Lub luag haujlwm ntawm cov tshuaj yej nplooj dov yog dab tsi: dov, ib qho ntawm cov tshuaj yej ua cov txheej txheem, feem ntau cov txheej txheem tshuaj yej muaj cov txheej txheem no, lub npe hu ua dov tuaj yeem nkag siab tias yog ob txoj haujlwm, ib qho yog tshuaj yej kneading, tshuaj yej kneading txawm tias cov tshuaj yej nplooj yog tsim rau hauv ib daim hlab, ib tug yog twisting, twisting tau Cov tshuaj yej hlwb tawg, thiab cov tshuaj yej kua txiv yog squeezed tawm, thiaj li hais tias cov tshuaj yej kua txiv yog txuas mus rau saum npoo ntawm cov tshuaj yej bar, uas tsub kom lub viscosity thiab yog conducive rau tsim. ntawm cov duab ntawm cov tshuaj yej nplooj.

Ntxiv nrog rau shaping, kev ua haujlwm ntawm dov yog tsuas yog ua rau cell breakage thiab overflow ntawm cov kua txiv hmab txiv ntoo.Cov kua txiv hmab txiv ntoo overflowed adheres rau saum npoo ntawm nplooj tsim.Tom qab ziab, xim thiab saj tuaj yeem brewed los ntawm brewing.Yog li ntawd, kneading yog txheej txheem tsim nyog rau kev ua txhua yam tshuaj yej (tshwj tsis yog tshuaj yej dawb).

Kev ua haujlwm ntawmtshuaj yej dovyog ua kom cov tshuaj yej nplooj mus rau hauv ib daim hlab, thiab qhov thib ob yog ua kom cov hlwb nyob rau hauv cov tshuaj yej nplooj, thiab cov tshuaj yej kua txiv overflows thiab adheres rau saum npoo ntawm cov tshuaj yej nplooj, uas yog pab tau kom lub concentration ntawm cov tshuaj yej kua zaub, kuj yog vim li cas cov tshuaj yej tawm cov kua zaub sai sai.Qhov hnyav dua cov tshuaj yej nplooj yog, qhov tsawg resistant cov tshuaj yej nplooj yog foaming.

Muaj ob txoj hauv kev kneading, phau ntawv kneading thiab mechanical kneading.Tam sim no, tsuas yog qee qhov kev ua tshuaj yej nto moo, uas tseem khaws cia me me ntawm phau ntawv dov, feem ntau ntawm lawv tau ua tiav cov haujlwm ua haujlwm.
