Froid positif ou n\u00e9gatif\u00a0?<\/h2>\n

D\u2019abord, les deux cat\u00e9gories de chambre froide professionnelle diff\u00e8rent selon leur type de froid<\/strong>.<\/p>\n

Froid positif<\/h3>\n

Avec une temp\u00e9rature de conservation au-dessus de 0 \u00b0C<\/strong>, les chambres froides positives sont g\u00e9n\u00e9ralement situ\u00e9es \u00e0 3 \u00b0C, selon les aliments stock\u00e9s. En effet, la chambre froide positive<\/a> consiste \u00e0 conserver au frais<\/strong> les produits alimentaires.<\/p>\n

\"chambre<\/a><\/p>\n

Froid n\u00e9gatif<\/h3>\n

Pour une temp\u00e9rature de stockage en dessous de 0 \u00b0C, les chambres froides n\u00e9gatives<\/a> peuvent \u00e9galement \u00eatre restitu\u00e9es \u00e0 –18 \u00b0C<\/strong> selon les produits \u00e0 conserver ou les objets \u00e0 traiter.\u00a0 Ce type de chambre froide<\/a> est con\u00e7u pour la cong\u00e9lation<\/strong> des denr\u00e9es.<\/p>\n

Quelle chambre froide conserve les produits le plus longtemps ?<\/h2>\n

La chambre froide positive n\u2019assure pas une longue dur\u00e9e de conservation des aliments. <\/strong><\/p>\n

En revanche, la cong\u00e9lation des aliments dans une chambre froide n\u00e9gative<\/a> permet de les conserver bien plus longtemps.<\/strong><\/p>\n

Quels produits peut-on stocker dans une chambre froide ?<\/h2>\n

Les produits alimentaires tels que la viande et le poisson doivent \u00eatre congel\u00e9s<\/strong>. Une chambre froide n\u00e9gative permet d\u2019obtenir une temp\u00e9rature qui \u00e9vite la multiplication de bact\u00e9ries sur ces denr\u00e9es. En cas de rupture de la cha\u00eene du froid, ces organismes peuvent se d\u00e9velopper dans les aliments et les rendre impropre \u00e0 la consommation<\/strong>. La chambre froide n\u00e9gative est con\u00e7ue pour le stockage de longue dur\u00e9e<\/strong> tout en pr\u00e9servant la qualit\u00e9 des produits : les denr\u00e9es alimentaires<\/strong>, les m\u00e9dicaments<\/strong>, etc.<\/p>\n

\"chambre<\/a><\/p>\n

Au contraire de la chambre froide n\u00e9gative, la chambre froide positive<\/strong> professionnelle<\/strong> n\u2019offre pas une longue dur\u00e9e de pr\u00e9servation des aliments. La particularit\u00e9 de ce syst\u00e8me de refroidissement est de maintenir la temp\u00e9rature au-dessus de 0 \u00b0C<\/strong>. De ce fait, ce mode de refroidissement exclut le stockage de produits tels que les viandes et poissons pendant une longue p\u00e9riode. <\/strong>Il permet cependant de conserver les produits frais tels que les l\u00e9gumes et fruits, les produits laitiers et les charcuteries.<\/p>\n

Quelle est temp\u00e9rature d\u2019une chambre froide ?<\/h2>\n

G\u00e9n\u00e9ralement, la chambre froide n\u00e9gative<\/strong> affiche une temp\u00e9rature de \u2013 18 \u00b0C<\/strong>, mais elle peut atteindre -63 \u00b0C.<\/p>\n

Les chambres froides positives<\/strong> sont surtout le choix des professionnels de la restauration. Leur plage de temp\u00e9rature s\u2019\u00e9tale de 0 \u00b0C \u00e0 15 \u00b0C.<\/strong><\/p>\n

Chambre froide positive VS chambre froide n\u00e9gative<\/h2>\n
