【引言】
每到北方冬季，低温霜冻就成为规模化养鸡场的一大环保考验。气温持续走低，鸡粪极易结冰板结，常规脱水手段完全失效，场内粪污越积越多。冬季又是环保常态化巡查的重点时段，粪污堆积、异味外溢，随时面临整改通知。如何破解冰冻鸡粪处置难题，平稳度过冬季环保管控期，是北方养殖场每年都要面对的硬核难题。
Every winter in northern China, low temperatures and frost pose a major environmental compliance challenge for large-scale chicken farms. As temperatures keep dropping, chicken manure easily freezes and hardens, rendering conventional dewatering methods completely ineffective. Manure stockpiles on site keep growing. Winter is also a peak period for routine environmental inspections. Piled manure and odour leakage may trigger rectification notices at any time. Solving the problem of frozen chicken manure disposal and safely navigating the winter environmental supervision period is a tough annual challenge for northern breeding farms.
一、冬季低温环境，鸡粪冻块板结，粪污积压成行业通病
进入冬季低温冰冻期，刚产出的鲜鸡粪含水量高，一旦在露天或者简易棚内存放，很快就会冻成硬块。冻实的粪块内部锁水，常规方式很难剥离、脱水。鸡场持续产粪，处理速度跟不上产出速度，场区粪污存量越堆越高，占用大量场地。
冰冻只是表面问题，待气温小幅回升，冻块融化后会大量渗流，污水漫流、恶臭集中释放，越冬虫卵、病菌藏匿在粪块之中，等到开春气温回升大量繁殖，埋下来年蚊虫、疫病隐患。
I. Frozen and hardened chicken manure under low winter temperatures: manure stockpiling becomes a widespread industry headache
When the cold freezing season arrives, freshly produced chicken manure has high moisture content. If stored in the open air or simple sheds, it quickly hardens into solid blocks. Water is trapped inside the frozen lumps, making separation and dewatering extremely difficult with conventional approaches. Farms continuously generate manure while processing capacity fails to keep pace with output, resulting in expanding stockpiles that occupy large areas of land.
Freezing is only a surface issue. When temperatures rise slightly, thawed lumps produce massive seepage, causing overflow of wastewater and concentrated release of foul odours. Overwintering insect eggs and pathogens hide within the manure blocks. When spring temperatures climb, they multiply rapidly, creating hidden risks of insect infestations and livestock diseases for the coming year.
二、晾晒、堆肥冬季全面失效，粪污积压极易触发环保整改
很多养殖场夏秋季节依靠晾晒、静态堆肥处理鸡粪，这套方案到冬天基本失灵。
露天晾晒：气温低、日照短，水分很难蒸发；粪污直接冻成硬块，完全无法晾晒脱水。一旦积雪覆盖，粪污和冰雪混在一起，后续处置难度成倍增加。
堆肥发酵：低温抑制微生物活性，堆肥升温困难，发酵周期大幅拉长，无法快速消纳粪污。大量粪污长期堆存，属于环保监管重点问题。冬季环保检查、群众信访举报频发，一旦现场核查发现粪污无序堆积、渗滤液外流，养殖场将收到限期整改通知，甚至产生行政处罚。
II. Sun-drying and composting fully ineffective in winter; manure stockpiling easily triggers environmental rectification
Many farms rely on sun-drying and static composting for chicken manure treatment in summer and autumn, yet this approach largely fails in winter.
Open-air sun-drying: Low temperatures and short daylight hours make moisture evaporation difficult. Manure freezes solid and cannot be dehydrated by sun exposure. Once covered by snow, manure mixes with ice and snow, exponentially increasing the difficulty of subsequent disposal.
Compost fermentation: Low temperatures suppress microbial activity, making it hard for compost piles to heat up. Fermentation cycles are greatly extended, and manure cannot be processed rapidly. Long-term stockpiling of large volumes of manure is a key concern for environmental regulators. Environmental inspections and public complaints frequently occur in winter. If on-site checks discover disorderly manure accumulation or leachate outflow, farms will receive rectification orders with deadlines, and may even face administrative penalties.
三、卧式闪蒸高温强制脱水，不受寒冬天气制约，化冻烘干同步完成
金万泓卧式闪蒸烘干机，采用高温强制脱水工艺，不受室外低温、冰冻天气限制。冻块鸡粪送入设备，在内部强力打散结构作用下破碎，配合高温热风快速完成化冻与脱水，一步实现物料干燥，同时杀灭粪污内越冬虫卵、致病菌，从源头减少养殖场疫病传播风险。
整套工艺不依赖自然光照、环境温度，寒冬也可以保持稳定产能，持续消纳每日产出鸡粪，不让粪污在场区长期堆积滞留。
III. Horizontal flash dryers with high-temperature forced dewatering, unaffected by harsh winter weather; thawing and drying completed in one step
Jinwanhong horizontal flash dryers adopt high-temperature forced dewatering technology and are not restricted by low outdoor temperatures or freezing weather. Frozen chicken manure blocks are fed into the machine and crushed by the built-in high-power breaking mechanism. Combined with high-temperature hot air, thawing and dewatering are completed rapidly in one pass to dry the material. Meanwhile, overwintering insect eggs and pathogenic bacteria inside the manure are killed, reducing the risk of disease transmission on farms at the source.
