    6.The Essential Properties of Powders you should know Before Packaging?

    Essential Properties

    There are various factors you need to consider to ensure the success of the packaging process because the effectiveness of the packaging line not only depends on powder filling equipment but also on how much knowledge you have on the factors associated with the packaging of powder.

    Properties of Powder That You Should Consider

    The Flow Characteristics of Your Product

    Flow Characteristics of Your Product

    The consistency and ability to flow will determine the type of filling system necessary to ensure an effective and accurate packaging line. Products could be free-flowing or non free flowing. Free-flowing products like granulated sugar and salt particles are not cohesive, fall with gravity and while adding a little pressure it will not compress and will not maintain their shape even if their particles are manipulated.

    Non-free-flowing products like powdered milk and brown sugar are cohesive. They usually keep their shape when you manipulate their particles. You can also compact them under pressure. Packaging is carefully handled as particles tend to stick together.

    The Bulk Density of Your Product

    Bulk Density of Your Product

    A powder’s bulk density describes its flowability and how much it will compact when you apply pressure to it. The more particles are compacted, the higher their bulk density will be. It will directly impact pouch size and design to determine the filler equipment and processing speed essential for efficient production.

    The Dustiness of Your Product

    Dustiness of Your Product

    There are some powder products that form dust clouds when dispensed like flour when it comes to the packaging machine, it might encounter serious mechanical problems due to the loose dust particulates which can travel and cling to any surface. The jaw drive of the machine should be enclosed to protect its moving parts. Ensure that your machine is equipped with a dust hood.

    7.Why Does Bulk Density Matter in Powder Packaging?

    Bulk Density Matter

    Bulk density measures the flowability of your powder particles and their compressibility when pressure is applied. Bulk density directly affects the characteristics and measurement of packaging material you’d require depending upon how compact the powder is.
    Let’s suppose you take crushed coffee beans powder at one place and whole coffee beans at other, even though both will be weighing the same mass but it will differ in the volume they both will respectively occupy once you have done packaging them.
    Usually non free flowing powders are bulkier in density as they can be compressed due to their cohesiveness unlike free flowing granules which have much empty spaces between them and are not cohesive.

    8.Powder Packaging: How is Powder Packaging Done?

    Powder packaging is a complicated process requiring utmost accuracy and precision. The main steps in powder packaging are:

    Loading of Premade Pouches or Film roll

    Loading of Premade Pouches or Film roll

    Preformed pouches or film roll is placed on the bag magazine or unwinding device respectively. Premade pouches are picked by robotic gripper arms or bags feed conveyors and are carried to interior of the equipment for inflation and filling.

    Pouch Formation

    Pouch Formation

    Film for forming pouches travels across rollers to forming collar where it is shaped into required pouch shape.

    Filling

    Filling

    Next step is filling which is done by auger or vibratory fillers. Auger fillers are suitable for loading free-flowing powders. In auger fillers, filling is carried out by the coordinated action of auger screw and sensors.

    The filling process is initiated by the signal from sensor which in turn starts turning of auger screws. This loads the powders in pouch or container. After filling desired amount of powders in containers, the sensors then signals to stop filling powders. For hard to flow powders, vibration or impact is used to facilitate the powder flow.

    Sealing

    Sealing

    After filling, top layers are sealed and glued by sealing elements using heat. These pouches are then moved to cartoning or palletizing machine.

    This results in accumulation of debris at inner sides of tubes or bridging of powders in hoppers or fillers which stop their particles from filling the packaging containers.

    This predicament is solved by furnishing your machines with clean-in-place systems that thoroughly clean your systems without requiring much effort on your part.

    Contamination and Damage

    Contamination and Damage

    When transferring powder materials from one area to another, there is the risk of contamination and damage to the products. Various kinds of conveyors such as vibratory, flexible, or pneumatic are used for avoiding the product damage and degradation.

    These conveying systems use compressed air, auger, disks, or vibratory motion for safe movement of powders.

    Dust Generation

    Dust Generation

    Packaging powders more than often leads dust generation. When packaging dry, milled, granulated or dusty products much dust is produced since the particles of these products have tendency to become airborne when packaging machine starts or stops.

    This issue can cause health related problems in working personnel such as respiratory troubles due to inhalation of dust.

    To prevent this dilemma, powder packaging machines are equipped with dust proof enclosures, vacuum suction systems, dust hoods, and vacuum locking systems.

    Electric Explosions

    Electric Explosions

    Airborne dust is prone to trigger electric sparks which are often caused by the buildup of electrons. Mixture of gases used while packaging and electric sparks can be a deadly combination usually resulting in explosion.

    If you use static elimination bars and vacuum pull belts in your packaging systems then you will be prevent electric hazards.
