Microwave drying of jujube is an efficient and environmentally friendly processing method, which takes advantage of the unique heating characteristics and drying mechanism of microwaves. When the polarity direction of the electric field continues to change, the polar molecules in the jujube will move at high speed and generate frictional heat, causing the surface and interior of the jujube to heat up at the same time to achieve the purpose of drying.

Microwave drying of jujube has the following advantages:

Fast drying speed: Since microwave heating directly heats materials, the drying speed is much faster than traditional methods.

Uniform heating and drying: Microwave heating has the characteristics of selective heating, which can achieve uniform heating and drying of jujube and ensure the quality of the product.

Preserve nutrients and flavor: Microwave drying is performed at low temperatures, which helps preserve the nutrients and traditional flavor of dates.

Energy saving: Microwave drying technology is more energy-saving than traditional methods.
