Bamboo Fungus Powder Lyophilizer

The benefits of processing and application of bamboo fungus powder lyophilizer, and the vacuum freeze-drying process of bamboo fungus. Bamboo fungus is crisp, tender, refreshing, sweet, and delicious. It is known as the "Queen of Fungus". Moreover, it is rich in nutrients and has certain medicinal value. bacteria, etc.

However, the bamboo fungus has high water content and is perishable, which is not conducive to storage and transportation. It is processed into bamboo fungus powder by vacuum freeze-drying combined with ultra-fine pulverization, which can effectively prolong the shelf life and better retain the original nutritional components of bamboo fungus. At the same time, bamboo fungus powder can also be added to other foods. , to expand the application of bamboo fungus.

The process technology of food freeze-drying machine in the processing of bamboo fungus freeze-dried powder, and other vacuum freeze-drying stage processes are mainly as follows:

(1) Determination of pre-freezing process: through the determination of the eutectic point and eutectic point of bamboo fungus, it is determined that the eutectic point and eutectic point of bamboo fungus are -27°C and -24°C respectively; The effects of thickness, pre-freezing temperature and pre-freezing time on the drying rate of bamboo fungus. On the basis of a single factor, the orthogonal test was further used to determine the optimal process parameters for the pre-freezing of bamboo fungus: pre-freezing temperature -35 ℃, The pre-freezing time is 4h, and the thickness of the paving is 12mm.

(2) Determination of the vacuum freeze-drying process: According to the saturated vapor pressure table of the ice crystal surface at different temperatures, the working pressure range of the vacuum freeze-drying chamber is determined to be 10Pa-39.99Pa. On the basis of a single factor, an orthogonal test is carried out. The data is analyzed by range and variance, and the optimal sublimation process conditions are determined as follows: working pressure 30Pa, sublimation temperature 55°C, cold trap temperature -45°C; to further determine the analytical process parameters, it is also first determined by single factor test. Parameter range, after doing the orthogonal test, through the analysis of variance and multiple comparisons of test results, the optimal analytical process conditions are determined as follows: the working pressure is 25Pa, the analytical temperature is 65 °C, and the analytical time is 3.5h.

FAQ:

Q:What is the difference between freeze-dried bamboo fungus and traditional dried bamboo fungus?

A:The main difference between freeze-dried bamboo fungus and traditional dried bamboo fungus is the processing method and the quality of the final product. Freeze-dried bamboo fungus is processed at low temperatures, retaining more nutrients and original flavor, while traditional dried bamboo fungus is usually dried at high temperatures, which may cause some nutrient loss and changes in texture and taste.

 

Q:Will the nutritional value of freeze-dried bamboo fungus decrease?

A:The nutritional value of freeze-dried bamboo fungus usually does not decrease significantly. Since freeze-drying technology is carried out under low temperature and vacuum conditions, it maximizes the retention of nutrients such as protein, vitamins and minerals in bamboo fungus.
