Applications of Vibro Sifter in the Pharmaceutical Industry
- Particle Size Separation: Provides uniform granule size distribution in tablet compression and capsule filling.
- Removal of Oversized & Undersized Particles: Removes large lumps, foreign particles, and fines to enhance the quality of the product.
- Screening of Wet & Dry Granules: Utilized following granulation and drying to provide uniform particle size prior to compression.
- De-Dusting of Tablets & Capsules: Resolves excess powder from capsules and tablets prior to packaging.
- Pre-Screening of Raw Materials: Guarantees raw powders employed in formulations are devoid of impurities.
Applications of Vibro Sifter in the Food Industry
- Flour & Powder Screening: Eliminates impurities from wheat flour, rice flour, and baking powders.
- Sugar & Salt Grading: Guarantees even particle size of crystal sugar, icing sugar, and salt.
- Spice & Ingredient Screening: Eliminates lumps and ensures uniformity in spices, seasoning powders, and mixed food ingredients.
- Dairy Powder Processing: Applied in sieving milk powder, whey powder, and protein supplements to sift out clumps.
- Tea & Coffee Processing: Applied in grading tea leaves and coffee granules to get even size.
- Juice & Liquid Filtration: Used to sift out unwanted solid particles from fruit juice, syrup, and edible oil.
