Espresso Machine Espresso machine is the most popular coffee machine used in coffee shops. The starting price is from thousands of baht to hundreds of thousands, even millions. As for the difference between thousands and hundreds of thousands, it is the design, beauty, stability of coffee brewing, and functionality.
Working principle of the machine Using hot water with steam pressure in a boiler to force water through the ground coffee to extract the coffee with full concentration and aroma.
There are many types of espresso machines. Depending on the area of use and the size of the structure, it can be divided into many types according to the mechanism of operation, such as the number of brewing heads, the size of the machine, the boiler, the pressure control system, the heating system of the coffee machine, and the espresso machine system.
This type of machine has only one boiler that both makes espresso and steams milk. Users must choose whether to extract espresso or steam milk, because steaming milk generally uses a higher temperature than espresso extraction. Since the optimum temperature for steaming milk and extracting espresso is different, users must wait for the boiler and adjust the temperature to be suitable before use, which is considered a disadvantage of this type of machine.
It is a machine that has been developed from a single boiler. The components still have only one boiler, but there will be a pipe through the middle of the boiler that functions to exchange the heat of the water flowing through the pipe with the hot water in the boiler, causing the water flowing through the pipe to have the same heat. The water flowing through the pipe will head to the group head for espresso extraction. Therefore, the water in the boiler is used only for steaming milk, allowing espresso and milk to be extracted at the same time without having to choose one or the other. However, the problem with this type of machine is that if espresso is extracted continuously, the hot water may not be enough for use, and there may be a problem with unstable temperatures from either water that is not hot enough or water that is too hot from water that has been left in the pipe for a long time.
It is a further development from the heat exchange machine. A machine with two boilers has separate boilers for steaming milk and extracting espresso, allowing for better temperature control for brewing and steaming milk. The espresso can be extracted continuously with a more stable temperature. The only problem with this type of machine is its high price.
It is a design that combines the advantages of a double boiler and a heat exchanger. The water that goes into the espresso extraction boiler flows through the milk steam boiler, causing the water entering the espresso extraction boiler to be hot to make the temperature in the espresso extraction boiler more stable.
It is a boiler system found in larger coffee makers with two or more brewing heads. Multi-boiler heat exchanger, each group head has a separate boiler, and a large boiler for milk steaming, allowing different temperature settings for each group head for brewing different coffees.
In addition to the systems mentioned, there are other devices that need to be taken into account, such as PIDs and water pumps, as well as special details of some brands that allow users to independently control other variables.
What size coffee maker should you choose that is appropriate for the size of your shop? The sizes of coffee makers differ because of the different sizes of boilers (water boilers) and conveniences. Large coffee makers have larger boilers than small coffee makers, giving them the ability to brew coffee continuously better because the larger boiler size will help keep the temperature of the water used to brew coffee more stable when brewing continuously. Coffee makers have boiler sizes that are divided into 3 sizes.
- The price of coffee we will sell Of course, if we plan to set the price of coffee in the range of 25-45 baht, we may not need to invest in a very high-priced coffee machine because the payback period will be long.
- Coffee machine price Coffee machines suitable for investment in our fresh coffee market will be around 25,000-100,000 baht for a 1-head machine and 90,000-150,000 baht for a 2-head coffee machine. Sometimes, investing once in a good coffee machine that can support high sales will help save a lot of investment.
