Coffee shop owner, barista must read-- the most complete general knowledge of coffee machine maintenance

Jiaxiang Guide: any machine has a service life and needs maintenance. The same is true of coffee machines. As a barista, you not only need to master the skills of making coffee drinks, but you must also know how to take good care of your "buddies" and take good care of the coffee machine you will work with tomorrow.

1. Water filter: the water filter is composed of resin and activated carbon. It can effectively filter the impurities and odors in tap water, so as to achieve the water quality needed to brew coffee and prolong the service life of the coffee machine.

Resin: it can effectively filter calcium and other minerals in water and has the function of softening water.

Activated carbon: can effectively filter chlorine in the water, and other odors, to achieve the water quality needed to make coffee.

Filter element: the replacement time is determined by the local water quality, usually once every three to six months.

two。 Steam pipe: every time you heat a drink or foam, you must immediately release a large amount of steam, flush the remaining liquid or milk out of the steam pipe to avoid blockage, and wipe it to avoid scaling.

3. After brewing a large amount of coffee, in your spare time, please lock the cooking head with an empty powder handle, press the free brewing button, and wash the coffee powder left on the cooking head with a large amount of hot water to avoid blockage of the filter.

A put about 1 tablespoon of powder into the cleaning filter and lock the cooking head, press the free brewing button, press the normal brewing time (about 5-8 seconds) to stop, then let the powder melt, and soak with the filter for 30 seconds, repeated 3 times. Then remove the support and dump the sewage.

B gently lock the support and press the free bubble button, then gently release, lock, release, lock, and repeat the action back and forth (let a lot of water up and down) until there is no residue in the cleaning strainer.

6. The support should be soaked in hot water once a week to clean the strainer that may be blocked.

7. The coffee maker water plate and the bottom drain of the coffee machine must be cleaned every day to prevent the residual coffee grounds from clogging the drain.

8. Pay attention to whether the pressure gauge is in the normal range. (top pointer 1. 0-1.1bar, bottom pointer 8-9bar when brewing coffee)

9. Coffee machines with more than two heads must be used evenly to avoid blockage at the other end.

10. When hot water is rarely used in the coffee maker, please release a lot of hot water within a week.

11.

twelve。 If the local water quality is poor, the bottom water of the coffee maker must be put in every week.
