Information on Master Products LIO 40 Freeze Dryer
LIO 40 by Master Products is a state-of-the-art professional freeze dryer designed for drying flowers, extractions and other food products such as mushrooms, fruits... Its controlled vacuum freeze-drying technology allows maximum preservation of the aromatic compounds and the natural appearance of the material, offering a final result of superior quality.
Made entirely of AISI 304 stainless steel, LIO 40 combines robustness, hygiene and precision. It is designed for laboratories, micro-producers, cannabis clubs or technical growers looking for a fast, homogeneous drying process without loss of quality. Also available in Alchimia's catalogue, the Master Products LIO 70 freeze dryer, with more capacity and more power
Drying technology: efficiency and purity
The Master Products LIO Freeze Drying system removes moisture through a low temperature sublimation process, in which the frozen water in the product changes directly from a solid to a gas state.
This prevents the degradation of terpenes and cannabinoids, keeping the aroma, flavour, colour and texture (flowers and hashish) intact.
The stainless steel chamber and its digital control allow precise adjustment of the temperature, pressure and duration of each cycle. This results in uniform, oxidation-free drying, ideal for products requiring pharmaceutical quality standards.
Main uses of the LIO 40
- Drying of fresh cannabis flowers, maintaining their original organoleptic profile.
- Post-processing of extractions (ice-o-lator, bubble hash) to remove moisture without heating the product.
- Preservation of natural terpenes, essential oils and plant resins.
- Processing of food, mushrooms or medicinal plants, thanks to its precise temperature and vacuum control.
Its compact size and working capacity make it ideal for research projects, micro-production or environments where quality and traceability rather than volume are required.
Two versions available: with oil pump or oil free scroll
LIO 40 can be configured with two types of vacuum pump, depending on the user's needs:
Version with oil pump:
- Offers higher vacuum power, which speeds up drying cycles and improves efficiency on high density products.
- It is the preferred choice for technical producers and laboratories that require maximum control over system pressure.
- It requires periodicmaintenance (overhaul and oil change), but guarantees superior performance in terms of vacuum and speed.
Scroll pump version (oil-free):
- Uses a dry scroll pump, which requires no lubricant and generates no waste.
- Quieter, cleaner and maintenance-free, ideal for environments where product purity is a priority.
- Its vacuum level is slightly lower than the oil version, but sufficient for most flower and extract drying applications.
- Perfect for laboratories or facilities where simplicity, cleanliness and low operational maintenance are required.
| Feature | LIO 40 with oil pump | LIO 40 with scroll pump (oil-free) |
|---|---|---|
| Vacuum pump type | Oil-lubricated rotary | Dry scroll, no oil lubrication or maintenance |
| Drying speed | Faster, ideal for dense or high volume products | Slightly slower, but with uniform results |
| Maintenance | Requires periodic monitoring and oil change | Virtually maintenance free |
| Risk of contamination | Possible if oil is not properly maintained | Nil, no risk of cross contamination |
| Operating noise | Moderate | Quieter |
| Energy consumption | Slightly higher due to internal friction | More energy efficient |
| Durability | High, with regular maintenance | Very high, with less mechanical wear |
| Recommended environment | Technical or professional production where power and speed are a priority | Laboratories, clean environments or purity-priority facilities |
| Ideal applications | Drying of dense flowers, hash or high volume extractions | Delicate and oil-sensitive flowers, resins or products |
| Key benefits | Maximum vacuum power, fast drying and greater process control | Maintenance free, oil-free, cleaner and quieter |
| Price | More economical initially | Slightly superior due to scroll technology |
