We have seen various opinions for packing powder in flexible packaging material, which is known as VFFS machines. But there are various other machines to pack powder products.
Powders are basically of 2 types, mainly free flow and non free flow properties. When you’re planning to buy powder filling equipment for your project, first try to understand bulk density and properties of your product. Your package, fill quantity, production per day is equally important before buying a powder packing machine. Spend a while comparing the overall performance of every filling system to find which one fits best for your application. In this blog article, we present to you the common types of powder filling equipment utilized in diverse industries.
#1 Capsule Filling Machine
These are normally used for filling pharmaceutical products and can only carry out small powder fill quantities at once but with multiple cavities. They are dedicated fillers and do not have scalable alternatives too; so they’re among the less utilized fillers or dedicated for capsule filling application only.#2 Screw Based Powder Filling Machines
Commonly known as Auger Filler. It’s designed on the screw’s positive displacement principle. It includes a hopper, auger screw, barrel and stirring bar and its most popularly utilized volumetric powder fillers. These are best-suited in filling fine powders at extraordinarily rapid speeds. They do not emit a lot of dirt however they may be equipped with dust collectors anything you prefer. Lastly, with uniform particles auger powder filling machines can each fill powder products, non-free flowing and free-flowing. Easy changeover for various fill weights is also possible with a set of change parts. We can fill micro quantities to bulk bags by using this filing system.#3 Vacuum Powder Filling Machines
Vacuum powder fillers can fill powder products into diverse containers without an auger and agitator. Meaning, the powders do not go through any breakdown or agglomeration which preserves the product’s integrity. They produce little to no dirt and can deal with all free-flowing and non-free flowing powders with rapid changeover of fills. This type of filling system is usually used for bulk transfers or bulk bag fillers. However, vacuum fillers cannot deal with irregularly shaped/sized products and regular maintenance of the vacuum system plays key role in this filing system.#4 Volumetric Cup Powder Filling Machines
Volumetric cup means cylinder, and fill weight is calculated by formulae of cylinder volume and bulk density of powder. These filling machines however do not work properly with non-free flowing powders are perfect for managing free-flowing powder products. They can fill up to 100 containers per minute and are quite inexpensive than other filling equipment’s. You must remember that everytime powder BD and fill weight will change a set of cups required as a change part. There is no positive push applied on powder so once dispensed travel of powder depends on gravitational force only.#5 Net Weight Powder Filling Machines
Net weight filling machine is the only filling system that actually weighs product prior to dispensing into the final container. Net weight fillers can be applied for a big range of products including dry or barely moist products, free flow or non free flow powders and for filling a big range of regular and irregular sized products. Net weight filling systems also can be set up in numerous formats for gentle handling of products like vibratory feeder, screw feeder, vacuum transfer etc. Load Cell based electronic weighing scale is used to weigh the product before dispensing in the container. Examples- cement, chemical powders, wheat flour are filled using net weight fillers. Having sufficient information concerning the different sorts of powder filling machines assist you to decide which machine will work best for your application. Machines are large investments so you want to ensure that you get the proper one to avoid any incompatibility problems in the long run.
