Description
Technical field
The present invention relates to crop dryer technical field, more particularly to a kind of control method of crop dryer.
Background technology
Crop dryer is for cereal to be dried, but the crop dryer of prior art is directly to carry out Drying process, but because the cereal humidity being dried is differed, so being directly dried, a part may be caused Grain dry is dried not exclusively, and excessively, i.e., drying effect is poor in this way for a part of grain dry.
The content of the invention
The technical problems to be solved by the invention are：A kind of controlling party of the preferable crop dryer of drying effect is provided Method.
Present invention technical scheme to be taken is：A kind of control method of crop dryer, it is comprised the following steps：
（1）, selection automatic mode or timing mode, if selection automatic mode, into next step；If selection timing mould Formula, then jump to step（7）；
（2）, setting circulation moisture content difference, dry moisture content value and hot blast temperature；
（3）, enter grain, and enter after the completion of grain to enter next step；
（4）, control grain movement first, and be spaced grain moisture content content of X time detectings, detect Y times altogether, and And by repeated detection to Measurement for Grain Moisture Content maximum difference with circulate moisture content difference compared with, if the grain moisture content content for detecting Maximum difference is more than circulation moisture content difference, then into next step；If the grain moisture content content maximum difference for detecting is less than circulation Moisture content difference, then jump to step（6）；
（5）, ON cycle pattern, ventilation operation is circulated to grain, then within the A times detect B grain moisture content Content, if the B grain moisture content content maximum difference for detecting is less than circulation moisture content difference, into next step；If detecting B grain moisture content content maximum difference more than circulation moisture content difference, then proceed circulation pattern, and again within the A times B grain moisture content content of detection, until the B grain moisture content content maximum difference for detecting is less than circulation moisture content difference, then enters Enter next step；
（6）, open drying mode, operation is dried to the logical hot blast of grain, and every grain water of C time detectings Part content, moisture content value is dried if being continuously detected D grain moisture content content and being respectively less than, and jumps to step（8）；If detecting one Secondary grain moisture content content then proceeds drying more than moisture content value is dried, and is less than until being consecutively detected D grain moisture content content Moisture content value is dried, then jumps to step（8）；
（7）, setting hot blast temperature and drying time, be then turned on timing drying mode, the logical hot blast of grain is done Dry operation, enters next step after the time of drying process the drying time of setting is reached；
（8）, stop drying mode, then put out cereal.
Using above method compared with prior art, the present invention has advantages below：There can be two patterns first for choosing Select, such user is more convenient to use, and circulating ventilation operation is increased in automatic mode, will can so need dry The moisture content difference of dry cereal is reduced, and operation is then dried again, that is, cause that drying effect is preferable.
Preferably, the step（2）Middle circulation moisture content difference, moisture content value and hot blast temperature unification are dried by selected Grain variety is set.Because different grain varieties, circulate moisture content difference, dry moisture content value and hot blast temperature not Equally, so directly setting grain variety, thus equivalent to setting these three parameters, so that user operates more Plus it is convenient.
Specific embodiment
Below for specific embodiment is described further to the present invention, but the present invention is not limited only to implement in detail below Mode.
A kind of control method of crop dryer, it is comprised the following steps：
（1）, selection automatic mode or timing mode, if selection automatic mode, into next step；If selection timing mould Formula, then jump to step（7）；
（2）, setting circulation moisture content difference, dry moisture content value and hot blast temperature；
（3）, enter grain, and enter after the completion of grain to enter next step；
（4）, control grain movement first, and be spaced grain moisture content content of X time detectings, detect Y times altogether, and And the Measurement for Grain Moisture Content maximum difference for detecting Y times is compared with moisture content difference is circulated, if the grain moisture content content for detecting Maximum difference is more than circulation moisture content difference, then into next step；If the grain moisture content content maximum difference for detecting is less than circulation Moisture content difference, then jump to step（6）；
（5）, ON cycle pattern, ventilation operation is circulated to grain, then within the A times detect B grain moisture content Content, if the B grain moisture content content maximum difference for detecting is less than circulation moisture content difference, into next step；If detecting B grain moisture content content maximum difference more than circulation moisture content difference, then proceed circulation pattern, and again within the A times B grain moisture content content of detection, until the B grain moisture content content maximum difference for detecting is less than circulation moisture content difference, then enters Enter next step；
（6）, open drying mode, operation is dried to the logical hot blast of grain, and every grain water of C time detectings Part content, moisture content value is dried if being continuously detected D grain moisture content content and being respectively less than, and jumps to step（8）；If detecting one Secondary grain moisture content content then proceeds drying more than moisture content value is dried, and is less than until being consecutively detected D grain moisture content content Moisture content value is dried, then jumps to step（8）；
（7）, setting hot blast temperature and drying time, be then turned on timing drying mode, the logical hot blast of grain is done Dry operation, enters next step after the time of drying process the drying time of setting is reached；
（8）, stop drying mode, then put out cereal.
The step（2）It is middle to circulate moisture content difference, dry moisture content value and hot blast temperature unification by selecting grain variety To be set.
If grain variety is paddy, take X=20 minutes, Y=2 times, A=60 minutes, B=3 times, C=30 minutes, D=3 times.
