Abstract

PURPOSE:To provide a long serviceable cutter to cut tough fibers of empty palm nuts after their flesh is removed. CONSTITUTION:Empty palm nuts are fed into a pair of screws (12) biting one another in a housing to cut them by means of mutual biting of the screws. Then, cyclic blades (13, 14) in the form of spectacles planted on the inner wall of the housing cut them again as if emulating said performance of the screws (12), thus the apparatus is not dependent on the sharpness of the cutting edges and serviceability thereof is improved. Furthermore, empty palm nuts also can be cut under a high steam pressure while retaining the pressure at an inlet (11) and an outlet (15) of the housing. The so-cut empty palm nuts are compressed by a compressor (29) to recover the lost oil and scraps of the compression are used as fuel or fertilizer.

Description

[Detailed description of the invention]

0001

[Industrial Application Field] The present invention relates to the production of palm oil.
More specifically, the present invention relates to an apparatus for processing empty fruit bunches produced during the palm oil production process.

0002

BACKGROUND OF THE INVENTION Empty fruit bunches are made of strong fibers and are therefore very difficult to cut. Cutting machines using various methods have been devised in the past, but all of them have problems with durability, and most factories incinerate empty fruit bunches without cutting them.

0003

SUMMARY OF THE INVENTION The present invention provides an empty fruit bunch cutting machine with excellent durability using a new cutting mechanism. The aim of this is to open up a way for the effective use of empty fruit bunches, which have traditionally been discarded. Furthermore, by connecting a screw press or the like to the cutting machine, it is also possible to recover oil adhering to empty fruit bunches and oil from unpeeled fruit, which were conventionally discarded.

0004

[Means for solving the problem] Durability can be improved by tearing empty fruit clusters with mutually interlocking screws and blades facing in the direction of propulsion by the screws, regardless of the sharpness of the cutting blades. Ta.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

[0006] Regarding palm oil production, Japanese Patent Application No. 1-2
An example is given in No. 84470.

[0007] In FIG. 1, empty fruit bunches A, which have been deflated in the palm fruit bunch processing process, are fed into a cutting machine 10 from the entrance. In the cutting machine 10, the empty fruit bunches are bitten by two screws 12 rotating in opposite directions inside the cutting machine housing via a motor M and a speed reducer R, and are sent toward an outlet section 15 and torn into large pieces. It will be done. The blade of the screw 12 can be provided with a notch 12a as shown in FIG. 2 to facilitate the biting of the empty fruit bunch, and the position of this 12a is set so as to be sequentially shifted in phase with respect to the axial direction. Effective. The torn empty fruit bunches are sent to the screw and cut by being pressed against the spectacle-shaped blade shown in FIGS. 2 and 3, that is, the spectacle-shaped annular cutting blade 13 at the front stage, and then cut by a similar blade at the rear stage with a smaller diameter. 14, and the cut pieces are taken out from an outlet section 15. The number of cutting blades 13 and 14 can be increased or decreased as appropriate.

[0008] It is convenient to directly connect an empty fruit bunch press 20 to the outlet section 15 for processing the shredded pieces. The empty fruit bunch pressing machine has a two-screw 22 structure, and cut empty fruit bunches are supplied from an inlet 21, pushed out by the screw, and compressed in a space 23 by a cone 24 provided at the outlet. The oil B adhering to the empty fruit bunches is mixed with the water in the open inner body 2.
5 and collected through the nozzle 26. The pressed empty fruit cluster pieces are separated into a cone 24 and an inner body 2 at the exit of the space 23.
It is discharged from the gap formed by 5 and comes out as compressed cut pieces C from the outlet section 27. If the above is connected to the empty fruit bunch outlet of the palm fruit bunch dehulling machine operated under high temperature steam pressure as part of the palm fruit bunch processing process, the cutter inlet part is operated under high temperature steam pressure. In addition, since the compressed cut pieces introduced into the machine 20 perform a material sealing action in which the cut pieces themselves act as a sealing material at the outlet section 27, an appropriate pressure holding means is required on the upstream side of the process. Cutting,
It is easy to press under high-pressure steam to improve the cutting and pressing effects. The compressed fragments of the space-time fruit clusters form a material seal that minimizes leakage when the device is operated under steam pressure.

[0009]

[Effects of the Invention] Unlike cutting methods that rely on sharp cutting edges, the empty fruit bunch cutting device according to the present invention uses tearing action, so devices that rely on sharp cutting edges may need to be replaced every week, for example. It is possible to significantly improve the durability of the blade. In addition, by connecting the inlet side to a steamer, etc., and the outlet side to an empty fruit bunch pressing machine, etc., processing can be performed under steam pressure, further increasing the cutting effect.
It is also possible to recover adhering oil. By providing such an empty fruit bunch cutting device, empty fruit bunches, which were conventionally disposed of, can be easily used effectively as boiler fuel, fertilizer, etc.
