Definitions

  • the invention relates to a method and a device for the separation of foreign admixtures from a product stream consisting in particular of steamed or abrasively peeled potatoes or other crops.
  • a product stream consisting in particular of steamed or abrasively peeled potatoes or other crops.
  • foreign admixtures have to be removed in order to meet the requirements for the purity of the end product and, above all, to prevent serious damage to the processing technology.
  • damage occurs, for example, on the knives of cutting devices in the French fries industry if stones get into the fast-running knives. The occurrence of such damage usually results in a longer loss of production as well as time-consuming and costly repairs to the expensive cutting devices.
  • a separation of admixtures is carried out in the swim-sink process, for example with water cyclones.
  • the differences in the specific weight between crop and admixtures cause the separation effect.
  • the separating effect is limited in the case of admixtures with the same or very similar specific weight or with admixtures with an external shape that create a buoyancy in the water flow and paralyze the sinking effect. 3.
  • electronic sorting machines are known which are used to sort by color and shape. X-ray systems that use the different penetration damping are also used.
  • the separating effect is limited, as there are foreign admixtures that are identical or very similar to the useful product in terms of color, shape and penetration damping, such as pumice, flint, certain types of pebble and limestone as well as long-term woody root pieces.
  • the known devices closest to the invention are sorting devices in the fields of agriculture and the food industry.
  • a device is known in which a discharge plate is provided in a crop to be sorted in a falling stream, which is controlled by a previous detection device and can thus be sorted into two fractions.
  • a similar sorting into two fraction streams is described in DE 27 09 905 A1, in which stones in particular have to be separated from harvested crops and in which a finger unit adjustable in two positions, for example, clears a way for the vertical diarrhea of stones.
  • Optoelectronic sorting machines bring a further improvement, as described, for example, in DE 41 27 903. Such expensive machines are mainly used as quality sorting and size sorters for crops such as potatoes, onions or carrots.
  • the principle of these selectors is that the products to be read are optoelectronically scanned individually, one after the other in a drop space by, for example, image converters arranged at 120 ° to one another. Products Damaged areas are recognized and, using suitable computer programs, an incorrectly identified product is separated from the material flow, for example by means of an air blast.
  • These sorting machines work for example with potatoes with throughput rates of up to 5000 kg / h. However, these machines are not suitable for the quality selection or size sorting of smaller-sized products in view of the throughputs required there.
  • the quality sorting of small-sized products is carried out according to the current state of the art in such a way that the products are placed on a conveyor belt at a distance from each other, where they are captured by optoelectronic image converters and at the end of the belt by appropriately controlled selection mechanisms defective products are separated from the crop flow.
  • the disadvantages of this approach are manifold. In this way, the products can overlap on the conveyor belt so that damaged products cannot be recognized at all. Products that have been identified as defective can experience a change in position as soon as they are recognized as a result of unsteady conveyor belts, so that they get into a different path and as a result are not discarded.
  • Damage points, deflection characteristics, angular momentum or the like are stored in individual, microprocessors or address areas when entering the approach zone and fed to a main coordinate processor, the output signals of which control the stepping motor and thus the separating element with different product-related directions of rotation and acceleration in such a way that a finger of the separating element hits the Product part to be sorted can be accelerated, can be braked briefly at the moment of touching the product part and can be acted upon immediately afterwards with a defined, variable, product-related acceleration.
  • a device is somewhat complex for the intended use intended for the present invention and for the throughputs and sorting tasks available here.
  • the invention is based on the object of specifying a method and a device for separating foreign admixtures from a product stream, which consists in particular of steamed or abrasively peeled potatoes or other crops, which, at high product throughputs, effectively separates foreign admixtures with a comparatively small amount Enable effort.
  • the invention is based on the discovery that, under certain conditions, all typically occurring admixtures of foreign species can be distinguished very clearly from the agricultural useful product in terms of sliding friction. It was found that, in particular in the case of potatoes peeled by steam or abrasive, significant differences in the sliding friction in the ratio of 1: 5 to 1:10 can be detected in comparison to all typically occurring foreign admixtures.
  • the essence of the invention is that a product stream containing admixtures is first introduced in a single layer and loosened onto a first moving conveyor belt and a second conveyor belt is arranged after the first conveyor belt at the discharge end, the direction of conveyance of which is determined essentially perpendicular to that of the first conveyor belt, whereby the transport speed of the second conveyor belt compared to the of the first conveyor belt is preferably increased and the width of the first conveyor belt is chosen to be less than the width of the second conveyor belt. Care must be taken to ensure that at least the second conveyor belt is given a certain minimum amount of humidification.
  • the separating effect according to the invention can also be observed with conveyor belts running at the same speed, but it is significantly improved and reaches a maximum if the transport speed of the second conveyor belt is increased to that of the first conveyor belt by a factor of 1.2-1.5 , Furthermore, the desired separation effect is increased if a sufficient distance is guaranteed on the second conveyor belt for the reduction of the sliding friction of foreign additives until the transition to static friction for these additives. This is achieved in that the width of the second conveyor belt is selected two to five times larger than the width of the first conveyor belt.
  • a prerequisite for achieving the desired goal according to the invention is that a single-layer and loosened occupancy density of the product stream on the first conveyor belt is maintained, which, based on a surface unit of the conveyor belt, does not amount to an area occupied by products and additives of 25% of the surface unit of the first conveyor belt significantly exceeds.

Furthermore, it was found that the second conveyor belt B 2 is to be given a certain minimum amount of humidification. In practice, this results automatically, at least after a certain start-up phase, since the product stream to be cleaned, in the described case of the preparation of steamed or abrasively peeled potatoes, is given up in the moist state.

Abstract

L'invention concerne un procédé et un dispositif pour séparer des substances étrangères contenues dans un flux de produit qui est constitué, en particulier, de pommes de terre pelées à la vapeur ou par abrasion ou d'autres récoltes agricoles. L'objectif de l'invention est d'offrir une solution permettant, avec un débit de produit élevé, une séparation efficace de substances étrangères, de façon relativement simple. Cet objectif est atteint par le fait que le flux de produit (K) contenant les substances étrangères est déposé en une couche et en vrac sur une première bande convoyeuse (B1) en déplacement, une seconde bande convoyeuse (B2) étant placée en aval de la première bande convoyeuse (B1), à l'extrémité de distributions (B1e), et le sens de transport de cette seconde bande convoyeuse (B2) étant sensiblement perpendiculaire à celui de la première bande convoyeuse (B1). La vitesse de transport de la seconde bande convoyeuse (B2) doit être supérieure à celle de la première bande convoyeuse (B1), la largeur (bB1) de la première bande convoyeuse (B1) doit être plus petite que la largeur (bB2) de la seconde bande convoyeuse (B2), et une certaine humidité minimale est conférée au moins à la seconde bande convoyeuse (B2).
