Abstract
The invention discloses an air heater in a food baking oven. The air heater comprises a baking oven, a heat exchange tube, a fan, and a burner. The heat exchange tube and the fan are disposed in the baking oven. The burner is disposed outside the air heater. The baking oven is provided with an air inlet and an air outlet. The heat exchange tube comprises a heating segment, a radiating segment and a tail gas segment. The heating segment is a linear tube, and one end of the heating segment is communicated with the air inlet. The radiating segment is a bend, and one end of the radiating segment is communicated with the other end of the heating segment. The other end of the heating segment is in transitional communication with one end of a tail gas tube. The tail gas tube is also a bend, and the other end of the tail gas tube is communicated with the air outlet of the baking oven. A nozzle of the burner is disposed inside the heating segment. The fan is disposed on the side wall of the baking oven. Heat exchange efficiency of the heat exchange tube can be improved, tail gas is exhausted from the baking oven, and safety and sanitation of food can be guaranteed.
Description
Technical field
The present invention relates to the food baking equipment field, relate in particular to the hot-blast stove field in the curer.
Background technology
Hot-blast stove is the important component part of curer, and being used for provides baked goods required heat energy, and its critical piece is combustor and heat-exchange tube.Heat-exchange tube is generally the U-shaped structure in the present hot-blast stove, and the heat-exchange tube length of this structure is shorter so that in the pipe less, the heat of the contact area of the air in heat and the curer resident time in heat-exchange tube also shorter, rate of heat exchange is lower; Simultaneously the tail end in the heat-exchange tube directly with the curer internal communication, tail gas is understood direct contact food, does not meet environmental protection and hygienic requirements.
Summary of the invention
The problem that the applicant is low for above-mentioned existing hot-blast stove rate of heat exchange, the direct contact food of tail gas does not meet hygienic requirements, carry out Improvement, the hot-blast stove that uses in the another kind of food baking case is provided, thereby improve the rate of heat exchange of heat-exchange tube, simultaneously tail gas is discharged curer, guarantee the safety and sanitation of food.
Technical scheme of the present invention is as follows:
The hot-blast stove that uses in a kind of food baking case comprises curer and is installed on heat-exchange tube in the curer and fan is installed on outside combustor in addition; Offer air intake vent and air outlet on the described curer; Described heat-exchange tube comprises bringing-up section, radiating segment and tail gas section, and described bringing-up section is straight tube, and the above air intake vent of one end and curer is communicated with; Described radiating segment is bend pipe, and the one end is communicated with the other end transition of described bringing-up section, and the described radiating segment other end is communicated with an end transition of described offgas duct; Described offgas duct is bend pipe, and the above air outlet of its other end and curer is communicated with; It is inner that the shower nozzle of described combustor is installed in described bringing-up section; Fan assembly is on the sidewall of curer.
Its further technical scheme is:
Described radiating segment is L shaped bend pipe, and described tail gas section is U-bend; Described bringing-up section, radiating segment and tail gas section are distributed in around the described fan, and connection surrounds back-shaped heat-exchange tube;
The diameter of described offgas duct is less than the diameter of described bringing-up section and radiating segment;
The outer end of described bringing-up section is connected in described air intake vent by flange, and the outer end of described offgas duct is connected in described air outlet by flange.
Beneficial effect of the present invention is:
Heat-exchange tube is back-shaped layout around fan, has increased the length of heat-exchange tube in hot-blast stove, thereby has increased the exchange area of heat and air, improves rate of heat exchange; Simultaneously the diameter of tail gas section is less than the diameter of bringing-up section and radiating segment so that heat can be in radiating segment the resident longer time, also can improve rate of heat exchange; The end of tail gas section is connected in the air outlet of curer, and tail gas is sent curer, thereby avoids the tail gas contact food, guarantees food safety and sanitation.
Description of drawings
Fig. 1 is that master of the present invention looks, the bringing-up section broken section.
Fig. 2 is the stereogram of heat-exchange tube of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figure 1, the present invention includes curer 1, heat-exchange tube 2, fan 3 and combustor 6.The side of curer 1 and end face offer respectively air intake vent and air outlet; Heat-exchange tube 2 is installed in the curer 1, comprises bringing-up section 2-1, radiating segment 2-2 and tail gas section 2-3; Bringing-up section 2-1 is straight tube, and the one end is communicated with curer 1 the above air intake vent by flange 5; Radiating segment 2-2 is L shaped bend pipe, and the one end is communicated with the other end transition of bringing-up section 2-1, and the other end of radiating segment 2-2 is communicated with the end transition of offgas duct 2-3; Offgas duct 2-3 is U-bend, and its other end is communicated with curer 1 the above air outlet by flange 7.Blast pipe 8 is installed in the outside of described air outlet, is used for combustion gas.Combustor 6 is installed on the outside of curer 1, and the shower nozzle of combustor 6 is installed in the bringing-up section 2-1; Returning apparatus has fan 3 on the inwall of curer 1.
In order to increase the residence time of heat in hot-blast stove, heat-exchange tube among the embodiment has been taked two measures: the one, and bringing-up section 2-1, radiating segment 2-2 and tail gas section 2-3 are distributed in around the fan 3, connection surrounds back-shaped heat-exchange tube 2, thereby increases the length of the heat-exchange tube 2 in the hot-blast stove; The 2nd, the diameter of offgas duct 2-3 is less than the diameter of bringing-up section 2-1 and radiating segment 2-2, thus the prolongation time of staying of heat in hot-blast stove, the rate of heat exchange of raising heat energy.
During use, the combustion heat that combustor 6 produces enters among the bringing-up section 2-1 by shower nozzle 4; Heat among the radiating segment 2-2 is by the air generation heat exchange in metal pipe-wall and the hot-blast stove, and fan 3 can be accelerated the air circulation in the curer 1, thereby the temperature in the curer 1 is evenly risen; Tail gas is discharged from tail gas section 2-3 and blast pipe 8, not can with curer 1 in Food Contact, guarantee quality and the safe and sanitary of food.
Above description is explanation of the invention, is not limitation of the present invention, and limited range of the present invention is referring to claim.In the situation that without prejudice to basic structure of the present invention, the present invention can do any type of modification.
