan, and the end of the first bracket has a heating wire on the air duct, and the heating wires on the same support frame are connected in parallel by a control module to form a power supply circuit.

[0013] In conjunction with the first aspect, the present invention provides a third embodiment of the first aspect, wherein the support frame is provided with a second bracket extending in the wind direction at the air outlet of the fan, and a temperature sensor is provided at the end of the second bracket.

[0014] In conjunction with the first aspect, the present invention provides a fourth embodiment of the first aspect, wherein the object to be disinfected is one or more of chicken cages, egg racks and egg trays, and the object to be disinfected is stacked on the ground inside the house.

[0015] In conjunction with the first aspect, the present invention provides a fifth embodiment of the first aspect, wherein the fan is an axial flow fan.

[0016] In conjunction with the first aspect, the present invention provides a sixth embodiment of the first aspect, wherein an air guide plate is provided along the center line of the top of the room body perpendicular to the air outlet direction of the two side fans, the air guide plate has symmetrical guide arc surfaces facing the two side fans, and the air blown out from the two side fans is reversed by the guide arc surfaces and obliquely downward to the entrance and exit on the corresponding side.

[0017] The air guide plate has air guide holes with an opening area between 20-30% on both sides of the air guide arc surface, and the other side of the air guide hole faces the floor of the room.

[0018] The housing has an air inlet corresponding to each fan at the air inlet of each fan, and the air inlet is covered with a valve that is controlled to open and close by a control module.

[0019] Secondly, the present invention also provides a disinfection method, which uses the high-temperature disinfection chamber described above for disinfection. First, the temperature inside the chamber is controlled by the control module to not exceed 40 degrees Celsius. The items to be disinfected are placed inside the chamber through the entrance door, which serves as the inlet, using a trolley. The entrance doors on both sides are then closed. The control module controls the operation of the fan and heating wire, and the temperature of the air coming out of the heating wire is controlled by the temperature sensor to be between 65°C and 71°C. After the temperature inside the chamber rises to 65°C, this temperature is maintained for continuous heating and disinfection for 30 minutes. After the temperature inside the chamber cools down, the items to be disinfected are removed and the next batch of items to be disinfected is disinfected.

[0020] In conjunction with the second aspect, the present invention provides a first embodiment of the second aspect, which divides the floor inside the room into several areas, and determines a first disinfection area on the floor with the center line of the room perpendicular to the air outlet direction of the two side fans, and then sets the area near the entrance and exit on both sides as the second disinfection area. During disinfection, the items to be disinfected are first piled in the first disinfection area, and when the number of piled items exceeds the maximum capacity of the first disinfection area, they are placed in the second disinfection area.

[0021] Thirdly, the present invention also provides a disinfection method, which uses the high-temperature disinfection room in the sixth embodiment of the first aspect above for disinfection. First, the temperature inside the room is controlled by the control module to not exceed 40 degrees. After the object to be disinfected is placed in the room through the entrance and exit of the trolley, the air inlet and the entrance and exit on both sides are closed. Then, the fan and heating wire are controlled by the control module, and the temperature of the air coming out of the heating wire is controlled between 65°C and 71°C according to the temperature sensor. After the temperature inside the room rises to 65°C, the temperature is maintained for continuous heating and disinfection for 30 minutes.

[0022] Then open at least one side of the entrance / exit and both sides of the air inlets, turn off the heating element, but maintain or increase the fan power to blow the cold air entering from the air inlets to the air guide plate for rapid cooling. Replace the items to be disinfected when the temperature inside the room is below 40°C.

[0023] The beneficial effects of this invention are as follows:

[0024] (1) This invention optimizes and improves the position and setting of the heating equipment in the disinfection room. By using the upper circulating heating method, it avoids the high temperature air at the air outlet from directly contacting the equipment on the ground and causing the equipment to be damaged by heat. It is also applicable to the production line disinfection where equipment needs to be replaced frequently. The heating equipment at the top facilitates the transportation and transfer of materials on the ground. The through-channel design can improve efficiency.

[0025] (2) The present invention also arranges the optimal heat-disinfection position by injecting hot circulating air downward in the middle of the structure, thereby improving the disinfection efficiency and reducing energy consumption in each batch of different quantities of items to be disinfected.

