Definitions

  • the present invention relates to a batching and compacting machine for spinach or other leafed vegetables, and to the product obtained by said machine.
  • Such a system while guaranteeing a good compacting efficiency, uses mechanisms such as pistons, Archimedes' screws and blades, which maltreat by tearing or shredding the spinach or other vegetable leaves, producing waste strands which end up in the finished product or in the gearings or mechanism of the machine; in the first case the quality of the finished product is damaged, in the second case the production is slowed down.
  • mechanisms such as pistons, Archimedes' screws and blades, which maltreat by tearing or shredding the spinach or other vegetable leaves, producing waste strands which end up in the finished product or in the gearings or mechanism of the machine; in the first case the quality of the finished product is damaged, in the second case the production is slowed down.
  • Aim of the present invention is to eliminate said drawbacks and to provide a batching and compacting machine which permits of obtaining a batched product of excellent quality, comparable to a manually batched product, even when the amount batched is small, which machine is able to keep the leaves whole and therefore greatly limit waste.
  • number 1 indicates a pair of conveyor belts which run in the same direction, one facing the other across a substantially vertical channel 2, into which the product to be batched and compacted is introduced by means of a hopper 3.
  • the conveyor belts 1 are made in a material which is suitable for contact with foodstuffs, and are preferably non-extendably plastic-toothed in the part destined to mesh with the drawing wheels 17, while they should be of knurled rubber material in the part facing the channel 2, where the product descends.
  • the particular working of the conveyor belts 1 on the side facing the product has the aim of providing a surface having a high degree of friction in order to prevent the slipping-down of the product with respect to the conveyor belts 1, while said surface is not rough so that it cannot damage the same product.
  • Motorisation means 18 of known type moves the lower drawing wheels, while the upper drawing wheels are idle.
  • the product descends by force of gravity and is accompanied by the conveyor belts 1 towards a batching device 4 which is located at the lower end of the channel 2.
  • the conveyor belts 1 are of a width which is substantially equal to the bottom of the channel 2 and define a substantially convergent channeling of the product towards the bottom, that is towards the batching device 4.
  • the descent velocity of the product between the conveyor belts 1 is about equal to the speed of the conveyor belts 1 themselves, so that the vegetable leaves are progressively and delicately compacted without being damaged during the descent towards the batching device 4, that is without there being relative movements or slipping between product and belts.
  • the batching device 4 comprises a mobile drawer 6 equipped with two batching chambers 5 which chambers 5 slide horizontally and are solid with a pneumatic cylinder 9 which is mounted between two support bars 10.
  • the sliding of the mobile drawer 6 is done in such a way that when one of the batching chambers 5 is coaxially underneath the channel 2, the other batching chamber 5 is arranged coaxially underneath one of two pneumatic cylinders 7 whose stem causes the exit of the product from the machine through a bottom opening in the batching chamber 5.
  • the pneumatic cylinder 9, with the support bars 10 and the pneumatic cylinders 7 constitute means for the movement of the batching device 4 and for the expulsion of the batched and compacted product.
  • the batching chambers 5 are equipped with a mobile wall 11, placed in movement by pneumatic and elastic means comprising a pneumatic cylinder 12 and springs 15, which means' intervention is regulated with variable pressure between a lower limit (which can be zero in the case of non-intervention of the mobile walls 11) and a prefixed upper limit.
  • the pneumatic cylinder 12 which is mounted on the fixed frame of the machine, acts with its stem on pivoted angle arms 13 which press upon a pivot 14, which pivot 14 is solid to the mobile wall 11 and kept elastically pressed towards the maximum volume position of the batching chamber 5 by means of a spring 15.
  • the mobile walls 11 serve to compact the product further, in addition to the compacting undergone during the descent along the channel 2.
  • the batching device 4 also comprises a blade 8 activated by a pneumatic cylinder 19, which blade 8 is used to cut off the correct amount of product when a batching chamber 5 is full, and also to isolate the mobile drawer 6 from the channel 2 when the sliding process of said mobile drawer 6 is under way.
  • the batching device 4 has the aim of providing a product which is measured in pre-established portions and dimensions, for example in cubic shapes.
  • pre-decided portions are between 5 and about 100 cubic centimetres.
  • the operator at the final stage of the procedure is therefore able to place the cubes in a domestic freezer, defrosting the portions as and when needed, without waste.
  • the shape of the portions depends on the shape of the batching chambers 5, which can be for example cubic, parallelepiped or cylindrical.
  • the batching device 4 can be realised with a disc which can rotate about a vertical axis and be equipped with a plurality of batching chambers, equi-spaced and sharing the same circumference.
  • the batching chambers reach a coaxial position beneath the channel 2 and, successively, beneath a pneumatic cylinder whose stem pushes out the compacted portion: while one chamber is being filled, another is being emptied.
  • a knife or blade is envisaged, which cuts the product present in the batching chamber beneath the channel 2, separating it from the channel 2 itself.
  • Another characteristic of the present machine is that of permitting the washing of the parts in contact with the foodstuff, even during the machine's operation.
  • the invention has been used with good results for the compacting and batching of leafed vegetable product, but it can also be used for other food products, in particular meat.
