  • Patent number: 5257575
    Abstract: A juice extractor for extracting juices from produce such as fruits and vegetables. The juice extractor has a base which includes a housing and a motor with a vertically aligned drive shaft. A blade basket detachably mounted on the base and rotated by the output shaft separates produce into pulp and juice, and a juice bowl surrounding the blade basket collects the juice. An interlock system keeps the motor from being turned on until the juice bowl is locked to the base and a cover is locked onto the juice bowl. Juice flows from the juice bowl through a spout to an appropriate container. A spray cap keeps juice from splashing as it pours through the spout.

    Abstract: Plant wall-rich products originating, for example, from higher plants naturally rich in pectins, algae, or from by-products, such as wheat bran, potato pulp, shells or oil works residues, and the like, are modified to contain a fraction of water-soluble polysaccharides which is higher than, in particular equal to at least twice that existing naturally, without modification of their overall chemical composition. To obtain them, water is added, if necessary to the natural product in the divided state, to form a mixture capable of undergoing a shearing treatment, and the resulting product is subjected to a shearing force before extrusion, resulting in modified products as aggregates which can be converted into powder. By means of aqueous extraction, performed directly on the extruded product, a water-soluble fraction is obtained, from which there are isolated, for example, pectins, with a degree of methylation .gtoreq.

  • Patent number: 5090306
    Abstract: For the extraction of juice pulp from fruits, berries and/or vegetables the raw material, which may consist of whole fruits, is first comminuted in a comminuting device (1) and subsequently squeezed out with the help of a press (2). Press (2) is constructed in such a way, that together with the juice separated from the raw material, a high proportion of valuable cell material is pressed off. Through this process a viscous juice pulp results, which subsequently is further processed for refining purposes, for example for the manufacture of clear juice, in a crossflow filtration device (7) which follows press (2). Through the process according to the invention the quality of the refined products as well as the economy of the unit and the yield are significantly improved, especially in connection with a recycling press (4) assigned to press (2).

    Abstract: The process for obtaining juice, especially apple juice, from a mash obtained by crushing cells is free of enzymatic or biochemical processing steps for removal of pectins and performs the juice extraction continuously. The fluid phase obtained from the mash in a continuous centrifugation process and the foam combined with pectin components floating on it are separated from each other, advantageously by a vibrating screen. This process and eventual subsequent downstream separation steps, including for example removal of residual cellulose fibrous fractions from the fluid phase by centrifugal decantation, must be completed before the reaction of pectin with oxygen begins. An apparatus for performing this process is also described.

    Abstract: A process and apparatus for drawing off deformable masses containing air, such as sausage masses. The mass is transferred in a stream from a supply space into a filling cylinder where a vacuum is generated relative to the space to remove air from the mass, and the transferred mass is then ejected from the filling cylinder by means of a piston. To transfer the mass quickly and remove air from it completely, the mass stream is guided, during its transfer into the filling cylinder in such a way that, as it enters the filling cylinder, it first moves towards the cylinder wall at an angle to the direction of the piston. Moreover, during filling the level of mass in the filling cylinder is maintained at an essentially constant filling height so that a constant volume of free space remains above the mass in the filling cylinder.
