Huijia is the largest and most professional Chinese coffee machine brand, and Huijia's counters can be seen at major coffee appliance fairs across the country. Since 1975, Huijia has been OEM home appliances for brands in Europe, the United States, Japan and other developed regions, producing OEM and ODM products, and is still OEM automatic coffee machines for Saeco, and is also responsible for the production of some batches of Fetco's drip coffee machines and some models of Iberital's high-end home coffee machines.
 
Huijia's home coffee machine product line is divided into three grades, which are named professional coffee machines, semi-automatic coffee machines, and home coffee machines. But in fact, these three grades are all household machines, except for accessories, shape design, and some edge function differences, the biggest difference between these three series is the number of heating blocks. There are three heating blocks for the professional level, two for the semi-automatic level, and only one for the home level.
 
La Marzocco's multi-boiler design was the obvious choice when it came to sequencing the heating systems, but each boiler required a matching heating system, and the cost would increase exponentially. The price of the sub-boiler is relatively low, and the extraction sub-boiler is placed between the large steam boilers, and the extraction boiler is heated by the steam boiler with a higher temperature, while keeping the two boilers relatively independent. However, due to the small capacity of the sub-boiler, the temperature change will be relatively large during continuous extraction.
 
Theoretically, block heating is a characteristic of entry-level coffee machines, which use very little water in a single heat, the temperature is unstable, and the temperature is prone to plummeting when the cup is continuously discharged. However, Huijia KD-3 series uses three heating blocks to simulate the dual boiler heating system to achieve precise temperature control, which can perfectly cope with the situation of a small number of cups, and the cost is much lower than that of the double boiler structure.
 
In the case of a single small amount of extraction, Huijia's professional-grade home coffee machine is not much inferior to many big brands led by La Marzocco, compared to their price of 3-50,000 yuan, Huijia's KD-3 series of top household machines, the price is only hovering around 8,500 yuan. The price of the semi-automatic series of KD-2 series double heating blocks is as low as about 4500 yuan, if you are relatively sensitive to price and have certain requirements for performance, Huijia is a very good choice.
 
The pressure pump used in Huijia's top home coffee machine has been treated with shock absorption and noise reduction, with high quality, and the noise will be much smaller than that of the common vibrating pressure pump during operation, and the body jitter amplitude is very small, and the extraction pressure can be increased to 9-10bar within 2s, with high extraction efficiency. The design is made of mirrored stainless steel, which is visually good and is also very easy to clean.
 
In addition, the Huijia commercial coffee machine KD-410 is also worthy of the attention of enthusiasts, it only has one group of brew heads, and it is fully adaptable to home scenarios in all aspects. The performance is extremely barbaric, not only equipped with double boilers, but also provides a rotary pressure pump, as for the standard configuration of high-end models such as PID temperature control, KD-410 is readily available, but the price is only 14800 yuan. At the same price, it is difficult to find a product on the market that is close to KD-410 in terms of performance.
