The invention discloses a gluten-free powder and surface vacuum feeding system, which comprises a feeder body and a filter material body. The filter material body comprises a volute-shaped outer filter piece and an inner filter element, wherein the inner filter element is positioned in the outer filter piece, an outer airflow cavity is formed between the outer filter piece and the feeding machine body, an inner airflow cavity is formed between the outer filter piece and the inner filter element, and the outer airflow cavity is communicated with the inner airflow cavity. The invention relates to the technical field of pneumatic vacuum feeding and conveying, wherein a filter material body reciprocates up and down in a rotating state, and powder is separated from the filter material body efficiently under the centrifugal force and continuous vibration, so that dynamic desorption is realized. The filter material body adopts a volute-shaped outer filter piece and an inner filter core double-layer structure to carry out graded filtration, the outer filter piece and the feeder body form an outer airflow cavity, and the inner filter core and the outer filter piece form an inner airflow cavity. When the airflow is wrapped with powder, the filter screen of the outer filter cavity can pre-adsorb part of powder, so that the amount of powder entering the inner filter core is reduced, and the continuous negative pressure suction capacity is improved.

Description

Gluten-free powder dough kneading vacuum feeding system Technical Field The invention relates to the technical field of pneumatic vacuum feeding and conveying, in particular to a gluten-free powder and flour vacuum feeding system. Background In the production process of stretched noodles, dough kneading is one of key processes, and a pneumatic pipeline conveyor is generally adopted to convey powder to a dough kneading machine, and then the powder is mixed with water, additives and the like for stirring. In the prior art, the conveyor mainly relies on the negative pressure environment in the tank body, and utilizes the air pressure difference to suck powder into the tank, the powder is adsorbed on the surface of the filter element, after the adsorption is finished, the material on the filter element is blown off through positive pressure back blowing, and after the material is accumulated to a certain amount, a valve is opened to enable the powder to fall into the dough mixer.
