Function of the fruit.
Freeze dryer
How does the freeze dryer work
The Fruitworks Freeze Dryer works fully automatically and individually adjusts its drying process to the food placed inside.
About precise Sensors does the device recognise how much residual moisture is still in the products. Based on these measured values, the freeze dryer decides independently, When individual programme cycles are completed can become.
This intelligent control saves Energy and precious time, as the drying process only runs for as long as is actually necessary. As soon as the process is finished, a new charge inserted faster become.
No time for a change? Not a problem, the dryer works until the completed process is confirmed by the operator. No immediate intervention required, and you can sleep soundly.
The Drying time depends on the model, the product and the product quantity:
- With the M model and S-model it is approximately between 16 and 28 hours.
- With the L-model The standard programme takes approximately between 30 and 48 hours.
When the food pre-frozen are (at least 24 hours at -20°C, can it pre-programmed used. In this mode, the freezing process is skipped, which significantly shortens the overall drying time.
If complete pre-freezing is not possible, the Standard programme to be used – here too, the device automatically adjusts the runtime to achieve optimal results.
A night drying is possible manually, should the goods be very thickly cut.
Technical process of freeze-drying
Freeze-drying (lyophilisation) is a gentle method for preserving food, in which water is removed without destroying the cell structure. The process takes place in several steps:
- Freezing:The foodstuffs are brought to very low temperatures (down to -50°). The water contained within them freezes into ice.
- Vacuum generationThen, in the drying chamber, a Vacuum is produced. The air pressure drops sharply, causing the physical properties of the water to change.
- SublimationUnder these conditions, the ice passes directly from a solid to a gaseous state – this process is called sublimation. The water leaves the product as water vapour without melting first.
- CondensationThe water vapour is captured on the inner wall of the vacuum chamber in the device and re-bound as ice there.
- Post-drying (desorption)In a final phase, the residual moisture is removed to ensure a very long shelf life and optimal consistency.
The result is lightweight, crispy and aromatic products that regain their original shape and taste when water is added.
How does the freeze-dryer's software work?
Our Fruit Works Freeze Dryer are designed to be simple to operate, fully automatic and at the same time maximally flexible. You select the appropriate programme depending on the food – the rest of the process runs automatically. In addition, the software is continuously developed and improved through free updates.
Standard programme
The standard program is the ideal all-round setting and is suitable for almost all products.
- Automatic control of temperature and drying time
- Uniform and safe drying process
- No complicated settings required
- Perfect for beginners and daily use.
Pre-wash cycle
The pre-frozen programme is available for products that have been pre-frozen for at least 24 hours at a minimum of −20 °C.
- significantly shorter drying time
- higher efficiency
- Ideal for larger quantities or frequent use
Beta Version – Pro Update
The Pro Update (Beta version) gives you expanded features for more control and customisation.
Features included:
- Standard programme
- Pre-wash cycle
- The ability to create and save your own programmes
This allows the freeze dryer to be optimally adapted to different foodstuffs and individual requirements.
Important notice regarding the beta version
The beta software is still in the testing phase.
It is not intended for continuous operation or productive use, but is solely for testing and familiarisation with new functions.
