快速回答

面向苹果、梨、猕猴桃、香蕉和牛油果的气调库(CA)与催熟库规划采购指南,涵盖设备选型、气密性、供应商比选及询价清单。 气调贮藏是在气密冷库中降低氧气浓度、控制二氧化碳浓度,以减缓水果呼吸作用的保鲜方式。与单纯冷藏相比,可将贮藏期延长数月。

要点

  • ▸什么是气调贮藏? 气调贮藏是在气密冷库中降低氧气浓度、控制二氧化碳浓度,以减缓水果呼吸作用的保鲜方式。与单纯冷藏相比,可将贮藏期延长数月。
  • ▸CA、ULO和DCA有什么区别? 常规气调(CA)采用固定的低氧设定值,超低氧(ULO)将氧气浓度进一步降低,而动态气调(DCA)根据水果自身的信号持续调整氧气浓度。
  • ▸哪些水果需要催熟库? 香蕉、牛油果、芒果、木瓜和部分番茄,通常在接近销售市场的地点,通过控温、乙烯和强制气流进行催熟。
  • ▸现有冷库可以改造成气调库吗? 部分情况下可以,但改造时达到所需气密性较难。供应商应在改造前勘查库房,并对压力测试结果作出保证。

果品种植商、包装商和进口商的需求,正日益超出普通冷库的能力范围。需要在采收后八个月或十个月销售的苹果和梨、跨半球运输的猕猴桃,以及必须以恰当色泽送达超市的香蕉或牛油果,都依赖两类专用技术:气调(CA)贮藏和催熟库。两者本质上都是冷藏库房,但增加了气体控制、气密性和工艺自动化要求,因此建筑、制冷系统及供应商合同的技术约定也必须相应调整。本指南介绍这两类技术的作用、适用品种、影响项目范围的因素,以及如何编制采购需求,让合格供应商按统一口径报价。

简要回答:气调贮藏通过降低气密冷库内的氧气浓度、提高二氧化碳浓度,减缓水果呼吸作用,将贮藏期延长数月;催熟库的作用则相反,它利用乙烯、温度和气流控制,按计划让水果均匀成熟。采购时应先明确果蔬品种、处理量、贮藏时长、库间数量和气密性目标,再从气体控制设备、库体结构、制冷系统和服务等方面比较供应商,而非只看某一项设备价格。

气调贮藏的作用

水果采收后仍会继续呼吸,消耗氧气、释放二氧化碳和热量,并逐渐消耗赋予其风味与硬度的糖和酸。冷藏可以减缓这一过程,气调贮藏则能进一步大幅降低其速度。气调库将氧气浓度从正常的21%降至较低设定值,通常根据品种控制在1%至3%之间,同时将二氧化碳维持在受控水平。制氮机、CO₂脱除装置和气体分析仪共同维持整个贮藏季的气体环境稳定。

此外还有更先进的技术。超低氧(ULO)贮藏将氧气浓度降至更接近水果耐受极限的水平。动态气调(DCA)系统监测水果自身的胁迫信号,如叶绿素荧光、呼吸商或乙醇,并持续调整氧气浓度。这些系统可在不采用某些采后化学处理的情况下保持品质,对有机产品项目和农残限量严格的出口市场尤其重要。

哪些果蔬适合气调贮藏或催熟

  • 苹果和梨:典型的气调贮藏品种,长达数月的长期贮藏已是常规做法。
  • 猕猴桃:气调配合乙烯脱除,可在长期贮藏中保持果实硬度。
  • 核果、浆果和樱桃:在运输和销售窗口期采用较短时间的气调贮藏或改良气氛保鲜。
  • 甘蓝、洋葱和部分根菜类:在特定市场中可从中受益,通常采用较简单的气体控制方式。
  • 香蕉、牛油果、芒果和番茄:需要催熟库,而非长期气调贮藏。

