Abstract

A containing cavity is formed in a shell, a support is arranged in the containing cavity, a collecting pot is fixedly arranged on the support, a conical base is fixedly arranged at the bottom of the collecting pot, a rotating hole is formed in the conical base, a rotor is arranged in the collecting pot, and one end of the rotor penetrates through the rotating hole and is rotationally connected with the bottom of the containing cavity. The disc is fixedly arranged on the rotor, the air inlet mechanism is fixedly arranged in the collecting pot, the condensation mechanism is embedded in the shell and electrically connected with the air inlet mechanism, the cover plate is rotationally connected to the shell, and the atomizing nozzle is fixedly arranged on the cover plate and electrically connected with the air inlet mechanism. According to the continuous vacuum spray drying device provided by the invention, the collecting pot is driven to rotate through the rotor, so that liquid drops continuously roll while being dried, particles which are highly uniform in roundness and relatively compact are prepared, and the product quality is improved.

Description

technical field [0001] The invention relates to the technical field of drying equipment, and more specifically, to a continuous vacuum spray drying device. Background technique [0002] Spray dryer is a drying treatment equipment that processes liquid materials such as biology, medicine and food into powder materials through atomization and heating. The pasty material with moisture is sprayed into fine droplets in the hot air. During the falling process of the droplets, the water is evaporated into powder or granular products, so that two processes of spraying and drying can be completed in a single process at the same time. [0003] Existing spray dryers usually use high-temperature air and atomized concentrated liquid to enter the drying chamber through different nozzles, so that the high-temperature air can fully contact the atomized concentrated liquid, and then the water in the atomized concentrated liquid is heated and evaporated. The product is separated from the con...
