【引言】
在农业绿色发展大背景下，种养循环已经成为规模化蛋鸡基地的硬性建设指标。既要守住养殖端的环保底线，又要实现粪污变粪肥、反哺种植，很多大型基地卡在粪污处置这一环：传统堆肥周期长、品质不稳定，粪肥还田的闭环始终跑不通。
今天通过真实落地项目纪实，看大型蛋鸡基地如何借助卧式闪蒸成套烘干设备，真正打通“蛋鸡养殖粪污无害化处理干粪还田种植” 完整循环链路，同时完成环保考核与种养循环项目双重验收，形成可复制、可落地的样板模式。
Against the backdrop of green agricultural development, the planting‑breeding circular system has become a mandatory construction indicator for large‑scale layer chicken bases. Farms must uphold environmental protection bottom lines for breeding operations while turning manure into fertiliser to nourish crop cultivation. Many large bases hit a bottleneck in manure disposal: traditional composting features long cycles and unstable quality, preventing a closed loop of manure fertiliser application to farmland.
Today, through a real‑world project case study, we examine how a large layer base leverages a complete horizontal flash drying system to establish a full circular chain: layer breeding → harmless manure treatment → dried manure return to farmland. The project passed both environmental assessments and planting‑breeding circular programme acceptance, forming a replicable, practical benchmark model.
一、项目背景：大型蛋鸡基地的现实困境，种养循环建设迫在眉睫
本项目为当地重点规模化蛋鸡养殖基地，园区自有标准化蛋鸡舍，同时配套连片果蔬、粮食种植基地，属于地方重点推进的种养循环示范创建主体。
基地每日持续产出大量鲜鸡粪，一方面要面对常态化环保巡查，严禁粪污随意堆放、外溢；另一方面项目申报种养循环示范基地，政策明确要求实现粪污就地资源化、就近还田利用，不能简单依靠外运处置。
现实矛盾摆在眼前：养殖端持续产出粪污，种植端需要优质有机肥原料，但中间粪污无害化处理环节跟不上，种养闭环难以真正落地。
I. Project Background: Practical Dilemmas of Large‑scale Layer Bases, Urgent Demand for Planting‑breeding Circular Construction
This project concerns a key local large‑scale layer breeding base. The park contains standardised layer houses and supporting contiguous fruit, vegetable and grain planting plots, serving as a demonstration entity prioritised by local authorities for building a planting‑breeding circular economy.
The base continuously generates massive volumes of fresh chicken manure daily. On one hand, routine environmental inspections prohibit random stockpiling or leakage of manure. On the other hand, as an applicant for the planting‑breeding circular demonstration base designation, it must meet policy requirements for on‑site resource utilisation and nearby farmland application of manure, rather than merely relying on off‑site transport for disposal.
A practical conflict emerged: breeding produces continuous manure output while crop cultivation demands high‑quality organic fertiliser raw materials. However, inadequate intermediate harmless manure treatment prevented realisation of the closed planting‑breeding loop.
二、原有处置模式痛点，循环模式难以真正跑通
在改造之前，基地尝试过外运 + 露天堆肥相结合的传统模式，但暴露出诸多短板，无法满足示范项目建设要求：
1.粪污外运成本居高不下：每日粪污外包清运，运费逐年上涨，遇到雨季处置点位饱和，还会出现无人接收的情况，粪污消纳完全受制于外部渠道；
2.堆肥周期漫长，周转场地压力大：自然堆肥腐熟周期动辄数月，需要大面积堆肥场地，基地土地资源紧张，雨季堆肥还会出现渗流、恶臭扰民风险；
3.粪肥成品品质不稳定：受天气影响大，腐熟程度参差不齐，部分物料虫卵、病菌未彻底杀灭，直接还田容易带来病虫害隐患，肥效波动大；
4.无法满足项目验收标准：单纯外运粪污，不能算作就地资源化利用，达不到种养循环项目的硬性验收条件，示范基地创建工作受阻。
旧模式只做到了“把粪污运走”，没有实现 “就地变肥还田”，种养循环流于形式。基地迫切需要一套可连续运行的无害化烘干成套系统。
II. Pain Points of the Original Disposal Model, Hindering Functional Circular Operations
Before renovation, the base adopted a traditional combination of off‑site transport and open‑air composting, which exhibited numerous drawbacks failing demonstration project standards:
High manure outbound transportation costs: Outsourced daily manure removal faces rising freight charges year on year. In rainy seasons, treatment sites reach saturation, and receivers may refuse acceptance. Manure consumption is fully dependent on external channels.
