BroucherManufacturing process of Potassium citrate
1. Raw Material Selection:
- Procure high-purity Citric Acid and Potassium Hydroxide / Potassium Carbonate as primary raw materials.
- Ensure all raw materials meet pharmaceutical (IP/BP/USP) or food-grade (FCC) quality standards.
2. Solution Preparation:
- Dissolve Citric Acid in purified water to prepare a citric acid solution.
- Separately, dissolve Potassium Hydroxide or Potassium Carbonate in purified water.
3. Reaction and Mixing:
- Gradually add the potassium solution to the citric acid solution under controlled conditions.
- Maintain stirring and temperature control to ensure complete reaction.
- Continuously monitor pH and concentration to achieve the desired Potassium Citrate solution.
4. Filtration:
- The reaction mixture is filtered to remove any undissolved impurities or solid particles.
- Use multi-stage filtration for high-purity product.
5. Concentration (Evaporation Process):
- The filtered solution is concentrated using evaporators to remove excess water.
- Control temperature and vacuum settings to prevent product degradation.
6. Crystallization:
- The concentrated solution is cooled gradually to induce crystallization of Potassium Citrate.
- Control cooling rate and agitation for uniform crystal formation.
7. Centrifugation & Drying:
- Crystals are separated using centrifugation or filtration.
- The wet product is dried in fluid bed dryers (FBD) or vacuum dryers to achieve the desired moisture content.
8. Milling & Sieving:
- The dried Potassium Citrate is milled and passed through a vibro sifter to obtain the required particle size distribution (PSD).
9. Quality Control & Testing:
- The final product undergoes rigorous quality control (QC) tests, including:
- Purity & Assay (IP/BP/USP/FCC standards)
- Moisture content
- pH and solubility
- Heavy metals & microbial limits
10. Packaging & Storage:
- The finished Potassium Citrate is packed in double-layer polybags inside HDPE drums or fiber drums.
- Labeled as per regulatory requirements and stored in a cool, dry place to maintain stability.
