A kind of fire pipe for food baking

Abstract

The invention discloses a flame jet tube for food baking. The flame jet tube comprises a cylinder, an end cover, an airway tube, an exhaust tube and a plurality of flame guide tubes; a plurality of flame jet holes extending along the axial direction of the cylinder are formed in the peripheral wall of the cylinder; the end cover is rotatably arranged on the opening of the cylinder, and is hermetically matched with the opening of the cylinder; the end cover is connected with the airway tube through an airflow regulating mechanism; one end of the airway tube is closed, hermetically penetrates through the end cover, and extends into the cylinder; the other end of the airway tube extends to the outside from the interior of the end cover; one end of each flame guide tube is detachably and hermetically inserted into the tube wall of the airway tube; the other end of each flame guide tube extends to the outside of the cylinder from the interior of the corresponding flame jet hole; a corresponding movable tube telescopically sheathes the other end of each flame guide tube; a plurality of air inlets distributed at intervals are formed in the side wall of the cylinder; the other end of the exhaust tube hermetically penetrates through the end cover. According to the flame jet tube disclosed by the invention, a jet flame can be continuously maintained at a set size for a long service life, thus, control on the good baking quality is facilitated.

Description

technical field [0001] The invention relates to a heating device for food baking, in particular to a food baking fire spray tube. Background technique [0002] Food baking (such as cake baking) is generally carried out in a tunnel furnace, which needs to be equipped with a heating tube or a flame-throwing tube to generate high temperature. Generally, the tunnel furnace has a large volume, and the heating tubes or flame-injection tubes are arranged at intervals on the tunnel furnace along the length direction of the tunnel furnace, and the heating tubes or flame-injection tubes are arranged above the food. Therefore, a large amount of mixed gas needs to be introduced into the fire pipe to ensure that the food is fully heated. Roasted at high temperature, the material is prone to aging and becomes brittle, which reduces the service life, thereby changing the height and uniformity of the fire-breathing flame. If it is replaced, it needs to be replaced as a whole, which is cost...

Problems solved by technology

Generally, the tunnel furnace has a large volume, and the heating tubes or flame-injection tubes are arranged at intervals on the tunnel furnace along the length direction of the tunnel furnace, and the heating tubes or flame-injection tubes are arranged above the food. Therefore, a large amount of mixed gas needs to be introduced into the fire pipe to ensure that the food is fully heated. Roasted at high temperature, the material is prone to aging and becomes brittle, which reduces the life span, thus changing the height and uniformity of the fire-breathing flame. If it is replaced, it needs to be replaced as a whole, which is costly and is not conducive to controlling the quality of food baking.

In addition, after the food is baked, a large amount of moisture will generally be generated, which will absorb part of the heat, resulting in a decrease in the control over the heating temperature of the food, and ultimately resulting in a decrease in the quality of the food baked.
