Sokeritehdas Puunenessa, Hawaijilla.


Sokeritehdas on tehdas, jossa valmistetaan sokeria. Sokeritehtaissa valmistettava sokeri valmistetaan erikseen pelloilla kasvatettavista sokerijuurikkaista tai lämpimissä maissa kohdattavasta sokeriruosta.[1] Tehtaat joissa valmistetaan sokeria juurikkaista, ovat käytössä vain syksyisin, jolloin juurikkaat ovat kypsyneet valmiiksi. Maailman ensimmäinen sokerijalostamo perustettiin New Yorkiin vuoden 1690 paikkeilla.[2]


Suomessa on tällä hetkellä jäljellä yksi sokeritehdas, joka on Säkylässä. Säkylän sokeritehdas on ollut sitkeästä toiminnassa pysymisestään huolimatta useaan kertaan vaakalaudalla toiminnan jatkumisen osalta.[3]



Sokerin valmistaminen |


Kun sokerijuurikaskuorma on saapunut tehtaalle, se punnitaan. Sen jälkeen jokaisesta kuormasta otetaan koneellisesti 25–35 kg:n näyte, joka tutkitaan koepesulassa. Tällä tavalla saadaan selville juurikkaiden puhtaus, sokeripitoisuus ja saanto, joiden avulla tietokone tekee viljelijöille suoritettavat tilityslaskelmat.[4] Tämän jälkeen on vuorossa pesu, jossa juurikkaat esipestään voimakkaalla vesisuihkulla ja josta ne joutuvat tehtaalle käsiteltäväksi. Sitten kivenerottimet poistavat juurikasvirrasta kiviä, hiekkaa ja savea.[4] Sokerijuurikkaiden leikkauksen jälkeen ne erotetaan leikkeestä yli 20 metriä korkeassa uuttotornissa, jossa leike kulkee alhaalta ylöspäin ja vesi päinvastoin. Leike viipyy 70-asteisessa uuttolaitteessa 1,5 tuntia. Muodostunut sokerimehu poistuu leikemaissista. Mehu sisältää noin 14–15 % sokeria.[4]


Tämän jälkeen sokeri melassataan, eli kuivataan. Kuivauksen jälkeen tuote pakataan joko sellaisenaan paperisäkkeihin tai puristetaan rakeiksi, joiden toimitus tapahtuu siiloista irrallisena.[4]
