Description

Technical Field

[0001] This invention relates to the field of silkworm egg salt ratio technology, specifically to an integrated device for mulberry silkworm egg dispersion and salt ratio based on air flotation technology. Background Technology

[0002] Silkworm egg production is one of the most crucial steps in silkworm breeding. During production, factors such as mulberry leaf quality, rearing environment, seed production technology, and silkworm egg protection conditions can lead to the production of some defective eggs. These defective eggs are usually different in color from the inherent color of the variety, i.e., discolored eggs. The majority are yellow unfertilized eggs, commonly known as yellow eggs, but there are also red dead eggs, brown dead eggs, etc. These defective eggs generally cannot continue to develop and become dead eggs; in production, they are collectively referred to as defective eggs. To improve the quality of silkworm eggs during breeding, these defective eggs must be removed to ensure that the quality meets the production standards specified for the variety. Traditional egg selection methods include manual egg selection (commonly known as spot selection) and salt water gravity selection. Manual egg selection is too time-consuming, labor-intensive, and inefficient, and is only suitable for eliminating a very small number of defective eggs. The salt water gravity method is suitable for removing large quantities of defective eggs and is usually used after the silkworm eggs have been acid-soaked or during winter egg bathing. When selecting silkworm eggs by salt ratio, the eggs, after being soaked in acid and threshed or sterilized in a bath, need to be gently stirred into two salt solutions of different specific gravities (heavy ratio and light ratio). The eggs are then allowed to naturally separate into layers based on their density in the two solutions. The heavier eggs at the bottom and the lighter eggs at the top are removed, leaving only the good eggs in the middle layer. Current salt-gravity egg selection methods typically use a simple, easy-to-operate conical cylinder. While the equipment is simple, the operation is quite cumbersome, requiring not only a high level of technical experience from the operator but also significant manual labor. The preparation of the salt solution, the control of the heavy ratio, light ratio, and the difference between the light and heavy ratios, the re-selection of the eggs in the light layer, desalination, and dehydration are particularly challenging. Manual operation requires prolonged contact with the salt solution and high-intensity work in a low-temperature environment. Furthermore, the desalination and dehydration equipment, as well as the air-drying and sun-drying equipment, occupy considerable space, and there are numerous transfer steps. During air-drying, the silkworm eggs must be constantly and gently turned to accelerate the drying process. In summary, the current method of using salt ratio for loose silkworm eggs is too time-consuming and labor-intensive, and cannot meet the needs of high-quality development of the modern sericulture industry. Summary of the Invention

[0003] Technical problems to be solved To address the shortcomings of existing technologies, this invention provides an integrated device for mulberry silkworm egg distribution and salt ratio based on air flotation technology. This device not only optimizes the space occupied by multiple necessary equipment such as desalination, dehydration, air drying, and sun drying during salt ratio control, but also solves the problems of time-consuming and labor-intensive steps such as multiple high-intensity manual transfer between multiple devices and the need for continuous manual turning of silkworm eggs during air drying.

[0004] Technical solution To achieve the above objectives, the present invention provides the following technical solution: an integrated device for reducing the salt ratio of silkworm eggs based on air flotation technology, comprising a water tank, an inner water tank disposed within the water tank, and two conical inner cylinders with micropores on their side walls, and further comprising: A partition is fixed in the water tank to divide the water tank into a salt ratio chamber and a dehydration chamber. One of the conical inner cylinders is set in the salt ratio chamber and the other conical inner cylinder is set in the dehydration chamber. A first cover plate and a second cover plate are hinged to the opening at the upper end of the water tank. The turbulence mechanism is installed on the first cover plate and connected to a turbulence component extending into the conical inner cylinder. When the silkworm eggs are subjected to a light salt ratio, the water in the conical inner cylinder is stirred by the turbulence component rotating at low speed to form a vortex, which suspends the silkworm eggs in the water, separates the inferior seeds and impurities from the superior seeds, and the overflow formed by secondary water injection carries away the inferior seeds and impurities floating on the water surface. A drainage component is located at the bottom of the inner conical cylinder and is opened and closed quickly by electromagnetic thrust. It is used to drain the secondary salt that settles at the bottom of the cone after the heavy salt ratio is separated. The gas collecting hood is located at the bottom of the inner water tank and has an opening at the top to support the conical inner cylinder. It can also deliver suitable compressed gas into the conical inner cylinder. When the gas passes through the micropores and enters the conical inner cylinder, it forms small bubbles. As the bubbles rise, they encapsulate the silkworm eggs and help them float to the surface, thereby removing impurities. The dehydration component is installed in the dehydration chamber and can directly dehydrate the silkworm eggs in the conical inner cylinder. A turbulence component is also installed on the side wall of the second cover plate. The turbulence component can deliver compressed gas into the inner cylinder. The compressed gas passes through the dehydrated silkworm eggs from top to bottom using a through-flow path, thereby achieving further air drying of the silkworm eggs.

