How to maintain and clean your commercial deep fryer


Deep fryers are popular appliances used in many restaurants and food service establishments to enhance the flavour and texture of popular dishes. However, failing to clean your fryer regularly can compromise the taste of your dishes. Maintaining and cleaning your deep-fat fryers appropriately is key to ensuring customers have a pleasurable and safe dining experience each time they visit.

Regularly cleaning commercial deep fryers also brings operational advantages, such as energy savings. Carbon build-up on fryer surfaces and coils forces the machines to work harder to heat up. By keeping them clean, you save energy, time, and money. Discover the following deep fryer cleaning tips to maintain equipment longevity and keep customers satisfied.

The importance of regular cleaning and maintenance

Regular cleaning of your professional deep fryer is essential not only for the taste of your fried foods but also for the safety of your customers and staff.

Prevents flavour transfer

Over time, residue from previously fried foods can build up in your deep fryer, affecting the flavour of new items being cooked. This can result in unpleasant flavours and potentially ruin the taste of your dishes. Regular cleaning ensures that there is no flavour transfer between different batches of food, allowing you to maintain consistent and delicious flavours in all your fried dishes.

Extends equipment lifespan

A well-maintained deep fryer will last longer and perform better than one that is neglected. Regular cleaning prevents the buildup of carbon deposits, grease and other debris that can damage the heating elements and other components of the deep fryer. By cleaning your deep fryer regularly, you can extend its lifespan and avoid costly repairs or replacements.

Ensures food safety

Dirty deep fryers harbour lots of bacteria and other pathogens that can contaminate your food and make customers sick. Regular cleaning helps prevent the growth of harmful microorganisms and ensures that your fried foods are safe to eat. By following a strict cleaning schedule, you can maintain high standards of food safety in your kitchen and protect both your customers and staff from foodborne illnesses.

Improves efficiency

A clean deep fryer operates more efficiently than a dirty one, allowing you to save time and energy during cooking. Buildup of grease and debris can hinder heat transfer in the fryer, causing uneven cooking and longer cooking times. Regularly cleaning your deep fryer ensures that it functions at optimal levels, resulting in faster cooking times, lower energy costs and higher productivity in your kitchen.

Enhances food quality

Clean oil produces better-tasting fried foods with a crispier texture and fresher appearance. Dirty oil with leftover food particles can impart unwanted flavours to new batches of food and result in soggy or greasy textures. By regularly filtering and changing oil as well as cleaning the deep fryer itself, you can maintain high-quality standards for all your fried dishes and keep customers coming back for more.

Tips for cleaning your deep fryer

To ensure your deep-fried dishes remain delicious, it's crucial to regularly maintain your commercial deep fryer. Adopting a proper routine for this will make maintenance easier, ensuring a smooth operation. Below are some tips for keeping your restaurant's fryer in top condition.

Daily maintenance

Just like any professional appliance, it’s recommended to clean your deep fryer after it’s been used. It’s not necessary to clean after every use but at least once a day to ensure hygiene. We recommend you clean your deep fryer at the end of the day, so you can easily start preparing fresh food the next morning.

Because frying oil is expensive, it’s also a good cleaning practice to filter your oil so you can reuse it. This can be done by using special filtration machines or simply skimming out crumbs before they burn and contaminate the oil.

For practical cleaning, Maxima’s fryer baskets can be washed in a dishwasher and dried with a soft cloth. Additionally, it’s also best to wipe down your fryer’s exterior with a damp cloth daily.

Thorough deep clean

In addition to daily maintenance, it’s crucial to conduct a thorough deep cleaning of your deep fryer every three to six months. This will ensure the prolonged efficiency of your appliance. Start by draining the oil, then fill the vat with water and a suitable food-safe cleaning agent. Never use aggressive cleaning agents or abrasives. Do not use solvents or petrol-based cleaning agents as these may leave harmful residues or cause damage to the machine.

Heat the mixture in the fryer to a simmer without boiling and use a gentle brush for scrubbing the interior until it's spotless. Do not use a scourer or sharp or pointed objects during cleaning, as this may cause damage to the machine. Afterward, empty and dry the fryer thoroughly.

Tip: You can also clean your deep fryer with dish soap. Prepare a solution of warm water mixed with dishwashing liquid, preferably one infused with lemon due to its superior degreasing capabilities and pleasant aroma. Use a gentle sponge with this mixture to cleanse the internal pan, basket, lid and exterior of your deep-frying appliance. If there is any stubborn food residue, allow it to soak in the solution for a while.

Frequent oil replacement

The importance of changing your fryer's oil regularly cannot be overstated, especially in a commercial setting. Ideally, the oil should be replaced at least twice a week, depending on usage. Indications for an oil change include a burnt smell from heated oil or noticing that the fried food appears darker than usual.

Many of Maxima’s fryers are equipped with a drain tap that makes changing the oil quick and convenient. To change the oil, you only need a large container that you place under the drain tap. Then simply open the tap and let the old oil flow into the container. When the fryer is empty, you can close the tap again. Deep-frying often produces crumbs that sink to the bottom. Maxima’s fryers also feature a removable grid that ensures food residue does not clog the drain.

Use the right oil

Choosing the correct type of oil is critical for deep frying, as not all oils are suitable for high temperatures or specific food types. It’s essential to opt for oils that have a high smoke point for better frying outcomes. Peanut, canola and vegetable oils are ideal for deep frying due to their high smoke points, which exceed 200°C. Typically, deep frying is carried out at temperatures ranging from 170 to 200°C.

When deep frying, especially in high volumes, it's best to avoid clear oils with low smoke points. Oils such as coconut, olive and certain varieties of corn oil have lower smoke points, making them unsuitable for deep frying as they tend to degrade under high heat.

Regular checks and inspections

Keep an eye out for any signs of wear, especially concerning the thermostat and gas pipes in gas-powered models, to guarantee both safety and effectiveness in operations.

Additionally, scheduling an annual professional check-up for your deep fryer is a sensible maintenance strategy to ensure its longevity and performance. Annual maintenance can also help preserve the quality of your food. For detailed inspections or other maintenance services, you can contact Maxima’s technical service for expert assistance.

Regularly cleaning and maintaining your deep fryer is essential for keeping it hygienic and safe to use. It also helps extend its lifespan and prevents costly repairs. Remember to always follow the manufacturer's instructions and use high-quality food-safe cleaning products to guarantee the best results.

Don't forget about the importance of proper frying techniques as well, as it greatly affects the overall quality of your food. Invest time and effort into properly maintaining your deep fryer and you will see the difference in taste and consistency of your fried dishes.
