What Is The Characteristics of Freeze-Drying Machines for Drying Royal Jelly?

Here are the characteristics of freeze - drying machines for drying royal jelly:

- Low - temperature drying:

Freeze - drying machines dry royal jelly at low temperatures, usually between - 50℃ and - 80℃. This helps to preserve the biological activity and nutritional components of royal jelly, such as proteins, vitamins, and enzymes, preventing them from being damaged by high temperatures.
 

- High - quality drying:

The freeze - drying process can remove water from royal jelly while maintaining its original shape and structure. The dried royal jelly has a high rehydration rate and can quickly restore its original state when dissolved in water.
 

- Good preservation:

Freeze - dried royal jelly has a low water content, usually less than 5%. This helps to prevent the growth of microorganisms and the oxidation of nutrients, prolonging the shelf life of royal jelly.
 

- Gentle drying:

The freeze - drying process is a gentle drying method that causes little damage to the active ingredients in royal jelly. It can avoid the loss of volatile substances and the degradation of active ingredients, ensuring the quality and efficacy of royal jelly.

- High efficiency:

Modern freeze - drying machines are equipped with advanced control systems and efficient refrigeration and vacuum systems, which can shorten the drying time and improve production efficiency.
