One-step pelletizer

Abstract

The invention discloses a one-step pelletizer, which comprises a frame, wherein a fluidized bed pelletizing chamber is arranged on the frame, the fluidized bed pelletizing chamber comprises a lower material bin and an upper pelletizing bin, an air inlet bin is arranged at the bottom of the material bin, an air flow distribution plate is arranged between the air inlet bin and the material bin, the air flow distribution plate comprises a plate body, a plurality of vent holes are formed on the plate body, an airflow tube is arranged on each vent hole, an auxiliary ring is formed on the circumference of the plate body, the interior of the auxiliary ring is a hollow cavity, a plurality of outlet holes are formed on the inner side wall of the auxiliary ring, and the outlet holes are communicated with the hollow cavity; and an air inlet pipe is arranged at the bottom end of the auxiliary ring. The one-step pelletizer of the invention can solve the shortcomings in the prior art, and in the interior of the fluidized bed pelletizing chamber, the pellets are uniform, the dead angle is reduced, and the pelletizing efficiency and quality are improved.

Description

technical field [0001] The invention relates to the field of medical machinery and equipment, in particular to a one-step granulator. Background technique [0002] The working principle of the one-step granulator: the powdery material is put into the closed container of the hopper, and due to the action of the hot air flow, the powder is suspended and circulated in a fluidized state to achieve uniform mixing. Powder, the powder is condensed into loose small particles. At the same time of granulation, due to the efficient drying of the hot air flow, the water is continuously evaporated, and the powder is continuously solidified. The process is repeated to form ideal, uniform microporous spherical particles. , complete the three processes of mixing, granulation and drying in one container. [0003] At present, we know that the existing one-step granulator has insufficient overall setting of the internal fluidized bed, and the internal wind field is uneven, which is mainly cau...

AI Technical Summary

Problems solved by technology

[0003] At present, we know that the existing one-step granulator has insufficient overall setting of the internal fluidized bed, and the internal wind field is uneven, which is mainly caused by the insufficient design of the internal differentiation plate, which leads to the fluidization of the material inside the machine 1. The granulation is not uniform, and it is easy to produce dead angles inside, which will cause bed collapse and dead bed phenomenon during granulation, which will seriously affect the quality and efficiency of granulation; therefore, the applicant based on the existing one-step granulator A further improvement is proposed above, and a one-step granulator is designed to meet the needs of the existing market
