Solenoid valves in espresso machines control water and steam flow for brewing and frothing, manage cleaning and rinsing processes, and maintain stable extraction pressure for optimal coffee quality.

All three models are equipped with two three-way solenoid valves and one two-way solenoid valve by JIAYIN, ensuring high reliability and precise control.

Using two JIAYIN three-way solenoid valves and one two-way solenoid valve in a coffee machine enhances performance by enabling precise control over water and steam flow. The three-way valves efficiently manage brewing and frothing processes, while the two-way valve aids in controlling specific functions. This setup ensures reliable operation, simplifies maintenance, reduces energy consumption, and provides excellent sealing to prevent leaks, all contributing to optimal coffee quality and machine safety.

Flow meters are integral to the CM5700™, 5700GENSE™, and 5700PRO™, enhancing consistency and efficiency in coffee making.

A flow meter in a coffee machine measures the precise amount of water flowing through the system. This ensures accurate dosing for brewing, helps maintain consistent coffee quality, and allows for adjustments in water flow rates to optimize extraction. By providing real-time data, a flow meter helps improve the machine’s efficiency, prevents over-extraction or under-extraction, and aids in monitoring and maintaining the machine’s performance.

Each model is equipped with ULKA 20 bar electromagnetic pumps, offering high-pressure extraction. The ULKA 20 bar solenoid pump offers superior high-pressure extraction capabilities, enhancing both the quality and flavor of coffee.

A grinder is a crucial component in coffee machines that crushes beans to a consistent size, essential for optimal extraction and flavor, with conical burr grinders offering uniform particle size and reduced heat, and flat burr grinders providing precise grind settings but potentially more heat and static.

All CM5700™, 5700GENSE™, and 5700PRO™ models feature a conical burr grinder with 15 precise grind settings, offering several advantages over flat burr grinders:

(1) Reduced Powder Residue: Minimizes powder residue, maintaining consistent grind quality and simplifying cleaning.

(2) Lower Static Issues: Reduces static, preventing coffee grounds from sticking to the machine.

(3)Quieter and Cooler Operation: Operates with lower noise and heat, preserving the coffee bean's flavor.

(4) Improved Particle Uniformity: Delivers uniformly ground coffee, ideal for high-quality brews.

(5) Maintenance and Durability: The high-end design ensures easy maintenance and robust durability.

The CM5700™, 5700GENSE™, and 5700PRO™ all utilize a Thermal Block System. This system features one or more heating blocks that directly heat the water flowing through the coffee machine. The main advantages of the Thermal Block System include rapid heating, precise temperature control, energy efficiency, and a compact design. It works by using electric heating elements within the blocks to quickly heat the water and maintain a stable temperature, ensuring optimal coffee flavor.

The CM5700™, 5700GENSE™, and 5700PRO™ all feature PID Temperature Control, which provides precise and stable water temperature regulation to ensure consistent coffee quality. This technology optimizes flavor by reducing temperature fluctuations and enhances energy efficiency and user convenience.

Key benefits of PID Temperature Control include:

(1) Precise Temperature Control: Maintains stable water temperature for consistent brewing and improved flavor extraction.

(2) Enhanced Coffee Quality: Reduces flavor variations caused by temperature changes and minimizes quality inconsistencies.

(3) Energy Efficiency: Adjusts heating power precisely to avoid overheating, reducing energy consumption and heat-up time.

(4) User-Friendly: Automatically adjusts temperature without manual intervention, reducing maintenance and simplifying operation.
