[0002] After harvesting, morels need to be processed in time. With the maturity of artificial cultivation technology and the prominent benefits, farmers' enthusiasm for morel cultivation has gradually increased, and small-scale growers are still the main ones. At present, the popularity of grading and drying energy-saving equipment suitable for small-scale morel production areas is low. There are three main grading specifications for morels: Level 1: cap 8-12cm, stipe ≤4cm, Level 2: cap 5-8cm, stipe ≤3cm, Level 3: cap 3-5cm, stipe ≤2cm. It is necessary to do a good job of grading immediately after harvesting morels.

[0003] In the traditional grading method, workers need to manually select morels of different sizes, which is not only time-consuming and laborious, but also difficult to ensure the grading accuracy. In addition, due to the subjectivity of manual operation, there are often large differences in grading results, which affects the efficiency of subsequent drying and packaging.

[0004] In terms of drying, traditional drying methods such as natural drying and hot air drying have problems such as uneven drying, high energy consumption, and long time.

DETAILED DESCRIPTION

[0023] As a rare edible mushroom, Morchella is favored by consumers for its unique taste and rich nutritional value. However, the origin of Morchella is widely distributed and is greatly affected by seasonal and climatic conditions, which makes it difficult to preserve fresh Morchella for a long time after harvest. Therefore, the development of efficient Morchella origin grading and drying equipment is of great significance to improve the shelf life of Morchella, maintain its original quality and meet market demand.

[0024] Morchella spp. is a rare wild edible mushroom, named for its uneven cap that resembles a tripe. Rich in protein, minerals, vitamins and other nutrients, it has a unique aroma and taste, and is known as the "king of mushrooms." However, Morchella requires a high growth environment and has a short harvest period, so the preservation and transportation of fresh Morchella has become one of the key factors restricting the development of its industry.

[0025] Drying is an effective means to extend the shelf life of morels and maintain their original quality. Drying can reduce the moisture content of morels, inhibit the growth and reproduction of microorganisms, and thus extend their shelf life. At the same time, the drying process can also make the aroma of morels more intense and the taste more unique. Therefore, the development of efficient origin-grading drying equipment for morels is of great significance to the development of the morel industry.

[0026] At present, the drying technology of morels mainly includes natural drying, hot air drying, vacuum drying and freeze drying, etc. These drying technologies have their own advantages and disadvantages and are suitable for different production conditions and needs.

[0027] Natural drying

[0028] Natural drying is the most traditional method of drying morels. It uses natural wind and sunlight to dry morels. This method is simple and easy to implement, with low cost, but the drying time is long and is greatly affected by weather conditions. At the same time, during the natural drying process, morels are easily contaminated by dust, insects, etc., which affects the product quality.

[0029] Hot air drying

[0030] Hot air drying heats the air and blows it into the drying chamber to evaporate the moisture on the surface of the morels. This method dries quickly and can control the drying process by adjusting the temperature and humidity. However, during the hot air drying process, the morels are easily damaged by high temperatures, resulting in a decrease in quality. In addition, hot air drying also consumes a lot of energy, which increases production costs.

[0031] Vacuum drying

[0032] Vacuum drying is the process of drying morels under vacuum conditions. This method can significantly reduce the drying temperature and avoid high temperature damage to the quality of morels. At the same time, vacuum drying can also speed up the evaporation of water and shorten the drying time. However, vacuum drying equipment is complex, costly, and requires high operating technology. In addition, morels are prone to deformation and cracking during vacuum drying, affecting product quality.

[0033] Freeze drying

[0034] Freeze drying is to freeze the morels below freezing point and then dry them by sublimating the ice crystals under vacuum conditions. This method can maximize the preservation of the original quality and flavor of the morels. However, freeze drying equipment is complex, energy-intensive, expensive, and takes a long time to dry. Therefore, freeze drying is mainly suitable for high-end markets and special needs.

[0035] In view of the shortcomings of Morchella drying technology, domestic and foreign scholars and enterprises have carried out research and development of Morchella origin graded drying equipment. These equipment have made significant progress in structural design, function realization and intelligent control.

