Description

TECHNICAL FIELD

[0001] The utility model relates to a tremella drying temperature intelligent regulation and control technical field, concretely is a tremella drying temperature intelligent regulation and control equipment. BACKGROUND

[0002] The limitations of traditional drying techniques, temperature control is rough: in traditional drying methods, such as natural drying, simple drying room drying, etc., temperature control is a major problem. Natural drying completely depends on the weather and environmental temperature, and cannot effectively control the temperature. Although the simple drying room has certain heating measures, it is often through simple on-off control of the heating equipment, and it is difficult to accurately adjust the temperature. For example, in the drying process of tremella, the traditional drying room can only roughly control the temperature in a wide range, which will lead to unstable drying quality of tremella, because the best drying temperature required by tremella is different at different stages. Uneven drying: traditional drying methods are prone to uneven drying. Taking natural drying as an example, tremella is placed in an open environment, and the angle and intensity of sunlight are different, resulting in a large difference in drying speed of different parts of tremella. Even in the drying room, due to uneven distribution of hot air, the part of tremella close to the heat source dries quickly, while the part far from the heat source dries slowly, affecting the overall quality of tremella. Low drying efficiency: the drying speed of traditional drying techniques is usually slow. Natural drying is limited by weather conditions and needs a long time to make tremella reach the ideal drying degree. Moreover, in high humidity weather or at night, tremella may absorb moisture in the air, prolonging the drying cycle. Due to the low heating efficiency and poor ventilation of the simple drying room, it is also unable to quickly and effectively dry tremella, which will seriously affect the production efficiency in large-scale production.

[0003] The existing technology patent document with publication number CN 216644883 U provides an intelligent temperature regulation and control device for grain drying machine, which comprises a drying chamber, an exhaust duct, a temperature sensor, a mixing chamber, a cold air duct, a hot air duct and a regulation and control mechanism. One end of the drying chamber is provided with an exhaust duct, and the other end of the exhaust duct is connected with a mixing chamber.

[0004] However, the existing device cannot accurately control the drying temperature when in use, causing the loss of nutritional ingredients and the deterioration of color of tremella due to too high temperature, or mildew caused by too low temperature. INVENTION CONTENTS

[0011] Preferably, the main body mechanism further includes tray and net rack, the tray is fixedly installed in the inside of drying chamber, and the net rack is fixedly installed in the inside of drying chamber.

[0012] Preferably, the regulation and control mechanism further includes control panel and waveguide, the control panel is fixedly installed on one side of the front end of regulation and control box, and the waveguide is fixedly installed on microwave generator.

[0013] Preferably, the regulation and control mechanism further includes fan, the fan is fixedly installed at the rear end of drying chamber, and the fan is fixedly connected with ventilation duct.

[0014] Compared with prior art, the utility model has the beneficial effects that:

[0015] 1. Improved drying quality and precise temperature control: Through an intelligent control system and temperature sensors, the equipment can precisely control the temperature inside the drying chamber. For example, at different stages of drying, the temperature can be precisely maintained within the optimal range, such as controlling the temperature at 40-50℃ in the early stage and appropriately increasing it to 50-60℃ in the later stage. This precise control avoids problems such as loss of nutrients or scorching of the white fungus due to excessively high temperatures, and excessively low temperatures leading to prolonged drying time, mold growth, and spoilage, thus ensuring the drying quality of the white fungus. 2. Uniform drying effect: The equipment's heating and ventilation systems work together to ensure uniform temperature and air distribution within the drying chamber. The heating method allows the white fungus to be heated simultaneously inside and out, and the rational design of the ventilation system (such as multi-hole air outlets) ensures even airflow among the white fungus. This helps the white fungus lose moisture evenly in all parts, avoiding over- or under-drying in certain areas, resulting in more consistent drying and more stable quality. 3. Improved drying efficiency and optimized heating method: Utilizing advanced heating elements (such as infrared heating tubes and microwave generators), the heating speed is faster compared to traditional heating methods. Infrared heating tubes directly heat the white fungus through radiation, while a microwave generator causes the water molecules inside the white fungus to vibrate rapidly, generating heat and significantly shortening the drying time. For example, traditional heating methods may take 8-10 hours to dry white fungus, while this intelligent equipment can reduce the drying time to 4-6 hours. A highly efficient ventilation system further enhances the drying process. The fans (centrifugal or axial fans) and ventilation ducts in the system effectively remove the moisture evaporated from the white fungus, maintaining a low humidity level in the drying chamber. Based on the principle that humidity affects drying speed, lower humidity accelerates the evaporation of moisture from the white fungus. Simultaneously, the ventilation system promotes the circulation of hot air, further improving drying efficiency.

