Vibrator for the pharmaceutical industry PM VIB

We recommend a vibration time of 30-60 seconds for most powders. Longer vibration times do not result in higher fill weights for most powders other than fluid-like powders. While vibrating we recommend spreading the powder across the capsule bodies to reduce fill weight variation. Remember to spread powder to all four edges of the filling surface. For many powders (including fluid-like, fine and fluffy powders) you can achieve a higher fill weight with a combination of vibration, spreading and tamping. Vibrate and spread the powder for 30-60 seconds. Use a Tamper to press powder gently into the capsule bodies without forcing powder out of the capsule bodies. Repeat vibration and spreading followed by tamping. After the final tamping, spread any remaining powder across the capsule bodies. For maximum fill weights, you can do up to 4 vibration/spreading and tamping cycles. In general, we do not recommend more than 2-3 cycles as we have found that with all powders we have tested, the fill weight does not increase by more than 1-2% after 3 cycles. Due to wide variations in properties between powders, their grades and suppliers, your results will vary. BENEFITS OF POWDER VIBRATION • Reduced Filling Time - 60 seconds or more per cycle • Increased Fill Weight • Reduced Fill Weight Variation You may see some or all of the above benefits depending on the properties of the powder filled. A Vibrator is also helpful when filling 2 or more tablets inside capsules. Tablets can fall and sit vertically inside the capsule body, leaving insufficient room for more tablets Bridging Some powders form a bridge at the top of the capsule body, leaving air pockets inside the capsule body.
