Natural Colour Extraction Plants

Inner Bark - Red Maple Tree

Mechotech designs and manufactures turnkey natural colour extraction plants for the inner bark of the red maple tree. In the Mechotech catalogue, Inner Bark - Red Maple Tree is listed in the Blue to Bluish Purple Colour group alongside Fruit - Dogwood /Mulberries / Elderberries /Blueberries, Flower - Hyacinth / Cornflower, Foliage - Indigo and Leaves - Woad. No Mechotech source names the colour compound in red maple inner bark or the botanical species, so these are confirmed with the client before the plant is configured. The plant is configured around the raw material and the target colour extract.

Mechotech’s Inner Bark - Red Maple Tree 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. Bark is a dense, fibrous feedstock, so the line starts with cleaning and size reduction before extraction in closed jacketed vessels; the solvent system, extraction conditions and particle size are set during process development. Final parameters are established during process development and pilot validation.

Manufacturing Process

Raw Material Preparation

Inner bark is authenticated, cleaned, tested for moisture and size-reduced so the extraction liquor can reach the bark tissue; the particle size is set during process development.

Extraction

The prepared bark is extracted with food-grade solvent (alcohol / aqueous) in closed jacketed SS 316L extractors at controlled temperature over several cycles; the solvent system and conditions are set during process development.

Filtration

The extract (miscella) is clarified through a plate-and-frame filter press followed by cartridge polish filters.

Concentration & Solvent Recovery

The miscella is concentrated in a falling-film / vacuum evaporator, with solvent recovered through the condenser return system.

Standardisation

The concentrate is assayed and adjusted to the declared target colour specification, such as shade and colour strength.

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, heavy-metal, microbial and moisture testing.

Key Features

SS 316L Construction
Electropolished SS 316L product-contact surfaces with CIP operation between batches.
Closed-Loop Solvent Recovery
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.
Gentle Concentration
Vacuum concentration keeps heat exposure low for temperature-sensitive colour compounds.
Scalable Batch Capacity
Plants are configured to requirement from pilot scale upward, with modular expansion.

Frequently Asked Questions

Does Mechotech supply the complete machinery for Inner Bark - Red Maple Tree?

Yes. Mechotech supplies the complete turnkey plant for Inner Bark - Red Maple Tree — engineered, fabricated at our Hyderabad facility, installed and commissioned as a single integrated system. Final process parameters are established during process development and pilot validation.

What specification can the Inner Bark - Red Maple Tree plant achieve?

The plant is configured to the client’s target specification for Inner Bark - Red Maple Tree; the specification achieved is established during process development and pilot validation, and batch-release testing with certificate-of-analysis documentation is defined with the client.

What production capacities are available for the Inner Bark - Red Maple Tree plant?

Capacity for the Inner Bark - Red Maple Tree plant is configured to raw-material supply, confirmed buyer volume and investment timeline, starting at pilot scale; a pilot plant is recommended to validate parameters before scaling.

Which industries use the Inner Bark - Red Maple Tree plant?

The end-use areas listed for Inner Bark - Red Maple Tree are given under Applications. The end use, the colour shade and the target specification are confirmed with the client before the plant is configured.

Which raw material is processed in the Inner Bark - Red Maple Tree plant?

The catalogue lists the inner bark of the red maple tree. Mechotech’s sources do not state the botanical species, the bark form (fresh, dried, shavings) or the colour compound, so these are confirmed with the client before the plant is configured.

How does the Inner Bark - Red Maple Tree extraction process work?

The cleaned, size-reduced inner bark is extracted with food-grade solvent (alcohol / aqueous) in closed jacketed SS 316L extractors, clarified by filtration, concentrated under vacuum with solvent recovery, standardised to the target colour strength, dried where a powder is required and quality-tested. The final route and conditions are set during process development and pilot validation.

What colour does red maple inner bark give?

The Mechotech catalogue lists Inner Bark - Red Maple Tree in the Blue to Bluish Purple Colour group, and the group hub is Blue to Bluish Purple Colour. No Mechotech source states which pigment in the bark produces that colour or the shade achieved, so the pigment, shade and specification are established with the client during process development rather than assumed.

How does this page differ from Mechotech’s other bark and blue-colour pages?

This page covers red maple inner bark in the blue to bluish purple group. Foliage - Indigo and Leaves - Woad are the blue-dye leaf pages in the same group, and Flower - Hyacinth / Cornflower and Fruit - Dogwood /Mulberries / Elderberries /Blueberries cover a flower and fruit raw material. Other bark pages sit in different colour groups, for example Bark - Oak Bark / Birch in the Brown Colour group.

Where does this page sit in the natural colour range?

Inner Bark - Red Maple Tree is part of the Blue to Bluish Purple Colour group (hub page: Blue to Bluish Purple Colour) within Mechotech’s Natural Colour Extraction Plants range.
