3 Stages Short Path Wiped Film Molecular Distillation Machine

Product Description:

The 3 Stages Short Path Wiped Film Molecular Distillation Machine is a continuous feeding & discharge distillation machine. It perform a stable vacuum condition, a perfect golden yellow Herbal oil, 30% more yield coefficient.

The machine assembles with Dehydration & Degassing Reactor, which will do the perfect pretreatment before distillation process.

The full jacketed pipelines designed in the machine are heated by an individual closed industrial heater. Magnetic drive transfer pumps between stages and the discharge gear pumps are all heat tracing ones. That will avoid any coking or block in long time running.

Vacuum pump units are made of industrial roots pump, rotary vane oil pump unit and diffusion pumps. The whole system is running in high vacuum 0.001mbr/ 0.1Pa.

1) *The process capacity data listed above are as specific process capacity for crude hemp oil.

2) For bigger process capacity machines are available also.


1) Why I see a different process capacity from other suppliers? Especially both of the equipment have same figure of evaporation area? 

Generally speaking, normal process capacity is depend on the evaporation area. Once the evaporation area is fixed, then the normal process capacity is also fixed.

Since different feeding material with different nature, there will be a specific process capacity.

Specific process capacity is usually smaller than normal. For example, specific process capacity of hemp oil should be half of the normal capacity due to the high viscosity.

Besides that, the heating temp. Setting or vacuum degree would affect the process capacity, the affect will be every slight, though.

2) What's the specific process capacity for this machine?

We have 4 models for different process capacity.

MMD-03-2, 3~6 L/HOUR (Specific Process Capacity, Suggested)

MMD-05-2, 8~12 L/HOUR (Specific Process Capacity, Suggested)

MMD-10-2, 25~40 L/HOUR (Specific Process Capacity, Suggested)

MMD-20-2, 80~100 L/HOUR (Specific Process Capacity, Suggested)

3) Is it a turnkey machine?

Yes! It is a turnkey machine come with all the supporting facilities such as heater, chiller and vacuum

4) 3 stages molecular distillation machine VS 2 stages one VS Single stage one?


5) Do you have after-sales service?

Yes! We provide 24-hour online support, video technical support and free spare parts for free.

Overseas field Installation, commissioning and training is also available.
