Sieve-slot construction of sieves for domestic fruit-juice extractors with conical basket

摘要

The invention relates to a sieve-slot construction of sieves for domestic fruit-juice extractors with conical basket, which is produced galvanoplastically or by etching and is intended for sieves for the separation of solid-liquid mixtures into fruit juice and pulp. The aim of the invention is to achieve a slot construction which eliminates the blocking of the sieves with fibrous material and continuously guarantees the separation of fruit juice and pulp without manual cleaning of the sieves, the thin parts of the fibrous material which have entered the sieve hole being separated from the thicker parts which are situated on the sieve surface and being separated off by way of the sieve hole itself. According to Figure 1, the object is achieved in that a slot (1) has at least one asymmetrically, double wave-shaped cutting edge (2), which possesses main cutting edges (3) with partial cutting edges (4), where the length of the main cutting edges (3) to a slot length (L) is in the ratio 1:3 to 1:8, and has at least two partial cutting edges (4), a slot axis (5) disposed at an angle ( alpha ) of 10@ to 80@ to the direction of the chord of the transporting direction (T) of the liquid-solid mixture to be separated, a wave front side of the main cutting edge (6) disposed at an angle (ss) of 40@ to 60@ to the slot axis (5) and a wave rear side of the main cutting edge (7) disposed at an angle ( gamma ) of 20@ to 40@ to the slot axis (5), and a wave height of the main cutting edge (H) to ...
