果蔬相温预冷兼容多耦合抗衰老处理技术及装备
优先权号：201710584178.9，申请日：2017-07-18，优先权国：中国
技术领域
本发明属于果蔬保鲜领域，具体涉及一种果蔬相温预冷兼容多耦合抗衰老处理技术及装备。
背景技术
果蔬保鲜以采后生理病理为基础，温度、湿度、气体和防腐为手段，其中温度作用率约60％-70％，湿度、气体和防腐各占10％-15％，因此，在不产生冷害或冻害条件下，果蔬保鲜温度越低越好，尽快脱除田间热预冷被定为冷链最先1公里，1851年澳大利亚工程师詹姆斯发明的冷库用于果蔬贮藏被誉为技术第一次革命，1927年英国剑桥大学基德和韦斯特发明的CA(气调)库被誉为第二次革命，也有人说1962年美国布格提出的减压贮藏技术或1972年日本山根昭美提出的冰温库贮藏技术为第三次革命。
其中，冷库依靠机械制冷任意降温恒温，温差±0.5-1℃；CA库在冷库基础上任意调节贮藏环境氧和二氧化碳气体浓度；冰温库与冷库原理相同，但控温精度高达减压技术±0.1℃，但是，冷库、气调库、减压库和冰温库技术的共性缺陷是传热又传质，运行时需要不断地使用加湿器加湿，同时冷风机又不断地除霜。
灵武长枣是宁夏具有地方特色的优良鲜果品种，其果实色艳、肉厚、酸甜可口，富含多种维生素和矿物质，尤其VC含量最高，被誉为活“维生素丸”，有“百果之王”的美誉。灵武长枣采后所带的热量较大，较高的品温会增加长枣呼吸强度，最终导致衰老和变质，预冷是保持灵武长枣品质，延长货架期的重要手段之一，通过预冷可以减少产品损耗，节省能源，但是传统冷库库体大，对果蔬数量要求较高，且大量果蔬同时预冷时预冷效率低，预冷耗时长，耗能大。
预冷不能防腐、防霉，在密闭环境下，密闭不能降温，预冷10个小时，黄金处理时间是10小时之内，同时完成防腐防霉，在黄金时间内完成预冷和防腐防霉防衰老。
现有技术的不足之处在于：
1、现有冷库多为静置预冷，传热传质慢，冷量利用率低，预冷耗时长，易造成水分散失；2、果蔬处理方式多为先进行果蔬预冷处理。待处理完后进行保鲜剂处理，容易错过果蔬最佳保鲜期；3、传统隧道差压预冷仅有一种降温方式，无法针对果蔬的品种选取特定的降温方式，如灵武长枣在高温高湿的环境下采取快速降温的方式易产生凹斑病；4、现有技术中预冷中不能加保鲜剂，预冷同时不能加保鲜剂，原因是传热传质。保鲜剂不能起作用，1-MCP，人进去有毒，本申请中每剁都是密闭的独立空间，单元操作。5、传统预冷技术第一大缺陷是传热又传质。冷库静止预冷、差压隧道风预冷、冷水预冷、真空预冷等果蔬预冷技术，共性特点是果蔬预冷降温的同时也不断地失水，预冷过程中降温速度越快失水量越大。6、传统预冷技 术第二大缺陷是环境开发，预冷与抗病抗衰老处理不能兼容。基于上述第一个预冷传热传质缺陷，果蔬预冷过程中，即使是全封闭性箱式工艺技术，制冷系统的冷风机强化换热的同时也吸附环境相的水分、生理调节剂、防腐剂等介质，致使果蔬预冷与抗病抗衰老处理不能兼容执行，也就是说因为降温优先不得不牺牲抗病抗衰老最佳时间，比如乙烯拮抗剂1-MCP(1-甲基环丙烯)最佳处理时间是采后24小时内，而果蔬预冷最佳时间也是采后24小时，因而，不得不选择先预冷再1-MCP处理。7、传统预冷技术第三大缺陷是气调、减压和冰温精准控温不能协同，也就是说气调和减压的同时不能满足较大换热量的精准控温。

