How to choose a 40-kilogram nutrient soil powder packaging machine? How much is a set?

When choosing a 40-kilogram nutrient soil powder packaging machine, you should first consider your needs and then compare the configurations. The prices range from several thousand to several hundred thousand. The following are the key points of disassembly by Zhengzhou Hanke Machinery Equipment Co., Ltd. to help you avoid pitfalls:

First, ask yourself three questions (clarify your needs)

How many bags are wrapped in a day?

A small workshop bags several hundred bags every day: Choose a semi-automatic model (10,000-30,000), with manual bagging and machine weighing, offering high cost performance.

The factory's daily production exceeds 10,000 bags: it must be fully automated (100,000 +), with the entire process from bag supply, weighing to sealing being fully automated, saving labor.

What material is the packaging bag made of?

Woven bags/composite bags: Ordinary machines are fine. The sealing can be done by heat sealing or sewing.

Moisture-proof aluminum foil bag: It needs to have vacuum inflation function. The price is doubled (at least 30,000 yuan more).

What's special about nutrient soil?

Ordinary nutrient soil: Ordinary screw feeding + weighing sensor.

Humic acid/organic fertilizer: Choose a non-stick material design (screw + vibrating feeding), otherwise it is prone to clogging and the maintenance cost will be high.

Second, look at the three core features of the machine (Don't be fooled by fancy functions)

Weighing accuracy

The national standard is qualified within ±0.2%, but in actual use, stricter requirements are needed.

For example, if you package 40 kilograms of soil, an error of ±80 grams or less is considered excellent (a good machine can achieve ±50 grams), otherwise customers will complain.

Blanking speed

Ordinary model: 3-5 bags per minute (suitable for small factories).

High-speed model: 10-15 bags per minute (equipped with an automatic bag supply system, with an additional price of 50,000 yuan).

Dust-proof design

The nutrient soil has a large amount of dust. It is necessary to choose a fully enclosed box and negative pressure vacuum cleaner (plus 20,000 yuan), otherwise the motor will break down within half a year.

Iii. How is the price calculated? (Must-read for Bargaining

Basic model (semi-automatic) :

Spiral blanking + electronic scale + sewing machine: 15,000-30,000 yuan (most are from small factories in Hebei and Shandong, with poor after-sales service).

Brand machines (such as Nanheng and Jingke) : 30,000-50,000 yuan (2-year warranty, universal parts).

Fully automatic model:

Basic configuration: 100,000-150,000 yuan (including automatic bag supply, weighing and sealing).

High-end configuration: 200,000-300,000 yuan (with vacuum, detection and defective product removal functions).

Hidden costs:

Packaging bags: 0.5 yuan per ordinary woven bag, 1.5 yuan per moisture-proof bag, with a difference of 100,000 yuan per year.

Power consumption: Inverter models save 30% of electricity (10,000 yuan in electricity bills per year).

Iv. Guide to Avoiding Pitfalls (Personal Lessons Learned)

Don't believe in "all-purpose machines" :

A certain factory claimed to have "one machine covering all powder materials", but in the end, it covered perlite blocking materials and humic acid sticking materials, and had to be repaired four times in half a year.

On-site factory visit

It is required to watch the machine run continuously for 2 hours and observe the weighing stability (whether the fluctuation exceeds ±50 grams).

Check the brand of accessories: The "Mettler Toledo" sensor is 20,000 yuan more expensive than a no-name brand, but it won't break down for five years.

Contract trap

The contract of a certain factory states "one-year warranty", but the cost of spare parts is calculated separately (a new motor costs 8,000).

It must be clearly stated that "Vulnerable parts (such as spiral blades) are guaranteed for 3 months and can be replaced free of charge."

V. Reference to Real Cases

Case 1: In a certain flower base in Shandong Province, 500 bags are packed daily. A "Nanheng" semi-automatic machine (32,000 yuan) is selected. It has been in use for 3 years without major repairs, and the weighing error is ±60 grams.

Case 2: Jiangsu Organic Fertilizer Factory, with a daily packaging capacity of 20,000 bags, selects the "Jingke" fully automatic machine (180,000 bags), equipped with vacuum and rejection functions, saving 3 workers per year.

Case 3: A small factory in Hebei Province, lured by low prices, purchased a machine worth 12,000 yuan. The machine had uneven material cutting and had to be repaired five times within three months. Eventually, they spent an extra 20,000 yuan on a brand machine.

Summary: For small workshops, choose "Nanheng" semi-automatic (30,000 +), and for factories, choose "Jingke" fully automatic (150,000 +). The key points to consider are weighing accuracy and dust-proof design. Don't believe in low prices. After-sales service is more important than the machine itself!
