How to ensure the drying uniformity and stability of industrial dryers?

Reasonable design of hot air circulation system
Hot air circulation is the core link of the drying process of industrial dryers . Is féidir le dearadh réasúnach dhuchtanna aeir agus córais dáilte aeir te cabhrú le dáileadh aonfhoirmeach an aeir te a bhaint amach agus spotaí dall róthéamh nó teochta áitiúil a sheachaint. Is féidir le húsáid an tsoláthair aeir nó an chórais aeir ar ais, in éineacht le socrú cuí lucht leanúna, cúrsaíocht mhaith aeir a chruthú agus éifeachtúlacht aistrithe an aeir te a fheabhsú. Ina theannta sin, tá rialú réasúnach ar luas na gaoithe ina gcabhair ar aistriú teasa aonfhoirmeach agus laghdaítear an difríocht teochta ar dhromchla na n -ábhar.

Choose the right type and structure of dryer
Industrial dryers of different types and structures have different drying uniformity. Tá a gcuid tréithe féin ag druma, crios, rothlach agus triomadóirí eile, agus ba cheart an roghnú a chomhcheangal leis na hairíonna ábhartha agus na riachtanais táirgthe. Ba chóir go ndéanfadh an dearadh struchtúrach machnamh ar an am cónaithe agus an modh sreafa san ábhar sa trealamh chun a chinntiú go ndéantar an t -ábhar a théamh go cothrom sa limistéar triomaithe ar fad. Equipment with layered or multi-layer structures needs to focus on the balance of temperature and humidity in each layer.

Accurate control of drying parameters
Process parameters such as temperature, humidity, wind speed and drying time have an important influence on drying uniformity. D'fhéadfadh teocht ró-ard a bheith ina chúis le dromchla an ábhair a bheith ró-thriomaithe nó fiú meathlaithe, agus d'fhéadfadh sé go mbeadh triomú neamhleor mar thoradh ar an teocht ró-íseal. By real-time monitoring and adjustment of temperature and humidity parameters, fluctuations in the drying process can be avoided. Ní mór luas na gaoithe a shocrú go réasúnach de réir thréithe an ábhair, chun aistriú teasa a chinntiú agus chun an t -ábhar a shéideadh nó a dhamáistiú mar gheall ar luas iomarcach na gaoithe.

Use automated monitoring and adjustment system
Modern industrial dryers are equipped with automated control systems, which collect temperature, humidity and wind speed data in real time through sensors, and realize dynamic adjustment in combination with computer or PLC systems. Is féidir leis an gcóras rialaithe uathoibríoch freagairt do thimpeallacht táirgthe agus athruithe ábhartha ar bhealach tráthúil, trealamh téimh, luas lucht leanúna agus oscailt calafoirt díhiodráitithe a choigeartú, agus cobhsaíocht an phróisis triomaithe a chinntiú. Automatic alarm and fault diagnosis functions help prevent abnormal conditions and reduce uneven drying.

Evenly distribute materials and load them reasonably
The loading method and even distribution of materials are crucial to the uniformity of drying. Avoid material accumulation, blockage or over-crowding to ensure that the hot air can fully contact every part of the material. In belt and drum dryers, the material should be kept flowing continuously and evenly to avoid dead corners and short-flow. For granular or loose materials, stirring and turning devices can be used to assist in even drying.

Regular maintenance and equipment calibration
The maintenance of equipment affects the operating status and drying effect. Ba chóir na lanna lucht leanúna, na dhuchtanna aeir agus na heilimintí téimh a ghlanadh go rialta chun carnadh agus bacainn deannaigh a chosc, agus an t -aerchúrsaíocht a choinneáil gan bhac. The temperature sensor and control system need to be calibrated regularly to ensure the accuracy of the measurement data. The body structure with good sealing performance can effectively reduce the leakage of heat and hot air. The sealing parts should be checked during maintenance.

Reasonable arrangement of production process
In production management, reasonable arrangement of drying batches and processes can also help to dry evenly. Avoid frequent changes in drying parameters and keep the equipment running in a stable state. According to the type of material and moisture content, reasonably adjust the drying time to prevent excessive or insufficient drying. Process tests can be carried out on different batches of materials to determine the optimal parameters.
