WhatsappManufacturing process of Potassium bicarbonate
Step 1: Raw Material Selection
- High-purity potassium carbonate and carbon dioxide are used.
- Raw materials undergo strict quality checks for purity.
Step 2: Chemical Reaction & Processing
- Potassium carbonate reacts with carbon dioxide to form Potassium Bicarbonate.
- The solution is filtered and purified to remove impurities.
Step 3: Crystallization & Drying
- The solution is crystallized, dried, and milled to achieve the required purity.
Step 4: Quality Control & Testing
- The product is tested for assay, solubility, moisture content, and pH as per IP/BP/USP standards.
Step 5: Packaging & Storage
- Packed in HDPE bags or fiber drums to prevent contamination.
- Stored in a cool, dry place to maintain stability.
