Abstract
The utility model relates to a hot-blast and cold-blast drying test device, which is improved on the basis of the original GZ-1 model hot-blast drying test device, comprising a ventilating pipeline, a blower fan, a heating wire, a hole plate manometer, etc. The utility model is characterized in that the ventilating pipeline is connected in series with a heat pump dryer. The drying test device after the improvement, the original hot-blast drying test characteristic can be kept, simultaneously, the cold-blast drying or the hot-blast drying can be carried out, and the combined drying of the hot blast and the cold blast can be carried out. The utility model is suitable for the teaching experiment and the scientific research experiment, the test data are obtained by the experiment, by the analysis and the calculation, the design of the industrial equipment and the determination of the process parameter of the drying machining are guided.
Description
The utility model is the experimental provision that food industry is used to test the material dry run, especially for the experimental provision of test fruit vegetable materials hot blast and cold air drying process.
Drying experimental device is a kind of experimental provision for production designs, teaching, scientific research provide reference data.At present for fruit and vegetable dryness provides the experimental provision of experimental data GZ-1 type heated-air drying experimental provision is arranged, this device is made up of ventilation shaft, blower fan, heating wire etc.Establish dry materials chamber and heating wire in the ventilation shaft, the material folder is arranged in the hothouse, weight of material with suspension type balance monitoring dry run changes, heating wire energising back heating, by blower fan hot blast is circulated in pipeline material is carried out drying, this experimental provision can only provide data for the heated-air drying material, but it is not good enough that the heated-air drying method exists product quality, shortcomings such as it is big to consume energy, in order to solve the deficiency of heated-air drying technology, the drying means that cold air drying or hot blast combine with cold wind has appearred at present, so original simple heated-air drying experimental provision incompatibility scientific research, education experiment and production designing requirement.
The purpose of this utility model: in order to improve the quality of fruit and vegetable dryness product, the drying means that cold air drying or hot blast combine with cold wind appears on the fruit and vegetable dryness method at present, the utility model makes these drying means have reliable experimental to help the design and processes Parameter Optimization of the equipment of industrial product on industrial production, make production decision more in conjunction with actual, product quality also is improved.The utility model can promote the raising of teaching and scientific research means as teaching equipment and research equipment simultaneously.
The utility model is on the basis of original GZ-1 heated-air drying experimental provision, the heat pump drying device of on the airflow reflux road, having connected, air-flow is circuitous in ventilation shaft, configurable number display type thermometer in hothouse, measure material temperature situation of change in the hothouse, and, be used for monitoring the variation of dry run weight of material with electronic scale and the original suspension type balance of pallet replacement.
Now the utility model is described in further detail in conjunction with the accompanying drawings:
Fig. 1 is the utility model structural representation.
The drying experiment chamber device is made up of ventilation shaft 1, heating wire 2, orifice differential pressure meter 3, hothouse 4, blower fan 5 etc., hothouse 4 is located in the ventilation shaft, establish the pallet 6 of carrying material in the hothouse, the material of weighing for convenience, it under the material tray bottom support 7 of I shape, the I shape cradling piece passes air duct wall fixedlys connected with support plate, bearing support is placed on the electronic scale 8, establish heater strip 2 in the ventilation shaft, heater strip 2 is connected with power supply, blower fan 5 is housed on the ventilation shaft, and the two ends of ventilation shaft connect heat pump drier 9 respectively, form the system of a sealing.
In order to regulate the wind speed in the pipeline, orifice differential pressure meter 3 and blast regulator 10 are housed in ventilation shaft.
In order to measure material temperature in the pallet, disposed material temperature sensing device 11 in the hothouse, the material temperature sensing device is made up of thermocouple thermometer probe and digital display thermometric instrument, and the thermocouple thermometer probe inserts in the material, and material temperature changes and can be shown by the digital display thermometric instrument.
This device can not only carry out independent hot blast or cold air drying, and can carry out hot blast and combine drying with cold wind.
It is work like this that the utility model carries out when hot blast combines drying experiment with cold wind: material to be measured is pressed 5kg/m
2Standard is laid on the material pallet, pallet is positioned over the bearing support top that links to each other with electronic scale in the hothouse, temperature probe is penetrated hothouse from aperture to be inserted the material and is fixed, open the heater strip power supply, start blower fan, the heat that heater strip produces makes air heat by blower fan, hot-air carries out convective drying to material in the pipeline, set baking temperature, regulate hot blast temperature in the pipeline automatically, regulate wind speed by blast regulator by temperature controller.When material dehydration during to the binding site moisture content (so-called binding site moisture content is exactly the moisture content by heated-air drying material when cold air drying is changed), close the heater strip power supply, stop heating, start heat pump drier and carry out cold air drying, continue to be dried to material and reach the terminal point moisture content, be dry the end.
In process of the test, put down in writing various data, as: material moisture binding site, cold wind temperature, cold wind wind speed and drying time when the best hot blast temperature of dry materials, hot blast wind speed, the exchange of cold and hot wind, these data can instruct the design of commercial plant and determining of dry working process parameter by analyzing.
The also convenient teaching of this device, the student is by the use of this device, temperature, humidity, rate of drying, material moisture, the change of wind velocity process that can understand heated-air drying and cold air drying in depth reach the influence to the dried material quality, help improving the quality of teaching and students'ability for practice.
