Multistage cyclic drying system used for feeding particle aureomycin

Abstract

The invention discloses a multistage cyclic drying system used for feeding particle aureomycin. The multistage cyclic drying system comprises a draft fan, a dust remover, a cyclone separator, a multistage drying mechanism and a preheater, wherein inlets and outlets of the parts are sequentially communicated through pipelines; the pipeline between the multistage drying mechanism and the preheater is a first pipeline; the first pipeline is provided with a pelletizer; a dust exhaust opening of the cyclone separator is provided with air seal machinery; an inlet of the air seal machinery is communicated with the dust exhaust opening of the cyclone separator through the pipeline; an outlet of the air seal machinery is provided with a three-way valve; the three-way valve comprises a first interface, a second interface and a third interface; the first interface and the outlet of the air seal machinery are communicated through the pipeline; the second interface and the multistage drying mechanism are communicated through the pipeline; and the third interface of the three-way valve is provided with a material collecting device. The multistage cyclic drying system can be used for realizing multistage cyclic drying of feeding particle aureomycin, is good in drying effect, and time-saving and labor-saving.

Description

technical field [0001] The invention belongs to the field of airflow drying equipment, and in particular relates to a multistage circulation drying system for feed granule aureomycin. Background technique [0002] Existing drying equipment for chlortetracycline for feed usually only has one-level drying treatment, and its performance is unstable. Due to the control of hot air temperature, the speed of feeding and the different properties of materials, the final semi-finished product may contain moisture. Exceeding the standard, the drying effect is not good, resulting in a low yield rate in industrial applications. At this time, it is necessary to lift the unqualified semi-finished products upstairs, and then put the bags into the dryer for heating to remove water, which is time-consuming and laborious. Contents of the invention [0003] In order to solve the problems in the prior art, the present invention provides a multi-stage circulation drying system for feed granule...
