Abstract: A mixing apparatus includes an elongated cylindrical mixing chamber having a hollow body and opposed end walls attached thereto and closing off the hollow body. A discharge port extends through the body and into the mixing chamber between the end walls. Each end wall has an inner face, an opposed outer face and a plurality of nozzle bores extending therethrough and spaced about the center of the end wall.

The bores are also skewed with respect to a radial line extending outwardly from the center of the end walls and the bores of each end wall are skewed in the same direction. In this manner, a fluid entering through the nozzle bores of one end wall will contact and mix thoroughly within the mixing chamber with a fluid entering through the nozzle bores of the other end wall.

Abstract: A continuous digesting apparatus for digesting a high viscous material such as a raw material for bean curd (for example, a Japanese food "tofu") or various kinds of soups. According to the digesting apparatus of the present invention, the digesting chamber is divided into a plurality of compartments by a plurality of partition plates each having a notch and therefore the raw material in each compartment can be sufficiently mixed and uniformly digested by the injected steam and the following raw material fed from the upstream compartment through the notch of the partition plate. This makes it possible the raw material to be uniformly heated and mixed. In addition, the partition plates can prevent the formation of bubbles of active ingredients such as protein included in the raw material and the discharge of the active ingredient from the discharging pipe.

Abstract: The constituents of a flow of thermoplastics material or the like are mixed and blended by passing the flow through a mixing structure which defines an array of elongate side-by-side passages. The passages are not all alike in that at least some of them have configurations which taper along their lengths to degrees or in directions that differ from the configurations of others of the passages, whereby the flows of fluid which discharge from the differently configured passages do so at differing velocities. As the discharging flows of differing velocities recombine to form a common flow having a uniform velocity, a desirable type of mixing and blending action results. In preferred practice, adjacent ones of the passages are tapered oppositely along their lengths to converge or diverge such that fluid flowing through the converging passages is caused to increase in velocity, while fluid flowing through the diverging passages is caused to diminish in velocity.

Abstract: Disclosed is a liquid mixer having a multiplicity of slotted orifice plates spaced apart along the flow path within a chamber. Liquid passes through and exits from the slots at a 30-60 degree angle to the exit face of the orifice plates, thereby inducing turbulence which causes good mixing.

When used for dispersing small volumes of water into oil, water is injected transversely into the oil upstream of the orifice plates, to cause initial droplet formation; and, the oil-water fluid velocity through the slots is kept in the range of 80-1600 feet per second.

Abstract: Apparatus for mixing viscous, curable liquid materials in which the compots to be mixed are fed at high pressure (up to 5000 psi) into the central longitudinal chamber of a mixing head. The inlet ducts are on opposing sides of the chamber and displaced longitudinally so that there is no mixing of the components in the upstream end of the chamber where the drive shaft enters the mixing head. The two components are forced from the chamber through rotating apertures into a rotating inner tube (rotating at up to 500 RPM). The end of the rotating inner tube is closed so that the high pressure forces the material through a multiplicity of apertures in the wall of the tube. The rotating tube is enclosed in a concentric stationary tube having a multiplicity of apertures in its walls. The material is forced through the second group of apertures into an annular outer chamber which leads to the output of the mixer.

Abstract: Crop foods such as peanuts, soybeans, peas, and the like, are ground and processed in a rapid, continuous, in-line production system. The food material is converted into a thermally processed slurry rapidly by mixing the ground food with hot water and steam and then quickly cooling the slurry, preferably in a vacuum chamber. The heat treatment stops the activity of enzymes which normally produce undesirable flavors and odors in mixtures of water and ground peanuts and other foods. The rapid cooling treatment prevents damage to protein content and simultaneously strips away any raw peanut flavor that may have developed. The continuous process produces a slurry of peanuts, or the like, without the characteristic raw peanut flavor, and the bland slurry can be further processed by drying to produce a useful food product such as flour, food extender, or the like.
