DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a device for disintegrating material, especially from the vegetable or the animal kingdom like e.g. fruit, vegetable, meat products and corn, by means of a disintegrator which is displaceable driven in relation to a dolly.
Prior art disintegrators for material that are designed for slicing e.g. fruit, vegetables and meat products, for disintegrating e.g. compostable material, for grinding down e.g. corn and seed, for mashing e.g. cowberry or other berries in order to produce e.g. raw mashed cowberry or for cutting/chopping e.g. straw, grass or other plant material have so far disclosed small effective work surface, have been noisy, have been power consuming, have been operating at high speeds, have been difficult and complicated to handle and to clean, have been generating a lot of heat and have been made up of a lot of components.
The main object of the present invention is therefore in the first place to solve among other said problem by means of efficiently functioning means.
Said object is achieved by means of a device according to the present invention, which is mainly characterized in that a rotatable driven reception disc for material supports a plurality of displaceable driven disintegrating knives which are excentrically journalled, i.e. that its axis of rotation is radially displaced from the axis of rotation of the reception disc and that the dolly is arranged along the circumference of the reception disc and along the path of motion of said disintegrating knives.
The invention is described here below as a preferred embodiment, wherein is referred to the accompanying drawings in which:
FIG. 1 shows in a perspective a disintegrating device partly in section, and
FIG. 2 shows in a cross section view a part of the disintegrating device.
A device 1 which is designed in accordance with the present invention which is intended for disintegrating material 2, especially from the vegetable or the animal kingdom like e.g. fruit, vegetables, meat products and corn, by means of a disintegrator 4 which is displaceable driven in relation to a dolly 3, has a rotatable driven reception disc 5 for material 2. Said reception disc 5 supports a plurality of displaceable driven disintegrating knives 4 which are excentrically journalled relative to a drive shaft 6, i.e. the axis 7 of rotation of said disintegrating knives is radially displaced from the axis 6 of rotation of the reception disc 5. The dolly 3 is by that arranged to extend preferably unbroken along the circumference 8 of the reception disc and along the path of motion 9 of said disintegrating knives. The rotation of the reception disc 5 is accomplished by means of a not shown motor, which transmits the drive force via the shaft 6 to said disc 5, which is attached to the shaft 6 by means of draw key. The distance A between the dolly 3 and the reception disc 5 is variable by moving them relative to each other. The dolly 3 is located at the bottom end 10A of an input member 10, which may be cylinder shaped or have any other suitable shape, e.g. conical, and which is arranged for internal reception of material 2 which should be disintegrated by means of the knife/knives 4. The dolly 3 is also located at an inner end 11A of a machine chassis 11.
A disintegrating knife 4 having a circular outer periphery is provided with a diameter D which exceeds the radius R for the active internal member 12 of the reception disc 5 which is limited by said dolly 3.
According to a not shown preferred embodiment, a plurality of disintegrating knives, having circular outer periphery, are evenly distributed along the rotational axis 6 of the reception disc. The respective diameter of the knives is thereby equal to or less than the radius of the active part of the reception disc which is limited by said dolly.
The respective disintegrating knife 4 is preferably driven by means of a drive apparatus with a speed which enables the circumference 4A of the knife 4 to cover a distance which is at least as big as the length of the inner diameter d of the
