A device for measuring the thickness of the thin layer of heat and mass transfer on the surface of wood during the drying process

Abstract

The invention discloses equipment for measuring the thickness of a heat and mass transfer thin layer on the wood surface in the drying process. The equipment comprises a wood drying chamber, a first feeding device, a second feeding device and a measuring device, wherein the first feeding device, the second feeding device and the measuring device are arranged in the drying chamber, and the drying chamber is internally and horizontally provided with a bracket used for placing to-be-dried wood; the first feeding device is perpendicular to the second feeding device, the second feeding device is fixed at the front end of the first feeding device, and the first feeding device pushes the second feeding device to move horizontally in the longitudinal direction or horizontal direction of the dryingchamber. The equipment for measuring the thickness of the heat and mass transfer thin layer on the wood surface in the drying process has the advantages that the collected data volume is large, measured results are accurate, the precision is high, the heat and mass transfer thin layer in the drying process of wood is improved, data support is provided for the wood drying quality, and good theoretical guidance is provided for strengthening heat and moisture transfer on the wood surface and increasing the wood drying rate.

Description

technical field [0001] The invention relates to a device for wood drying treatment, in particular to a device for measuring the thickness of a thin layer of heat and mass transfer on the wood surface during the wood drying process, belonging to the field of wood thermal processing. Background technique [0002] Wood drying is an important link in the wood product processing process, and its energy consumption accounts for 40-70% of the wood product processing process. Improving wood drying efficiency and reducing drying energy consumption have become urgent problems in the wood processing industry. [0003] At present, in order to improve the drying rate of wood, the invention patent 201410424968.7 provides a treatment device for improving the drying rate of wood and a method for drying wood by using the device. The present invention discloses a pretreatment device and a treatment method for improving the drying rate of wood. The device includes a wood treatment chamber with...
