Problems solved by technology

[0004] The purpose of the present invention is to address the above problems in the prior art and provide a redwood dehumidification process based on the inhibition of cell activity. The redwood dehumidification process based on the inhibition of cell activity can shorten the drying time of redwood and has a good drying effect. The drying process of mahogany is difficult to dry, and the drying time is long, etc.

Embodiment Construction

[0028] The current steam drying in wood drying was used as a comparison, and the test objects were 10 purple elms purchased from Guangdong.

[0029] Steam drying includes spray steaming stage (preheating), drying stage, and humidity control stage (drying follow-up adjustment stage, not for comparison), and the time spent in spray steaming stage and drying stage is mainly compared.

[0030] As shown in Table 1 and Table 2.

[0031]

[0032] As shown in Table 1 and Table 2, the moisture content of wood obtained from 10 purple elms by the steam drying method is 8.2%-9.8%, and the time spent is 12 days (excluding the humidity-conditioning stage).

[0033] The test object of this mahogany dehumidification process based on the inhibition of cell activity is also 10 purple elms purchased from Guangdong, including the following steps:

[0034] a, pretreatment, remove the branches and leaves of the felled mahogany, and then rinse the mahogany surface with a high-pressure water gun ...

Abstract

The invention provides a rosewood dehumidifying process based on inhibition of cell activity, and belongs to the field of rosewood processing. The process comprises the steps of pretreatment, shock heating and shock cooling circulation pressurized dipping, drying by heating and heating dehumidification drying; and through combination of shock heating and shock cooling temperature change with tiba, the activity of secondary walls in cell walls of rosewood cells and pectic substances and celluloses in middle lamellas is destructed, and the expansion / shrinkage motion of the cell walls in subsequent cooling process is reduced. The process can shorten the rosewood drying time, and is excellent in drying effect.

Description

technical field [0001] The invention belongs to the field of mahogany processing and relates to a mahogany dehumidification process based on inhibiting cell activity. Background technique [0002] Mahogany, the collective name for high-end and precious furniture materials in China, originally refers to red hardwood, with many varieties; after the 1980s, the demand for mahogany furniture increased, and the industry urgently needed to be regulated. According to the standard, the standard of mahogany is: two families, five genera, eight types, and thirty three types. Because of its slow growth, hard material, and more than a few hundred years of growth period, many mahogany native to southern my country were felled as early as the Ming and Qing Dynasties. Today's mahogany is mostly produced in Southeast Asia, Africa, my country's Guangdong and Yunnan have cultivated and introduced cultivation. The difference between the heartwood and sapwood of the wood is obvious, the sapwood...
