Description

Technical Field

[0001] The utility model relates to the field of malt production equipment, in particular to a flow control system of a silo bottom valve used in the malt making industry. Background Art

[0002] In the malting industry, the main cleaning process of the malting production line is to remove stones, impurities, small particles, iron, color sorting and other cleaning processes from the barley stored in the silo to obtain qualified barley raw materials that meet the malting requirements. The accuracy of the cleaning flow control is directly related to the quality of the malting. A control valve is installed at the discharge port of the barley silo to control the flow of barley to ensure the normal operation of the cleaning equipment and the quality of malting. The traditional control method relies on manual adjustment, which is inefficient and has low cleaning quality, and it is difficult to meet the requirements of modern malting technology. Therefore, a device that can achieve automatic and precise control is needed. Utility Model Content