[0016] 2、Energy saving and cost reduction, precise temperature control energy saving, intelligent control system can accurately adjust the heating power according to the actual demand of dried tremella. When tremella is close to dry completion, the system will automatically reduce the heating power to avoid energy waste caused by excessive heating. For example, through precise control, compared with traditional non-intelligent drying equipment, the device can save energy about 30% 40%. Good heat preservation performance reduces heat loss, and the heat preservation design of the drying chamber shell effectively reduces the heat loss to the outside. During the drying process, heat is concentrated in the drying chamber, reducing the frequent operation of the heating system to maintain temperature, thereby reducing energy consumption. This not only reduces energy costs, but also indirectly reduces equipment operating costs and maintenance costs. Intelligent and convenient, intelligent temperature control system, the intelligent control system of the equipment can automatically adjust the temperature according to the preset drying program. The operator only needs to set the drying temperature, time and other parameters on the control panel, and the equipment can automatically run. This intelligent operation method reduces the professional requirements for the operator, and can adapt to various tremella drying needs such as different varieties and different initial moisture of tremella by storing different drying programs. Easy to observe and operate, the observation window on the drying chamber door body is convenient for the operator to observe the drying state of tremella at any time. At the same time, the overall structure design of the equipment is reasonable, and the material placing structure is convenient for placing and taking out tremella. For example, the adjustable material rack can adapt to trays of different sizes, making it more convenient and fast to load and unload tremella, improving the convenience of operation. Prolong the service life and stability of the equipment, high-quality mechanical structure protection, the shell of the drying chamber is made of stainless steel, which has good corrosion resistance and can resist the corrosion of acidic substances that may be produced during the drying process of tremella. The reasonable design of the heating system, ventilation system and other mechanical structures and the selection of high-quality components make the equipment more stable during long-term operation. For example, the accuracy and reliability of the temperature sensor ensure the accuracy of temperature control, reducing damage to other parts of the equipment due to abnormal temperature, thereby prolonging the service life of the equipment. Stable operation environment maintenance, stable temperature, humidity environment and good ventilation conditions inside the equipment are not only conducive to the drying of tremella, but also conducive to the maintenance of the equipment. For example, the drying chamber will not be damaged due to high humidity of electrical components, nor will it accelerate the aging of components due to high temperature, ensuring stable performance of the equipment during long-term use and reducing the frequency of maintenance and replacement of components.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 - Figure 4 This utility model provides a technical solution: a smart temperature control device for drying tremella, including a main body 1 and a control mechanism 2. The control mechanism 2 is fixedly installed inside the main body 1. The main body 1 includes a control box 101, a shell 102, and a drying chamber 103. The shell 102 is fixedly installed on the outer surface of the control box 101, and the drying chamber 103 is fixedly installed inside the control box 101.

[0025] The control mechanism 2 includes a resistance wire 201, an infrared heating tube 202, and a microwave generator 203. Several resistance wires 201 are fixedly installed at the bottom of the drying chamber 103, infrared heating tubes 202 are fixedly installed on both sides of the drying chamber 103, and a microwave generator 203 is fixedly installed at the top of the drying chamber 103.

[0026] Preferably, the main body 1 further includes a base 104 and a door 105. The base 104 is fixedly installed at the bottom of the control box 101, and the door 105 is fixedly installed at the front end of the control box 101.

[0027] Preferably, the main body mechanism 1 further comprises an observation window 106 and a hinge 107, the observation window 106 is fixedly installed on the surface of the door body 105, and the hinge 107 is fixedly installed between the door body 105 and the control box 101.

