Description
When handling high-boiling, thermally sensitive, or readily oxidized chemicals, traditional distillation generally fails. Excessive heat, long residence durations, and excessive energy consumption lead to product deterioration and low yield. This issue is resolved by Industrial Short Path Distillation Equipment. This method guarantees gentle separation, maximum purity, and exceptional recovery rates by combining high vacuum, incredibly small molecular transit distance, and effective heat transfer.
Imagine separating a complex mixture without destroying delicate compounds - this equipment makes it possible.
short path distillation setup
A complete short-path (molecular) distillation system includes a feed unit, evaporator, external cold trap, discharge unit, heating unit, refrigeration unit, and vacuum unit. The selection of each component must be appropriately tailored to the properties of the separation material, process requirements, and the company's available resources to ensure the entire system meets operational requirements.

Advantages
1. Ease of Operation and Maintenance
The modular skid-mounted design simplifies installation. CIP cleaning, standard KF joints, and robust seals reduce downtime between production runs.
2. Magnetic seal guarantees reliable vacuum performance, eliminating material contamination.
3-1. Dual-pump system (rotary vane + diffusion) achieves ultra-high vacuum <1Pa.
3-2. The adjustable vacuum valve design allows for easy vacuum level adjustment during operation.
4. Unified control panel: vacuum gauge and scraper speed display, and operation in one place.
5. Insulation pipelines, ball valves, and feed tanks guarantee consistent, steady, and superior insulation performance.
6. The double cold trap design allows for effortless temperature control, enabling the effective capture of ultra-light components and residual solvents. Additionally, the dual sight glass design of the cold trap provides enhanced process visibility.
7. Heavy-duty bearing casters minimize vibration loads and mitigate the impact compounds generated during the movement of the distiller.

FAQ
Q1: Can molecular distillation separate two compounds with very close boiling points?
A1: It is challenging, but possible. For example, to raise the ethyl palmitate: palmitic acid ratio from 9:1 to 96% purity, about 10–20% of the material must be distilled out. Customers are encouraged to send samples for feasibility testing.
Q2: What is the molecular distillation process for biodiesel?
A2:
Using two-stage molecular distillation, yields range between 85%–90%.
With four stages, yields improve to 90%–95%.
With six stages, yields can reach 93%–96%.
Q3: Can the gear pump used in molecular distillation be purchased separately?
A3: Yes, it can. Please confirm:

Q4: What is the maximum size available for a wiped film evaporator?
A4: The largest system we currently manufacture is a 10 m² wiped film evaporator with a capacity of 400 L.
Q5: How is MCT oil extracted from coconut oil?
A5: The common industrial method includes hydrolysis, rectification, and esterification. The esterified MCT oil is then purified through molecular distillation for high-quality results.
