SK279475B6 - Peel separator - Google Patents

Abstract

A separator consists of two inclined, independent, freely vibrating sieve boxes (1.1, 1.2) which are provided with replaceable sieve entries (2). The sieve entries (2) are provided with an upper sieve outlet and an entirely sealed double electrical separator, which are positioned at the back of the said sieve entries. Funnels are part of a double electrical separator, the rollers (5) of which are located beneath the electrode holders (6) material pick-up funnel (7) with separators (8). The region of the lower sieve underneath the lower sieve box (1.2) is directly connected to a fraction (KK) of small cores.

Description

Technical field

The invention relates to a skin separator with oscillating sieves and cylindrical separators operating on the principle of an electro-separator, for grading grain size and separating the skin and 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 rapeseed peeling devices. It consists of an air separator and a plastic-coated cylinder, which are paired with a roller brush and finally a vacuum separator is connected.

DE-OS 21 35 173 discloses a rapeseed husk 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 skin does not completely separate.

For these reasons, a different principle is used to separate sunflower seeds.

DD 108 042 discloses a peeling and sorting device. It is assumed that the classification of husked seeds is not necessary and that dust separation can also be omitted.

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

The sorting centrifuge according to DE-OS 28 34 217 likewise has such skin fractions.

The peeling and separation process is also known and used, characterized by a hydrothermal pressure treatment followed by high-frequency drying and addition of an antioxidant and synergist.

Furthermore, a number of oscillating screens for separating husks from seed mixtures are known, see for example DE-PS 14 31 430. In general, separation is only satisfactory if there are strictly defined size ratios and, in particular, size differences between husks and cores.

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

SUMMARY OF THE INVENTION

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

This problem is solved by the fact that the hull separator consists of two independently oscillating, obliquely arranged sieves, equipped with replaceable sieves, provided with an outlet of a supernatant and a completely encapsulated twin electric separator, the separating areas of which consist of The electrode holder with electrode and the divider are positioned symmetrically. In this case, the region of the underneath the lower sieve box is connected directly to the fraction of small cores.

BRIEF DESCRIPTION OF THE DRAWINGS

The invention is further elucidated in the accompanying drawing showing a schematic of a skin separator according to the invention.

DETAILED DESCRIPTION OF THE INVENTION

Two independently oscillating, obliquely positioned closed net cabinets 1.1, 1.2 are housed in a frame bolted from section steel. Both the upper net cabinet 1.1 and the lower net cabinet 1.2 are located on the oscillating shaft and are driven by individual V-belts. The mesh hinges 2 are provided with sieves having apertures corresponding to the grain size of the shelled sunflower seed. Each network cabinet 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 twin electric screen. Output hoppers 7 with separators 8 are assigned to the cylinders 5 of the double electric sorter under the electrode holder 6 with the electrode.

The function of the device according to the invention is as follows. After peeling the seeds, the peeled mixture continues through the inlet 3 to the upper sieve box 1.1. The oversize from the upper sieve box 1.1 is fed as a coarse fraction directly to the inlet hopper 4, and a double-sided electric classifier consisting of a cylinder 5, an electrode holder 6 with an electrode and splitters 8 separates the downwardly extending fractions of coarse hulls and UK. The function is described in detail in DD 108 042. The sieve from the upper sieve box 1.1 is fed as a middle fraction to the lower sieve box 1.2, whereby the sublime is divided equally by an electric separator into the KS small shell fraction, KK small core fraction and KZ interfraction. The lining of 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.
