Abstract

The invention provides spray drying equipment for online control of powder moisture and a powder moisture control method, and the equipment comprises a drying device which comprises a cylinder body, wherein the cylinder body is internally provided with a sprayer, and the cylinder body is provided with a feed port, a first air inlet for introducing hot air flow and a first powder discharge port; amaterial supply device which comprises a material tank, a material conveying pipe connected to the material tank and the sprayer, and a material supply pump mounted on the material conveying pipe; a temperature sensor which is mounted in the first powder discharging opening; a first closed-loop controller which is connected to the feeding pump and the temperature sensor; a moisture sensor which ismounted in the cylinder body; and a second closed-loop controller which is connected to the first closed-loop controller and the moisture sensor. The problems that a traditional spray dryer needs tobe provided with professional technicians to detect the moisture of powder, consumed time is long, and moisture parameter information has large hysteresis quality are solved.

Description

technical field [0001] The invention relates to the technical field of spray dryers, in particular to a spray drying device for online control of powder moisture and a powder moisture control method. Background technique [0002] The spray dryer is a device that uses an atomizer to atomize a solution or a slurry-like liquid raw material, and then quickly dries it with hot air to obtain a dry powder product. For powder materials produced by traditional spray dryers, separate sampling and testing are required to obtain moisture-related parameters of the powder. On the one hand, the moisture-related parameter information will have a large lag; on the other hand, On the one hand, in the production process, it is also necessary to equip professional and technical personnel to regularly and repeatedly perform powder sampling and testing to ensure that the produced powder products meet the process requirements. Contents of the invention [0003] In order to overcome the shortcom...
