Detailed description of the invention
Embodiment one
The multifunction microwave of the present embodiment-deep fat combination freeze drying equipment as shown in Figure 1 to Figure 3, including the horizontal setting cylindric deep fat dry storehouse 10 in frame 2 and microwave dry storehouse 3.One end of deep fat dry storehouse 10 is provided with material door, the other end and water catching bin 4 disjunctor.One end of microwave dry storehouse 3 is provided with microwave door, and the other end connects with deep fat dry storehouse 10 by shielding the adapter of stream plate 15 equipped with sieve aperture.Shielding stream plate 15 is to have round-meshed sieve plate, steam can be allowed freely to pass through, simultaneously shield microwaves, prevents being leaked into deep fat dry storehouse and causes harmful distillation.Water catching bin 4 is built with coil pipe water vessel 4-1, and its bulkhead is connected with the sliding vane rotary vacuum pump 1 being placed in bottom frame 2.One end of coil pipe by catch waterpipe and bottom frame the compressor 14 of 2 be connected with external forced air cooler 4-3 one end, the other end of coil pipe is connected by the other end of expansion valve 4-2 and forced air cooler 4-3, and composition refrigeration catches water circulation system.Deep fat dry storehouse 10 circulates, with deep fat oil storage tank 9, the Multi-layer warming plate 11 connected by oil transfer pump built with inside, is mounted with the electric heating tube as heater in thermal oil circulation pipeline.It is mounted with the heat-conducting metal aluminum charging tray 12 being positioned on LOAD CELLS 13 in each layer heating plate 11 respectively, is therefore easy to understand its aqueous situation of change at any time.The surrounding wall of microwave dry storehouse 3 is distributed six microwave generators 7 radially disposed, four, top is divided into two groups, respectively axially spaced-apart, be angularly positioned at 1:30 ' and the 10:30 ' orientation corresponding to clock, two, bottom be axially located upper axial interval middle, be angularly positioned at corresponding to clock 4:30 ' and 7:30 ' orientation, so make even microwave distribution in storehouse.Disposing three layered material dishes 6 on bin 5 in storehouse, top is equipped with weighing system 8.
The equipment of the present embodiment can select microwave or deep fat single lyophilization mode according to material characteristic, it is possible to selects combined drying mode.When individually using deep fat vacuum lyophilization, first pre-freeze material sorted, clean, cutting, the pre-treatment such as sabot so that being attached to material surface, the original shape that this makes it possible to guarantee material keeps good in freeze-drying process uniform moisture；Then to less than-40 DEG C, moisture is made to become the ice of solid-state wet stock pre-freeze in freezer；When material pre-freeze process draws to an end, opening condenser fan and water catching bin electromagnetic valve, whole equipment is freezed by rear compressor of opening the most simultaneously；After catching waterpipe temperature extremely more than-50 DEG C, opening vacuum pump, the vacuum that whole equipment is evacuated in the limit state of vacuum pump, i.e. vacuum instrumentation display is held essentially constant, and makes ice directly rise Huawei's steam；Sublimation process to absorb heat, and therefore, opens pipeline pump, makes oil circulation flowing；Automatic or manual mode of heating, unlatching deep fat is selected to add heat pipe and material is carried out zone heating；For obtaining more preferable freeze-dried products quality, the predetermined temperature gradient of zone heating should be not excessive, is typically taken as 5, will be set on the temperature data that temperature sensor detects 5 DEG C by preset temperature；Owing to the error of control system is at ± 1 DEG C, when temperature of charge exceedes preset temperature 1 DEG C, control system is automatically switched off deep fat and adds heat pipe, and temperature of charge will little by little lower；When temperature of charge is less than preset temperature 1 DEG C, control system is automatically switched off deep fat and adds heat pipe, and temperature of charge will little by little rise；Maintain each preset temperature drying time of about 2 hours, the most just preset temperature can be promoted 5 DEG C, until temperature sensor detection catch waterpipe temperature basically identical with temperature of charge time, lyophilizing process terminates；Close successively and add heat pipe, pipeline pump, vacuum pump, compressor, carry out defrosting process；Close air-cooled condenser blower fan after 30 minutes, carry out drainage sunk well.When individually using microwave vacuum freeze to be dried, operating process is substantially similar with when individually using deep fat vacuum lyophilization, difference is after catching waterpipe temperature extremely more than-50 DEG C, open microwave heating system and material is carried out concurrent heating, when temperature of charge is higher than preset temperature, being turned down by magnetron voltage or to 0, reduce microwave heating power, temperature of charge will gradually lower；When temperature of charge is higher than preset temperature, being tuned up by magnetron voltage, strengthen microwave power, temperature of charge will be gradually increasing.When carrying out combined drying, first material is carried out deep fat vacuum lyophilization and moves it to microwave dry storehouse to material water ratio about 40%, vacuum breaker storehouse door opening, after it carried out microwave vacuum freeze be dried, middle operating process is similar to.
Being summed up, the equipment of the present embodiment has the advantage that
1) deep fat dry storehouse, water catching bin and microwave dry storehouse are tubular storehouse, deep fat dry storehouse and water catching bin are in front and back's disjunctor configuration, deep fat dry storehouse barrel has a circular hole, the microwave dry storehouse end, side of mounting flange is provided with and shielded stream plate, two warehouses are hinged by flange right angle, use seal with elastometic washer flange, microwave leakage can be prevented, two warehouse vacuums can be kept again consistent.
2) three warehouses are placed on frame, and refrigeration unit, vacuum pump set and heating system of hot oil are placed under frame, and switch board is placed in microwave dry storehouse door front suitable location, rationally distributed.
3) using " torr two " Model Design equipment, i.e. conventional dry storehouse and microwave dry storehouse share a set of refrigeration unit, vacuum pump set, water vessel and control system, therefore compact conformation, cost economy.
4) microwave generator is interspersed along microwave dry storehouse is axially asymmetric, makes microwave play one's part to the full.Using the single phase ac controllable silicon phase shift solid-state voltage regulator being easy to PLC control to change the on-load voltage on each anode of magnetron respectively, and then change anode current reaches to regulate microwave heating power, simple operation, automaticity is high.
In a word, heating system, refrigeration system, vacuum system, water vessel, dry storehouse and TT&C system are organically combined by the equipment of the present embodiment, microwave is combined with conventional two kinds of vacuum lyophilizations of deep fat, can maximize favourable factors and minimize unfavourable ones, in addition to heating system and dry storehouse, remaining four subsystem dual-purpose, thus compact conformation, significantly reduce equipment cost.
