When a family-owned sugar repackaging business in Sri Lanka decided to replace manual weighing with automated sachet packing, they chose the Shuliy 200 model sugar packing machine . After 90 days of operation, daily output tripled, defect rate fell from 2.3% to 0.4%, and ROI was achieved 1.8 months ahead of projection. Below is the full delivery story.
Customer Background
Our customer runs a family-owned sugar repackaging business in Sri Lanka. Founded in 2008, the company buys bulk imported refined white sugar and repackages it into single-serve sachets of 5g, 8g, and 10g. Their main customers are tea stalls, mid-range hotels, and restaurant chains across the Western Province.
Sri Lanka’s strong tea culture — the country produces around 250,000 metric tons of tea per year — drives a steady demand for individual sugar sachets. The country’s tropical climate (75–85% relative humidity, 28–32 °C average) makes any sugar-handling equipment prone to caking and clumping, which was a key concern when selecting a new machine.
The Challenge Before the 200 Model
Before 2026, his operation relied on manual weighing scales and hand-sealing. Each 8-hour shift produced roughly 1,200 sachets with four workers. Three persistent problems pushed the owner to seek an automated solution:
- Inconsistent fill weight — manual weighing varied by ±0.5g, generating complaints from hotel clients about underweight sachets.
- High labor cost — four operators per shift, plus overtime during the wedding and festival seasons.
- Monsoon clumping — from May to September, ambient humidity caused sugar to clump inside the hopper, blocking the manual funnel twice a day.
The customer required a compact machine that could fit into a 6 m × 4 m packing room, run on local 220 V / 50 Hz power, switch between 5g, 8g, and 10g sachets without lengthy changeovers, and survive the local humidity.
Why Choose the Shuliy 200 Model Sugar Packing Machine?
After evaluating three suppliers, the customer selected the Shuliy 200 model. The full technical configuration is summarized below.

| Model | 200 series (sugar sachet / small granule) |
| Dimensions (L × W × H) | 45 × 55 × 148 cm |
| Voltage | 220 V / 50 Hz (110 V / 380 V customizable) |
| Power | 600 W |
| Weighing range | 0.5 g – 99.9 g |
| Weight error | ±0.2 g |
| Packing speed | 700 – 1,200 sachets / hour |

Five design points matched the Kelaniya operation:
- Compact 45 × 55 × 148 cm footprint — installed in the corner of the existing packing room without any renovation.
- 220 V / 50 Hz native — no step-down transformer required, saving roughly USD 280 in auxiliary equipment.
- ±0.2 g fill accuracy — eliminated the under-weight complaints; all hotel clients renewed contracts in Q1 2026.
- 8-minute sachet changeover — switching from 5g to 10g requires only a former swap and a recipe selection on the touch screen.
- 304 stainless steel contact parts — anti-corrosion surface that has been running through the 2026 monsoon season without caking.

What the Customer Says
“We have used the 200 model for over three months. The ±0.2 g accuracy solved our hotel client complaints, and the machine ran through the May–June monsoon without a single hopper blockage — that was our biggest worry before importing. Your Engineer Zhang helped us finish commissioning two days early, which let us start fulfilling Diwali-season orders ahead of our local competitors.”
