This is an industrial espresso extraction machine. Its operating principle is essentially the same as commercial espresso machines; the difference is that it is engineered specifically for industrial-scale production.The core principle is high-pressure percolation extraction，High-pressure hot water penetrates a tightly packed puck of finely ground coffee within an extremely short period of time, enabling efficient dissolution and emulsification of coffee compounds.

Designed for producing premium coffee concentrate, the machine delivers a daily output of 600–1000 kg.The liquid yield ratio ranges from 1:2.5 to 1:3, with a TDS value of 8–9.Each batch processes 5 kg or 10 kg of coffee grounds, and one full cycle takes 15 to 25 minutes.
