Deep fryer

A fryer ( deep fryer also Frittierfetterhitzer or electrical ) is a device for frying ( deep frying ) of food products in hot oil or fat, the so-called frying. Deep fryers come in private households, the gastronomy and the industry. While deep fryers work in the home and in restaurants in batch operation (filling, baking, draining ), industrial deep fryers often operate continuously, ie, the crude product is constantly on and the final product is running steadily. In Austria, the fryer is colloquially referred to as a coherer.

Construction

Fryers contain a heater that is located in the bottom plate is of equivalent or an immersion heater as a heating element and a temperature controller with adjustable set point and possibly a safety cut-out, which is to prevent overheating of the frying fat in case of error. Most fryers have a cold zone in which the fat on the bottom stays cooler, and the formation of acrylamide reduced.

Gastronomic devices can be configured as a programmable lifting system - Fryer, whose basket with the fried food can be automatically raise.

Industrial deep fryers are, for example, when pre-frying of French fries used. Also snacks such as potato chips and dry food for dogs and cats are fried. These devices essentially consist of the actual deep fryer, a heat exchanger for heating the cooking oil, a filter, a circulating pump and a tank to fill up the oil circuit. With the product continuously leaves oil the oil circuit (with potato chips about 35 % of the weight of the chips ), so oil must be constantly replenished.

When frying (formerly Fritüre ) the hot oil or fat is referred to in a deep fryer that serves the frying of food. As a secondary meaning, this term also stands for the prepared food that was prepared in this hot oil or grease bath. In German East Belgium is a frying the fast food itself, regardless of whether it is a business in a building or a mobile stand.

Reduction of acrylamide

Fryers are being criticized because at temperatures above 170 ° C increased amounts of acrylamide can occur which may be harmful to health. The relationship between diet and the actual acrylamide content in the body is, however, questionable. In order to reduce the levels of acrylamide, there are special types of fryers. Industrial Vakuumfritteusen, with which, for example potato chips are produced, working with negative pressure and thereby lower frying temperature.