[0014] As a further description of the above technical solution, a window is provided on the front side of the water tank, the window connecting the salt ratio chamber and the dehydration chamber, and a glass panel is installed at the window to seal the dehydration chamber. The conical inner cylinder and the inner water tank are made of either polycarbonate or polymethyl methacrylate.

[0015] Beneficial effects Compared with the prior art, the present invention provides an integrated device for the salt ratio of silkworm eggs based on air flotation technology, which has the following beneficial effects: 1. Compared with traditional operations, this technical solution can greatly reduce the contact time with water and reduce labor intensity throughout the process, especially when the temperature is low. In particular, during the dehydration stage, compared with traditional dehydration and drying, the through-flow air drying can use airflow to force moisture removal without occupying much space, which greatly improves the dehydration speed.

[0016] 2. This technical solution adopts a combined conical inner cylinder and inner water tank. The silkworm eggs to be treated are directly placed in the conical inner cylinder. The water in the inner water tank can pass through the screen on the conical inner cylinder. At this time, the water level rises slowly from bottom to top, which will not cause impact on the silkworm eggs. When the water level rises to three-fifths of the inner cone, the turbulence component is submerged. During the soaking process, the first motor can be started to drive the first pulley to load the transmission belt. The load on the transmission belt drives the second pulley to rotate the hollow tube. At this time, the turbulence component can be used to stir the water at low speed, so that the water can form a vortex in the conical inner cylinder, so that the secondary seeds and impurities can be separated from the silkworm eggs and float on the water surface for easy cleaning and separation.

[0017] 3. During dehydration, the centrifugal force generated by rotation is used to expel the water between the silkworm eggs. After that, the machine is stopped, and compressed gas is delivered from the hollow shaft. The compressed gas passes through the turbulence assembly, causing the gas to be diverted into the conical inner cylinder. Due to the sealing of the sealing plate, the gas can only pass through the gaps between the silkworm eggs and be discharged from the outside. At this time, the airflow passes through the silkworm eggs piled up in the conical inner cylinder. In this way, the airflow can be used to accelerate the evaporation of moisture, thereby completing the air drying of the silkworm eggs. After air drying, the silkworm eggs can be further air-dried in the shade according to the actual humidity. Attached Figure Description

[0020] 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. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example: See attached document Figure 1-11 The integrated salt ratio device for silkworm egg dispersal based on air flotation technology includes a water tank 1, an inner water tank 6 disposed in the water tank 1, and two conical inner cylinders 21 with micropores on their side walls. The micropores on the conical inner cylinders 21 are further comprising: A partition 24 is fixed in the water tank 1, dividing the water tank 1 into a salt ratio chamber and a dehydration chamber. One conical inner cylinder 21 is set in the salt ratio chamber, and the other conical inner cylinder 21 is set in the dehydration chamber. A first cover plate 4 and a second cover plate 2 are hinged to the upper end of the water tank 1. A window is provided on the front side of the water tank 1, which connects the salt ratio chamber and the dehydration chamber. A glass panel 7 is installed at the window to seal the dehydration chamber. The conical inner cylinder 21 and the inner water tank 6 are made of either polycarbonate or polymethyl methacrylate. The transparent conical inner cylinder 21 and inner water tank 6 allow technicians to easily observe the buoyancy of silkworm eggs in the brine during processing. The glass panel 7 installed in the dehydration chamber can block the water splashed out during dehydration. To ensure the structural strength and transparency of the conical inner cylinder 21, holes with a diameter of 3 to 6 centimeters can be made in its conical sidewall. A 300-400 mesh screen can be fixed in the holes. Nylon or silk mesh can be selected. This ensures water permeability while preventing the silkworm eggs from being exposed. The water flow is from the outside to the inside, so the silkworm eggs will not be impacted by the excessive water injection speed, and the screen will not be blocked.

