During the freeze-drying process of the freeze dryer, the temperature pre-freezing of the liquid articles and the subsequent sublimation of the moisture in the solid matter need to control the temperature within a certain range of the process requirements, which requires the freeze dryer to have a certain precision of temperature regulation...
With the rapid development of modern technology, more and more freeze dryers have entered our work life, especially the in-situ freeze dryers have been favored by customers because of their excellent results. So what do you need to pay attention to when using the in-situ freeze dryer? Let's take a look at it together!...
Due to the high requirements of the biopharmaceutical manufacturing environment, it is necessary to ensure that the manufacturing environment is dry, vacuum and temperature is suitable. ...
Fish gelatin is a dried product of fresh surimi, ideal for high protein and low fat foods and easy to absorb and utilize. However, most traditional methods of cooking fish gelatin are firstly soaked by soaking, then sliced or cut into pieces and cooked together with other ingredients. The problem caused by this process is that the bacteria are easily attached due to water quality problems during the foaming process, and since the dried fish gelatin has very low hydrophilicity, even after foaming, it takes a long time to cook to make collagen. Protein denaturation, making the soup thick and rich in collagen. With the continuous development of freeze dryers, this problem has been solved in the application of jellyfish freeze-drying....
The medicinal freeze-drying machine is also called a pharmaceutical freeze-drying machine, and is characterized in that the products are generally completed in the whole process of pre-freezing, heat preservation and sublimation drying on a set of shelves in the same drying box. Since the same set of shelves has both refrigeration and heating, it is generally indirectly conducted by intermediate media. T...
