Nutritional powders are generally high in value and vary in characteristics. Some are prone to moisture absorption and caking, while others tend to generate dust. To address these specific challenges, DJ-Pack (Dingjiang) offers systematic solutions based on 20 years of experience in the powder packaging industry.
Moisture Absorption and Caking of Powders
Most vitamin and mineral powders are highly hygroscopic. When exposed to air, they easily absorb moisture, leading to caking, reduced flowability, uneven discharge, and poor filling accuracy.
DJ-Pack's Solution
Integrate a dry air environment in key areas of the equipment to physically isolate humid air. Utilize a sealed hopper to minimize the duration and area of contact between the powder and air. Apply food-grade Teflon coating and mirror polishing to the auger and inner walls in contact with the powder, reducing adhesion and retention of moisture-affected powder.
Demixing (Segregation) of Powder Materials
Compound nutritional powders, being mixtures of different densities and particle sizes, are prone to density segregation during conveying and vibration, resulting in uneven powder composition and affecting product efficacy.
DJ-Pack's Solution
The hopper is equipped with an agitation function to maintain uniformity of the powder material. Auger conveying is employed to ensure the powder material enters the metering system evenly and stably.
Filling Accuracy Issues
Due to the high cost of such powder products, both overfilling and underfilling can lead to significant impacts, making precision requirements particularly stringent.
DJ-Pack's Solution
Utilize a servo motor to drive the twin augers, allowing for precise control of the delivery amount. An integrated weighing module monitors the weight in real-time, ensuring filling accuracy.
The filling and packaging of nutritional powders require suppliers to have a deep understanding of material characteristics in order to provide reasonable solutions. With 20 years of experience in powder packaging, DJ-Pack (Dingjiang) offers reliable service and guarantees for your nutritional and health products.