[0022] like Figures 2-6 As shown, the turbulence-inducing mechanism includes a hollow tube 5, which is rotatably connected to a first cover plate 4 via a sealed bearing. A first pulley 38 is fixedly connected to the side wall of the hollow tube 5, and a first motor 17 is fixedly connected to the side wall of the first cover plate 4. A second pulley 40 is fixedly connected to the output end of the first motor 17. A transmission belt 39 is wound around the first pulley 38 and the second pulley 40. A rotary joint is fixedly connected to the upper end of the hollow tube 5, through which water can be injected into the hollow tube 5. A turbulence-inducing assembly 18 is coaxially mounted on the lower end of the hollow tube 5. 8. The rotatable drain is used to clean the silkworm eggs in the conical inner cylinder 21. The turbulence assembly 18 includes a top plate 31 and a bottom plate 32. Multiple turbulence plates 30 are fixedly connected between the bottom plate 32 and the top plate 31. The cross-section of the turbulence plate 30 is V-shaped, and an exhaust hole 29 is provided at the bend. An arc-shaped guide part is provided inside the turbulence plate 30. A cylinder is provided at the lower end of the top plate 31. The bend of the turbulence plate 30 is fixedly connected to the side wall of the cylinder. An exhaust channel is formed between two adjacent turbulence plates 30. An assembly hole for connecting with the transmission component is provided at the center of the top plate 31.

[0023] This technical solution uses a combined conical inner cylinder 21 and inner water tank 6. The silkworm eggs to be treated are directly placed in the conical inner cylinder 21. The water in the inner water tank 6 can pass through the screen on the conical inner cylinder 21 and enter. At this time, the water level rises slowly from bottom to top, which will not cause impact on the silkworm eggs. When the water level rises to three-fifths of the inner cone, the turbulence component 18 is submerged. During the soaking process, the first motor 17 can be started to drive the first pulley 38 to force the transmission belt 39. The transmission belt 39 is forceful to drive the second pulley 40 to rotate the hollow tube 5. At this time, the turbulence component 18 can be used to stir the water at a low speed (50-80 revolutions per minute) so that the water can form a vortex in the conical inner cylinder 21, so that the secondary seeds and impurities can be separated from the silkworm eggs and float on the water surface for easy cleaning and separation.

[0024] The upper end of the conical inner cylinder 21 is provided with an outer rolled edge 28, and the upper end of the inner water tank 6 is provided with an inner rolled edge. A sealing gasket is embedded at the upper end of the inner rolled edge. A pressure ring 25 is fixedly connected to the lower end of the first cover plate 4. The lower end of the pressure ring 25 contacts the upper end of the conical inner cylinder 21, so that the outer rolled edge 28 presses the sealing gasket tightly. A rubber ring 20 is fixedly connected in the inner water tank 6. The conical inner cylinder 21 is interference-fitted into the rubber ring 20. A turbulence mechanism is installed on the first cover plate 4 and connected to a turbulence component 18 extending to the conical inner cylinder 21. When the silkworm eggs are subjected to a light salt ratio, the water in the conical inner cylinder 21 is stirred by the low-speed rotating turbulence component 18 to form a vortex, which suspends the silkworm eggs in the water, separates inferior seeds and impurities from superior seeds, and carries away the inferior seeds and impurities floating on the water surface by secondary water injection to form an overflow.

[0025] The drainage assembly includes a sleeve 34 with a sealed top. An isolation cover 22 is fitted onto the side wall of the sleeve 34. Two drainage ports are opened on the wall of the sleeve, and a guide sleeve is fitted into both drainage ports. The guide sleeve passes through the drainage ports and is fixed inside the isolation cover 22. A push rod 36 is fitted inside the guide sleeve. A spring 35 is fitted onto the wall of the push rod 36. One end of the spring 35 is fixedly connected to the inside of the sleeve 34, and the other end of the spring 35 is fixedly connected to one side of the guide sleeve. The upper end of the sleeve 34 is fitted into the push rod 36 through a round hole. The upper end of the push rod 36 passes through the round hole and is fixedly connected to the upper inner wall of the isolation cover 22. A strong magnet 37 is fixedly connected to the lower end of the push rod 36. A waterproof cover 23 is fixedly connected between the inner water tank 6 and the water trough 1. An electromagnet 33 is fixedly connected inside the waterproof cover 23.

[0026] When the salt ratio is adjusted, the secondary and superior seeds will form stratification at different settling speeds after being stirred and mixed in the concentrated brine. The secondary seed will settle faster and will settle in the cone-shaped inner cylinder 21 before the superior seed. After settling, the electromagnet 33 can be turned on to generate a magnetic pole with the same magnetic pole as one end of the strong magnetic block 37. The magnetic repulsion force generated at this time pushes the top rod 36 to move the isolation cover 22 upward in a straight line. At this time, the blocked drain outlet is exposed, and the water flow carries the secondary seed into the sleeve 34 and finally discharges into the inner water tank 6, and is discharged by the drain pipe installed on the inner water tank 6.

