Raw khoom nthuav dav thiab nthuav cov txheej txheem ntawm qhov cuam tshuam ntawm particle hardness los ntawm kev nthuav dav ntawm cov khoom siv raw thiab kev nthuav dav, tuaj yeem rhuav tshem cov khoom noj khoom haus hauv cov khoom siv raw, tshem tawm cov co toxins hauv cov khoom siv raw, tua cov kab mob, tshem tawm cov khoom tsis zoo, yog li tias cov khoom siv raw hauv cov protein denaturation, hmoov txhuv nplej siab tag nrho pasted, pasted starch ntawm hardness ntawm cov khoom tom qab qhov cuam tshuam yog qhov tseem ceeb. Tam sim no, puffed raw cov ntaub ntawv yog tsuas yog siv nyob rau hauv zus tau tej cov qib high-qib cov khoom noj npua npua thiab cov khoom siv dej tshwj xeeb. Rau cov khoom siv dej tshwj xeeb, cov khoom siv raw los ntawm kev nthuav dav, cov hmoov txhuv nplej siab qib siab ntxiv, qhov nyuaj ntawm cov khoom tsim kuj nce ntxiv, uas yog qhov tsim nyog los txhim kho kev ruaj ntseg ntawm cov khoom hauv dej. Rau kev pub npua noj, cov khoom yuav tsum yog crispy, tsis nyuaj, uas yog qhov zoo rau kev pub npua. Txawm li cas los xij, lub hardness ntawm pelletized granules loj dua vim tias qhov ntau dua ntawm cov hmoov txhuv nplej siab dextrinization, yog li qhov hardness ntawm pelletized granules kuj loj dua, thiab hardness ntawm granules yuav tsum tau txo los ntawm lwm txoj kev.
Raw khoom sib tov, ntxiv dej, roj txau txheej txheem ntawm qhov cuam tshuam ntawm particle hardness ntawm raw cov ntaub ntawv tuaj yeem txhim kho cov uniformity ntawm ntau yam particle loj Cheebtsam, uas yog conducive mus tswj lub hauv paus sib xws ntawm particle hardness, txhim kho cov khoom zoo. lub tov khoom tseem yog ib qho teeb meem uas tab tom tshawb nrhiav. Hauv kev tsim cov khoom noj pellet nyuaj, ntxiv 1 feem pua mus rau 2 feem pua ntawm cov dej hauv cov khoom sib tov yog qhov tsim nyog rau kev txhim kho qhov ruaj khov thiab tawv tawv ntawm pellet pub particles.Txawm li cas los xij, vim qhov nce ntawm noo noo, nws ua rau muaj kev cuam tshuam tsis zoo rau ziab thiab txias. ntawm cov pellets, thiab nws kuj yog qhov tsis zoo rau kev khaws cia ntawm cov khoom.Nyob rau hauv kev tsim cov pellet ntub dej, txog li 20 feem pua mus rau 30 feem pua ntawm cov dej noo tuaj yeem ntxiv rau cov hmoov, thiab nws yooj yim dua ntxiv txog 10 feem pua ntawm cov dej noo hauv cov pellets. cov txheej txheem sib tov dua li hauv cov txheej txheem tempering.Cov pellets tsim los ntawm cov ntaub ntawv muaj cov dej noo tsis tshua muaj zog, ntub thiab muag muag, nrog cov palatability zoo, uas tuaj yeem txhim kho kev ua haujlwm ntawm cov tsiaj nyeg thiab nqaij qaib. Cov pellet ntub dej no tuaj yeem siv rau hauv kev lag luam loj loj. Cov pellets ntub dej feem ntau tsis tuaj yeem khaws cia, feem ntau xav tau cov khoom uas tau noj. Nyob rau hauv cov txheej txheem sib xyaw kom ntxiv cov roj yog tam sim no muaj kev cob qhia pub khoom noj uas feem ntau siv rau hauv cov txheej txheem rog ntxiv. Ntxiv 1 feem pua rau 2 feem pua ntawm cov rog thiab roj kom txo cov tawv nqaij ntawm cov pellets tsis yog qhov tseem ceeb, tab sis ntxiv 3 feem pua rau 4 feem pua ntawm cov rog thiab cov roj tuaj yeem txo qhov nyuaj ntawm cov pellets.
