In the highly competitive field of commercial coffee machines, the slightest difference in coffee quality may affect the customer experience and the reputation of the store. As one of the key equipment that determines the flavor of coffee, the choice of its core component - the motor is crucial. In recent years, DC brushless motors have gradually become the new favorite of commercial coffee bean grinder motors, bringing a new revolution to the coffee industry.
1. The perfect combination of high efficiency and energy saving
Traditional grinders generally use brushed motors or AC induction motors. During the operation of brushed motors, sparks will be generated due to the friction and contact between the brushes and the commutator, causing large energy loss. Although the AC induction motor has no carbon brush structure, the asynchronous motor, slip loss, copper loss and iron loss are greater than those of the DC motor. The DC brushless motor uses electronic commutation technology to avoid this energy loss, allowing electrical energy to be converted into mechanical energy more efficiently. The efficiency of brushed motors is generally 65%-75%; the efficiency of AC induction motors is generally lower, generally 55%-70%; and the efficiency of brushless motors can generally reach 80%-90% (up to 95%). For commercial coffee machines, this means that during busy business hours, a large number of coffee beans can be ground with lower energy consumption, which not only reduces operating costs, but also conforms to the current trend of green society and energy conservation and environmental protection.
Take a medium-sized coffee shop as an example. A large number of coffee beans need to be ground every day to meet customer needs. For a grinder using a traditional motor, the monthly electricity bill may account for a large share of the cost. After replacing the grinder with a DC brushless motor, the energy consumption is significantly reduced, and the monthly electricity bill can be saved by 15% - 25%, which saves the coffee shop a considerable amount of money in the long run.
2. Stable performance and precise grinding quality
The DC brushless motor has excellent speed regulation performance and torque output characteristics. It can be precisely controlled by the driver to accurately adjust the motor grinding speed (500-2000rpm) and change the torque (5-15kg) to adjust the grinding fineness according to different coffee bean varieties, roasting degree and barista's needs. Whether it is espresso that needs fine grinding or relatively coarse French filter coffee, the DC brushless motor can stably output the required grinding effect to ensure that the taste and flavor of each cup of coffee are in the best state.
In a boutique coffee shop known for its quality, baristas can accurately control the grinding parameters of the grinder driven by the DC brushless motor through a stable and reliable driver, and find the most suitable grinding degree for each coffee bean, so as to present customers with unique flavor and rich taste coffee drinks, which has won the favor of many coffee customers.
3. Low noise operation, improve the working environment
In commercial coffee shops, it is often necessary to handle multiple tasks at the same time, such as making coffee, receiving customers, cleaning the environment, etc. Traditional motor-driven grinders produce a lot of noise when working, which not only affects the barista's work experience, but may also cause discomfort to customers in the store. The operating noise of the DC brushless motor is significantly lower than that of the brushed motor and AC induction motor. In indoor environments, it is about 35-45dB. Create a quieter and more comfortable working and consumption environment for the coffee shop.
Imagine that in a warm coffee shop, without the noise of the grinder, customers can taste coffee, read books or talk with friends in a relaxed and pleasant atmosphere, and the barista can also focus more on coffee making, bringing customers a better service experience.
4. Long life and reliability
The commercial environment has extremely high requirements for the stability and durability of the equipment. Since the DC brushless motor has no brush wear problem and uses bearings with good performance, the service life is greatly extended compared to the traditional brushed motor. Even for AC induction motors, the life span is more than doubled. The expected life is 20,000 hours, and 20,000-40,000 hours if the use conditions are better. This means that coffee shops do not need to frequently replace the grinder motor, reducing the cost and time of equipment maintenance and repair, and ensuring the normal operation of the coffee shop.
For a 24-hour chain coffee shop, the high reliability and long life of the grinder are crucial. The grinder using a DC brushless motor can withstand the test of long-term and high-intensity use, providing a strong guarantee for the continued stable operation of the store.
With the continuous popularization of coffee culture and the continuous growth of the coffee market, the performance and quality requirements for commercial coffee grinders are also constantly increasing. Donghong Electromechanical BLDC60 DC brushless grinder motor has undoubtedly become a powerful weapon to improve coffee quality and commercial competitiveness with its advantages of high efficiency and energy saving, precise grinding, low noise and long life. In the future coffee industry, we have reason to believe that DC brushless motors will continue to lead the trend and bring a better coffee experience to the majority of coffee lovers.
