Abstract: A cracking and shelling mechanism for nuts is provided with first and second elongated parallel blocks and a seesaw element which moves the blocks. The seesaw element includes a fixed central rotation shaft and rods respectively connected to the central shaft and the first or second block to cause movement of the blocks.

Abstract: A dehulling system for soft-shelled nuts includes at least two dehulling stations arranged in series, where each station is made up of at least one dehulling machine in a first dehulling stage and a screening machine in a second screening stage, both being a first and a second consecutive stages. The screening machine is a densimetric separator located lower than the dehulling machine and has an upper product inlet towards the interior thereof, which comprises a drum arranged according to an inclined plane, a first outlet for the dehulled grain in the upper part of the drum and a second outlet for the rest of materials other than the dehulled grain in the lower part of the drum.

Abstract: A machine for the integral processing of hard or soft shelled nuts herein proposed comprises a feeding hopper and at least one receptacle having a first end for connection to said hopper and a second opposite end, where said receptacle is located in a horizontal position according to the longitudinal direction of the machine and comprises therein a central shaft located according to the longitudinal direction thereof and connected at one end to a rotating element, where said central shaft has finger-like elements projecting radially outwards from various longitudinal positions thereof.

Abstract: The invention relates to a conditioning/moisturizing device for almond grains, especially designed to provide the grains of the fruit with the elasticity required in order to cut the grain into flakes, sticks, cubes or other configurations, with minimum loss through production of flour and others. The device essentially comprises an elongate body, with a generally cylindrical shape and tilted position, which includes on the inside thereof a means for sweeping the almond, made up of a spindle which sweeps the fruit in an upward direction in a steam-saturated environment with controlled temperature, for which purpose the cylindrical body comprises a plurality of steam injection nozzles, said steam being distributed externally and fed to said nozzles from an external steam distributor. The device includes temperature and steam sensors whose measurements are suitable for regulating the rotating speed of the spindle in order to adjust the time during which the almond remains in the environment inside the body.

Abstract: A device for regulating and adjusting a distance between pairs of adjacent rollers in a peeling machine for almonds and similar dried fruits is provided, wherein the rollers are horizontally aligned at both sides of a central plane through which the product to be peeled is passed, the device including a movement transmission shaft coupled to each pair of adjacent rollers, a motor for operation of the movement transmission shaft, wherein the motor is coupled to one of the ends of the transmission shaft, a torque meter for measuring torque at various positions of the rollers, wherein the torque meter is coupled to a spin axis of at least one of the rollers in the pair, and a sensor for measuring and regulating a working distance between the rollers, wherein the sensor is coupled to at least the other roller in the pair.

Abstract: A shelling-separating machine for almonds and other soft-shelled nuts is provided incorporating operational and functional features which ensure the obtaining of the kernel in optimal conditions, while at the same time allowing for an effective separation of the almonds and other hard-shelled nuts that may accompany the soft-shelled nuts. At the inlet end, the machine provides a device for continuously feeding the product for the purpose of eliminating obstructions inside such machine. At the outlet end, the machine provides a retaining device which can be manually or automatically actuated and which keeps the outlet closed in order to retain the non-shelled product until the operational conditions recommend the actuation and opening of such retaining device to allow the non-shelled product to exit the machine, preferably by the overflow with respect to a previously established level.
