Abstract
黑木耳压缩成型方法。将黑木耳干品经过挑选处理、调湿、升温、称重、装模、成型、脱模、干燥、包装等工序,机械压缩成具有一定形状和一定重量的黑木耳块。黑木耳块体积仅为原干品体积的七分之一。解决了黑木耳干品体积大,储存、运输不便和储存、运输时费用高及破碎等问题,提高了黑木耳产品的质量,泡发后可100%恢复原状,不需清洗即可直接烹调菜肴。
Description
本发明涉及一种农副产品加工方法。
目前,食用黑木耳,不论是天然生长的还是人工栽培的,都采用自然干燥法或人工加热干燥法将其加工成一朵一朵的干品。这种黑木耳干品体积大,储存、运输很不方便,而且费用高。在储存、运输过程中还容易破碎或霉变、虫蛀。另外,这种黑木耳干品中往往都混有木屑、树叶、杂草等杂质,食用不便。经检索国际专利文献,未发现黑木耳压缩加工成型的方法。
本发明的目的就是提供一种黑木耳加工成型的方法,改变黑木耳干品的几何形状,缩小体积,方便储存和运输,提高产品质量。
本发明的技术方案是:将黑木耳干品经过挑选处理、调湿、升温、称重、装模、成型、脱模、干燥、包装等工序,机械压缩成具有一定形状和一定重量的黑木耳块。
1、挑选:剔除黑木耳中的木屑、树叶、杂草等各种杂质及次耳。
2、调湿:在经过挑选的黑木耳干品上均匀地喷洒3~10%的清水。
3、升温:经干燥或调湿处理后的黑木耳在20~50℃条件下,
放置1~6小时。
4、称重:将经过升温处理的黑木耳,按每块净重量的要求进行称重。
5、装模、成型:将经过升温处理的黑木耳称重后放入钢模中,在3.21~4.15MPa压力下加压2~5分钟。
6、干燥:将压缩成型的黑木耳块,在-5~15℃条件下干燥1~2天。干燥后的成品含水量不大于14%。
7、包装:黑木耳块可用玻璃纸或塑料薄膜等包装材料进行包装、装璜。
本发明的工艺流程简图:
本发明的优点:
1、采用本发明方法制成的黑木耳块体积仅为原干品体积的七分之一,便于储存和运输,同时可节省仓储、运输费用,减少损失。
2、在压缩成型过程中,不加入任何添加剂即可使其凝聚在一起,并坚固不易碎。
3、在加工过程中不损失黑木耳的营养成分。食用时,在温水中浸泡15分钟即可100%泡发,恢复黑木耳的原状。
实施例:
取经过挑选处理的黑木耳干品300克,均匀地喷洒清水15克,在30℃的条件下升温5小时,升温结束后,按每块30克的重量称重后装入钢模中,在3.30MPa压力下加压5分钟。从钢模中取出黑木耳块后立即置入0℃的冰箱中干燥24小时。用玻璃纸包装后即可获得10块黑木耳块。每块净重30克,长7cm,宽5cm,厚0.8cm。每10块可以包装成一盒。

1、一种把黑木耳机械压缩成型的方法,其特征是:将黑木耳干品经过干燥或调湿、升温、装模、成型、干燥等工序,压缩成具有一定形状和一定重量的黑木耳块,
a、调湿:在经过挑选处理的黑木耳干品上均匀的喷洒3~10%的清水,(若原干品过潮时,需进行干燥处理),
b、升温:经干燥或调湿处理后的黑木耳在20~50℃条件下,放置1~6小时,
c、装模、成型:将经过升温处理的黑木耳经称重后装入钢模中进行压缩,在3.21~4.15MPa压力下加压2~5分钟,
