Abstract: A commercial warewashing system has three sections, a pre-wash section, a power wash section and a final rinse section. The pre-wash section includes a sump. A perforated plate is placed in the pre-wash section over the sump. The plate receives and transfers water and gross garbage to a perforated trough secured to the side of the pre-wash section. Below the trough is a sink which communicates with the sump. The water flows into the sink and then into the sump. The gross garbage is retained in the trough. A spiral drive in the trough moves the gross garbage from the trough to a discharge end where it is removed.

Abstract: In a warewashing machine, a power wash zone is adapted to function either in a pot washing mode or in a warewashing mode. A valve controls the flow of water into an upper manifold. In the pot washing mode when the flow of water into the upper manifold is decreased, the flow into a lower manifold is correspondingly increased. This results in an increase flow rate and pressure striking a pot.

Abstract: A dolly for use in a straight sided flat bottom conveyor pan. The dolly is comprised of a frame, a pair of inner wheels and a pair of outer wheels. The inner wheels travel on an inner track of a conveyor pan and the outer wheels travel on an outer track of the conveyor pan. The leading wheels are secured to the frame along an axis which is coincident with a radius R. The trailing wheels are secured to the frame along an axis which coincident with a radius R.sup.1. The radii define an acute angle which will vary depending upon the actual dimensions of a curve through which the dolly will travel.

Abstract: An apparatus for forming a solid cake-like detergent. A dry powdered detergent mixture is discharged downwardly as a flowing particulate stream. The particulate stream is moistened by a spray of water. The moistened particulates are collected in a container in which the detergent is solidified and formed.

Abstract: A method of making a solid cake-like detergent for ware and hard surface washing, which cake-like detergent is the product of hydration and sequestration reactions, which includes:blending an alkali metal hydroxide and a hardness sequestering agent to form a dry powdered detergent mixture;flowing the mixture to form a particulate stream;moistening the particulate stream to form moistened particulates;depositing the moistened particulates in a receptacle;and forming the solid cake-like detergent in said receptacle.
