Abstract
Description
Technical Field
[0001] The invention relates to the technical field of agricultural planting, and in particular to a formula of moisture-absorbing and water-retaining seed pellets and an intelligent production line. Background Art
[0002] In agricultural production, getting "three seedlings" in one sowing, i.e., full seedlings, uniform seedlings and strong seedlings, is an important basis for the growth and high yield of crops. There are many problems with traditional dryland sowing methods, such as seeds are easily affected by environmental factors after sowing, resulting in low germination rate and uneven emergence. For wet crops such as rice, it is required to be mainly dry before the four-leaf stage, with alternating dry and wet conditions. However, in practice, it is often too dry, resulting in incomplete emergence of seedlings, or too flooded, resulting in weak seedlings or even drowning. In order to solve these problems, seed pelleting technology is an effective innovation. Especially in arid and semi-arid areas and saline-alkali areas, seed pelleting technology is of great significance for improving seed germination rate and seedling quality, and enhancing seedling resistance. Summary of the invention
[0003] The purpose of the present invention is to create a moisture absorbing and water retaining seed pellet formula and an intelligent production line. The machine can realize intelligent pellet processing of seeds and has good moisture absorbing and water retaining functions, thereby improving the germination rate of seeds and the quality of seedlings, enhancing the stress resistance of seedlings, reducing dependence on weather and irrigation, and improving drought resistance.
[0004] The technical problem to be solved by the present invention is achieved through the following technical solution: the production line comprises: 1. Intelligent control system The advanced sensor technology and automatic control technology are used to realize real-time monitoring and precise control of the seed pelleting process. By setting different parameters, such as temperature, humidity, pelleting multiple, etc., the operating state of the equipment is automatically adjusted to ensure the consistency of the pelleting effect. Specifically including: (1) Temperature sensor: monitors the ambient temperature in real time to ensure that the pelletizing process is carried out within an appropriate temperature range; (2) Humidity sensor: real-time monitoring of ambient humidity to ensure moisture supply during the pelletizing process; (3) Pelletization multiple sensor: real-time monitoring of the pelletization multiple to ensure consistent pellet size; (4) Automatic control unit: Automatically adjust the operating parameters of the equipment according to the data fed back by the sensor to ensure the consistency of the pelletizing effect.
[0005] 2. Moisture-absorbing and water-retaining materials Select materials with high water absorption and water retention, such as potassium polyacrylate, calcium peroxide, polyvinyl alcohol, etc., to form an isolation layer with the surface of the seeds, effectively absorb and retain water, and provide a suitable growth environment for the seeds. Specifically include: (1) Potassium polyacrylate: It has high water absorption and can absorb water vapor from the soil and air to provide sufficient moisture for seed germination; (2) Calcium peroxide: It has good water absorption and water retention properties and can effectively retain moisture in the pellets; (3) Polyvinyl alcohol: As an adhesive, it can evenly wrap the moisture-absorbing and water-retaining material on the surface of seeds to form an isolation layer.
[0006] 3. Pelletizing process The pellet coating process is divided into three stages: core formation stage, pellet enlargement stage and film forming and polishing stage. The specific steps are as follows: (1) Kernel formation stage: Through precise calculation and control, the seed surface is evenly coated with a layer of kernel material. The kernel material includes potassium polyacrylate, calcium peroxide and polyvinyl alcohol, which are mixed in a certain proportion; (2) Pellet enlargement stage: gradually add fillers and adhesives to gradually enlarge the pellets to the desired particle size. The fillers can be seedling substrates, rooting agents, etc., and the adhesive is polyvinyl alcohol solution; (3) Film-forming and polishing stage: The pellets are polished to make their surface smooth, further improving the quality and stability of the pellets.
[0007] 4. Drying Advanced drying technology is used to evenly dry the pelletized seeds to ensure consistent moisture content in the pellets and extend the storage period of the seeds. Specifically: (1) Vacuum drying: Use a vacuum dryer to evacuate the interior of the dryer body, and low-pressure steam enters the interlayer of the dryer body. The interlayer continuously transfers heat to the material. The first motor drives the first stirring paddle to rotate, and at the same time, the first motor drives the second rotating shaft to rotate around the interlayer shell. The second motor drives the second stirring paddle to rotate continuously. The first stirring paddle and the second stirring paddle continuously stir and tumble the material. The moisture of the material itself is sucked into the vacuum pump and then condensed and recovered through the condenser. During the drying process, the drying condition of the material inside the dryer body can be observed at any time through the observation window. After the drying is completed, the valve is opened to discharge the material, thereby realizing the drying process. Through the mutual cooperation of the first motor, the first stirring paddle, the second motor, and the second stirring paddle, the effect of thorough drying and uniform drying treatment is achieved, and the situation that the dried material still has some water vapor and absorbs moisture and returns to moisture is avoided.
[0008] (2) Hot air drying: Use a hot air dryer to control the drying temperature and time to ensure that the moisture content of the pellets is consistent. The hot air dryer allows the high-temperature hot air to fully contact the material, causing the moisture in the material to evaporate quickly to achieve the purpose of drying. The hot air dryer has the advantages of fast drying speed, high efficiency, and easy operation. It is suitable for drying various granular and powdery materials.
[0009] (3) Combined drying: Combining the advantages of vacuum drying and hot air drying, a combined drying method of vacuum drying followed by hot air drying is adopted to further improve the drying effect and efficiency. Vacuum drying is used to remove most of the moisture in the material, and then hot air drying is used to further reduce the moisture content of the material, ensuring that the moisture content of the pellets is consistent and extending the storage period of the seeds.
[0010] Due to the adoption of the above technical solution, the advantages and positive effects of the present invention are: 1. Improve germination rate: Compared with bare seeds, pelleting treatment significantly increased the germination speed and germination rate of rice seeds under flooding conditions. The germination rate was 15.56%-66.67% higher than that of bare seeds. 2. Promote seedling growth: Pelletization also promotes the growth of rice seedlings under flooding conditions, increasing the sprout length, root length, single sprout weight, and single root weight of rice seedlings by 2.8 times, 1.7 times, 3.1 times, and 2.6 times, respectively, compared with bare seeds; 3. Adapt to various sowing methods: suitable for mechanical precision hole direct seeding, aircraft direct seeding, manual broadcasting or row seeding and other sowing methods; 4. Reduce dependence on weather and irrigation: high-performance, safe, environmentally friendly and economical moisture-absorbing and water-retaining agents are mixed with seedling substrates, rooting agents and seed coating agents in a certain proportion and evenly wrapped on the surface of seeds to form pellets. By using its powerful moisture-absorbing and water-retaining effect, it reduces dependence on irrigation, saves water resources, prevents and reduces excessive exploitation of groundwater, and at the same time reduces agricultural production costs, solving the problem of waterless irrigation during sowing and germination in arid and semi-arid areas; 5. Extend the shelf life: Through precise drying process, the moisture content of the pellets is ensured to be consistent, thus extending the storage period of the seeds; 6. Improve sowing efficiency: The use of integrated seeder improves sowing efficiency and quality, shortens the time from unpacking the seed pellets to sowing into the soil, and realizes full mechanical integration and intelligence; 7. Innovative design of pelleting machine and vacuum packaging machine: improves the efficiency of pelleting and packaging, ensures the consistency of pellet quality and the tightness of packaging, and extends the shelf life of seed pellets; 8. Innovative design of vacuum packaging: It uses multi-layer composite materials and degradable materials, has good air tightness and waterproofness, can effectively prevent water loss and external pollution, and reduce pollution to the environment.
