Solid product dispenser and method and apparatus to control dispensing rate of a solid product with changing temperature

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.

Description

Solid product compounder and method and apparatus for controlling solid product compounding rate by changing temperature technical field This invention relates generally to the formulation of solid products with diluents, and more particularly to methods and apparatus for controlling the rate of formulation as the diluent changes temperature. Background technique Dispensers that utilize diluents to attack products such as sanitizers or detergents are well known. The formulated product is usually a solid product and can take the form of chemical solid blocks, pellets or castings. An example of such a dispenser appears in U.S. Patent 4,826,661 to Copeland et al. This patent discloses a solid block chemical dispenser for cleaning systems. The dispenser includes a nozzle for directing a uniform spray of dissolving liquid onto the surface of a solid block of cleaning composition. The nozzle sprays over the exposed surface of the solid block, dissolving a portion of the solid...

Problems solved by technology

However, when the temperature of the diluent - usually water - increases, the amount of attack on the solid increases, increasing the concentration of the applied solution
