The Shanghai Yetuo drying oven is an important laboratory and industrial equipment used for drying various materials. The origin of the drying oven can be traced back to the early human demand for humidity control and preservation of substances. Here are some key historical stages in the development of drying ovens:

1、 Early drying methods

1. Natural drying:

In ancient times, people relied on natural environmental conditions such as sunlight and wind to dry crops, medicinal herbs, and other items.

The natural drying method is simple and economical, but its efficiency is limited by weather and time.

2. Flame and smoke drying:

With the use of fire, people began to use flames and smoke to dry items. This method is faster than natural drying, but poor temperature and humidity control can easily lead to item damage.

2、 Industrial Revolution and Technological Progress

1. Steam drying technology:

During the Industrial Revolution, steam technology was widely applied. The steam drying oven utilizes the high temperature of steam for drying, greatly improving efficiency.

Steam drying oven has been applied in industries such as textile and food processing.

2. Electric heating drying oven:

In the late 19th and early 20th centuries, the widespread use of electricity made electric heating drying ovens possible.

Electric heating drying oven can generate heat through resistance heating elements and provide a more uniform and stable drying environment through temperature control.

3、 Modern drying technology

1. Vacuum drying oven:

In the mid-20th century, vacuum drying technology was developed. A vacuum drying oven is suitable for drying thermosensitive materials by reducing environmental pressure to evaporate moisture at low temperatures.

Vacuum drying ovens are widely used in fields such as medicine, food, and biological products.

2. Microwave drying technology:

Microwave drying technology uses microwave energy to directly heat the moisture in items, resulting in faster drying speed and lower energy consumption.

Microwave drying technology is gradually being applied in the food processing and chemical industries.

3. Infrared drying technology:

Infrared drying uses infrared radiation to directly heat the surface of objects, which has the characteristics of uniform heating and fast speed.

Infrared drying technology is widely used in industries such as coatings and textiles.

4、 Modern application of drying oven

1. Precision control and automation:

Modern drying ovens are equipped with precision temperature and humidity control systems and automation control technology, which can achieve the drying process.

The data recording and monitoring functions enhance the controllability and repeatability of the drying process.

summary

The development history of drying ovens reflects the continuous growth and technological progress of human demand for material drying treatment. From early natural drying to modern vacuum drying, microwave drying, and infrared drying, drying oven technology is constantly innovating and its application fields are becoming more and more extensive. Modern drying ovens not only improve drying efficiency, but also achieve temperature and humidity control, meeting the requirements of various industries for drying treatment.
