Henan Hongke Heavy Machinery Co., Ltd. has delivered a Φ2×8m rotary dryer production line for chicken manure drying to a customer in Chengde, Hebei Province, China. The line converts wet chicken manure into a dried, stable material suitable for organic fertilizer production and safe storage.
This article covers the full project: customer background, the original problem, equipment configuration, delivery timeline, commissioning results, and customer feedback.
1. Customer Background
Location: Chengde, Hebei Province, China
Industry: Organic fertilizer / agricultural waste processing
Chengde sits in northern Hebei, a region with active poultry farming and a growing demand for organic fertilizer. Chicken manure is a valuable nutrient source, but its high moisture content—typically 60–75% as excreted—makes it difficult to store, transport, and process. Drying is the critical first step before composting, pelletizing, or sale as organic fertilizer.
Our customer is an agricultural waste processor in Chengde. They collect chicken manure from nearby poultry farms and wanted to establish a drying line to produce a stable, saleable organic fertilizer feedstock. The selected model was a Φ2×8m rotary dryer.
2. The Original Problem
Before approaching Henan Hongke Machinery, the customer faced several practical constraints:
| Problem | Impact |
|---|---|
| High moisture content | Raw manure was heavy, sticky, and prone to rapid decomposition |
| Odor and leachate | Storage and transport created environmental and neighbor complaints |
| Inconsistent drying | Sun drying was weather-dependent; output moisture varied |
| Material sticking | Wet manure adhered to equipment, causing blockages and stoppages |
| Corrosion risk | Moisture and ammonia accelerated equipment wear |
| Throughput target | Needed a continuous line matched to daily manure collection volumes |
The customer needed a purpose-built rotary dryer—not a modified grain dryer—configured for the sticky, high-moisture characteristics of chicken manure.
3. Why the Customer Chose Henan Hongke Machinery
After evaluating several suppliers, the customer selected us for specific, practical reasons:
a) Experience with high-moisture organic materials
Chicken manure is not a free-flowing material. It is sticky, variable in moisture, and corrosive due to ammonia. We discussed these characteristics during technical exchange and designed the dryer internals accordingly—not just quoted a standard unit.
b) Custom internal structure to prevent sticking
We specified a lifting-flight arrangement and chain/breaker configuration suited to sticky manure, reducing build-up inside the drum and maintaining continuous material flow.
c) Complete line responsibility
We supplied the full scope: feed system, Φ2×8m rotary dryer, heating system, discharge conveying, dust and odor control provisions, and control panel. The customer did not have to coordinate multiple suppliers.
d) Corrosion-conscious construction
Given ammonia and moisture exposure, we selected materials and coatings appropriate for the duty, and specified accessible inspection points for maintenance.
e) Long-term support commitment
The customer wanted a supplier available for commissioning support, spare parts, and process advice after handover.
4. Equipment Configuration
