The Hopper weighing Feeding machine uses a bag opener to open bags and then directly conveys them through pipelines to the fermentation liquid storage tank. The remaining small amount of leftover material is manually fed into the hopper scale and then conveyed to the fermentation liquid storage tank through the hopper weighing pipeline. The hopper scale is a hopper machine with weighing and measurement functions, consisting of a hopper machine, a screw conveyor discharge device, a butterfly valve and a weighing module.

The hopper scale uses Weighing modules for measurement and is installed on the hopper machine to weigh the discharging device and the hopper machine. It calculates the difference between the total amount of material in the hopper machine and the weight of the material in the reduced weighing tank. Based on the weight loss per unit time, it compares the actual feeding rate with the set feeding rate, thereby controlling the discharging device to ensure that the actual feeding rate always accurately conforms to the set value.

The weighing feeding machine is composed of a Roots blower, a gate valve, a rotary feeding device, a Venturi jet device, conveying pipelines, pipeline branch valves, a hopper scale, a dust removal device on the top of the silo, an electrical control system and related auxiliary Settings. When the system is in operation, the Roots blower is started to generate a high-pressure columnar air flow. This high-pressure columnar air flow passes through the Venturi jet pump, creating a negative pressure inside, which enables the material supplied by the rotary Feeder to be promptly sucked into the jet port of the Venturi jet pump. The materials are conveyed through the conveying pipeline to the hopper scale. Then, the top-of-bin dust collector installed on the top of the hopper scale separates the materials from the conveying air flow, and the remaining air flow is promptly discharged outdoors.
