Overview
Food production lines require strict hygiene standards and stable operational efficiency. Conveyor belt residue, oil stains and baked dirt are unavoidable during long-term bakery production. Traditional outsourcing and sandblasting cleaning methods often cause long downtime, equipment wear and high labor costs.
Suzhou Fangshiheng Precision Machinery Co., Ltd. provided a customized 500W automated laser cleaning system for Uni-President’s cake baking production line. This intelligent in-situ cleaning solution completely replaces traditional sandblasting outsourcing, greatly shortening maintenance time, improving food safety standards and extending conveyor equipment service life. This case study systematically introduces the project background, pain points, customized solutions and final actual benefits.
Customer Background
Uni-President Foods is a leading large-scale food and beverage manufacturing enterprise in China. Its automated cake production line runs continuously with high daily output. The baking conveyor chain plates will accumulate oil stains, burnt residues and organic dirt during long-term operation. To meet food safety regulations and ensure stable product quality, the production line must be cleaned regularly and thoroughly.
Traditional Cleaning Pain Points & Challenges
Before cooperating with Fangshiheng, Uni-President adopted a traditional outsourcing sandblasting cleaning method, which involved full disassembly and external processing. This outdated cleaning mode brought multiple production bottlenecks:
-
Extremely long downtime: A single cleaning cycle required 3 to 4 days of full line shutdown, resulting in massive production suspension losses.
-
High labor and outsourcing costs: Workers needed to disassemble, transport and reinstall all chain plates, consuming huge manpower and outsourcing expenses.
-
Equipment surface damage: Sandblasting is an abrasive cleaning method that scratches and wears the chain plate surface, accelerating equipment aging and shortening service life.
-
Unstable cleaning quality: Manual sandblasting leads to uneven cleaning, easily causing residual dirt and triggering food safety risks.
Customized Solution: 500W Automated In-Situ Laser Cleaning System
According to the actual size, operating speed and dirt characteristics of Uni-President’s bakery conveyor line, Fangshiheng customized the GY-FLC500M automatic laser cleaning system, realizing non-destructive, in-line and fully automatic cleaning without disassembly.
System Core Configuration
-
Laser Power: 500W high-precision fiber laser
-
Cooling Method: Industrial water cooling for long-term stable continuous operation
-
Maximum Scanning Speed: 30,000 mm/s
-
Applicable Line Size: Adapt to 20-meter-long and 1900mm-wide baking conveyor line
-
Control System: PLC + human-machine touch screen intelligent control
Working Principle & Operation Process
Different from traditional offline disassembly cleaning, this laser cleaning system supports online dynamic cleaning. The conveyor line can keep running normally without shutdown during the cleaning process.
The laser cleaning head is installed on a high-precision gantry linear module. aiming at the 1900mm ultra-wide conveyor surface, the system adopts segmented scanning cleaning: each 200mm width area is cleaned independently. After one section is completed, the laser head automatically shifts position until the entire 20-meter-long conveyor line is fully cleaned. The segmented scanning method ensures uniform cleaning effect without dead corners and completely removes stubborn oil stains and baking residues.
Core Automated Advantages
-
Intelligent recipe storage: Multiple cleaning parameters can be preset and saved to adapt to different dirt levels
-
Precision automatic positioning: servo gantry ensures consistent cleaning accuracy for each area
-
No disassembly required: realize real online cleaning, no need to remove chain plates
-
Integrated dust removal system: instantly absorb smoke and residue generated during cleaning to keep the workshop clean and hygienic
Project Implementation Results & Data Comparison
After applying Fangshiheng’s 500W laser cleaning system, Uni-President’s bakery line maintenance efficiency and comprehensive benefits have been greatly improved, forming an obvious data gap compared with the traditional process.
Time Efficiency Upgrade
Traditional sandblasting cleaning: 3–4 days full line shutdown Laser automatic cleaning: only 7–8 hours of low-interruption cleaning Time efficiency increased by more than 90%
Comprehensive Benefit Optimization
-
Save massive production downtime and greatly improve overall equipment efficiency (OEE)
-
Cancel chain plate disassembly, transportation and outsourcing links, saving high labor costs
-
Non-contact laser cleaning causes no abrasion or damage to the conveyor surface, effectively extending equipment service life
-
No chemical consumables, zero chemical waste, compliant with food-grade environmental protection standards
-
Uniform cleaning effect, no residual dirt, effectively avoiding food safety hidden dangers
Industry Value for Food Manufacturing Factories
This successful cooperation case with Uni-President fully verifies the feasibility and advancement of industrial laser cleaning technology in the food processing industry. It solves the long-standing industry pain point of long maintenance downtime for food conveyor lines.
The solution is widely applicable to various food production scenarios including baking, frying, quick-freezing and packaging. It helps food enterprises achieve three major upgrades: shorter maintenance cycle, lower operating cost and higher food safety level.
Conclusion
Fangshiheng’s customized 500W automated laser cleaning system completely subverts the traditional outsourcing sandblasting mode. It shortens the original 4-day maintenance work to less than one working day, helping food manufacturers maximize production capacity, reduce maintenance costs and build standardized and safe intelligent production lines.
