  • Patent number: 6235210
    Abstract: The present invention provides a combination continuous and batch filtration system for a recirculating fryer where the continuous filter and batch filter assemblies are integrated into a single unit, utilizing a common pump. This unit is substantially compact and is therefore able to fit within the frame of most recirculating fryers. The outlets of the continuous filter and the batch filter are connected to a two-way valve, which is, in turn, connected to the inlet of the common pump. The valve allows an operator to selectively pump cooking fluid from either the continuous filter or the batch filter back into the fryer vat.

  • Patent number: 5539672
    Abstract: A temperature control circuit which is capable of operating a microprocessor on a very low voltage source. The temperature control circuit uses a pair of field effect transistors and a zener diode in an oscillator circuit to amplify the source voltage. A microprocessor is supplied by the amplified source voltage, and is connected through a transistor to a temperature sensing portion of the circuit. The microprocessor uses the transistor to turn the power to the temperature sensing circuit portion off between temperature samples. By turning the temperature sensing circuit power off between samples, the average power drain by the control circuit is an amount that can be met by the amplified voltage from the low voltage source.

  • Patent number: 4958479
    Abstract: An elevator package wrapping machine comprises a film gripper for initially drawing fixed lengths of film into the machine. While the film is held by the film gripper and side clamps, a package is elevated into the film such that the height of the package draws a first addition to the film drawn by the gripper, if required. Film side and rear underfolders fold the lateral edges of the film and the rear edge of the film extending from the film source under the packages, respectively. A film cutter is provided for severing the film from its source as the packages are being wrapped, and the cutter is controlled such that the timing of its operation is based on package length. By timing the operation of the film cutter to correspond to package length, a second film addition may be drawn by the rear underfolder during package wrapping, if required.

  • Patent number: 4944135
    Abstract: Packages to be wrapped, weighed and labeled are fed manually into an infeed station of a wrapping and weighing machine from an operator's position. A conveyor then carries them to a wrapping station. The packages are automatically wrapped at the wrapping station and returned to a weighing scale positioned above the infeed station at the operator's position where the packages are weighed and a label is printed adjacent the weighing scale and within convenient reach of the operator. The label is then manually applied by the operator as the wrapped and weighed package is removed from the scale. The wrapping station engages in continued cyclic operation so long as there are any packages in the machine. However, the conveyor operates on a demand basis in response to the placement of packages into the infeed. When a package is sensed, the conveyor goes through one operating cycle in synchronism with the operation of the wrapping station.

  • Patent number: 4872466
    Abstract: A commercial warewasher is disclosed, in which racks of soiled ware, such as dishes, are consecutively washed through a machine cycle which includes recirculating wash water over the ware followed by a fresh water spray rinse. A portion of the wash water is drained and a second portion is intentionally retained in the machine during the rinse period after each rack of dishes is washed. The retained portion is thereby combined with the fresh rinse water to provide a volume of water sufficient for pumped wash recirculation for the next rack without cavitation, while enabling usage of a minimum quantity of rinse water required to provide effective rinsing. Reduced water consumption, reduced energy to heat the water and reduced chemical usage (detergents, sanitizers and rinse agents) are all possible in amounts and degrees depending upon the type and design of warewasher with which the method and apparatus is employed.