[0028] Preferably, the main body mechanism 1 further comprises a ventilation duct 108 and an air outlet 109, the ventilation duct 108 is fixedly installed at the rear end of the control box 101, and the air outlet 109 is fixedly installed on the ventilation duct 108.

[0029] Preferably, the main body mechanism 1 further comprises a tray 110 and a net rack 111, the tray 110 is fixedly installed inside the drying chamber 103, and the net rack 111 is fixedly installed inside the drying chamber 103.

[0030] Preferably, the control mechanism 2 further comprises a control panel 204 and a waveguide 205, the control panel 204 is fixedly installed on one side of the front end of the control box 101, and the waveguide 205 is fixedly installed on the microwave generator 203.

[0031] Preferably, the control mechanism 2 further comprises a fan 206, the fan 206 is fixedly installed at the rear end of the drying chamber 103, and the fan 206 is fixedly connected with the ventilation duct 108.

[0032] Working principle: The structure of the drying chamber 103, the shell 102, the material and the characteristics, the shell 102 of the drying chamber 103 adopts stainless steel material, because stainless steel has good corrosion resistance, can resist the corrosion of acidic substances that may be produced in the drying process of silver ear. At the same time, the strength of stainless steel is high, can bear a certain pressure, provides stable structural support for the drying chamber 103. Its thickness is generally between 1 3mm, the specific thickness depends on the size and design pressure of the drying chamber 103. For example, for small silver ear drying equipment, the thickness of the shell 102 may be about 1mm; while the thickness of the shell 102 of large equipment may reach 3mm.

[0033] Heat preservation design, in order to reduce heat loss, the shell 102 will have a heat preservation layer. The heat preservation layer material can be rock wool, polyurethane foam, etc. Rock wool is a kind of inorganic fiber material, which has good heat preservation performance, and the thermal conductivity is usually between 0.03 0.04W / (m·K). The heat preservation performance of polyurethane foam is better, and the thermal conductivity can be as low as 0.02 0.03W / (m·K). The thickness of the heat preservation layer is generally between 50 100mm, by filling the heat preservation material between the shell 102 and the inner layer, the heat in the drying chamber 103 can be effectively preserved, and the energy consumption is reduced.

[0034] Door body 105 structure, sealing design, good sealing is required between the door body 105 of the drying chamber 103 and the shell 102 to prevent heat leakage and the entry of external air. A rubber sealing strip is installed on the edge of the door body 105, which has good elasticity and temperature resistance. When the door is closed, the strip will be compressed to form a tight seal. The material of the strip is generally silicone rubber, which has a wide operating temperature range and can maintain good elasticity between 50°C and 200°C, ensuring that the sealing of the door body 105 is not affected even if the temperature inside the drying chamber 103 is high during the drying process.

[0035] Observation window 106, in order to facilitate the observation of the drying of tremella in the drying chamber 103, an observation window 106 will be provided on the door body 105. The observation window 106 generally adopts a double-layer glass structure, and the two layers of glass are vacuum or filled with inert gas such as argon. This structure can effectively prevent heat conduction through the glass while ensuring good transparency, making it easy for operators to observe the color, shape and other drying conditions of tremella.

[0036] Heating system, heating element, type and characteristics, common heating elements include resistance wire 201, infrared heating tube 202 and microwave generator 203. Resistance wire 201 heating is through the passage of electric current through resistance wire 201 to generate heat, which has a relatively slow heating speed but low cost. Infrared heating tube 202 uses infrared radiation to heat, which can directly penetrate the air and be absorbed by tremella, resulting in high heating efficiency. Microwave generator 203 is a more advanced heating method that uses microwaves to make water molecules inside tremella vibrate, generating heat with fast and uniform heating speed.

[0037] Installation location and layout, resistance wire 201 is installed at the bottom of the drying chamber 103, which transmits heat to tremella through conduction and convection. For example, when installed at the bottom, heat rises, causing tremella to be heated. Infrared heating tube 202 is installed on the inner wall of the drying chamber 103 around the perimeter, which directly irradiates tremella through radiation, causing it to be heated. Microwave generator 203 needs to be arranged according to the characteristics of microwaves, usually installed at the top of the drying chamber 103, and the microwaves are evenly distributed into the drying chamber 103 through waveguide 205.

