Cooking Habits with Deep Fryers That Increase Your Machine’s Lifespan

Maintenance isn’t a job for the day. It is something that you do on a daily basis to ensure that the machine is exposed to healthy use. Some of the recommended cooking habits that you need to use when trying to increase the lifespan on your deep fryer include:

  • Shake off all the ice crystals from any frozen food that you plan on frying. This ensures that water doesn’t get into the oil, which can lead to spluttering and excessive grease accumulation in different parts of the fryer.
  • Refraining from salting the food right above the deep fryer’s oil content can help reduce debris deposition.
  • Filtering the oil content at least once every day, depending on the use, can increase the longevity of the fryer with minimal debris or grease.
  • You need to use the skimmer to ensure that large sediments are pulled out from the oil. This will buy you extra time prior to the oil filtering process.
  • Allow the oil inside the deep fryer to cool to a temperature that is less than the required temperature for cooking. This can help reduce the overall rate with which the oil breaks and decreases in volume.

Common Mistakes Restaurant Owners Make With Deep Fryers

  • Cooking a lot of food at once can lead to a lowering of the oil temperature. This further leads to uneven cooking or sogginess in the food.
  • Do not allow the oil to overheat. This will lead to the food being cooked way too quickly, causing burns on the outside and under cooked content on the inside.
  • Improper use of oil or reuse of the oil way too often can lower the quality of the food produced. So, make sure you change it at regular intervals to maintain the flavor consistency.
  • Do not put out the grease fire with water. It can lead to fire spreading rather quickly.
  • Place the fryer far away from the machines that tend to produce flames on a frequent basis.
  • Refrain from placing wet food inside the fryer. This will lead to water being vaporized, which leads to oil splattering.
