How to maintain the Italian coffee machine how to understand the structure of the Italian coffee machine and how to repair the coffee machine

Coffee machines are technological marvels. These professionally made appliances have come a long way since they were first introduced in the late 1800s. The steam pressure system of the 19th century has evolved into pump drive and electrical technology. Baristas can now operate using an app on their smartphone without touching the machine itself.

Why do we buy refurbished espresso machines?

There are many reasons why refurbished machines are needed, but the two biggest ones are reduced environmental impact and considerable financial savings.

Some refurbished espresso machines cost half their original sales price while still maintaining high standards of appearance and quality. With thousands of brand new commercial machines on sale, refurbished machines may be an attractive option for people on a budget.

It can also be a more sustainable and environmentally conscious investment. It reduces the number of new parts that need to be manufactured and reduces the amount of material that needs to be recycled or placed in landfills. Renovation reduces waste and reduces resource consumption.

Refurbishing old machinery can also reduce risk. Piping and welding in older machines may contain lead, which can leach into water that comes into contact with these components. Continued ingestion of this water may have potentially harmful effects on our organs.

Replacement of old piping and soldering with lead-free components is critical during refurbishment. The Restriction of Hazardous Substances (RoHS) Act of the European Union prohibits the use of any component or substance containing lead in excess of a certain amount in electrical products.

How to Make a Coffee Machine

Although the steps required will vary depending on the machine and its problem, the process will follow the following sequence:

1. Receive machine and diagnose problem

The first step is evaluation. Pest control is especially important for older machines that may not have been used for some time. This involves removing the shell and visually inspecting for signs of insects or rodents, such as faeces or nests. If such signs are detected, appropriate methods will be used to eliminate pests and their traces.

After replacing the casing, you can insert the coffee maker and turn it on. Some problems will be immediately apparent, such as electronic devices that no longer work or steam wands that don't work properly.

However, some problems may be harder to locate and fix. Trained technicians are needed to find and resolve them.

He told me they use software programs to detect problems. "Our machines can tell you where the problem is with alerts…Our [technicians]…will know exactly what to do and how to fix it quickly."

2. removing

After running the diagnostic procedure-and most importantly, after the machine has been completely shut down and unplugged-it is time to disassemble the machine.

It should be completely removed. All panels and trays need to be removed so that the frame remains intact while the piping, cluster heads and boiler remain intact. From there, each part can be carefully removed from the frame. They should be inspected for signs of damage and thoroughly cleaned.

Some components can be recycled. "The most important parts…copper, brass and metal parts have all been fully recycled and are 100% recycled. Sometimes [we] send them back to our major suppliers, such as foundries that fake our team leaders."

After disassembling and cleaning the machine, you can know which parts need repair or replacement. It is usually necessary to replace certain components, such as pumps, valves and screens. Washers and O-rings will need to be reordered and replaced. These are cut off the machine during cleaning.

3. descaling

Now, when the coffee machine is completely disassembled, you can start descaling. Calcium and limestone are the greatest enemies of any machine that uses hot water! These recalcitrant substances form rapidly on any metal surface. Excess is the biggest reason why a machine may need refurbishment in the first place. Boilers and pipes are the main parts that need descaling. Indentations must be handled with caution because they attract more scale buildup.

If proper machinery is not available, descaling must be done manually. This means soaking all ingredients in a solution, usually citric acid, for a long time. The machine saves time and ensures proper and thorough descaling.

Descaling can be a lengthy process, especially if the component has been exposed to particularly hard water. However, all visible evidence of scale must be removed before reinstalling the boiler and piping. Sometimes that may not be possible. When this happens, these parts should be recovered and replaced with new boilers and pipes.

4. Quality Control Inspections and Laws

Using experienced and trained technicians is the best way to ensure quality. However, quality control inspections are also imperative for legal and ethical purposes. They guarantee that refurbished espresso machines are not only safe to use, but also of high quality.

For example, in the UK, any equipment or machinery with a fluid pressure greater than 0.5 bar is affected by the Pressure Systems Safety Regulations (PSSR) 2000 legislation. Even if the equipment was originally manufactured before 2000, it applies to the manufacture, repair and refurbishment of equipment. Quality control checks should ensure that the machine complies with and meets the technician's standards.

Each machine should be subjected to quality control checks, preferably by different technicians, and records and any comments should be kept. While spot checks are often performed when goods are traded in high volumes, for high-quality products such as refurbished espresso machines, it is best to inspect each item.

5. Reassembly and finishing touches

Reassembly usually takes place in the reverse order of disassembly: the boiler will be remounted to the rack first, then the pipes, then the parts, and finally the pallet.

Francesco told me: "We completely rebuilt the machine with brand new materials, pipes, headers and circuit boards," adding that they were all "certified" to European requirements and had the same standards as "brand new" equipment. machine."

All wiring shall be carefully checked by a qualified electrician before connecting panels. Then it was time for the final quality control checks. Finally, any surface work can be done, such as repainting or adding a logo.

The renovation process was time-consuming and laborious, but the results were impressive. It injects life into broken or obsolete equipment. Espresso machines with history and features can perform the same as brand new ones. As the renovation encourages more sustainable and environmentally conscious manufacturing, it takes the coffee industry further into the future.
