L'oignon est une herbe vivace de la famille des Liliac\u00e9es et Allium<\/a>. La p\u00e9riode de r\u00e9colte des oignons s'\u00e9tend g\u00e9n\u00e9ralement de la fin mai aux dix premiers jours de juin. Dans notre vie quotidienne, les oignons frais sont g\u00e9n\u00e9ralement utilis\u00e9s comme l\u00e9gumes, tandis que les oignons s\u00e9ch\u00e9s sont g\u00e9n\u00e9ralement utilis\u00e9s dans l'industrie alimentaire et chimique. Voulez-vous conna\u00eetre le processus de s\u00e9chage des oignons ? Aujourd'hui, nous vous donnerons une introduction d\u00e9taill\u00e9e.<\/p>

Processus de s\u00e9chage des oignons<\/h2>

Dans le processus de s\u00e9chage de l'oignon, il est n\u00e9cessaire de pr\u00eater attention \u00e0 la temp\u00e9rature, \u00e0 l'humidit\u00e9 et au temps de s\u00e9chage.<\/p>

  1. Temp\u00e9rature : La temp\u00e9rature de s\u00e9chage des oignons ne doit pas d\u00e9passer 50 \u2103, et le taux de d\u00e9shumidification doit atteindre plus de 20 % lors du s\u00e9chage. Le s\u00e9chage peut se faire en plusieurs \u00e9tapes. La temp\u00e9rature initiale de s\u00e9chage est fix\u00e9e \u00e0 50-40 \u2103, la deuxi\u00e8me \u00e9tape est fix\u00e9e \u00e0 40-30 \u2103, et la troisi\u00e8me \u00e9tape sera r\u00e9duite \u00e0 environ 35 \u2103.<\/li>
  2. Humidit\u00e9 : Pour les l\u00e9gumes \u00e0 forte teneur en eau, il faut contr\u00f4ler l'\u00e9vacuation de l'humidit\u00e9. Car cela fait \u00e9galement partie des facteurs importants qui d\u00e9terminent la qualit\u00e9 du s\u00e9chage.<\/li>
  3. Temps de s\u00e9chage : Le cycle de s\u00e9chage des oignons dure g\u00e9n\u00e9ralement environ 15 heures. Un s\u00e9chage rapide endommagera la qualit\u00e9 du s\u00e9chage.<\/li> <\/ol>

    Comment s\u00e9cher les oignons commercialement ?<\/h2>

    La teneur en eau des oignons est relativement \u00e9lev\u00e9e. La m\u00e9thode traditionnelle de s\u00e9chage des oignons prend beaucoup de temps et favorise la prolif\u00e9ration de bact\u00e9ries. Avec le d\u00e9veloppement de la technologie alimentaire, la plupart des usines de transformation alimentaire utilisent s\u00e9chageurs d'oignons<\/a> pour s\u00e9cher les oignons. Dans le processus de s\u00e9chage des oignons, la machine \u00e0 s\u00e9cher les oignons adopte g\u00e9n\u00e9ralement la m\u00e9thode d'air chaud \u00e0 basse temp\u00e9rature et de s\u00e9chage \u00e0 temp\u00e9rature constante. Car une temp\u00e9rature \u00e9lev\u00e9e d\u00e9truit la valeur nutritionnelle des l\u00e9gumes et leur fait perdre des nutriments.<\/p>

    La machine \u00e0 s\u00e9cher les oignons utilise la technologie de circulation d'air chaud, qui est \u00e9galement la meilleure m\u00e9thode pour s\u00e9cher les oignons. Si vous avez besoin d'un s\u00e9choir \u00e0 oignons, n'h\u00e9sitez pas \u00e0 nous contacter. De plus, vous pouvez \u00e9galement utiliser cette machine pour s\u00e9cher des l\u00e9gumes, des fruits et des m\u00e9dicaments traditionnels chinois tels que piment<\/a>.<\/p>","protected":false},"excerpt":{"rendered":"
