Description

Fuel-firing gas-firing formula far infrared food drying tunnel

The utility model relates to the food-baking technical field, particularly a kind of fuel-firing gas-firing formula far infrared food drying tunnel that is mainly used in the biscuit baking.

Existing far infrared food baking apparatus, for example, biscuit oven all is to adopt Electric heating, in upper furnace and bottom one row's far infrared electro-thermal tube is housed, and the food such as biscuit on the transmission chain belt that passes from the burner hearth middle part are toasted continuously.Above-mentioned oven energy consumption is big, and heating wire easily blows, and needs frequent blowing out maintenance, and what influence was produced normally carries out.

The purpose of this utility model is to provide a kind of energy-conservation, efficient, simple and reasonable fuel-firing gas-firing formula far infrared food drying tunnel, and this drying tunnel can be a baker as required, also can be formed by several same baker serial connection.

The purpose of this utility model is achieved in that a kind of fuel-firing gas-firing formula far infrared food drying tunnel, comprise body of heater, the burner hearth that bonnet is formed, inboard wall of furnace body is equipped with thermal insulation layer, be provided with a transmission chain belt that vertically runs through burner hearth at the burner hearth middle part, the burner hearth rear portion is provided with moisture exhausting port, the food drying tunnel is made up of at least one baker, be provided with the enclosed burning chamber above in the baker burner hearth, transmitting chain belt, this top, chamber is heat exchanger plate, which is provided with blast pipe, the bottom is the far infrared radiation plate, and combustion chamber one end and burner delivery outlet are connected, have at least a muffler to pass the combustion chamber, be provided with warm-air pipe below transmitting chain belt, its top tube wall is provided with between combustion chamber and inboard wall of burner hearth and forces hot-air channel for evenly being covered with the air-supply plate of wind pushing hole.

When the food drying tunnel was made up of the baker of two or more same structures, its connected mode was serial connection.The above-mentioned hot-air channel that forces is made up of hot-air channel, blast pipe, discharge pipe, axial flow blower, warm-air pipe, drying tunnel, the muffler of top, combustion chamber, and the upper and lower airduct of axial flow blower is contained in hearth outer wall.The cross sectional shape of described heat exchanger plate and far infrared radiation plate is corrugated or triangle or trapezoidal shape.The material of combustion chamber is the heat-resistance stainless steel plate.The far infrared radiation plate is to apply far ultrared paint in its lower section by the heat-resistance stainless steel plate to make.The warm-air pipe material is an aluminium alloy plate, and the wind pushing hole on the air-supply plate is a louvre type.

This food drying tunnel based on fuel difference can adopt oil burner, can also adopt gas burner.During work, food is placed on and transmits on the chain belt, the far infrared radiation plate is to toasting above the food, force hot blast circulation air cooking to be carried out in the food bottom surface from the wind pushing hole on the air-supply plate, far infrared also toasts the food bottom surface by the reflection of aluminium alloy air-supply plate, reinforcement is to the baking ability of food bottom surface, thereby, improve food-baking speed and baking quality.

Compare with the electrothermal food oven, advantage of the present utility model is simple and reasonable, low cost of manufacture; Energy-conservation; Reliable working performance, durable; Simple to operate, production efficiency is high.

By following embodiment the utility model is further elaborated.

Fig. 1 is the utility model structural representation;

Fig. 2 is the A-A cutaway view of Fig. 1.

With reference to Fig. 1, shown in Figure 2, fuel-firing gas-firing formula far infrared food drying tunnel can adopt a baker according to baking food difference, or the identical baker serial connection of above structure forms.Generally speaking, about about 6 meters of the length of single baker for the biscuit drying tunnel, needs more than 30 meters, at this moment, just needs to form with 5 identical baker serial connections of structure.Technical solutions of the utility model and present embodiment all go to describe according to single baker structure.Burner hearth is made up of body of heater 20 and bonnet 18, and inboard wall of furnace body is equipped with thermal insulation layer 6, transmits chain belt 5 and vertically runs through the burner hearth middle part, is provided with enclosed burning chamber 19 above it.This chamber and peripheral bonnet 18 structures in aggregates.In the present embodiment, the cross section that is rectangle, combustion chamber 19 adopts the heat-resistance stainless steel plate to make.Above the combustion chamber 19 is heat exchanger plate 16, is far infrared radiation plate 8 below, and its cross section is corrugated, helps strengthening the rigidity of this plate and increases heat exchange and far-infrared radiation area.19 anterior erecting are equipped with two mufflers 1 in the combustion chamber, and muffler 1 inner chamber and combustion chamber 19 inner chambers are not connected.Bonnet 18 outer walls at respective combustion chamber 19 front and back ends respectively are equipped with a diesel fuel burner 3, and the delivery outlet 2 of burner 3 is connected with combustion chamber 19, and the flame that burner 3 produces sprays in the combustion chamber 19, becomes the thermal source of this baker.Said burner 3 also can be installed in bonnet 18 tops.Be hot-air channel 15 between heat exchanger plate 16 and the bonnet 18, the air that constantly heats in this passage by heat exchanger plate 16 becomes hot blast.On the heat exchanger plate 16 at 19 middle parts, combustion chamber, be welded with a blast pipe 17, the waste gas in the combustion chamber 19 can be discharged outside the baker.The 19 lower plates outside applies far infrared coating 7 and becomes far infrared radiation plate 8 in the combustion chamber.In drying tunnel 4 both sides side plate 21 is housed.Transmit chain belt 5 and below the rectangular heat airduct 11 that aluminium alloy plate is made is housed between the body of heater 20, its upper plate is air-supply plate 9, evenly be covered with wind pushing hole 10 on the air-supply plate 9, in the present embodiment, wind pushing hole 10 adopts the louver fenestra, adopt this structure both can reach the air-supply purpose, can prevent that also the food particle that transmits chain belt 5 from falling in the warm-air pipe 11 by wind pushing hole 10.At the burner hearth lateral wall axial flow blower 13 and blast pipe 14, discharge pipe 12 are housed, by blast pipe 14 axial flow blower 13 air inlets are connected with hot-air channel 15, by discharge pipe 12 axial flow blower 13 air outlets are connected with warm-air pipe 11, like this, under axial flow blower 13 effects, force hot blast circulation at hot-air channel 15, blast pipe 14, discharge pipe 12, warm-air pipe 11, constantly circulate in drying tunnel 4 and the muffler 1.

When being concatenated into the food drying tunnel by two or more bakers, at connection the sealing heat shield is housed, be provided with adjustable moisture exhausting port at this cover top, the moisture that evaporates during with baked goods discharges out of the furnace.

Compare with electrothermal far infrared baker, under same production efficiency condition, this fuel-firing gas-firing formula far infrared food drying tunnel is with energy-conservation more than 1/3.
