Abstract: A curved cup juice extractor wherein the cup is composed of two matching sections of curved interdigitating fingers which move together arcuately to enclose and squeeze the whole fruit, during which the movement and release of the cup sections is controlled by a cam and a torsional spring, and a rapid fruit feeder system works on a principle of throwing the fruit into the curved cup as the cup opens.

Abstract: An apparatus for separating liquid and solid materials, especially for extracting juice from agricultural products, particularly from fruits, comprising a rotatably mounted press container subdivided by a substantially hood-like press or squeezing diaphragm into a pressure compartment and a press or squeezing compartment. The pressure compartment has an inlet arrangement for a pressurized fluid medium and the squeezing compartment has a juice outlet arrangement. The juice outlet arrangement possesses drainage channels at the solid-wall, preferably dome-shaped section of the container located opposite the squeezing diaphragm. The drainage channels are formed by substantially trough-shaped elements provided with perforations and arranged in spaced relationship from one another at the inside of the wall of the container.

Abstract: A process and device for separating the liquid part from the solid part of seeds, fruit and/or plants, wherein the raw material is fed into a pressure vessel which is pressurized with gas selected in accordance with the properties of the material, the pressure in the vessel is suddenly released whereby the cells of the material are ruptured from the inside outwards by the equalizing of the pressure inside the cells on pressure release, the resultant disintegrated mash is then concentrated in a continuous leaching process with cold liquid, and after separating the unusable solids, the resultant liquid is subjected to appropriate aftertreatment for recovering the final product until the pure juice, oil or sugar has reached the required quality, the solid residue being either further processed or rejected.

Abstract: A lettuce and like dryer is adapted for use with a conventional blender apparatus or other appliances such as an electric juicer having a vertical drive shaft, the dryer including an outer basket having a top opening and a bottom having a generally annular reservoir and an axial opening, engaging means at the bottom axial opening adapted to engage the housing of said blender, an inner axial stub shaft connected to gear drive means mounted in said bottom opening and adapted to engage the blender drive shaft and perforate basket means removably engaging said stub shaft to be driven thereby.

Abstract: Apparatus for treating oil-containing vegetable raw materials by the influence of moisture and heat, whereby during the exposure of a rather thin layer of the oil-containing raw materials to a moisture and heat transfer fluid, the raw materials are subjected to a loosening movement, preferably by means of a vibration.

Abstract: An extractor for extracting liquid and/or pulp from a food product, for example fruit, has a chamber with a foraminous wall surrounded by a collecting envelope. A shaft extends through the chamber and carries a number of mobile beaters which are pivotally mounted on the shaft. As the shaft rotates the beaters extend radially and can swing back if there is a build-up of product in the chamber.

Abstract: The invention relates to a novel method and apparatus to precipitate and preserve protein from the juice expressed from green leafy plants by coagulating the protein in the juice through an anaerobic fermentation process and apparatus. In addition part of the carbohydrate and non-protein nitrogen in the juice is converted into bacterial protein which increases the amount of protein obtained from the juice and particularly prevents oxidative destruction of cystine and methionine and thereby increases these limiting amino acids in the obtained protein.

Abstract: A liquid feed stock containing oil is deodorized in a semicontinuous process wherein the feed stock, in a first evacuated chamber, undergoes heat exchange with a deodorized stock in a second evacuated chamber, said stocks being circulated in their respective chambers by upwardly flowing steam introduced into each chamber between a partition, separating the two chambers, and a guide plate parallel to said partition and spaced therefrom, whereafter said feed stock is passed through a succession of steam heating stages to heat said feed stock to successively higher temperatures thereby deodorizing the feed stock and then withdrawn as deodorized stock and recirculated as deodorized stock to said second evacuated chamber to undergo heat exchange with said feed stock.

Abstract: An egg cracking machine is provided wherein a first conveyor moves a plurality of eggs past a stationary blade which severs the top portion of the egg. The top portions of the eggs are carried away by a second conveyor. The egg bottoms are emptied as the egg bottoms are inverted. The egg shells are prevented from intermixing with the emptied contents by guide rails. The egg contents are collected for use in collector means beneath the first conveyor.

Abstract: Pairs of toothed rolls form bights or troughs for reception of whole lemons or other citrus fruit. The rolls turn in the same direction, one roll of each pair turning at higher speed. An axially extending bar moves in an orbit above the faster roll of each pair to contact the fruit intermittently to move it out of the bight between the rolls and into contact with a stationary inclined wall adjacent the slower of the rolls. The motion of the bar moves the fruit axially along the wall to re-enter the bight at an axially spaced location. A pool of water submerges the toothed rolls so that the sharp teeth on the peripheries of the rolls puncture the oil cells in the peel of the fruit to release the oil into the water without seriously damaging the fruit. A single oscillating mechanism provides orbital movement for two parallel bars, each bar cooperating with a pair of toothed rolls.
