Before each startup, first check if the pump oil in the vacuum pump is sufficient.2. Unscrew the drain valve and let the remaining water flow out. After draining, tighten the valve.3. Check if the con

The Shanghai Yetuo Experimental Freeze Drying Machine is manufactured using the principle of freeze-drying in a vacuum environment and is currently a relatively advanced equipment for material dehydra

With the development of society, people are paying more and more attention to their physical health. While strengthening exercise, there is an increasing demand for natural, safe, and nutritious food.

The freeze-drying principle of Shanghai Yetuo freeze-drying machine:Freeze drying technology is a special drying technique, and the basic principle of freeze drying technology is based on the three-ph

Freeze drying machine is a technology that uses the principle of sublimation for drying. It quickly freezes the dried substance at low temperature, and then in an appropriate vacuum environment, the f

1. Eutectic temperature (Te)When a solution reaches a certain temperature or temperature range, its liquid state and the components in the formed solid state are completely the same. At this time, the

The basic principle of freeze-drying is based on the three state changes of water. Water can exist in solid, liquid, and gas states, which can both be converted and coexist with each other. When water

The Shanghai Yetuo in-situ freeze-drying machine is used in fields such as medicine, pharmaceuticals, biological research, chemical engineering, and food. Items that have undergone freeze-drying treat

Vacuum freeze-drying needs to be carried out in a certain device, which is called a vacuum freeze-drying machine or a pilot freeze-drying machine, abbreviated as a freeze-drying machine.The Shanghai Y

The Shanghai Yetuo freeze-drying machine is suitable for materials that are sensitive to heat and prone to thermal deformation and denaturation. In the field of biology, there are drugs, vaccines, ser
