CIRCULAR ARC-SHAPED FURNACE CHAMBER FOR MICROWAVE FAST MOISTURE TESTER

摘要

A circular arc-shaped furnace chamber for microwave fast moisture tester is provided, and the furnace chamber comprises an upper super-face (1), a lower undersurface (2) and a side wall surface, and the side wall surface is composed by connecting/combining a flat/straight surface (3-1) and a curved surface (3-2); The flat/straight surface (3-1) is a plane, and the curved surface (3-2) is a circular arc surface. Through the method of integrating the radial/axial energy accumulation and plane reflection/diffusion, the furnace chamber forms a uniform, high field strength density microwave heating space region in the space region where the sample is placed, thus improving microwave heating efficiency. The furnace chamber is especially suitable for dealing with sheet sample or large area sample, and can accurately, efficiently test the moisture volatile content of the sample, and is helpful to reduce the test result deviation of the sample having excessively high or low water content, thus improving the efficiency of the entire moisture volatile test work. The furnace chamber can be widely used in the field of sample water content test/analysis.
