Vacuum Dryer Technology in China Reverses the Export Situation of Equipment

The progress of vacuum dryer technology will reverse the current domestic export situation of drying equipment. China's vacuum dryer equipment export volume is less than 5% of the total, the export market scale has not yet been shaped, has been mainly exported to Southeast Asia.

In domestic dryer technology today, the drying process requires large amounts of thermal energy. In order to save energy, some high moisture content materials, suspensions or solutions containing solid materials are generally first mechanically dehydrated or heated to vaporize, and then dried in a desiccator. To get a dry solid. Here, Changzhou vacuum dryer manufacturers told everyone about the working principle of the vacuum dryer: During the drying process, the heat and mass (moisture content) transfer must be completed at the same time to ensure that the moisture partial pressure (concentration) of the surface moisture of the material is higher than the external. The moisture partial pressure of steam in the space ensures that the temperature of the heat source is higher than the temperature of the material.

The heat is transferred from the high temperature heat source to the wet material in various ways, vaporizes the surface of the material and disperses into the external space, so that the difference in moisture content occurs on the surface and inside of the material. The internal moisture spreads to the surface and vaporizes, so that the moisture content of the material is continuously reduced, and the overall drying of the material is gradually completed.

It is predicted that with the development of technology, the proportion of China's export vacuum dryer equipment in total output will increase from 5% to 10% in the next few years, and the export market will also expand to Europe and the United States. Gradually shorten the gap between the domestic large-scale vacuum dryer equipment manufacturing and the international level.

Warp Knitting Bearing And Bush

Warp Knitting Machine is a type of textile machine that is used to produce knitted fabrics. The machine uses warp yarns that are fed into the machine and are then interlocked to create a fabric. The machine consists of a series of needles that are arranged in a flat bed. The needles are moved up and down by a cam system, which allows the yarns to be interlocked.

The bearings and bushes used in warp knitting machines are critical components that ensure the smooth operation of the machine. These components are used to support the moving parts of the machine and to reduce friction between the parts.

The bearings used in warp knitting machines are typically ball bearings or roller bearings. These bearings are designed to support the rotating shafts and other moving parts of the machine. They are made from high-quality materials such as steel or ceramic and are designed to withstand the high stresses and temperatures that are generated during the operation of the machine.

The bushes used in warp knitting machines are typically made from bronze or brass. These bushes are used to support the moving parts of the machine and to reduce friction between the parts. They are designed to be self-lubricating, which helps to reduce wear and extend the life of the machine.

Overall, the bearings and bushes used in warp knitting machines are critical components that ensure the smooth operation of the machine. These components are designed to withstand the high stresses and temperatures that are generated during the operation of the machine, and they are made from high-quality materials to ensure their durability and reliability.
