Press for continuous drying of heterogeneous substances

The invention relates to a press for the continuous drying of heterogeneous, predominantly "liquid-containing substances: particularly pome fruits such as apples, with a feed screw and an oppositely rotating press screw of opposite pitch and with a perforated * ⁱ * cage surrounding the press screw to drain away the squeezed liquid. "■ '/ -. ·

Bine known ^^ a ^ rtige press has a short press screw with a cylindrical hub to be · trockenten fabric against a plug of previously dried Sto ff'preßt, in turn, by a conical closure ^w at the end of-between the hub and the Cage formed channel is held and the internal pressure is maintained in this channel.

Experience has shown that such a Press does not work satisfactorily when you have it with a substance with a comparatively low proportion of solid components, especially cellulose. The fabric then stops:. Moving forward, .and rotates with the snail inside

of the cage.

. The invention is based on the object of a To create a press of the type mentioned at the outset, with the.a trouble-free !, continuous pressing of the substances mentioned is possible.

To solve this problem, it is provided in a press of the type mentioned that the press screw is at least four times as long as its diameter is and has a had with over the entire length of the press screw in the pressing direction increasing diameter and / or has a variable pitch and that at the end of the press under high pressure, one inside from the belongings and outside of the cage limited opening to the Pushing out the squeezed out residue is provided.

In a press designed in this way, the internal pressure is "through" the. Channel shape generated in such a way that with progressive narrowing of the canal of the Internal pressure increases increasingly without, however, at any point in the channel the movement of the Reach the inhibiting size of the substance. The disorders described cannot therefore apply to tr et eji.

The screw press can be the same shape as that have the usual extruder presses for processing plastics. '

The invention is illustrated in the following with the aid of a schematic Drawings explained in more detail using an exemplary embodiment.

The housing 1 of the press carries a shaft 2 which a feed screw 3 and a press chord 4 are arranged one behind the other and which has a drive gear 5 at its right-hand end or its entry end carries, which with a pinion 6 on a shaft 7 in Engagement is. The pinion 6 is driven by a motor, not shown. ■

The press corner 4, which is used to generate pressure, is wedged on its shaft 2. In the embodiment shown, the press screw 4 has a constant pitch and its cable 8 has an input end located on the right in the drawing up to its output end; increasing diameter. However, the hub can also be cylindrical and a variable pitch can be provided. The Prößöchneöke 4 is surrounded by an openwork cage 9; z. B _.: from a perforated sheet, which is reinforced by rings 10. The distance between the rings IC? decreases because of the increasing pressure towards the end of the press. The feed screw 3, which feeds the press screw 4, is freely rotatable on the "Vielie 2" and is driven by a drive gear 11, which in turn is driven by the power of a motor not shown. The pitch of the feed screw 3 is constant, but just like you The direction of rotation is opposite to that of the press snow 4. Above the feed screw 3 there is a filling chute 12. Below the cage 9 and beyond its outlet end, the press is expediently set up to collect the pressed liquid or the dry residue. There is an opening at the outlet end

provided which the dry residue of the pressed Substance can escape freely. ·

The invention is particularly suitable for juicing Apples, which are preferably grated before pressing,