Lengthy composting cycles and heavy pressure on storage space: Natural compost maturation often takes months and requires large compost yards. The base faces land shortages; rainy‑season compost piles carry risks of leachate seepage and malodour nuisance for residents.
Unstable finished fertiliser quality: Heavily affected by weather, compost maturity varies unevenly. Partial material retains insect eggs and pathogens that survive incomplete sterilisation. Direct field application may introduce pests and diseases alongside fluctuating fertiliser efficiency.
Failure to meet project acceptance criteria: Simple off‑site manure transport is not recognised as on‑site resource utilisation and fails mandatory acceptance requirements for the planting‑breeding circular programme, stalling demonstration base creation.
The old model only moved manure away instead of converting it into fertiliser locally for farmland return, reducing the planting‑breeding circular concept to a formality. The base urgently required a continuously operable complete harmless drying system.

III. Full Implementation of Jinwanhong Horizontal Flash Drying Solution
Based on the base’s daily manure output, site layout and planting‑breeding circular project application requirements, Jinwanhong customised a complete turnkey solution for this layer farm: ✅ Core main unit: Horizontal flash dryer, supporting direct feeding of high‑moisture fresh chicken manure with an integrated breaking‑suspension flash‑drying process. ✅ Supporting systems: Fully enclosed feeding mechanism and integrated dust & odour removal system to eliminate dust and odour leakage within the site. ✅ Heat source system: Heat source configuration matched to on‑site energy conditions to guarantee stable 24/7 continuous equipment operation. ✅ Full delivery package: Pre‑project site survey, customised scheme, on‑site installation & commissioning, operator hands‑on training, plus complete equipment qualifications, test reports and operating condition documentation required for project applications.
The complete set of equipment is installed in the base’s manure treatment workshop with fully enclosed workflows. Fresh chicken manure collected from henhouses feeds directly into the drying system, with no pre‑drying or lengthy pre‑composting required.
四、设备实际运行效果：无害化处理，产出合格有机肥原料
设备投产后，高湿鲜鸡粪直接入机，依托卧式闪蒸动态悬浮烘干 + 高温瞬时灭菌工艺，同步完成脱水、杀菌两大核心环节。
·高效脱除水分，成品干鸡粪含水率稳定可控，物料松散干爽；
·高温杀灭粪污内部虫卵、致病菌，从根源消除成品后期二次发酵、滋生虫害问题；
·有机质得到有效保留，成品品质稳定，完全符合有机肥原料入库标准；
·全密闭负压运行，烘干车间无明显恶臭扩散，解决厂区异味扰民隐患。
整套系统自动化程度高，人工投入少，可以匹配基地每日粪污产出量，做到粪污日产日清，不再出现粪污囤积堆放。
IV. Actual Equipment Operation: Harmless Treatment, Production of Qualified Organic Fertiliser Feedstock
After commissioning, high‑moisture fresh chicken manure is fed directly into the machine. Combining horizontal flash dynamic suspension drying and high‑temperature instant sterilisation, the unit completes two core tasks: dewatering and pathogen elimination.
Efficient moisture removal, with stably controllable moisture content in finished dry chicken manure, forming loose, dry material.
High temperatures kill insect eggs and pathogenic bacteria inside manure, fundamentally eliminating risks of secondary fermentation and pest breeding in finished products.
Organic matter is effectively retained. Consistent finished quality fully satisfies warehousing standards for organic fertiliser raw materials.
Fully sealed negative‑pressure operation prevents obvious malodour diffusion from the drying workshop, resolving odour nuisance risks.
The whole system features high automation and low labour input. It matches the base’s daily manure yield to achieve same‑day disposal, eliminating manure stockpiling.
