In large rice milling units, two or even more milling processes are often used in order to achieve higher-quality rice output. The aim of this multiple milling is to achieve a balance between rice quality, yield and grain processing efficiency. The reasons why multiple polishing is used in the large rice processing unit are discussed in detail below.

Uondoaji wa uchafu na maganda: kusaga kwa mchele wa kwanza

Kusudi kuu la kusaga kwa kwanza ni kuondoa maganda na uchafu kutoka kwa mchele. Wakati wa kuvuna na kuhifadhi, uchafu kama vile vipande, mawe, n.k., unaweza kuwa kwenye mchele. Kwa kuongeza, uwepo wa maganda ya mchele pia unaweza kuathiri mchakato wa kusaga unaofuata. Kupitia kusaga kwa mchele wa kwanza, maganda haya na uchafu utatolewa kwa ufanisi, kuweka msingi wa usindikaji unaofuata.

Kusaga kwa mchele wa pili ni zaidi kwa usahihi wa kusaga. Baada ya kusaga kwa kwanza, ingawa maganda na uchafu umekatwa, bado kuna sehemu ambazo hazijakatwa kikamilifu. Kwa kuongeza, kunaweza kuwa na usawa usio sawa kati ya grains za mchele. Kusaga kwa pili kunaweza kusaga grains za mchele kwa usahihi zaidi, kuhakikisha kila grain inapata ukubwa na umbo unaotakiwa, kuboresha ubora na ladha ya mchele.

Kuongeza mavuno ya mchele: kusaga mara nyingi

Kusaga mara nyingi kunaweza kuongeza mavuno ya mchele. Mavuno ya mchele ni asilimia ya mchele kinachoweza kuliwa kinachopatikana kutoka kwa mchele wa awali wakati wa usindikaji. Kwa kusaga mchele mara kadhaa, mchele wa asili unatumika kikamilifu zaidi, kupunguza upotevu na kuongeza mavuno. Hii ina manufaa makubwa ya kiuchumi kwa usindikaji wa mchele wa kiwango kikubwa.

The multiple rice milling process also gives the rice processing plant greater flexibility. Different types of paddy may require different processing methods, and through multiple milling, the processing plant can adjust the number of milling times and parameters to meet the needs of different paddy varieties and produce different types of rice suitable for the market.
