The specific embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is carried out clear, intactly description, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment of the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the protection domain of the utility model.
To combine accompanying drawing that the utility model embodiment is done to describe in detail further below.
Like Fig. 1 and shown in Figure 2, the process equipment that a kind of oat is plain comprises: stone mill and supply air system; Described stone mill comprises the upper millstone 7 of fixing lower millstone 4, lower millstone 4 rotations relatively and drives the driving mechanism that upper millstone 7 rotates; The lower millstone 4 of stone mill and upper millstone 7 preferably adopt the stone material of natural gas, or at least its contact part with the oat hull raw material be lithotome.The oat element that assurance processes does not contain hazardous substance.
Supply air system comprises blower fan 14, screen pack 11, the drier 10 and air channel 5 that connects successively; Through air channel 5 to lower millstone 4 and upper millstone 7 zones be blown into relative humidity less than 20%, the pure air of 15~25 ℃ of temperature; In figure shown in the arrow, with guarantee indoor relative humidity less than 20% and processing district 6 temperature of 7 of lower millstone 4 and upper millstones be controlled at 20~40 ℃.
Described supply air system also comprises temperature controller and air-conditioning wind air outlet 13; Temperature controller is not expression in the drawings; Temperature controller is used to detect processing district 6 temperature or air channel air themperature; Be blown into cold air through air-conditioning wind air outlet to the air channel when temperature is higher than processing request, with guarantee indoor relative humidity less than 20% and processing district 6 temperature of 7 of lower millstone 4 and upper millstones be controlled at 20~40 ℃.
Lower millstone 4 is fixed on the frame 1, and described driving mechanism is located in the frame, comprises transmission mechanism and vertical shaft 3; Vertical shaft is fixedly connected with the centre bore in 3 upper millstones, 7 districts; Transmission mechanism drives vertical shaft 3 rotations and drives upper millstone 7 rotations.Transmission mechanism comprises motor, decelerator and travelling gear or driving-belt etc.; Certainly also will comprise the device of regulating motor speed or vertical shaft 3 rotating speeds, as adopting frequency control, or to adopt gear-box etc. all are technique known, no longer detail here!
In the course of work, be that the surface adds oat hull raw material 8 at upper millstone 7, its material hole 8 through upper millstone 7 progresses into processing district 6, processes, and finished product is discharged along lower millstone 4 by processing district 6 outward flanges.
Process adds requirement:
The percentage by weight of oat hull raw material water content is less than 13.5%; If in dry area, like areas such as the Inner Mongol, generally the oat hull raw material less than 13.5%, just can meet the processing request of the utility model at the percentage by weight of indoor its water content of storage; As need before processing, carry out drying to the oat hull raw material earlier in humid climates, otherwise, to lump easily in the process, temperature is wayward.
Also require to add the man-hour indoor relative humidity simultaneously less than 20%; Avoid in process the suction of oat hull raw material too much, the quality of influence processing or the operate as normal of processing.
For the processing district temperature that guarantees 7 of nutritive value lower millstone 4 that oat is plain and upper millstones is controlled at 20~40 ℃; Prevent that the too high oat element that makes of Yin Wendu is rotten, destroy its nutrition.Certainly, optimal scheme is that processing district temperature with 77 of lower millstone 4 and upper millstones is controlled at 20~30 ℃.In addition; Here 20~40 ℃ refer to below 40 ℃, and 20~30 ℃ refer to below 30 ℃, also can below 20 ℃; Just be controlled at 20 ℃ of uneconomical natural laws of also having run counter in the reality; Cause the waste of resource, moreover low excessively temperature also can cause the plain condensate steam easily of the oat that processes, the difficult preservation.
In order to guarantee processing district and indoor temperature; The utility model through supply air system to lower millstone 4 and upper millstone 7 zones be blown into relative humidity less than 20%, the pure air of 15~25 ℃ of temperature, with guarantee indoor relative humidity less than 20% and the processing district temperature of 7 of lower millstone 4 and upper millstones be controlled at 20~40 ℃.Here the requirement to pure air is not absolute, can might need temperature lower according to the situation demand of reality, as below 15 ℃, considers it possibly is more than 25 ℃ for economy yet; Certainly best temperature is 20~25 ℃.
The air source of supply air system preferably directly utilizes natural wind, as just can directly adopting dry natural wind in area, the Inner Mongol; Dried then need be carried out to air in the area that has a humid climate at other, and need filter air in the processed food process certainly to be absolutely necessary, and just requires pure air.
The granularity of the oat element that processes is between 80 to 500 orders.Be in order to satisfy the needs of different crowd, it is plain that the adult can digest the oat of granularity below 400~500 orders, and that children can digest the oat of granularity below 200~300 orders is plain, and it is plain that some patients then can only digest the oat of granularity below 80~150 orders.Simultaneously, different ethnic populations' digestion power also is different.Utilize the utility model can process the oat element of granularity between 80 to 500 orders; Best processing scheme is that the plain granularity of the oat that processes is between 100 to 200 orders; Processing is economical, and is applied widely.
Except guaranteeing through above mode the temperature of processing district, the relative rotation speed that changes upper millstone 7 is a most directly mode, the utility model require the relative rotation speed of upper millstone 7 be 200~1000 change/hour.Avoid causing temperature rise too fast because of processing district upper millstone 7 is bigger with the relative linear velocity of lower millstone 4, this rotating speed and different environment, mill have the heat radiation situation of diameter, upper millstone 7 weight and building stones even the decorative pattern of mill that very big relation is arranged; The relative rotation speed that needs to regulate upper millstone 7 according to actual conditions is regulated; For example, the temperature of processing district is too high, then can suitably reduce the relative rotation speed of upper millstone 7, and fricative like this heat has just reduced.Temperature like the processing district is low excessively, then can suitably improve the relative rotation speed of upper millstone 7, can suitably improve output like this.
The mill that with the diameter is 2000mm is an example, the relative rotation speed of upper millstone 7 be 300 change/hour; This moment, processing district upper millstone 7 was about 0.5m/S with the relative linear velocity of lower millstone 4; The weight of mill is about 1000Kg; The temperature of processing district can be controlled at below 35 ℃, and as strengthening the size or the weight of mill, the relative rotation speed that then need reduce upper millstone 7 guarantees the temperature of processing district.
It is thus clear that the plain processing method of oat of employing the utility model can be processed the oat hull raw material under low temperature condition; Kept the plain nutritive value of oat to greatest extent.
This routine accompanying drawing has adopted the mode of principle to express, and concrete implementation structure maybe be different, and a kind of embodiment that the plain process equipment of a kind of oat is merely the plain process equipment of a kind of oat of the utility model does not represent illustrated embodiments.
The above; Be merely the preferable specific embodiment of the utility model; But the protection domain of the utility model is not limited thereto; Any technical staff who is familiar with the present technique field is in the technical scope that the utility model discloses, and the variation that can expect easily or replacement all should be encompassed within the protection domain of the utility model.Therefore, the protection domain of the utility model should be as the criterion with the protection domain of claims.