[0038] Ventilation system, fan 206, type and performance, fan 206 mainly includes centrifugal fan 206 and axial fan 206. Centrifugal fan 206 has high air pressure and can overcome the resistance in the ventilation system to effectively remove the moisture in the drying chamber 103. Its air volume is generally between 100 and 1000 m³ / h, and the specific air volume is selected according to the size of the drying chamber 103 and the drying speed requirements. The axial fan 206 has the characteristics of large air volume and low noise, which is suitable for use in cases where a large amount of ventilation is required, but its air pressure is relatively small.

[0039] Installation location and working mode, centrifugal fan 206 is installed at the rear end of drying chamber 103, connected with the outside through pipeline. When the fan 206 works, it will extract the humid air in the drying chamber 103, form negative pressure in the drying chamber 103, and the fresh air from the outside will enter the drying chamber 103 through the air inlet or pipeline, so as to realize the circulation of air. Axial fan 206 can be installed at one end of drying chamber 103, and the ventilation is realized by pushing the air flow.

[0040] Ventilation pipeline 108 and air outlet 109, pipeline material and size, ventilation pipeline 108 adopts galvanized iron sheet or plastic material. Galvanized iron sheet pipeline has high strength and good fireproof performance, which is suitable for long-term use; plastic pipeline has the characteristics of light weight and corrosion resistance. The size of the pipeline is determined according to the air volume and air speed of the fan 206, for example, for the fan 206 with air volume of 500m³ / h, the diameter of the ventilation pipeline 108 may be between 200 300mm, to ensure the smooth flow of air.

[0041] Material placing structure, tray 110 or net rack 111, material and carrying capacity, tray 110 or net rack 111 is used to place tremella, which can be made of stainless steel or plastic. The stainless steel tray 110 has the characteristics of high strength, high temperature resistance and easy cleaning, and can bear a certain weight of tremella. The plastic tray 110 is relatively light and relatively low in price. The carrying capacity of the tray 110 or the net rack 111 is determined according to the design requirements, which can generally bear 5 20kg of tremella to meet the drying needs of different scales.

[0042] Structural design and air permeability, the structural design of tray 110 or net rack 111 should consider the ventilation and drying effect of tremella. The mesh or porous design is adopted, which can ensure that the air can flow fully between the tremella, and improve the drying efficiency. For example, the mesh size of the mesh tray 110 is generally between 5 10mm, which can prevent the tremella from falling off and ensure good air permeability.

[0043] Material rack, number of layers and spacing, the number of layers and spacing should be determined according to the height of the drying chamber 103 and the size of the tray 110 or the net rack 111. The number of layers is generally between 3 8 layers, and the spacing is between 20 50cm. Reasonable number of layers and spacing can make full use of the space of the drying chamber 103, and ensure that each layer of tremella can get uniform drying conditions.

[0044] The dry chamber 103 is made of stainless steel, which is used to reduce heat loss due to its low thermal conductivity. The low thermal conductivity of stainless steel slows down the heat conduction within the material. Meanwhile, the thermal insulation material such as rock wool or polyurethane foam filled between the outer shell 102 and the inner layer can further prevent heat transfer. According to the heat conduction formula Q = kA\frac{dT}{dx}, the low thermal conductivity k of the thermal insulation material greatly reduces the heat transfer rate Q, effectively preserves the heat in the dry chamber 103, reduces heat loss to the external environment, and reduces energy consumption.

[0045] The silicone rubber sealant strip on the edge of the door body 105 relies on its elasticity to achieve sealing. When the door is closed, the sealant strip is compressed, causing elastic deformation. According to Hooke's Law F = kx, where F is the elastic force, k is the elastic coefficient, and x is the deformation, this elastic force makes the sealant strip tightly fit between the outer shell 102 and the door body 105, preventing air and heat exchange. For the observation window 106, the vacuum or inert gas layer such as argon between the double-layer glass uses the low thermal conductivity of the gas to insulate. Heat conduction has three main ways: conduction, convection, and radiation. The vacuum or inert gas layer reduces the two heat transfer methods of conduction and convection, ensuring that the observation of the dry state of the silver ear will not cause a large amount of heat loss due to the observation window 106.

