Cow Dung Dryer

Product Name: Cow Dung Dryer

Product Description: Cow Dung Dryer

The Cow Dung Dryer (also known as Chicken Manure Dryer, Duck Manure Dryer, Horse Manure Dryer) is suitable for large, medium, and small-scale farms, as well as developed regions in the livestock industry. Depending on the drying requirements, different heat sources can be used, such as gas generators, direct-fired hot air furnaces, indirect-fired hot air furnaces, heat-conducting oil, electric heating, and steam, among others.

1. Raw Material

Cow dung contains 14.5% organic matter, 0.30-0.45% nitrogen, 0.15-0.25% phosphorus, and 0.10-0.15% potassium. It is a valuable resource used in agriculture as a source of soil fertilizer. Cow dung has the lowest organic matter and nutrient content among various livestock, with a fine texture and higher moisture content. It decomposes slowly and generates low heat, making it a slow-release fertilizer. Compared to chicken manure and pig manure, cow dung has much lower nutrient content (nitrogen, phosphorus, potassium), and its decomposition rate is slower. Therefore, its fertilizing effect is much slower than chicken manure and pig manure.

2. Usage

After being dried by the Cow Dung Dryer (Chicken Manure Dryer, Duck Manure Dryer, Horse Manure Dryer), the dried cow dung can be used as a nutrient substrate for cultivating edible mushrooms or sold as feed for turtle, fish, snail, chicken, and ducks, among others.

3. Scope

This machine is suitable for drying cow dung, chicken manure, duck manure, poultry manure, and slaughterhouse waste with a moisture content of less than 65%.

4. Prospects

The Cow Dung Dryer plays a crucial role in developing feed resources, reducing breeding costs, and minimizing environmental pollution.

Mechanical Structure and Working Principle of the Cow Dung Dryer 

The Cow Dung Dryer (Chicken Manure Dryer, Duck Manure Dryer, Horse Manure Dryer) mainly consists of a heat source, feeding machine, conveyor, rotary drum, material crushing device, discharge machine, induced draft fan, discharger, and distribution cabinet. After the dehydrated wet material is added to the dryer, it is evenly distributed and comes into contact with hot air through the turning plates inside the drum, allowing for faster drying and heat transfer. During the drying process, the material is discharged as finished product through a star-shaped discharge valve at the other end of the dryer, aided by the inclined plates and hot airflow.

Key Features of the Cow Dung Dryer

1. Production Process: The machine dries fresh cow dung with a moisture content of 65% through high-temperature drying, sterilization, and decomposition processes, resulting in pure cow dung organic fertilizer with a moisture content below 13%.

2. Dried Product: The organic fertilizer contains various essential nutrients required for crops. According to laboratory tests, the fertilizer has a nitrogen content of 2.6%, phosphorus content of 3.5%, potassium content of 2.5%, crude protein content of 16-25%, and organic matter content of 45%. It is the best choice for environmentally friendly and green food cultivation and can also be used for feeding fish, cows, pigs, and other animals.

3. The rotary drum dryer has high mechanization, large production capacity, and can operate continuously.

4. It has a simple and excellent structure, with smooth material flow and easy operation.

5. The machine requires minimal maintenance, with low maintenance costs and power consumption.

6. It has a wide range of applications and provides uniform drying of products.

7. It can achieve sterilization and deodorization while drying.