[0036] Structural design

[0037] The existing morel origin grading and drying equipment mainly considers the following aspects in structural design:

[0038] (1) Modular design: In order to facilitate maintenance and upgrading, many morel production grading and drying equipment adopts modular design. This design allows each part of the equipment to be disassembled and replaced independently, reducing maintenance costs and time. At the same time, modular design also allows the equipment to be flexibly configured and adjusted according to different production needs.

[0039] (2) Grading system: In order to improve drying efficiency and product quality, many grading and drying equipment in the production areas of morels are equipped with a grading system. This system can grade morels according to their size, shape, quality and other characteristics, ensuring that morels of different qualities can be properly dried. The grading system usually includes a vibrating screening machine, a grading conveyor belt and a grading drying chamber.

[0040] (3) Hot air circulation system: In order to improve drying efficiency and uniformity, many grading and drying equipment for morels are equipped with hot air circulation systems. The system heats the air and blows it into the drying room, evaporating the moisture on the surface of the morels to achieve the purpose of drying. At the same time, the hot air circulation system can also discharge the hot and humid air in the drying room and recycle it, reducing energy consumption and emissions.

[0041] (4) Temperature control system: In order to ensure that the morels are not damaged by high temperatures during the drying process, many grading and drying equipment for morels are equipped with temperature control systems. The system can accurately control the drying process according to the set temperature and humidity parameters to ensure that the morels are dried under suitable temperature and humidity conditions. The temperature control system usually includes temperature sensors, humidity sensors, and controllers.

[0042] Functionality

[0043] The existing morel origin grading and drying equipment mainly considers the following aspects in terms of function realization:

[0044] (1) Automated operation: In order to improve production efficiency and reduce labor costs, many morel production grading and drying equipment have achieved automated operation. These equipment automatically control the drying process through preset programs and parameters, reducing human intervention and errors. At the same time, automated operation can also achieve continuous operation and remote monitoring of equipment, improving production efficiency and safety.

[0045] (2) Intelligent control: In order to further improve production efficiency and product quality, many morel production grading and drying equipment have adopted intelligent control technologies. These technologies include Internet of Things technology, big data analysis technology, and artificial intelligence algorithms, which can monitor and optimize the drying process in real time. For example, through the Internet of Things technology, the operating status and data of the equipment can be transmitted to the cloud platform in real time for analysis and processing; through big data analysis technology, historical data can be mined and analyzed to provide a scientific basis for optimizing the drying process; through artificial intelligence algorithms, the drying process can be predicted and controlled to improve production efficiency and product quality.

[0046] (3) Energy saving and environmental protection: In order to respond to the national call for energy conservation and emission reduction and reduce production costs, many morel production grading and drying equipment focus on the application of energy-saving and environmental protection technologies in the design and manufacturing process. For example, the use of high-efficiency and energy-saving heating elements and fans can reduce energy consumption; the use of waste heat recovery technology can recycle waste heat in the drying process; and the use of environmentally friendly materials can reduce pollution to the environment.

[0047] Practical Application

[0048] Existing grading and drying equipment for morels has been widely used in many regions. These equipment have achieved remarkable results in improving the drying efficiency of morels, maintaining product quality, and reducing production costs. For example, after adopting grading drying equipment in some regions, the drying time of morels has been shortened by more than 30%, and the product quality has been significantly improved; after adopting automation and intelligent control technology in some enterprises, the production efficiency has increased by more than 50%, and the labor cost has been reduced by more than 20%.

[0049] Although the existing Morchella origin grading and drying equipment has made certain progress and achievements, it still faces some technical challenges and problems. At the same time, with the continuous advancement of science and technology and the changes in market demand, the future development trend of Morchella origin grading and drying equipment will also present some new characteristics and directions.

[0050] Technical Challenges

[0051] (1) Drying uniformity: Due to the large differences in shape and size of morels, uneven drying is prone to occur during the drying process. This not only affects product quality, but also increases energy consumption and emissions. Therefore, how to improve drying uniformity is one of the technical problems that needs to be solved urgently.

