I. Core Specs at a Glance: Solid Performance Builds a Legend As the flagship model of the LADETINA brand under Dazheng Coffee Group, the “Legend” Two-Group Semi-Automatic Espresso Machine (Model AT2-2) focuses on commercial-grade stability and intelligent operation. Key specifications are as follows: Specifications • Boiler System: Dual-boiler design (coffee boilers: 1L × 2, stainless steel; steam boiler: 7L, stainless steel) • Power: 5600W • Voltage/Frequency: 220V / 50–60Hz • Dimensions: 791.6 × 680 × 477.6 mm • Display: 7.0” touchscreen (intuitive control; parameters adjustable in real time) ⸻ II. Technical Breakdown: How Three Core Features Create the “Legend” 1. T2 Multi-Boiler System • Independent operation: Two dedicated coffee boilers plus a separate steam boiler prevent temperature fluctuations caused by function switching in single-boiler machines, ensuring precise temperature control while pulling shots and steaming milk simultaneously. • Material advantages: Food-grade stainless-steel boilers offer corrosion resistance and efficient heat transfer. Combined with PID temperature control, the system achieves ±0.5°C precision, accommodating different roast levels and coffee profiles. 2. Saturated Brew Group + Pre-Infusion: Stability and Flavor Assurance • Saturated design: The brew group remains water-saturated, reducing flow fluctuations during extraction. Together with PID control, it improves espresso crema uniformity by 30%. • Programmable pre-infusion: Pre-infusion time can be freely set to unlock deeper flavor layers—especially suited to light roasts and single-origin coffees requiring delicate extraction. 3. Intelligent Operation: From “Experience-Driven” to “Data-Driven” • 7” touchscreen: One-tap parameter adjustment replaces cumbersome traditional buttons. Real-time display of per-cup and cumulative output data helps cafés optimize workflow and efficiency. • Parameter copy/replication: Presets can be stored on screen to standardize