[0046] The resistance wire 201 heats up when an electric current passes through it, according to Joule's Law Q = I^{2}Rt, where Q is the heat, I is the current, R is the resistance of the resistance wire 201, and t is the time. The resistance wire 201 generates heat. This heat raises the temperature of the surrounding air through heat conduction, and the hot air transfers heat to the silver ear through convection. For example, when the resistance wire 201 is installed at the bottom of the dry chamber 103, the air at the bottom is heated and rises, forming a natural convection, which heats the silver ear.

[0047] The infrared heating tube 202 heats up, and the infrared heating tube 202 emits infrared rays, which are a type of electromagnetic wave with a wavelength range typically between 0.76 1000 μm. When infrared rays hit the silver ear, the water molecules and organic molecules in the silver ear absorb the energy of the infrared rays, causing the molecules to vibrate and rotate more intensely. According to the law of conservation of energy, the energy absorbed by these molecules is converted into internal energy, thereby raising the temperature of the silver ear and achieving heating. This heating method directly acts on the silver ear through radiation, without the need for air as a medium, and has a high heating efficiency.

[0048] The microwave generator 203 generates microwaves with a frequency usually around 915MHz or 2450MHz. When the microwaves enter the drying chamber 103 and act on the tremella, the water molecules in the tremella are polar molecules. Under the action of the microwave electric field, the water molecules will rotate and vibrate quickly with the change of the microwave electric field. According to the kinetic theory of molecules, the movement of molecules intensifies to generate friction, which increases the internal energy of the water molecules and raises the temperature, thereby raising the overall temperature of the tremella. Moreover, microwaves can penetrate the tremella, allowing the inside and outside to be heated at the same time, and the heating uniformity is good.

[0049] The centrifugal fan 206 works when the motor drives the impeller to rotate. When the impeller rotates, the gas between the blades is thrown out of the impeller under the action of centrifugal force and enters the casing. The casing collects and guides the gas to the air outlet 109 for exhaust. According to the principle of fluid mechanics, a negative pressure is formed at the center of the impeller, and the outside air enters the impeller through the air inlet under the action of pressure difference, thereby realizing continuous delivery of air. Due to the large air pressure of the centrifugal fan 206, it can effectively overcome the resistance in the ventilation duct 108 and the drying chamber 103 to exhaust the humid air.

[0050] The axial fan 206 rotates the impeller under the drive of the motor, and the blades push the air to flow in the axial direction. Its working principle is similar to that of a propeller, which applies an axial thrust to the air through the rotating blades to make the air flow. The axial fan 206 is characterized by large air volume and low noise, and is suitable for use in situations where a large amount of ventilation is required, but its air pressure is relatively small. In the drying equipment, it mainly pushes the air in the drying chamber 103 to flow to realize the function of ventilation and air exchange.

[0051] The tray 110 or the grid 111 is made of stainless steel or plastic material to provide a platform for the tremella. Its mesh or porous structure is designed based on the principle of air convection. When the ventilation system is working, air can flow between the tremella through the mesh or pores of the tray 110 or the grid 111. According to the convection heat transfer formula Q = hA\Delta T, where Q is the convection heat transfer amount, h is the convection heat transfer coefficient, A is the heat transfer area, and \Delta T is the temperature difference, good ventilation can increase the convection heat transfer coefficient h, so that the moisture in the tremella can evaporate into the air more quickly, thereby improving the drying efficiency. At the same time, the air permeability of the tray 110 or the grid 111 can also ensure that all parts of the tremella can contact dry air, avoiding local dampness and achieving uniform drying.

[0052] Finally, it should be pointed out that the above content is only used to illustrate the technical solutions of the present application, and is not a limitation on the protection scope of the present application. Simple modifications or equivalent replacements of the technical solutions of the present application made by ordinary skilled in the art do not deviate from the essence and scope of the technical solutions of the present application.
