A Cape Town oat and granola producer needed to fill oat flour and granola into pre-made pouches. We supplied a semi-automatic auger filler with a band sealer for oat flour, a four-head weigher fed by a Z-type elevator for granola, and an automatic linear fill-seal line for 500 g to 1 kg zipper pouches.
The customer packs oat flour and instant oats in 1 kg stand-up zipper pouches, and granola in 500 g zipper pouches. The two products need different dosing. Oat flour is a fine powder, so it is dosed by an auger. Granola cannot go through an auger, because the turning screw would crush it, so it is weighed instead.
The customer wanted to fill both products into pre-made pouches with an operator, and on an automatic line for higher volumes.
Fill oat flour by auger into 1 kg pouches, with an operator placing and sealing each pouch.
Weigh granola into 500 g zipper pouches without crushing it.
Open, fill, flush and seal pre-made zipper pouches automatically, for powder or granola, from 500 g to 1 kg.
We supplied the pouch filling in two stages. For lower volumes, a semi-automatic auger filler with a band sealer fills oat flour, and a four-head weigher fed by a Z-type elevator weighs granola into pre-made pouches for an operator to seal. For volume, an automatic linear fill-seal machine for pre-made bags opens, fills, gas-flushes and seals zipper pouches, with a 10-head weigher for granola and an auger filler for oat flour. Product-contact parts are stainless steel.
The linear machine takes each pre-made zipper pouch from a magazine, opens it, fills it from the weigher or the auger, flushes it with gas and seals it.
| Oat flour, semi-automatic | Auger filler with band sealer; rated 15 to 25 pouches a minute; auger screws for 10 g to 5 kg |
| Granola, semi-automatic | Four-head weigher, 50 to 500 g, rated 30 to 40 bags a minute, ±2% |
| Product feed | Z-type elevator, 7,200 L an hour; screw conveyor for oat flour |
| Automatic line | Linear fill-seal machine for pre-made bags, 500 g to 1 kg |
| Pouches | Zipper or three-side seal, 90 to 240 mm wide, 110 to 350 mm long |
| Dosing on the automatic line | 10-head weigher for granola; auger filler for oat flour, ±2% |
| Automatic speed | 35 to 40 pouches a minute, depending on product and fill |
| Extras | Gas flushing, zipper opening, stainless steel working platform |
| Power | 380 V, 3.2 kW (linear machine); 220 V, 2 kW (four-head weigher) |
Each pre-made pouch goes from the magazine to a sealed, gas-flushed pack in one pass.
A Z-type elevator lifts granola to the 10-head weigher, and a screw conveyor feeds oat flour to the auger.
The machine takes a pre-made pouch from the magazine, opens the zipper and opens the pouch.
The weigher or the auger fills the pouch with 500 g to 1 kg.
Gas is flushed into the pouch before it is sealed.
The top is heat-sealed and the finished pouch is discharged from the machine.
The semi-automatic filler and the four-head weigher let the customer pack both products with an operator at each machine. The automatic line fills the same pouches at a rated 35 to 40 a minute, running powder and granola through one machine. These are the machines’ rated speeds; the output the customer achieves has not been measured for this case study.
