CZ285504B6 - Husk separator - Google Patents

Abstract

The shell separator is provided with two inclined, freely oscillating, independent and superimposed net boxes (1a, 1b) with a replaceable screen insert (2). The network housings (1a, 1b) are provided with three outlets which are formed at the front and rear ends of the upper net housing (1a) and at the rear end of the bottom net housing (1b). In doing so, the output of the front end of the upper network housing (1a) and the rear end of the lower network housing (1b) is connected to the two electric shifters and the rear end output of the upper network housing (1a) is connected to the opposite electrical shaker. Each electric gripper is formed in a separate housing and a cylindrical gripper connected to the opposite structure is attached thereto.

Description

Technical field

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an oscillating screen separator and cylindrical separators operating on the principle of an electric separator for grading grain size and separating the husks of husked sunflower seeds.

BACKGROUND OF THE INVENTION

A variety of oilseed separators and separators are known to those skilled in the art.

DE-OS 21 66 149 discloses a separator for a rape seed peeling device. It consists of an air separator and a roller covered with plastic, which are paired with a roller brush and finally a vacuum separator is attached.

DE-OS 21 35 173 discloses a rapeseed sorter consisting of a set of rollers. This principle is not suitable for the separation of sunflower seeds, since peeling produces very many core breaks and the husks are not completely separated.

For this reason, another prince is used to separate sunflower seeds.

DD 108 042 describes peelers and sorting equipment. It is assumed that the classification of peeled seeds is not necessary and that dust separation may also be omitted.

In practice, however, this equipment did not prove functional, the separation was inadequate, the proportion of husks in the core product was much over 15%.

The sorting center according to DE-OS 28 34 217 also has such skin fractions.

DE-OS describes the peeling and separation method used, which is characterized by a hydrothermal pressure treatment followed by high-frequency drying and the addition of an antioxidant and synergist.

Further, a variety of oscillating screens for separating husks from a seed mixture are known. for example DE-PS 14 31 430. In general, separation occurs satisfactorily only when there are exactly defined size ratios and, in particular, the size differences between the shells and the cores.

EP 081 072 discloses an oscillating trough with a fluidizing device for separating a bulk mixture. Sorting is carried out on the basis of different density. Size classification must first be performed to ensure proper operation. This problem is solved in EP 0 162 014, but a downstream and energy-intensive device.

SUMMARY OF THE INVENTION

SUMMARY OF THE INVENTION It is an object of the present invention to provide a husked sunflower seed separator which is characterized by its small construction size and reduced power consumption and separation rates of less than 12% of the husk in the core product.

This problem is solved by the fact that the skin separator consists of two independently oscillating, slanted stacked sieves equipped with replaceable sieve hinges which are provided at the rear end with a supernatant outlet and a completely encapsulated twin electric separator whose separating area consists of the cylinders, the electrode holder with the electrode, and the dividers are symmetrically positioned. In this case, the sub-network area below the lower screen box is connected directly to the small core fraction.

Overview of the drawings

The invention is further elucidated by way of example of a shell separator scheme.

DETAILED DESCRIPTION OF THE INVENTION

Two independently oscillating, obliquely positioned closed mesh boxes 1.1, 1.2 are mounted in a frame bolted from section steel. Both the upper sieve box 1.1 and the lower sieve box 1.2 are located on the oscillating shaft and are driven by individual V-belts. The screen curtains 2 are provided with screens having apertures corresponding to the grain size range of the dehusked sunflower seed. Each sieve box 1.1, 1.2 is provided at the rear lower end with an outlet which opens into a respective inlet hopper 4. The inlet hoppers 4 are part of a mirror-shaped double electrical sorter. To the cylinders 5 of the double electric sorter are assigned under the electrode holder 6 with the electrode of the output hopper 7 with the dividers 8.

Device features:

After the hulling of the sunflower seeds, the peeled mixture continues through the inlet 3 into the upper sieve box 1.1. The overhead screen from the top sieve box 1.1 is fed as a coarse fraction directly to the inlet hopper 4 and by means of a double electric separator consisting of cylinder 5, electrode holder 6 with electrode and divider 8, the coarse husk GS fraction and UK unpeeled cores. The function is described in detail in DE 108 042. The undersize from the upper sieve box 1.1 is fed as a middle fraction to the lower sieve box 1.2, whereby the oversize sieve is also electrically separated into the small shell KS fraction, the small core KK fraction and the KZ intermediate fraction. The sieve from the lower sieve box 1.2 is fed directly to the fraction KK of the small cores as a small fraction, consisting essentially of sunflower meal.

Claims (1)

PATENT CLAIMS Peel separator with oscillating screens and cylindrical separators, working on the principle of electro-separator, for grading according to grain size and husk separation of husked sunflower seeds, characterized in that it consists of two independently oscillating, obliquely placed screen boxes (1.1, 1.2) fitted with replaceable sieve hinges (2), which are provided at the rear end with an outlet of an oversized, and completely encapsulated, double electrical sorter, the separation regions of which consist of a cylinder (5), electrode holder (6) and electrode divider (8); are located symmetrically, whereby the overspeed outlets of the two sieve boxes (1.1, 1.2) are connected to one of the two separator areas of the electric screen, and the undersize area below the lower screen box (1.2) is connected directly to the outlet of the small cores.
