Abstract
A solid product dispenser can be used to form a dilute liquid solution from a block of solid concentrate. In cases where only a small amount of liquid solution is needed, the solid product dispenser may dissolve the block of solid concentrate quickly and substantially uniformly to provide a solution of controlled concentration. This can be contrast with larger dispensing applications where a dispenser may dissolve a block of concentrate slowly at the start and more rapidly as the dispensing progresses, producing a solution with an average concentration higher than if only a small amount of solution were produced using the dispenser. In one example, the solid product dispenser includes a fluid distribution reservoir and a solid product reservoir positioned inside of the fluid distribution reservoir and over a platform on which the solid product sits. High pressure fluid flows between the two reservoirs, turbulently contacting the solid product.
