Press for squeezing agricultural Products

The invention "relates to a press for squeezing agricultural Products such as vegetable and corn maize, in particular apple corn, with an elongated closed container that can be set in rotation, the one Has filling and emptying opening and that inside of the container with at least one of the container shape-adapted, made of flexible or elastic material, with the mounting plane arranged in the longitudinal direction of the container Press membrane is provided, which the interior in a Pressure medium and press space divided.

A press with these features is scanned, with in a press container, the length of which is several times the diameter, a flat or saoh-shaped membrane made of elastic or flexible material is installed, the mounting plane approximately parallel to a is arranged by the axis of rotation laid plane. This membrane turns the container into a pressure medium space and shared a press room. The membrane can, however, also run somewhat obliquely, with two, for example such membranes can be arranged, each obliquely from a central joint attachment run outside, the pressing pressure then being inclined to the opposite one Container wall takes place. These Merabran presses have prevailed because of their particularly gentle way of working tiei low pressures, after which Filling the container with the mash into the press

Press position is brought, ea is then pressed after During the pressing process, the pressure is released and the loosening phase takes place, which is then pressed again. servant The process is repeated until the mash has been squeezed out as much as possible. After pressing out the dom, the Container emptied, so this process flow is only one allows continuous pressing. But one would like to These presses, due to their structural design3, are also available as large-capacity presses with a capacity of up to 40 tons and more can also be used as continuous presses.

The object of the invention is to design a press of the known type so that a continuous one Pressing, i.e. on the one hand the mash to be pressed continuously is added and on the other hand pressed pomace is obtained, is made possible.

This object is achieved according to the invention in that the press for continuous pressing in a cycle process can be used, the mash being continuously fed to the filling opening located at one end of the container and at the discharge opening arranged at the other end of the container is removed, and that one or more pressure stages are provided.

Advantageous embodiments of the invention emerge from claims 2 to 8.

The invention is illustrated in the following description with reference to an exemplary embodiment shown in the drawings explained in more detail.

Show it,

Press with two interconnected Press containers,

Fig. 2 is a section along the line A-A in

The press shown in Figure 1 consists of two press containers 1, 2, which in the embodiment shown are arranged one above the other. You can bring this container 1, also side by side for installation. It must then only appropriate precautions are taken to transfer the pre-pressed mash of one press container 1 to the other. ren container 2 to transport.

The press containers 1, 2 have a sack-shaped press membrane 3, the fastening plane of which runs parallel to a plane arranged through the axis of rotation. The corresponding The fastening flange is identified by the reference number 4 Mistake. This membrane divides the container space into a pressure center space 5 and a pressing space 6. The containers 1, 2 are long, in Direction of the axis of rotation extending container, in order to avoid damage to the membrane during the

Auflookeningsphase these are applied to the container wall with the help of a vacuum. The upper container 1 ″ has an infill opening 8 which is connected to one of the shafts 9 via a connector 7, the emptying opening 10 being provided at the other end of the container 1. In this upper container 1, the mash is pre-pressed The mash is pressed out in the press container 2 arranged underneath, which is provided with a filling funnel 11, at the bottom of which a screw conveyor 12 runs, which transports the mash via a filling opening ^8f into the other press container 2. The screw conveyor 12 is required because the consistency of the mash is such that pumping is no longer possible, as at the beginning of the pressing process via the stub shaft 9. A special sealing device is provided here so that the mash or juice cannot escape from the corresponding filling opening 8 during the pressing process provided, which is shown in particular in FIG.

The two containers 1, 2 are each inclined towards the emptying opening, which means that the mash is transported within of the press container is promoted.

The mode of operation of the press is such that initially at Standstill of the press drum 1 a certain amount of material to be pressed, e.g. with the help of a pump via the stub shaft 9 into the press room 6.

By rotating the press drum 1 with the membrane 5 relieved, the material to be pressed is a certain distance to the other end of the drum promoted towards. As soon as the press comes to a standstill, it opens

a pressure inlet valve and the press is under pressure set, with another loading taking place at the same time. After a specified time, the pressure is applied drained again.

Then the pressing is applied again by rotating the pressing drum 1 conveyed further until the pressed or pre-pressed material is ejected at the end of the Preßtronnnel. With everyone Rotation results in a loosening up. The pressed material in the first press container 1 reaches the Filling funnel 11, from where with the help of the screw conveyor 12 is pressed into the press container 2 in the same cycle. This is where the final pressing takes place, with the pressed Mash at the end is ejected through the emptying opening 10. So that the juice or mash does not go over the filling opening 8 «can be pushed out again during the pressing process is a special sealing device present, with a guide tube on the worm gear housing 13 14 is arranged, which has a sealing washer 15 which is provided with a rubber lining 16. At the front dc3 container 2 is arranged a counter disk 17, wherein the disk 15 is pressed against the disk 17 with the aid of a lever 18 with a fulcrum 19 and drive device 20 can be. In the pressing position, the container 2 is rotated and is, for example, in the position shown in FIG 3, the filling opening 8 'outwards through the " Disc 15, 16 is covered.

As indicated in FIG. 1, the container side of the press chamber can consist of individual cover segments lined up next to one another exist, for example in the form of half-shells (Figures 2 and 3), these half-shells for cleaning and

Assembly of the membrane J are removable · The segments can also wholly or partially form a liquid drain, these parts 21 also being covered with a filter material can.

In the embodiment according to FIG. 1, there are two such press containers shown. For example, in the first press container with a lower press pressure of, for example be worked a bar, while then worked with the final compression in the container 2 with a higher pressure will. It can also be useful to provide more than two such pressure stages. Instead of several press containers 1, 2, if necessary, a correspondingly longer press drum can also be used, in which several pressure stages are built-in, for example in the form of several independent membranes, which are subjected to different pressures can be. Instead of the conveying possibility shown in Figure 1 dt "ch inclined position of the press container 1, 2 can also be provided per se known discharge elements will. Furthermore, it is necessary and also expedient to place the press membrane in the filling or outlet zone 8, 8 'or 10 to secure against damage or tearing, wherein the compression membrane 3 is reinforced. However, a mechanical device can also be provided in addition that secures the membrane against pressure loads, e.g. by providing a corresponding cover plate, which automatically pushes itself over the filling or outlet opening 3, 8 »or 10 during the printing phase.