[0052] (2) Insufficient intelligence level: Although the existing grading and drying equipment for morels production has achieved a certain degree of automation and intelligent control, the overall intelligence level is still relatively low. This limits the further improvement of the equipment in terms of production efficiency and product quality. Therefore, how to improve the intelligence level of the equipment is one of the technical directions that need to be focused on.

[0053] (3) Energy-saving and environmental protection technologies need to be improved: As the country's requirements for energy conservation and emission reduction become increasingly stringent, the energy-saving and environmental protection technologies of Morchella production grading and drying equipment also need to be continuously improved. For example, it is necessary to develop more efficient and energy-saving heating elements and fans; it is necessary to adopt more advanced waste heat recovery technologies; it is necessary to promote the use of environmentally friendly materials, etc. The improvement of these technologies will help reduce production costs and reduce pollution to the environment.

[0054] Future development trends

[0055] (1) High-efficiency energy-saving technology: With the increasing national requirements for energy conservation and emission reduction and the rise in energy prices, high-efficiency energy-saving technology will become one of the important development directions of grading and drying equipment for morels. For example, more advanced heating methods and control technologies can be used to improve energy efficiency; waste heat recovery and recycling technologies can be used to reduce energy consumption; new insulation materials and structures can be used to reduce heat loss, etc. The application of these technologies will help reduce production costs and improve economic benefits.

[0056] (2) Intelligent control technology: With the continuous development of technologies such as the Internet of Things, big data and artificial intelligence, intelligent control technology will become one of the important development directions of grading and drying equipment for morels. For example, the Internet of Things technology can be used to achieve remote monitoring and fault warning of equipment; the drying process can be optimized and adjusted through big data analysis technology; the drying process can be predicted and controlled through artificial intelligence algorithms, etc. The application of these technologies will help improve production efficiency, maintain product quality and reduce labor costs.

[0057] (3) Multifunctional integration technology: In order to meet the diverse needs of different users and improve the utilization rate of equipment, multifunctional integration technology will become one of the important development directions of grading and drying equipment for morel production areas. For example, functions such as grading, hot air circulation, and temperature control system can be integrated into one equipment; functions such as drying, packaging, and storage can be integrated into one production line. The application of these technologies will help improve the flexibility and adaptability of equipment and meet the diverse needs of different users.

[0058] (4) Environmentally friendly materials and technologies: With the continuous improvement of environmental awareness and the continuous improvement of laws and regulations, environmentally friendly materials and technologies will become one of the important development directions of morel production grading and drying equipment. For example, more environmentally friendly materials can be used to manufacture equipment; more advanced wastewater treatment technology and waste gas treatment technology can be used to reduce environmental pollution; renewable energy can be used to replace traditional energy, etc. The application of these technologies will help reduce environmental pollution and improve the sustainability of equipment.

[0059] In summary, the research and development and application of the origin-grading drying equipment for morels are of great significance for improving the shelf life of morels, maintaining their original quality and meeting market demand. The existing origin-grading drying equipment for morels has made significant progress in structural design, function realization and intelligent control, but it still faces some technical challenges and problems. In the future, with the continuous advancement of science and technology and changes in market demand, the origin-grading drying equipment for morels will develop in the direction of high efficiency and energy saving, intelligent control, multifunctional integration and environmentally friendly materials and technologies. This will help to further improve the drying efficiency of morels, maintain product quality and reduce production costs, and promote the sustainable development of the morel industry.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0061] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0063] After harvesting, the morels are first sent to a screening mechanism. The screening mechanism sizes the morels through multiple screening parts inside it. The graded morels are then sent to a drying box 2 connected to the screening part, and the graded drying part performs targeted drying treatment. The heating part provides the required heat to ensure the smooth progress of the drying process. The present invention can automatically complete the grading and drying process, reduce manual intervention, and improve production efficiency and product quality. At the same time, the equipment should also have the advantages of simple structure, easy operation, and low energy consumption to meet the needs of the modern food industry.

The top surface of the first connecting seat 3 is fixedly connected to a first motor 4, and the output shaft of the first motor 4 is fixedly connected to a cam 5, which abuts against the bottom surface of the screening frame 1.

