  • Patent number: 5246854
    Abstract: An attached growth biological reactor for the growth and harvesting of filamentous fungi. The reactor contains a rigid cylinder which is partially submerged and rotated in a biological medium containing nutrients for fungal growth and which as been inoculated with a filamentous fungal medium. The filamentous fungi attaches itself to and grows upon the cylinder wherein it is removed by use of a doctoring blade. The reactor can be operated in a continuous mode by continuously supplying oxygen and nutrients to the reactor.

  • Patent number: 5060483
    Abstract: An automatic apparatus for the continuous freeze concentration of liquids. The apparatus includes a heat exchanger for freezing the liquid to form a slurry of ice crystals and concentrated liquid. Communicating with the heat exchanger via a line or pipe is at least one, and preferably two, separating and rinsing columns, connected in parallel, to which the slurry is pumped for separating the concentrated liquid from the ice and subsequently rinsing the ice to remove any residual liquid therefrom. First and second receptacles are provided for collecting the concentrated liquid and the ice from the columns, respectively.

  • Patent number: 4960525
    Abstract: An apparatus and method for separating particulate solids from a liquid suspension relies upon a hydrocyclone having two radially and vertically spaced inlets in the upper portion thereof for establishing throughout the hydrocyclone concentric flow patterns of a fluid stream containing the particulate solids and a stream of wash fluid which are separately fed into the hydrocyclone through the inlets. The particles are efficiently separated and washed by passing laterally from one stream to the other as a result of inherent centrifugal or centripedal forces. Multiple hydrocyclone units arranged in a countercurrent series achieve a high product recovery per unit ratio. The invention is particularly suitable for freeze concentration of high value food products.

  • Patent number: 4031252
    Abstract: An apparatus and method comprised of a plurality of doctoring units, each of which is a pivotally supported combination doctor blade and V-shaped member, is described. In each unit the leading edge of the doctor blade is parallel to the plane of the surface of a processing belt conveying the material to be dried and the leading edge formed by the two plane faces of the V-shaped member is generally perpendicular to the plane of the belt when the unit is in doctoring position. In addition to doctoring, the apparatus and method imparts a tumbling action to the material being dried by the plowshare action of the V-shaped member. Comestibles dried with this method and apparatus can be transferred directly from the method to a puffing operation, thereby eliminating the usual time consuming equilibration period.