[0026] (3) The present invention also improves the uniformity of temperature change in the entire chamber during heating by using the air guide plate structure. At the same time, it can cool the material transfer during cooling by continuously blowing air towards the inlet and outlet of the fan. Combined with the openable and closable air inlet, it can quickly cool the chamber, thereby reducing the cooling waiting time and improving efficiency. Attached Figure Description

[0045] Example 1:

[0046] This embodiment discloses a high-temperature dual-duct circulating disinfection room for chicken farms. This high-temperature disinfection room primarily uses heating equipment to raise the indoor temperature to approximately 65°C, thereby circulating and heating the items to be disinfected upon entering the room for disinfection. (Refer to...) Figure 2 The system includes a chamber 1 with at least two entrances 2. The two entrances 2 are symmetrically arranged along the length of the chamber 1 to allow or transfer items to be disinfected into the chamber 1. A support frame 5 is provided on the top of the chamber 1 near the entrances 2, and several fans 4 are provided on the support frame 5. The air outlets of the fans 4 blow air horizontally towards the top of the chamber 1, and the symmetrically arranged fans 4 blow air towards each other. A heating wire 9 is provided at the air outlet of the fan 4. The air blown from the fan 4 converges at the middle of the top of the chamber 1 and fills the chamber 1 downwards to raise the temperature. The temperature of the heating wire 9 and / or the power of the fans 4 are controlled by a control module according to the temperature sensor 8 installed in the chamber 1 to control the temperature of the chamber 1 to 65°C and maintain it for disinfection.

[0047] This embodiment also provides a disinfection control method. Based on the high-temperature disinfection room described above, the temperature inside the room 1 is first controlled by the control module to not exceed 40 degrees Celsius. The items to be disinfected are placed inside the room 1 through the entrance door 2 using a trolley. The entrance doors 2 on both sides are then closed. The control module then controls the operation of the fan 4 and the heating wire 9. The temperature of the air coming out of the heating wire 9 is controlled between 65°C and 71°C according to the temperature sensor 8. After the temperature inside the room 1 rises to 65°C, this temperature is maintained for continuous heating and disinfection for 30 minutes. After the temperature inside the room 1 cools down, the items to be disinfected are removed and the next batch of items to be disinfected is disinfected.

[0048] According to the air circulation direction inside the room 1, the ground inside the room 1 is divided into several areas. The first disinfection area is determined on the ground with the center line of the room 1 perpendicular to the air outlet direction of the two side fans 4. Then, the area near the entrances and exits 2 on both sides is set as the second disinfection area. During disinfection, the items to be disinfected are first piled in the first disinfection area. When the number of items piled exceeds the maximum capacity of the first disinfection area, they are placed in the second disinfection area.

[0049] Specifically, refer to Figures 1-4The first embodiment of a high-temperature dual-duct circulating disinfection room for chicken farms is provided, wherein the support frame 5 is a frame structure fixed to the inner wall of the top of the room body 1, and has several equally spaced hollow positions, and the fan 4 is installed in the hollow positions:

[0050] This design further enhances the stability and reliability of the entire structure. The support frame 5 is fixed to the inner wall of the top of the chamber 1, ensuring overall robustness and preventing deformation or displacement due to heavy loads or frequent use. The evenly spaced perforations not only provide installation locations for the fans 4 but also ensure their ventilation and heating efficiency. Installing one fan 4 in each perforation results in more uniform airflow and a more reasonable temperature distribution throughout the chamber 1.

[0051] To improve insulation, the walls of room 1 will be constructed with 240mm thick porous insulating bricks, while the roof will be made of 10cm thick double-sided sandwich corrugated steel panels, and the ceiling will be made of fire-resistant boards. This serves two purposes: insulation (reducing heat loss) and reducing the fire hazard that ordinary insulation boards might pose due to excessive heat.

[0052] The support frame 5 has a first bracket 6 extending in the airflow direction at the air outlet of the fan 4. The end of the first bracket 6 has a heating wire 9 positioned on the air duct. The heating wires 9 on the same support frame 5 are connected in parallel by a control module. The first bracket 6 cleverly positions the heating wire 9 at the air duct outlet, ensuring that the airflow can fully absorb heat as it passes through the heating wire 9, thus improving heat exchange efficiency. Simultaneously, the control module supplies power to the heating wires 9 on the same support frame 5 through the parallel power supply circuit, making the operation of the heating wire 9 more stable and preventing malfunctions of the entire support frame 5 due to a single heating wire 9 failure.

