In the food industry, powdered materials are a common raw material, such as flour, milk powder, coffee powder, starch, sugar powder, yeast powder, grain powder, bran, potato snowflake flour, premix powder, yeast powder, bread crumbs, salt, monosodium glutamate, etc. These powdered materials require precise measurement and supply during the production process to ensure product quality and efficiency. However, traditional powder supply methods often have some issues.
High labour costs; traditional production methods require significant manual labour for repeated loading, unloading, transporting, and dispensing of raw materials. As labour costs rise, this inevitably increases labour costs;
Raw materials are prone to contamination, and hygiene and safety are not guaranteed; in traditional powder supply processes, during material dispensing and transportation, powdered materials are easily affected by external environmental factors, leading to contamination, and product hygiene and safety cannot be guaranteed. Batch consistency is unstable, affecting product uniformity; manual batching relies on worker discretion, leading to inconsistent batches and potential errors or omissions, thereby impacting product quality.
These issues result in unstable product quality, low production efficiency, and increased production costs. The powder supply system consists of a feeding system, storage system, screening system, drying system, iron removal system, metering system, and mixing system;
High degree of automation reduces labour costs.
The equipment takes up little space, reducing site costs.
Intelligent control reduces raw material waste and lowers energy consumption.
Pipeline sealed transportation, no dust spillage, clean production.
Pneumatic conveying is energy efficient, environmentally friendly, and does not easily damage the properties of the material.
The system achieves powder conveying through a closed-loop process of ‘negative pressure adsorption – gas-solid separation – clean exhaust,’ with the following specific steps:
1. Negative pressure generation: The negative pressure power unit (e.g., vacuum pump) is activated to create a stable negative pressure within the conveying pipes and separator;
2. Powder suction: The powder from the raw material receiving unit (e.g., flour after bag opening) is drawn into the conveying pipes by the pressure difference between atmospheric pressure and the pipe’s negative pressure, and flows along the pipes with the airflow (velocity 10–20 m/s, primarily dilute-phase conveying);
3. Gas-solid separation: The powder-laden airflow enters the cyclone separator, where the powder particles collide with the inner wall due to centrifugal force and fall downward, then discharged through a discharge valve into a temporary storage hopper or processing equipment;
4. Airflow purification: The separated airflow carries a small amount of fine powder into the filter, where it is filtered through filter bags (dust residue ≤ 0.1 mg/m³), and the clean air is discharged into the workshop or recirculated to the negative pressure source (energy-saving design);
5. Automatic start/stop: When the level sensor in the temporary storage hopper detects a ‘full’ signal, the control system closes the corresponding valve and stops the negative pressure source, completing one conveying cycle.
