Roots - White Bedstraw
Roots - White Bedstraw
Mechotech designs and manufactures turnkey natural colour extraction plants for white bedstraw roots. In the Mechotech catalogue, Roots - White Bedstraw is listed in the Pink Colour group alongside Fruit - Avacado / Cherries, Flower - Roses and Plant - Lichens. No Mechotech article, case study or legacy page describes white bedstraw: the species, the pigment, the shade and the extraction route are not stated in any source, so they are confirmed with the client before the plant is configured. Mechotech’s Pink Colour hub page records that no article describes the pigment of the pink group as a whole.
Mechotech’s Roots - White Bedstraw plant is configured around the raw material and the target colour extract. It is built in SS 316L with integrated solvent recovery, automation and full documentation, and is delivered as a commissioned turnkey system. Because no Mechotech source describes white bedstraw root pigments or a colour route, the line is specified generically for solid-liquid extraction, filtration, vacuum concentration and standardisation, and the solvent system, extraction conditions and pH are established during process development and pilot validation on the client’s root.

Manufacturing Process
Raw Material Preparation
White bedstraw root is authenticated, washed free of soil, tested for moisture and size-reduced so the extraction liquor can reach the tissue; the particle size is set during process development.
Extraction
The prepared root is extracted in closed jacketed SS 316L vessels at controlled temperature over several cycles. The solvent system, temperature and pH are not described by any Mechotech source and are set during process development.
Filtration
The extract is separated from the spent root and clarified through a plate-and-frame filter press followed by cartridge polish filters.
Concentration & Solvent Recovery
The extract is concentrated in a falling-film / vacuum evaporator, with solvent recovered through the condenser return system where a solvent is used.
Standardisation
The concentrate is assayed and adjusted to the declared target colour specification, such as shade and colour strength, with the raw material and extraction conditions held consistent between batches. The shade and pigment strength are established in trials.
Drying & Quality Control
The standardised extract is supplied as a liquid concentrate or spray- or vacuum-dried to a powder, per specification, then released after assay, residual-solvent (where a solvent is used), heavy-metal, microbial and moisture testing.

Key Features
SS 316L Construction
Electropolished SS 316L product-contact surfaces with CIP operation between batches.
Route Set on the Client’s Root
No source describes white bedstraw pigments, so solvent, conditions and shade are established on pilot runs with the client’s material rather than assumed.
Closed-Loop Solvent Recovery
Where a solvent is used, integrated condenser-return recovery reuses solvent between batches and reduces solvent loss.
Standardised to Specification
In-process and batch-release assay are used to check the finished extract against the agreed target specification, such as shade and colour strength.
Scalable Batch Capacity
Plants are configured to requirement from pilot scale upward, with modular expansion.
