This utility model relates to the field of aggregate production technology, and in particular to an aggregate pretreatment device for an asphalt mixing plant. It includes a conveying channel, with a feed hopper mounted on the upper surface of one end of the conveying channel. A rotating shaft is horizontally rotatably mounted inside the conveying channel, and an auger blade is fixedly sleeved on the rotating shaft. A drive motor is fixedly mounted at one end of the conveying channel, and one end of the output shaft of the drive motor is fixedly connected to one end of the auger blade. A rectangular cover is mounted on the conveying channel, forming a cavity between the rectangular cover and the conveying channel. The rectangular cover is equipped with a drying component for supplying hot air into the conveying channel. This utility model utilizes multiple air inlets to evenly supply hot air into the cavity formed by the rectangular cover and the conveying channel. The hot air can fully contact the surface and interior of the aggregate as it tumbles, preventing the hot air from only acting on the surface layer of aggregate, thus ensuring uniform drying of the aggregate and guaranteeing its subsequent performance.

The utility model has the advantages of safety, reliability, high automation degree, strong practicability, smaller radial size, economy and environmental protection.

The utility model discloses a multifunctional stove, which relates to the technical field of stoves and comprises a stove component, a heating component and a warming component. The stove assembly comprises a stove body, a smoke exhaust pipe, a combustion cavity and a fire grate, and a fire hole communicated with the combustion cavity is formed in the stove body; the heating assembly comprises a plurality of sets of heating pieces, a sealing piece, a sealing cavity, a heat distribution piece, a sealing plate and an exhaust piece. The heating assembly comprises a heating piece, heat dissipation holes and a first valve plate. The sealing part is arranged to seal the combustion cavity, so that smoke in the combustion cavity can only be exhausted from the smoke exhaust pipe, the smoke is prevented from escaping to the outside, meanwhile, airflow is conveyed into the heating part located in the combustion cavity through the air exhaust part, the airflow is conveyed into the sealing cavity after being heated, the airflow is dispersed in the combustion cavity through the heat distribution part, hot air is evenly distributed, and the combustion efficiency is improved. According to the utility model, heated high-temperature airflow can be used for cooking and heating, and in the cooking or heating process, flue gas separation is realized, so that the flue gas is prevented from acting on food or clothes.

This invention discloses a cooking appliance and its cooking control method, as well as a computer-readable storage medium. The cooking appliance includes a pot body and a heating element. The pot body forms a cooking cavity, and the heating element heats the cooking cavity. The cooking control method includes the following steps: based on the working stage of the cooking appliance, entering a deactivation stage; controlling the treatment of the cooking cavity, the treatment including at least one of heating, vacuuming, and oxygen removal; controlling the working stage of the cooking appliance to enter the cooking stage. The technical solution of this invention aims to enable the cooking appliance to undergo deactivation treatment before steaming or boiling, preventing the food to be cooked from discoloring and turning yellow after high-temperature cooking, thereby improving the cooking effect and reliability of the cooking appliance.