各类果蔬的温湿度范围可参考贮藏温度表。请注意,正确的气体设定值取决于品种、产区及采收成熟度。可靠的供应商会先了解这些细节,而不是提供通用参数方案。

催熟库的作用

强制通风催熟库内的香蕉托盘,气囊封住托盘排上方间隙。
强制通风催熟库使气流均匀穿过每个包装箱,让水果达到相同的转色阶段。

催熟库适用于已经达到采收成熟度、但尚未充分成熟,需要在接近销售市场时完成催熟的水果。香蕉是最常见的例子,牛油果、芒果、木瓜和部分番茄也采用同样原理。库内通过升温或降温、定量通入乙烯、通风排出二氧化碳,并使气流均匀地强制穿过每个托盘,让每箱水果在同一天达到相同的转色阶段。

决定催熟效果的关键设计是气流组织。大多数现代催熟库采用压差式或强制通风布局,用篷布或气囊封住托盘排上方的间隙,再由风机抽吸空气穿过包装箱。气流不均会造成转色不一致,进而导致交货被拒收。催熟库通常成组建设,每间容纳固定数量的托盘,便于运营方同时执行不同的催熟计划。

决定项目范围的五大因素

  1. 库间数量与尺寸:气调库单间通常保持较小规模,以便迅速装满并密封,之后仅在销售出库时开启。催熟库则按托盘排数确定规模,以匹配每日发货量。
  2. 气密性:气调库必须通过压力测试;气密库板、密封门、穿透部位密封及呼吸袋均为标准配置。既有建筑改造实现气密性的难度远高于新建项目。
  3. 气体控制设备:制氮机(膜分离式或PSA)、CO₂脱除装置、乙烯脱除装置、分析仪及控制软件。
  4. 制冷与湿度:长期贮藏需要高湿度和低风速;催熟则需要精确降温与稳定控制。
  5. 安全:进入低氧库房具有危险。气体检测、警示标识、入库作业规程和呼吸防护设备必须纳入项目范围,不能事后再补。

围绕采收季规划设施

季节性作物会带来季节性作业高峰。包装中心可能在六周或八周内接收大部分苹果,因此预冷、分选和装库能力必须跟上。应规划每间库每日的装库量、达到设定值所需时间,以及销售季每周可开启多少间库。可使用冷库容积计算器初步估算库容,并用冷负荷计算器校核装库高峰期的制冷能力;这一阶段的负荷主要来自田间热。

供电条件同样重要。除制冷系统外,制氮机和气体脱除装置也会增加用电负荷,而农村包装中心的电网接入容量往往有限。在最终确定库间数量之前,应确认可用供电容量。

常见采购与设计误区

  • 指定气调设备,却未在合同中明确气密性测试目标。
  • 库间建得过大,装满耗时过长,导致水果长时间处于高氧环境。
  • 低估采收季的田间热,导致降温缓慢。
  • 将催熟库当作加装一瓶乙烯的普通冷库。
  • 未将气体安全设备和培训纳入供应商供货服务范围。
  • 直接比较范围不同的方案,例如一份包含控制软件和分析仪,另一份却不包含。

询价文件(RFQ)应包含哪些内容

只有明确库房需要达到的目标,供应商才能准确报价。完善的询价需求应包括: - 果蔬种类、品种及预计年处理量; - 各类果蔬的贮藏时长或催熟周期; - 库间数量、托盘类型及每间托盘数量; - 温度、湿度、氧气、CO₂和乙烯的目标范围; - 新建或改造项目,以及所需气密性标准; - 现场供电容量和气候数据; - 所需控制功能、数据记录和远程监控; - 安装、调试、培训和售后服务要求。

询价文件生成工具可将上述要点整理成结构化需求书。如需了解更广泛的果蔬冷链问题,请阅读果蔬采后冷藏指南;制冷剂选型可参考NH₃与CO₂采购对比指南。

如何比较供应商方案

先统一供货与服务范围,再比较总价。核对各份方案是否包含相同的库体结构、库门类型、气体控制设备、分析仪、软件、制冷能力、安装和调试。要求供应商明确承诺的气密性指标,以及交付验收时的测试方法。同时了解贮藏季可获得哪些本地服务,因为三月份一台气体脱除装置故障,就可能造成整库水果损失。如何比较冷库供应商方案详细介绍了比选方法。成本问题可参考冷库造价指南,该指南采用一个公开发布的基准。
