Filling and weighing
The bagger sets the speed of your line and how much product you give away in every bag. We represent Hamer, JEM and TMI, and offer an imported line for tight budgets. We help you choose based on your product, your bag and your output.
How to choose
Up to about 8 bags per minute, a gross-weight bagger is the most efficient option. Above that rate we recommend net weight: since the scale prepares the next weighment while the bag is being filled, the line does not wait for weighing and gains speed and accuracy.
Brands we represent
Equipment from the United States and Spain with spare parts, installation and service in Costa Rica.
* Maximum reference capacities. They depend on the product being filled and on the operator's skill.
Economy line
For plants moving from manual filling to filling by weight with a smaller investment.
Line project
Example of a line designed for a customer in the region: surge hopper, gross-weight scale, conveyor and bag closer integrated into a single system.
| Line data | Reference value |
|---|---|
| Total footprint | 2,73 × 1,42 m |
| Total height with hopper | 3,10 m |
| Fill spout height | 1.22 m above the floor |
| Scale | 110 V, single phase · air 3 cfm at 80 psi |
| Bag closer and conveyor | 230/460 V, three phase · air 2 cfm at 40 psi |
Reference layout from a previous project. Dimensions and consumption are confirmed in each project's design.

| Hamer 100GW | Gross, digital | up to 8 | ±28 g | 5–50 kg | USA |
| JEM Digital Royal | Gross, digital | up to 7 | ±50 a ±100 g | 5–50 kg | USA |
| JEM Digital Wolverine | Gross, digital | up to 7 | ±100 g | 7–50 kg | USA |
| TMI ILERFIL-ABG | Gross, gravity | 6 a 8 | Class 0.2 (MID) | Depends on the bag | Spain |
| Hamer 100GWB | Gross, belt | up to 8 | — | 5–50 kg | USA |
| Hamer 600NW+ | Net, digital | 15 a 20 | up to ±14 g | 5–50 kg | USA |
| NH series | Gross, belt | up to 4 | Graduation 20–100 g | Depends on the bag | China |
| Duplex net weight | Net, gravity | up to 8 | < ±0,2 % | 20–50 kg | China |
Reference capacities: actual speed depends on the product being filled (flowability, density), the bag type and the operator's skill.
To guarantee the declared weight, an inaccurate scale forces you to overfill. At 2,000 bags a day, every 50 g of overfill adds up to 100 kg of product given away each day. A more accurate scale pays for itself.
One with stainless steel product-contact parts: Hamer 100GW in 304 stainless, JEM Royal or Wolverine with stainless contact parts, TMI ILERFIL-ABG or, in the economy line, 316L stainless contact parts.
For sticky, damp or irregular-sized products, belt feed (Hamer 100GWB, TMI ILERFIL-ABT or the NH series) or auger feed for powders is the better choice.
Yes. We design the complete line: hopper, bagger, conveyor and sewing or sealing system working at the same pace.
