Description

A dust collector for producing rice protein powder

Technical Field

The utility model relates to a dust collector for producing rice protein powder belongs to dust collecting equipment technical field.

Background

The production process of the rice protein powder comprises the following steps: micronizing heavy metal rice to expose protein in rice endosperm; then, the rice protein and the winding embedding structure of other components are fully unfolded and separated by the high-temperature excessive liquefaction of the rice powder; meanwhile, the space structure of the rice protein is destroyed by high-temperature denaturation, the original compact sphere is changed into a loose chain structure, the binding sites of the heavy metal and the protein are fully exposed, and the heavy metal can be replaced from the protein by a food processing aid with stronger affinity with the heavy metal, so that the rice protein powder meeting the national standard is obtained. The generated dust is subjected to pulse dust removal and centralized dust removal treatment, so that the influence on the air environment is small.

At present, chinese patent with patent number CN207871755U discloses a high-efficient dust remover for albumen powder recovery, including dust cover, the clean room, the ash bucket, screw conveyer, the unloading valve, ash bag and clean gas channel, dust cover sets up in the clean room top, the ash bucket sets up in the clean room below, screw conveyer sets up in the ash bucket below, the ash bag passes through the unloading valve and sets up in the screw conveyer below, clean gas channel and clean room intercommunication, dust cover is equipped with the air inlet, clean gas channel is equipped with the gas outlet. When the dust removing device is used, dust-containing gas is sucked into the dust removing chamber, dust is adsorbed onto the filter bag in the dust removing chamber and enters the dust bag through the spiral conveyor and the dust discharging valve, and the processed clean gas is discharged from the gas outlet.

Generally, after the bag type dust collector is used for a period of time, the filter bag needs to be cleaned; the common cleaning means are: gas deashing, mechanical rapping deashing and manual rapping. However, a layer of dust formed on the surface of the filter bag after the filter bag is used for the first period of time is an initial layer, the initial layer becomes a main filter layer of the filter bag in the later movement process, and the filter bag with larger meshes can obtain higher filtering effect by virtue of the effect of the initial layer. If the primary layer is also removed during the cleaning of the filter bag, the filtration efficiency may be reduced when the filter bag is re-activated compared to before cleaning. The gas ash removal is that high-pressure gas is utilized to blow back the filter bag, because the high-pressure gas is usually compressed into small-beam airflow, the place directly blown by the airflow is difficult to leave an initial layer, and the small-beam airflow is difficult to clean all over the filter bag completely and without omission, and the filter bag is driven by the airflow in an inverted manner, so that the cleaning degree is uneven. The principle of mechanical rapping is the same as that of manual rapping, dust is shaken off by vibration, and the problem of uneven force application is solved, and meanwhile, whether the initial layer is well reserved or not is difficult to control.
