Each product (large or small) should be filled adequately, then sealed and wrapped for its delivery into the market. Ever since, there has been constant research that has enabled engineers today to design machinery that suits the packaging of different products. Filling machines, for instances, are known as fillers and are used for filling powders, liquids, and granules in drums, vials, bottles, pouches, and other suitable containers.
Every machinery from powder filling machine manufacturers is designed for the packaging of free-flowing granulated and powdered products. There are different types, although the term is generic rather than a limitation to what applications the machine can run. Here are your options:
Net Weight Fillers
This is the only powder filler that will weigh your product before it is dispensed into a container. This negates the need for installing a checkweigher along your packaging line.
Net weight fillers move products along a packaging line from hoppers via vibratory belts or trays into a bucket, which is loaded onto a cell. They are highly accurate, have a gentle product handling capability, can handle irregular product weights, sizes, and shapes, and can be adapted for the packing of consistent piece count products.
These are, unfortunately, slower compared to other filler options. Moreover, the packaging of very fine powders like powdered milk, flour, and talc can get messy.
Auger Filling Machines
These are volumetric machines designed for the packing of very fine powders and all products that have consistently sized particulates. They comprise of a main hopper, which stirs the powders into a closely fit cylinder. Though auger filling machines will not weigh the products, they remain accurate if the products are fed consistently. They’re faster compared to net weight fillers, are relatively dust-free, are easy to integrate, and are cost-effective.
It is, however, not that accurate for goods with irregular densities and shapes. It might damage products that cannot hold up to compression.
Cup Filling Machines
Also known as pocket fillers and volumetric machines, they are intended for free-flowing products like granules, coarse powders, and nuts. They comprise of a hopper on top of a cup that feeds products into it using gravity. There are also wipers to get rid of the excess products so your cup remains on its proper level. The cup is moved to the end of the discharge chute where its contents are put in a bag.
Although simple to use and maintain, fast, and inexpensive, cup filling machines do not package products with irregular shapes or densities.
Pail Filling Machines
These are used for packing large volume products. Most can handle weights of up to five tons. They are an economical and accurate alternative to the filling of small pails with your product, then pouring it into larger pails.
The above machines will undoubtedly make a significant difference to your entire production line. Your choice of filler, which suffices for your product, is based on your product’s characteristics, such as size, shape, stickiness, and viscosity. The speed of packaging you’re aiming for and the size of the packages you’re filling will also determine the best machine for your company.
