Overview

Pneumatic vacuum conveying equipment description: Pneumatic vacuum conveying equipment uses compressed air as a power source to generate negative pressure for conveying various materials. It does not require mechanical vacuum pumps and has the advantages of simple structure, small volume, maintenance free, low noise, easy control, elimination of material static electricity, and compliance with GMP requirements. The high vacuum generated by the vacuum generator eliminates the phenomenon of layering in the conveyed material, ensuring the uniformity of the mixed material composition. It is an automatic feeding device for equipment such as tablet press, mixer, filling machine, dry granulation machine, packaging machine, crusher, vibrating screen, and reaction kettle.

Pneumatic vacuum conveying equipmentProduct Introduction

The vacuum conveying equipment forms an airflow under vacuum, and the material being conveyed is instantly transported to another container through the suction hose or tube under the action of this airflow. Due to the fact that the material is always in a vacuum state during the conveying process, even if there is a leak in the conveying pipeline, the material will not leak into the surrounding environment.

In the transportation of powder particles in industries such as chemical, pharmaceutical, and food, vacuum feeders are highly favored due to their high efficiency, cleanliness, and leak free characteristics. But to select the appropriate equipment, it is necessary to first understand its core technical parameters. This article will break down the 7 key parameters of the vacuum feeding machine for everyone.

1. Processing capacity (throughput)

▶ Definition: The weight/volume of materials that can be transported per unit time directly determines production efficiency
▶ Unit: Common kg/h (weight) or m ³/h (volume), to be converted based on material density
▶ Selection reference: For example, in the food industry, equipment that can transport milk powder at a rate of 100-200kg per hour is more suitable for small-scale production lines; For continuous production in the pharmaceutical workshop, models with a capacity of over 300kg/h can be selected

2. Vacuum degree (suction pressure)

▶ Definition: The pressure value of the internal vacuum state of the equipment determines the suction capacity and material conveying height
▶ Unit: International unit Pa (pascal) or engineering unit mbar (millibar), 1mbar ≈ 100Pa
▶ Industry standard: It is generally recommended to have a vacuum degree of ≥ -80kPa (-800mbar), which can transport materials with a particle size of ≤ 5mm; Higher vacuum degree (-90~-98kPa) is required for viscous materials such as flour and starch

3. Material compatibility parameters

▶ Material type: Clearly define the characteristics of the conveyed material (such as powder, particles, fibers) to avoid material compatibility issues
▶ Particle size range: General equipment is allowed to transport particles with a diameter of ≤ 0.1~10mm, and superhard particles (such as metal powder) require customized design
▶ Temperature limit: For ordinary models, the temperature resistance should be ≤ 80 ℃. For high-temperature materials (such as plastic particles), a high-temperature resistant pump body should be selected, and it is recommended to use a cooling device

4. Equipment material

▶ Contact with materials: 304 stainless steel (for food/pharmaceutical use) is preferred, while 316L stainless steel is recommended for high cleanliness scenarios (such as injection production)
▶ Non contact parts: carbon steel or aluminum alloy, reducing costs and meeting structural strength requirements
▶ Sealing material: silicone/nitrile rubber, to avoid material residue and contamination, FDA certified material is safer

5. Power parameters

▶ Vacuum pump power: determines the stability of vacuum degree. Single stage pumps are suitable for small flow rates, while two-stage pumps have higher vacuum degree (-98kPa), with a power of generally 2.2~7.5kW
▶ Motor power: Drive the conveying impeller or screw, matching the conveying capacity. For example, the motor power of a 100kg/h model is about 0.75kW
▶ Energy consumption index: The no-load power is 30% lower than the operating power. It is recommended to pay attention to standby power consumption to reduce long-term usage costs

6. Installation and Dimensional Parameters

▶ Dimensions: Length, width, and height are generally 1000 × 800 × 1500mm (small) to 2000 × 1200 × 2000mm (large), and maintenance space needs to be reserved
▶ Installation method: Floor standing (commonly used) or suspended (space saving), matching the workshop floor height
▶ Interface size: Inlet/outlet pipe diameter (e.g. DN50~DN100), whether it is smoothly connected to the production pipeline

7. Auxiliary performance parameters

▶ Noise level: Operating noise ≤ 75dB (A), in compliance with industrial plant noise standards
▶ Power requirements: 380V/50Hz (three-phase power) or 220V/50Hz (single-phase power), voltage compatibility needs to be confirmed
▶ Control system: PLC automatic control or manual operation, supporting functions such as material moisture content detection and material level alarm

The above parameters collectively determine the conveying efficiency, stability, and applicable scenarios of the vacuum feeder. When selecting, it is recommended to first clarify the processing capacity and material characteristics, and then match the vacuum degree and material requirements. If necessary, contact the manufacturer to provide customized solutions. Reasonable parameter configuration can not only ensure production safety, but also reduce equipment maintenance costs
