The global confectionery industry is undergoing a massive transformation driven by rapidly evolving consumer preferences, demands for higher production efficiency, and stringent food safety regulations. Standing at the forefront of this industrial revolution is Chengdu LST Science and Technology Co., Ltd. (LST Machine). Established in 2009 in Chengdu, Sichuan Province, LST Machine has steadily built an international reputation as an elite manufacturer specializing in end-to-end chocolate production and packaging equipment.

Operating from an expansive, modern manufacturing plant spanning over 6,500 square meters, LST seamlessly integrates research and development, precision manufacturing, global sales, and comprehensive after-sales support. By combining industrial-grade automation with accessible customization, Chengdu LST is actively setting new quality and efficiency benchmarks for confectionery producers worldwide—from boutique artisanal chocolatiers to high-volume commercial manufacturers.

A Comprehensive Portfolio Built for Precision and Scale

LST’s strength lies in its ability to address every stage of the chocolate manufacturing line. Rather than delivering standalone hardware, the company engineers interconnected processing ecosystems tailored to specific operational scales and product complexity.

1. High-Precision Chocolate Tempering Machines

Tempering is the foundation of premium chocolate, dictating gloss, snap, and melt temperature. LST caters to every operational tier with a tiered equipment strategy:

• Commercial & Artisanal (CHOCO-D1): Featuring a compact 5.5-liter capacity, the CHOCO-D1 is engineered for pastry shops, ice cream parlors, and craft bakeries. It boasts a removable food-grade plastic screw dispenser for rapid cleaning, dual motors dedicated to pumping and stirring, pedal-controlled dosing, and an energy-efficient night mode to keep mass liquid overnight.
• Industrial Series (TW-TP Series): Designed for commercial environments, the TW-TP25, TW-TP60, and TW-TP100 models handle tank capacities from 25L to 100L, delivering hourly outputs between 60 kg and 300 kg. Managed via PLC/HMI touchscreen interfaces, these modular units easily integrate attachments for enrobing, molding, and truffles.

2. Automated Chocolate Depositing and Molding Lines

For high-throughput facilities, LST’s flagship automated depositing series—including the LST-S1000, LST-D1000, and LST-T1000—represents a major leap in engineering sophistication. Capable of outputting between 800 kg and 2,500 kg per shift, these lines automate mold feeding, mold baking, depositing, mold vibrating, cooling, demolding, and empty mold recycling.

Utilizing high-precision dual cam rotor pumps and servo mold-lifting mechanisms, LST depositing lines produce intricate confectionery formats, including solid bars, center-filled pralines, two-color swirl chocolates, and nut-mixed matrices. Optional biscuit and wafer feeding units allow manufacturers to dynamically expand their SKU offerings with minimal setup changes. Furthermore, the system stores multi-recipe configurations, enabling product line switches in under 15 minutes.

3. Micron-Grade Ball Mills and Refining Equipment

Texture dictates consumer perception. LST ball mills—available in capacities ranging from 50 kg to 1,000 kg—refine cocoa mass, sugar, and fat blends down to micron-level particle sizes. Constructed entirely from AISI 304 stainless steel, these machines deliver uniform particle size reduction, enhancing mouthfeel, consistency, and flavor release while maintaining strict food safety standards.

4. Energy-Efficient Vertical Cooling Tunnels

To preserve temper and prevent fat bloom, proper cooling is critical. LST vertical cooling tunnels incorporate dual 15P refrigeration systems powered by imported U.S. compressors and variable frequency drives. Featuring a fully sealed design that prevents thermal energy loss, these systems utilize bottom direct-contact cooling paired with top indirect cooling. The vertical architecture drastically minimizes factory floor footprint without compromising residence time or cooling efficacy.

Engineering Innovation and Technical Rigor

To maintain its competitive edge in a crowded global marketplace, Chengdu LST prioritizes technical excellence and proactive R&D. The company’s engineering staff systematically pushes the boundaries of food processing technology, integrating globally recognized components—such as Delta PLCs, Schneider electronics, and premium American refrigeration compressors—to maximize machine longevity and uptime.

This commitment to quality control is reinforced by international regulatory compliance. LST machinery holds full CE certification, validating adherence to European health, safety, and environmental protection standards. By combining robust mechanical design with intelligence-driven software, LST machines optimize energy usage, reduce raw material waste, and deliver lower total cost of ownership (TCO) across their lifecycle.

Global Footprint and Unwavering Support

Serving over 2,500 satisfied clients across North America, Europe, South America, Asia, Africa, and Oceania, LST has demonstrated global market adoption. The brand has built particular strength in demanding markets including Germany, Canada, and India.

A major key to LST’s international success is its customer-centric service model. Recognized for operational transparency and performance reliability, LST maintains high customer ratings on independent third-party platforms, backed by a 95.9% verified on-time delivery rate. To support its international client base, LST provides:

• Lifetime Technical Support: Free, lifetime English-language engineering consultation.
• Remote Debugging & Diagnostics: Rapid resolution of software adjustments and operational troubleshooting via digital connectivity.
• Turnkey Customization: Custom line design, mold configuration, machine branding, and bespoke packaging solutions.
• Comprehensive Warranty: Standard 1-year comprehensive machinery warranties coupled with available on-site technical deployment.

Empowering the Future of Confectionery Manufacturing

Whether helping an emerging artisanal brand transition to automated dosing or engineering a multi-tier, fully automated production plant for an established food enterprise, Chengdu LST provides the strategic balance of quality, versatility, and affordability. By offering direct-from-factory pricing that leverages substantial economies of scale, LST lowers the barrier to entry for advanced automation technology.

As consumer demand for innovative chocolate formulations, complex fillings, and dietary variations continues to surge, Chengdu LST Science and Technology Co., Ltd. remains dedicated to powering the next generation of confectionery excellence through superior engineering, continuous R&D, and world-class global service.
