Microwave log-drying device

Abstract

The invention discloses a microwave log-drying device, which comprises a box body, a power machine, a control system and an electrical control cabinet. The inner top part of the box body is provided with a microwave generating source, the lower part of the microwave generating source is provided with a microwave acting cavity, the microwave acting cavity is internally provided with a plurality of rows of rollers in the vertical direction, and the rollers can rotate forwards and reversely. A power machine chamber is arranged under the rollers, and the power machine used for driving the rollers to rotate is arranged in the power machine chamber; and the upper side of the box body is provided with a fan, and an induced air port of the fan is communicated with the microwave acting cavity. Microwave energy is adopted to dry logs, the microwave log-drying device has the advantages of uniform heating and high efficiency, the thermal efficiency is high, power consumption can be minimized, and automated control can be realized easily. Since the logs can be rotated forwards and reversely, every side face of the logs can be heated uniformly, and good heating effects can be achieved.

Description

technical field [0001] The invention relates to an industrial microwave energy application technology, in particular to a microwave log drying equipment. Background technique [0002] Traditional drying uses thermal conduction drying such as steam or electric heating, which takes a long time to dry, consumes a lot of energy, and is difficult to control the temperature. For example, steam heating requires a series of equipment. The thermal inertia of electric heating is large, and the temperature is not easy to control. Electric heating often uses heating components such as electric heating wires. The local heating temperature may be too high and there are still heating dead spots in some areas, resulting in uneven heating. Contents of the invention [0003] Aiming at the problems and deficiencies existing in the existing wood drying equipment, the present invention provides a microwave round wood drying equipment with simple structure and good use effect.
