A method of warewashing for the removal of starch is described herein. The method includes applying an alkaline composition to a dish, then applying an acidic composition to a dish, and then applying a second alkaline composition to the dish. The method may include additional steps. Compositions for using with the method are also disclosed. Finally, dish machines that may be used in accordance with the method are disclosed.

Methods and compositions for the removal of starch

A preferred embodiment method for dispensing a use solution from a solid product into a dishwashing machine includes placing a solid product in a dispenser. The product dispenser () for dispensing a use solution from a solid product includes a chamber () having a front (), a back (), and a bottom (). The chamber () defines a cavity () configured and arranged to receive a solid product and a diluent. An inlet () proximate the back () of the chamber () is configured and arranged to receive the diluent, and an outlet portion () is in fluid communication with the inlet (). The outlet portion () spans a length of the back () and includes a plurality of apertures () along the length of the back (). The plurality of apertures () allows diluent to fan out along the back (), flow down the back (), and cascade evenly with relatively even pressure from proximate the back () toward proximate the front () of the chamber (). A use solution outlet () proximate the bottom () and the front () of the chamber () allows diluent and a use solution to exit the chamber ().

Method of using a solid rinse additive dispenser for dispensing a use solution in a dishwashing machine

The alarm mechanism of the invention signals the absence of a liquid from a source of aqueous liquid. The alarm mechanism comprises an alarm body having an inlet port and an outlet port; the inlet port in liquid communication with a source of liquid, the outlet port in liquid communication with a use locus. The alarm mechanism additionally comprises a float chamber placed in liquid parallel communication with the inlet port and the outlet port. The float chamber contains a float operably connected to a mechanical alarm. The float, as the chamber is emptied of liquid, reaches a position wherein a 'low or empty product' signal is generated. The apparatus operates by passing liquid through the body. As liquid in the source of liquid is depleted and is no longer available for passage through the body, the body becomes emptied of liquid as the source of pressure removes liquid from the body and particularly from the chamber causing the float to reach a position generating a signal.

Empty product detector

A dispensing apparatus 10 includes a container 11 and docking station 20. A needle 35 positioned in a probe 40 which is located on a movable member 45 is guided into a container insert 60 which is positioned in the outlet 12 of the container 11.

The alarm mechanism of the invention signals the absence of a liquid from a source of aqueous liquid. The alarm mechanism comprises an alarm body having an inlet port and an outlet port; the inlet port in liquid communication with a source of liquid, the outlet port in liquid communication with a use locus. The alarm mechanism additionally comprises a float chamber placed in liquid parallel communication with the inlet port and the outlet port. The float chamber containing a float operably connected to an alarm. The float, when a chamber is filled with fluid, disables the switch from generating a signal. The float, as the chamber is emptied of liquid, reaches a position and is detected energizing the switch to send a 'low or empty product' signal. The apparatus operates by passing liquid through the body. As liquid in the source of liquid is depleted and is no longer available for passage through the body, the body becomes emptied of liquid as the source of pressure removes liquid from the body and particularly from the chamber causing the float to reach a position generating a signal.
