Existing drying equipment, the most is convection heat transfer drying. Such as hot air drying, hot air and the material to be dried in contact with heat exchange to evaporate moisture. Convection dryer representative of the common types of equipment air suspension dryer, such as fluidized bed dryer, flash dryer, air dryer, spray dryer, ventilated dryer, flow dryer, air rotary dryer, Triomadóir corraitheach, triomadóir sreafa comhthreomhar, triomadóir rothlach agus mar sin ar .
Tá an t -iarratas iarbhír, tá úsáid meaisín aonair ann, tá meascán d'úsáid mheaisín ann, tá samhlacha dífhoirmithe ann freisin agus mar sin ar . tá triomadóir sreafa aeir, triomadóir leaba sreabhach, triomadóir spraeála, etc . aer te mar an t -iompróir teasa, agus iad ag triomú ag an am céanna. codanna .
The most common way to dry powder, granule and flake materials is to apply hot air or gas flow on the surface of the granule. The passing gas stream transfers heat to the material, causing the water to evaporate. The evaporated water vapor goes directly into the air to be taken away, to the drying system commonly used drying media are air, inert gas, direct combustion gas or superheated gaile .
Déanann an modh an t-aer te agus an t-ábhar teagmhála díreach, agus uisce {. a théamh agus á bhaint de agus is é an eochair ná an limistéar teagmhála idir an t-ábhar agus an t-aer te a fheabhsú chun cosc a chur ar shreabhadh an chlaonta aeir te . Tá teocht an ábhair le linn triomaithe luas tairiseach a thriomú beagnach mar an gcéanna le triomaigh a thriomú}}}}}}}}}}}} Is féidir le húsáid an t-aeir ard a úsáid chun an t-ábhar seo a úsáid freisin} seo a úsáid go n-úsáidtear an t-ábhar seo} Is féidir le húsáid seo a bheith in ann an t-ábhar a bheith ann a úsáidtear an t-am Tá an ráta ard, níos lú infheistíochta i dtrealamh, ach tá an éifeachtúlacht theirmeach íseal, is é seo a leanas an staid bhunúsach de chineálacha éagsúla trealaimh triomaithe triomaithe .
(1) Turas níos tirime de chineál bosca
Tá sé ar cheann de na triomadóirí is sine . Déantar an t -ábhar a luchtú leis an bpláta, cuirtear an pláta sa chiseal carranna fráma trí urscaoileadh ciseal isteach sa ghal nó sa leictreachas mar fhoinse teasa, is féidir an t -aer te sa bhosca a scaipeadh agus cuid den urscaoileadh, chun an t -urscaoileadh a úsáid, ach go bhfuil an t -urscaoileadh fós, ach go bhfuil an t -urscaoileadh i gcónaí, ach go n -úsáideann an t -urscaoileadh i gcónaí, ach go bhfuil an t -urscaoileadh i n -aonfhoirmeach, ach go bhfuil an éifeachtúlacht i gcónaí, ach go bhfuil an éifeachtúlacht in ann, go bhfuil an t -uimhreacha i gcónaí ag an am céanna, ach continue to manufacture, because the structure is simple, the operation is not often care no obvious problems. But a lot of material drying to turn over the plate, turn over the powder, heat-sensitive materials are often easy to discoloration, but also does not apply to the drying of materials with solvents. Due to the accumulation of materials, the inner layer of heat transfer, mass transfer is poor, and thus the drying rate is Íseal .
(2) Seomra triomaithe de chineál tolláin
Cuirtear an tráidire ábhartha ar charr speisialta, ar féidir é a dhéanamh go huaineach isteach agus amach as an tollán, chun an t -aschur a mhéadú agus chun an éifeachtúlacht theirmeach a fheabhsú . tá struchtúir eile cosúil leis an triomadóir bosca .
(3) Triomadóir crios mogalra
Can be used for drying corn, grains, vegetables and so on. This machine is equipped with stainless steel wire mesh transmission belt, the material moves with the belt, can be heated in sections. The device to each section 1.8 ~ 2m long as a unit, the longest can be connected to 40m, the hourly capacity can be as high as 4T . Ráta tairiseach na céime triomaithe de theocht an aeir te suas le 130 céim, taise coibhneasta sceite suas le 85%.
(4) Triomadóir tuirbín ilchisealach
Its structure is a vertical garden cylinder, equipped with a number of layers of turntable, the material can be added from the top, layer by layer down to the bottom of the release. Hot air from the bottom of the introduction, set up in the center of the cylinder by a number of blower turbine impeller segmentation cycle air, and the corresponding height of the inner wall of the heater to supplement the heat of the air to improve thermal Ráta éifeachtúlachta agus triomaithe . Mar sin féin, níl an trealamh éasca a ghlanadh, chun go leor cineálacha a tháirgeadh agus tá sé níos deacra an ceanglas maidir le hábhair ghlana a tháirgeadh .
