【引言】
不少规模化养殖场早年配套了鸡粪烘干设备，投产多年后逐步陷入各种棘手问题：频繁粘壁堵料、出料干湿不均、能耗居高不下，配套环保系统压力大，异味超标，环保检查反复预警。想要直接整套拆除重建，厂房布局受限、基建投入巨大、停工周期长，严重影响场内粪污常态化处置。原位技改升级，成为老旧产线最经济高效的破局方案。
Many large-scale breeding farms installed chicken manure drying equipment in the early years. After years of operation, they have gradually encountered a host of thorny issues: frequent wall adhesion and material blockages, inconsistent moisture content of discharged materials, persistently high energy consumption, heavy load on supporting environmental protection systems, excessive odour, and repeated warnings during environmental inspections. A complete demolition and reconstruction would be constrained by plant layout, require massive capital investment in infrastructure and entail a lengthy shutdown period, severely disrupting regular on-site manure disposal. In-situ technical upgrading has become the most cost-effective and efficient solution for ageing production lines.
一、老旧烘干设备普遍四大通病，长期拖累养殖场运营
运行多年的老式滚筒、简易烘干设备，大多存在先天工艺短板，日积月累问题集中爆发：
粘壁堵料频发：高湿鸡粪极易粘附筒壁，结块堆积，每隔一段时间就要停机人工清理，占用大量人工，频繁中断生产；
成品含水不达标：换热效率差，物料烘不透，出料夹生，含水率波动大，产出干粪达不到有机肥原料收购标准，外销受阻，存储还容易二次发酵；
能耗长期偏高：设备热损耗大，燃料消耗高，单位吨料处理成本居高不下，越生产越不划算；
环保指标不达标：密封性能衰减，粉尘、异味外泄，除臭除尘系统超负荷运行，容易触发环保督查、群众信访，整改压力持续存在。
很多养殖场陷入两难：继续使用，故障多、能耗高、环保风险大；整套拆掉重建，厂房、地基、管线全部重来，投资大、停产时间久。原位主机替换技改，不用大拆大建，解决老产线痛点。
I. Four Common Defects of Ageing Drying Equipment, Long Draining Farm Operations
Most old drum and simple drying equipment that has run for years suffers inherent process flaws, and accumulated problems break out intensively:
Frequent wall adhesion and blockages: High-moisture chicken manure easily sticks to the cylinder wall and forms clogs. Shutdowns are required regularly for manual cleaning, consuming substantial labour and repeatedly interrupting production.
Non-compliant moisture content of finished products: Poor heat exchange efficiency leads to incompletely dried material and undercooked discharge with volatile moisture levels. The resulting dried manure fails to meet purchase standards for organic fertiliser raw materials, blocking external sales and prone to secondary fermentation during storage.
Sustained high energy consumption: Heavy heat loss and high fuel consumption keep the processing cost per ton of material high, making production increasingly uneconomical.
Substandard environmental indicators: Sealing performance degrades, causing dust and odour leakage. The de-dusting and deodorisation systems operate under overload, easily triggering environmental inspections and public complaints with persistent rectification pressure.
Many farms face a dilemma: continued operation brings frequent breakdowns, high energy use and substantial environmental risks; full demolition and reconstruction means rebuilding workshops, foundations and pipelines with heavy investment and long downtime. In-situ main unit replacement upgrades avoid large-scale demolition and construction and resolve pain points of old production lines.
二、无需推倒重建、不用新建厂房，原位替换金万泓新型烘干主机
原位技改核心优势：保留原有厂房基础，只对核心烘干主机进行替换，不需要大规模土建施工。金万泓可根据原有场地空间、地基尺寸、设备布局，定制卧式闪蒸烘干主机，适配原有空间位置，直接替换老旧主机。
不用扩建车间、不用重新做大面积地基改造，最大程度规避土建大额投入。改造期间分段施工，合理安排工期，尽可能缩短停产时间，保障养殖场粪污处置不中断。
II. No Need for Demolition or New Workshop Construction; Replace the Old Unit with a New Jinwanhong Drying Host In Situ
Core advantages of in-situ technical transformation: retain the original workshop foundation and only replace the core drying host without large-scale civil engineering. Based on the original site space, foundation dimensions and equipment layout, Jinwanhong customises horizontal flash drying hosts to fit the original location and directly replace ageing units.
No workshop expansion or extensive foundation retrofitting is required, largely avoiding huge civil engineering costs. Construction proceeds in phases during the renovation period with a well-planned schedule to minimise shutdown time and ensure uninterrupted manure disposal for the farm.
