In the cross‑workshop and cross‑floor transfer of food powders, traditional methods have long faced three unavoidable problems:
Limited space layout – low manual handling efficiency. When production lines are distributed across different floors or workshops, manual material handling requires going up and down stairs and crossing workshops – consuming significant labour and extending material turnover time. For food processors with large daily throughput, the material transfer stage often becomes a bottleneck for the entire production line. Conveying distance reaches 5‑30 metres (horizontal conveying 10‑50 metres, vertical conveying 3‑15 metres) – effectively overcoming workshop layout constraints.
Dust emission – workshop environment fails to meet standards. During long‑distance transfer, materials must be transferred multiple times and exposed to the workshop environment multiple times. Each transfer is an opportunity for dust emission – fine powder escapes from equipment gaps and connection points into the workshop air, not only polluting the environment but also causing raw material loss. Gaofu's vacuum conveying system uses a fully enclosed negative‑pressure conveying principle – the entire transfer process takes place in enclosed piping.
Cross‑contamination risks – high risks during multi‑product changeovers. Food processors typically handle multiple product varieties – with frequent changeovers between different materials. In traditional transfer methods, material is exposed to the workshop environment multiple times – residue from the previous batch may contaminate the next batch, directly affecting product flavour consistency.
Gaofu's food‑grade vacuum conveying system achieves long‑distance, cross‑workshop enclosed transfer through its systematic technical design:
Vacuum pump provides sufficient negative pressure power. The vacuum pump evacuates the system, creating a vacuum state. Powdered material is drawn into the suction nozzle with outside air, forming an air‑material mixture that travels through the enclosed conveying pipe to the hopper, where air and material are separated. Conveying capacity covers 200 kg/h to 6,000 kg/h – meeting various needs from laboratory R&D to large‑scale production. Conveying distance reaches 1‑30 metres – flexibly configurable according to workshop layout.
Fully enclosed pipe conveying – completely eliminating dust emission. The entire conveying process takes place in a sealed system with no powder leakage. It completely eliminates material "spillage, leakage, emission, and drip" during feeding and conveying – effectively solving the dust emission problem. For easily airborne food powders such as powdered sugar and milk powder, this means dust has no opportunity to disperse at the transfer source.
Food‑grade stainless steel construction – meeting GMP standards. The equipment body and all material‑contact parts are made of food‑grade stainless steel (304/316L) – with smooth surfaces that are easy to clean. The entire machine design complies with GMP clean production standards for the food and pharmaceutical industries.
Pulse‑jet cleaning system – ensuring continuous stable operation. The equipment is equipped with a compressed air pulse‑jet cleaning system that blows back through the filters during each discharge cycle, dislodging powder adhering to the filter surface to ensure continuous and stable conveying. Conveying and discharge are automatically controlled by pneumatic three‑way valves, managed by a central control unit.
1. Breaking workshop layout constraints – enabling cross‑area material supply
Gaofu's vacuum conveying system allows flexible piping routing according to workshop layout – horizontal conveying reaches 10‑50 metres , and vertical conveying reaches 3‑15 metres. Whether cross‑floor, cross‑workshop, or navigating around equipment layouts, enclosed material conveying is achieved through piping. The equipment has a small footprint and can complete powder conveying in confined spaces regardless of distance.
2. Automated feeding – significantly improving efficiency
Automated feeding is 3‑5 times faster than manual operation, increasing single‑line capacity by over 30%. One system can replace 3‑5 workers – no manual handling, weighing, or dumping of ingredients – significantly reducing labour costs. Each production line requires only 1‑2 operators.
3. "Zero" residue in piping – reducing material loss
Fully enclosed pipe conveying means no spillage or waste during transfer. Material loss during conveying is minimal, and material properties are not compromised. For high‑value food ingredients such as powdered sugar and milk powder, this loss control accumulates into substantial long‑term savings.
4. Clean production – compliant with GMP standards
Fully enclosed pipe conveying is dust‑free and leak‑free, keeping the workshop clean. It effectively controls workshop dust concentration – meeting GMP clean production standards for the food and pharmaceutical industries. The equipment can be equipped with a dust explosion protection system (CNEX certified) and CIP cleaning interfaces.
Gaofu's food‑grade vacuum conveying system is widely suitable for enclosed conveying of various food powders and granular materials:
Powdered sugars: White sugar powder, rock sugar powder, icing sugar, etc.
Starches: Corn starch, potato starch, wheat starch, etc.
Dairy products: Milk powder, skimmed milk powder, whey powder, etc.
Bakery ingredients: Flour (high‑gluten, low‑gluten, all‑purpose), premix powders, breadcrumbs, etc.
Seasonings: Monosodium glutamate (MSG), chicken powder, salt, bay leaf powder, etc.
Food ingredients: Cocoa powder, yeast powder, premix powders, lactose, etc.
Long‑distance, cross‑workshop transfer of food powders requires not just "moving it and delivering it" but "delivering it cleanly and delivering it stably" – completing dust‑free transfer from one point to another in enclosed piping – without emission, contamination, or loss. Gaofu Machinery's food‑grade vacuum conveying system – with its fully enclosed negative‑pressure pipe conveying for long‑distance dust‑free transfer, food‑grade stainless steel construction for hygiene safety, and automated feeding for improved production efficiency – provides food processors with an automated, clean supporting solution from feeding to conveying.
