The straw organic fertilizer production line is a professional production line that uses crop straw as the main raw material and converts it into efficient organic fertilizer through a series of processing and treatment. This production line can not only effectively utilize a large amount of agricultural waste, reduce environmental pollution, but also improve soil fertility and promote sustainable agricultural development. The following is an overview of the main equipment and their functions required for processing fertilizers in straw organic fertilizer production lines:

1. Raw material preparation stage

Straw chopper: Cut long fiber straw into small pieces suitable for fermentation to improve fermentation efficiency.

Raw material mixer: Mix chopped straw evenly with animal manure, bacterial strains, and other auxiliary materials (such as limestone powder, phosphate, etc.), adjust the carbon nitrogen ratio, and prepare for fermentation.

2. Fermentation stage

Fermentation bed turning machine: It flips materials on an open fermentation bed, providing sufficient oxygen to maintain the normal progress of the fermentation process.

Fermentation tank: For indoor enclosed fermentation, a fermentation tank is used to accelerate the fermentation process by controlling temperature, humidity, and oxygen supply.

Fermentation starter microbial agent: Although not a device, it is the key to starting fermentation, which can effectively shorten fermentation time and improve fermentation efficiency.

3. Screening and crushing stage

Vibration screen: used to remove large particles and impurities from the fermented mixture, such as incompletely decomposed straw segments.

Organic fertilizer pulverizer: further pulverize the screened materials to form small particles, which facilitate granulation and improve fertilizer uniformity.

4. Drying stage

Drying machine: Drying the crushed material to control its moisture content and meet the standards suitable for granulation and storage.

5. Granulation stage

Organic fertilizer granulator: By squeezing, rolling, and other methods, the dried powdered organic fertilizer raw materials are made into granules for easy storage, transportation, and use.

Cooling machine: The fertilizer granules after granulation need to be quickly cooled to prevent clumping and maintain shape integrity.

6. Packaging stage

Automatic packaging machine: automatically measures, fills, and seals the cooled organic fertilizer particles to complete the packaging work of the finished product.

7. Auxiliary equipment and others

Conveyor belt: connects the material transfer between various devices to improve the overall operational efficiency of the production line.

Dust collector: used to capture and filter the dust generated in the production line, keep the workshop clean, and reduce pollution.

Automated control system: monitors and adjusts various parameters on the production line, such as temperature, humidity, oxygen concentration, etc., to ensure the stability of the production process and the consistency of product quality.

To build a complete straw organic fertilizer production line, it is necessary to select suitable equipment models and configurations based on specific production scale, types of raw materials, expected production capacity, and other factors. At the same time, it is also very important to consider the energy consumption, maintenance costs, and the possibility of future upgrades of the equipment.
