Precision measurement dispenser

A storage dispenser unit comprising:

• a canister having a storage compartment therein for receiving and holding a quantity of material to be dispensed;
• a vacuum pump operatively connected to the canister to draw a vacuum on the material in a storage compartment;
• a dispensing section operatively connected with the canister for receiving a quantity of material from the storage compartment of the canister and for dispensing the material from the dispensing section;
• an electronic controller having an input section for receiving data and an output section for directing the operation of the dispensing section;
• and
• a keypad for data entry to the electronic controller,
• wherein:
• the input section of the electronic controller is configured to receive data from the keypad indicating a type of ingredient of the material and a desired quantity of material to be dispensed expressed in volumetric units,
• a processor of the electronic controller is configured to convert the desired volumetric units of the type of ingredient to corresponding mass units of material to be dispensed, and
• the output section of the controller is configured to output a control signal to the dispensing unit to cause the dispensing unit to dispense the desired quantity of material by mass.

A storage dispenser unit comprising:

• a canister having a plurality of storage compartments therein for receiving and holding quantities of a plurality of materials to be dispensed;
• a dispensing section operatively connected with the canister for receiving a quantity of material from at least one of the storage compartments of the canister and for dispensing the material from the dispensing section;
• an electronic controller having an input section for receiving data and an output section for directing the operation of the dispensing section;
• a scale for weighing material dispensed by the dispensing section, the scale being operative to provide feedback to the controller for monitoring a quantity of material dispensed from the dispensing section;
• an electronic storage operative to store volumetric unit to mass unit conversion factors for each of the types of ingredients of the materials to be dispensed;
• and
• a keypad for data entry to the electronic controller,
• wherein:
• the input section of the electronic controller is configured to receive data from the keypad indicating a selected type of ingredient from among the plurality of materials and a desired quantity of the selected material to be dispensed expressed in volumetric units,
• a processor of the electronic controller is configured to convert the desired volumetric units of the type of ingredient to a corresponding mass of selected material to be dispensed, wherein the processor accesses the electronic storage in directing operation of the dispensing section, and
• the output section of the controller is configured to output a control signal to the dispensing unit to cause the dispensing unit to dispense the desired quantity of selected material by mass.
