Why should chicken manure be dried? ——Analysis of the economic and environmental value of drying treatment
Recently, agricultural environmental protection and resource reuse have become hot topics, among which chicken manure drying technology has attracted much attention due to its significant economic and environmental benefits. This article will combine the hot data of the entire network in the past 10 days to conduct a structured analysis of the necessity of drying chicken manure and compare the advantages and disadvantages of traditional processing methods.
1. The core reasons for drying chicken manure
Chicken manure drying is the process of converting wet chicken manure into dry organic fertilizer or feed ingredients by evaporating water at high temperatures. Its main purposes include:
| reason | illustrate | Data support |
|---|---|---|
| reduce pollution | Wet chicken manure can easily breed bacteria and release ammonia gas | Pathogen inactivation rate after drying is >90% |
| Improve transportation efficiency | Moisture content dropped from 70% to less than 15% | Volume reduced by 60% |
| Easy to store | Avoid mildew and nutrient loss | Shelf life extended to 1 year |
| Increase added value | Can be processed into organic fertilizer or feed | The price increases 2-3 times after drying |
2. Comparison of drying processes (hot search data in the past 10 days)
| Processing method | Energy consumption (kWh/ton) | processing cycle | Hot search index |
|---|---|---|---|
| Natural drying | 0 | 5-7 days | 1520 |
| tumble drying | 80-100 | 2-3 hours | 4870 |
| Solar drying | 15-20 | 1-2 days | 3560 |
| Microwave drying | 120-150 | 30 minutes | 2180 |
3. Environmental protection policies and market demand
According to the latest notification from the Ministry of Ecology and Environment, the resource utilization rate of livestock and poultry manure is required to reach more than 75% in 2023. Recent e-commerce platform data shows:
| product type | monthly sales growth rate | Price per customer (yuan/ton) |
|---|---|---|
| Drying chicken manure | +42% | 800-1200 |
| Untreated chicken manure | -15% | 200-300 |
4. Typical case analysis
After a breeding enterprise in Shandong adopted drying equipment:
| index | before processing | After processing |
|---|---|---|
| Daily processing volume | 10 tons (moisture content 70%) | 3 tons (moisture content 12%) |
| annual income | 720,000 yuan (direct sales) | 2.6 million yuan (deep processing) |
| Number of complaints | 23 times/year (stinky smell) | 0 times |
5. Future development trends
Combined with recent industry trends, chicken manure drying technology will present three major directions:
1.Energy synergy: Thermal energy recovery system combined with biogas power generation (the Douyin-related video has been played more than 5 million times)
2.Intelligent control: Automatic temperature and humidity adjustment based on the Internet of Things (Baidu Index +37% week-on-week)
3.Zero emissions: Search volume for exhaust gas treatment devices increased by 120% monthly
To sum up, chicken manure drying is not only a necessity for environmental protection, but also an important starting point for the transformation and upgrading of the breeding industry. With the advancement of technology and the promotion of policies, this field will continue to release greater economic and environmental value.
