Pump tops and automatic dosers that measure syrup to the millilitre. In bubble tea the sugar level is what the customer orders — «50%», «no sugar» — so a shop that doses by eye is failing the one thing it was asked to get right.
It doses liquid fructose or sugar syrup by volume at the press of a button, so every drink gets the same sweetness without free-pouring.
A pump top is cheap and fine at low volume; an automatic syrup dispenser is faster and repeatable, which starts to matter once a bubble tea bar is busy.
Dual-tank models run two syrups, or a syrup and fructose side by side. Tell us how many flavors you pour and we'll size it.
A sugar syrup dispenser on the bar holds simple syrup at a measured pump; a flavor syrup dispenser rack does the same for a coffee counter. A bubble tea syrup dispenser is built for thicker fructose and is worth specifying separately.
