Description
Technical field
The present invention relates to rice technical field of drying, more particularly to a kind of energy-saving rice drying method.
Background technology
Now due to Changes in weather is variable and uses the limitation of land area per capita, many large-scale meter Ye companies, big
Machine is all have selected in rice processing procedure to dehydrate, rather than traditional Exposure to Sunlight.
The content of the invention
Based on technical problem existing for background technology, the present invention proposes a kind of energy-saving rice drying method.
A kind of energy-saving rice drying method proposed by the present invention, comprises the following steps：
S1, paving are in rice to be dried；
S2, hot-air is obtained, and drive hot-air to be circulated in the sealed pathway by rice to be dried；
S3, hot-air is dried on hot-air circulating path processing and heat supplement.
Preferably, step S2 also includes：In hot-air cyclic process, upset stirring is carried out to rice.
Preferably, in step S3, in step S3, along hot-air flow direction, it is in region to enter rice paving in hot-air
Transition section on to hot-air carry out heat supplement, hot-air outflow rice paving in region transition section on to hot-air
Processing is dried.
Preferably, rice paving is 1/4 to the 1/2 of hot-air circulating path length in the road section length in region.
Preferably, in step S3, it is to the withering mode of hot-air：Driving hot-air is by being arranged on circulation
Circulating path is returned after moisture adsorption layer outside path.
Preferably, in step S3, it is to the withering mode of hot-air：Detect hot-air humidity on circulating path
And compared with humidity threshold, according to comparative result, the drying process of hot-air is controlled to work.
Preferably, in step S3, the mode that heat supplement is carried out to hot-air is：It is in region to enter rice paving in hot-air
Transition section on detect air themperature and compared with default temperature threshold, according to comparative result, control the heat of hot-air
Supplement work.
In the present invention, by step S2 with by hot-air to band dried rice be dehydrated.Hot-air is advantageous to improve
Rice temperature, so as to improve the water evaporation rate in rice；And hot-air circulates in sealed pathway, advantageously reduce
Heat scatters and disappears, and improves heating efficiency.
In step S3, processing and heat supplement are dried to hot-air, hot-air can be avoided because humidity increases and temperature
Degree reduces the dehydrating effect for rice, so as to improve rice drying efficiency and quality.
In the present invention, along hot-air flow direction, enter in hot-air on transition section of the rice paving in region to heat
Air carries out heat supplement, hot-air is dried processing on transition section of the hot-air outflow rice paving in region.Such as
This, advantageously ensures that the region that paving is in rice to be dried is temperature highest region on hot-air circulating path, to improve to big
The dehydrating effect of rice；And it is in region that can flow out the paving of rice to be dried in hot-air, in hot-air during water content highest pair
Processing is dried in hot-air, avoids the Water vapor condensation in hot-air, so as to improve hot-air drying process effect.
Brief description of the drawings
Fig. 1 is a kind of energy-saving rice drying method flow chart proposed by the present invention.
Embodiment
A kind of reference picture 1, energy-saving rice drying method proposed by the present invention, comprises the following steps.
S1, paving are in rice to be dried.
S2, hot-air is obtained, and drive hot-air to be circulated in the sealed pathway by rice to be dried, to pass through
Hot-air is dehydrated to band dried rice.In this step, hot-air is advantageous to improve rice temperature, so as to improve in rice
Water evaporation rate；And hot-air circulates in sealed pathway, advantageously reduce heat and scatter and disappear, improve Btu utilization effect
Rate.
In present embodiment, step S2 also includes：In hot-air cyclic process, upset stirring is carried out to rice, to protect
It is uniform to demonstrate,prove rice dehydration.When it is implemented, agitating device or turning device pair can be set in region in the paving of rice to be dried
Rice is stirred.
S3, hot-air is dried on hot-air circulating path processing and heat supplement.Specifically, in this step,
Along hot-air flow direction, enter in hot-air on transition section of the rice paving in region and heat supplement carried out to hot-air,
Hot-air is dried processing on transition section of the hot-air outflow rice paving in region.In this way, advantageously ensure that paving is in
The region of rice to be dried is temperature highest region on hot-air circulating path, to improve the dehydrating effect to rice；And
It is in region that the paving of rice to be dried, which can be flowed out, in hot-air, hot-air is dried place during water content highest in hot-air
Reason, avoids the Water vapor condensation in hot-air, so as to improve hot-air drying process effect.In this step, hot-air is carried out
Drying process and heat supplement, hot-air can be avoided to increase the dehydrating effect with temperature reduction for rice due to humidity, so as to
Improve rice drying efficiency and quality.
In present embodiment, rice paving is 1/4 to the 1/2 of hot-air circulating path length in the road section length in region.Such as
This, can both ensure area of the rice paving in region, and improve hot-air utilization ratio；Hot-air can be avoided to leave again to be dried
In being heated at once behind region, aqueous hot-air rapid expansion is back to rice paving to be dried and done in region reduction air rice paving
Dry effect.
In present embodiment step S3, it is to the withering mode of hot-air：Detect hot-air on circulating path
Humidity and compared with humidity threshold, when air humidity is more than or equal to humidity threshold, hot-air is dried processing work.
In step S3, it is to the withering mode of hot-air：Driving hot-air is inhaled by the moisture being arranged on outside circulating path
Circulating path is returned to after attached layer, in this way, the moisture in hot-air is retained by moisture adsorption layer.
In present embodiment step S3, the mode that heat supplement is carried out to hot-air is：Entering rice paving in hot-air is in
Air themperature is detected on the transition section in region and compared with default temperature threshold, when air themperature is less than or equal to temperature
Threshold value, carry out the heat supplement work of hot-air.Specifically, can be by setting heater to heat air.
The foregoing is only a preferred embodiment of the present invention, but protection scope of the present invention be not limited thereto,
Any one skilled in the art the invention discloses technical scope in, technique according to the invention scheme and its
Inventive concept is subject to equivalent substitution or change, should all be included within the scope of the present invention.
