The invention discloses a sludge fragmentation-type drying device. The sludge fragmentation-type drying device comprises a transverse drying main cylinder, a frame for positioning the drying main cylinder and a rotor main shaft. One end of the drying main cylinder is provided with a feeding end and the other end is provided with a discharge end. The drying main cylinder can rotate relatively to the feeding end and the discharge end. The top of the feeding end is provided with a heat flue gas inlet and the top of the discharge end is provided with a wet flue gas outlet. The rotor main shaft is arranged in the drying main cylinder. The frame is provided with a bearing pedestal for positioning the rotor main shaft. The frame is provided with a main shaft driving motor for driving the rotor main shaft to rotate and a main cylinder driving motor for driving the drying main cylinder to rotate. Rotation directions of the rotor main shaft and the drying main cylinder are opposite. The rotor main shaft is provided with multiple stirring pushing rods. The sludge fragmentation-type drying device can effectively dry high-water content sludge, has a continuous and stable drying process, has high drying efficiency, has high integral drying uniformity and has good drying effects.

The invention provides a tunnel type fruit and vegetable drying chamber and a fruit and vegetable drying method in the technical field of drying. The tunnel type fruit and vegetable drying chamber comprises a drying chamber arranged on a base, wherein driving mechanisms used for driving a drying vehicle to enter and come out of the drying chamber are arranged on the base; the drying chamber comprises an outer box body and an inner box body; a circulating air duct is reserved between the outer box body and the inner box body; a plurality of circulating fans are arranged in the positions, at the top of the inner box body, inside the circulating air duct; heaters are arranged corresponding to the circulating fans; a plurality of circulating air holes are formed in the side wall of the inner box body; an air supplementation pipe is arranged on the inner box body to communicate with the external air; an air supplementation valve is arranged on the air supplementation pipe; a wet air discharge device is further arranged on the inner box body or the outer box body; the integral driving mechanisms are positioned inside the drying chamber; and openable and closable doors are arranged at the two ends of the drying chamber. According to the tunnel type fruit and vegetable drying chamber, the thermal loss is low, energy is saved, the fruit and vegetable drying degree is uniform, and the quality of dried fruits and vegetables is good.

The invention relates to the field of wood storage, and discloses a wood drying method. The method comprises the following steps of a, placing wood into liquid to be stewed, b, burying the stewed wood into high-temperature sand, c, taking out the wood from the sand and placing the wood into a heating furnace to be heated and dried under a vacuum condition, d, taking out the wood from the heating furnace and placing the wood outdoors to be naturally air-dried, and e, immersing the wood into liquid wax to form a wax film on the surface of the wood. Different from an existing drying method, the wood is dried through the high-temperature sand before being heated and dried, water is absorbed more evenly and mildly, and the drying degree in the wood is made more even, so that the fracturing phenomenon on the surface of the wood is effectively prevented, and material waste is avoided.
