Abstract
A kind of grain drying equipment of fair current crossing current combination, including drying machine and heating system.Drying machine mainly includes grain storage section, level-one concurrent drying section, level-one delay section, two level concurrent drying section, two level delay section, cross-current drying section, grain discharging section, elevator, hot air duct.Heating system major function is to provide the hot wind of high temperature low humidity, can be equipped with oil fired heating systems or heat pump heat distribution system according to environmental aspect；Combination drying equipment has that energy consumption for drying is low, the regulatable technical advantage of drying quality.The drying process parameter such as drying temperature of this drying equipment, dry wind speed and rate of water loss are adjustable.
Description
Technical field
The present invention relates to grain combination drying technical field, more particularly to a kind of grain drying of fair current crossing current combination is set
It is standby.
Background technology
Grain drying final purpose is to reduce moisture content and raising drying quality.It is thus determined that drying process has become crucial skill
Art problem.The technique used in Condition of Grain-Drying Technology at present has the modes such as Multi-stage downstream, multistage crossing current, multistage mixed flow.It is wherein suitable
Stream, which has, may be used the technical advantage that the dried medium of higher temperature is dried, and use crossing current dry when paddy layer thickness is reasonable
It is dry, rate of water loss can be improved；It improves productivity if above two dry technology advantage is combined and can be received and does
The purpose of dry quality.
The heat source of diversified forms can be used in Grain Drying Process, as coal-fired thermal wind furnace, fuel combustion type hot-blast stove and heat pump are equal
Indirectly heat can be carried out to Cryogenic air by way of heat exchange, become after heating the hot-air of high temperature low humidity to grain into
Row thermal dehydration is dried.But by the requirement of environmental protection, coal-fired thermal wind furnace has been restricted, therefore common drying machine heat source
Based on fuel combustion type hot-blast stove and heat pump.Fuel combustion type hot-blast stove is adapted to south and northern environment, and heat pump is because of environment temperature
When relatively low, the thermal efficiency is very low so that can not work in some cases.Therefore the multi-purpose fuel combustion type hot-blast stove in the general north, and
Heat source of the southern multipurpose heat pump as drying machine.
Invention content
The present invention proposes a kind of grain drying equipment of fair current crossing current combination, it is a kind of drying of fair current crossing current combination
The high temperature drying equipment that machine, heating system combine, according to actual conditions using fuel combustion type hot-blast stove or heat pump as drying machine
Heat source, fully-automatic intelligent control, which may be used, in applied widely, drying process can realize a variety of drying process methods.
Particular content of the present invention：
A kind of grain drying equipment of fair current crossing current combination, it is characterised in that：It is fair current crossing current combination drying machine and
The grain drying equipment that heating system is combined, it includes drying machine and heating system；The grain of fair current crossing current combination described in it
Drying equipment is eaten there are one combined drying system and heating system, can make according to actual needs drying machine structure size and
The heat capacity of heating system matches, and is followed successively by from top to bottom：
1 grain storage section, 2 level-one concurrent drying sections, 3 level-one delay sections, 4 two level concurrent drying sections, 5 two level delay sections, 6 crossing currents
Dryer section, 7 grain discharging sections, 8 elevators, 9 hot air ducts, 10 heating systems.
The features and advantages of the invention
A kind of grain drying equipment of fair current crossing current combination, because of it, to have played the technology of concurrent drying and cross-current drying excellent
Gesture, can be contacted, cross-current drying section paddy layer thickness is suitable simultaneously with the higher thermal medium of temperature with grain, be improved dry equal
Even property, and because between concurrent drying section, there is tempering segment structure, therefore can cause water between fair current and cross-current drying section
Divide the concentration of thermal stress avoided in grain diffusion process so that Grain Drying Process rate of drying is uniform, it is dry to effectively reduce
Grain crackle gaining rate after dry, improves drying quality.This equipment has alternating temperature, becomes wind speed and the functions such as rate of drying is adjustable,
Using intelligent automatic control system, drying process parameter is easily controllable, suitable for various grain commodity foods and seed to different dry
The requirement of drying process.
A kind of grain drying equipment of fair current crossing current combination uses the combination that a kind of concurrent drying and cross-current drying are combined
Drying equipment, the equipment can improve the drying quality of commodity food and seed, can effectively improve productivity, reduce drying cost.
Description of the drawings
Fig. 1 is a kind of grain drying equipment of fair current crossing current combination
1 grain storage section, 2 level-one concurrent drying sections, 3 level-one delay sections, 4 two level concurrent drying sections, 5 two level delay sections, 6 crossing currents
Dryer section, 7 grain discharging sections, 8 elevators, 9 hot air ducts, 10 heating systems.
Specific embodiment
A kind of grain drying equipment of fair current crossing current combination as shown in Figure 1, it is by concurrent drying and cross-current drying phase
With reference to grain drying equipment, it include drying machine and heating system；A kind of grain drying of fair current crossing current combination described in it
There are one combination type drying machines and heating systems for equipment, can make the structure size and heating system of drying machine according to actual needs
Heat capacity match：
1 grain storage section, 2 level-one concurrent drying sections, 3 level-one delay sections, 4 two level concurrent drying sections, 5 two level delay sections, 6 crossing currents
Dryer section, 7 grain discharging sections, 8 elevators, 9 hot air ducts, 10 heating systems.
There are one combination type drying machines and heating systems for a kind of grain drying equipment of fair current crossing current combination described in it.For
The hot air duct of hot systems and combination type drying machines is connected.
A kind of course of work of the grain drying equipment of fair current crossing current combination is as follows：
After surrounding air and heating system are by indirect heat exchange, temperature raising humidity reduce become carry it is wet very capable
Dried medium, level-one concurrent drying section 2 and two level concurrent drying section 2 and cross-current drying section 6 through the entrance drying machine of hot air duct 9
Heat exchange is carried out with grain, drying process grain carries out tempering in level-one delay section 3 and two level delay section 5, by dry gentle
Soviet Union's process, dried medium take away the moisture being evaporated from grain, achieve the purpose that reduce grain moisture content, when dry by one
When dry flow does not reach grain final moisture content, grain passes through grain discharging section 7, into elevator 8, enters again from grain storage section 1
Drying tower so that grain enters new round drying process, until grain moisture content is up to standard, grain is discharged drying machine through grain discharging section
Outside, drying process is completed.
According to the difference of application region, a kind of heating system of the grain drying equipment of fair current crossing current combination makes in south
Used time can select heat pump system, and oil fired heating systems can be selected when the north uses.