The entire process does not depend on natural sunlight or ambient temperature. Stable production capacity can be maintained even in severe cold to continuously handle daily chicken manure output and prevent long-term manure accumulation on site.
四、全密闭负压作业，冬季厂房封闭，异味不外溢，村落周边养殖也合规
冬季天气寒冷，养殖场厂房门窗大多长期关闭，空气流通差。如果粪污处理设备密闭性不足，异味容易积聚在厂区内部，甚至扩散到周边村落，引发邻里投诉。
卧式闪蒸整套系统采用全密闭负压设计，烘干全过程在密闭腔体内部完成，臭气、粉尘被统一收集处理。即便冬季厂房密闭，异味也不会向外窜溢，紧邻村庄的规模化养殖场同样可以稳定合规生产，规避异味信访风险。
IV. Fully enclosed negative-pressure operation: with farm workshops kept closed in winter, odour is contained for compliant farming near villages
In cold winter, farm workshops mostly keep doors and windows closed for long periods, leading to poor air circulation. If manure treatment equipment lacks adequate sealing, odour tends to build up inside the plant and may spread to surrounding villages, triggering complaints from residents.
The full horizontal flash drying system adopts a fully enclosed negative-pressure design. The entire drying process takes place inside a sealed chamber, with odour and dust collected and treated centrally. Even with closed workshops in winter, odour will not escape outwards. Large-scale farms located close to villages can maintain stable and compliant production and avoid odour-related complaints.
五、干料干爽松散不易返潮，冬季集中储备，打通全年资源化链路
经过卧式闪蒸处理后的干鸡粪，成品干爽松散，含水率稳定可控，冬季低温环境下不易吸潮返潮、二次结块。养殖场可在冬季持续生产，大量储备干鸡粪成品。
等到开春种植旺季，储备好的干粪原料可直接用于还田或者外销有机肥厂，解决冬季粪污没法处理、资源化生产中断的痛点，保障养殖场全年粪污资源化收益稳定。
V. Dry material is loose and resistant to rewetting; winter stockpiling enables year-round resource utilisation chains
Dried chicken manure processed by horizontal flash dryers is loose and dry with stably controllable moisture content. It resists moisture absorption and secondary caking under low winter temperatures. Farms can run production continuously in winter and stockpile large quantities of finished dried manure.
When the spring planting season arrives, the stockpiled dried manure can be directly returned to farmland or sold to organic fertiliser plants. This resolves the pain point of interrupted resource utilisation due to unprocessable manure in winter and guarantees stable annual revenue from manure resource utilisation for farms.
六、两套落地方案，适配北方养殖场应急清污与常态化治理
方案一：冬季应急清污方案
针对已经出现大量粪污冻块积压的鸡场，可配套卧式闪蒸成套设备快速消纳存量冻粪，短期内清空堆场，快速完成环保整改，化解突击检查风险。
方案二：全年常态化环保治理方案
按照养殖场日常粪污产生量，匹配对应规格卧式闪蒸烘干产线，日产日消，从源头杜绝粪污堆积，一年四季稳定达标，不再受冬夏季节变化影响，实现长期稳定环保运维。
VI. Two practical implementation plans for northern farms: emergency manure clearance and year-round regular management
Plan 1: Winter emergency manure clearance For chicken farms already facing massive stockpiles of frozen manure blocks, complete horizontal flash drying equipment can be deployed to rapidly consume the accumulated frozen manure, clear stockyards in a short time, complete environmental rectification quickly and mitigate risks from surprise inspections.
Plan 2: Year-round regular environmental management A horizontal flash drying production line sized to match the farm’s daily manure output is deployed to achieve same-day generation and same-day disposal. This eliminates manure accumulation at the source, maintains stable compliance all year round regardless of seasonal changes, and enables long-term stable environmental operation and maintenance.
七、北方高寒场区真实落地案例，冬季连续稳定运行，实现环保零处罚

VII. Real project case in alpine northern zones: continuous stable winter operation with zero environmental penalties
Large-scale layer breeding bases in multiple cold northern regions suffer from long cold winters and frequent wind and snow. They were once plagued by frozen chicken manure disposal, with repeated reminders from environmental authorities over stockyard manure accumulation.
After installing the complete Jinwanhong horizontal flash manure drying production line, the equipment runs nonstop through winter. Frozen chicken manure can be fed directly for treatment. No large stockpiles of fresh manure remain on site, odour control meets standards, and the farm has smoothly passed environmental inspections for multiple consecutive winters, achieving zero environmental penalties. The dried chicken manure produced by drying is sold steadily, generating extra project revenue while solving environmental issues.
For winter manure disposal on northern farms, selecting the right equipment relieves seasonal environmental pressure. Jinwanhong Machinery provides on-site working condition surveys, free material test runs, and customised complete chicken manure drying solutions tailored for alpine environments to help farms get through winter smoothly.
