Abstract

The invention discloses a log drying device which is especially used for drying logs of small diameters. The invention comprises a machine body (6) provided with an inner hollow cavity, a heating device (18a, 18b and 24) and a log-loading truck (22) used for holding logs to be dried. The heating device and the log-loading truck are arranged in the hollow cavity of the machine body (6). The heating device lead drying mediums in the hollow cavity of the machine body (6) to form convection so as to provide heat to the logs arranged on the log-loading truck. A vacuum venting outlet (8) connecting with a vacuumizing device is arranged on the machine body and is used for vacuumizing the hollow cavity of the machine body while logs are dried. The adoption of the log drying device of the invention can quickly dry logs in a lower temperature and guarantee non-crack on logs. The invention is especially suitable for drying logs which have a better ventilating capability and are apt to crimple as well as hard broadleaf logs with a bigger thickness.

Description

technical field [0001] The patent of the present invention relates to a wood drying device, in particular to a wood vacuum drying device. Background technique [0002] According to the resource situation in our country, for a long period of time in the future, the raw materials for the development of my country's forest industry products will be mainly fast-growing small-diameter wood and branch wood with a short rotation period of 5 to 10 years. The development and application in the field of solid wood furniture and decoration will be an effective way to refine and deep-process small-diameter timber and improve the comprehensive utilization rate and added value of small-diameter timber. [0003] Due to the improvement of housing and living conditions, people's demand for furniture is increasing. At the same time, due to the enhancement of environmental protection awareness and yearning for nature, more and more people hope that their living space can be closer to nature. S...
