Why BLAST Changes Extraction Flow

Chill, Extract, Repeat

Workflow Breakdown Article

Chill

Purpose-built direct refrigeration gives the BLAST series fast, repeatable pull-down without relying on a continuous supply of cryogenic consumables. Final performance is confirmed against the specified batch size, starting temperature, utilities, and operating conditions.

Fast pull-down without recurring cryogenic supply

Extract

Built to re-chill and re-run ethanol between extraction cycles. Some workflows target biomass-to-ethanol ratios up to 3:1, but achievable ratios and downstream recovery depend on material, equipment, SOP, and product requirements.

Workflow target: up to 3 lb biomass per gallon

Repeat

For facilities planning around multiple centrifuges or expanded extraction capacity, Perma Cool can help scope a BLAST configuration matched to flow rate, utility profile, and uptime requirements.

  • Configured around throughput goals
  • Supports scaling beyond single-line production
  • Built around real process constraints

Application Fit

Built for teams scaling ethanol extraction capacity.

Botanical extraction facilities scaling beyond pilot throughput.

Teams transitioning from LN2-heavy cooling operations.

Operators prioritizing predictable batch temperature control.

Operational Advantage

Turn reliable process cooling into higher extraction throughput.

The Perma Cool BLAST Ethanol Pre-Chiller Series is purpose-built for ethanol extraction labs that need fast, on-demand direct chilling from room temperature to −40 °C. Engineered as a true BLAST chiller from the condensing through the process side, it helps processors increase throughput, reduce LN2 dependency, and optimize their extraction workflow.

Frequently Asked Questions

QUESTIONS?

Contact Us — Ask a Question

What temperature range do Perma Cool ethanol chillers target?

Typical process targets include operation down to approximately −40 °C depending on system configuration and facility conditions.

Why choose direct refrigerant chilling over LN2?

Direct refrigerant systems can lower recurring consumable costs while delivering stable, repeatable process cooling for extraction lines.

How quickly can this be deployed?

Lead times vary by configuration; Perma Cool aligns scope early to reduce procurement friction and commissioning surprises.

Your system, your process