[0053] The support frame 5 has a second bracket 7 extending in the airflow direction at the air outlet of the fan 4. A temperature sensor 8 is installed at the end of the second bracket 7. The temperature sensor 8 on the second bracket 7 can monitor the temperature of the airflow after passing through the heating wire 9 in real time and transmit the temperature signal to the control module. This design not only improves the accuracy of temperature monitoring, but also provides the control module with more timely and reliable temperature data, enabling it to more intelligently adjust the temperature of the heating wire 9 and the power of the fan 4.

[0054] In this embodiment, the object to be disinfected is a chicken cage, but egg cartons or egg trays can also be disinfected; this embodiment only describes chicken cages. The chicken cages are stacked on the floor inside chamber 1: This design takes into account the actual usage scenarios of the chicken cages and the convenience of disinfection. Stacking not only saves space but also makes the disinfection process more efficient. The floor inside chamber 1 is specially treated, possessing good anti-slip and wear-resistant properties, ensuring the stability and safety of the chicken cages during the disinfection process.

[0055] The fan 4 is an axial flow fan, which has high ventilation efficiency and a large air volume. It can quickly blow out a large volume of hot air in a straight line. In conjunction with the heating wire 9 located at its air outlet, the air is quickly heated and concentrated at the top centerline of the chamber 1, filling the entire chamber 1. Taking advantage of the upward movement of hot air, it can first converge at the top and then continue to move downward, thus preventing excessively hot circulating air from directly contacting the chicken cages. At the same time, the axial flow fan 4 has a compact structure, is lightweight, and operates stably, which can meet the long-term, high-intensity working requirements of the high-temperature disinfection chamber.

[0056] In the disinfection room structure described above, the fans 4 on both sides are positioned opposite each other, forming a counter-flowing air duct at the top. Heated air first fills the top of the entire room 1, and then gradually expels or circulates downwards to heat the air. This heating method helps prevent the high-temperature air from directly contacting the items to be disinfected, thus allowing for a more uniform temperature rise within the room 1.

[0057] However, after disinfection, when cooling and transferring materials are required, the entrance door 2, which serves as the exit, is usually opened, and then the temperature is allowed to drop naturally to around 40 degrees Celsius before personnel can enter the room 1 to transfer materials.

[0058] To improve transfer efficiency, this embodiment also provides a disinfection room, as described above. Figures 5-8 The fixing positions of the entire chamber 1 and the fans 4 are the same as in the above-described embodiment. However, on the two side walls of the chamber 1 where the entrance and exit 2 are located, there are air inlets 3 corresponding to the internal fans 4. Each fan 4 corresponds to one air inlet 3, and a coverable, sealable valve is provided on the air inlet 3. The valve has multiple operating modes, all controlled by the control module. When heating is required, the air inlet 3 is closed. When cooling is required, one or both air inlets 3 are opened, the heating wire 9 is turned off, and the fans 4 are continuously turned on to continuously inject cold air from outside into the chamber 1 to accelerate the cooling efficiency.

[0059] Furthermore, an air guide plate 10 is provided along the centerline of the top of the room 1, perpendicular to the air outlet direction of the two side fans 4. The air guide plate 10 has symmetrical guide arc surfaces facing the two side fans 4. The air blown out from the two side fans 4 is redirected by the guide arc surfaces and obliquely downwards to the corresponding entrance and exit 2. The air guide plate 10 has guide holes with an opening area between 20-30% on both sides of the guide arc surfaces. The other side of the guide hole opens towards the ground of the room 1.

[0060] In addition, based on the above embodiments, a disinfection method using this high-temperature disinfection chamber is also provided:

[0061] First, the temperature inside chamber 1 is controlled below 40℃ using the control module. This step is to ensure that the items to be disinfected are not subjected to excessively high temperatures in the initial stage.

[0062] The items to be disinfected are transported into the room 1 via the entrance 2 (which serves as the entrance) using a trolley and placed properly. Then, the air inlet 3 and the entrance 2 are closed.

[0063] The control module activates fan 4 and heating wire 9. Based on real-time monitoring data from temperature sensor 8, the control module precisely adjusts the power of heating wire 9 to maintain the air temperature passing through it between 65℃ and 71℃. When the temperature inside chamber 1 reaches 65℃, the system maintains this temperature and continues the disinfection process for 30 minutes.

[0064] After the disinfection process is completed, the control module will sequentially open the entrance doors 2 and air inlets 3 on both sides, while simultaneously turning off the heating element 9. At this time, the fan 4 continues to operate at high power, drawing outside cold air into the chamber 1 through the air inlet 3 and rapidly cooling it through the air guide plate 10.

