LST’s fully automatic chocolate depositing production lines are a testament to their advanced engineering prowess. Models like the LST-S1000/LST-D1000/LST-T1000 offer unparalleled flexibility, capable of producing pure solid, filled, double-color, and nut-mixed chocolates. By simply adding an appropriate biscuit feeding unit, these lines can also integrate biscuits or wafers, expanding product possibilities. The automation extends to every stage: automatic mold feeding, heating, depositing, vibrating, cooling, demoulding, and empty mold circulation.

These lines are controlled by PLC and automatic frequency conversion, with liquid and solid material levels monitored via a human-machine touch interface. Overload protection and product recipe programming storage allow for rapid changes in chocolate color and product type—within just 15 minutes. Independent heating and control systems maintain constant chocolate temperatures even when the main control system is powered down, extending component lifespan. Crucially, two high-precision cam rotor pumps ensure continuous material mixing and stable chocolate ratios, guaranteeing consistent product quality at production capacities ranging from 800-2500 kg per shift. This level of automation significantly reduces labor costs, increases output, and ensures uniform product quality, establishing a new benchmark for efficiency in complex chocolate manufacturing.
