David Brian Emerson has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9095145
    Abstract: A method and system for the direct injection of a concentrated additive is disclosed. In one aspect, the concentrated additive comprises asparaginase. Because dilution of asparaginase in chlorinated drinking water can reduce the activity of the enzyme thereby making the enzyme less effective the direct injection of the enzyme into a dough can increase the acrylamide reduction in food products.
    Type: Grant

  • Publication number: 20130236601
    Abstract: Acrylamide reducing agents are added to molasses prior to heat treatment at temperatures above about 120° C. Preferably, citric acid is added to reduce the pH of the molasses, and asparaginase and/or lysine is added to the reduced pH molasses before it is heat treated at temperatures above about 120° C.

  • Patent number: 7931928
    Abstract: A method for making an expandable half-product or pellet suitable for cooking by microwave oven (or other method such as frying) that results in a non-uniform, random design, while having a distinct pattern or style. The half product design is achieved by inducing stress cracks in the half product. The stress cracks are created by a controlled drying process whereby extruded half-products are first case hardened to create an outer skin that requires an internal build-up of pressure to penetrate. After creation of the outer skin, by drying in an oven or in ambient air, the half-product is heated to permit the vapor pressure of the moisture inside the half-product to break through the outer skin and escape. Such escape points induce stress cracks in random places in the half-product. The general pattern of the stress cracks can be varied by manipulation of the time-temperature profile of the case hardening and stress cracking steps.

  • Patent number: 7156642
    Abstract: An improved dough-rolling apparatus and method for rolling sheeted dough. The proposed invention comprises a dough-rolling apparatus having a dough sheeter, a sheeting conveyor having a ramped section, a roll-initiating curtain positioned above the ramped section, and a roll-completing curtain positioned above the conveyor and downstream from the roll-initiating conveyor. Sheeted and cut dough pieces are deposited onto a steel mesh, partially-ramped sheeter belt, where two wire-mesh rolling curtains are draped onto the sheeter belt to induce rolling of the dough pieces.

  • Patent number: 7134543
    Abstract: A containment apparatus for a multi-pass oven consisting of guide rails and tapered guide chutes having side rails. A tapered guide chute directs product pieces from one conveyor to the center of a receiving region of an underlying conveyor. Guide rails are placed along the sides of the receiving region of an underlying conveyor and maintain baking product pieces on the conveyor. Diverters on the distal end of each guide rail further move product pieces toward the center of the conveyor. Such diverters help ensure that pieces reach a subsequent guide chute or subsequent conveyor without falling off of the conveyor. Such guide rails, diverters, and guide chutes help prevent damage to, and loss of, product pieces while pieces pass through the oven. Guide rails, diverters, and guide chutes are particularly effective at maintaining round or cylindrical pieces within a multi-pass oven.
