Buying Guide for Dual-Hopper Packing Scales for Potting Mix

Nutrient soil double bucket packaging scale is an efficient and accurate quantitative packaging equipment, dedicated to the automatic weighing and packaging of nutrient soil, matrix soil, organic fertilizer and other loose materials, suitable for horticulture, agriculture and organic fertilizer production industry. The double bucket alternating working mode increases the packaging speed to 1.5-2 times that of the single bucket scale, significantly shortening the production cycle.

First, core functions and advantages

Dual bucket alternating weighing: When one bucket is packed, the other bucket can be weighed in advance to improve the packaging speed (usually up to 8-12 bags/minute).

High-precision weighing: Using high-precision sensors, the error is controlled within ±0.2%, to ensure that the weight of each bag is consistent.

High degree of automation: support automatic bag loading, bag clamping, filling, sealing (optional), reduce manual intervention.

Strong durability: The contact part adopts 304 stainless steel or carbon steel anti-corrosion treatment, suitable for wet and corrosive environment.

Second, choose key parameters

3. Applicable scenarios

Fertilizer production enterprises: for organic fertilizer, compound fertilizer, biological fertilizer and other granular or powdered fertilizer quantitative packaging.

Horticultural substrate production: suitable for the packaging of peat soil, coconut bran, perlite and other horticultural substrates.

Soil conditioner: Used for quantitative distribution of humic acid, biochar and other soil conditioner.

Agricultural cooperatives: To meet the needs of large-scale planting bases for standardized packaging of nutritious soil.

Iv. Price reference (Market conditions)

Type Configuration Price range for enterprises

Economic semi-automatic (manual bag) 30,000 ~ 60,000 yuan small processing plant/entrepreneurial

Standard automatic bag + double bucket weighing 60,000 ~ 120,000 yuan medium-sized fertilizer/substrate factory

High-end automatic (robot bag + sewing bag) 120,000 to 250,000 yuan large organic fertilizer production line

Five, how to judge whether it is cost-effective?

1. Calculate the cost of a single package

Example: a double bucket scale of 100,000 yuan, 10 bags per minute, 200 days of annual work → annual packaging volume ≈ 2.88 million bags, the cost of single package equipment ≈0.035 yuan, much lower than manual weighing (about 0.1~0.2 yuan/bag).

2. Key upgrade value

Improved accuracy (±0.5% → ±0.2%) can reduce raw material waste and save costs in the long run.

Automation (such as automatic bag loading) can reduce 2-3 workers and save labor costs of 100,000 + per year.

3. Avoid the low price trap

Devices priced at less than 30% of the market price may use poor quality sensors or motors with a high failure rate.

Six, precautions

⚠ moisture proof design: nutrient soil is easy to absorb moisture, to ensure that the scale body seal is good, to avoid moisture sensor failure.

⚠ After-sales service: Choose a local brand with maintenance points to avoid stopping production due to failure.

⚠ Contract details: Specify whether installation, training, warranty period (usually 1-2 years) is included.
