The invention discloses a high-speed centrifugal spray drying device and process. The high-speed centrifugal spray drying device comprises a centrifugal spray dryer, wherein an air distributor is arranged at the top end of the centrifugal spray dryer; a high-speed centrifugal atomizer is arranged on the inner wall at the top end of the centrifugal spray dryer; a heater is connected to the air distributor via a pipeline; the heater is provided with an air filter cover; an air feeder is arranged between the air filter cover and the heater; the high-speed centrifugal atomizer is connected with a trough via a pipeline; a feeding pump is arranged between the trough and the high-speed centrifugal atomizer; a gas outlet is formed in the lower half part of the centrifugal spray dryer and is connected with dust collectors via pipelines. The high-speed centrifugal spray drying device and process have the advantages of reasonable design and high drying speed; the products have good uniformity, flowability and solubility and high purity; adherence of heat sensitive materials to walls is not easily caused when the device and the process are used for processing the heat sensitive materials.
Description
technical field [0001] The invention relates to a high-speed centrifugal spray drying device and a drying process suitable for producing powdery, granular and other solid products from solution, emulsion, suspension and pasty liquid raw materials. Background technique [0002] In the fields of chemical industry, petrochemical industry, light industry, food, medicine, building materials, ceramics, etc., it is often necessary to dry some solutions, emulsions, suspensions, and pasty materials into dry powder. At present, spray dryers are generally used to achieve this. The technology adopted by the traditional spray dryer is to atomize the material first, and then dry it by heated air to dry it into powder. But it has the following disadvantages: 1. It will cause uneven or excessive heating of the product and affect the quality of the product. It is not suitable for the processing of heat-sensitive materials, and it is difficult to ensure the color and fragrance of heat-sensiti...
