Abstract

The invention discloses a kind of Wood rapid-drying methods, it includes the following steps, log is put into drying chamber by the first step, and is evacuated after drying chamber is sealed, using the cold energy of LNG as low-temperature receiver, it exchanges heat with room temperature refrigerant, the temperature of room temperature refrigerant is made to be down to 78 DEG C, refrigerant is stored in storage tank and is passed through in the chuck of drying chamber, the temperature in drying chamber is made to be down to 50 DEG C hereinafter, and keeping 30min；Second step opens drying chamber, and log is radiated with microwave, and timber water content is made to reach fibre saturated point；Third walks, and takes out log and places no less than in 3h indoors, log moisture is made to carry out cutting operation again after reaching water balance point.This method can be with fast drying timber wood, and is cut after the drying so that the wrinkle that plank will not contract cracks.

Description

A kind of Wood rapid-drying method
Technical field：
The present invention relates to wood processing fields, are especially a kind of Wood rapid-drying method.
Background technology：
In process of production, the drying of wood time is very big by seasonal effect, especially exists for existing fence board and wood composite pallet Plum rain season, fresh timber contain a large amount of moisture, and the natural evaporation of moisture can cause timber drying shrinkage, cracking, bending change occur Shape, the defects of going mouldy, seriously affect the quality of timber-work, therefore timber must be forced before all kinds of woodworks are made It is dried, in the prior art, usually log is divided into after plank and is dried in dry kiln, but wet log is cut It is affected afterwards to post-production, and cutting efficiency is very low.
Invention content：
The technical problem to be solved by the invention is to provide a kind of weatherproof, the timber for accelerating dry log is fast Rapid-curing cutback drying method.
The technical solution of the present invention is to provide a kind of Wood rapid-drying method, it includes the following steps,
Log is put into drying chamber by the first step, and is evacuated after drying chamber is sealed, using the cold energy of LNG as low-temperature receiver, It exchanges heat with room temperature refrigerant, the temperature of room temperature refrigerant is made to be down to -78 DEG C, refrigerant is stored in storage tank and passes through the folder of drying chamber In set, the temperature in drying chamber is made to be down to -50 DEG C hereinafter, and keeping 30min；
Second step opens drying chamber, and log is radiated with microwave, and timber water content is made to reach fibre saturated point；
Third walks, and takes out log and places indoors and is no less than in 3h, make log moisture reach after water balance point again into Row cutting operation.
Using compared with prior art, the present invention has the following advantages after process above：It can be quick by the above method Desiccated wood, and cut after the drying so that the wrinkle that plank will not contract cracks.
Specific embodiment：
With regard to specific embodiment, the invention will be further described below：
A kind of Wood rapid-drying method, it is characterised in that：It includes the following steps,
Log is put into drying chamber by the first step, and is evacuated after drying chamber is sealed, using the cold energy of LNG as low-temperature receiver, It exchanges heat with room temperature refrigerant, the temperature of room temperature refrigerant is made to be down to -78 DEG C, refrigerant is stored in storage tank and passes through the folder of drying chamber In set, the temperature in drying chamber is made to be down to -50 DEG C hereinafter, and keeping 30min；
Second step opens drying chamber, and log is radiated with microwave, and timber water content is made to reach fibre saturated point；
Third walks, and takes out log and places indoors and is no less than in 3h, make log moisture reach after water balance point again into Row cutting operation.
Can be with fast drying timber wood by the above method, and cut after the drying so that plank will not contracting wrinkle open It splits.

Claims (1)
