In the food manufacturing industry, the stability, cleanliness, and automation level of material conveying systems directly impact production efficiency and product quality. As a pneumatic conveying system manufacturer with 15 years of industry experience, Wijay recently completed an automated sauce relocation batching project for Ligao Foods, covering the entire process from raw material bag opening and metered conveying to tank management. This article systematically presents this typical case from the perspectives of project background, system architecture, technical details, and implementation outcomes, showcasing the engineering capabilities of a professional pneumatic conveying system manufacturer in complex food production scenarios.
Project Background: Ligao Foods’ Automation Upgrade Needs
Ligao Foods is a company specializing in the R&D, production, and sales of bakery raw materials and frozen bakery products. Its business spans multiple areas, including bakery raw materials, frozen bakery products, baking sauces, beverage ingredients, and snack foods. The company operates multiple production bases in Guangzhou, Foshan, Zhejiang, and other locations, and has introduced internationally advanced automated production lines, continuously driving the intelligent upgrade of its manufacturing systems.
In this project, Ligao Foods needed to systematically relocate and automate the material batching process in its existing sauce production workshop. Traditional manual batching methods presented bottlenecks in efficiency, accuracy, and food safety control. The customer sought an integrated system capable of automatic bag opening, conveying, dosing, and storage of powder materials to enhance production line continuity and process stability.
Overall System Design: Parallel Lines for Cold and Hot Sauces
As the project contractor, Wijay fully leveraged its technical strengths as a manufacturer of pneumatic conveying systems to design and install a customized automated sauce relocation batching system. The system consists of two main parts: automatic powder batching for cold sauce and automatic powder batching for hot sauce, covering four cold sauce production lines in Nansha and two newly added hot sauce production lines.
The project scope included full-process services such as system design, equipment procurement, transportation, unloading, installation, and commissioning. The overall system adopts a modular design, ensuring that while meeting process requirements, it also facilitates ease of maintenance and future expansion.
Cold Sauce Production Area Configuration
The cold sauce production area is equipped with three 200-liter weighing tanks for high-precision dosing and batch feeding. This area primarily handles powder materials in low-temperature environments, requiring strict temperature control and moisture prevention during conveying.
Hot Sauce Production Area Configuration
The hot sauce production area is equipped with three 500-liter weighing tanks to meet the requirements of larger batches and high-temperature operating conditions. The two systems operate in parallel, enabling production line division while ensuring overall production rhythm coordination.
Core Technical Details: End-to-End Automation from Bag Opening to Storage Tanks
The technical challenge of this project was achieving fully automated control of powder materials from raw material entry into the workshop to final batching, while ensuring conveying accuracy, equipment cleanliness, and system stability. As an experienced pneumatic conveying system manufacturer, Wijay integrated several core technologies into the system design.
Automatic Bag Opening and Material Feeding
The front end of the system uses robotic arms to automatically feed materials into four feeding stations, replacing traditional manual bag-opening methods. This significantly reduces labor costs and material exposure risks. After bag opening, the powder is screened to remove foreign matter, ensuring purity for subsequent processes.
Pneumatic Conveying and Dosing System
The overall system conveying capacity is 3 tons per hour. It uses enclosed pneumatic conveying pipelines to transport materials from the feeding stations to six 7-cubic-meter storage tanks. During conveying, magnetic separation equipment is installed to effectively remove magnetic impurities from the powder, suitable for high-quality food production scenarios sensitive to metal contaminants.
Dehumidification and Universal Discharge
The storage tank section is equipped with a dehumidification and drying system to prevent powder from absorbing moisture and caking during storage, ensuring material flowability and batch consistency. The discharge section employs a universal discharge structure that adapts to the interface positions of different downstream equipment, improving on-site piping flexibility.
Project Implementation and Delivery
The project officially commenced construction in October 2025. After stages including equipment installation, pipeline connection, electrical commissioning, and system integration, all commissioning work was successfully completed in March 2026. Throughout the implementation process, the Wijay team maintained close collaboration with Ligao Foods’ production and engineering departments, ensuring that the construction schedule aligned with the customer’s existing production plans.
After the system went live, it achieved the expected targets in terms of operational stability, dosing accuracy, and equipment cleaning convenience. Ligao Foods gave high recognition to the product quality, system performance, and technical services demonstrated by Wijay in this project.