[0027] A gas collecting hood 45 is fixed inside the bottom of the inner water tank 6. The top of the gas collecting hood 45 has a conical hole that mates with the conical surface of the conical inner cylinder 21, and a rubber conical tube is fixedly connected inside the conical hole. The lower end of the gas collecting hood 45 has a round opening that mates with the sleeve 34. An air inlet pipe, a light brine pipe, a heavy brine pipe, a drain pipe, and a sewage pipe are fixedly connected to the water tank 1. One end of the air inlet pipe is fixed to the bottom of the inner water tank 6 and communicates with the inside of the gas collecting hood 45. One end of the light brine pipe, the heavy brine pipe, and the drain pipe... All ends are fixedly connected to the bottom of the inner water tank 6, the drain pipe is connected to the inside of the water tank 1, the drainage component is set at the bottom of the inner conical inner cylinder 21, and is opened and closed quickly by electromagnetic thrust, used to drain the secondary salt that settles at the bottom of the cone after the heavy salt ratio is separated. The outer side of the inner water tank 6 is fitted with a ring-shaped separation tank 19, and the bottom of the separation tank 19 is provided with a seepage plate, which is used to filter impurities and secondary salt in the overflow water. The side wall of the inner water tank 6 is provided with a ring-shaped protrusion 27 to limit the separation tank 19. The gas collecting hood 45 is located at the bottom of the inner water tank 6 and has an opening at the top to support the conical inner cylinder 21. It can also deliver compressed gas into the conical inner cylinder 21. When the gas passes through the micropores and enters the conical inner cylinder 21, it forms small bubbles. During the process of the bubbles rising, they wrap the silkworm eggs and make them float to the surface, thereby removing impurities by making the bubbles float to the surface. like Figure 12 This is a simplified diagram of the control console, water circuit, electrical circuit, and air circuit of this technical solution. It can be configured appropriately according to the needs in actual application. The air inlet pipe, light brine pipe, heavy brine pipe, drain pipe, and sewage pipe are all equipped with electrically controlled water valves, which are controlled by the control panel. Water is supplied by an independent diaphragm pump, including the air pump system for the air source. Existing technology can be used, so it will not be described in detail here.

[0028] Figure 13 This is a simplified diagram showing the distribution of holes and screens when the conical inner cylinder 21 is unfolded into a plane. The diameter of the holes and the mesh size of the screen can be adjusted and adapted according to requirements.

[0029] This technical solution uses a hinged first cover plate 4. When fastened, the pressure ring 25 on the first cover plate 4 can press against the upper end of the conical inner cylinder 21, so that the inner rolled edge and the outer rolled edge 28 together press the sealing gasket to achieve a seal. At the same time, the lower end is pressed against the rubber ring 20, so that the hole opened at the lower end of the conical inner cylinder 21 is inside the gas collection hood 45. At this time, the air inlet pipe installed at the lower end can directly deliver the compressed air to the gas collection hood 45. At this time, the compressed gas can pass through the screen to form small bubbles that float in the water inside the conical inner cylinder 21. During the floating process, it can effectively wrap the lighter impurities and inferior seeds and float to the water surface. In this way, the air flotation effect can be formed to improve the efficiency of removing impurities from silkworm seeds with a light salt ratio. After the gas floats up, it is discharged from the exhaust port on one side of the first cover plate 4.

[0030] like Figure 2 and Figure 9 The dehydration assembly shown includes a first housing 42, which is fixed to the bottom of the water tank 1. The upper end of the housing is rotatably connected to a conduit 43 via a sealed bearing. The wall of the conduit 43 is rotatably connected to a second housing 41 via a sealed bearing. The upper end of the second housing 41 has a through hole that matches the bottom of the conical inner cylinder 21. A rubber gasket 44 is fixedly connected to the through hole. Multiple supports 11 are fixedly connected to the upper end of the second housing 41. A ring 12 is fixedly connected to the upper end of each support 11. The ring 12 is fitted onto the side wall of the conical inner cylinder 21. An auxiliary air pipe is fixedly connected to the lower end of the first housing 42. A toothed ring 10 is fixedly connected to the side wall of the second housing 41. A gear 9 meshes with one side of the toothed ring 10. A second motor 8 is fixedly connected to the lower end of the water tank 1. The output end of the second motor 8 is fixedly connected to the lower end of the gear 9. A hollow shaft 3 is fixedly connected to the side wall of the second cover plate 2. A sealing plate 16 is rotatably connected to the shaft wall of the hollow shaft 3 through a sealing bearing. An elastic sealing part that cooperates with the inner side of the conical inner cylinder 21 is provided at the edge of the sealing plate 16. A limiting ring 26 that cooperates with the elastic sealing part is provided on the side wall of the conical inner cylinder 21. The lower end of the hollow shaft 3 extends to the bottom of the sealing plate 16 and is fixedly connected to the upper end of the turbulence assembly 18.

