熱(re)風(feng)循環(huan)烘(hong)(hong)(hong)(hong)箱(xiang)(xiang)(xiang)(xiang)一般有(you)加熱(re)管(guan)，有(you)循環(huan)風(feng)機(ji)(ji)(ji)的(de)烘(hong)(hong)(hong)(hong)箱(xiang)(xiang)(xiang)(xiang)都(dou)可稱(cheng)為(wei)熱(re)風(feng)循環(huan)烘(hong)(hong)(hong)(hong)箱(xiang)(xiang)(xiang)(xiang)，因為(wei)不管(guan)烘(hong)(hong)(hong)(hong)箱(xiang)(xiang)(xiang)(xiang)什么結構，風(feng)向水平還(huan)是垂直，歸根到底都(dou)是熱(re)風(feng)在(zai)里面(mian)循環(huan)，所以都(dou)可通稱(cheng)為(wei)熱(re)風(feng)循環(huan)烘(hong)(hong)(hong)(hong)箱(xiang)(xiang)(xiang)(xiang)，如(ru)(ru)電熱(re)鼓(gu)風(feng)烘(hong)(hong)(hong)(hong)箱(xiang)(xiang)(xiang)(xiang)，對(dui)開(kai)門高溫滅(mie)菌(jun)烘(hong)(hong)(hong)(hong)箱(xiang)(xiang)(xiang)(xiang)等。但是一般行業中(zhong)所稱(cheng)熱(re)風(feng)循環(huan)烘(hong)(hong)(hong)(hong)箱(xiang)(xiang)(xiang)(xiang)大(da)多數還(huan)是特指如(ru)(ru)上(shang)圖所示(shi)的(de)烘(hong)(hong)(hong)(hong)箱(xiang)(xiang)(xiang)(xiang)，其它烘(hong)(hong)(hong)(hong)箱(xiang)(xiang)(xiang)(xiang)都(dou)是由上(shang)圖烘(hong)(hong)(hong)(hong)箱(xiang)(xiang)(xiang)(xiang)演變而來，比如(ru)(ru)有(you)了高溫滅(mie)菌(jun)的(de)要求(qiu)，風(feng)機(ji)(ji)(ji)改成風(feng)冷(leng)規(gui)范(fan)化的(de)環(huan)風(feng)機(ji)(ji)(ji)，前后開(kai)門，風(feng)道(dao)也(ye)作(zuo)出了改變，就變成對(dui)開(kai)門高溫滅(mie)菌(jun)烘(hong)(hong)(hong)(hong)箱(xiang)(xiang)(xiang)(xiang)。熱(re)風(feng)循環(huan)分為(wei)五種標準型號(hao)。分別是單門單車(che)，兩門兩車(che)，兩門四車(che)，三門六車(che)，四門八車(che)。
