This invention belongs to the field of heat pump system design and operation control technology. It proposes a positive and negative pressure heat pump drying system and its control method based on the entire material drying process. An air duct is located at the end of the drying chamber furthest from the heat pump dryer, and a material cart is located at the end closest to the heat pump dryer. A positive pressure fan is installed at the air inlet of the air duct, and a buffer zone is provided between the material cart and the air outlet of the air duct. A negative pressure fan is installed at the end of the drying chamber located at the end of the material cart furthest from the buffer zone. During system operation, the speeds of the positive and negative pressure fans are controlled according to the material placement density and moisture content. By controlling the speed of the positive pressure fan, the problem of materials being blown off by the circulating air in the later stages of drying can be avoided. Simultaneously, considering the moisture content to control the fan speed ensures the dehumidification capacity within the drying chamber.

The invention provides a mesotrione continuous drying device, and relates to the field of drying devices. The mesotrione continuous drying device comprises a circulating air feeder and further comprises a cyclone separation assembly, a multi-layer filtering assembly, a heating assembly and a continuous drying assembly, the circulating air feeder conveys air to the heating assembly, the heating assembly conveys hot air into the continuous drying assembly, the continuous drying assembly conveys materials into the cyclone separation assembly, and the cyclone separation assembly conveys the materials into the multi-layer filtering assembly. And then the air is led to the multi-layer filtering assembly until the circulating air feeder is connected again. According to the mesotrione continuous drying device, by arranging the multiple layers of filtering assemblies, the effect of separating mesotrione in dried air can be achieved, waste of raw materials is avoided, the dried air can be prevented from polluting the environment, by arranging the continuous drying assembly, mesotrione can be pumped away by circulating air and then separated through the cyclone separator, and the mesotrione can be continuously dried. And the effect of drying mesotrione in all directions can be achieved until the drying requirement is met.

The invention relates to the technical field of single-cone mixed drying machines, in particular to a single-cone mixed drying system and process for directly drying hot air. The effect of reducing heat loss is achieved by introducing hot air into the conical container to make direct contact with materials, heating is more uniform, the drying temperature in the conical container can be controlled by directly adjusting the temperature of the hot air, and the material drying requirements under different conditions are met. In addition, the device is further provided with a liquid drainage system, solid-liquid separation of materials in the working process is facilitated, the drying time is shortened, the drying efficiency is improved, two spiral nitrogen is blown into the conical container from the bottom of the conical container in the drying process, the materials make direct contact with the spiral nitrogen, material bonding is effectively prevented, pilling is not likely to happen, and material residues at the bottom of the conical container are reduced. The material loss is reduced.

The invention discloses a drying and grain distributing system based on a dynamic sorting technology, relates to the technical field of drying, and solves the problem that an existing grain drying machine is poor in grain drying effect. A grain drying and separating system adopting the dynamic sorting technology comprises a grain drying machine, an elevator is arranged on one side of the grain drying machine, a downward flowing pipe is connected to the middle of the rear end face of the elevator, and a grain dynamic sorting mechanism located in the grain drying machine is arranged on the outer side of the end of the bottom of the downward flowing pipe. The grain dynamic sorting mechanism comprises a grain separation layer, a plurality of flowing ports and distribution gates with the same number as the flowing ports, and the downward flowing pipe is communicated with the interior of the grain separation layer. According to the cereal drying device, continuous closed circulation of cereals can be achieved, so that evaporation of water and drying uniformity are promoted, efficient and uniform drying of the cereals is achieved through the technical scheme, and the high-quality requirements of modern agriculture for cereal storage and processing are met.

The utility model relates to the technical field of thermal paper production equipment, in particular to a thermal paper production coating heat treatment quick-drying device which comprises a base, a rectangular shell is fixedly connected to the top of the base, communicating holes are formed in the middle positions of the two ends of the rectangular shell, and a plurality of rectangular holes are evenly formed in the top of the rectangular shell. According to the thermal treatment device, the thermal treatment mechanisms are arranged at the top and the bottom in the rectangular shell, the position between the electric heater and the thermal sensitive paper is adjusted by starting the two air cylinders, the two moving plates move by starting the double-shaft motor, and the two moving plates drive the corresponding sliding blocks to move, so that the thermal sensitive paper is heated, and the thermal sensitive paper is heated. And the moving sliding block drives the multiple rotating holes to unfold or stretch, so that the distance between the multiple electric heaters is adjusted, then the heat treatment mechanism can meet the drying requirements for the thermal paper under different conditions, and the practicability of the thermal paper production coating heat treatment quick-drying device is improved.
