Project Overview
We supplied an integrated 2 TPH food powder screening line for a food ingredient manufacturer. This system adopts Sanyuantang vibro sifter matched with a vacuum powder feeder, realizing fully enclosed dust-free feeding and sieving. It removes impurities and grades fine food powder, meeting food hygiene requirements while avoiding powder leakage and cross-contamination.
Customer Screening Challenges & Requirements
The customer processes fine food powder and needed a continuous screening system with 2 tonnes per hour throughput. Fine powder is prone to floating dust and easy cross-contamination during manual feeding. They required food-grade stainless steel construction, enclosed conveying, impurity removal, easy disassembly cleaning, and stable continuous operation.
Our Custom Solution Design
Our engineering team recommended this integrated solution combining vacuum feeding equipment and our stainless steel vibro sifter. Raw powder is transferred through vacuum suction directly into the vibro sifter without manual handling. The multi-deck food powder vibro sifter separates oversized impurities and classifies powder fractions in one pass. All material contact parts are stainless steel, complying with food sanitation standards. The whole enclosed system eliminates dust escape and improves workshop cleanliness.

Project Benefits
Dust-Free Vacuum Conveying
The vacuum feeder transports powder to the vibro sifter through sealed hoses. It eliminates manual dumping, controls floating dust and prevents product contamination.
Compact Integrated Layout
The vibro sifter and vacuum feeder form a compact skid-mounted system. It occupies small floor space and is easy to install inside existing food processing workshops.
Food-Grade Sanitary Design
SS304 contact surfaces and quick-release clamps allow fast disassembly and thorough cleaning, fully matching food production hygiene specifications.
Stable Continuous Screening
The vibro sifter provides efficient separation for fine powder. It screens out foreign contaminants and ensures consistent finished powder particle size for downstream production.
Pre-Shipment Inspection & Commissioning
Before delivery, we tested the vacuum feeding performance and vibro sifter screening performance. We inspected mesh tension, sealing condition and machine running stability. On-site, our technicians guided installation, pipeline connection and parameter adjustment to help the customer commission the whole food powder screening line.
Project Outcome
After commissioning, the 2 TPH food powder screening line runs steadily. The vacuum feeding + vibro sifter system achieves dust-free production. Impurities are effectively filtered out, and finished powder meets the customer’s particle size standard. The integrated system reduces labor input and improves production sanitation level.
Note: Actual throughput and screening result depend on powder bulk density, moisture and feeding stability. Material testing is available for custom configuration.
