Abstract: Disclosed is a dispenser 10 for a solid chemical 13 and a method of dispensing the chemical 13. Water enters via an inlet line 22 and is sprayed from a spray nozzle 21, so that the solid chemical 13 is dispensed in the form of an aqueous chemical solution via outlet line 17. The solution's concentration is adjustable by varying the distance between the spray nozzle 21 and the exposed dissolving surface of the chemical 13. The spray nozzle's position is adjusted by means of a screw jack 68, a push-pull cable 93, a solenoid 100, or a lever 117.

Abstract: An apparatus and method for programming a detergent controller to vary the detergent concentration set-point according to the time of day and to achieve detergent concentration levels quickly without incurring overshoot. Thus, the present invention insures that the warewashing machine is operated at optimum efficiency and cost. To vary the set-point according to the time of day, the invention combines the features of a microprocessor, a clock and a controller into one unit. The user enters the time setting and set point into the controller. The microprocessor then compares the real-time clock signal with the user time settings and outputs an appropriate set-point value from the microprocessor to the controller. To achieve detergent concentration levels quickly without incurring overshoot, the controller senses the detergent concentration and dispenses the proper detergent level to the warewashing machine according to a predetermined detergent feed time based on the previous response time and the programmed set-point. Thus, the controller can change the response function if and when conditions change.

Abstract: A dispenser (10) uses first and second flow controls (70, 73). The flow controls maintain first and second flow ranges independent of diluent pressure within a pressure range, wherein the use solution's concentration is maintained over the pressure range. A third flow control (75) may also be utilized in a third diluent passageway for maintaining a third flow range independent of the diluent pressure within the pressure range. A bypass valve assembly (41) is operatively connected to the third incoming diluent passageway. The bypass valve has a temperature control valve. The temperature control valve having a bypass passageway, wherein additional diluent is added to the use solution, thereby controlling the use solution's concentration.
