This invention discloses a method for the biological drying of sludge, comprising the following steps: baking biomass materials, mixing the resulting baked product with sludge, biochar materials, and a conditioner for biological drying, thereby completing the sludge drying process. In this invention, by biologically drying the mixture of baked product, sludge, biochar materials, and conditioner, not only can the self-generated heat within the system be used to effectively dewater the sludge in a very short time, but the bioavailability of the microbial carbon source can also be improved, effectively reducing the generation of polluting gases. This method can effectively reduce the emission of polluting gases while achieving rapid dewatering. It has advantages such as simple process, low treatment cost, low energy consumption, high drying efficiency, good dewatering effect, low polluting gas production, and low content of toxic and harmful components in the dried product. It can solve the problems of biomass resource waste and pollution, achieve sludge reduction and resource utilization, and has high returns and good application prospects.

This utility model relates to a grain processing and drying equipment. The structure includes: a dryer body, a processing cylinder, a rotary dispersing structure, and a sliding opening and closing mechanism. The top of the feed inlet of the dryer body is connected to the processing cylinder. Inside the processing cylinder, a rotary dispersing structure for dispersing materials is rotatably installed. A sliding opening and closing mechanism for controlling the material discharge is installed on the surface of the processing cylinder. By installing the rotary dispersing structure and using the sliding opening and closing mechanism to close the feed inlet of the processing cylinder, the grain is poured into the processing cylinder. A servo motor is then started, and the output shaft bevel gear of the servo motor contacts the bevel gear on the dispersing component, driving the upper and lower dispersing components to rotate in opposite directions, thus dispersing the grain and preventing clumps of grain from entering the dryer body and reducing drying efficiency.

This invention provides a method for controlling the introduction of fresh air into a washing machine and a washing machine in the field of washing machine technology. The method includes: during a drying cycle, acquiring the humidity of the external environment outside the washing drum and determining whether the humidity meets the conditions for introducing fresh air; if the humidity does not meet the conditions, controlling the fresh air introduction device to close and continuing the drying cycle; if the humidity meets the conditions, acquiring the temperature inside the washing drum and controlling the opening and closing of the fresh air introduction device based on the temperature inside the washing drum, and continuing the drying cycle. This invention introduces fresh air during the drying cycle to condense the hot and humid air inside the washing drum, further reducing the outlet air temperature of the washing drum and improving drying efficiency. Simultaneously, by detecting the ambient humidity during the introduction of fresh air, it avoids reducing drying efficiency due to insufficient humidity of the fresh air introduced into the washing drum.