[0031] A positioning ring 13 is fixedly connected inside the dehydration chamber. Multiple rubber rollers 14 are fixedly connected to the inner side of the positioning ring 13. The rubber rollers 14 contact the side wall of the conical inner cylinder 21. A positioning part is provided on the inner side of the conical inner cylinder 21, and the positioning part contacts the elastic sealing part on the sealing plate 16. A return water pipe is fixedly connected to the bottom of the water tank 1. Exhaust vents are provided at the edges of both the first cover plate 4 and the second cover plate 2. Two positioning rollers 15 are fixedly connected to the lower end of the second cover plate 2, and both positioning rollers 15 contact the upper end of the conical inner cylinder 21. The dehydration assembly is installed in the dehydration chamber and can directly dehydrate the silkworm eggs in the conical inner cylinder 21. A turbulence-inducing component 18 is also installed on the side wall of the second cover plate 2, which can guide the flow into the inner cylinder. Compressed gas is supplied and flows through the dehydrated silkworm eggs from top to bottom via a cross-flow path, further drying the eggs. Under static pressure, the cross-flow drying technology allows for precise control of air temperature, air speed, and drying time. Because silkworm eggs are relatively fragile, a "low temperature, high air volume" mode can be used (e.g., using drying air slightly above room temperature). This rapidly dehydrates the eggs while avoiding heat stress damage to the embryos. In addition, the cross-flow drying technology ensures high consistency, with each batch of silkworm eggs dried under identical conditions, facilitating quality management and traceability. It also avoids mechanical friction or compression of the silkworm eggs during repeated drying and harvesting, protecting the integrity of the eggs.

[0032] During dehydration, the conical inner cylinder 21 is installed between the positioning ring 13 and the circular ring 12 and pressed by the second cover plate 2. The conical inner cylinder 21 can be positioned by the rubber roller 14 to improve the stability during rotation. During dehydration, the centrifugal force generated by rotation is used to discharge the water between the silkworm eggs. After that, the machine is stopped and compressed gas is delivered from the hollow shaft 3. The compressed gas passes through the turbulence assembly, so that the gas is diverted and discharged into the conical inner cylinder 21. Due to the sealing of the sealing plate 16, the gas can only pass through the gaps between the silkworm eggs. At this time, the airflow passes through the silkworm eggs piled in the conical inner cylinder 21. In this way, the flow of air can be used to accelerate the evaporation of water, thereby completing the air drying of the silkworm eggs. After air drying, the silkworm eggs can be further air-dried in the shade according to the actual humidity.

[0033] In the above technical solution, compared with the traditional salt ratio equipment (conical barrel), which requires manual contact with water at each step, including adding water, stirring, removing impurities, salt ratio, washing and draining, and drying, this technical solution simplifies the operation steps of the traditional salt ratio. The soaking, washing, removing impurities, light salt ratio, heavy salt ratio, water washing, dehydration and air drying can be completed by manual operation of the equipment. Compared with the traditional equipment, this technical solution does not require long-term contact with the salt ratio water or high-intensity transfer work between multiple devices. Moreover, the impurities separated during the light salt ratio can be quickly discharged by using air flotation combined with overflow. The secondary seeds separated during the heavy salt ratio can also be easily discharged. The remaining two types are left in the conical inner barrel 21. The conical inner barrel 21 can be directly placed into the dehydration chamber for dehydration and air drying. At this time, the salt ratio chamber can continue the salt ratio operation, thereby accelerating the salt ratio efficiency of silkworm eggs.

[0034] The operating instructions for this technical solution are as follows: 1. Place the silkworm eggs into the conical inner tube 21, ensuring that the eggs are flattened and do not exceed half the height of the inner tube 21. Finally, cover the tube with the first cover plate 4 and lock it in place.

