CE 130 Convection Drying Thermal Lab Equipment Teaching Equipment Didactic Equipment1. Product Introduction
1.1 Product Description
This product is a teaching experimental convection drying device, mainly used for researching and demonstrating the convection drying process of particulate solids. It is widely used in experimental teaching in food technology and other related majors. The device uses an airflow drying method. A corrosion-resistant plate containing the solid to be dried is placed in the drying channel. The fan speed is adjusted, and the air temperature is controlled by a heater. As the airflow passes over the solid surface, it heats the solid and carries away the released moisture. The drying channel has a transparent door for easy observation of the entire drying process. The device is equipped with an electronic scale to monitor the solid weight change in real time, and sensors collect air temperature, humidity, and wind speed parameters. All measurement data can be directly transmitted to a computer for further processing and analysis.
1.2 Product Features
1. The device includes four corrosion-resistant drying plates, allowing for simultaneous drying experiments on multiple solid samples.
2. The drying channel has a transparent door for easy real-time observation of the sample drying status.
3. The fan speed can be adjusted to meet different experimental conditions.
4. The heater power is adjustable, and a temperature limiter ensures a safe and controllable heating process.
5. A high-precision electronic scale accurately records the weight changes of samples during the drying process.
6. Equipped with temperature, humidity, and wind speed sensors to collect environmental parameters in real time.
7. Supports data acquisition via USB interface on Windows systems; the accompanying software displays various parameters in real time and supports data export.
