How to maintain the cleaning of coffee machine body

1. Coffee machine body cleaning:

Wipe the fuselage with a wet rag before starting up every day. If you need to use a cleaner, please choose a mild and non-corrosive cleaner to spray it on the wet rag and wipe the fuselage (be careful that the rag is not too wet, and the detergent should not be sprayed directly on the fuselage). To prevent excess water and detergent from seeping into the circuit system and eroding wires to cause short circuit).

two。 Outlet of cooking head:

(1) after each production, remove the hand and press the cleaning button to wash off the coffee grounds left in the cooking head and on the strain. press the cleaning key and shake the handle left and right to wash the cooking head washer and the coffee grounds on the inside of the cooking head after embedding the handle into the socket (note: do not hold the handle tight at this time).

(2) use a special cleaning brush for the coffee machine to clean the coffee grounds on the inside of the head.

(3) this is a folk method, using a coffee spoon and a wet towel, roll the coffee spoon handle into the towel and clean the coffee grounds on the inside of the head.

3. Steam stick:

After using the steam stick to make milk foam, wipe the steam stick with a clean wet dishcloth and turn on the steam switch again, making use of the impulse and high temperature of the steam itself to automatically clean the residual milk dirt in the jet hole to maintain the smooth flow of the air hole.

If there is residual milk crystallization on the steam bar, soak the steam rod in a steel cup filled with 8% hot water to soften the crystallization in the steam hole and on the steam bar, remove the steel cup after 20 minutes, and repeat the first paragraph above. Here, I would like to tell the lonely baristas in many cafes not to clean the steam bar with a wire ball, you hear? I'm sorry. I'm a little impulsive. Continue to write)

4. Boiler:

In order to prolong the service life of the boiler, if the machine is not used for a long time, please turn off the power supply and turn on the steam switch to completely release the pressure in the boiler until the boiler pressure gauge indicates zero. After the steam is no longer ejected, clean the water tray and drainage trough (note: do not turn off the steam switch at this time, turn off the steam rod when hot water drips out the next day to balance the internal and external pressure of the boiler).

5. Water pan:

Before opening the shop or before use, remove the water tray and scrub it with a clean water dishcloth and put it back after drying.

6. Drainage trough:

Remove the water tray and clean the sediment in the drain with a wet rag or napkin, then rinse with hot water to keep the drain unobstructed; if the drainage is poor, pour a small spoonful of cleaning powder into the drain and rinse with hot water to dissolve the coffee residue in the drain. (one more thing to say here, there are many coffee shops where the coffee is always leaking, sometimes the drain is blocked, rinse the drain with a large caliber cup to have a look, but it's still leaking to call the repairman.)

7. Filter cup and filter cup handle:

Rinse with hot water at least once a day to dissolve the coffee oil and sediment left on the handle to prevent part of the oil and sediment from flowing into the coffee during cooking and affecting the quality of the coffee. (ask the evening shift staff to soak in hot water after cleaning, and clean once by the morning shift)

8. Brewing system and filter cup handle:

Remove the filter cup of any filter cup handle to replace the non-porous filter cup for cleaning and disinfection: place a tablespoon of cleaning powder (2-3 grams) into the filter cup; insert the filter cup handle into the socket and check whether it is fully closed; press the cleaning key for 4-5 seconds and press the key to stop. After repeating this several times, relax the handle, press the cleaning key and shake the handle left and right to wash the inside of the cooking head washer until the water in the filter cup becomes clean and colorless. After cleaning, remove the handle, press the cleaning button to make the remaining cleaning powder in the brewing system flow out, press the button to stop after 1 minute, try to make a cup of coffee, remove the smell after cleaning.

If there are multiple water outlets, other water outlets also repeat the above steps for cleaning and maintenance.

two。 Weekly cleaning and maintenance work

1. Filter cup and filter cup handle:

Decompose the filter cup and the filter cup and soak the hand in the cleaning solution (500ml hot water mixed with 3 tablespoons of cleaning powder) for one day. Dissolve and dilute the residual coffee oil (note: the plastic part of the handle should not be soaked in the cleaning solution to avoid the plastic surface of the handle being eroded by the cleaning solution). Rinse all accessories with clean water, scrub with a clean, soft wet rag and replace all accessories.

three。 Monthly and quarterly cleaning and maintenance work:

1. Cleaning of water softener

Turn off the water power of the coffee machine. Adjust the valve to the right to release the pressure by 180 degrees and enter the closed state by adjusting 90 degrees to the left when the pressure is over. Adjust the valve 90 degrees to the right to enter the closed state. Open the softening bucket lid and put in 1 kilogram of salt and soak for 8 hours or overnight. Time to reset the softening bucket lid, set the valve 90 degrees to the left, adjust the valve to the right 90 degrees, open the water source, and rinse for half an hour until there is no smell. Adjust the lower valve to the left 180 degrees, turn on the power switch, you can use the coffee machine.

Maintenance and cleaning cycle: 1 month

two。 Replacement of filter

Turn off the water source power with a special handle to open the filter and replace its filter element. After the replacement, turn on the water source to check that the water source is

There is no leakage, such as turning on the coffee machine power normally.

Maintenance and replacement cycle: coarse filtration: 2 months activated carbon: 3 months fine filtration: 6 months

3. Cleaning of filter screen for brewing head

Remove the strainer of the brewing head (if the machine has just used hot hands) and soak into the cleaning solution (500ml hot water is mixed with 3 tablespoons of cleaning powder) to release coffee oil dregs and clogs from the filter hole and strainer: wash all accessories with clean water and scrub with a clean and soft wet rag: check whether the strainer is smooth and install all the accessories.

Maintenance cycle: 1 month

4. Bubble head sealing ring

The sealing ring of the bubble head bites with the powder filling handle for a long time and plays a sealing role with the powder filling handle under high pressure. Because the sealing ring of the brewing head of the coffee machine is high for a long time and accumulated with the powder filling handle, the sealing ring of the brewing head will be carbonized, making it lose its sealing effect. When there is brewing, coffee is missing from the head of the coffee machine, which is due to the inaccurate flow rate of coffee. The bubble sealing ring should be replaced at this time.

four。 Some precautions in the use of coffee machine

1. Do not use the coffee machine when the water is cut off.

two。 Before operating the coffee machine, please pay attention to use only when the boiler pressure pointer reaches the green area (1-1.2bar): the temperature of the steam rod, hot water outlet nozzle and cooking outlet is very high, please do not expose your hands nearby to avoid the damage caused by the high temperature.

3. Please pay attention to whether the pressure gauge is in the green area (8-10bar) when pumping water by the voltage stabilizing motor.

4. In order to prevent the danger of overheating, please keep the power supply smooth, ventilation entrance, outlet should not be blocked: do not cover towels or similar things except cups and plates on the warm cup rack.

5. The cup must be completely dry before it can be placed on the warm cup rack: do not place anything other than the cup plate on the warm cup rack.

If you do not use the coffee machine for a long time, please turn off the power supply and completely release the pressure in the boiler of the machine.

7. Machinery and equipment and any accessories can not be scrubbed with wire, steel brush and other items: must be scrubbed with a wet rag message.

8. Put the right amount of coffee powder into the handle of the filter cup and press it carefully with the handle. Note: do not leave coffee powder on the edge of the filter cup, so that there will be no air in the cooking process to reduce the pressure, but also can prolong the life of the cooking head washer.

9. When inserting the handle of the filter cup into the cooking head, please insert it tightly. Otherwise, the handle will bounce off due to excessive pressure during production.
