Industry Application

Hemp and CBD Processing

Extraction, winterization and distillation equipment for hemp processors, supplied as single machines or as a complete line.

Complete winterization system installed at a hemp processing plant

Industry Pain Points

  • Crude that is too waxy and too dark to distil cleanly
  • Extraction rooms where flammable solvent handling is restricted
  • Separate machines bought from separate suppliers that were never designed to work together
  • Yield and colour that change from batch to batch

What Buyers Need

  • A defined route from biomass to finished oil
  • Equipment that has been run and tested before it ships
  • Sizing that matches the daily biomass throughput, not a catalogue number
  • Installation and operator training once the machine lands

Solution Flow

How a project in this sector is taken from raw material to running equipment.

1

Extraction

Supercritical CO2 for a solvent-free crude, or cold ethanol at -75°C for high throughput.

2

Winterization

Chill, hold and filter to drop out the waxes and lipids, then recover the ethanol.

3

Distillation

Short path distillation under deep vacuum to separate and refine the fractions.

4

Laboratory control

Rotary evaporator, glass reactor and short path distiller for trials and QC.

Delivery Capability

Machines from 0.5L to 200L, with larger capacity customised on request. A supercritical CO2 machine generally takes about 60 workdays to produce.

Packing And Shipping

Plywood case. The machine is assembled and tested before packing, so what ships has already been run.

Installation And Support

Installation service and engineer training on site, with online video guidance from engineers afterwards.

FAQ

Questions From Hemp and CBD Buyers

Can you supply the whole line rather than single machines?
Yes. Better Industry supplies the counter flow extraction system, ultrasonic extraction system, low temperature extraction system, CO2 supercritical extractor with winterization, short path distillation and rotary evaporator, and can provide a customised turn-key solution covering process parameters, engineering design, equipment manufacturing and installation.
Which extraction route should we choose?
It depends on throughput and on the finished product. CO2 gives a solvent-free crude with no purge step; cold ethanol at -75°C handles higher biomass volumes and leaves much of the wax and chlorophyll in the material. Send your material and target capacity and both routes can be costed.
Can you test our biomass first?
Yes. An extraction test can be run with your raw material, and videos and pictures of the trial are sent to you.

Talk To An Engineer About Your Hemp and CBD Project

Send the raw material and the capacity you need per batch and the right line will be proposed with the process parameters behind it.

Send two things and a real specification comes back: the raw material you will process, and the production capacity you need per batch.
