  • Patent number: 10132331
    Abstract: In a radial compressor stage for a radial compressor having a rotor side, the radial compressor stage includes a stator; and an impeller configured to rotate relative to the stator. The impeller has multiple impeller blades on the rotor side. Each of the multiple impeller blades has: a flow inlet edge, a flow outlet edge, a suction side extending between the flow inlet edge and the flow outlet edge, a pressure side, and an outer surface facing the stator. At least one groove is arranged in the outer surface of at least one of the multiple impeller blades, the at least one groove being bounded by a longitudinal web both on the suction side and on the pressure side. Each of the longitudinal webs forms a sealing tip of the respective impeller blade towards the stator.

  • Patent number: 5616356
    Abstract: Food product fibers containing moisture, particularly fiber residues obtained from extraction procedures or from a hydrolysis procedure, are milled, dehydrated and deodorized by projecting fiber residues towards a wall surface for attrition milling and simultaneously, propelling air heated to a temperature of from 200.degree. C. to 400.degree. C. towards the projected fiber residues so that the projected fiber residues are projected against the wall surface for obtaining attrited fiber and the heated air is propelled towards the projected fiber residues and attrited fiber for dehydrating and deodorizing the projected fiber residues and for entraining dehydrated, deodorized attrited fiber for collection. In a case of treating fiber residues resultant from hydrolysis of a plant substance, the dehydrated, deodorized attrited fiber is mixed with ingredients to obtain a mixture for preparing a breadcrumb product, and then, the mixture is extrusion-cooked.

  • Patent number: 5192565
    Abstract: Vegetables and fruits are heat-treated to blanch them and then cooled. The heat-treated vegetables are fermented with a lactic bacteria in the presence of water to obtain a fermented food and water of fermentation having a pH of from 3.1 to 4.4. The water of fermentation is drained from the fermented food, which then is washed. The fermented food, at a pH of from 3.8 to 4.4, then is pasteurized.

  • Patent number: 5011641
    Abstract: Shaped articles of agglomerated particulate material are prepared by conveying plates having apertures therethrough on a surface for forming, by reason of the plate apertures and the forming surface, article shaping cells. Particulate material to be formed into the shaped articles is fed into the cells, and then while the plates remain on the forming surface, the particulate material in the cells first is tamped, and then while the plates ascend from the forming surface, the tamped material is ejected from the cells onto the forming surface in a form of shaped articles.

  • Patent number: 4936200
    Abstract: An endless conveyor transporting a plurality of juxtaposed shaping plates containing apertures therethrough is positioned such that a lower horizontal run of the shaping plates is positioned above and in alignment with a portion of an upper horizontal run of a belt conveyor and such that a lower surface of the plates abut the upper run of the belt conveyor for forming, by reason of the plate apertures and belt conveyor surface, article shaping cells. Means are provided for filling the cells with material to be formed into individual articles. The plates containing material in the cells are transported to a movable ejector unit having pistons which correspond in number, arrangement and shape with the number, arrangement and shape of the apertures of the plates.

  • Patent number: 4815958
    Abstract: Apparatus particularly for agglomerating particles of different products. A rotatable drum, which has a wall which defines a cylinder and a cylinder void, is mounted on a frame in a horizontal or inclined position. The apparatus includes provision for rotating the cylinder in one direction thereby defining ascending and descending halves of the cylinder. A first part of the cylinder receives particles of a product and has means, such as projecting elements, to rotate the particles for forming a vortex of particles about an axis within the ascending half of the cylinder void such that the axis of the vortex is displaced from and substantially parallel to a central longitudinal axis of the cylinder.

  • Patent number: 4293571
    Abstract: The present invention relates to a process in which an aqueous solution of proteins is subjected to hydrolysis, the product of hydrolysis is subjected to a heat treatment to denature the proteins which it contains and, finally, the proteins are eliminated by ultrafiltration. The ultrafiltration permeate constitutes the purified protein hydrolysate.

  • Patent number: 4265924
    Abstract: The present invention relates to a process for recovering proteins from lactoserum. This process comprises subjecting a lactoserum to a heat treatment to denature the proteins present in it and then separating the denatured proteins from the other non-fat constituents of the lactoserum by ultrafiltration. Alternatively, the ultrafiltered lactoserum, i.e. the retentate, is subjected to a complementary heat treatment for denaturing the proteins.The proteins thus recovered may be used in dietetic or infant nutrition and in cheese making.

  • Patent number: 4194018
    Abstract: An aqueous soya suspension is prepared by grinding soya beans in the presence of water at a temperature of from 90.degree. to 100.degree. C. to form a dispersion of particles of which the majority have dimensions of the order of 100 to 500.mu.; heating the dispersion by the injection of steam to a temperature of from 120.degree. to 160.degree. C. thereby destroying the antitrypsin factor; and grinding the dispersion to form a suspension containing corpuscules of protein and fat with dimensions of the order of 2 to 10.mu. and cell wall debris of which the largest dimension does not exceed substantially 40 to 300.mu.. The soya suspension may be consumed as such or used as a starting material for the production of foods such as cheese or used as a base for the production of beverages such as a cows' milk substitute.