[0035] 2. Inject a light salt solution, ensuring the liquid level does not exceed four-fifths of the conical inner cylinder 21. The specific gravity of the light salt solution should be between 1.075 and 1.080, with a salt concentration of approximately 10% to 11%. Use a turbulence-inducing component to stir at a low speed, and combine this with gas flotation to suspend the silkworm eggs in the mixture. After stopping the stirring and allowing the silkworm eggs to sink, the floating material consists of unfertilized eggs, dead eggs, and other waste. Continue injecting the light salt solution into the inner water tank 6 until it overflows from the top of the conical inner cylinder 21. At this point, the waste can be directly discharged.

[0036] 3. Open the electric control valve on the drain pipe to drain the light salt ratio solution in the inner water tank 6. After the light salt ratio solution is filtered to remove impurities, it is discharged into the recycling tank. Since its concentration does not change, it can be recycled to reduce the waste of salt ratio solution. After draining, the silkworm eggs in the conical inner cylinder 21 can be rinsed with running clean water, or the water can be drained for a certain period of time before adding heavy salt ratio solution.

[0037] 4. Add the heavy salt solution and control the liquid level. The specific gravity of the heavy salt solution is in the range of 1.090 - 1.095, and the salt concentration is about 14%-15%. Use the turbulence component to stir at low speed and use gas to achieve air flotation, so that the silkworm eggs are suspended in the mixture. After stopping the stirring, the silkworm eggs will sink and separate into layers. The upper layer is full, healthy, and high-quality eggs, while the lower layer is inferior eggs.

[0038] 5. Discharge the lower layer of eggs. This process requires manual observation of the discharge. When the drainage component is turned on, the water flow pushes the lower layer of inferior eggs out of the drainage component. You can observe the color of the silkworm eggs (the lower layer is light yellow unfertilized eggs, and the upper layer is gray-green superior eggs). After the lower layer of inferior eggs is discharged, turn off the drainage component. At this time, the silkworm eggs in the conical inner cylinder are the required superior eggs.

[0039] 6. Open the electric control valve on the drain pipe to drain the heavy salt solution in the inner water tank 6. After the heavy salt solution is filtered to remove impurities, it is discharged into the recovery tank. Since its concentration does not change, it can be recycled to reduce the waste of salt solution. After draining the salt solution, the silkworm eggs in the conical inner cylinder 21 can be rinsed with running clean water. After the liquid level rises, the turbulence component can be used to turn the liquid over for desalination. The desalination time is not less than 7 minutes until there is no salty taste. 7. Directly remove the conical inner cylinder 21 and place it on the dehydration assembly. Use the dehydration assembly to centrifuge and dehydrate the desalted silkworm eggs. Control the dehydration speed below 3000 rpm and maintain dehydration for 7 minutes. After stopping the rotation, directly send gas through the turbulence assembly into the conical inner cylinder 21. At this time, use the fast-flowing airflow for through-flow drying. The drying time can correspond to the time required for the salt ratio. That is, after the next batch of silkworm eggs is selected for salt ratio, the drying can be stopped and the degree of dryness can be observed. A second air-drying treatment can be carried out separately as required. In this way, continuous silkworm egg salt ratio selection can be achieved, and the speed of large-scale silkworm egg salt ratio can be accelerated.

[0040] When using this technical solution, the salt ratio solution can be quickly discharged during the salt ratio stage, and the salt ratio solution can be reused after filtration and reflux, reducing the waste of the salt ratio solution. In addition, a simple rinse with clean water can be used for light salt ratio to avoid affecting the concentration during heavy salt ratio.

[0041] During the desalination stage, a large amount of flowing clean water can be directly generated for rinsing, thereby improving the desalination efficiency. In the dehydration stage, water can be directly drained, centrifuged, or flow-through air-drying. The dehydration speed is fast and does not require manual turning. The time can be matched with the salt ratio and desalination speed, which speeds up the entire process.

[0042] Compared to traditional methods, the above process significantly reduces the time users spend in contact with water, especially at lower temperatures, thus lowering labor intensity. Particularly during the dehydration stage, unlike traditional dehydration and air drying, the through-flow drying method utilizes a suitable and safe airflow to forcefully remove moisture without occupying much space, greatly improving the dehydration speed. The through-flow drying method ensures that every silkworm egg and every angle is evenly and gently circulated by air, avoiding localized over-drying or dampness. Uniform drying provides the most suitable dehydration environment for all silkworm embryos, effectively improving the hatching rate and uniformity of silkworm eggs.
