View challenge: C-7110-0101 - Detection of unwanted material in raw Tea
Raw Tea being an agricultural product and the primary input for blending & packaging of tea may contain unwanted extraneous materials like stones, wood chips or pieces, threads, plastics and paper pieces etc. in various sizes, dimensions and densities ( higher or lower than the density of Tea). Currently we remove all such extraneous materials using different machines/ equipments. We are looking for a single standalone equipment/machine/system which will detect and subsequently remove all extraneous materials automatically versus the current system of multiple sets of equipments to remove different kind extraneous materials.

Currently we have equipments/systems to detect and remove extraneous materials. Destoners, winnowing tunnels, meshes, sifters are all independent equipments capable of handling extraneous materials of particular specifications and no integrated technology is available to handle the complete range of extraneous materials.

We have explored integrated X-ray machine. However, it could only detect and remove only extraneous materials with density higher than that of Tea. Moreover, X-ray machine was not effective post packaging as our primary packaging material has a metalized layer.

We are looking for process control with an integrated equipment / machine / system which is capable of detecting and removing all types of unwanted extraneous materials from Raw or Blended Tea.

The technology offered should
have a reasonable footprint
should not damage the tea
have a low rejection rate
be low on power consumption
be an integrated system to detect extraneous materials
have capability to handle 3 to 4 MT of teas with volume (300 cc/113 gm)/hour which is the average
requirement of teas for packaging
not have rejections of more than 0.5 %
be able to detect the extraneous materials primarily from loose teas while in motion on bed /conveyor with
product spread thickness of about 24 mm on the belt
be able to detect and remove extraneous materials pre and/or post packaging.

We are not interested in a machine/equipment that detects only Ferrous and Non-ferrous extraneous materials.