为解决上述技术问题，本发明采用的技术方案是：
一种果蔬相温预冷兼容多耦合抗衰老处理设备，包括冷库，在冷库内放置多个差压预冷装置，差压预冷装置的结构为：包括气密封隧道预冷箱，在隧道预冷箱内上部与顶壁间隔平行固装一隔板，隔板延伸至隧道预冷箱底部，隔板的一侧与箱体侧壁间隔平行固装一通风板，隔板另一侧端部垂直向下安装一段挡风板，在隧道预冷箱的一个转角安装轴流风机，该转角为隔板与通风板之间的转角，轴流风机的进风口对应隔板上部空间，出风口对应通风板与隧道预冷箱之间的空间；
在隧道预冷箱内设置多个果实框架，位于通风板与挡风板之间，果实框架上叠放灵武长枣果实框；
在隔板上部的隧道预冷箱上臂，阵列密封安装多排真空换热管，真空换热管的一端位于隧道预冷箱内，一端位于冷库内，将冷库内的低温通过真空换热管导入到隧道预冷箱内，实现隧道预冷箱内气密调节下的快速降温；
在隔板上部靠近轴流风机的一侧安装个超声波雾化器，超声波雾化器内填充保鲜剂溶液， 在冷风循环的过程中，将风机将保鲜剂循环到隧道预冷箱的每一个角落；在气密封隧道预冷箱设置臭氧发生装置和紫外杀菌装置；
所述保鲜剂成分为：茉莉酸甲酯1～3份，特克多2～3份、过钠氧化氢2～3份，水杨酸2～3份、1-MCP0.5-1份。
而且，所述超声波雾化器内喷出的保鲜剂溶液微粒的大小为范围0.5-0.8μm。
而且，挡风板的长度为通风板长度的1/3。
而且，保鲜剂的制备步骤如下：将各组分安装重量份数取原料，用水溶解，加水量为80-100份。
而且，所述隧道预冷箱为塑料大帐或采用保温板制作的隧道预冷箱侧壁。
而且，超声波雾化器内喷出的保鲜剂溶液微粒的大小为范围0.5-0.8μm。
本发明具有积极有益的效果：
1、本发明在差压预冷装置上部装有换热管，轴流式排风机从货堆吸收热，热风进入通风管道，换热管将冷库中的冷风与货物中的热风进行交换，可显著提高预冷效率。
2、本发明在预冷的同时在货物中加入分子插层占位功能的保鲜剂，预冷的同时对货物进行保鲜处理，可明显缩短贮藏前处理时间、提高货物保鲜期。
3、本发明改变传统隧道差压预冷装置采用全封闭的形式，用热管不传质，能够把保鲜剂封闭起来，防止保鲜剂挥发，减少预冷过程中货物水分流失、减少预冷过程中冷量散失，加快预冷效率。
4、本发明采用全密闭形式，减少货物水分流失，是静止遇冷得2-3倍，减少冷量散失，在传统隧道差压预冷装置基础上加入换热管，可显著提高预冷效率，比静止预冷提高3-5倍，比开放式差压预冷提高近1倍。在预冷时加入保鲜剂，缩短贮藏前处理时间缩短2倍，货物保鲜期延长1.5倍。显著增加货物的保鲜期
5、本装置为全密闭状态，隧道上端安装有真空换热管，真空管贯穿通风管道伸入隧道内，轴流式排风机抽取隧道内的热风经过换热管，换热管将隧道外冷库冷风与隧道内货物热风进行交换，促使隧道内温度不断降低，形成一个密闭内循环状态，可以明显加快预冷效率，恒温，不加湿，节省能耗。
