Ice Machine Health Check List

Helping your icemaker keep up with demand…

Could your ice maker do with a health check?
The ice experts at Hubbard, who distribute the Scotsman range of ice makers, offer a few tips:

one
Most pubs will have icemakers with air-cooled condensers, which means they’ll have an air filter.  This needs cleaning. If it gets clogged with dust it will make the ice maker less efficient, so you’ll get less ice.

two
Similarly, keep any grills clean and clear of obstructions.
Your machine requires a constant airflow around it to ensure correct operation.

three
Got a warning light on? If your machine has self-diagnostics and it’s telling you what’s wrong, and it’s something you can fix (e.g. the air filter needs
cleaning), then sort it now. If not, don’t wait, get it seen to by your equipment service provider.

four
Make sure you empty, clean and sanitise the storage bin on a
regular, weekly basis. If your machine is fitted with an anti-bacterial system, change the anti-bac bag every month.

five
If the pump has a scale guard, regular cleaning will help prevent scale building up within the water system.

six
Having a maintenance schedule for the components that need regular cleaning will help keep your equipment in peak condition.

seven
Water filters generally need to be changed every six months (more often in some areas) to ensure maximum productivity.  Make sure your filter has been changed within this timescale.

eight
Also check that the ice maker has been descaled and sanitised recently. Again this should be scheduled for every six months or more often in particularly hard water areas.

What’s a Safe Food Storage Temperature?

Recommended Temperature Guide
Please note apart from Blast Chillers & Freezers, all refrigerated storage and chilled display cabinets are holding cabinets, i.e. designed to store or display pre-chilled or pre-frozen foods only. Heated display cabinets are designed to hold pre-heated foods.
Display cabinets are designed for short-term display of foods, after service, chilled food should be moved to a chilled storage cabinet.

Type of Food Recommended Temperature
HOT FOODS 65°C (minimum 63°C)
CHILLED FOODS 3 / 5C (maximum 8°C)
FRESH MEAT -2 / +2°C
FRESH FISH -1 / +1°C *
FROZEN FOODS -18 / -22°C
SOFT SCOOP ICE CREAM -12 / -18°C (depends on type of ice cream)
WRAPPED ICE CREAM -20 / -24°C
CANS & BOTTLED BEVERAGES Personal choice (generally 1 / 10°C)
WHITE WINE Personal choice (generally 4 / 12°C)
RED WINE Personal choice (generally 14 / 20°C)

 

* Only specific cabinets control humidity and are designed to resist corrosion
The above are given for guidance only.

Fridges have a climate class, this tells you the range of ambient room temperature the fridge can operate within.

Climate Class 3 – ambient of 25 °C with 60% RH
Climate Class 4 – ambient of 30 °C with 55% RH
Climate Class 5 – ambient of 40 °C with 40% RH

and

N Class (temperature class) – ambient of +16 °C and +32 °C.
SN Class (extended temperature class) – ambient of +10 °C and +32 °C.
ST Class (sub-tropical class) -ambient of +18 °C and +38 °C.
T Class (Tropical class) – ambient of +18 °C and +43 °C.

What size ice machine do I need?

What size ice machine do I need?
Ice makers are defined by their production capacity per 24 hours and their ice storage capacity. Before choosing your machine use the table below as a guide to calculate how much ice you will need.

Venue – approx recommended ice guide

  • Bar – 1.4 Kg per person
  • Restaurant – 0.8 Kg per person
  • Fast Food Outlet – 0.23 kg per person
  • Catering – 0.4 kg per person
  • Cafeteria – 0.4 kg per person
  • Salad bar – 18 Kg per cubic foot

Do I need a drain pump?
A drain pump is required when the waste services are higher than the drain outlet of the ice machine.  Placing the machine on a stand may allow for gravity drainage.

What water pressure do I need?
For your machine to operate to the best of its ability you’ll need a water pressure of 1bar (14psi) – 6bar (84psi).
Anything less or more than this will adversely affect ice production. If you have low water pressure consider purchasing an external booster pump; if you have high water pressure consider a restrictor valve.

What temperatures do ice makers operate within?
The minimum temperature that an air-cooled ice machine will work at is 10°C; the maximum temperature is 43°C.
For water-cooled models the minimum water temperature is 3°C and the maximum 32°C.

Do ice makers need ventilation to operate?
As a general rule, you should allow 200mm at the rear of the machine and at least 50mm to the sides and top.

Bin Storage

The ice machine will stop creating ice once the bin storage is full – if you have a machine capable of making 24 kgs of ice in 24 hours – and only a 6 kg bin storage – once the bin storage is full the ice machine will stop working until the bin has been emptied.  You may want to store spare ice in the freezer ready for peak times.

Self-contained Ice Machine

Self-contained icemakers incorporate an ice-production system and ice storage bin into one machine. The smallest machine of the range produces 20Kg/24hrs and stores up to 4Kg, while the largest produces up to 155Kg/24hrs and stores up to 65Kg.

Modular Ice Machine

Modular ice systems have a separate production and ice storage unit (or ice bin). Modular ice production volume starts from 90Kg/24hrs and goes up to 1000Kg/24hrs. Ice storage units vary from 100Kg to 350Kg capacity.

 

Must Read if Buying a Back Bar Bottle Cooler

FAQs – Dimensions Always check the bar fridge will fit though your doorways and in to the space required.

BAR2_2
Do you need to build the bottle cooler in? Look for a back bar chiller with a grid at the bottom front. Why? Because the bar fridges have a condenser at the back and this is used to reject heat from within the bottle cooler. This heat must be expelled otherwise the motor will overheat. Grids allow the hot air to escape and these grids can be located on the sides or front of the bar fridge. Side grids or bar coolers with no grids require an air space all the way around to help vent the warm air. Front grids allow the bar cooler to be built in
Door Type Hinged doors take up more space in a confined space. Door seals on sliding doors can become sticky and tear from drink spillages (require regular wiping down)
Displaying Chilled Drinks Bottle coolers are the most visible chilled cabinets in any bar – ensure the product has good illumination to display the contents.
Capacity Check how many bottles or items you ideally need to display, check bottle heights per shelf.
Door Locks Do you require the security of a door lock for when the product is not in use?
Interior If your planning on heavy usage of the product ensure you purchase a cabinet with a heavy duty interior say hammered aluminum rather than plastic.
Shelving Adjustable shelving allows flexibility in adjusting the height/space for alternative product sizes.
Temperature Display Ideal for keeping an eye on the air temperature inside the cabinet
Delivery Do you require the product urgently or can you wait for the standard delivery – give us a call to find out more information.

Looking for an upright Ice Cream freezer?

Upright ice cream frezer

Take a look at the new Mercutus D1-720 upright ice cream freezer designed specifically for storage of 5 litre napoli pans containing either ice cream or gelato. The freezer holds a total of 44 5-litre napoli pans. The D1-720 can either be used for low temperature (-20°C) storage or for tempering. This is where you bring the ice cream up to serving temperature (normally around -15°C).

Ice cream should not be warmed to serving temperature too quickly. the D1-720 is an ideal storage units from which to transfer into your ice cream display at the ideal serving temperature.

The solid door upright freezer is a real alternative to our usual display ice cream freezers.
