Five precautions for use in cryogenic freezers

When it comes to crushing, we pay more attention to the crushing of some common materials, such as Chinese medicine, chemicals, food, minerals, etc., but when crushed like PVC materials, high-toughness materials and temperature-sensitive materials, There are many problems, and the cryogenic freeze pulverizer is a good way to solve the crushing of these materials. Now the more common low-temperature means is to use liquid nitrogen for ultra-low temperature freezing. Because of the special properties of liquid nitrogen, it is easy to cause harm to the human body. Beijing Yanshan Zhengde Machinery Equipment Co., Ltd. puts forward several precautions on liquid ammonia freezing and crushing based on years of experience:

1. For heat sensitive materials and high toughness materials (such as plastics), the FDV ultrafine pulverizer can be equipped with liquid nitrogen tank for low temperature pulverization.

2. Liquid nitrogen is pulverized at a low temperature to match a liquid nitrogen container containing a liquid nitrogen pump.

3. When using, follow the steps below: a. The liquid nitrogen outlet is aligned with the feeding port to start the pulverizer; b. The liquid nitrogen control switch is turned on, and the liquid nitrogen flows into the pulverizing tank body, and then the feeding is performed.

4. When stopping, follow the steps below: a. Stop the power of the crusher after about half a minute to one minute after stopping the feeding; b. Turn off the liquid nitrogen control switch; c. Remove the liquid nitrogen tank for cleaning.

5. When cleaning, please wear thick gloves to prevent frostbite.

The above are some precautions in the use of the cryogenic freezer, hope to help you better use the crusher to better protect yourself.

Heat Meters

Heat meters are one kind of meters measuring the heat consumption. In order to save the energy and decrease the environment pollution, the heat meters are more and more popular for the modern buildings. Heat meters can realize centralized heating supply. Now with the rapid technology development, the heat meters also experience a fast way of growing up. Now the government of the world starts to pay much attention to the building remolding and new buildings heat meter installation. As the new type of energy calculation, the heat meters have the advantages of higher accuracy, energy saving and easy installation.

From the functions of the different types of heat meters, there are mechanical heat meters, digital heat meter,Ultrasonic Heat Meters, M-bus Heat Meters and also wireless heat meters. Our company, Berggruen Technology Co.,Ltd never stops the steps for further higher technology research and development. We are devoted to study the new technology in the world to make better quality heat meters.
