  • Patent number: 5514391
    Abstract: The present invention is directed to methods and apparatuses for preserving fluid foodstuffs. More particularly, it is directed to methods and apparatuses for extending the shelf life of perishable fluid foodstuffs such as dairy products, fruit juices and liquid egg products, which contain significant levels of microorganisms. The improved methods and apparatuses incorporate a plurality of electric field treatment zones with cooling units between each pair of treatment zones in order to maintain the temperature of the pumpable foodstuff at a level at which microorganisms are killed in sufficient numbers and at which changes in the flavor, appearance, odor, or functionality of the foodstuff remain within acceptable ranges. For a comparable microorganism kill, foodstuffs prepared by the present process have significantly higher quality than foodstuffs prepared with standard thermal processes (e.g., ultra-high temperature pasteurization).

  • Patent number: 5514403
    Abstract: This invention is a method of substantially reducing and in some cases eliminating hazardous pathogens form the surfaces of food products. This is accomplished by moving the meat products into a treatment area and spraying the same with super heated steam preferably heated to between 250 and 300 degrees Fahrenheit for a period of 1 to 5 seconds depending on the food product being treated. The surfaces of the food products are then immediately cooled by applying a chilled fluid having a temperature of between 35 and 40 degrees Fahrenheit for a period of 5 to 10 seconds. Even though the super heated steam substantially reduces or eliminates hazardous pathogens on the surface of the food products, the cooling fluid allows such surface to maintain its natural color or bloom.

  • Patent number: 5512312
    Abstract: An oven for cooking and browning foods has heated, radiant walls. Heat may be supplied by a gas burner flame in a plenum behind the walls, with products of combustion thus being isolated from the food in the oven chamber. In one embodiment food products are continuously conveyed through the oven chamber and are either cooked or simply browned in the oven by the radiant wall heat. Fats and other materials rendered from the food products, if not fully incinerated in the oven chamber, may be transferred along with exhaust air from the oven chamber to a separate combustion chamber, for incineration. Steam or other inert gas is introduced to the oven chamber to minimize oxidation and prevent flame. An alternative wall heating system uses electric resistance heat elements inside a thin ceramic wall. In another embodiment a web-like metal conveyor of a radiant wall oven is returned through the oven in order to heat the conveyor sufficiently to put grill stripes on a product being browned, such as meat.

  • Patent number: 5510127
    Abstract: Bread is produced in a bread maker by first mixing/kneading the bread ingredients into a dough, allowing the dough to rest and then kneading the dough for a second cycle. During both kneading cycles, a motor driving a kneading blade is repeatedly bi-directionally rotated with intermittent pulses to give a randomness to the flight of the dough. After kneading, the dough is fermented during a first rise cycle. Next, the dough is preheated and degassed before it is fermented for a second rise cycle. After rising, the dough is baked at a high temperature for proper browning of the crust and then the temperature is lowered to complete the baking of the bread. Lastly, the bread is cooled at a gradual rate by intermittently actuating a heater and a fan.

  • Patent number: 5505970
    Abstract: A method and apparatus for delivering a constant amount of dough per unit time is disclosed. Successive dough blocks (5) are transferred on a first conveyor (8) at times proportional to their weights. The predetermined theoretical traveling distances of the dough blocks and the actual traveling distances of the dough blocks on the first conveyor are compared to find the change of the volume or specific gravity of the dough due to fermentation. Based on the comparison the traveling speed of the first conveyor is changed to obtain a uniform amount of the dough product, and the gap between a second conveyor (11) and a stretching roller (12) may be adjusted to increase the rate at which the dough is produced.

  • Patent number: 5498148
    Abstract: An apparatus for forming a sheet of material, e.g., dough or masa, from a supply of the material includes a pair of rotatable rollers that define therebetween a gap into which is input a dough mass and out of which is produced a dough sheet. Fluctuations in the size of the roller gap are sensed by detecting changes in the position of one of the rollers, which changes are input to a servo system that automatically corrects the position of the one roller so as to maintain the proper gap size. The one roller is movably mounted in scissor-like fashion and is easily driven by a servo motor. A cutter is provided which presses against one of the rollers to cut individual dough portions from the sheet. The ends of the cutter are subjected to a bending moment which induces a camber in the cutter. This prevents the central portion of the cutter from bowing away from the roller and ensures uniform pressure between the cutter and roller, even for applications with an extremely long cutter and rollers.
