  • Patent number: 10520300
    Abstract: An optical liquid height determination system of the present embodiments includes light sensors capturing different amounts of light, based on level of liquid in the tank that blocks or limits light to particular sensors. The tank is enclosed in a container with a light source and the light sensors are installed on walls of the container. Light emitted by the light source is transmitted to the light sensors by passing through the liquid product, scattered, diffused, diffracted or reflected by the dairy product, through the tank walls which may be transparent or translucent, or from other surfaces in the container within which the tank is enclosed by. The set of electrical signals received from all the light sensors are compared against sets of calibrated signals corresponding to known liquid levels in the tank. The known height corresponding to the nearest set of calibrated signals is determined as the measured liquid height in the tank.

  • Patent number: 8622257
    Abstract: An apparatus for dispensing granulated powder, such as a fine sugar or sweetener, which uses an auger driven by a gear motor. The gear motor is controlled by a control unit on the front of the dispenser, allowing a user to select the quantity of powder to be dispensed. The apparatus comprises at least one, preferably two dispensing assemblies within the chassis, each comprising a storage bin for the powder, an inclined base, an auger member abutting the base of the storage bin and a dispensing chute. The base of the storage bin is inclined positively toward to the orifice of the dispensing chute, thereby ensuring that the powder is dispensed at a constant rate with minimized dribbling.

  • Publication number: 20090250491
    Abstract: A concentrated flavour dispensing machine having displacement pumps for delivering between a fraction of a millilitre and a few ounces of fluids having a viscosity value between 1 to 4000 centepoise is described. The dispensing machine includes a cabinet for containing a multitude of displacement pumps, where each displacement pump is realisably connected to a disposable pre-filled fluid cartridge. Each displacement pump includes a stepper motor in engagement with a threaded drive rod that is advanced or retracted by any one of several predetermined distances. The drive rod impels a plunger positioned within the disposable cartridge to dispense a volume of fluid. Flexible capillary tubes connected to the output of each disposable cartridge direct the fluid to a central dispensing area. The disposable cartridge includes an expandable plunger which draws fluid back into the cartridge when the drive rod is withdrawn after a dispense operation for drip prevention.