6、本发明在预冷的同时在预冷装置中加入保鲜剂，高效热传递和预冷黄金期间加入保鲜剂，通过装置密闭内循环，对预冷货物进行保鲜剂处理，达到预冷的同时对货物进行保鲜处理的效果，可明显缩短贮藏前处理时间、提高货物保鲜期。
7、本发明预冷能够快速降温，针对不同果蔬品种有针对性的设定装置的降温速率。
8、传热不传质。制冷系统与预冷降温体系相互独立，果蔬预冷体系气密不保温，其中降温时热量强制交换依靠换热管和轴流风机强制对流协同实现。
9、降温与抗病抗衰老多兼容。预冷降温体系只有热量强制交换，没有介质相互交换或转移，因而，可以在果蔬采后第一时间内，开展预冷同时进行拮抗剂如1-MCP、诱抗剂如茉莉酮酸甲酯、抗病剂如氯化钙、杀菌剂如二氧化硫、臭氧，或物理如静电、电场等保鲜处理，保鲜剂可以是气体，也可以是液体纳米雾化气体。
10、降温与气调、减压和冰温精准控温协同。预冷降温同时可以像气调库一样任意调节气体成分，减压库一样调节压力和冰温库一样温度波动≤±0.1℃。

具体实施方式
以下结合具体实施例进一步阐述本发明。下述实施例中所涉及的方法，如无特别说明均为常规方法。
一种果蔬相温预冷兼容多耦合抗衰老处理技术及装备，整个装备的机构包括冷库11，在冷库内放置多个差压预冷装置，差压预冷装置的结构为：包括气密封隧道预冷箱3(不保温)，在隧道预冷箱内上部与顶壁间隔平行固装一隔板5，隔板延伸至隧道预冷箱底部，，隔板的一侧与箱体侧壁间隔平行固装一通风板6，通风板上均布通气孔，孔距5cm*5cm每个，直径1cm，隔板另一侧安装一挡风板12(孔距20cm*20cm每个，每个直径为1cm)，用于防止循环风从隔板端部倾斜穿过，在隧道预冷箱的一个转角安装轴流风机4，该转角为隔板与通风板之间的转角，轴流风机的进风口对应隔板上部空间，出风口对应通风板与隧道预冷箱之间的空间，流风机开启后，风从通风板穿出，流经枣框，再循环至隔板上部，经过枣框后流出，在返回到隔板上部空间，完成一轮降温循环，实现其在隧道预冷箱内的循环，由于隔板和通风板的存在，在遇冷箱体内上下部产生差压，能够提供循环速率，促进气体循环。
在隧道预冷箱内设置多个果实框架8，位于通风板与挡风板之间，果实框架上叠放灵武长枣果实框7，可设置多排，每排竖直叠放多个，可以实现大批量的一次预冷。其中，挡风板的高度为通风板长度的1/3。
在隔板上部的隧道预冷箱上臂，阵列密封安装多排真空换热管1(5平方厘米每个)，真空换热管的一端位于隧道预冷箱内，一端位于冷库内，将冷库内的低温通过真空换热管导入到隧道预冷箱内，实现隧道预冷箱内气密调节下的快速降温，在通过轴流风机的循环，将冷气迅速循环到果实框内。热管通过固定架2固装在隧道预冷箱上。
在隔板上部靠近轴流风机的一侧安装个超声波雾化器9，超声波雾化器内填充保鲜剂溶液，在冷风循环的过程中，将风机将保鲜剂循环到隧道预冷箱的每一个角落，超声波雾化器内喷出的保鲜剂溶液微粒的大小为范围0.5-0.8μm，该大小的微粒能够促进灵武长枣表面的微孔对保鲜剂的吸收，提高保鲜效果。
