Hello everyone,
I have a project for bottle filling machine for low to medium viscosity liquids. I understand the products vary slightly some having more granular material to it than other, either sugar or salt.
I've done my research and I understand the two most common are overflow nozzles which provide consistent level and not very time critical, and the other is straight open nozzle which requires precise timing to maintain consistency.
Control is not a concern but I have zero experience with bottle filling and the customer's main concerns have to do with fill level and drip. Their old machine has overflow nozzles that seems to always drip and leaks and for some reason the removed the drip tray.
Is drip unavoidable and is just something that has to managed or is some way to eliminate that? I though of a small air nozzle to blow that liquid off the nozzle but that will make more mess than anything else. What else is out there.
Edit: Wacky thought, how about overflow nozzle with some slow return mechanism that the overflow tube is still exposed as the nozzle is raised, and as it begins to raise something sucks air through the overflow nozzle hopefully sucking then a time nozzle/hose shoots a small burst of air on the the tip of the overflow nozzle so that the drip falls in the bottle itself. Would that work? I would definitely slow down the process but the gain in eliminating dip on the the outside of the bottles far exceeds the extra time taking for this process; assuming it is doable.
