Are you a stakeholder of a large powder filling operation, packing high value powder or free flowing products into pre-made sacks?
Of course, you don't need us to tell you that your packaging process is expensive and that your overhead costs are detracting from precious margin. You already know.
But how else are you supposed to accurately fill and safely seal up your bulk packages? Sure, the process is slow but you care more about quality than quantity and making sure that your large bulk powder or even pet food packages aren't overfilled- lest you give up even more margin.
Bulk powder packaging solutions have long been siloed into two categories- fully automated sacks from roll stock with poor accuracy, poor seal integrity and poor package sturdiness OR partially automated, with folks either hand filling or loading empty sacks onto a premade sack filling machine to fill.
The older automated sack filling machines are suitable for many lower-value products(like soils), but while consumers might tolerate a little bit of mulch in the bed of their truck, they certainly don't (and shouldn't!) feel that way about their dog's food or a sack of concrete.
Fully automated, highly accurate pouch forming, filling and sealing machine capabilities historically only extended to pouches up to a couple pounds, but Rovema has extended their reliable vffs solutions to include capabilities for bulk filling and bagging so that producers can reap the same benefits of exclusive Rovema technologies as folks in the retail coffee or snack spaces.
By equipping the SD-H auger filler with the standard horizontal feed screw to maintain consistent head pressure, many are able to get extremely high filling accuracy. But for extremely high-value powder products that need the highest accuracy possible, the auger can be equipped with weigh cells that trickle in the last ~5% of the product.
Dust kicked up by the packaging process of bulk dry powders is inconvenient, wasteful and a pain. However, for some products, it can also be dangerous for the folks working in your facility and thus they must wear protective and expensive gear to keep them safe from the airborne particles.
By incorporating a Rovema SD-H auger filler with vacuum dosing into your bulk packaging line, you can eliminate these issues. At the end of each dosing process, the vacuum lock prevents tiny particles from tickling down, causing it to be kicked up.
Like it's mentioned above, there are plenty of "good enough" bag fillers and other solutions for lesser value bulk products, that from a total cost of ownership perspective, make more sense for products that fit the profile.
But if you're looking to automate your bulk packaging process for high value products, without compromising on filling accuracy, package strength or seal integrity, you'll have heavier factors to weigh, like cost of product give-away, cost of product spoilage, or even your relationships with your customers.
Globally, these are the spaces we're seeing the biggest impact:
For your high value, oxygen sensitive products, being able to maximize your products' shelf life by efficiently achieving less than 1% residual oxygen results in better value for your customers and retailers.
Heavy sacks of product need uncompromising seal strength, or else you risk losing a tremendous amount of product. Thanks to the patented Rovema Premium Seal® technology, our seals are considered the strongest in the industry, withstanding fork truck drop tests as demonstrated in the video about Aromaperm.
For your bulk packaging operation, every package that's formed, filled and sealed holds a substantially higher amount of liability than many folks packaging retail stand up pouches, for example. If you have a bad seal from a piece of kibble getting caught during the sealing process, you often don't lose just one 40lb sack of food- you lose both.
Sense and seal allows your machine to detect this, prevent it from happening and keeps the product clean, so that it can be added back in upstream to prevent waste.
