Selection and purchase of Coffee maker and Mocha Pot

1. Italian coffee machine

Professional coffee pulling flowers of course can not be separated from professional espresso machine.

Italian coffee machine from the internal structure and system to distinguish words: can be divided into single boiler, letter boiler, double boiler, multi-boiler four categories. These four different structures have certain differences in making espresso coffee. These differences are mainly due to different configurations and heating methods. Here are the advantages and disadvantages of four types of coffee machines.

1, single boiler system coffee machine: hot water and steam and brewing head heated by the same heater, so steam (milk bubble) and hot water (brewing coffee) can not be carried out at the same time.

When making coffee, the temperature of the outlet water of the hot water and steam flushing head will be affected, resulting in unstable conditions. So a single boiler is basically used in household coffee machines or lever spring piston coffee machines. The cost is relatively low.

2, the child boiler system coffee machine: hot water and steam and brewing head although the same boiler heater heating, but the child boiler heating is used with the mother boiler heat exchange heating, so in the use of this type of coffee machine brewing coffee will not have a great impact on the water temperature of the flushing head. However, when hot water is used in large quantities, the impact on the head of the water is relatively large.

3. Double boiler system coffee machine: hot water and steam are heated by the same heater, while the brewing head is heated by another heater, so the use of steam and hot water will not affect the outlet temperature of the brewing head, so the production of Italian coffee is relatively stable. However, double boilers are expensive, so they are generally used for commercial purposes. However, there are currently dual boiler machines positioned with the family. The price is slightly higher.

4, multi-boiler system coffee machine: multi-boiler heating mode is similar to the double boiler, the difference is that each brewing head has its own heater, you can set the water temperature. Therefore, an N-head coffee machine has N+1 boilers (n>2). Multi-boiler systems are more expensive and are suitable for commercial establishments that require higher coffee stability and need to make large quantities of coffee. However, with the development of technology and the popularization of raw materials and coffee, prices will decrease in the future.

The above four coffee machines have their own characteristics, and the actual purchase time is based on their own financial budget and actual needs. Below are the basic elements for choosing an espresso machine.

1. Is it convenient when operating

2, all control buttons reflect whether good

3. Is the stability of the machine good?

4. Whether the heating speed is good

5. Whether the steam outgassing amount is sufficient

6. Whether the dryness of steam is good

Second, the purchase and cleaning of mocha pots

purchase

First, the material, this is the preferred consideration, because the mocha pot will produce high pressure after heating, the quality of the material, directly affect the safety of use. General water storage container materials are edible aluminum and stainless steel two kinds, it is recommended to choose stainless steel. When purchasing, one is to weigh the weight of the pot, you can know the thickness of the dosage, choose a heavier weight; the other is to see the smoothness of the appearance of the pot.

Second, sealing, one is the sealing between the upper seat and the lower seat, and the other is the tightness of the pressure relief valve, whether there is water seepage phenomenon. Airtightness can only be found through use, it is recommended to buy brand-name products such as TIAMO, etc., can have absolute quality assurance.

In addition, different pot types are suitable for different quality coffee beans:

First, the slender mocha pot water storage container is high, deep, slow to heat, high pressure, suitable for cooking shallow roast coffee;

Second, the medium and high mocha pot is suitable for cooking medium roast coffee;

Third, chunky mocha pot storage container wide low, fast heating, low pressure, suitable for cooking deep roast coffee.

Choice of mocha pot type. This is because different pot types of mocha pot, with different degrees of roasting coffee beans. In general, the deeper the roasting degree of coffee beans, the faster the heating and the smaller the pressure in the cooking process, the mocha pot used should be a chunky type; conversely, a slender mocha pot can be used. For medium roast coffee beans, use a medium to high mocha pot.

cleaning

Mocha coffee pot cleaning method Mocha pot must be cleaned in time after use because there will be a lot of coffee grease left in the pot after cooking, especially the middle sealing rubber gasket, if not cleaned in time, there will be a smell of oily dirt when used again in the future. The cleaning method is as follows:

1. Turn the upper and lower pots: Mocha pots that have just been used, because the pot body is hot and very hot, it is difficult to open, and brute force will wear the threads, and then twist them after cooling. If you want to cook again immediately, you can use cold water to cool the pot body, so it is easier to open, for example, right-handed people, the pot handle to the right, the left hand firmly fixed the pot, the right hand up against the root of the pot handle, the thumb buckle pot lid, the whole palm close to the pot body, forward rotation (that is, to the right).

2, pour out the coffee grounds in the powder tank, you can use chopsticks to dig or gently use the meat in the palm to make the coffee grounds in the powder tank fall out, cut can not be hit with hard objects, so that it is easy to cause the deformation of the powder tank and make the upper and lower pots unable to close, and then rinse with water. Flushing should include every part of the entire pot. Conditional and patient can buy a brush for baby bottles to clean the pot. It is best not to use scented detergent, which will make odor residue. Dry the mocha pot with a dry towel so it stays fresh. After using for a period of time, check whether the sealing rubber ring of the pot body is aged, and replace it in time if it is aged.

3, do not use sandy materials and soda water cleaning, this will damage the bright surface;

4, after a long time, inevitably the bottom will change color, it is because of hard water reasons, water mixed with vinegar can go;

5, alloy material coffee pot is best to disassemble all parts stored, so that it remains dry in the air. After a period of time, pay attention to whether the rubber gasket next to the metal filter is complete. If it is not tight, the coffee cannot be boiled.

6, mocha pot can not be washed in the dishwasher.
