Natural Colour Extraction Plants

Dried Bean - Black Beans

Mechotech designs and manufactures turnkey natural colour extraction plants for Dried Bean - Black Beans. We supply the complete machinery to process Dried Bean - Black Beans into an extract configured to the client’s target specification. In the Mechotech catalogue, dried black beans are listed in the grey-to-black colour group alongside oak galls, sumac leaves, walnut hulls, iris roots, black rice and black carrot / black currant.

Mechotech’s Dried Bean - Black Beans plant is configured around the raw material and the target extract. It is built in SS 316L with integrated solvent recovery, automation and full documentation, and is delivered as a commissioned turnkey system. Final parameters are established during process development. The hero is a crop of the raw-material area only: black beans in a sack and bowl.

Manufacturing Process

Raw Material Preparation

Dried Bean - Black Beans raw material is authenticated, tested for moisture, and milled to a uniform particle size to maximise solvent contact before extraction.

Extraction

Milled Dried Bean - Black Beans is extracted with food-grade solvent (alcohol / aqueous) in closed jacketed SS 316L extractors under controlled temperature and multiple cycles to maximise recovery of the target actives.

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 specification before the final finishing step.

Drying & Quality Control

The standardised Dried Bean - Black Beans extract is spray- or vacuum-dried, 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 its declared target specification.
Integrated Drying
A matched spray/vacuum dryer produces a dry extract powder; drying parameters are set during process development.
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 Dried Bean - Black Beans?

Yes. Mechotech supplies the complete turnkey plant for Dried Bean - Black Beans — 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 Dried Bean - Black Beans plant achieve?

The plant is configured to the client’s target specification for Dried Bean - Black Beans; the specification achieved is established during process development and pilot validation, and each batch is released with batch-release testing and certificate-of-analysis documentation.

What production capacities are available for the Dried Bean - Black Beans plant?

Capacity for the Dried Bean - Black Beans 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 Dried Bean - Black Beans plant?

The end-use areas listed for Dried Bean - Black Beans on this page are given under Applications. The end use and the target specification are confirmed with the client before the plant is configured.

Which raw material is processed in the Dried Bean - Black Beans plant?

The catalogue lists Dried Bean - Black Beans as dried black beans (exact feed form, such as whole bean or seed coat, confirmed with the client). The exact feed form is confirmed with the client before the plant is configured.

How does the Dried Bean - Black Beans extraction process work?

The milled Dried Bean - Black Beans raw material is extracted with food-grade solvent (alcohol / aqueous) in closed jacketed SS 316L extractors, clarified by filtration, concentrated with solvent recovery, standardised, dried and quality-tested.

Does Mechotech list other routes or related plants for Dried Bean - Black Beans?

Yes. Black beans are one of the raw materials in the Grey to Black Colour group, with related pages including Galls - Oak Galls, Hulls - Walnut and Grains - Black Rice. For the process background, see the article Black Bean Colour Extraction Process: Anthocyanins from the Seed Coat.

Which colour group is Dried Bean - Black Beans listed in?

It is listed in the Grey to Black Colour group with Grains - Black Rice, Galls - Oak Galls and others. Mechotech’s article on black bean colour extraction covers the pigment chemistry, and the colour achieved on a given bean supply is established during process development.
