In practice, the high moisture content of some straw materials complicates the processing process and increases energy consumption. Uneven moisture content in the straw also consumes additional energy during the crushing, drying, and pressing steps of straw fuel production, increasing energy consumption, reducing production capacity, and impacting production efficiency.

[0021] 1. Basic structure and function
[0022] like Figures 1 to 3 As shown, the moisture-based biomass multi-path utilization system of the present invention mainly includes a biomass pellet production line and a fertilizer feed production line, and also includes a portable moisture detector 1, a control host 12 and a small drying kiln 3.
[0023] A portable moisture detector performs preliminary sorting, and raw materials with a moisture content significantly higher than 60% that are not suitable for straw fuel production are sorted and transported to a straw winnowing machine by a conveyor belt; the remaining raw materials are transported to a moisture detection unit by another conveyor belt system; a small drying kiln dries materials with a moisture content between 50% and 60% to below 50%. It can adjust the moisture content of the output material by adjusting the temperature and drying time, and after drying, it is transported to a coarse crusher by a conveyor belt device.
[0024] The biomass pellet production line mainly consists of a moisture detection unit 2, a coarse crusher 4, a fine crusher 5, a biomass combustion furnace drying kiln 6 and a biomass pellet machine 7 which are sequentially connected by a conveyor belt.
[0025] The biomass burning furnace drying kiln uses part of the fuel produced by the biomass pellet machine as its fuel, which can achieve good combustion effect. Moreover, the fuel is produced in our factory, which is economical, affordable and environmentally friendly.
[0026] The fertilizer feed production line includes a feed production branch line and a fertilizer production branch line. The feed production branch line is mainly composed of a conveyor belt sequentially connected to a straw air separator 8, a biomass fermentation tank 13, a feed mixer 14 and a feed pellet machine 15. The fertilizer production branch line is mainly composed of a conveyor belt sequentially connected to a straw air separator, a fertilizer strain spiral feeder 11 and a fertilizer pellet machine 16.
[0027] The straw winnowing machine uses straw raw material, sorted by a portable moisture detector and moisture detection unit, for feed and fertilizer production. The winnowing machine can adjust the moisture sorting conditions based on actual feed and fertilizer production needs, feeding the moisture detection unit. It can also control the amount of material delivered to the silage additive feeder 9, compressed feed additive feeder 10, and fertilizer culture spiral feeder based on the material's moisture content, freshness, and the desired quantity of finished product. For example, a 3cm size threshold can be selected as the screening threshold for fertilizer and feed production: materials above 3cm are used for fertilizer production, while those below 3cm are used for feed production.
[0028] The fertilizer strain spiral feeder processes the material into biomass fertilizer, that is, adding a quick-rotting agent to the material, adjusting the moisture content to about 65%, fully stirring it through the spiral feeder, and using various strains and enzymes to quickly decompose it.
[0029] The moisture detection unit and the straw winnowing machine are connected to each other by a conveyor belt, and the coarse crusher and the biomass fermentation tank are connected by a conveyor belt; the control host is connected to and controls the coarse crusher and the biomass fermentation tank, and the moisture detection unit is connected to the coarse crusher through a conveyor belt and a small drying kiln.
[0030] The moisture detection unit primarily consists of a moisture detection device 206 and its housing. The moisture detection device is housed within the housing, with a conveyor belt 204 extending through the housing. A sensor 207 within the moisture detection device is located above the conveyor belt. The housing is equipped with an inspection door 203, a control panel 201, a status display panel 202, and a main control computer 205. The main control computer is connected to and controls the moisture detection device, control panel, and status display panel.
[0031] The moisture detection unit accurately measures the moisture content of materials passing through a portable moisture detector and further sorts them. The material to be tested is transported by a conveyor belt to the bottom of the moisture detection unit, where a sensor rapidly detects its moisture content. Real-time data is fed back to the main control computer and displayed on a status display panel. The main control computer then controls the conveyor belt to transport the material to the target device based on preset moisture thresholds. The control panel can adjust the moisture thresholds and multiple sorting intervals set by the main control computer to meet the needs of actual production processes. For example, materials with a moisture content above 60% are sent to a straw winnowing machine, materials with a moisture content between 50% and 60% are sent to a small drying kiln, and materials with a moisture content below 50% are sent to a coarse crusher.

[0046] 2. Working Principle and Process
[0047] The portable moisture detector is used to quickly sort out straw with a moisture content significantly higher than 60%, and transport it to the straw air separator via a conveyor belt, while the remaining materials are transported to the moisture detection unit. After determining the moisture content, the moisture detection unit controls the conveyor belt system according to the preset moisture threshold to transport materials with different moisture contents to different devices. Generally, raw materials with a moisture content higher than 60% are transported to the straw air separator, raw materials with a moisture content between 50% and 60% are transported to a small drying kiln, and raw materials with a moisture content lower than 50% are transported to a coarse crusher. The small drying kiln dries the material to a moisture content below 50% and then transports it to the coarse crusher. The coarse crusher performs the initial crushing of the straw material, which is driven by a conveyor belt and then sequentially processed into a fine crusher, a biomass combustion furnace drying kiln, and a biomass pellet machine to finally make straw fuel. The straw air separator uses straw raw materials that have been sorted by a portable moisture detector and a moisture detection unit for feed and fertilizer production. Specifically, the materials that have been preliminarily processed by the straw air separator are conveyed by a conveyor belt and further processed by silage additive addition operations, compressed feed additive addition operations, or fertilizer culture spiral feeders; the materials after silage and compressed feed with additives are conveyed to the biomass fermentation tank, and the coarse crusher adds part of the crushed straw with a lower moisture content into the biomass fermentation tank under the control of the main machine, and mixes it with the material with a higher moisture content in the fermentation tank, thereby controlling its overall moisture content at around 60%. After fermentation in the biomass fermentation tank, the materials are sequentially conveyed to the feed mixer and feed pellet machine to produce finished feed products; the materials entering the fertilizer culture spiral feeder are conveyed to the biomass fermentation tank for processing and then to the fertilizer pellet machine to produce finished fertilizer products.
[0048] in,
[0049] The addition of silage additives is a pre-treatment process for processing materials into silage. Fermentation additives, rice bran, corn flour, wheat bran, etc. can be added to the materials, fully stirred, and the moisture content is adjusted to 65-75%. The materials are then fermented in a biomass fermentation tank. After fermentation, they are stirred and mixed in a feed mixer and then directly pelletized.
[0050] The addition of compressed feed additives is the pre-treatment of materials into compressed feed. After adding the compressed feed additives, the materials are directly fed into the biomass fermentation tank for quick and simple composting. Then, vitamins, trace elements, non-protein nitrogen and other additives are added to them. After being stirred and mixed by the feed mixer, they are sent to the feed pellet machine for feed pelleting.
[0051] In summary, the system of the present invention significantly optimizes the production of traditional straw fuel by designing a multi-stage moisture detection and sorting system and a multi-path utilization system, reduces production energy consumption, reduces labor, realizes automated production, and significantly improves production capacity.
