1.1 material
The tested material was Masson Pine mature timber, which was collected from Liuzhou, the Guangxi Zhuang Autonomous Region. According to the test requirements, the logs were processed into 50 m m and 65 m m thickness, 2 m length of the whole side board, put in the freezer for storage. During the test, the whole side saw is made of 45 mm and 60 thickness respectively.
Mm, with a smooth surface of 100, 200, 300 mm.

microwave drying equipment
1.2 test device
The test device is mainly composed of mass weighing system, temperature detection system, microwave heating system and data acquisition system. In order to avoid the influence of microwave field on the measurement system, the temperature sensor and mass sensor are wrapped in aluminum foil to shield the microwave field. The microwave oven used is a domestic Panasonic frequency conversion microwave oven. The microwave oven was reformed before the test to meet the requirements of real-time quality and temperature detection during the test.
1.3 test method
1.3.1 Temperature Determination Method The size (100 mm long, 100 mm wide, 45 mm high) and the initial moisture content are first measured with epoxy resin and aluminum foil.
