Mass-Based Powder Dispensing
First Claim
Patent Images
1. A system comprising:
- a dispenser that dispenses a powder product containing an active ingredient from a product container;
a weigh assembly that continuously determines, as the powder product is dispensed, a current weight of the product container; and
a controller that determines when a transition criteria has been satisfied based on the current weight and determines when a requested amount of the powder product has been dispensed based on the current weight of the product container,wherein the dispenser dispenses at a first, higher dispense rate until the transition criteria has been satisfied and then dispenses at a second, lower dispense rate until a requested amount of the powder product has been dispensed.

Abstract
Mass-based dispensing of a powder product includes a system that dispenses a powder product containing an active ingredient from a product container. The system initiates a dispense cycle at a first, higher dispense rate. The system continuously determines, as the powder product is dispensed, the amount or weight of the powder product that has been dispensed. Once a transition criteria has been satisfied, the system adjusts the dispense rate to a second, lower dispense rate. The system dispenses the powder product at the second, lower dispense rate until a requested amount of the powder product has been dispensed.

22. A method, comprising:
-
dispensing a powder product containing an active ingredient from a product container at a first, higher dispense rate; continuously determining, as the powder product is dispensed, a current weight differential of the product container corresponding to a current dispensed amount of powder product; determining when a transition criteria has been satisfied based on the current weight differential; adjusting the dispense rate to a second, lower dispense rate when the transition criteria has been satisfied; determining when a requested amount of the powder product has been dispensed from the product container based on the current weight differential; and discontinuing the dispensing of the powder product when the requested amount of the powder product has been dispensed. - View Dependent Claims (23, 24, 25, 26)
