Explosion Proof Wiped Film Distillation Equipment Industrial For High Purity THC Remediation

Turnkey Wiped Film Distillation Equipment for High-Purity THC Remediation & CBD Full Spectrum Oil

Product Overview

The WFD-C series is a purpose-built Wiped Film Distillation system for the high-throughput refinement of cannabinoid crude oils. Designed to tackle the unique challenges of removing terpenes, solvents, and heavy chlorophyllic waxes, this system is the industry’s gold standard for achieving winterization-free distillates. By employing a precise combination of chemical engineering, ultra-high vacuum, and continuous thin-film evaporation, it produces a crystal-clear, golden distillate with unsurpassed potency and clarity. For processors demanding scalable, reliable, and safe production of broad-spectrum oils or potent THC distillates, this closed-loop system delivers consistent 90%+ total cannabinoid potency in a single, efficient pass directly from winterized or even carefully handled crude oil.

Cause: The Bottleneck of Post-Extraction Cannabinoid Processing

The journey from crude ethanol or CO2 extract to a salable distillate is fraught with inefficiency. The crude extract is a complex mixture of target compounds alongside aggressive pigment contaminants, residual solvents, and high-boiling lipid waxes. Traditional boiling flasks force a compromise: high heat to evaporate cannabinoids but also destroys valuable terpenes and induces thermal decarboxylation or THC degradation to CBN. Labor-intensive winterization and filtration steps add days to processing time, creating a massive throughput bottleneck and losing 5-15% of your yield to the absorbed oil in the filter cake. This slow, batch-wise method of using static short path pots is the single biggest barrier to scaling a cannabinoid extraction business profitably.

Solution: Continuous Turnkey Cannabinoid Polishing

Our turnkey WFD solution completely bypasses the winterization bottleneck. The system’s high-torque rotor processes warm, unfiltered crude directly, spreading it into a turbulent film against a highly isothermal heated wall. Under a deep vacuum (0.001-0.01 mbar), the cannabinoids volatilize at a significantly lower boiling point, immediately condensing on a closely positioned internal hot condenser that prevents solidification. The dark, non-distillable tars and waxes flow continuously out the residue port. This single-step, continuous process transforms dark crude into a light, golden distillate in seconds, slashing processing time from days to hours and increasing yield by capturing cannabinoids that would otherwise be lost in filter media. Built as explosion-proof certified units with comprehensive PLC automation, it simplifies a complex process into a safe, push-button operation.

Specifications 

Application

• THC Distillation: High-purity Delta-9-THC refining for medicinal and recreational markets.

• CBD Broad Spectrum: Removal of psychoactives and waxes for broad-spectrum bulk oil.

• High-Terpene Extract (HTE) Separation: Gentle primary pass to separate volatile terpene fraction.

• Minor Cannabinoid Concentration: CBN, CBG, and CBD-V isolation from fractional runs.

How It Works

Pre-heated crude is metered into the system against a precisely controlled internal pressure. The rotating wipers instantly create a thin film across the glass or metal body, which is heated by a jacketed thermal fluid. The delicate cannabinoids flash-evaporate, travel a short radial distance, and condense on a specially heated internal condenser. This prevents a distillate "freeze" on the condenser, allowing it to flow smoothly into the collection vessel. Heavy, darkened waxes and tars continuously exit from the base as an easily removable residue, which may be re-distilled for further recovery.

How To Choose: Scaling Your Lab Sustainably

Begin with a 0.1m² or 2-inch glass system for R&D to map precise boiling fractions of your specific biomass input, as terroir and cultivar affect terpene and cannabinoid profiles. Transitioning to production requires evaluating feed processing rate in liters per hour and vapor load capacity. The critical decision is condenser temperature control; a hot condenser is mandatory for high-purity, solidifying THC/CBD distillates. Opt for a fully-jacketed body, not just traced lines, to eliminate cold spots where heavy fractions could accumulate and degrade. Confirm the package includes a chemically resistant vacuum pump and roots blower combination capable of sustaining the 0.01 mbar range under process load with ethanol/water vapor ingress.

FAQ

1. Q: Do I still need a winterization step before running Wiped Film?
   A: The major advantage is operational efficiency; our WFD system can process unwintered crude directly, saving 24-48 hours of processing time and up to 15% yield loss from filter media absorption. It completely bypasses traditional winterization for terpenes and cannabinoids.

2. Q: How is this different from a simple "short path" kettle?
   A: A kettle is a batch process with a thick, static pool of oil heated for hours, causing degradation. Wiped Film is a continuous process with a dynamic, micron-thin film, heating the oil for seconds. This results in a lighter color, superior terpene preservation if desired, and significantly higher throughput.

3. Q: Can this unit run both ethanol crude and CO2 crude?
   A: Yes, it is solvent-agnostic. However, it’s most efficient after primary solvent recovery. Our system directly refines the decarboxylated or non-decarboxylated thick oil, regardless of the initial extraction solvent.

4. Q: What safety measures are included for volatile production?
   A: All wetted components are pressure-rated, the motor is C1D2-rated for hazardous environments, and the PLC monitors all critical temperatures and pressures. Optional LEL gas sensors and automated vapor management ensure safe, unattended operation.

5. Q: How do you prevent cannabinoid crystallization inside the condenser?
   A: Our precisely controlled internal "hot condenser" circuit is maintained at a set point (e.g., 60-80°C) that keeps the cannabinoid distillate in a free-flowing liquid state, eliminating the risk of sudden solidification that plagues unheated cold-trap designs.
