Abstract
The invention relates to the grain drier technology filed and especially relates to a control method for a grain drier. Grain is dried through circulation mode and drying mode. In this way, the drying effect is good.
Description
Technical field
The present invention relates to crop dryer technical field, particularly relate to a kind of control method of crop dryer.
Background technology
Crop dryer is for drying cereal, but the crop dryer of prior art is all directly carry out drying process, but because the cereal humidity of carrying out drying is not identical, a part of grain dry may be caused not exclusively dry so directly carry out drying, part grain dry is excessive, namely adopts in this way that drying effect is poor.
Summary of the invention
Technical problem to be solved by this invention is: the control method providing the good crop dryer of a kind of drying effect.
The technical scheme that the present invention will adopt is: a kind of control method of crop dryer, and it comprises the following steps:
(1), select automatic mode or timing mode, if select automatic mode, then enter next step; If selection timing mode, then jump to step (7);
(2) circulation moisture content difference, dry moisture content value and hot blast temperature, is set;
(3), enter grain, and enter after grain completes to enter next step;
(4), first control grain to move, and interval X time detecting grain moisture content content, altogether detect Y time, and by repeated detection to Measurement for Grain Moisture Content maximum difference compared with circulation moisture content difference, if the grain moisture content content maximum difference detected is greater than circulation moisture content difference, then enter next step; If the grain moisture content content maximum difference detected is less than circulation moisture content difference, then jump to step (6);
(5), ON cycle pattern, circulating ventilation operation is carried out to grain, then within the A time, detects B grain moisture content content, if B the grain moisture content content maximum difference detected is less than circulation moisture content difference, then enter next step; If B the grain moisture content content maximum difference detected is greater than circulation moisture content difference, then proceed circulation pattern, and within the A time, detect B grain moisture content content again, until B the grain moisture content content maximum difference detected is less than circulation moisture content difference, then enter next step;
(6), open drying mode, hot blast is led to grain and carries out drying process, and every C time detecting grain moisture content content, detect that if continue D grain moisture content content is all less than dry moisture content value, then jump to step (8); If detect, a grain moisture content content is greater than dry moisture content value, then proceed drying, until be consecutively detected D grain moisture content content to be less than dry moisture content value, then jumps to step (8);
(7), set hot blast temperature and drying time, then opening timing drying mode, hot blast is led to grain and carries out drying process, when entering next step after the drying time that the time of drying process reaches setting;
(8), stop drying mode, then put out cereal.
Adopt above method compared with prior art, the present invention has the following advantages: two patterns first can be had selective, such user is more convenient to use, and add circulating ventilation operation in automatic mode, can reduce needing the moisture content difference of dry cereal like this, and then carry out drying process, namely make drying effect better.
As preferably, in described step (2), circulation moisture content difference, dry moisture content value and hot blast temperature unification are set by selected grain variety.Because different grain varieties, circulation moisture content difference, dry moisture content value and hot blast temperature are all different, so directly set grain variety, are so just equivalent to set this three parameters, make user operation get up so convenient.
Detailed description of the invention
Below for detailed description of the invention, the present invention is described further, but the present invention is not limited only to following detailed description of the invention.
A control method for crop dryer, it comprises the following steps:
(1), select automatic mode or timing mode, if select automatic mode, then enter next step; If selection timing mode, then jump to step (7);
(2) circulation moisture content difference, dry moisture content value and hot blast temperature, is set;
(3), enter grain, and enter after grain completes to enter next step;
(4), first control grain to move, and interval X time detecting grain moisture content content, altogether detect Y time, and the Measurement for Grain Moisture Content maximum difference detected Y time is compared with circulation moisture content difference, if the grain moisture content content maximum difference detected is greater than circulation moisture content difference, then enter next step; If the grain moisture content content maximum difference detected is less than circulation moisture content difference, then jump to step (6);
(5), ON cycle pattern, circulating ventilation operation is carried out to grain, then within the A time, detects B grain moisture content content, if B the grain moisture content content maximum difference detected is less than circulation moisture content difference, then enter next step; If B the grain moisture content content maximum difference detected is greater than circulation moisture content difference, then proceed circulation pattern, and within the A time, detect B grain moisture content content again, until B the grain moisture content content maximum difference detected is less than circulation moisture content difference, then enter next step;
(6), open drying mode, hot blast is led to grain and carries out drying process, and every C time detecting grain moisture content content, detect that if continue D grain moisture content content is all less than dry moisture content value, then jump to step (8); If detect, a grain moisture content content is greater than dry moisture content value, then proceed drying, until be consecutively detected D grain moisture content content to be less than dry moisture content value, then jumps to step (8);
(7), set hot blast temperature and drying time, then opening timing drying mode, hot blast is led to grain and carries out drying process, when entering next step after the drying time that the time of drying process reaches setting;
(8), stop drying mode, then put out cereal.
In described step (2), circulation moisture content difference, dry moisture content value and hot blast temperature unification are set by selected grain variety.
If grain variety is paddy, then get X=20 minute, Y=2 time, A=60 minute, B=3 time, C=30 minute, D=3 time.
Claims (2)
1. a control method for crop dryer, is characterized in that, it comprises the following steps:
(1), select automatic mode or timing mode, if select automatic mode, then enter next step; If selection timing mode, then jump to step (7);
(2) circulation moisture content difference, dry moisture content value and hot blast temperature, is set;
(3), enter grain, and enter after grain completes to enter next step;
(4), first control grain to move, and interval X time detecting grain moisture content content, altogether detect Y time, and the Measurement for Grain Moisture Content maximum difference detected Y time is compared with circulation moisture content difference, if the grain moisture content content maximum difference detected is greater than circulation moisture content difference, then enter next step; If the grain moisture content content maximum difference detected is less than circulation moisture content difference, then jump to step (6);
(5), ON cycle pattern, circulating ventilation operation is carried out to grain, then within the A time, detects B grain moisture content content, if B the grain moisture content content maximum difference detected is less than circulation moisture content difference, then enter next step; If B the grain moisture content content maximum difference detected is greater than circulation moisture content difference, then proceed circulation pattern, and within the A time, detect B grain moisture content content again, until B the grain moisture content content maximum difference detected is less than circulation moisture content difference, then enter next step;
