Water-soluble fertilizer production process

Water-soluble fertilizer (water-soluble fertilizer) is a fertilizer that completely dissolves in water. Its nutrients exist in the form of ions and can be quickly absorbed and utilized by plant roots. Water-soluble fertilizers are usually specially processed to make them highly soluble and stable in water, and can provide various nutrients required by plants.

Advantages of water-soluble fertilizers

· Rapid absorption

· Precise fertilization

· Avoid soil fixation

· Reduce environmental pollution

Common types of water-soluble fertilizers include single water-soluble fertilizers containing major nutrients such as nitrogen, phosphorus, and potassium, as well as compound water-soluble fertilizers containing multiple nutrients. Water-soluble fertilizers are widely used in modern agricultural production, especially for the production of high-yield crops such as field crops, fruit trees, and vegetables.

Production process of water-soluble fertilizer

1. Raw material processing

Water-soluble fertilizer processing usually uses various fertilizer raw materials, such as urea, ammonium sulfate, diammonium phosphate, etc. Or ferment the raw materials.

2. Crushing process

Crush the bulk raw materials to facilitate the subsequent more efficient mixing process.

3. Weighing and mixing process

Raw materials can be weighed and measured by an automatic batching machine according to the formula ratio, and 2-8 different raw materials can be configured. Then the various fertilizer raw materials are transported to the mixing and stirring place for uniform mixing to ensure uniform nutrient distribution.

In this way, the powdered water-soluble fertilizer is completed. To obtain granular water-soluble fertilizer or liquid fertilizer, one more step of processing is required.

Granular water-soluble fertilizer: Powdered water-soluble fertilizer can be combined with granulation to obtain granular water-soluble fertilizer. It is usually recommended to choose a double-roll extrusion granulator, which uses a dry granulation method and is more suitable for the characteristics of water-soluble fertilizer that is easily soluble in water.

Liquid fertilizer: The liquid fertilizer production line is a new type of fertilizer processing equipment, including batching, mixing, filling, metering and packaging. The mixed water-soluble fertilizer is thrown into the liquid fertilizer mixing tank, dissolved and stirred, and filled into a bottled liquid fertilizer of a specified capacity.

During the entire production process, it is very important to strictly control each fertilizer production step, select anti-corrosion equipment, and ensure the quality and safety of fertilizers. At the same time, continuous improvement of process flow and production efficiency are also key.
