DESCRIPTION:
BRIEF SUMMARY
The invention relates to a cleaning and peeling machine with an essentially vertically aligned cylinder with a plurality of orifices distributed over the wall and with a screw-like element located within the cylinder and having a conveyor screw for conveying the material to be treated.
A cleaning and peeling machine of the type described in the introduction is known from U.S. Pat. No. 4,258,069. However, in this machine, the agricultural products are fed from above, with the result that problems arise with the quality of peeling.
An installation for the treatment of agricultural products with a cylinder and a screw-like element located therein for conveying these agricultural products is known from German Pat. No. 959,144. Brushes for cleaning the agricultural products are arranged on the inner periphery of the cylinder. The agricultural products are introduced laterally on the underside of the cylinder and leave the cylinder at its top end. To ensure that perfect lateral feeding is possible, feeding has to be carried out in batches.
An apparatus for peeling plant products with a rotating receiving vessel possessing an inner wall provided with abrasion means is known from German Offenlegungschrift No. 2,743,338. The receiving vessel has the form of a cage which consists of a plurality of rotating abrasion rollers which are rotatable about their vertical axes and which are arranged in the form of a ring at a distance from one another round the panels in the cage. A shaft with deflecting discs directed outwards is provided in the centre of the cage. The agricultural products are poured on the top side into the portion between the shaft and the cage wall and fall from one deflecting disc to another. The deflecting discs are made to rotate during operation, thus ensuring that the agricultural products fall irregularly and come up against the abrasion rollers at certain intervals. After they have fallen through the cage, they are collected on the underside and conveyed away. The cage is fastened in a housing in which the skins are collected. In this apparatus, the problem arises that because of their irregular shape, the agricultural products fall onto the abrasion rollers only accidentally and unevenly and that it is even possible for agricultural products to rebound from one deflecting disc to another without having sufficient contact with the abrasion rollers. This problem is further aggravated because the products are poured in from above.
The object of the invention is to provide an apparatus of the type described in the introduction, by means of which the above disadvantages are avoided. In particular, perfect cleaning and desired peeling of agricultural products, especially potatoes and the like, is to be possible even when feeding is continuous.
This object is achieved by means of a cleaning and peeling machine of the type described in the introduction, which is characterised, according to the invention, in that, at the lower end of the conveyor screw, there is a horizontal bottom part, and a hollow cylinder which is surrounded by the conveyor screw, is open on its top side for receiving the product to be processed and the underside of which is open and is located at a distance above the bottom part.
Further features and practicalities of the invention emerge from the description of exemplary embodiments with reference to the Figures. In the Figures:
FIG. 1 shows a sectional side view of the cleaning and peeling machine;
FIG. 2 shows a plan view along the line II in FIG. 1 of a detail of the apparatus, and
FIG. 3 shows a modified embodiment of the detail shown in FIG. 2.
The cleaning and peeling machine comprises a stable housing 2. A bearing block 4 is located symmetrically in the centre on a support 3 of this housing. This bearing block carries on its top side a first roller bearing 5. A cylinder 6 is attached to the latter. The cylinder has on its outside sliding rings 7, 8 which extend over the peripheral direction and which run on sliding rollers 9, 10 fastened to the inside of the wall of the hous
