Description
Technical field
The present invention relates to grain dry technical field more particularly to a kind of blended grain drying means.
Background technique
The various cereal agriculturally harvested are intended to carry out removal moisture drying processing, and the purpose of removal moisture drying processing is to reduce
Its internal moisture reduces water content in cereal, reduce water content on the one hand can reduce cereal voluntarily respiration and disappear
Energy consumption；On the other hand avoid moisture content is excessively high from leading to grain germination, mildew.Large-scale grain dry master in the prior art
Crop dryer is used, has the advantages that dewatering time is short, it is high-efficient to be dried, the matter of cereal storage has been effectively ensured
Amount, reduces the probability of Moldy Foodstuff, germination, and to ensuring that it is vital that grain security plays the role of, cereal is dry in recent years
Dry machine is quickly grown, increasingly by the welcome of users.
Existing crop dryer usually intelligence disposably dries a kind of cereal, and in actual production activity, sometimes
Can there is a situation where cereal surprisingly to mix, and if directly selected using color selector in the cereal of dampness
It selects, the effect that color selector is differentiated can be poor.Therefore, a kind of stubborn problem is had become for such grain dry,
In consideration of it, how to provide the blended grain drying means that a kind of drying effect is good, drying efficiency is high is that those skilled in the art need
The technical problem to be solved.
Summary of the invention
For above-mentioned shortcoming in the prior art, that the present invention provides a kind of drying effects is good, drying efficiency is high
Blended grain drying means.
The present invention using following technical scheme in order to solve the above technical problems, realized:
A kind of blended grain drying means is designed, is included the following steps:
Step 1: the blended grain of different-grain diameter size is introduced together into crop dryer, dry by control cereal
The hot gas wind speed size of dry machine swims in cereal in the dryer section of crop dryer, keeps wind speed constant then to control mixing
Residence time of the cereal in crop dryer dryer section is dried；
Step 2: slowly increasing hot gas wind speed, and partial size is successively overflowed from discharge port from as low as big cereal；
Step 3: different packaging bags is selected to pack respectively the cereal of different-grain diameter；
Step 4: the cereal for obtaining Different Package to step 3 carries out color sorting respectively, is just dried, clean later paddy
Object.
Preferably, the crop dryer is batch circulation dryer, and air supply mode is reverse-flow.
Preferably, the discharge port of the batch circulation dryer is arranged in upper-end part of driving.
Preferably, the temperature range that the step 1 is dried is 30-80 DEG C.
Preferably, the partial size ratio of maximum particle diameter cereal and minimum grain size cereal is not more than 5:1 in the blended grain.
Preferably, pre-dried is first carried out for the cereal in the blended grain containing water content greater than 60%.
Preferably, the equipment that the pre-dried uses is cylindrical drier.
Preferably, the temperature range of the pre-dried is 30-80 DEG C.
A kind of blended grain drying means proposed by the present invention, beneficial effect are:
(1) the method for the present invention utilizes lower end air-supply shape creatively using batch circulation dryer come dry mixed cereal
The downward gravity of cereal is offset at upward buoyancy to reach so that cereal is swum in the dryer section of batch circulation dryer
Stablize the purpose of drying；Then it is sequentially increased air quantity again first to overflow the lesser cereal of weight, is overflowed after the cereal of heavier-weight,
It makes full use of the different different features of cereal gravity property to carry out tentatively separated, is tentatively dispensed respectively；Finally to preliminary
Packing carries out color sorting and obtains not only sufficiently drying cereal that is dry but also carrying out color sorting；
(2) the method for the present invention it is simple, can be easy to implement using existing equipment, while drying course conditional is simple,
Be conducive to carry out the cereal mixed sufficiently dry and sort, improves production efficiency, solve and mix in the prior art
The problem that connected valleys object can not be dried simultaneously, is with a wide range of applications.
Detailed description of the invention
The present invention is described in further detail for embodiment in reference to the accompanying drawing, but does not constitute to of the invention
Any restrictions.
Fig. 1 is the flow chart of the method for the present invention.
Specific embodiment
With reference to the attached drawing in the embodiment of the present invention, technical solution in the embodiment of the present invention carries out clear, complete
Ground description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.Based on this
The embodiment of invention, every other implementation obtained by those of ordinary skill in the art without making creative efforts
Example, belongs to protection scope of the present invention.
Embodiment one
Refering to shown in attached drawing 1, a kind of blended grain drying means of the invention includes the following steps:
Step 1: the blended grain of different-grain diameter size is introduced together into crop dryer, dry by control cereal
The hot gas wind speed size of dry machine swims in cereal in the dryer section of crop dryer, keeps wind speed constant then to control mixing
Residence time of the cereal in crop dryer dryer section is dried；
Step 2: slowly increasing hot gas wind speed, and partial size is successively overflowed from discharge port from as low as big cereal；
Step 3: different packaging bags is selected to pack respectively the cereal of different-grain diameter；
Step 4: the cereal for obtaining Different Package to step 3 carries out color sorting respectively, is just dried, clean later paddy
Object.
Specifically, the crop dryer is batch circulation dryer, air supply mode is reverse-flow, the batch
The discharge port of circulation dryer is arranged in upper-end part of driving；The temperature that the step 1 is dried is 80 DEG C, the blended grain
The partial size ratio of middle maximum particle diameter cereal and minimum grain size cereal is 20:1；For being greater than in the blended grain containing water content
60% cereal first carries out pre-dried, and the equipment that the pre-dried uses is cylindrical drier, the predry
The temperature of dry processing is 80 DEG C.
Embodiment two
A specific example is named to illustrate the method for the present invention:
A kind of blended grain drying means of the invention, includes the following steps:
