Abstract: In a production of liquid food product from protein containing solid food, some enzymes may produce undesirable off-flavor volatiles. Grinding solid food in a liquid under pressure achieves inactivation of enzymes over a wider window of operating temperature than possible in ambient pressure. It also permits proper cooking operation to be performed simultaneously with the grinding. A grinder operated under pressure eliminates certain components and allows the use of come low cost components, such as for making soymilk from soybeans.

Abstract: A continuous production of gelatinous products by coagulation of such material as soymilk is described. There is significant variation of quality of product dependent on the human factors. Soymilk and a coagulant are transported through a holding tube at a preset rate so that a mixture of soymilk and coagulant remain in the holding tube for a predetermined period of time to effect coagulation. A perforated vertical tubing is used for separating gelatinous product from liquid and pressing it by its own weight.

Abstract: A fluid flow device is described. A rotor of the fluid flow device has one or more bubbles such as open-ended scoop cups in a rotor disc. The rotor is located in a shroud. In the case of a compressor, the rotor is driven by power and upon rotation, scooping action of the scoop cups generate fluid flow through the rotor. In a power plant configuration, high speed fluid flow drives the rotor and the power is generated on its shaft. In another embodiment, a stator is also provided in the shroud. The stator also has one or more inlet cups and outlet cups to produce desired fluid flows through the stator. In further embodiments, multi-stage fluid flow devices are described in which one or more rotors and stators are alternately located in the shroud which is substantially axially symmetrical.

Abstract: Pasteurization and sterilization of a flowable material such as food is performed by means of pulsed electric field. The flowable material is passed through a pair of closely spaced narrow electrodes at a high speed. The electrodes are applied with a continuous high electric potential. Because the material spends a very little time between the electrodes, it experiences a short pulse of a high electric field which electrocutes bacteria in the flowable material.

Abstract: The invention relates to a reverse centrifugal filter and a method of separating solids particles suspended in a liquid. The reverse centrifugal filter of the invention contains a rotatable filter screen in a filter vessel. As the filter screen rotates, solid particles in a liquid which may accumulate on the filter screen are thrown away from it, thus keeping the filter screen alway clean for efficient operation.

Abstract: The invention relates to a soaking system for solids. The system includes stacked tanks each of which has a conical bottom. The tanks are connected through perforated valves through which the solids move from the top and water is fed from the bottom. The solids are soaked in a counterflowing water. In one embodiment, two or more similar units are stacked one upon the other for more efficient operation.

Abstract: A grinder of solids or solids in liquids has a multiple milling stages. A rotating disc plate carries cutting elements on one side and hammer elements on another, both located at the circumference of the disc plate. The disc plate is rotated in a screened chamber to which the solids or the liquids containing solids to be ground are introduced. Ground product or slurry containing disintegrated solids is passed through the screen before discharged. The use of disc plate and milling elements reduces required torque, leading to improved energy efficiency and results in better performance of the grinder.

Abstract: An automatic food processor for producing an aqueous extract of protein and oil containing seeds is disclosed. The processor includes a cooking facility as well as seed griding mill and a screened filter. In one embodiment the filter is a centrifuge screen. The processor allows airless griding of seeds, thus ensuring an oxygen-free environment for seed disintegration to produce an aqueous extract which has no off-flavor, bitterness or chalkiness.

Abstract: A method is disclosed for producing protein foods and edible oils from protein and oil containing seeds which comprises disintegrating the seeds in an oxygen-free environment, such that air is prevented from entering in and mixing with said environment, to prevent seed enzymes from producing off-flavors and bitter taste without heat treating seeds to inactivate the enzymes and concomitantly insolubilize the seed proteins. Artificial milk extracted from soybeans using this method has no-beany flavor, bitter taste, or chalkiness. Flaking of soybeans employing this method gives bland flakes without denaturing proteins. Such flakes are suitable for making highly functional palatable protein foods.

Abstract: This invention describes a pulsed plasma pinch x-ray source. In the device the initial plasma annulus is derived from an electrical gas discharge in a chamber having constricted openings arranged on a circle. This low mass plasma annulus is imploded and pinched by passing high current axially through said annulus. The hot and dense pinched plasma copiously emits x-rays and has the capability of being fired at high repetition rates. The device is simple for commercial applications, such as x-ray lithography.

Abstract: With the intent of satisfying the requirement of x-ray lithography a plasma pinch x-ray source has been developed in which the initial plasma annulus is derived from a plurality of electrical arcs in vacuum. This gives a low mass liner for the standard imploding plasma liner configuration to emit suitable x-rays and has the capability of being fired at repetition rates of 10 pps or more. The simplicity of this source design is especially attractive for a commercial use environment.

Abstract: An equipment is described to produce soymilk without the undesirable beany flavor and bitter taste of ordinary soymilk. The equipment comprises grinding soybeans totally in an aqueous medium at room temperature without trapping any air, cooking the resulting slurry, and separating the undesolved solids to extract soymilk. The fact that no heat needs to be given to soybeans prior to or during the grinding operation, yields very high percentage of solids in soybeans as dissolved solids in soymilk without rendering chalkiness found in the soymilks made employing the hot-grind and blanching methods. The equipment can also be used for making bland nutritional extracts of other protein rich seeds which are known to give rise to flavor problem in foods made from them.
