The production of Di ammonium Phosphate involves a precise chemical reaction followed by granulation and drying processes, ensuring a consistent and high-quality product. Fizachem employs advanced manufacturing techniques to produce superior DAP, adhering to stringent quality control at every stage. The core manufacturing process can be visualized as follows:

Manufacturing Process Overview: From Raw Materials to Granular DAP

1. Raw Material Preparation:
   • Phosphoric Acid (H₃PO₄): Sourced from phosphate rock, it's typically produced via the wet process (reaction of phosphate rock with sulfuric acid) and concentrated to the required strength (e.g., 40-54% P₂O₅).
   • Ammonia (NH₃): Supplied as anhydrous ammonia, it's a gas that is carefully stored and metered for the reaction.
2. Reaction Phase (Ammoniation):
   • Description: Phosphoric acid and gaseous ammonia are reacted in a specialized pre-neutralizer or reactor. This highly exothermic reaction forms a slurry of monoammonium phosphate (MAP) and diammonium phosphate (DAP).
   • Key Node: pH control is crucial here. The pH is carefully maintained between 5.8-6.0 for efficient DAP formation, moving towards 7.8-8.2 in the granulator, ensuring the correct stoichiometric ratio of ammonia to phosphoric acid to maximize the yield of DAP (NH₄)₂HPO₄ and minimize the formation of monoammonium phosphate (NH₄)H₂PO₄.
   • Equation: H₃PO₄ + 2NH₃ → (NH₄)₂HPO₄ (simplified)
3. Granulation:
   • Description: The hot, concentrated slurry from the reactor is then transferred to a granulator (e.g., a rotating drum granulator or a pugmill). Recycled fine particles (oversize and undersize from screening) are added to the granulator to act as nuclei for new granules. Water is sprayed to facilitate the agglomeration of particles into uniform granules.
   • Key Node: Granule formation and size control. Parameters like feed rate, recycle ratio, and water addition are meticulously controlled to achieve the desired particle size distribution, typically 2-4 mm, which is ideal for spreading and nutrient release.
   • Manufacturing Process Note: Unlike metal components which use casting or forging, DAP production utilizes a chemical reaction followed by granulation to form solid particles. This process demands precision in chemical engineering and material handling.
4. Drying:
   • Description: The wet granules from the granulator are fed into a rotary dryer, where hot air flows counter-currently to reduce the moisture content.
   • Key Node: Moisture content reduction. Optimal drying ensures product stability, prevents caking during storage, and maintains granule integrity. The target moisture content is typically less than 1.5%.
5. Screening:
   • Description: Dried granules are passed through screens to separate them into desired size fractions. Oversize granules are crushed and recycled, while undersize fines are also recycled back to the granulator.
   • Key Node: Particle size uniformity. This step guarantees that the final product meets stringent particle size specifications, crucial for efficient spreading and uniform nutrient distribution in the field.
6. Cooling:
   • Description: The correctly sized granules are then cooled in a rotary cooler to bring their temperature down to ambient levels, preventing caking and ensuring safe storage.
   • Key Node: Temperature control for stability. Rapid cooling enhances granule hardness and reduces moisture reabsorption.
7. Coating (Optional but Recommended):
   • Description: Some manufacturers apply a thin layer of anti-caking agent to the cooled granules to prevent clumping during storage and transport, especially in humid conditions.
   • Key Node: Enhanced storage and handling. This step significantly improves the product's shelf life and usability.
8. Packaging and Storage:
   • Description: The finished Di ammonium Phosphate DAP is conveyed to storage silos or directly to packaging lines, where it is bagged in various sizes (e.g., 50kg bags, bulk bags) or prepared for bulk shipment.

Throughout this process, stringent quality control measures are applied, including regular chemical analysis, particle size distribution checks, and moisture content testing, to ensure the final product consistently meets or exceeds ISO and industry standards.

Frequently Asked Questions (FAQ) about Di ammonium Phosphate

To provide further clarity and enhance trust, here are answers to some common questions regarding Di ammonium Phosphate:

Q1: What is the primary use of Di ammonium Phosphate (DAP)?

A1: The primary use of Di ammonium Phosphate is as a highly effective, granular fertilizer in agriculture. It provides both phosphorus (P) and nitrogen (N) which are essential macronutrients for plant growth, particularly important for root development, flowering, and overall plant vigor across a wide range of crops.

Q2: What is the typical nutrient analysis of DAP?

A2: Standard Di ammonium Phosphate has a nutrient analysis of 18-46-0. This means it contains 18% nitrogen (N) and 46% available phosphorus (P₂O₅), with 0% potassium (K₂O). The nitrogen is present as ammonium nitrogen (NH₄⁺), and the phosphorus is in the form of phosphate (HPO₄²⁻).

Q3: Is DAP safe for all crops?

A3: Yes, DAP is generally safe and highly effective for most crops. However, it is slightly alkaline (pH around 7.8-8.2), which can be beneficial in acidic soils. Care should be taken when applying it close to germinating seeds or young seedlings, as high concentrations of ammonia released during dissolution can cause seedling burn if not properly managed (e.g., placed away from the seed row or incorporated into the soil).

Q4: How should Di ammonium Phosphate be stored?

A4: Di ammonium Phosphate should be stored in a cool, dry place, away from direct sunlight and moisture. It is hygroscopic, meaning it can absorb moisture from the air, which may lead to caking. Storing it in sealed bags or well-ventilated silos is recommended to maintain its free-flowing granular form and extend its shelf life. Avoid mixing it with urea, as this can lead to ammonia volatilization and product degradation.

Q5: What are the environmental considerations when using DAP?

A5: When used responsibly and according to recommended application rates, Di ammonium Phosphate fertilizer contributes to sustainable agriculture. Over-application, however, can lead to nutrient runoff into waterways, contributing to eutrophication. Fizachem's low heavy metal content DAP further minimizes environmental impact. Best management practices, including soil testing and precision application, are crucial for environmental stewardship.

Q6: What is the difference between MAP (Monoammonium Phosphate) and DAP?

A6: Both MAP and DAP are excellent sources of phosphorus and nitrogen. The key difference lies in their N:P ratio and pH. MAP (11-52-0) contains more phosphorus relative to nitrogen and is slightly acidic (pH ~4.0-4.5). DAP (18-46-0) has a higher nitrogen content and is slightly alkaline (pH ~7.8-8.2). The choice between MAP and Di ammonium Phosphate DAP depends on soil pH, specific crop nutrient requirements, and application method.

Q7: Can DAP be used in foliar applications or fertigation?

A7: While Di ammonium Phosphate is highly soluble, it is primarily designed for soil application due to its relatively high salt index and potential for foliar burn if applied directly to leaves in high concentrations. For foliar feeding or fertigation, other highly soluble, less concentrated phosphorus sources (like monopotassium phosphate or specific liquid formulations) are often preferred to avoid plant damage and ensure efficient uptake. However, some very dilute solutions of DAP might be used in specific fertigation systems under expert guidance.
