Heavy hardwood microwave oil bath drying system and method

Abstract

The invention discloses a heavy hardwood microwave oil bath drying system. The heavy hardwood microwave oil bath drying system comprises an oil bath cabin, and an upper cover is installed at the top end of the oil bath cabin through hinges and provided with a discharge net communicating with the oil bath cabin; the two sides of the oil bath cabin are provided with microwave assemblies; the oil bath cabin is filled with heat conduction oil and communicates with a heating tank through an oil return pipeline and an oil discharge pipeline; the oil return pipeline is provided with a circulating pump circulating the heat conduction oil between the oil bath cabin and the heating tank; and the heating tank is internally provided with an electric heating pipe for heating the heat conduction oil. The invention further discloses a heavy hardwood microwave oil bath drying method. The heating tank conducts cyclic heating, the heating tank and the microwave assemblies conduct heating and temperaturerising on wood at the same time, it is achieved that the interior and exterior of the wood are simultaneously heated, the drying speed is high, less water on the surface of the wood is quickly lost,and the quality of the dried wood is improved.

Description

technical field [0001] The invention relates to the technical field of wood drying, in particular to a microwave oil bath drying system and method for heavy hard wood. Background technique [0002] Heavy hard wood is a hard material with high strength and toughness. It is a valuable and expensive wood. After the original wood is harvested, the wood contains a lot of water and needs to be dried before it can be put into use. Most of the wood drying systems commonly used at present adopt hot air drying. For example, in the patent of CN206073679U, wood is placed in a drying kiln, and hot air is blown into the drying kiln to dry the wood. However, there are still many problems in the drying process of wood. The air flow can only pass through the surface of the wood. Although the surface and shallow layer of the wood are well dried, the moisture inside the wood cannot evaporate, resulting in excessive internal stress of the wood. , the resulting wood is defective, seriously aff...
