Coffee Packaging Machine: Model S4 – Gross Weight Bagging Scale

bagging coffee with the logical machines s4The Model S4 is an affordable, well-built, entry-level coffee packaging machine.  It is the perfect cure for business owners and coffee roasters that are tired of manually scooping and weighing coffee into bags and pouches ranging in weight from a couple of ounces up to 10 pounds.  The company that builds the S4 has a proven track record and has been manufacturing American made, high quality bulk weighing and packaging machines since 1994.

This machine has one of the simplest set-ups.  With a press of a button, you can quickly change the different bag weight / fill sizes.  It is perfect for packaging whole coffee beans or coffee grounds.  It can also bag many types of teas, snack foods, candy, nuts, spices, powders, and other free-flowing dry bulk products.

How do you package coffee with the S4?

The steps outlined below are for filling a 16 oz (1 lb) bag with roasted whole coffee beans.

1. Coffee beans are loaded into the supply hopper at the top of the S4 and the target fill weight is set to 1 lb on the controller.

2. The operator places a 1 lb bag on the fill spout.

3. The first fill cycle is started by depressing the foot pedal. At this point, the machine and controller switches into “learn mode” for the first cycle.  The controller tests the flow characteristics of the coffee beans and decides the best speeds and duration for the vibration of the feeder.

4. The controller will start a bulk flow (fast flow) of the coffee beans from the hopper, through the vibrating feeder, and into the weigh hopper below. Once the target set weight of 1 lb nears completion, the controller will automatically switch to a dribble flow (slow flow) of the coffee beans into the weigh hopper.  Once the set target weight of 1 lb has been reached, the feeder stops.

5. The weigh hopper releases the 1 lb of coffee beans into the bag that is placed on the spout.

6. Each bag after the first fill cycle is now filled automatically with the perfect amount of coffee beans by placing it under the spout and depressing the foot pedal.

7. After filling each bag, the operator sends it through a vacuum bag sealer or band sealer to lock in freshness with a flush of nitrogen, print date codes, trim bag tops, and more.
