Description

Edible plants energy saving baking machine

The utility model belongs to the energy-saving drying device of removing moisture content from fungi plant, is specially adapted to the drying processing of mushroom, mushroom and straw mushroom etc.

At present, Chang Yong similar dryer in the world is to be fuel with diesel oil, kerosene or coal gas basically, is furnished with corresponding temperature detection and automaton, and the temperature control principle mainly is to change the purpose that fuel delivery (coal gas) is realized temperature control.The fine and soft dryer of vertebra of the bavin that Japan too clear agro-industrial machine Co., Ltd. produced in the eighties, oily dual-purpose type is made up of baking oven, indirect heater and electric cabinet.Wherein, the structure of indirect heater and Fig. 1, indirect heater shown in Figure 2 are similar, as the structure of heat exchanger, and with the relative position of burner hearth, electric cabinet, and cleaning chamber, shoot door, hot blast pressure fan, below hot-air mouth, top return air inlet and chimney arranged.But this burner hearth is established an oil oven outward in addition and is communicated with it, though be fuel with the bavin, need be combustion-supporting, and realize the purpose of temperature control by changing fuel delivery with the oil drop fire, hot blast then produces negative pressure by the hot blast pressure fan and it is sent into by the below hot-air mouth carries out drying in the baking oven.When the temperature of hot blast is lower than 4 ℃ of predetermined temperatures, relay power, oil oven oil spout and auto-ignition combustion, when temperature reaches predetermined hot blast temperature, relay outage, the self-extinguishing of oil oven fuel cut-off.If but added bavin too much and during overtemperature, the part bavin firewood burning velocity that slows down then could only be extracted out.In addition, its indirect heater and baking oven are coupled to each other by hot air duct and return air duct for dividing body structure.Its weak point is, use bavin and two kinds of fuel of oil, and it is much expensive that the price of oil is wanted with respect to bavin and coal, is not suitable for being extensive use of in China rural area; In addition, the many oil ovens and the extinguishing device of lighting a fire automatically, cost up; In operating aspect, this machine can not be controlled the state of the many overtemperatures of bavin automatically, in case overtemperature can only manually be taken out firewood, this just requires the strict control of operating personnel to add the bavin amount, this to the dry mass that has the fungi plant of hypersensitivity for hot blast temperature be have dysgenic.And the branch body structure of this machine makes it loosely organized, can not make full use of the heat radiation of heating furnace, reaches energy-conservation effect.

The purpose of this utility model is to avoid above-mentioned weak point of the prior art, and provides a kind of easy and simple to handle, guarantees dry mass again, expends cheaply, and energy savings is suitable for the fungi plant energy saving baking device that use in the rural area.

Drying unit of the present utility model is characterized in that indirect heater (8) is equipped with combustion fan (9) and self closing door (10), and both are by a contactor control.The temperature control principle is to control the burning velocity of bavin (or coal) by changing oxygen-supplying amount, thus the temperature of control hot blast.In the process of drying, bavin (or coal) burns by combustion fan (9) oxygen supply in burner hearth (3), flue gas discharges out of the furnace through heat exchanger (4) pipeline and chimney, be added with guide plate (12) in the burner hearth (3) and make the flue gas smoothness, and the normal temperature air of drying is flow through heat exchanger (4) forcibly with axial-flow type hot blast pressure fan (5) and burner hearth (3) gabarit becomes dry hot-air, enter baking oven from the below hot-air mouth bright fungi plant is carried out drying, the hot blast guide plate (2) of certain angle is equipped with at the hot-air mouth place, and hot blast is evenly distributed.When hot blast temperature has reached the hot blast temperature of the last temperature controller appointment of electric cabinet (15), the contactor energising, combustion fan (9) shuts down automatically, and electromagnet (11) energising, self closing door (10) is opened, fuel ventilates by spontaneous combustion and burns away, and the speed of burning is slowed down, and hot blast temperature no longer rises.When hot blast temperature was lower than predetermined temperature, contactor was stopped power supply, and electromagnet (11) outage, self closing door (10) is closed, and combustion fan (9) restarts, and increases the oxygen-supplying amount of burning, accelerate burning velocity hot blast temperature is risen, thereby reach the purpose of temperature control.In case fuel is added, it is too quickly to burn, and when making hot blast temperature too high, except that automatic control, can also operate flue spanner (13), reduces exhaust smoke level, rapidly burning velocity is slowed down, and guarantees required hot blast temperature.

Advantage of the present utility model: easy and simple to handle, reliable operation, the dry mass height is combustion with bavin or coal, energy savings, simple in structure, cost is low, can not only dry fungi plant, but also can dry many other agricultural byproducts, as medicinal material, tealeaves, capsicum etc.

The drawing of accompanying drawing is described as follows:

Fig. 1, structural representation profile of the present utility model.

Fig. 2, the A-A profile is looked on a structural representation of the present utility model left side.

In Fig. 1, Fig. 2, (1) is baking oven, and (2) are the hot blast guide plate, (3) be burner hearth, (4) are heat exchanger, and (5) are the hot blast pressure fan, (6) be moistureproof window, (7) are the return air door, (8) indirect heater, (9) be combustion fan, (10) are self closing door, and (11) are electromagnet, (12) be guide plate, (13) are the flue spanner, and (14) are the cold-air flap spanner, (15) be electric cabinet, (16) are cleaning chamber, (17) shoot door.

The cold-air flap of indirect heater connects with connecting rod with the return air door, can link, and by cold-air flap spanner (14) control, pulls spanner (14), and cold-air flap is closed, and the return air door is opened simultaneously.In the later stage of dry run, can change the size of cold-air flap and return air door, simultaneously moistureproof window is turned down or contract fully.Can realize hot blast half circulation or interior circulation, make full use of waste gas, the recovery section waste heat, indirect heater and baking oven are integrated, and middle metal partion (metp) does not add insulation material, can make full use of the heat radiation of indirect heater, save warm-air pipe and backwind tube simultaneously, reduce heat consumption; The gabarit of whole device then adopts metal plate holder insulation filler, reduces radiation loss, realizes purpose of energy saving.

The present embodiment advantage: compact conformation, province's material, be easy to make, cost is lower, and good energy-conserving effect is particularly suitable for the rural area self-employed farmer and uses, and also is suitable for big farm and uses.
