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, recently mainly exported to Southeast Asia. In domestic dryer technology today, the drying process consumes a large amount of heat energy. 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. Â 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. To obtain perfect joins, inside of the solder ring copper fitting and the outside of the copper pipe are cleaned using coarse steel wool, flux paste is applied, the pipe is then inserted into the fitting and heat applied from a portable propane torch until a ring of solder shows at the edges of the fitting. Sizes we have available are from 8mm to 54mm For EN1254-1 and 1/2" to 2" for ASME B16.22 ,solder ring Copper Fittings,presolder copper fittings,yorkshire copper fittings,pegler copper fittings,connex copper fittings solder ring copper fittings,presolder copper fittings,yorkshire copper fittings,pegler copper fittings,connex copper fittings Taizhou Runde Company , https://www.zjcopperfittings.com
The heat is transferred from the high temperature heat source to the wet material in various ways, vaporizes the surface of the material and escapes to 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.
