Founded in 2009 and headquartered in the technological hub of Chengdu, LST Machine has spent over 15 years perfecting the art and science of chocolate manufacturing. By integrating Research and Development (R&D), manufacturing, and global after-sales support, LST has positioned itself as more than just an equipment vendor; it is a strategic partner for confectioners worldwide.
One of the most significant challenges in chocolate production is tempering—the process of controlled crystallization that gives chocolate its snap and glossy finish. LST Machine addresses this challenge through a tiered product strategy that caters to every stage of business growth.
For ice cream parlors, bakeries, and boutique chocolate shops, the CHOCO-D1 (5.5L) is a masterclass in compact engineering. It is designed for versatility, capable of decorating, manual depositing, and maintaining chocolate in a tempered state for immediate use. What sets the CHOCO-D1 apart is its user-centric design: a removable food-grade plastic screw auger allows for rapid cleaning and flavor changes, while dual motors independently control the pump and stirrer to extend the machine’s lifespan. Features like “Night Mode” ensure the chocolate remains melted at a lower power consumption, ready for the next day’s production.
As businesses scale, the TW-TP Series (25L, 60L, 100L) provides the necessary jump in capacity, offering production rates from 60kg to 300kg per hour. These machines are not merely larger versions of the boutique models; they are sophisticated industrial tools. Equipped with PLC and HMI controls, they allow operators to store specific recipes and parameters. The modularity of the TW-TP series is its greatest asset—it can be outfitted with enrobing attachments, vibrating tables, and automatic dosing systems, allowing a single machine to produce molded chocolates, truffles, and enrobed snacks.
Industrial chocolate production begins long before the tempering stage. The texture and “mouthfeel” of chocolate are determined by the particle size of the cocoa solids and sugar. LST’s Chocolate Ball Mills are engineered to achieve the “micron-level” precision required for premium products. Available in capacities ranging from 50kg to 1000kg, these machines utilize high-strength grinding balls to homogenize and refine ingredients into a smooth, creamy mass.
By using AISI 304 stainless steel for all components in contact with the product, LST ensures that the sensory profile of the chocolate remains untainted. The efficiency of these ball mills directly impacts the bottom line; faster refining times and lower energy consumption per batch allow manufacturers to remain competitive without sacrificing quality.
For large-scale manufacturers, the LST Full-Automatic Chocolate Depositing Production Line represents the pinnacle of the brand’s engineering prowess. Capable of producing between 800kg and 2500kg per shift, these lines automate the entire lifecycle of a chocolate bar—from mold feeding and heating to depositing, vibrating, cooling, and de-molding.
Modern consumers demand complexity. LST’s depositing systems (S1000/D1000/T1000) are designed with this in mind. By swapping out depositor heads or syrup distribution plates, a single line can produce:
The system utilizes high-precision cam rotor pumps to maintain a stable ratio of chocolate to inclusions, ensuring that every product on the shelf meets the exact weight and composition specifications. Furthermore, the integration of Delta PLC systems allows for “recipe programming,” where a complete changeover in product type or chocolate color can be achieved in under 15 minutes.
Cooling is often the bottleneck in chocolate production. If chocolate cools too slowly, it loses its temper; too fast, and it may crack or bloom. LST’s Vertical Cooling Tunnels solve this through a multi-stage cooling design that utilizes both direct bottom contact cooling and indirect top cooling. Powered by high-efficiency 15P refrigeration systems and American-imported compressors, these tunnels provide stable, digitally controlled environments (typically 0-10°C).
The “Vertical” design is a strategic innovation for facilities with limited floor space. By utilizing vertical height rather than horizontal length, LST allows manufacturers to increase their throughput without expanding their factory footprint. The fully sealed tunnel lids prevent energy loss, making these systems some of the most energy-efficient in the industry.

Safety is non-negotiable in food production. LST’s equipment is CE Certified, meeting stringent European health, safety, and environmental protection standards. The use of food-grade materials and robust engineering ensures that the machines can withstand the rigors of 24/7 industrial operation.
The relationship with LST does not end at the point of sale. The company offers “Global Lifetime After-Sales Service.” This includes a one-year standard warranty followed by lifelong technical support in English. With remote debugging capabilities, LST engineers can troubleshoot issues across continents in real-time, significantly reducing the need for costly on-site visits and minimizing downtime.
As a factory-direct supplier, LST eliminates the middleman. By benefiting from economies of scale and an optimized supply chain in Chengdu, they offer advanced machinery at a highly competitive price point. This makes high-level automation accessible to medium-sized enterprises that were previously priced out of the market by European manufacturers.
The numbers speak for themselves. With over 2,500 satisfied customers and a strong presence in markets like Germany, Canada, and India, LST has proven that its machines can perform in any environment. Their 4.9/5 rating on independent platforms like Alibaba and a 95.9% on-time delivery rate are testaments to their operational reliability.
LST’s machines are currently used in a diverse array of applications, from traditional chocolate bars to innovative products like oatmeal chocolate and gummy-filled treats. This versatility makes them a favorite for “Original Equipment Manufacturers” (OEMs) who need to pivot quickly to meet changing consumer trends.
The gap between artisan quality and industrial quantity is no longer a barrier. Through the intelligent application of PLC controls, modular design, and precision engineering, LST Machine has empowered confectioners to dream bigger. Whether you are a small shop looking for your first professional tempering machine or a multinational corporation seeking a fully automated production line, LST provides the “Complete Solution.”
In an industry where the margin for error is as thin as a chocolate wafer, LST Machine offers the stability, innovation, and support necessary to ensure your business remains profitable and your products remain world-class. As we look toward the future of confectionery, one thing is clear: the bridge to success is built with the right technology.
