Abstract
一种鲽鱼片速冻工艺，包括以下步骤：(1)、摆盘，对加工成型的鲽鱼片进行装盘、覆盖塑料片；(2)、预冷，将装盘的鲽鱼片放入冷冻室内预冷，预冷温度为‑2℃‑‑10℃，预冷时间为15‑20分钟；(3)；冷冻，取下整形塑料片，将装盘的鲽鱼片放入单冻机内进行冷冻，冷冻温度为‑20℃以下。本发明的鲽鱼片速冻工艺，通过对加工成型的鲽鱼品进行预冷，并在鲽鱼片速冻前去掉整形塑料片，有效地提高了鲽鱼片的速冻时间。
Description
技术领域
本发明涉及水产品加工技术领域。
背景技术
鲽鱼，又称比目鱼，比目鱼富含蛋白质、维生素A、维生素D、钙、磷、钾等营养成分，尤其维生素B6的含量颇丰，而脂肪含量较少。另外，比目鱼还富含大脑的主要组成成分DHA，经常食用可增强智力；肉质细嫩而洁白，味鲜美而肥腴，补虚益气，因此受到广大群众的喜爱。
鲽鱼产品加工工艺包括原料解冻、去鳞、开片去刺、检查、清洗、浸泡、粘合摆盘、单体速冻、包装、金属探测及装箱入库等过程。产品在速冻过程中，主要是用直接接触式单体速冻机，鱼片在送去单冻机前，上面覆盖一层塑料片，虽可防风吹走型、不平整，但也影响换热效率和冷冻速度。
发明内容
为了解决现有鲽鱼产品速冻工艺存在的上述问题，本发明提供了一种鲽鱼片速冻工艺。
本发明为实现上述目的所采用的技术方案是：一种鲽鱼片速冻工艺，包括以下步骤：
(1)、摆盘，对加工成型的鲽鱼片进行装盘、覆盖塑料片；
(2)、预冷，将装盘的鲽鱼片放入冷冻室内预冷，预冷温度为-2℃--10℃，预冷时间为15-20分钟；
(3)；冷冻，取下整形塑料片，将装盘的鲽鱼片放入单冻机内进行冷冻，冷冻温度为-20℃以下。
所述步骤(2)中，优选的预冷温度为-4℃，优选的预冷时间为15分钟。
所述步骤(3)中，冷冻温度为-35℃以下。
本发明的鲽鱼片速冻工艺，通过对加工成型的鲽鱼品进行预冷，并在鲽鱼片速冻前去掉整形塑料片，有效地提高了鲽鱼片的速冻时间。
具体实施方式
本发明的鲽鱼片速冻工艺，包括以下步骤：
(1)、摆盘，对加工成型的鲽鱼片进行装盘、覆盖塑料片；
(2)、预冷，将装盘的鲽鱼片放入冷冻室内预冷，预冷温度为-4℃，预冷时间为15分钟；
(3)；冷冻，取下整形塑料片，将装盘的鲽鱼片放入单冻机内进行冷冻，冷冻温度为-35℃以下。
对于加工成型的鲽鱼片进行预冷，预冷后进入速冻机，延缓单冻机体内的蒸发器表面的结霜速度，从而提高蒸发器的预冷效果，经过预冷的鲽鱼片，在进入单冻机体前去掉整形塑料片，提高热传到效果，冷冻速冻提高两倍以上。降低了产品速冻时间，分保持鲽鱼片完好的形状，提高了生产效率。
本发明是通过实施例进行描述的，本领域技术人员知悉，在不脱离本发明的精神和范围的情况下，可以对这些特征和实施例进行各种改变或等效替换。另外，在本发明的教导下，可以对这些特征和实施例进行修改以适应具体的情况及材料而不会脱离本发明的精神和范围。因此，本发明不受此处所公开的具体实施例的限制，所有落入本申请的权利要求范围内的实施例都属于本发明的保护范围。
