Many dishes that people love are fried. Fried food, like French fries and fried chicken, is
part of our daily lives. Frying makes food crispy. Food with coating like calamari or the Japanese dish, tempura, after being deep fried comes out with a crispy coating contrasting a tender and moist interior.
This is why frying is an important part of the restaurant business. In fact, fast food chains will die out if fried food will be removed from their menu. Around 80% of a restaurant’s revenue comes from fried food. So by hook or by crook, there should be some frying.
Unfortunately, because frying produces odors that can stick to clothes and can be unpleasant to some people, many restaurants and homes need to have ventilation systems before frying. In addition, oil at very high temperatures is highly flammable, so the governments require the businesses to install a fire-suppressing system. All of these together can be expensive, about $20,000 to $30,000, or not possible to install in some buildings. Thankfully, the invention and production of the ventless fryer has made it feasible for many restaurants and homes to fry without guilt.
Ventless models are first of all, more affordable than ventilation systems and hoods. These are also usually smaller than the usual deep fryers. The average size for counter-top types is 2 square feet. Although the capacity is limiting, it is good for tight places and establishments that cannot afford ventilation systems.
Many models are fully automated, self-contained units so that all a person has to do is put the food in and set the controls. The fryer will not start cooking unless all chutes and trays are locked.
Some brands use HEPA-style (high efficiency particulate arrestor) filtration. This type of filter system is commonly used in vacuum cleaners and captures about 99.97% particles larger than 0.3 microns.
One company that produces the ventless fryer is AutoFry. Below are the automated, self-contained, commercial-type fryers they produce. Each uses the Simplifry™ technology that allows multiple programmable pre-sets:
