Grading Dried Herbs

A manufacturer of herbs wanted to achieve a specific sized herb fragment for supermarket display.

Grading

A Sievmaster Multiscreen 1200 fitted with two mesh screens was used to grade and separate the product.

To client wanted to ensure the removal of oversize and fines from a dried herb. The oversize portion was to be recycled for regrind and the fines (dust) was to be used elsewhere. The client required the product to be a specific size, suitable for supermarket display.

A Sievmaster 1200 Multiscreen sieve was utilised to grade and separate the product, it was fitted with two sieve screens, the top screen removing oversize and the lower the fine product.

  • Requirement

    To client wanted to ensure the removal of oversize and fines from a dried herb. The oversize portion was to be recycled for regrind and the fines (dust) was to be used elsewhere. The client required the product to be a specific size, suitable for supermarket display.

  • Operation

    The product was fed from cutting/grind unit above and fractions of the product were then discharged into various receptacles depending on their size.

  • Solution

    A Sievmaster 1200 Multiscreen sieve was utilised to grade and separate the product, it was fitted with two sieve screens, the top screen removing oversize and the lower the fine product. The large diameter unit provided an adequate area for the product to flow out from the screen centre, so each flake of herb was presented to the screen, thus obtaining an accurate separation with minimal product losses.

    The unit was mounted upon a raised fixed stand to obtain the required discharge heights suitable for the client’s production. An enclosed top along with sleeved discharge outlets helped to prevent dust caused by the flowing product.

  • Results

    The grading sieve adequately separated the product as required with volume to spare, which resulted in the client being able to increase production rate as product demand increased.
