Description

Technical Field

[0001] This utility model relates to the field of dryer technology, specifically a vacuum dryer with an exhaust valve. Background Technology

[0002] A dryer is a mechanical device that uses heat energy to reduce the moisture content of materials. It is used to dry objects. The dryer heats the material to vaporize and release the moisture, thereby obtaining solid materials with a specified moisture content. The purpose of drying is to meet the needs of material use or further processing. According to the operating pressure, dryers are divided into two categories: atmospheric pressure dryers and vacuum dryers. Based on the operating pressure, they can be divided into atmospheric pressure dryers and vacuum dryers.

[0003] Vacuum dryers are widely used in various industries such as chemical, pharmaceutical, and food processing to remove moisture or solvents from materials for drying, concentration, or crystallization. Traditional vacuum dryers generate large amounts of gas and vapor during operation, which need to be exhausted through an exhaust system to maintain the vacuum level and drying effect inside the machine. However, existing vacuum dryers often produce significant noise during exhaust, affecting the working environment and potentially damaging the hearing of operators. Furthermore, the exhaust system lacks flexible adjustment capabilities, making it impossible to precisely control the exhaust volume according to the different characteristics of the materials and the varying requirements of different drying stages. Therefore, a vacuum dryer with an exhaust valve is needed. Utility Model Content
