Description
Technical field
The utility model belongs to the drying equipment of food processing field, in particular for the drying equipment of stone mill flour.
Background technique
With the promotion of people's quality of the life, stone mill flour, without any additive, is chewed because nutritional ingredient is complete in mouth
Chewiness, it is smooth when not sticking to one's teeth, swallowing the advantages that be concerned about by more and more people, but during stone mill flour processing, due to
Processing infiltration early period cleaning removal of impurities stage grain absorbs a certain amount of moisture, although grain uses low temperature during transportation
Humidity discharging, selection by winnowing wind feed technique carry out humidity discharging drying, and still, still, infiltration still has a small amount of residual in the intraepidermal partial moisture of wheat
It deposits, causes in stone mill cryogrinding process, wheat flour tide point is higher, after the pack processing of rear end, especially with vacuum packet
The wheat flour of dress, be easy to appear selling period shelf life agglomeration, mildew phenomena, directly affect wheat flour the racks store phase and
End product quality, it is therefore necessary to which stone mill flour is dried.
Also there is the drying equipment for flour currently on the market, for example 201220312360.1 bran flour of Chinese patent dries
Dry machine heating device includes auger shell inner wall, exhaust outlet, auger shell outer wall, cavity, head plate, electric heating tube, center auger
And temperature transducer, the technology of the patent disclosure are exactly using in cavity between electric heater for heating auger shell inside and outside wall in fact
Conduction oil, then to flour indirect heating, the moisture of generation is discharged by exhaust outlet, which has the disadvantage that
First is that: the device be bran flour after processing is completed, then be manually transplanted on the drying and heating device, carry out auger
The sublevel segmentation of conveying drying is interrupted drying equipment, does not have the characteristics of same flour milling equipment linkage, continuous start and stop, in wheat bran
During flour is transported to drying heating equipment, there are the loss of flour material and secondary pollution risk, and automation control journey
Spend consecutive production control that is low, being unfavorable for flour processing and drying.
Second is that: the equipment dries heating method using the electric heating tube being set between auger shell inside and outside wall in cavity
Conduction oil is heated, heating location layout is only positioned in auger shell inner wall, seldom a part of auger of lower part
Shell inner wall cavity, dry that the mode of heating relies on is by the auger shell inner wall lower after the thermally conductive oil medium of electric heater for heating
Cavity hot surface is contacted with bran flour, then, by center flood dragon turning effort, forms auger shell cavity hot surface and wheat bran
Heat exchange between flour, entire heat exchanging process is contacted in solid phase, by realizing under the conditions of the flood dragon Stirring of center
, being bound to cause bran flour can not cause part bran flour that can not have sufficiently with auger shell cavity hotlist face contact
Humidity discharging is imitated, to influence drying effect, which in the process of running, also easily forms Local Heat Transfer unevenness and and local material
Coking phenomenon is overheated, to influence bran flour drying course product quality and drying effect.
Third is that: in bran flour drying heating process, especially in the excessive situation of heating device internal material-feeding, in
The operating of heart flood dragon is bound to cause part bran flour as overflow gas vent descends slowly and lightly in drying workshop, bran flour is caused to damage
It loses, the environmentally protective effect in the raw material availability and process of manufacture in drying course is reduced, in addition, the equipment auger
In cavity between shell inside and outside wall, conduction oil joined as heat transferring medium, and conduction oil can generate volume during heating
Expansion is easy influence center flood dragon and runs well, and causes bran flour heating uneven or hot-spot coking phenomenon, Shi Biying
Bran flour quality is rung, causes bran flour coking to lose, reduces raw material availability, and if just for center of serve flood dragon
Often operating, opens up pressure relief opening on auger shell inside and outside wall cavity top, prevents conduction oil expanded by heating, if taking measures not just
When, easily cause conduction oil to overflow in the insulating layer except auger shell outer wall, or cause hot-air overflow hole carry bran
Surface powder is mixed with conduction oil, brings significant loss and equipment safety hidden danger.
Fourth is that: the equipment is in drying heating process, and the waste heat that drying heating operation generates is direct by flowoff gas vent
It is discharged into air, does not take heat source comprehensive reutilization measure, reduce heat source comprehensive reutilization efficiency, it cannot be effective
Mitigate drying heating equipment living load, reduces the comprehensive utilization of energy ability in drying course.
