How to choose a powder packaging scale for a microbial agent factory? How much is the price?

In the production of microbial agents (powders), when purchasing powder packaging scales, special attention should be paid to the material properties (such as fluidity, easy to raise dust, and possible corrosiveness) and packaging accuracy requirements. The following is the purchasing guide for microbial agent factories provided by Zhengzhou Hanke Machinery, covering equipment selection, price range and key points to note.

I. Key Points for Selecting Microbial Agent Powder Packaging Scales

1. Material property adaptation

Poor fluidity: The powder of the bacterial agent may adhere and form lumps. A forced feeding method (such as double helix, vibrating feeding + arch-breaking device) should be selected.

Prone to dust: Sealed design is required (negative pressure dust collection interface) + explosion-proof motor (if containing organic dust).

Corrosiveness: The contact parts should be made of 316 stainless steel or anti-corrosion coating (if some bacterial agents contain acidic carriers).

2. Packaging specifications and production capacity

Single bag weight: Commonly 5kg to 25kg per bag (higher precision is required for small packages).

Hourly production demand: Semi-automatic (manual bagging) : 180-600 bags per hour; Fully automatic (automatic bag loading + bag sewing) : 300 to 600 bags per hour

3. Key configuration requirements

Component | Recommended Configuration | Function

Load cell | High precision (±0.1% to 0.2%) | Ensures accurate proportioning of bacterial agents

Feeding system | Double helix + vibration arch breaking | Prevents powder bridging and caking

Dust removal system | Pulse dust removal + negative pressure recovery | Reduces dust pollution and meets environmental protection requirements

Control system | PLC+ touch screen, formula storage | Convenient switching between different packaging specifications of bacterial agents

Material | 304/316 stainless steel (contact parts) | Anti-corrosion, extending equipment service life

Ii. Price Range and Influencing Factors of Powder Packaging Scales for Microbial Agents

Basic model (50,000-100,000 yuan) : Single scale bucket, semi-automatic model, suitable for small-scale production. Functions mainly include metering, bag picking and bag sewing, with sensor accuracy ±0.5%.

Mid-range model (100,000-200,000 yuan) : Dual weighing bins, fully automated model, with added dust removal and data recording functions, sensor accuracy ±0.2%, supporting multi-formula switching.

High-end model (over 200,000 yuan) : Explosion-proof type, modular design, integrating metal detection, weight re-inspection, and robot palletizing, suitable for aseptic workshops or export standards.

Price influencing factors:

Customized requirements: such as special materials (316L stainless steel), explosion-proof grade (Ex d II CT4), non-standard scale bucket volume, etc., will increase the cost by 10%-30%.

Brand premium: The prices of imported brands are usually 30% to 50% higher than those of domestic ones.

Iii. Purchasing Tips and Pitfalls Avoidance Guidelines for Powder Packaging Scales of Microbial Agents

Supplier screening

✅ Industry experience: Preferred manufacturers with packaging cases of microbial fertilizers/microbial agents.

✅ Test verification: It is required to test with actual bacterial powder (avoid false labeling of laboratory data).

✅ after-sales service: Confirm the warranty period (at least 1 year) for core components such as sensors and motors.

2. Key terms of the contract

Acceptance criteria: Clear precision.

Training support: Whether on-site training for operators is included.

Spare parts supply: Inventory and replacement costs of vulnerable parts.

When choosing a powder packaging scale for microbial agents, it is important to focus on anti-sticking, dust-proof and anti-corrosion properties. Domestic equipment offers high cost performance (100,000 to 300,000 yuan), while imported equipment is suitable for high-demand production lines (400,000 yuan +).