五、构建真实可落地的种养循环闭环
烘干产出的干鸡粪，基地采用“自用还田 + 对外外销” 双线利用模式，真正实现养殖固废的资源化价值。
1.内部自用还田：一部分干鸡粪直接供给基地自有果蔬、粮食种植基地作为有机肥原料，减少化肥采购投入，改良土壤地力，实现养殖粪肥就地反哺种植；
2.对外市场化销售：富余部分干鸡粪外销至周边有机肥加工厂、果蔬种植合作社，形成稳定的副产品收益，把原本的处置负担转变为项目增量收入。
从蛋鸡养殖产生粪污，经过设备无害化烘干处理，再回归农田土壤，完整的种养循环链路真正运转起来，不再停留在纸面方案。
V. Building a Practical, Operable Planting‑breeding Closed Circular Loop
Dried chicken manure from the dryer follows a dual utilisation strategy of on‑site return + external sales, unlocking resource value from breeding solid waste.
Internal farmland return: Part of the dried manure is directly supplied to the base’s own fruit, vegetable and grain planting plots as organic fertiliser, cutting chemical fertiliser procurement costs and improving soil fertility. This realises local recycling of breeding manure for crop production.
Commercial external sales: Surplus dried manure is sold to nearby organic fertiliser plants and fruit & vegetable planting cooperatives, generating steady by‑product revenue and transforming a costly disposal burden into incremental project income.
The full planting‑breeding circular chain operates in reality: manure generated from layer farming undergoes harmless drying treatment by equipment and is returned to farmland soil, rather than remaining only on paper plans.
六、一套设备，同时满足环保考核+ 种养循环项目双重验收
该项目最大价值，在于一套设备同时承接两大硬性考核要求：
环保维度：实现场内粪污标准化密闭处置，杜绝乱堆乱放、渗滤液溢流、异味扰民，顺利通过多轮环保现场检查，消除基地粪污环保风险。
项目申报维度：实现粪污就地减量化、无害化、资源化利用，满足种养循环示范基地项目建设指标。金万泓配套提供全套设备资质、性能证明材料，支撑项目材料报送与现场核验，项目顺利完成种养循环示范项目验收。
VI. Single Unit Satisfies Dual Acceptance: Environmental Assessment + Planting‑breeding Circular Project
The greatest value of this project lies in one set of equipment fulfilling two mandatory assessment requirements: Environmental compliance: Standardised enclosed on‑site manure disposal eliminates random piling, leachate overflow and odour nuisances. It passed multiple rounds of on‑site environmental inspections and mitigates the base’s manure‑related environmental risks. Project application compliance: It achieves on‑site manure volume reduction, harmless treatment and resource utilisation to meet construction indicators for the planting‑breeding circular demonstration base. Jinwanhong provides complete equipment qualification and performance certification documents to support dossier submission and on‑site verification, enabling successful acceptance of the planting‑breeding circular demonstration project.
七、改造前后对比，样板项目带来的实际改变
改造前：依赖外包清运 + 露天堆肥，处置成本高，堆肥周期长，品质不稳定，种养循环仅停留在概念层面，面临环保与项目申报双重压力。
改造后：粪污场内闭环处理，不受天气季节影响；干粪一部分还田改良自有种植基地，一部分对外销售创造收益；厂区无粪污堆积、无溢流隐患，环保达标，成功通过种养循环示范项目验收。
该项目的模式，对国内大量“养殖 + 配套种植” 的规模化基地具备很强参考意义，证明种养循环不需要复杂高昂工艺，选对烘干设备，就可以低成本打通粪肥还田的 “最后一公里”。
VII. Pre‑vs Post‑renovation Comparison, Tangible Changes from the Benchmark Project
Before renovation: Relied on outsourced manure removal and open‑air composting, with high disposal costs, long composting cycles and unstable product quality. The planting‑breeding circular model existed only conceptually, under dual pressure from environmental supervision and project application.
After renovation: Closed‑loop on‑site manure treatment independent of weather and seasonal changes. Part of dried manure returns to improve the base’s cropland, and surplus material is sold externally for profit. No manure stockpiling or overflow risks on site, environmental standards are met, and the planting‑breeding circular demonstration project passed acceptance.
This project model offers strong reference value for numerous domestic large‑scale “breeding + supporting crop” bases. It proves the planting‑breeding circular economy does not require complex, high‑cost processes. Selecting the right drying equipment enables low‑cost completion of the “last mile” of manure fertiliser return to farmland.
写在最后
越来越多规模化养殖基地已经意识到：种养循环不是简单把粪污拉去地里，核心在于无害化就地处置。如果粪污处理环节缺位，循环农业就只能是纸上蓝图。
