WhatsappManufacturing process of Calcium Citrate
Calcium Citrate is manufactured through a carefully controlled neutralization and crystallization process to ensure high purity, consistent quality, and compliance with pharmaceutical and food-grade standards.
Step 1: Raw Material Selection
High-quality calcium sources and purified citric acid are selected and tested to ensure compliance with predefined quality specifications.
Step 2: Neutralization Reaction
Citric acid is gradually reacted with the calcium source under controlled temperature, pH, and agitation conditions to form Calcium Citrate.
Step 3: Purification
The reaction mixture is purified to remove any unreacted materials and process-related impurities, ensuring the desired product quality.
Step 4: Filtration
The purified slurry is filtered to separate the Calcium Citrate crystals from the liquid phase.
Step 5: Washing
The filtered crystals are thoroughly washed with purified water to remove residual impurities and soluble salts.
Step 6: Drying
The washed Calcium Citrate is dried under controlled temperature conditions to achieve the required moisture content without affecting product quality.
