A vertical blast dryer is a commonly used laboratory equipment that uses heat energy to evaporate water from the sample by introducing air into the drying oven through a blower, thereby drying the sample. This article will introduce the working principle of a vertical blast drying oven in detail.
The vertical blast drying oven is mainly composed of a box, a heater, a blower, a temperature controller and a humidity controller. Among them, the box is the main part of the drying oven, which is made of insulation material, which can maintain the temperature and humidity in the drying oven. The heater is the heart of the drying oven, which heats the air through an electric heating element and thus transfers heat to the sample. The blower is a device that introduces air into the drying oven, which can circulate the air in the drying oven to ensure that the sample can fully accept heat and water evaporation. The temperature controller and humidity controller are devices that control the temperature and humidity in the drying oven, and they can automatically adjust the working state of the drying oven according to the set parameters.
The working principle of a vertical blast drying oven is as follows: first, the sample to be dried is placed in the drying oven, and then the heater and blower are turned on. At this point, the blower introduces air into the drying oven and heats it through a heater, which increases the air temperature. When the hot air comes into contact with the sample, it evaporates the water and the water vapor from the hot air is expelled from the drying oven. This process continues in a continuous cycle until the water in the sample has completely evaporated. During this process, the temperature controller and humidity controller automatically adjust the temperature and humidity in the drying oven according to the set parameters to ensure that the sample can fully accept heat and water evaporation.
In conclusion, the vertical blast dryer is an efficient laboratory equipment that can quickly evaporate the water from the sample, and is suitable for all kinds of samples that need to be dried.
