Manual coffee machines: refers to the old-fashioned ones with manual joysticks. Technically, they are very old, but they allow you to experience the wonderful feeling of pressing coffee by hand. This kind of coffee machine uses pistons and springs to generate pressure, although the machine manufacturing process is very traditional, but many people like this old-fashioned machine, if you only have natural gas as the energy source of the coffee machine, then the manual coffee machine is your only choice.
Automatic coffee machine: or water automatic coffee machine, equipped with an electronic control system to control the amount of water per cup of coffee, the system can decide when to stop the flow when making a cup of coffee (the simplest). The most common way to destroy espresso is to allow too much water to pass through the coffee powder, resulting in excessive extraction, a water monitoring device that greatly reduces the risk of poor production, and such coffee machines have become the first choice in hotels and large coffee shops.
Semi-automatic coffee machine: use buttons or joysticks to start or stop the coffee making process. The water pump continuously pumps the water up and through the coffee powder until the operator button is turned off. The advantage of this coffee machine over the manual coffee machine is that the water pressure is constant throughout the production process, and no more manual process is required. The operator's skill and alertness are critical.
Fully automatic coffee machine: this coffee machine can grind, fill and make coffee, all without the operation of hands, and some models can even heat milk and distribute it to coffee proportionally. The fully automatic coffee machine is the fastest growing in the entire coffee industry. However, more expertise and services are needed for their maintenance, and this kind of coffee machine is most suitable for office or self-help environment, but the coffee produced by this machine will not impress you or bring repeat customers. It will only monotonously repeat the same coffee without any change.
