The difference between freeze-drying and drying of Cordyceps sinensis

 The lyophilization of Cordyceps sinensis is carried out in a low-temperature vacuum environment by a lyophilizer, so that the water inside the fresh Cordyceps sinensis is sublimated, thereby obtaining freeze-dried Cordyceps sinensis. The dried Cordyceps sinensis is the water that evaporates the fresh Cordyceps sinensis under the natural conditions under natural conditions. One is the emerging science and technology, one represents the traditional drying process, what is the difference between the freeze-dried Cordyceps sinensis and the dried Cordyceps sinensis? Specifically, there are the following points:

First, the environmental impact

   The environment of sun-dried Cordyceps sinensis has a great impact. When it is rainy, it is easy to reduce production and reduce income. It is easy to cause inconsistent drying quality of each batch of Cordyceps sinensis. Freeze-dried Cordyceps sinensis is freeze-dried by freeze dryer and is not affected by weather changes. The effect is the same.

Second, the temperature effect

   Drying Cordyceps sinensis is dry under high temperature, which leads to the loss of some nutrients and heat-sensitive substances in Cordyceps sinensis. Freeze-drying is dry at low temperature and can retain its nutrients and active ingredients to a great extent.

Third, shape size impact

   After drying, the Cordyceps sinensis tends to shrink and become smaller; the lyophilized Cordyceps sinensis uses the principle of physical sublimation, and freeze-drying only sublimates the water content inside, so the shape of Cordyceps sinensis is almost unchanged after lyophilization.

Fourth, the color effect

   The color of dried Cordyceps sinensis varies greatly; the color of freeze-dried Cordyceps sinensis remains unchanged (one here depends on the quality of the equipment of Cordyceps sinensis freeze-drying machine, but also the setting process of freeze-dried Cordyceps sinensis. Ningb Scientz Biotechnology Co., Ltd. In addition to the patented product of our company, the Cordyceps sinensis freeze-drying machine, we can provide the freeze-drying process developed by the senior Cordyceps sinensis to ensure the effect of lyophilization (this is not available to other freeze dryer manufacturers).
