Abstract

The utility model relates to a gas-phase heat-conduction oil oven for baking food. The utility model is composed of a bottom-layer oil storage chamber, an upper and a lower channels for the oil storage chambers, an upper-layer oil storage chamber, an oil return pipe, a first level gas generating chamber, an overheating gas generating chamber, a gas outlet pipe, and a chimney. Combustion coal is combusted in an oven chamber, and heat transfer oil is gasified in the first level gas generating chamber. The combustion coal then enters the overheating gas generating chamber form the top of the bottom-layer of the oil storage chamber, and enters a row of pipes of the utility model through the gas outlet pipe in the form of heat transfer oil steam which is converted into liquid after releasing heat. The liquid returns the upper-layer oil storage chamber through the oil return pipe, returns the bottom-layer oil storage chamber through the upper and the lower channels for the oil storage chambers, afterwards enters the first level gas generating chamber, and then enters a circulation system through converting into the gas by heated again. The speed of the conduction of the heat is fast through the circulating variation of liquid to gas, and gas to liquid. The utilization rate is high, and the temperature is stable. The utility model is suitable for the baking and the drying of various substances.

Description

A kind of gas phase heat-conducting oil furnace that is used for food-baking

The utility model relates to the food processing roasting plant, relates in particular to a kind of gas phase heat-conducting oil furnace that is used for food-baking.

Roasting plant in existing food (as biscuit, the cake) production and processing, mainly with electrothermal tube as heating element heater, power consumption is big, because aspects such as electricity charge rise cause the baking cost constantly to raise.Though the application of present all kinds of heat-conducting oil furnaces has had large development, the existing gas phase heat-conducting oil furnace ubiquity heating-up time is long, shortcomings such as furnace temperature instability, and the application in food production processing still has the not mature enough problem of technology.

The purpose of this utility model is, overcomes the weak point that prior art exists, and a kind of coal-fired heat utilization efficiency that both can improve is provided, and can make the baking oven quick heating again, the gas phase heat-conducting oil furnace that is used for food-baking of temperature stabilization.

The purpose of this utility model realizes with following technical scheme: the gas phase heat-conducting oil furnace that is used for food-baking described in the utility model is a fuel with the coal, includes body of heater, burner hearth, fire grate, bottom accumulator, accumulator passage, upper strata accumulator, oil return pipe, one-level gas generating chamber, overheated gas generation chamber, escape pipe and chimney are formed up and down.In the food production oven of prior art, electrothermal tube is replaced by the jet chimney of arranging at a certain distance, abbreviate comb here as.There is difference in height at the comb two ends, are convenient to liquid flow.Conduction oil becomes conduction oil steam under the effect of oven endogenous pyrogen in one-level gas generating chamber, conduction oil steam is up along pipeline automatically, flows in comb, discharges heat, becomes conduction oil liquid again, reaches the purpose that makes the oven heat temperature raising.From in appearance, the gas phase heat-conducting oil furnace that is used for food-baking described in the utility model is divided into two parts up and down, and top is phase chamber, and the bottom is a liquid-phase chamber.From the gas-liquid indexing, the outside is oil return pipe, accumulator, and inside is gas generating chamber.The side of one-level gas generating chamber has pipeline to communicate with the side of bottom accumulator, and the top of one-level gas generating chamber has pipeline to communicate with the top of bottom accumulator.Oil return pipe is arranged on the top of body of heater, oil return pipe is arranged on the top of upper strata accumulator specifically, and the upper strata accumulator has pipeline to communicate with the bottom accumulator, as accumulator passage up and down, make the gas-liquid that in oven, refluxes through oil return pipe, along the reverse comb that enters oven of oil returning tube.Conduction oil is drawn in the chimney bottom side by the escape pipe that liquid state becomes behind the gaseous state, can utilize the heat of oven burner hearth fire coal so more fully.When the fired coal combustion in the oven, inside produces conduction oil steam with classification, at first be in one-level gas generating chamber, to gasify, top by the bottom accumulator enters the overheated gas generation chamber, enter within the comb of food baking oven by escape pipe with overheated conduction oil steam, become liquid after the release heat, get back to the upper strata accumulator by oil return pipe, warp accumulator passage is up and down got back to the bottom accumulator, enters one-level gas generating chamber then, form with superheated steam flows in the comb of food baking oven again, after emitting heat, become liquid state, flow back into accumulator again by gaseous state, be heated then and become gaseous state, so form the circulatory system.

Use the gas phase heat-conducting oil furnace that is used for food-baking described in the utility model, through by liquid state to gaseous state and gaseous state circulation change to liquid state, heat conduction velocity is fast, hot utilization rate height, temperature stabilization.Baking or oven dry applicable to various food, grain, starch, chemical industry, medicinal material etc.

Accompanying drawing is the structural representation that is used for the gas phase heat-conducting oil furnace of food-baking described in the utility model.

1-fire grate 2-bottom accumulator 3-is the accumulator passage 4-upper strata accumulator 5-oil return pipe 6-one-level 7-of gas generating chamber overheated gas generation chamber 8-escape pipe 9-chimney up and down

Referring now to accompanying drawing, be described as follows in conjunction with the embodiments: fire grate 1 is arranged on the bottom of burner hearth, and it is same as the prior art that form is set.Around the burner hearth is bottom accumulator 2, and top is one-level gas generating chamber 6.Fire coal is put into the burner hearth internal combustion, and flame is with side baking bottom accumulator 2, above then directly to 6 heating of one-level gas generating chamber, upwards progressively to crossing hot gas generation chamber 7 until the heating of the bottom of chimney 9 in the burner hearth.One-level gas generating chamber 6 and bottom accumulator 2 have pipeline to communicate, and promptly bottom accumulator 2 will ceaselessly become the conduction oil of liquid to 2 supplies of one-level gas generating chamber through the gas that has that comb refluxes.The high-temperature gas that one-level gas generating chamber 6 produces rises to the top of bottom accumulator 2, rise to overheated gas generation chamber 7 through upper pipe again afterwards, in overheated gas generation chamber 7 through the heating again of burner hearth thermal source, become overheated conduction oil steam, enter by escape pipe 8 within the comb of food baking oven, after the comb release heat, conduction oil steam becomes liquid state, get back in the upper strata accumulator 4 by oil return pipe 5 again, warp accumulator passage 3 up and down is back in the bottom accumulator 2, enters one-level gas generating chamber 6 again, becomes gas under the effect of burner hearth heat, so circulation endlessly forms the circulatory system.Because flame passes through from the top of upper strata accumulator 4, thus still have portion gas to produce here, and, furnace temperature is raise by within the reverse comb that enters food baking oven of oil return pipe.Because the conversion rate of liquid gas and gas-liquid is fast, thus quick heating, and temperature stabilization.Because escape pipe 8 is to draw from the inside, bottom side of chimney 9, so the vapor (steam) temperature of discharging is high and stable, both helped making full use of coal-fired heat, be beneficial to the stable of the gas phase heat-conducting oil furnace temperature that is used for food-baking described in the utility model again.
