Kelp drying
Release time:
福建霞浦资源丰富,海带种植面积很大,但如何将天然鲜海带变成干海带,几乎是靠天气,而且晒出的干海带的质量也很不稳定。这几年,随着高温热泵成功的在许多行业的烘干干燥上的应用,霞浦某海带加工厂联系到我们,希望可以使用我们的空气能高温热泵,为他们解决这个海带的烘干的问题。在我们与海带厂的协助下,高温热泵设计的海带烘干房生产出的海带平展,不粘连,烘干快,颜色好。晾晒的海带,无论从质量、色泽比自然晾晒烘干出的海带胜出一筹。

海带加工工艺步骤:
1、鲜原料入库:原料来自备案养殖基地;
2、烫煮:将海带放入烫煮流水线90℃~99渍高温烫煮;
3、盐渍:烫煮冷却后钣盐(盐用量为鲜海带的40%)
4、入库:冷库要求0℃~18℃
5、切断:从冷库中将原料取出,人工去掉表面盐分加以切断
6、清洗脱盐:将预处理后的海带清洗3遍,保证不存在任何异物,盐分控制在0.2%含量以下。
7、摆盘:将清洗好的海带丝摆入网盘

8、烘干:
第一阶段,升温阶段:将装好物料的托盘,平整的放入烘箱,不能重叠,避免托盘放置不好造成不必要的漏风。关闭箱门,箱内温度加热至50°,加热1.5-3小时,看箱内有湿气时,开始排潮,大约排潮2分钟左右,排潮后箱内温度会有所下降,继续供热。
第二阶段。恒速干燥排潮阶段:应分高湿低温、中湿中温两个阶段。高湿低温段,温度小于60度,范围55度~60度,避免高温高湿造成物料颜色的变化,观察物料表面水汽变化,随时排潮,这段时间应在3~3.5小时。中湿中温段,温度小于60度,范围50度~60度,此段排潮可以适当打开进风阀门,适当关闭回风阀门,根据潮气多少合理调整。
第三阶段,降速定型阶段:也称为低湿高温段,此段温度70度~80度,前期不宜超过70度,后期不宜超过80度。
