Abstract
The invention discloses the furnace drying method that a kind of microwave can be combined with air, the high-temperature gas that can be provided by microwave and air carries out composite drying.What the present invention was provided with air can combine the method dried using microwave, combine the characteristics of microwave and air can produce high-temperature gas, and with outside cooperation is further dried in internally dry by thing to be dried, largely improves drying efficiency.
Description
Technical field
The invention belongs to microwave drying field, and in particular to the furnace drying method that a kind of microwave can be combined with air.
Background technology
Microwave drying is different from traditional drying mode, and its heat transfer direction is identical with moisture diffusion direction.With traditional drying
Mode is compared, with rate of drying is big, energy-conservation, production efficiency height, uniform drying, clean manufacturing, it is easy realize Automated condtrol and
The advantages of improving product quality, thus be increasingly taken seriously in dry every field.It is external just early in the sixties in last century
Application and theory to microwave drying technology have carried out numerous studies, have been got back further development in recent decades.
Conventional drying process, such as flame, hot blast, steam, electrical heating, are that external heat is dried, surface of material absorbs
After heat, through heat transfer, inside heat leak to material, heat up drying immediately.And microwave drying is then entirely different, it is a kind of
The method of inside heating.Wet stock is in cycle of oscillation extremely short microwave high-frequency electric field, and pole can occur for its internal hydrone
Change and along the direction proper alignment of microwave electric field, the then rapid interaction with high-frequency alternating field direction changes and rotated, and
Violent collision and friction (each second is up to more than one hundred million times) is produced, as a result a part of microwave energy is molecular motion energy, and with
The form of heat is showed, and the temperature of water is raised and is left material, so that material obtains drying.That is, microwave
Into material and after being absorbed, its energy is in material dielectric internal conversion into heat energy.Therefore, microwave drying is to utilize electromagnetic wave
As heating source, dried material sheet as heater a kind of drying mode.
In traditional drying process, to improve rate of drying, elevated external temperatures are needed, increase temperature gradient, but with
Easy produce the scorched outside and underdone inside phenomenon of material.But during using microwave heating, no matter material shapes, heat can uniformly ooze
Thoroughly, and expansion effect can be produced, beneficial to crushing.
China starts late in terms of the application study of microwave drying technology, although achieve many achievements, but microwave is dry
The Applied research fields of dry technology are narrower, and experimental stage or small-scale production stage, composite microwave dry technology are rested on mostly
Research await expanding, not enough, and microwave drying technology is supporting sets for the moment mass-and heat-transfer theoretical research of microwave drying
Standby and instrument development is still needed reinforcement.
The content of the invention
It is an object of the invention in order to overcome above the deficiencies in the prior art and providing a kind of microwave can combine with air
Furnace drying method, by microwave and air can cooperate with raising drying efficiency.
Technical scheme is as follows：
A kind of furnace drying method that microwave can be combined with air, the high-temperature gas that can be provided by microwave and air is combined
Dry.
Further, microwave is first passed through in the furnace drying method that described microwave can be combined with air, drying process and carries out predry
Dry processing, then carries out composite drying by the heat energy of air energy again.
Further, the furnace drying method that described microwave can be combined with air, dries and is carried out in drying box, the transmitting of microwave
Source is arranged on the inwall of drying box.
Further, the furnace drying method that described microwave can be combined with air, the emission source of microwave is arranged at drying box
On top and side wall.
Further, the furnace drying method that described microwave can be combined with air, the high-temperature gas entrance that air can be provided is set
It is placed in the bottom of drying box.
Further, the furnace drying method that described microwave can be combined with air, the frequency of microwave is 800-5000MHz.
Further, the furnace drying method that described microwave can be combined with air, the temperature of high-temperature gas is 60-120 DEG C.
What the present invention was provided with air can combine the method dried using microwave, and combining microwave and air can produce
Cooperation is further dried in the characteristics of high-temperature gas, internally dry and outside by thing to be dried, largely improves drying
Efficiency.
The present invention can adjust the two at any time in actual use using the combination of microwave and air energy drying
Parameter, for the specific drying program of featured configuration of different things to be dried, thus reached rate of drying fast, efficiency high,
Dry the strong effect of completeness.
Embodiment
Embodiment 1
The present embodiment provides the furnace drying method that a kind of utilization microwave can be combined with air, can be provided by microwave and air
High-temperature gas carries out composite drying.In drying process, it can be dried first by microwave, by the moisture inside thing to be dried
Heating comes out, the energy heats air-flow that then can be produced using air, produces high-temperature gas, treats dried object and enter traveling one
Drying is walked, the collaboration of inside and outside drying has been reached, has improved rate of drying.
Above drying process can be carried out in drying property, wherein the emission source of microwave is arranged on to the inside of drying box,
Side wall can be arranged at, top can also be arranged on, can set to realize more preferable microwave drying simultaneously with side wall and top
Effect.The high-temperature gas entrance that air can be provided can be arranged at drying box bottom, can also be arranged at side wall.During microwave drying
Frequency range be 800-5000MHz, the temperature range of the high-temperature gas that air can be produced is 60-120 DEG C, can be to multiple types
The thing to be dried of type is combined formula drying.
Embodiment 2
The present embodiment provides a kind of the specific of the drying Chinese medicinal material that utilization microwave based on embodiment 1 can be combined with air
Implementation, Chinese medicinal material is crushed first or cuts into segment, be placed in drying box, first adjusts microwave frequency and is
1500MHz, is dried 3-5 minutes, after the evaporation of Chinese medicinal material internal steam starts, and the height that temperature is 60 DEG C can be passed through by being passed through air
Wet body, coordinates microwave to be dried, and continues after drying 30-40 minutes, determines medicinal material moisture and is more than 5%, by High Temperature Gas body temperature