[0065] When the temperature inside room 1 drops below 40℃, the items to be disinfected can be replaced.

[0066] To verify the differences in heat disinfection in different areas, this embodiment provides a test method for comparative testing. The test primarily evaluates the bactericidal ability against Salmonella, Escherichia coli, Staphylococcus aureus, and mold under a set temperature of 65℃ for 30 minutes. The test method is as follows:

[0067] 1. Using purchased standard Escherichia coli, Salmonella, and Staphylococcus aureus, incubate them in MH broth at 37°C on a shaker at 180 rpm for 4 hours. Determine the concentration using a 0.5 McFarland turbidimetric tube and prepare a 10⁻¹⁰ solution. 6 The standard bacterial solution with cfu / ml was used as the stock solution.

[0068] The bacterial solution was diluted to a total of 6 concentrations: stock solution, 10⁻¹, 10⁻², 10⁻³, 10⁻⁴, and 10⁻⁵.

[0069] 2. Using a pipette, add 100 μL of bacterial suspension at different dilutions to plates (ordinary nutrient agar, MacConkey medium, or mannitol medium), and then spread evenly using a spreader. Prepare a control group and an experimental group for each dilution. After spreading, incubate the control group at 37°C for 48 hours, and count the bacterial cells.

[0070] (1) Control group: After the plates were coated with bacterial solutions of different dilutions, they were directly placed in the incubator for culture. All three types of bacterial solutions were cultured at 37°C for 48 hours.

[0071] (2) Experimental group: After the plates were coated with bacterial solutions of different dilutions, they were placed in a high-temperature room for simultaneous disinfection. The temperature was set at 65℃ and the time was 30min.

[0072] 3. Experimental Treatment: To test the effects of different locations in the high-temperature chamber, five sites were selected (front, middle, and rear), numbered 1-5. Site 5 was designated as the first area, while sites 1-4 were designated as the second area, located near different entrances / exits 2. Since the fans 4 were arranged side-by-side, the airflow towards the first area was evenly distributed along the centerline, thus the first area along the centerline had a certain width. Three different dilution plates were placed at each site, and all plates were individually placed upside down in the second layer of chicken coops from the floor.

[0073] 4. Place the items to be disinfected in a high-temperature room and perform high-temperature disinfection simultaneously. After disinfection, collect the plates immediately when the temperature drops from 70.8℃ to 49℃, place them in a constant temperature incubator at 37℃ for 48 hours, and then count them.

[0074] The test results are as follows:

[0075] Comparison photos of test results at site 1 (see reference) Figure 8-10 The first row of all images represents the control group, and the second row represents the high-temperature group.

[0076]

[0077] Results: Killing ability at site 1: MacConkey > Pripine > Mannitol.

[0078] The test results for points 2-5 are as follows:

[0079]

[0080] Killing ability at site 2: McConkey > Prudential > Mannitol.

[0081]

[0082] Killing ability at site 3: McConkey > Prudential > Mannitol.

[0083]

[0084] Killing ability at site 4: McConkey > Prudential > Mannitol.

[0085]

[0086] Killing ability at site 5: McConkey > Prufenoxanol > Mannitol.

[0087] Then, for each location, the effects of heating for 30 minutes and 1 hour were tested, as follows:

[0088]

[0089] This indicates that, under the temperature and time conditions set in the high-temperature chamber, the data on the killing ability of different dilutions of the coated plates at different sites showed that the killing ability was in the following order: MacConkey > Pripine > Mannitol.

[0090] It has the best killing ability against MacConkey indicator bacteria (Salmonella, Escherichia coli) and a relatively poor killing ability against mannitol indicator bacteria (Staphylococcus aureus), but still has a significant killing effect.

[0091] Site 5 exhibits the strongest overall bactericidal ability, while site 4 shows relatively weaker overall bactericidal ability. The order of bactericidal ability from strongest to weakest is: site 5, site 1, site 3, site 2, and site 4.

[0092] High-temperature disinfection for 30 minutes is generally more effective than high-temperature disinfection for 1 hour. High-temperature disinfection for 30 minutes already has a good killing effect, so there is no need to extend the disinfection time.

[0093] This invention is not limited to the optional embodiments described above, and anyone can derive other various forms of products based on the inspiration of this invention. The specific embodiments described above should not be construed as limiting the scope of protection of this invention; the scope of protection of this invention should be determined by the claims, and the specification can be used to interpret the claims.
