Convective Dryer

Convection dryers use a fan to drive hot air flowing over the surface of materials, utilizing the principles of heat conduction and moisture evaporation to remove moisture from the materials. They are used for drying coatings and paper, and can adjust temperature and air speed to suit different material characteristics.
Selection
When selecting, consider the material form and thermal sensitivity to match the drying temperature range; determine equipment capacity based on production volume; pay attention to the heat source type (electric/steam) and energy consumption; check if the air duct design is uniform; and ensure compatibility with on-site space and exhaust conditions.

Constant temperature bath selection: circulation method and temperature control range.
This article on thermostatic bath selection primarily analyzes two core factors: circulation mode and temperature control range. The circulation mode is divided into natural convection and forced circulation, where the former is suitable for simple static experiments, while the latter offers higher precision and is better suited for multiple samples or integration with external devices.

What are the differences between a vacuum oven and a conventional oven?
The main difference between a vacuum oven and a conventional oven lies in their working pressure. Conventional ovens operate at atmospheric pressure, heating through air convection, making them suitable for routine drying tasks. In contrast, vacuum ovens are evacuated to low pressure to reduce air presence, primarily relying on thermal radiation for heat transfer. This makes them ideal for processing heat-sensitive, oxidation-prone materials or those requiring thorough drying.
