Compared with other drying methods, the drying cost of microwave dryers is usually higher. Here are some factors that contribute to the higher cost of microwave dryers:

1. Initial investment cost: The microwave dryer equipment itself is usually more expensive. Compared with traditional hot air drying equipment, the purchase cost of a microwave dryer may be higher.

2. Energy consumption: Microwave dryers need to consume a lot of electricity to generate microwave radiation for heating, which may lead to higher energy consumption costs. The generation and maintenance of microwave radiation requires high-power microwave generators and related equipment.

3. Operation and maintenance costs: The operation and maintenance costs of microwave dryers are usually higher. Maintaining microwave generators, control systems and other related equipment requires specialized skills and regular maintenance, which can increase operating costs.

4. Professional knowledge and operating requirements: Operating a microwave dryer requires certain professional knowledge and technology. Operators need to understand the principles of microwave heating, equipment operation and safety requirements. This may require training and specialized personnel, further increasing labor costs.

Although the cost of a microwave dryer is higher, it also has some advantages, such as fast and uniform heating effect and protection of product quality. Therefore, in a specific application, drying needs, budget, product quality requirements, and available resources need to be considered to determine whether it is worth investing in a microwave dryer. For large-scale production and high-quality mango drying, a microwave dryer may be an option worth considering.
