The Stir Paddle Kit can be an effective tool for larger particles that tend to bridge. A quick twist and chop of the handle breaks up any product that has bridged, allowing the product to flow freely again.
Keep in mind, toppings that melt in an ambient serving environment will do so in the dispenser as well. That means crushed candy bars are not a good fit.
Stir Paddle Kit (86596) is designed specifically for Server Products Dry Product Dispensers with a 2-Liter capacity. Please take note of the slight change in the dispenser lid shape; when combining dispensers with and without a Free Flow Kit.
