1、 Core advantages and overall planning of the project
The production scale of 5000 tons per year is mainly aimed at county-level
or regional markets, and can effectively handle a large amount of agricultural
waste (such as livestock and poultry manure, crop straw), with good economic and
environmental benefits.
Core advantages:
Wide adaptability of raw materials: The production line can process various
organic solid wastes such as livestock manure, sludge, and crop straw.
Efficient Process Science: Adopting aerobic fermentation as the core
process, utilizing microbial degradation to achieve harmless and stable
treatment.
High degree of automation: key processes from fermentation, crushing to
packaging are mechanized and automated, significantly reducing labor costs.
Product standardization: Through precise process control, ensure that the
nutrients, moisture, and fineness of the final product meet market
standards.
Total investment and expected returns of the project: The total investment
of the production line is mainly focused on the construction of the fermentation
workshop and the procurement of key equipment (such as turntables, crushers, and
automatic packaging machines). The production cost of powdered organic
fertilizer is about 300-500 yuan/ton, and the market price is about 600-900
yuan/ton. The payback period is usually 2-3 years.
2、 Detailed explanation of production process flow
The entire production line follows the scientific path of "pretreatment →
fermentation and maturation → deep processing → finished product", with each
link closely connected.
Raw material pretreatment and ingredients: Mix the main materials (such as
fresh manure and straw) with auxiliary materials (such as mushroom residue and
peat) according to a carbon nitrogen ratio (25:1 to 30:1), and adjust the
initial moisture content to 55% -65% to create the best conditions for
fermentation.
Aerobic fermentation and maturation (core process): The mixed materials are
sent into the fermentation tank. During the regular flipping process of the
stacker, the material undergoes heating (>55 ℃), high temperature (maintained
for 5-7 days to kill pathogens), cooling, and maturation processes within 7-15
days, ultimately transforming into stable, odorless humus.
Crushing and screening: The decomposed material is crushed to the required
particle size by a chain crusher, and then classified by a drum screening
machine. Qualified fine powder enters the next process, while coarse material is
returned for re crushing to ensure uniform product fineness (usually requiring
passing through a 20-60 mesh sieve).
Finished product packaging and storage: After screening, the powdered
organic fertilizer is accurately measured by an automatic quantitative packaging
machine (usually 20kg/bag or 40kg/bag), sewn and sent to the finished product
warehouse for storage.
3、 Core equipment selection and technical parameters
Equipment is the backbone of the production line, and its selection
directly affects production capacity and quality. The following are
recommendations for the configuration of key equipment with an annual production
capacity of 5000 tons.
| 序号 | 设备名称 | 推荐型号/规格 | 关键功能与技术要点 | 参考数量 |
|---|
| 1 | 槽式翻堆机 | 行走跨度4-6米 | 为好氧发酵提供核心动力，实现翻抛增氧、散热、匀质。建议选用液压升降式，动力强劲，翻抛彻底。 | 1台 |
| 2 | 链式粉碎机 | 转子宽度≥800mm | 用于破碎腐熟后结块的物料。链锤结构能有效防粘壁，特别适合湿度稍大的有机物料。 | 1台 |
| 3 | 滚筒筛分机 | 筛筒直径≥1000mm | 分离成品与返料。应配置多层筛网（如12目、40目），实现粗细分级，提升产品外观一致性。 | 1台 |
| 4 | 自动定量包装机 | 称重范围20-50kg | 实现快速、精准的成品包装。应选用配有高精度传感器的机型，支持重量预设与数据统计。 | 1台 |
| 5 | 皮带输送机 | 带宽500-650mm | 连接各生产单元，构成连续流水线。水平与爬坡输送机需组合使用，材质需耐腐蚀。 | 3-4条 |
Important reminder: In the process of equipment procurement and installation, special attention should be paid to the brand and quality of core components such as motors (recommended to use national standard copper wire motors) and reducers. It is recommended to clarify the warranty terms with the equipment supplier (such as a 3-year warranty for core components that are not damaged by human factors), and ensure that all materials (especially those in contact with materials) meet the anti-corrosion requirements.
