1. Dust escape – making it difficult to maintain a clean workshop. Fine powders such as milk powder, protein powder and fruit and vegetable powder create large dust clouds during manual handling and pouring. Solid beverage production workshops are typically required to maintain a Class 100,000 cleanliness standard, and dust escape directly challenges the stability of the clean environment. At the same time, dust settling on equipment surfaces and workshop corners creates conditions for microbial growth and cross‑contamination.
2. Material loss – hidden costs that accumulate continuously. Under traditional manual transfer methods, raw material loss from dust escape can be significant. For high‑value ingredients such as whey protein powder and probiotic powder, every gram of powder that drifts away represents a direct economic loss. The cumulative effect of this loss rate in large‑scale continuous production is a cost that cannot be ignored.
3. Manual intervention – a dual bottleneck for efficiency and quality. The speed of manual handling, weighing and feeding is limited by workers' physical strength and skill, making it difficult to match the continuous rhythm of modern production lines. More critically, quality fluctuations caused by manual operations – inaccurate feeding quantities, incorrect order, foreign matter contamination – are risks that are always difficult to eliminate completely.
4. Cross‑contamination – ongoing pressure for GMP compliance. When switching between different formulations and batches, if the transfer equipment is not thoroughly cleaned, residual material will directly contaminate the next batch. In GMP audits and factory inspections, inadequate equipment cleaning and poor dust control are common points for deduction.
The working principle of the Gaofu solid beverage vacuum conveyor can be summarised in one sentence: using air pressure difference to make material flow automatically through an enclosed pipeline.
When the vacuum pump starts, it continuously removes air from the conveying pipeline and the vacuum hopper, creating a negative pressure state inside the system that is lower than the outside atmospheric pressure. The powder material, together with outside air, is drawn into the suction nozzle, forming an air‑powder mixture that travels through the enclosed conveying pipe to the vacuum hopper.
Inside the hopper, the material is separated from the air by a high‑precision filter – air passes through the filter element and is exhausted, while the material is intercepted on the outside of the filter and settles to the bottom of the hopper under gravity. When the material accumulates to a preset level, the discharge valve opens automatically and the material falls into the receiving equipment. Each time the material is discharged, a compressed air pulse reverse‑cleaning device automatically blows the powder adhering to the filter surface, restoring the filter element's permeability.
The entire conveying process is automatically controlled by a PLC or HMI. Suction time and discharge time can be continuously adjusted. The operator simply presets the parameters on the control panel, and the system automatically completes the cycle of "suction – separation – discharge – reverse cleaning" without manual intervention.
The fully enclosed pipeline is the core carrier of this system. From entering the suction nozzle to reaching the receiving equipment, the material travels entirely inside an enclosed stainless steel pipeline, without contact with outside air, without contact with operators, and without exposure to the workshop environment. The inner wall of the pipeline is mirror‑polished, with no hygiene dead corners and minimal material residue.
1. Fully Enclosed Dust‑Free Conveying – Maintaining Clean Production Standards
The Gaofu vacuum conveyor uses a fully enclosed pipeline conveying structure. Raw materials are kept from contact with air and operators from storage to conveying. This design provides three assurances: first, it fundamentally eliminates dust escape, maintaining workshop cleanliness; second, it prevents foreign matter and moisture from entering the conveying system, avoiding material contamination and moisture‑induced caking; and third, it reduces product quality inspection risks, helping enterprises present a more convincing compliance record during GMP audits.
2. Automatic Continuous Operation – Significantly Reducing Labour Dependence
The Gaofu vacuum conveyor has a high degree of automation, requiring only 1‑2 attendants per production line. The built‑in intelligent control module automatically adjusts the feeding speed according to the production process timing, achieving continuous operation of "conveying – metering – feeding". Automated feeding efficiency is 3‑5 times that of manual operation, and the capacity of a single production line can be increased by over 30%. One system can replace the material transfer work of 3‑5 people, eliminating the need for manual handling, weighing and feeding, and effectively reducing labour costs.
3. Flexible Conveying Distance – Unrestricted Line Layout
The conveying distance of the Gaofu vacuum conveyor can be flexibly configured according to workshop layout. Conventional horizontal conveying distances range from 10 to 50 metres, and vertical lifts from 3 to 15 metres. The conveying capacity covers a wide range from 200 to 6,000 kg/hour. Pipelines can be routed along walls, ceilings or floors, without being constrained by workshop space, making the production line layout more compact and aesthetically pleasing.
4. Food‑Grade Stainless Steel – Compliant with GMP Hygiene Standards
All parts of the Gaofu vacuum conveyor that contact material – pipelines, hoppers, suction nozzles, discharge valves, etc. – are made of food‑grade stainless steel, with finely polished surfaces, no hygiene dead corners, and easy to clean. The equipment has no gaps or dead corners where material can accumulate, and surfaces are easy to inspect visually. The system design strictly follows food GMP standards and is suitable for industries with strict hygiene requirements, such as solid beverages, dairy products and health foods.
5. Pulse Reverse Cleaning Self‑Cleaning – Long‑Term Filter Stability
During operation of the vacuum conveyor, the filter surface gradually accumulates fine powder, increasing filtration resistance and reducing conveying efficiency. The Gaofu system is equipped with a compressed air pulse reverse‑cleaning device. Each time the material is discharged, a high‑pressure pulse of air is automatically injected into the filter element, shaking off the powder adhering to the surface. This automatic reverse‑cleaning mechanism ensures that the filter maintains high permeability at all times, without the need for frequent manual cleaning, and supports long‑term continuous stable operation of the equipment.
The Gaofu solid beverage vacuum conveyor is suitable for dust‑free enclosed transfer of the following powder materials:
Protein‑based solid beverages: whey protein powder, soy protein powder, collagen peptide powder, pea protein powder, etc;
Probiotic‑based solid beverages: probiotic powder, compound probiotic solid beverages, etc;
Fruit and vegetable powder solid beverages: fruit and vegetable powders, green juice powder, dietary fibre powder, matcha powder, etc;
Meal replacement powder solid beverages: meal replacement powder, nutritional shake powder, meal replacement shake powder, etc;
Milk powder and plant‑based powders: whole milk powder, skimmed milk powder, soy milk powder, coconut milk powder, oat powder, etc;
Other powdered food ingredients: coffee powder, sugar powder, starch, cocoa powder, seasoning powder, etc.
In specific application scenarios: Automatic feeding from raw material storage to the mixer – automatically conveying powder materials stored in silos to the mixer, replacing manual handling and pouring. Finished product transfer from the screening machine to the packing line – automatically conveying screened acceptable powder to the packing machine hopper, achieving seamless connection from screening to packing. Cross‑floor and cross‑workshop material conveying – through flexible combinations of vertical lifting and horizontal conveying, enabling automatic material flow between different floors and different workshops.
