 Automatic Weighing and Filling machine

The Model UN-S4 Automatic Weighing and Filling machine is a great first step to take your business from hand scooping to automation.  Your bulk product is placed in the supply hopper at the top of the machine. It uses an electromagnetic vibratory feeder to move the product from the supply hopper to the weigh hopper where it is weighed.  When the target weight is reached, the Controller stops the feeder, and the weigh hopper opens automatically or with the foot switch to dump your product into your container.  After that a new fill cycle is started and your filled bag may now be sealed.​​

Here are some of the features it offers:


• Self-adjusting Controller
• Reads out to 1 gram or .001 lb
• Controller range up to 10lbs.
• Supply Hopper capacity 3.5 cu.ft. (equivalent to 5 five-gallon pails).
