Definitions

  • the invention relates to a device for the thermal treatment of food, with a treatment room and with an endless conveyor belt for transporting the food, which is at least partially linear and partially arcuately arranged in the treatment room running, wherein the conveyor belt has transversely to the conveying direction extending chain segments, the at least one side are formed slidably.
  • Such devices are known as spiral or Oval malsysteme.
  • the food to be treated are placed on the conveyor belt, which consists of a plurality of chain segments and covers a longer distance in a treatment room.
  • the transport speed together with the length of the path defines the residence time in the treatment room.
  • the food is then frozen, cooled, heated or heated.
  • the conveyor belt is mainly spiral, the individual chain segments move one another into each other and thereby compensate for the difference in length of the inner and outer curved path of the conveyor belt.
  • a disadvantage of such spiral conveyors is that the contour of the chain segments may be undesirable on the surface of the food.
  • the telescoping of the chain segments results in a transition of a movement of the belt in an arcuate to an undesirable deformation of stored on the compressed areas foods.
  • the invention has for its object to provide a device of the type mentioned, in which the disadvantages mentioned are reduced.
  • the invention solves this object by a device having the features of the preamble of patent claim 1, which is characterized by one or more food supports on which food can be stored and which are arranged supported by the conveyor belt.
  • the object is further achieved by a conveyor belt with such food pads having the features of claim 19. Further advantageous embodiments are contained in the subclaims 2 to 18.
  • the partial displacements of the chain segments of the conveyor belt into one another are no longer dependent on the transferring food.
  • the food to be treated are decoupled from the compression and extension of the conveyor belt. This ensures at the same time that not accidentally impressions of the conveyor belt are transmitted to the food.
  • At least one food support is connected in a preferred embodiment of the invention via at least one connecting element with the conveyor belt. This ensures that the food backing does not fall unintentionally from the conveyor belt, especially when the conveyor belt is turned to its return by 180 ° about a transverse to the direction of rotation guide roller.
  • each food support is connected via exactly two connecting elements with the conveyor belt.
  • the connection between the food support and the conveyor belt is ensured.
  • no more connecting element is used as required, which can save costs.
  • the provision of only one connecting element per food support may be sufficient, for example, in case of rigid food supports, or else more than two connecting elements may be advantageous.
  • connection of the food support with the conveyor belt via the connecting elements is detachably formed. This ensures that the life to be treated in each case - A - medium and adapted to the treatment itself food supplements can be used.
  • the food pads preferably on an air-permeable fabric on which the food can be stored.
  • the baked goods dispose of the food documents well and the food is also ventilated from below.
  • a web of moisture absorbent material such as cotton, hemp, linen or a microfiber, results in moisture released from the food being carried away from the food surface and not becoming undesirably between the food and the food pad.
  • the food pads are preferably formed liquid impermeable. This ensures that liquid of the food remains in or on this and does not undesirably get on the conveyor belt and possibly even impair its functionality.
  • Vorfroster previously required in the art for freezing which are used to freeze the moist surface of food before these foods get into the actual main freezer, thereby unnecessary. The acquisition and maintenance costs of such Vorfroster and the space required for this additional space can be saved.
  • the food backing preferably has a Teflon coating on which the food can be stored. This ensures that the food does not stick to the hitherto usual in this area noble stables for transporting the food and thereby adversely affects the conveyor belt. It also prevents food to settle in the mesh of the conveyor belt.
  • the food supports are designed flat. As a result, food of different shapes without exchange of food documents are conveyed.
  • the food supports are preferably formed in a longitudinal section on one side trapezoidal.
  • the support surface of the conveyor belt is optimally utilized in the region of the curved course of the conveyor belt.
  • the food supports have a profiling.
  • the profiling deliberately desired impressions can be applied to the food to be transported.
  • certain patterns such as simulated imprints of grill bars, or even markings, such as individual letters or logos, are applied.
  • the food supports are connected via one or more connecting elements with exactly one chain segment. ment connected.
  • a complete decoupling of the food supports of hinge movements of the conveyor belt is achieved in the conveyor belt level.
  • a food support is associated with more than one chain segment. The changing as a result of a telescoping chain segments distance between two connecting elements, which are assigned to different chain segments, is then compensated by the food backing itself or by the design of the connecting elements.
  • the connecting element are each arranged in the forward direction in the conveying direction of the food supports.
  • this undesirable folding of the food backing is prevented if it is reversed by a return movement of the conveyor belt, wherein the food support is transported hanging on the conveyor, again by 180 ° over a transverse to the direction of conveyance guide roller, so the food base changes from a hanging position to a position lying on the conveyor belt.
  • the connecting elements are arranged on the half of the longitudinal extension of the food support in the conveying direction. In the event of an overlap of adjacent food supports, the frictional forces acting on the food supports by sliding chain segments into one another are thereby evenly distributed on the underside of the food support.
  • the connecting elements are formed by hinges which connect the food supports pivotally about a transverse to the conveying direction pivot axis with the conveyor belt. In particular, when used in rigid food supports this is a deflection of the conveyor belt perpendicular to the conveyor plane during a return of the conveyor belt possible. The food documents are then each perpendicular to the conveyor track.
  • adjacent food supports at a distance from one another, which always excludes an overlap of food supports, so both during a linear and an arcuate movement of the conveyor belt. This eliminates the possibility of adjacent food pads rubbing against one another, thereby damaging a surface of the food base. In addition, food can not fall vertically between two documents where other climatic conditions prevail. Also, a simpler cleaning of the food documents is possible without this from the conveyor belt.
  • adjacent food documents are arranged in some areas overlapping.
  • This embodiment is particularly advantageous when very small bulk material is placed on the food supports, since there are no gaps between the documents. Food can not get into the conveyor undesirably.
  • the longitudinal extension of the food supports in the conveying direction is less than or equal to twice the transverse extent of the conveyor belt.
  • the food supports are arranged with advantage in the conveying direction one behind the other on the conveyor belt.
  • the longitudinal extension of the food supports in the conveying direction is at the same time greater than or equal to 1.5 times the extension of a chain segment in the same direction.
  • the device advantageously has an air temperature control device, which is designed to guide the air laterally over the conveyor belts. As a result, the air flow is not hindered by the food documents.
  • the conveyor belt is laterally non-positively and / or positively driven by drive elements, in particular of at least one rotating, vertical drum.
  • the conveyor belt is arranged in the form of a circular or oval spiral around the drum or drums.
