An electric barbecue machine with simultaneous heating around the circumference

Abstract

The invention relates to an electric roasting machine capable of heating peripherally simultaneously. The electric roasting machine capable of heating peripherally comprises a temperature control circuit, an electric heating element and a machine shell, and is characterized by further comprising a heating unit arranged in the machine shell, a console arranged at one side of the upper part of the exterior of the machine shell, an oil stain collection unit arranged at the lower part of the heating unit in the machine shell, and a gas pumping and discharging unit, wherein the heating unit arranged in the machine shell is provided with at least one column-shaped hollow tubular heating ring; each heating ring is vertically arranged, and the heating rings are communicated in a vertical direction; each heating ring is provided with a roasting basket; upper and lower end openings of the heating rings are sealed and plugged by sheet iron; spaces between the outer sides of the column-shaped hollow tubular heating rings and the upper and lower sheet irons and spaces between the outer side of the column-shaped hollow tubular heating rings and the machine shell are filled with an insulating and heat-insulating material; the oil stain collection unit is arranged at the lower side of the heating unit. The electric roasting machine has the advantages of simple structure, energy conservation, environmental friendliness, conservation of bamboo resources, high roasting efficiency, cleanness in a roasting process and no food pollution during a food roasting process. The electric roasting machine has favorable market prospect.

Description

technical field [0001] The invention relates to the field of barbecue machines, in particular to an electric barbecue machine with simultaneous heating around the circumference. Background technique [0002] Grilled food is a very popular food. There are charcoal grilling machines and electric grilling machines in the grilling machines used in the existing grilled food. But these barbecue machines have a common feature: when heating food, the heat source is always facing the side of the food. Otherwise the food will be cooked on one side and raw on the other, or burnt on one side and not cooked on the other. On the other hand, in the traditional grilling method, except that the heat source is always facing the food, and the heat source is generally under the food, there will inevitably be the following problems: 1. Repeatedly tumbling and roasting food requires additional power consumption, Either install a tumbling mechanism or manually operate continuously, which is tim...

Problems solved by technology

On the other hand, in the traditional grilling method, except that the heat source is always facing the food, and the heat source is generally under the food, there will inevitably be the following problems: 1. Repeatedly tumbling and roasting food requires additional power consumption, Either install a tumbling mechanism or manually operate continuously, which is time-consuming, energy-consuming, complicated structure, and high cost; 2. During the process of repeatedly tumbling and baking food, heat is conducted from the surface of the food to the inside of the food , which makes when the heat on the surface of the food is transferred to a certain depth in the food, the side of the heated food turns back to the heat source. According to the law of heat transfer, the heated side facing away from the heat source must turn to The outside air releases heat, and the speed of heat absorbed in the food to the inside will also be slowed down

This makes the energy not be used effectively, and the grilling speed is slow and time-consuming; 3. The heat sources of all kinds of existing barbecue machines have not been fully and effectively heat-insulated, and the heat sources are either in an open state or in a semi-open state. , energy waste is serious; four, existing various grilling machines, most of the heat sources are below the food, and some have also separated a layer of metal grid between the food and the heat source, which makes the food in the grilling process Water stains and oil stains drip down on the heat source to produce soot and soot that adheres to the food; in addition, the food residue and oil stains on the metal grid are smoked and baked for a long time and stick to the food. Long-term consumption is very easy to cause cancer, which seriously affects food hygiene and human health. good health

This has been confirmed by modern medical science; 5. Most of the existing types of barbecue machines use bamboo sticks when grilling food, which will also cost a lot of bamboo resources.
