快速回答

专业采购指南:对比速冻间、隧道式、螺旋式及IQF速冻机,按产品和处理量确定产能,评估制冷剂、能耗与供应商询价方案。 速冻设备采用温度更低、速度更高的气流,快速冻结温热产品,保护产品品质。普通冷冻储藏设备主要用于保持已冻结产品的低温状态,用于冻结新入库产品时速度过慢。

要点

  • ▸速冻设备与普通冷冻设备有什么区别? 速冻设备采用温度更低、速度更高的气流,快速冻结温热产品,保护产品品质。普通冷冻储藏设备主要用于保持已冻结产品的低温状态,用于冻结新入库产品时速度过慢。
  • ▸速冻需要多长时间? 取决于产品厚度、包装、进料温度和空气温度。较薄的未包装产品在IQF或螺旋式速冻机中可在几分钟内冻结;速冻间内的大箱产品则可能需要数小时。
  • ▸速冻设备通常在什么温度下运行? 常见空气温度约为−35至−40 °C,产品中心温度达到−18 °C或更低后再转入冷库储藏。
  • ▸应该选择螺旋式速冻机还是速冻间? 螺旋式速冻机适合同类产品的连续大批量生产线;速冻间适合多品类和批次生产。许多工厂会同时使用这两类设备。

冻结速度决定产品品质。食品缓慢冻结时,会形成较大的冰晶,破坏细胞壁,导致解冻后汁液流失、质地改变和重量损失。风冷速冻设备以高速低温气流吹过产品,使其迅速通过约−1 °C至−5 °C的关键温区,并在进入冷库前达到储藏温度。因此,选择合适的速冻设备,需要同时考虑产品品质、产线产能和能源消耗。本指南介绍主要设备类型、产能配置方法,以及询价时应提供哪些信息,帮助供应商准确报价。

简要回答:根据产品和生产流程选择设备类型(批次式速冻间、隧道式、螺旋式或IQF速冻机),根据每小时处理量(kg)、进料温度、目标中心温度和产品厚度确定产能,核实制冷剂与供电条件,并从冻结时间、每kg产品能耗和卫生设计等方面比较供应商,而不只看价格。

速冻与冷冻储藏的区别

冷冻库用于储藏已经冻结的产品,其制冷系统主要按经墙体和库门传入的热负荷配置。速冻设备则需要快速排出较高温度产品中的大量热量,因此采用更低的空气温度(通常为−35至−40 °C)和更高的风速。将温热产品直接放入冷冻库,会造成系统过载,使已储藏产品的温度升高,同时新入库产品的冻结速度也过慢。速冻与冷库储藏指南介绍了两者如何协同运行。

主要速冻设备类型

  • 批次式速冻间或速冻室:将推车或托盘上的产品装入,冻结后再转入冷库。适合分割肉、预制餐食和烘焙食品等多品类生产,灵活性高。
  • 隧道式速冻机:推车或输送带穿过长条形保温隧道,适合中等产量的同类产品。
  • 螺旋式速冻机:输送带在紧凑的围护结构内螺旋运行,适合禽肉分割品、烘焙食品和预制餐食等连续大批量生产线。
  • IQF(单体速冻)设备:采用流化床或网带,将蔬菜、浆果、虾、切丁产品等小块物料分别冻结,使其在包装内保持松散、不结团。
  • 平板速冻机:将产品压置于制冷平板之间,适合鱼块、肉块或果浆块的高效冻结。
  • 各行业应用可参阅速冻设备概览。

如何确定速冻设备产能

连续式速冻设备适合稳定的大批量生产线;批次式速冻间适合多品类产品。

选型首先要明确需要冻结多少产品,以及需要多快完成。关键参数包括: - 处理量:连续生产线按每小时处理量(kg)计算;速冻间按每批处理量(kg)及每天批次数计算。 - 进料温度:刚完成烹煮或高温加工的产品,需要排出的热量远高于已预冷至+4 °C的产品。 - 目标中心温度:转入冷库前,产品中心温度通常需达到−18 °C或更低。 - 产品厚度与包装:厚度增加会显著延长冻结时间;与裸露产品相比,纸箱包装和堆叠包装会减慢冻结速度。 - 产品类型:含水量和密度会影响需要排出的热量。 速冻设备成本计算器和IQF速冻机产能计算器可根据这些参数初步估算所需产能。

制冷系统、能耗与除霜

速冻设备在较低的蒸发温度下运行,因此制冷系统对能耗影响很大。大型工厂常采用氨(NH₃)或CO₂,包括NH₃/CO₂复叠系统,以提高低温工况下的效率;具体对比可参阅NH₃与CO₂制冷选型指南。应要求供应商提供实际工况下每kg产品的冻结能耗、除霜方式与频率(温热且潮湿的产品进入后会迅速结霜),以及风机功率;风机可能占总用电负荷的较大比例。

卫生、安全与运行管理

食品工厂需要能够彻底清洁的速冻设备。应关注不锈钢结构、倾斜表面、开放式网带设计、螺旋式和IQF速冻机的原位清洗系统,以及便于检查的结构。操作人员安全措施包括门体紧急逃生装置、报警系统,以及极低温环境下的安全进出通道。还应规划冻结后产品的转运路线:通过短距离、温控通道进入冷库,可避免转运过程中温度回升。

速冻间、螺旋式还是IQF?快速选型指南

  • 产品种类多、产量适中:批次式速冻间。
  • 包装或未包装产品的稳定连续生产线:隧道式或螺旋式速冻机。
  • 需要保持松散的小颗粒产品(蔬菜、浆果、虾):IQF速冻设备。
  • 扁平的鱼块或肉块:平板速冻机。
  • 许多工厂会组合使用不同设备,例如用IQF设备处理蔬菜,同时配置速冻间应对不定期批次生产。

询价文件(RFQ)应包含哪些信息

应明确产品类型、处理量、进料温度和目标中心温度、产品尺寸与包装、可用占地面积和净高、供电条件与制冷剂偏好、卫生要求、与现有产线及冷库的衔接要求,以及预期供货服务范围(安装、调试、培训、售后服务)。可使用RFQ询价生成器整理需求;ColdMatch Group会在引荐合格供应商前审核每份项目需求。预算规划可参考冷库成本指南中的估算区间。

如何选择供应商

速冻设备属于工程化设备,不同方案的设计假设往往不同。比较报价时,应确认各供应商采用相同的处理量、进料温度、产品中心温度和产品尺寸。应要求供应商承诺实际工况下的冻结时间和产能,而非仅提供样本参数;提供处理类似产品的工厂案例;说明本地服务覆盖与备件库存、交货及安装计划,以及调试阶段的设备测试方法。相比最快给出报价,愿意详细了解产品情况的供应商通常更值得关注。

有助于降低成本的节能措施

  • 在食品安全允许的条件下,先对熟制产品预冷,减少速冻设备需要排出的热量。
  • 在推车和输送带上均匀布料,确保气流能够到达每件产品。
  • 采用变速风机和压缩机,按实际负荷调节运行。
  • 回收冷凝热,用于制备热水或地板下供暖。
  • 按需除霜,而不是仅按固定定时程序除霜。
  • 这些运行细节上的小调整,可在设备整个使用寿命内显著降低每kg产品的能耗。

常见选型与运行误区

  • 用冷冻储藏库冻结温热产品。
  • 按平均处理量而非峰值处理量配置产能。
  • 估算冻结时间时忽略产品厚度和包装。
  • 低估除霜需求和结霜负荷。
  • 只比较价格,不比较每kg产品能耗和卫生设计。
