Executive Summary
A leading manufacturer of botanical active ingredients required a fully integrated extraction facility for the production of pharmaceutical-grade Berberine Hydrochloride (HCl) derived from botanical sources such as Berberis aristata and Coscinium fenestratum. The primary objective was to achieve high product purity while minimizing solvent consumption, reducing operating costs, and ensuring consistent batch quality for export markets.
MECH O TECH LLP designed and supplied a 5 TPD turnkey Berberine HCl Extraction Plant, incorporating advanced extraction, purification, pH-controlled conversion, crystallization, filtration, drying, solvent recovery, and PLC-SCADA automation.
The facility consistently manufactures Berberine HCl with purity exceeding 97%, meeting the quality requirements of pharmaceutical, nutraceutical, and herbal medicine manufacturers worldwide.
Customer Background
The customer is a producer of botanical extracts supplying ingredients to pharmaceutical companies, dietary supplement manufacturers, and international herbal product brands. Growing demand for Berberine HCl required expansion from semi-manual production to a modern automated facility capable of meeting stringent quality and regulatory standards.

Process Flow
Process Description
Raw Material Preparation
Botanical raw material is cleaned and milled to an optimized particle size, ensuring efficient solvent penetration and maximum alkaloid extraction.
Solvent Extraction
The prepared material is loaded into stainless steel extractors, where food- or pharmaceutical-grade solvents are circulated under controlled temperature and agitation.
The optimized extraction cycle provides:
- High alkaloid recovery
- Uniform extraction
- Reduced solvent usage
- Improved productivity
Filtration
The extract is clarified using pressure leaf and polishing filters to remove suspended solids before concentration.
Vacuum Concentration
Clarified extract is concentrated under vacuum to preserve heat-sensitive alkaloids while recovering valuable solvent for reuse.
Benefits include:
- Lower steam consumption
- Better product stability
- Reduced operating costs
- Improved downstream processing
Purification
The concentrated extract undergoes purification to remove pigments, tannins, and other unwanted constituents, producing a cleaner alkaloid-rich solution.
Berberine Hydrochloride Conversion
A precisely controlled pH adjustment converts purified Berberine into its hydrochloride salt, improving stability, purity, and pharmaceutical suitability.
Automated dosing systems ensure:
- Accurate reagent addition
- Controlled reaction conditions
- Batch consistency
- Reduced operator intervention
Crystallization
Controlled cooling and agitation promote the formation of uniform Berberine HCl crystals with excellent purity and particle characteristics.
Centrifugation
High-speed centrifuges separate crystals from the mother liquor with minimal product loss.
Drying
Vacuum tray dryers reduce moisture while maintaining crystal integrity and chemical stability.
Final product characteristics include:
- Moisture below specification
- Excellent flowability
- High purity
- Long shelf life
Pulverizing & Blending
Dried crystals are milled and blended to achieve customer-specific particle size distribution before packaging.
