Description
Technical field
The utility model relates to dry materials equipment, the air drying device that particularly a kind of drying program is controlled.Be fit to ordinary material and should not adopt the dry materials of high temperature drying to use.
Background technology
In the prior art; Most drying equipment is material to be carried out dry with the mode of heat drying; As for the relative humidity of how controlling in the drying equipment, accelerate the material water evaporates, improve drying efficiency and but consider seldom; Therefore existing drying equipment ubiquity rate of drying is slow, expends defectives such as heat energy is many.In addition; In existing material, much need kept dry in addition but the unsuitable material that adopts high temperature drying; Like medicinal material, seafood delights etc.; The method commonly used for these material prior aries is to utilize sunshine to dry, even adopt drying box also can only solve with the dry way of long-time lower temperature.These conventional methods not only waste time and energy, power consumption, and be difficult to guarantee dry mass, this is prior art problem extremely to be solved just.
The utility model content
The purpose of the utility model is to provide a kind of drying program controlled air drying device to the problems referred to above of prior art existence.This drying device not only can be accelerated the rate of drying of material, energy efficient, but also can carry out drying according to the different characteristic of different material, guarantee dry mass.
Above-mentioned task realizes by this way: the air drying device that a kind of drying program is controlled; Include a compression hot dry wind preparation facilities, intake valve and control circuit is characterized in that drying shed in addition; Described drying shed is by drying box, whirlwind shower nozzle; Circulation air path, pressure fan and dried humid air separator are formed, and the whirlwind shower nozzle in the drying box is communicated with compression hot dry wind preparation facilities through intake valve; The circulation air path that is provided with connection at the both sides and the top of drying box; Be provided with a supply fan room, blower setting therein in the circulation air path of a side in supply fan room, its air outlet passes top board and is communicated with dried humid air separator, between drying box bottom ventilating opening and supply fan room, is provided with an air-return duct; On the circulation air path of dried humid air separator bottom, be provided with an one-way exhaust valve; Be provided with an one-way exhaust valve in the air-return duct bottom, temperature sensor and humidity sensor are arranged in the supply fan room, on the dividing plate between opposite side circulation air path and the drying box, have several air-guiding holes.
The purpose of the utility model also can take following measure further perfect:
Below dried humid air separator air outlet, also being provided with the cold water pipe that palisade is arranged, the air behind the dried humid air separator of flowing through is further cooled off, quicken gas moisture content and separate.
Be provided with electrothermal tube in the circulation air path above dried humid air separator,, accelerate rate of drying so that use when needing.
The utility model is operation like this and work:
1. for generally can carrying out dry material through the heat drying mode, by following programme-control just can, the material that needs are dry places in the hothouse, connects the whirlwind shower nozzle, pressure fan and dried humid air separator power supply are opened intake valve.The hot dry wind that this moment, compression hot dry wind preparation facilities produced just evenly is sprayed onto in the hothouse through intake valve entering whirlwind shower nozzle material is carried out drying; The air that has moisture content just gets into pressure fan from the ventilating opening and the air-return duct of hothouse bottom; The water of air portion segregation junction that makes band moisture content through dried humid air separator again is outside one-way exhaust valve is discharged; All the other comparatively dry air just get into the circulation air path of opposite side through the circulation air path on hothouse top; Enter in the hothouse through the dividing plate that has many air-guiding holes at last, so circulation is continuous, till material reaches dry the requirement.If need add speed, can connect electrothermal tube power, improve baking temperature.This device just is in negative pressure state in the drying box after starting pressure fan, help the material water evaporates, accelerates rate of drying.
2. should not adopt the dry material of humidification for some, must divide the top layer, could obtain desirable drying effect than shallow-layer, deep layer three phases like the drying of heat sensitivity materials such as Chinese medicine, seafood delights, its dry control procedure is following:
1. set the relative humidity of this material phase I (being superficial drying) earlier; Operation start drying box as usual then; When reaching the rh value of setting, let drying process get into the second stage program, promptly material oozes out (being commonly called as sweating) drying program than shallow-layer moisture content;
2. when the second stage drying program begins, set earlier than lower relative humidity (look the characteristic of material and decide) of phase I, close pressure fan then; Intermittently launch valve and air bleeding valve 1 and 2 of whirlwind shower nozzle; When relative air humidity in the air-return duct is higher than the second stage setting value, three valve openings, and when relative humidity in the air-return duct is reduced to preset definite value; Close three valves simultaneously, this process generally needs about four hours.
3. second drying program finishes the 3rd program that back entering material deep layer moisture content oozes out (deep layer sweating), and at this moment, pressure fan continues to shut down; Air inlet and exhaust valve is also intermittently launched, and through Single-chip Controlling, each is 5 hours; Air inlet and exhaust valve was opened 5 minutes, till the material moisture detection reaches requirement.
The beneficial effect of the utility model is following:
1. because the utility model has used compression type heat dry-air blast preparation facilities; In circulation air path, be provided with pressure fan and dried humid air separator; Not only making the gas that gets in the drying box is xeothermic gas, under the pressure fan effect, make drying box be in negative pressure state again, and dried humid air separator can further be removed the moisture content in the recyclegas; Thereby quickened the rate of drying of material greatly, saved drying time and reduce energy consumption.
2. can find out from the structure and the method for using of the utility model; The utility model not only adapts to the heat drying of ordinary material; The drying that also adapts to heat sensitivity materials such as Chinese medicine, seafood delights fully, solved existing drying equipment be difficult to drier should not heat drying the difficulty of material.
3. because the utility model has been equipped with control circuit commonly used, temperature, humidity and the time of dry thing are realized automatic control, can guarantee the dry mass of material.