三、技改前后全方位数据对比，产能、能耗、环保同步升级
完成原位技改之后，产线多维度指标实现升级：
✅ 日处理产能：新型主机打散+悬浮烘干工艺，同等占地面积下，粪污处理能力提升，可匹配养殖场现有粪污产出规模，消除粪污积压；
✅ 人工成本：从频繁停机清堵，变为长期稳定连续生产，大幅减少人工清理、检修工时，人工支出显著下降；
✅ 燃料能耗：换热效率提升，热量利用率更高，处理每吨鸡粪燃料消耗降低，长期运营持续节约燃料成本；
✅ 环保合规度：新主机全密闭负压结构，粉尘、臭气可控，减轻原有除尘除臭系统负荷，稳定达标，降低信访与处罚风险。
III. Comprehensive Data Comparison Before and After Renovation: Simultaneous Upgrades in Capacity, Energy Consumption and Environmental Performance
After completing in-situ technical transformation, multi-dimensional indicators of the production line are improved: ✅ Daily processing capacity: Adopting the breaking and suspension drying process of the new host, manure handling capacity rises within the same footprint. It matches the farm’s existing manure output and eliminates manure stockpiling. ✅ Labour cost: Frequent shutdowns for blockage clearing are replaced by stable long-term continuous production, greatly cutting working hours spent on manual cleaning and maintenance and significantly lowering labour expenditure. ✅ Fuel energy consumption: Improved heat exchange efficiency and higher heat utilisation reduce fuel consumption per ton of chicken manure, delivering continuous fuel cost savings over long-term operation. ✅ Environmental compliance: The new host adopts a fully enclosed negative-pressure structure for controllable dust and odour, easing the load on the original dust and odour removal systems. Stable compliance reduces risks of public complaints and penalties.
四、兼容原有配套系统，改造成本更低、施工更快、投产周期短
原位技改方案最大亮点，是充分利旧。新主机可对接养殖场原有上料输送、热源、除尘除臭、出料仓储整套配套系统，原有管线、料仓、引风装置评估合格后可继续沿用，不需要全部换新。
利旧配套设施，直接砍掉大量辅机采购费用，整体改造成本远低于新建整套产线。现场模块化施工，工期紧凑，改造完成后快速调试投产，短时间内恢复粪污资源化生产。
IV. Compatible with Original Supporting Systems: Lower Renovation Cost, Faster Construction and Shorter Commissioning Cycle
The biggest highlight of the in-situ renovation plan is maximising reuse of existing facilities. The new host can connect to the farm’s original feeding and conveying, heat source, dust and odour removal, and discharging and warehousing systems. Qualified original pipelines, silos and air induction devices can remain in service instead of full replacement.
Reusing auxiliary facilities drastically cuts procurement costs for auxiliary machinery. The overall renovation cost is far lower than building a complete new production line. Modular on-site construction ensures a tight schedule. After renovation, commissioning and production startup can be completed rapidly to resume resource-oriented manure treatment in a short time.
五、技改项目可对接2026养殖设备升级补贴，降低投入成本
2026畜禽粪污资源化技改扶持政策中，养殖场粪污处理设备升级改造项目，属于政策支持范畴。原位主机替换技改项目，符合粪污无害化、资源化改造申报方向。
金万泓全系卧式闪蒸设备资质齐全，配套完整检测报告、设备资料，可协助客户整理项目申报材料，对接地方主管部门验收，争取技改专项补贴，进一步压低技改投入，提升项目投资回报率。
V. Renovation Projects Qualify for 2026 Livestock Equipment Upgrade Subsidies to Reduce Investment
Under the 2026 supporting policies for technical transformation of livestock and poultry manure resource utilisation, upgrading projects for farm manure treatment equipment fall within the scope of policy support. In-situ main unit replacement renovation projects align with the application direction for harmless and resource-oriented manure transformation.
Jinwanhong’s full range of horizontal flash dryers come with complete qualifications, supporting test reports and equipment documentation. We assist customers in organising project application materials, coordinating acceptance with local competent authorities and applying for special technical transformation subsidies to further lower renovation investment and raise project return on investment.
六、老旧养殖场技改落地真实案例，改造前后效果对比
山东多家规模化蛋鸡场，原有老式滚筒烘干设备使用多年，常年粘筒堵料，出料品质不稳定，异味问题多次收到环保提醒。经过现场勘测评估，采用原位主机替换技改方案，保留原有上料、除尘、料仓配套，更换金万泓卧式闪蒸烘干主机。
技改完成后，堵料粘壁问题得到根治，产线可以长时间连续运行，人工清理工作量大幅减少，出料含水率稳定达标。厂区异味得到有效管控，顺利通过环保核查；干鸡粪品质提升，外销价格更加稳定。项目同步完成技改补贴申报，有效降低本次升级投入。
VI. Real Case of Technical Transformation for Ageing Farms, Performance Comparison Before and After Renovation
Multiple large-scale layer farms in Shandong had operated old drum drying equipment for years, plagued by persistent cylinder sticking and blockages and unstable output quality. Odour issues triggered multiple environmental reminders. After on-site survey and evaluation, the in-situ main unit replacement solution was adopted: original feeding, dust removal and silo supporting facilities were retained, and the Jinwanhong horizontal flash drying host was installed.
After renovation, sticking and blockage problems were fully resolved, enabling long continuous production line operation and drastically reducing manual cleaning workload. The moisture content of output materials remains stably up to standard. On-site odour is effectively controlled, and environmental inspections are passed smoothly. Improved dried chicken manure quality delivers more stable sales prices. The project also successfully applied for technical transformation subsidies, effectively reducing the upgrade investment.
