The Logical Controller II

The Logical Controller II

Our exclusive SMART Mode makes filling coffee easy!

Smart Mode allows the Logical Controller II to learn how your coffee flows and automatically adjust its parameters on-the-fly to maximize accuracy and speed. In a matter of minutes, your Coffee Filler will be filling bags with no need for you to adjust, tweak, or fiddle with a single control setting.

Setting up your Coffee Filler is a snap: once you've unpacked and prepared your Coffee Filler according to the provided instructions, just follow these 3 simple steps to start filling coffee:

1) Turn on the Logical Controller II (The switch is on the bottom of the Controller.)

2) Fill the Supply Hopper at least half-full with your coffee. (Don’t forget to put one of your containers under the spout!)

3) Press the footswitch to start filling your coffee.

That's it! The Controller will continue to refine its accuracy and speed on-the-fly as it fills.

Prescott Coffee

"I have a small wholesale coffee roasting business where I sell 450-550 pounds of roasted coffee each week. Since the roaster I use doesn’t have automation, I needed to make the rest of my process more efficient. The S-4 Semi-Automated Scale System was a great fit to my destoner / loader.

"I hadn’t realized how much of a distraction filling bags had been until I had the new system up and running. Being able to switch between three bag sizes at the push of a button has been a real bonus. The S-4 can handle many more bag sizes if I need something beyond 1, 2, or 5# pounds. By the time I finish sealing and placing the bag on a shelf the next 5 pound bag is just finishing being filled.

"The surfaces of the machine are easy to keep clean. There is no other real maintenance needed. I can check the calibration of the weigh system easy enough and re-calibrate it if necessary, but so far it is solid. This is one of those purchases I could have done years ago and benefitted greatly."
