Description
Technical field
This utility model relates to grain drying device technical field, is specifically related to a kind of high-efficient coal firing hot-air furnaces for foodstuff drying device.
Background technology
It is known that have to dry or dry before the food storage such as Oryza glutinosa, wheat grain, otherwise grain easily occurs that moldy metamorphism phenomenon cannot preserve the long period. Therefore, the storage quality that grain heat-drying processes for ensureing grain is significant, it is all adopt the hot cigarette directly fuel combustion produced to input the grain drying layer to foodstuff drying device due to existing cereal drying technology, grain can be polluted by this mode that directly heats, the hot cigarette temperature that fuel combustion simultaneously produces is uncontrollable, and too high temperature can allow grain Decrepitation Phenomena occur.
Utility model content
The purpose of this utility model is in that to provide a kind of high-efficient coal firing hot-air furnaces for foodstuff drying device, and it can effectively control baking temperature and avoid grain because being there is Decrepitation Phenomena by high-temperature baking; Compared with the direct heating mode of prior art, grain will not be polluted and safe and environment-friendly by indirect hot blast provided by the utility model.
For achieving the above object, this utility model provides following technical scheme:
A kind of high-efficient coal firing hot-air furnaces for foodstuff drying device, including stove framework, described stove framework is provided with the combustor for coal burning and heat exchanger, in described combustor produce hot blast by smoke suction machine introduce to heat exchanger and heating heat exchanger in add heat pipe, the top of described heat exchanger is provided with the first air exhauster, cold air is introduced to adding heat pipe internal recycle in heat exchanger and in heat exchanger by described first air exhauster, the cold air adding heat pipes heat described in warp is introduced to foodstuff drying device by the second air exhauster, described heat exchanger is provided with temperature inductor, the temperature signal sensed is passed to temperature controller system by described temperature inductor, described temperature controller system controls being turned on and off of smoke suction machine by the temperature signal fed back.
Preferably, add heat pipe described in and be provided with the heat exchange fin for increasing hot blast with add heat pipe contact area.
Preferably, the bottom of described stove framework is provided with stove dolly corresponding to the position of combustor.
Preferably, the bottom of described stove framework is provided with roller corresponding to the position of heat exchanger.
Compared with prior art, the beneficial effects of the utility model are:
1, compared with the hot cigarette input directly fuel combustion produced in prior art to foodstuff drying device, in this utility model, the hot blast after heat exchanger heats is indirect hot blast, therefore will not grain be polluted, safety and environmental protection; Temperature controller system can by control smoke suction machine be turned on and off control to dry temperature, thus effectively prevent grain from Decrepitation Phenomena occurring because of high-temperature baking, it is to avoid substantial amounts of foodstuff waste occurs in drying course.
2, the heat pipe that adds in this utility model is provided with heat exchange fin, and it can be effectively increased hot blast and add heat pipe contact area, thus improving heat exchange efficiency and the efficiency of fire coal of heat exchanger.
