"Device for peeling hard-shelled elongated seeds"

Priority: 2o * April 1961 - Mexico * -

The innovation concerns a device for peeling hard-necked elongated seeds, e.g. safflower seeds, sunflower seeds and the like »,

stare

whereby the seeds are thrown against a stationary or moving wall so that the pods only break open when the seeds are hit against the hard wall, without the Core is damaged.

So far, seeds of the type mentioned have been peeled in machines, which were equipped with rollers which could be moved towards and away from one another and carried cutting blades. These machines however, apart from the shell, they also break the inner one Part of the seed (core), so that the complete separation of the shell from the usable inner part of the seed is only possible with particular difficulty

th is possible. It was found that about 6,.> Weight percent of fatty substances in the mass of the seed coats of Safflower seeds, sunflower seeds and the like. Remain when the known peeling machines are used because, as mentioned, the shells or parts thereof are not complete separated from fragments of the usable inner seed part

The innovation is directed to a device for cleaving seeds of the type mentioned, through which the shell is removed from the core thoroughly separated and losses of fatty substances reduced to a minimum during the treatment? also should a device for searing seeds can be created which is simple in its structure. to use and maintain and cheap is to be produced, has a high degree of efficiency and is particularly reliable in operation »

The object is achieved with a device for peeling hard-shelled elongated seeds using a rotatable centrifugal disk as well as means for supplying the peelings to be peeled to the centrifugal disk and a centrifugal disk at a distance surrounding the annular wall in that, according to the innovation, the centrifugal disk with an axial cylindrical Chamber for the supply of seeds to the centrifugal disc interacts and is provided with radial centrifugal channels, which extend from the chamber to the disc circumference and open out radially at the latter.

This ensures that the surface of the rigid, ring-shaped Wall on which the seeds hit this wall itself, is enlarged. According to the innovation, it is particularly advantageous here that the opening of the radial channels on the disc circumference fit at different heights; this allows the Yield of peeled seeds can be increased Having a special focus at the end, the innovation provides an advantageous option for the intended purpose to achieve a rupture of the seed coat without destroying the seed kernel. For this it is essential to have such seeds in align the way according to the innovation, what through the vote the size of the free sling travel and the sling speed is achieved «This is the only way to guarantee with certainty that the harder and heavier® end the seed hits the rigid wall. A wide variety of seed types and their specialty can be processed in terms of their shape as well as their structure, state of maturity and much more. «In contrast, an automatic Alignment of seeds of the present type with the purpose intended according to the innovation does not take place, since such With the known machines, the seeds hinder each other and in no way align them after being thrown off.
