Abstract: The starting product is rich in broken-down plant cell walls. Water is added, if necessary, to obtain a mixture suitable for the subsequent shearing treatment. The product is subjected to a shearing stress before extrusion, to obtain product containing a water-soluble polysaccharide fraction greater than that which exists in nature, without changing the overall chemical composition. The modified product is obtained in the form of crushable aggregates. If the starting product is derived from higher plants naturally rich in pectins, the latter (which have a dry matter content of at least 70%) are extracted from the water-soluble fraction by precipitation by an alcohol or by its multivalent salts. The extraction residue consists of edible fibres.

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.

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 potato chip maker comprises a heated container having a cover. The container encloses a two-piece basket including a separately supported bottom wall and a side wall. Both walls are suspended from a shaft centrally depending from the cover.The shaft is driven from outside the container by a crank through a one-way clutch and may be stepped around as the crank is pivoted back and forth over a blade in the cover. The crank has means to hold a potato which is cut into chips and other shapes by being brought back and forth across the blade. Because of the rotation of the basket, successive chips land in separate areas of the basket and do not contact and stick to each other. After the chips are cooked the basket is manually drawn upwardly above the oil for a centrifugal draining spin as the crank is again manipulated. Thereafter the bottom wall of the basket is raised separately from the side wall to a level at least as high as the top of the side wall.

Abstract: Olive oil is recovered from olives by separating olive pits from olives to obtain a pitless olive meat, by maintaining the pitless olive meat at a temperature of about 70.degree. F. to about 110.degree. F., by introducing the pitless olive meat to an extraction zone, by withdrawing a liquid phase comprising olive oil, water, and a minor proportion of pulp from a first portion of the extraction zone, and by withdrawing a substantially dry solid olive pulp from a second portion of the extraction zone. The pulp and water are separated from the oil to obtain a pure olive oil. An inert additive is mixed with the pitless olive meat before extraction to increase the yield of product olive oil. Where olive culls are used as the starting material, the culls are wetted before the pits are separated.

Abstract: A juicer having a positively rotated cutting disk for comminuting the product to be juiced is disclosed. A centrifuging disk is mounted on the same spindle as the cutting disk, but via ball bearings so that it rotates independently of the cutting disk. The centrifuging disk supports a basket which collects and centrifuges the pulp of the comminuted product. Since the basket and the cutting disk rotate at different speeds, the pulp is evenly distributed around the basket, minimizing vibration and increasing the yield. Juice drains off a depending wall of the cutting disk into an annular groove in the centrifuging disk and then out radial channels. The rotational speed of the centrifuging disk is retarded by fins which interact with the cooling air for the motor.

Abstract: A centrifuge-type apparatus for extracting, by pulverization and filtering under centrifugal force, the juice component from plant materials such as fruits or vegetables. Plant material introduced into the open top of a stationary hopper is pulverized upon contact with a series of fast-moving non-bladed, blunt protrusions extending upwardly from the surface of a rapidly rotating plate member extending across the open bottom of the hopper. The resultant juice and pulp mixture is then thrown outwardly under centrifugal force through an annular space of predetermined height formed between the bottom of the stationary hopper and the upper surface of the rotating plate. A frusto-conical filter member attached to and surrounding the rotating plate member impedes the outward motion of the pulp component of the pulverized plant material whle permitting the passage of the juice component.
