“Rule-of-thumb” adv<strong>ice</strong> on ho<br />
suitable to susta<strong>in</strong> the actual<br />
Gourmet <strong>ice</strong>, D<strong>ice</strong> and Half D<strong>ice</strong> <strong>ice</strong>, Nugget <strong>ice</strong>,<br />
Scale <strong>ice</strong>… Each of these different types of <strong>ice</strong> is meant<br />
to meet and fulfil a specific requirement. <strong>The</strong>y are<br />
produced by <strong>in</strong>herently different <strong>ice</strong> mak<strong>in</strong>g mach<strong>in</strong>es.<br />
Other than by type of <strong>ice</strong>, differences may also be found <strong>in</strong><br />
daily output capacity. More importantly, <strong>in</strong> the storage b<strong>in</strong><br />
capacity, directly related to the footpr<strong>in</strong>t and the production<br />
volume of the units.<br />
<strong>The</strong> true parameter that should be followed when<br />
choos<strong>in</strong>g an <strong>ice</strong> mach<strong>in</strong>e is the quantity of <strong>ice</strong> that the<br />
mach<strong>in</strong>e can hold <strong>in</strong> its storage b<strong>in</strong>, which equates to the<br />
actual quantity of <strong>ice</strong> that is available to the operator "here<br />
and now" as well as for the rema<strong>in</strong>der of the even<strong>in</strong>g<br />
hours.<br />
<strong>The</strong> refill capacity of <strong>ice</strong><br />
mach<strong>in</strong>es dur<strong>in</strong>g serv<strong>ice</strong> hours<br />
is <strong>in</strong> fact relatively limited.<br />
Consider that the hourly<br />
output of a medium- small <strong>ice</strong><br />
mach<strong>in</strong>e ranges from 2 kg per<br />
hour for medium-size models,<br />
go<strong>in</strong>g down to 0.8 kg per hour for the smallest units. It is<br />
strongly advisable to verify that the storage b<strong>in</strong> capacity is<br />
such that it will susta<strong>in</strong> your <strong>ice</strong> requirements from the<br />
early-on aperitives through to after-d<strong>in</strong>ner digestives. Some<br />
of the smallest <strong>ice</strong> mach<strong>in</strong>es with<strong>in</strong> the 20 kg of daily<br />
production capacity, <strong>in</strong> fact, feature a storage b<strong>in</strong> capacity<br />
of only 4 kg!<br />
<strong>The</strong> first rule-of-the-thumb is that the storage b<strong>in</strong><br />
capacity should ideally reflect 50% of the mach<strong>in</strong>es<br />
daily production. Keep <strong>in</strong> m<strong>in</strong>d that once the storage b<strong>in</strong><br />
is full, the <strong>ice</strong> mach<strong>in</strong>e produc<strong>in</strong>g <strong>ice</strong>. It will only restart<br />
when <strong>ice</strong> is removed from the storage b<strong>in</strong>. A storage b<strong>in</strong><br />
that is unable to store the "clos<strong>in</strong>g hours production capacity"<br />
of the mach<strong>in</strong>e will therefore limit the daily actual<br />
capacity of the unit, whilst deliver<strong>in</strong>g only a limited amount<br />
of <strong>ice</strong> when the need is at its peak.<br />
In order to serve your customers with the “perfect<br />
dr<strong>in</strong>k” you need crystal-clear, pure, transparent and full<br />
cubes, to avoid “water<strong>in</strong>g down” the dr<strong>in</strong>ks. In detail:<br />
a hollow cube, a "cube with the hole" will offer a larger<br />
heat exchange surface than a massive cube, which <strong>in</strong> turn<br />
will cause the cube to melt quicker. Hollow cubes usually<br />
melt prior to the average consumption time of the dr<strong>in</strong>k.<br />
Very quick cool<strong>in</strong>g of the dr<strong>in</strong>k will therefore occur, as well<br />
as its (premature) warm<strong>in</strong>g up once the <strong>ice</strong> cubes have<br />
melted.<br />
A full cube, on the contrary, will chill the dr<strong>in</strong>k reflect<strong>in</strong>g<br />
the consumption pattern: promptly, but not abruptly,<br />
durably and not prematurely, preserv<strong>in</strong>g the dr<strong>in</strong>k quality<br />
rather than dilut<strong>in</strong>g it.<br />
Massive cubes will last through the dr<strong>in</strong>k and more, for the<br />
enjoyment of those who love chew<strong>in</strong>g on the residual <strong>ice</strong><br />
cubes…<br />
