Huka parakore: ara o whiwhi

Para te huka, i roto i te rerekē ki te kuware huka, he tohu nui o te purenga. Te hokohoko supply kaihanga huka i roto i ngā puka: paura, onepu pēpēhia ranei. Hangarau, i whiwhi nei i te huka para, ohie, whakamahia te rite te pīti rauemi raw rauemi kakaho ranei. hua oti o rua te rauemi tīmata o ngā momo ki te reka o tata nga utu taua, engari rerekē. Production o te huka parakore ko atu te utu i te kakaho rauemi raw me e roa.

Ko te ngako o te tukanga o te whiwhi i te hua e purea ko ki te faaineine i te otinga kukū i reira i whakawhitia ki te āhua tirikara mo anō adsorption tino me te filtration. I muri whakanohoia te puranga hua kei roto i te pūrere korehau, kawea ai te te āhua tonu ki te tōhau. Ki kī reira i te tae hukarere-ma, kua tukinotia reira ki te whakatārewatanga o te ultramarine (ū maa).

I roto i te taahiraa i muri mai, ka taea te hua te huka parakore i roto i ara e rua, i runga i te āhua o te hua whakamutunga rānei - whakarewa extruded ranei. Ko atu te utu, me te uaua te kōwhiringa tuatahi. A, no te para reira huka whiwhi e ringihia papatipu (massecuite) ki ngā puka motuhake, te wahi āta reira paari. Hei tango kua ringihia ki runga ki runga o te otinga o te huka para te tirikara, tenei tukanga toru ranei wha nga wa toutou te. Ka rite ki te hua, nekehia tukatuka o te hua oti te i te pakete, a wehea ki poraka rahi e hiahiatia ana. Ko reira nui māmā me te iti ki te whiwhi huka whakarewa parakore ara, ka puta te WHITENING tirikara i roto i te centrifuge motuhake. kōpeke te rauemi hua te pokanga, ka maroke, a ka wehe i te papatipu mārō ki parallelepipeds.

Tikanga, te aromatawai kounga o te hua hua tikanga organoleptic, i te whakatau i te reka, kakara, tae, te mārama o te otinga. kia Tae o matū parakore ma ki kahore he stains me ma, pea he kauruku kikorangi. Ko te reka reka, kahore atu rongo, te taua pā ki te haunga. E kore e whai i te otinga poke hohenga ka kia mārama ranei paku opalescent. I roto i te āhuatanga physicochemical o te nui tino e:

- hautau papatipu o sucrose, makuku, whakaiti matū;

- ihirangi ferroprimesey;

- tae;

- Pourewa.

Hoki o te faufaa e rerekē ngā āhuatanga microbiological: rewena, tukumate, pakete, MAFAM, BGKP3. paihana Aroturuki (Fostoksin, hexachloran), me matū paitini (te ateneke, cadmium, mata, mēkuri, parahi, konutea). Tākai hua i roto i te puka o te onepu me te paura i roto i pākete, me te puranga huka - i roto i kātene takitahi peke (2 he wahi o te pukapuka toi me te Uwhi) ranei.

kawea Transportation me te rokiroki o te huka parakore te atu i roto i ngā ranei i roto i waka kati. Cars, mau, e kore e whai ipu āputa me te kia maroke, ko te tuanui kore e tīpoka makuku, tatau me pao - piri katia. Me pupuri i te hua i te haumākū o kore neke atu i te 70%, me te pāmahana e kore ki runga ake i te 40 ° C, āta wehea i te tahi atu matū me ngā rauemi.
