Description

Technical Field

[0001] The invention relates to the technical field of agricultural product fermentation devices, and in particular to a fermentation system based on green rice sprouts. Background Art

[0002] In today's society, with the continuous development of agricultural production, the leftover vegetable seedlings, as a by-product of the growth of crops, have become a thorny environmental problem. Leftover vegetable seedlings are domestic waste. They are not edible for humans, and livestock are unwilling to eat them due to their poor taste and difficulty in absorbing nutrients. It is even difficult to use them as biogas materials. In urban environments, a large number of leftover vegetable seedlings are randomly piled up on the sides of the road or in ditches, which not only seriously affects the appearance of the city, but also breeds a large number of bacteria due to long-term stacking, posing a threat to the health of surrounding residents. Moreover, these deposits will occupy road space, hinder the normal passage of pedestrians and passing vehicles, create traffic hazards, and bring many inconveniences to the orderly operation of the city.

[0003] At the same time, from the perspective of sustainable agricultural development, soil nutrient balance is crucial. In the process of crop pruning, leaf removal, and crop rotation, a large amount of waste from green seedlings will be generated. These wastes contain many nutrients required for plant growth. If they are directly discarded, it will cause a huge waste of soil nutrients, which will lead to a decline in soil fertility in the long run, affecting the yield and quality of subsequent crops.

[0004] In view of this situation, an innovative solution is urgently needed to effectively deal with the problem of leftover vegetables and green seedlings. This green seedling leftover vegetable fermentation system came into being. It is a key response strategy based on the nutrient balance of the land. Its core principle is to first use a specific crushing process to make the leftover vegetable and green seedling waste generated during the growth of crops into a state suitable for fermentation. Then, the fermentation process is used to convert the waste into a nutrient solution rich in nutrients, which is finally accurately re-irrigated to the roots of the plants through drip irrigation. On the one hand, it avoids environmental pollution caused by the arbitrary discarding of leftover vegetables and green seedlings. On the other hand, it realizes the efficient recycling of land nutrients, providing strong support for the sustainable development of agricultural ecology. Summary of the invention

[0020] Combined with Figure 1 To Attachment Figure 2 As shown, it relates to a fermentation system based on green vine tail vegetable, which is characterized by: comprising a crushing system, a fermentation system and a solar energy supply system, the crushing system is used for crushing and filtering the green vine tail vegetable, the fermentation system is used for fermenting the crushed green vine tail vegetable, and the solar energy supply system is used for supplying heat to the fermentation system; the crushing system adopts a crusher 1 integrated with spiral feeding extrusion, reamer crushing and sieve filtering; the solar energy supply system includes an integrated solar energy collector 2, a high-level oil tank 8, an energy storage facility 9, an energy storage medium, a heat exchanger 10, a water storage tank 7 and a circulating pump 11; the fermentation system includes a plurality of vertical tank bodies 3, the upper part of the vertical tank body 3 is provided with a feed port 4, a sight glass, a manhole, and a cleaning head, the lower part is provided with a slag outlet 5 and a sewage outlet 6, the outside of the vertical tank body 3 is provided with a hot water jacket 12 and a thermal insulation layer, and the hot water jacket 12 is cyclically connected with the solar energy supply system through a heating pipe 13 and a water outlet pipe 14.

[0021] The integrated crusher 1 is equipped with a variety of reamers and screens, and the motor has stepless speed regulation, and the crushing speed, reamer type and screen hole diameter can be selected according to the material characteristics.

[0022] The solar thermal collector 2 uses a trough solar collector with a tracking system to collect heat; the energy storage facility 9 uses a water-selected sintered gravel heat accumulator, which is composed of sintered gravel, porous ceramic balls, and stainless steel wire mesh; the energy storage medium is heat transfer oil, and the heat storage temperature is 180°C, which automatically provides heat for the fermentation system to ensure a fermentation temperature of 40°C±2°C in winter.

[0023] The trough solar collector, water-selected sintered gravel heat storage device, heat exchanger 10 and high-level oil tank 8 form a storage medium circulation loop through filter 15 and circulation pump 2 16. The water storage tank 7, heat exchanger 10, heating pipe 13, hot water jacket 12 and water outlet pipe 14 form a heating water circulation loop through circulation pump 11.

[0024] The sewage outlets 6 at the bottom of the multiple vertical tanks 3 are combined through the sewage pipe 17 and then discharged through the centrifugal pump 18. The integrated crusher 1 is loaded by the scraper conveyor 19, and the crushed materials are transported to the material trolley 21 by the scraper conveyor 20. The vertical tank 3 is loaded by the elevator 22 and the material trolley 21.

[0025] The present invention relates to a fermentation system based on green rice sprouts. The working process is as follows: 1. Raw material pretreatment: First, collect the discarded green leafy vegetables and put them into the crushing and filtering integrated machine 1. According to the characteristics of the material, the integrated machine uses spiral feeding extrusion, reamer crushing and sieve filtration to work together, the motor has stepless speed regulation, and the combination of precisely matched reamer and sieve can efficiently crush the green leafy vegetables and filter impurities, preparing the raw materials for subsequent fermentation.

[0026] 2. Transfer of fermentation materials: The green leaf mustard residue obtained by crushing and filtering is accurately and stably transported to the vertical tank body 3 by manual handling or with the help of a hoist to start the fermentation process.

[0027] 3. Guarantee of heat supply: In view of the strict temperature requirements of fermentation, the vertical tank body 3 is equipped with a hot water jacket 12. As the core heating component, the trough solar collector 2 is responsible for collecting and converting solar energy into thermal energy. The water-selected sintered gravel heat accumulator uses sintered gravel and porous ceramic balls to store heat. After the energy storage medium absorbs heat, it exchanges heat with water in the heat exchanger. At the same time, the system's supporting water storage tank 7 provides circulating water. When the water flows through the heat exchanger 10, it absorbs heat. The heated hot water is transported along the pipeline to the hot water jacket 12 of each vertical tank body 3, creating a suitable warm environment for fermentation; after completing the heat transfer, the cooling water flows back to the water storage tank 7, and then flows to the heat exchanger 10 to absorb heat again. This reciprocating process builds a stable and efficient circulating heating and cooling water system to ensure constant temperature throughout the fermentation process.

[0028] 4. Fermentation process control: During the fermentation process, each vertical tank 3 has its own complete process port configuration, including discharge port, breathing port, sampling port, cleaning port, manhole, sight glass, pH meter interface, temperature measurement interface and slag discharge door, as well as built-in filter and stirring device, to fully meet the diverse fermentation process requirements such as real-time monitoring, precise control, material in and out, equipment maintenance, etc. With the help of these interfaces and devices, operators can keep track of the fermentation dynamics at any time, such as monitoring fermentation parameters through the pH meter interface and temperature measurement interface, and adjusting the fermentation conditions in a timely manner based on data feedback.

[0029] 5. Wastewater discharge and final treatment: As fermentation progresses, the waste generated in each vertical tank body 3 is collected to the wastewater outlet 6 under the action of gravity and discharged uniformly through the wastewater pipe 17 to maintain a clean fermentation environment. After the previous multiple vertical tank bodies 3 complete the staged fermentation tasks, the output of the liquid material flows to the last vertical tank body 3, where the key last step of the fermentation process is completed. When all indicators of the material liquid meet the standards and the fermentation is successfully completed, the qualified material liquid is discharged from the tank body and enters the next production link, delivering high-quality organic fermentation products for subsequent agricultural applications or other processing processes.
