Problems solved by technology

Existing tunnel furnaces usually use resistance wire or fuel oil for heating; the tunnel furnace using resistance wire not only has slow temperature rise, high energy consumption, but also unstable firepower, resulting in low output of food produced, uneven heating, and bad taste; tunnel furnace using fuel oil The amount of exhaust gas in the furnace is large, which can easily lead to peculiar smell of the product, and the safety factor is low and the energy consumption is large

Abstract

The invention provides a tunnel kiln. The tunnel kiln comprises a charge device, a kiln body and a discharge device, which are disposed in sequence. The kiln body comprises a conveying chain, a lower heating grate, an upper heating grate, a fan and a gas pipe inside. The lower heating grate and the upper heating grate are disposed in parallel inside the kiln body oppositely. The conveying chain is disposed between a lower heating device and an upper heating device. The fan is disposed above the upper heating device or below the lower heating device. The upper heating device and the lower heating device are respectively connected to the gas pipe. The tunnel kiln is simple in structure, low in cost and convenient and safe to use. By the aid of the upper and lower grates inside the tunnel kiln, gas is directly burned in the tunnel kiln to quickly heat up the inside of the kiln. Therefore, production efficiency is improved, productivity is improved, energy resources are saved, and waste gas production is reduced.

Description

technical field [0001] The invention belongs to the field of food production equipment, in particular to a tunnel furnace. Background technique [0002] A tunnel oven is a food processing device used for baking and cooking food such as bread, toast, biscuits, pizza, pies, etc., and generally includes a furnace body, a conveyor belt and heating components installed in the furnace body. When in use, the furnace body reaches a certain temperature through the heating parts, and the heated product is placed on the conveyor belt. When the product passes through the furnace body through the conveyor belt, the product is heated or dried by the high temperature environment inside the skull. Existing tunnel furnaces usually use resistance wire or fuel oil for heating; the tunnel furnace using resistance wire not only has slow temperature rise, high energy consumption, but also unstable firepower, resulting in low output of food produced, uneven heating, and bad taste; tunnel furnace u...
