Abstract: Un sistema de dosificacion de multiples productos (100) incluye una pluralidad de dosificadores de solucion de uso (10a, 10b, 10c), y un controlador (110) para seleccionar uno de los dosificadores (10a, 10b, 10c), de acuerdo con un régimen previamente establecido, por ejemplo, seleccionar diferentes dosificadores en diferentes días de la semana. Cada dosificador (10a, 10b, 10c) dosifica una concentracion controlada de solucion de uso utilizando un aparato de entrega de diluyente (13) que entrega un diluyente para formar un concentrado líquido a partir de una composicion química solida (22) y para formar diluyentes de relleno para diluir el concentrado líquido y formar una solucion de uso de una concentracion controlada. Un reductor de espuma (24) reduce la energía cinética del diluyente de relleno antes de mezclarlo con el concentrado líquido para reducir la espumacion. Un operador sin experiencia puede operar el sistema de dosificacion (100) para dosificar una solucion de uso de una concentracion cuidadosamente controlada, y el controlador (110) seleccionará automáticamente el dosificador apropiado de acuerdo con el régimen previamente establecido, sin una entrada adicional por parte del operador. Por consiguiente, se reduce mucho la posibilidad de que se presenten errores del operador mediante la seleccion automática del dosificador apropiado (10a, 10b, 10c) y el control sobre la concentracion de la solucion de uso.

Abstract: A multiple product dispensing system includes a plurality of use solution dispensers and a controller for selecting one of the dispensers according to a preset regimen, e.g., selecting different dispensers on different days of the week. Each dispenser dispenses a controlled concentration of use solution using a diluent delivery apparatus that delivers a diluent to form a liquid concentrate from a solid chemical composition, and to form make-up diluent for diluting the liquid concentrate and forming a use solution of controlled concentration. A foam reducer reduces the kinetic energy of the make-up diluent prior to mixing with the liquid concentrate to reduce foaming. An unskilled operator may operate the dispensing system to dispense a use solution of carefully controlled concentration, and the controller will automatically select the proper dispenser according to the preset regimen, without any additional input on the part of the operator. Therefore, the likelihood of operator error occurring is greatly reduced by the automatic selection of the proper dispenser and the control over use solution concentration.

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.
