Dry thoroughly before placing beans back into the hopper.

 

Bean to Cup Cleaning Schedules

Bean to Cup machines require a little more cleaning than traditional espresso machines. This is because the technology is more complicated and fresh milk is delivered directly through the machine. Milk is a live product as has to be flushed through regularly.

Cleaning schedules detailed below are for guidance only and may vary depending on machine type, quantity of coffee served and the quality of your water supply.

Daily Cleaning Schedule – Milk flush program using the manufacturers recommended milk cleaning brand, such as Puly Milk Cleaner, then repeat with fresh water. This should take approximately 5 minutes.

Weekly Cleaning Schedule – Internal system clean using the manufactured recommended cleaning tablet such as Jura cleaning tablets or Franke cleaning tablets. This should take approximately 25 minutes.

Monthly Cleaning Schedule – System De-scale using the manufacturers recommended de-scaling agent such as Jura tablets or Franke ready to use liquid. This should take approximately 40 minutes and should be carried out if your machine is plumbed into the water mains with a water filter attached, or water tank model. Most water filters have up to 30% bypass of unfiltered water so lime-scale build up can still build up in your machine.

 

Boiler Inspections

Your commercial coffee machine boiler must by law be examined and certified as safe. It is a legal obligation to have your machine inspected every 14 months (max) this is now been actively enforced by the H.S.E due to a coffee machine exploding in a Sainsbury’s coffee shop in September 2010

As a duty of care to our customers we recommend that your espresso machine is inspected by a specialist inspection and certification organisation. With this in mind we have formed an alliance with a well known insurance company to provide this service.

Relevant excerpt from the document:

Under the Pressure Systems Safety Regulations 2000, a written scheme of examination is required for most pressure systems. Exempted systems are listed in the Regulations. Generally speaking, only very small systems costing under £500 are exempted.

The written scheme should be drawn up (or certified as suitable) by a competent person. (as defined by the Pressure Vessels Regulations 2000) It is the duty of the user of an installed system and the owner of a mobile system to ensure that the scheme has been drawn up. You must not allow your pressure system to be operated (or hired out) until you have a written scheme of examination and ensured that the system has been examined.

The written scheme of examination must cover all protective devices. It must also include every pressure vessel and those parts of pipelines and pipework which, if they fail, may give rise to danger.

The written scheme must specify the nature and frequency of examinations, and include any special measures that may be needed to prepare a system for a safe examination.

The pressure system must be examined in accordance with the written scheme by a competent person.

For fired (heated) pressure systems, such as steam boilers, the written scheme should include an examination of the system when it is cold and stripped down and when it is running under normal conditions.

We can arrange for the inspector and an engineer to attend. The inspection should take approximately 1 1/2 hours. The boiler inspector will provide Written Schemes of Examination and Certificate.
