As a type of cordyceps processing equipment, the cordyceps freeze-drying machine has significant advantages compared to traditional processing methods, mainly reflected in the following aspects:
1、 Nutritional retention advantage
The cordyceps freeze-drying machine adopts low-temperature vacuum freeze-drying technology, which can effectively retain the thermosensitive nutrients in cordyceps:
1. Retention rate of over 98%: The freeze-drying process is carried out at low temperatures, avoiding the damage of heat sensitive components such as cordycepin (rapidly decomposed above 60 ℃), adenosine (significantly reduced above 80 ℃), and superoxide dismutase (inactive above 50 ℃) caused by high temperatures.
2. Complete active ingredients: able to fully retain cordycepin (mannitol), adenosine, amino acids, and trace elements, fully preserving the activity and effective nutritional components of cordyceps.
3. Low loss of volatile components: Low temperature drying reduces the loss of volatile components in substances, making it suitable for drying some chemical products, drugs, and food.
2、 Product quality advantage
Freeze drying technology can significantly improve the quality of cordyceps products:
1. Shape and color preservation: Fresh cordyceps is pre frozen at low temperatures to fix its cell structure, and after drying, it forms a porous structure with basically unchanged shape; Rapid freezing and vacuum dehydration inhibit the fading of cordycepin, retaining its natural pale golden color.
2. Good taste: The freeze-dried cordyceps has honeycomb like micropores inside, crispy and fluffy; After rehydration, the taste and morphology are close to over 90% of fresh cordyceps, and the aroma is rich.
3. Excellent rehydration performance: The freeze-dried cordyceps is loose and porous, and dissolves quickly after adding water, almost immediately restoring its original appearance.
3、 Processing efficiency and safety advantages
Cordyceps freeze-drying machine has outstanding performance in processing efficiency and safety:
1. Fast drying speed: Compared to traditional drying methods, vacuum freeze-drying technology can significantly shorten drying time and improve production efficiency.
2. Low risk of microbial contamination: The vacuum environment greatly inhibits the growth and reproduction of microorganisms, reducing the risk of contamination of medicinal materials during the drying process.
3. No chemical changes: There are only physical changes during the production process, no chemical changes, and no need to use any preservatives.
4. Safety and Environmental Protection: Avoiding the pollution of harmful gases generated by traditional coal-fired boiler drying on the quality of cordyceps.
4、 Storage and usability convenience
Freeze dried cordyceps has significant advantages in storage and use:
1. Long shelf life: Freeze dried cordyceps has a low water content (about 8%), low water activity, and cells are in a 'dormant state', which can be stored at room temperature for 3-5 years without preservatives.
2. Convenient storage and transportation: The freeze-dried cordyceps has a small volume and light weight, making it easy to store and transport.
3. Convenient to use: Fast rehydration speed (can be restored to fresh state after soaking in water for a few seconds), can be soaked as needed, and can also be opened and ready to eat.
4. No refrigeration required: Traditional high-temperature drying of cordyceps leaves about 15% residual moisture, so it is best to store it in refrigeration.