本申请在隧道预冷箱内层放置一层吸收层10，用于吸附过多的保鲜剂液滴，吸附后，通过清洗吸附层，多余的保鲜剂还能够重复使用，整个装置形成一个全密闭环境。与现有技术的敞开式预冷，具有完全不同的效果，敞开式预冷是不能够加入保鲜剂的，本申请首次完成了再遇冷阶段保鲜剂与果实的深度接触，完成预冷和保鲜两个过程。
所述隧道预冷箱的可以铝板、钢板，厚度1-2mm，为了防止预冷箱倾倒，可以在冷库内设置支撑龙骨13。起到隧道预冷箱的固定和支撑的作用。预冷箱长度和高度如图中表示，宽度2.5-2.6米，热管深入到隧道预冷箱内40-50cm。
真空换热管进行热量交换；长龙堆垛由数筐枣组成；真空换热管尺寸为(外径×壁厚)为φ19mm×2mm，长度为80-100mm，材质为碳钢，内部真空。真空换热管结构为：一根密封的金属管，管内壁覆盖一层有毛细结构的材料的做成的芯网，其中间是空的，管内装有一定的热载体(液氮)。
真空换热管原理：真空换热器当受热端开始受热时，管壁周围液体瞬间汽化，产生蒸汽，此时这部分压力就会变大，蒸汽流就会在压力的牵引下向冷凝端流动，蒸汽流到达冷凝端后冷凝成液体，同时也会放出大量热，最后借助毛细力回到蒸汽受热端完成一次循环。
轴流式排风机额定风量为11000m 3/h，风速为1.6m/s，营造的压差为0.16Pa。每小时风量为隧道预冷箱体积的40-60倍。总换热量为每小时、每立方80-100瓦。
上述装置中还可以加入臭氧发生装置14，能够库内的对果实进行臭氧杀菌。还可以安装一个紫外杀菌装置15，对循环空气进行杀菌。
上述预冷系统中，差压预冷装置在进行预冷1-2小时后，在超声波雾化器中加入分子插层占位诱导保鲜剂，成分如下，以质量份计：茉莉酸甲酯1～3份(防冷害，细胞膜完整性)，特克多2～3份(防腐)过钠氧化氢2～3份(杀菌，细菌和真菌)，水杨酸2～3份(防老化、雾化效果)、1-MCP0.5-1份(防衰老，乙烯拮抗剂，抢靶位，乙烯起不来作用)。
上述保鲜剂的制备步骤如下：
将各组分安装重量份数取原料，用水溶解，加水量为80-100份，调节pH至8左右。经过超声后形成恢复性气体，与隧道预冷箱内循环的风一起循环，完成对灵武长枣的保鲜剂覆盖。
保鲜剂的使用方法如下：
本装置能够能够保证能够将第一时间摘得的大枣放入的保鲜库中，保证时时刻刻的新鲜，锁住时时刻刻的水分，以灵武长枣为例，通过本冷库保险后，以灵武长枣为例，保鲜过程中的相关参数如下：
湿度测定：经试验验证，使8吨货物内部湿度与外度湿度达到平衡，静止预冷需10个小时，开放式差压预冷需8小时，本发明所涉及的简约差压预冷仅需5小时。是静止遇冷得2-3倍。
温度测定：经试验验证，使8吨货物由20℃降低至0℃，静止预冷需要24小时，开放式差压预冷需要13小时，本发明所设计的简约差压预冷仅需8小时，简约差压预冷装置遇冷效率比静止预冷提高3-5倍，比开放式差压预冷提高近1倍。
果实失重率：经试验验证，预冷8吨货物，静止预冷果实失重1.05％，开放式差压预冷果实失重0.83％，简约差压是预冷装置果实失重0.65％。显著优于其他两种遇冷方式。
通过实验发现，本发明加入共激发型生物诱抗保鲜剂后，可显著缩短贮藏前处理时间，时间缩短2倍，未加保鲜剂灵武长枣保鲜时间为30天，加入保鲜剂后长枣保鲜时间增加到90天，货物保鲜期延长3倍。
