2 Safety information

MKN appliances comply with the relevant safety standards. However, this does not exclude all possible dangers from arising, e.g. due to improper use.
Therefore, when installing and operating the unit, the operating personnel must be familiar with and observe local regulations, including BGR 111 Working in catering kitchens.
The following safety measures must also be observed:
Hot surfaces, steam and
liquids
Electricity Risk of electric shock
Risk of burns due to hot surfaces
Wear insulated protective gloves during operation.
Allow surfaces to cool before cleaning.
Do not touch the heating elements immediately after operation.
Risk of scalding due to hot steam
Hot fat causes traces of water to evaporate in an explosive manner; dry the unit completely after cleaning.
Risk of scalding due to hot fat
Observe the effective capacity.
Whenever possible, thaw frozen food before deep frying.
Dry foods containing a lot of water before deep frying.
Do not mix frying fats and oils or different kinds of frying fats.
Units with rollers:
-
Only move the unit when the basin is empty.
-
Lock the rollers during operation.
To avoid damaging the electronics, do not operate the unit if the controls are damaged.

3.4 Using frying fat and oil

Frying fat as a food The food being fried absorbs frying fat during frying, e.g. French fries
7-12%, doughnuts 20-25%. The fat is eaten along with the food; this is why frying fat also counts as a food in terms of nutritional physiology.
Suitability for consumption Frying fat must be suitable for consumption, this means that it must be
replaced in good time before it becomes spoiled.
The period of use given by the manufacturer is always decisive. Good frying fat can be used for about 30-40 hours depending on the method of use and the food being fried.
Extending the usable life
of the fat
Used frying fat Do not top up used frying fat with new fat; replace completely instead.
3.5 Recommended frying temperatures and
To determine whether the fat is suitable for consumption, quick tests (e.g. 3M Oil Testing Strips) are available from specialised suppliers.
The fat will stay suitable for consumption for longer by taking the following measures:
Store frying fat cool when not in use
Choose foods for frying that contain only small amounts of water
Use the frying fat for only one type of food.
Do not overheat the fat (160-180 °C is sufficient)
Do not fry breadcrumbed food
Collect used fat in suitable containers and dispose of properly according to the harmful substance ordinances.
