IQF隧道冷冻机在各种水产品和冷冻食品的快速冷冻加工中越来越常用,以最大程度地保持食品的原始营养价值、色泽和风味。IQF代表单个快速冷冻。高速隧道冷冻机用于连续快速冷冻原料。只需将货物放入隧道冷冻机,制冷单元将持续运行,直到货物停止输送。隧道瞬时冷冻机的制冷单元会根据隧道内的温度自动停止,这不仅提高了利用率和生产效率,还节省了因频繁启动而消耗的电力。

隧道瞬时冷冻机的广泛应用

高速隧道冷冻机的输送带与制冷设备的接触距离较短,依靠对流吹风等快速冷却方式。因此,IQF隧道冷冻机非常适合小包装的水产品,如虾、鱼片、鱿鱼、扇贝、海带等,以及冷冻意大利面产品,如饺子、汤包等。

具体而言,以下是常见类别

  • 冷冻意大利面,包括饺子、包子、馒头、烘焙米饭等
  • 冷冻水产品和畜牧产品,包括海虾、鸡爪、猪肉、鱼等
  • 冷冻蔬菜和水果(预处理后),包括冷冻草莓、冷冻青豆等
  • 冷冻菜肴:半成品和成品菜,经过加热后即可食用

高速隧道冷冻机的独特特性

在冷冻过程中,会发生各种物理和化学变化,如体积缩小、干耗增加、蛋白质变性、颜色变化、生物和微生物活性变化等。快速冷冻过程使上述变化达到最大可逆性。通过超低温快速冷冻,在几分钟到十分钟内,食品中心温度达到-18度,满足食品新鲜度的要求。

工业冷冻隧道,根据所用输送带的不同形式,可分为网带式和板带式。用于食品加工的IQF隧道冷冻机通过网带或板带输送机实现。此外,如常用的全铝合金蒸发器沿隧道冷冻机钢板带的运行方向布置,表面不易结霜,增加风量后可实现长时间连续快速冷冻处理。隧道冷冻机的长度从7100mm到26000mm不等,以满足不同客户的需求。

IQF隧道冷冻机如何实现完美的食品保鲜效果?

The blast tunnel freezer is to freeze food in a very short time so that the central temperature of the food reaches -18 ℃. The short time of rapid freezing can avoid the generation of large ice crystals between cells and reduce the precipitation of water inside the cells so that the time for concentrated solutes, food tissues, colloids, and various components to come into contact with each other inside the cell tissues is significantly shortened, and the concentration is reduced to a minimum.

这样,水分子在组织中形成均匀分布的小晶体,不会刺破细胞膜,确保食品微观结构的完整性。解冻后,食品的细胞液流失极少,从而保持其原有的口感、风味和营养价值。

At the same time, the low-temperature environment during the operation of the industrial freezing tunnel is under the activity temperature of microorganisms and enzymes, whose growth and biochemical reactions are effectively inhibited, which also better ensures the freshness of the food and improves the subsequent cold chain circulation rate.

A Flash freezer machine is another kind of quick-freezing equipment, which is often used for small and medium frozen food processing units.
