Freeze Dryer: Preserve Your Products Safely
Sep
Keeping products safe, fresh, and high-quality is crucial for labs, food businesses, and the cosmetic industry. A Freeze Dryer is one of the best tools for this. It removes water from materials using freezing and vacuum technology, preserving their shape, nutrients, taste, and quality.
At Caresource, we offer two excellent models: the Tabletop Freeze Dryer and the Pilot Freeze Dryer FD20/30S. Both are designed to make freeze drying simple, efficient, and reliable for any lab or small production setup.
What is a Freeze Dryer?
A Freeze Dryer, also called a lyophilizer, preserves products by freezing them and then removing water under vacuum. Unlike normal drying, freeze drying works at very low temperatures, which protects sensitive materials like medicines, food, and lab samples.
The result is lightweight, safe products ready for storage or transport. Caresource ensures our freeze dryers maintain high quality and reliability for all your needs.
How Does Freeze Drying Work?
Freeze drying works in three main steps:
- Freezing – The product is frozen to very low temperatures (–40°C or below).
- Primary Drying (Sublimation) – The vacuum changes ice directly into vapor, removing most of the water.
- Secondary Drying (Desorption) – Gentle heat removes any remaining moisture.
The result is a dry product that keeps its original color, shape, flavor, and nutrients. With Caresource freeze dryers, this process is safe, efficient, and consistent.