[0065] The first motor 4 is in contact with the bottom surface of the screening frame 1 through the cam 5, driving the screening frame 1 to reciprocate. This movement helps to evenly distribute and grade the morels on the screening part. The design of the drive unit makes the screening process more automated and efficient, reducing the tediousness of manual operation.

[0066] A further optimization scheme is that the end of the screening frame 1 close to the drying box 2 is symmetrically rotatably connected with the fixed leg 6, the side wall of the screening frame 1 away from the fixed leg 6 is symmetrically provided with a first slide groove 7, the first connecting shaft 8 is slidably connected in the first slide groove 7, one end of the first connecting shaft 8 located in the screening frame 1 is fixedly connected to a limiting plate 9, the two sides of the screening frame 1 are symmetrically slidably connected with supporting legs 10, the top of the supporting leg 10 is provided with a second slide groove 11, and the first connecting shaft 8 is slidably connected in the second slide groove 11.

[0067] The screening frame 1 is stably supported by the fixed legs 6 and the support legs 10. During the screening process, the screening frame 1 reciprocates under the drive of the cam 5, and the support legs 10 are slidably connected to the first connecting shaft 8 through the second slide groove 11, thereby ensuring the stability and movement flexibility of the screening frame 1.

The second screening element includes a second screening net 15 arranged on the screening frame 1. The bottom of the second screening net 15 is fixedly connected to a second collecting cover 16. The bottom of the second collecting cover 16 is connected to a second connecting pipe 17, which is connected to the drying box 2. The third screening element includes a third screening net 18 arranged on the screening frame 1. The bottom of the third screening net 18 is fixedly connected to a third collecting cover 19. The bottom of the third collecting cover 19 is connected to a third connecting pipe 20, which is connected to the drying box 2.

[0069] According to a further optimized solution, one end of the third connecting pipe 20 communicating with the drying box 2 is located above the second connecting pipe 17 , and one end of the second connecting pipe 17 communicating with the drying box 2 is located above the first connecting pipe 14 .

[0070] The morels are screened step by step by the first screening net 12, the second screening net 15 and the third screening net 18 and are classified into different size grades. A collecting cover and a connecting pipe are provided at the bottom of each screening net to send the classified morels into the drying box 2. The multi-stage screening design ensures the accurate classification of the morels and provides a basis for the subsequent drying process.

[0071] A further optimized solution is that the graded drying section includes a driving box 21 arranged on the bottom surface of the drying box 2, a second motor 22 is fixedly connected to the driving box 21, an output shaft of the second motor 22 is fixedly connected to a second connecting shaft 23, the second connecting shaft 23 passes through the driving box 21 and is rotatably connected to the top surface of the drying box 2, a first screening disc 24, a second screening disc 25 and a third screening disc 26 are fixedly connected to the second connecting shaft 23 from bottom to top, the first screening disc 24 is located below the first connecting pipe 14, the second screening disc 25 is located between the first connecting pipe 14 and the second connecting pipe 17, and the third screening disc 26 is located between the second connecting pipe 17 and the third connecting pipe 20.

[0073] To further optimize the solution, weight sensors are provided at the bottom of the first screening plate 24, the second screening plate 25 and the third screening plate 26. The weight sensors monitor the weight of the morels on the screening plates in real time to ensure the uniformity of the drying process. When the dehydration rate reaches a preset threshold (such as the moisture content of the first-grade product ≤ 12%), the system automatically stops heating the corresponding screening plate to avoid over-drying.

[0074] In a further optimized solution, the heating unit includes a heat pump main unit 27 disposed in the drying box 2, and the heat pump main unit 27 is connected to a hot air circulation fan 28.

The design of the heating unit ensures that the heat supply during the drying process is sufficient and uniform, thereby improving the drying efficiency.

[0075] To further optimize the solution, a heat exchange mechanism is provided in the drying box 2, and the heat exchange mechanism includes a temperature and humidity sensor 29 arranged in the drying box 2.

The design of the heat exchange mechanism helps to maintain the temperature and humidity stability in the drying box 2 and ensure the smooth progress of the drying process. At the same time, the use of the exhaust fan 31 also helps to extend the service life of the drying box 2.
