Our FAQs

Freeze drying is the most perfect method of preservation. Most botanical items (flowers, foliage, fruits, and vegetables) can be preserved with little change in shape, color or fragrance.

The botanical items are frozen and then placed under a deep vacuum. Under these conditions, moisture in them (in the form of ice crystals) will sublimate directly into water vapor, which then migrates into the condenser and is removed from the system. When sublimation is complete, the freeze dried botanicals can be removed.

There are several indicators of a load being dry from a freeze dryer. However, when ice quits forming in the condenser the load is done.

Botanique freeze dryers dry most types of flowers in 10 – 12 days. The answer depends upon many variables, such as type and quantity of product.

Yes! Removing the water too fast may cause blistering, shrinkage and shriveling.

Yes! The drying time is extended due to their density and water content.

Yes! Part of our training course delves into this area.

No! The quality of the end product is primarily determined by what you start with – “garbage in, garbage out.”

No. The machine requires only basic cleaning and an oil change after each load.

This depends on the size of the freeze dryer. Take the amperage requirements, listing in the specifications, to your electric company for a quotation.

Yes and No. It is a good idea to have someone check the machines each day and record temperature and vacuum readings, check the vacuum pump oil level, and run a defrost on the condenser, if necessary.

It takes approximately two minutes to record the daily information, and the defrost cycles take 30-45 minutes to complete.

We use Non-CFC refrigerants. They are environmentally safe and readily available throughout North America.

Freeze dryers need to be in a climatically controlled facility. An ideal temperature would be in the range of 70º-80º F and a relative humidity of 50% or less. Consider air conditioning, heating, and dehumidification when placing a freeze dryer in a garage. 

Yes! Botanique is very involved in both freeze drying research and pre- and post-treatment chemical research. All ongoing research information is made available to Botanique customers.
