Pharmaceutical Industry Pain Points We Solve

Degradation or potency loss from excessive heat during drying
Incomplete solvent removal or residual solvents in final product
Batch-to-batch inconsistency in moisture content or crystal form
Contamination risks due to open systems or poor sealing
High maintenance and cleaning burdens with legacy dryers
Inefficient solvent recovery, high energy consumption, or high solvent waste
Difficulty scaling from R&D to pilot to full production while retaining quality

Engineered for the Unique Demands of Pharmaceutical Production

Pharmaceutical materials – especially APIs and excipients often require drying under tightly controlled conditions to preserve potency, avoid degradation, and achieve required residual moisture levels. Buflovak’s equipment supports virtually every stage of pharmaceutical solids processing, including powder drying, measuring and blending flavors, drying agglomerates, and pre-tableting processes.

Drying

HPAPi’s – Pharmaceutical
API isolation, washing, & drying after synthesis or precipitation
Production of inhalable powders, granules, or bulk powders for tablets/capsules
Handling sterile or high-potency materials under controlled, closed systems
Powders & flavors
Agglomerates

Solids Processing

Filter cakes processing
Production of excipients, fillers, or co-processed excipients (e.g., lactose, salts, carriers)
Hygroscopic powders
High-viscosity slurries
Hygroscopic powders
Shear-sensitive materials – polymers, catalysts, emulsions, dispersions and more
Heat-sensitive compounds

Evaporation & Solvent Recovery

Solvent-heavy formulations used in APIs or excipients
Solvent recovery from reaction mixtures or wash streams
Solvent removal & recovery
High-viscosity solutions
Corrosive or reactive chemical intermediates
Fouling-prone streams where stable, continuous operation is needed
Solvent-containing slurries or cakes

Crystallization

High-purity crystalline APIs or intermediates
Controlled crystal size distribution and polymorphism
Solvent recovery or recycling during crystallization
Batch or continuous crystallization modes depending on volume and process needs

System Integration

Built for Your Process Ecosystem

Buflovak systems can be tailored to integrate seamlessly into existing production lines or new installations, ensuring optimal fit with:

Reactors / synthesis vessels
Filtration units (e.g., centrifuges, Nutsche filters)
Solvent recovery loops
Containment / isolation systems
Solvent recovery systems
Clean-in-place (CIP) or sterilization processes
Downstream milling, blending, or packaging systems

Advanced Evaporation & Solvent Recovery

Evaporation is often a critical step in chemical synthesis and formulation when concentrating solutions or removing solvents prior to isolation. Buflovak evaporation systems are engineered to handle a variety of materials.

These systems help enable efficient solvent removal or concentration before crystallization or drying, aligning with typical pharmaceutical process flows. 

Our evaporation portfolio includes:

Forced Circulation Evaporators
Film-type Evaporators (falling, rising film, etc.)
Plate Evaporators
Continuous or batch configurations

Crystallization & Controlled Product Isolation

For many pharmaceutical products, the physical form (crystal size, polymorph, purity) is critical to performance, solubility, stability, and downstream processing.

Temperature & Solvent-Sensitive Processes

Vacuum crystallizers or jacketed crystallizers offer flexibility for temperature and solvent-sensitive processes – a common requirement in pharmaceutical manufacturing.
