Microwave heating drying principle and characteristics
Microwave heating technology is a new heating method that relies on microwaves oscillating at a frequency of 245,00 per second to penetrate materials and interact with polar molecules within the materials. When polar molecules (such as water molecules) absorb microwave energy, they change their original structure and move in the electric field at the same speed, causing frequent collisions and generating a large amount of frictional heat. As a result, different parts of material gain heat energy simultaneously and increase in temperature. Since the thermal effect of the medium under microwave radiation is an internal overall heating, which is theoretically referred to asgradientless heating", there is basically no heat conduction phenomenon inside the medium, therefore, microwaves can heat the medium quite evenly.
Microwave drying is a new technology developed on the basis of microwave theory, microwave technology, and microwave electronics. Microwave drying been widely applied in many fields.
Microwave drying has the following characteristics:
1. Fast drying speed and short drying time Conventional heating requires heating media and, and then enters the material, so it takes a long time to reach the required heating temperature. However, microwave heating involves the direct absorption of microwave energy by object, with a heating speed much higher than conventional heating methods. It only takes one-tenth to one-hundredth of the time of conventional methods to complete entire heating and drying process.
2. High product quality Due to the short heating time and the combination of non-thermal effects, microwave drying can better preserve color, aroma, and taste of food ingredients, with minimal destruction of nutrients. This is especially advantageous in special industries.
3. Uniform heating Conventional heating the surface of the material first, and then transfers the heat to the interior through heat conduction. In contrast, microwave heating allows the surface and interior of the to be heated simultaneously, ensuring uniform heating and avoiding the unevenness often seen in conventional heating and drying processes, thus improving product quality.
4. High thermal efficiency small equipment footprint Since microwave heating is an internal heating method, the heating equipment itself does not radiate heat, resulting in minimal heat loss and high thermal, reaching about 80%. Compared to conventional methods, it can save 30% to 50% of electricity. Additionally, microwave heating equipment is small, requiring less factory space compared to conventional heating and drying methods.
