The capsule coffee machine is uniquely designed because it does not require on-site grinding of coffee beans. Its core lies in the special structure adapted to the capsules and the automated extraction system. The following is a specific analysis:
Capsule adaptation and puncture design
The concave area on the top of the capsule coffee machine is the capsule compartment, which is made of food-grade plastic and has an anti-slip texture on the surface. The bottom of the capsule chamber is hidden with a stainless steel piercing device, and three sharp metal needles are distributed in a triangular pattern. When the capsules are placed in, the mechanical transmission system drives the tray to rise. Metal needles precisely Pierce the aluminum foil seal to ensure sealing and prevent the coffee grounds from getting damp.
High-efficiency heating and temperature control system
The heating system is located in the middle section of the machine and includes a micro boiler and a heat exchanger. The heating tube with a power of 900W is hidden inside a copper heat conduction plate. Combined with a PID temperature controller, it can stabilize the water temperature at 92℃±2℃ within 20 seconds. The water flow pipe is made of medical silicone material and features a spiral pipe design with an inner diameter of 2.5 millimeters, which not only ensures the water flow rate but also extends the heating time. The thermal sensor detects the water temperature every 0.5 seconds and automatically adjusts the heating power through the relay.
Intelligent extraction and pressure control
The extraction system consists of 15 precision components, including a rotary pump, a pressure valve and an extraction head. The rotary pump provides a stable pressure of 15bar. The stainless steel piston vibrates 300 times per minute to ensure that the water flows evenly through the coffee grounds. The pressure valve adopts a spring regulation design and automatically releases pressure when the pressure exceeds 19bar. The extraction head is equipped with a double-layer filter screen inside, made of 304 stainless steel with a mesh diameter of 0.3mm. It can effectively intercept fine powder while allowing oil to pass through smoothly.
Capsule identification and compatibility design
The capsule recognition module integrates photoelectric sensors and pressure sensors. When capsules of different brands are placed in, the raised code at the bottom will trigger the corresponding recognition program. The pressure sensor can detect whether the capsule is in place to prevent idling and damaging the equipment. This system can automatically match over 30 common capsules on the market, with an error rate controlled within 0.3%.
Wastewater treatment and anti-backflow structure
The wastewater collection device is located at the bottom of the machine and consists of two independent chambers. The front chamber collects the coffee grounds after extraction, and the rear chamber stores the wastewater from flushing the pipelines. When the water volume reaches 150ml, the float valve triggers the automatic drainage program. The anti-backflow design ensures that wastewater will not flow back and contaminate the water purification system. The rubber sealing ring can withstand high temperatures up to 120℃.
Low noise and easy-to-maintain design
The water pump system adopts a gear transmission structure, with a ceramic shaft core and graphite bearings, and the operating noise is less than 45 decibels. The water inlet and outlet are equipped with magnetic quick-connect connectors for easy disassembly and cleaning. The water flow path is designed with three 90-degree bends to enhance the turbulence effect of the water flow and improve the uniformity of coffee extraction. The interior of the fuselage is filled with a sensor network, including water temperature probes, pressure gauges, flow meters and position sensors, which are connected via CAN bus and exchange data 200 times per second.
