Description

一种土豆贮藏保存方法
技术领域
本发明是针对薯片行业土豆贮藏方法的改进，尤其涉及一种可长期保存，而不影响土豆品质的，安全可靠，损耗率低的方法。
背景技术
目前薯片行业土豆贮藏基本采用常温库保存，由于库内温、湿度随着室外温度的变化而变化，达不到土豆贮藏的最佳温湿度，由于土豆收获期在夏季，气温较高，如果温度太高，土豆内的淀粉会转化为糖份，糖份太高薯片油炸时颜色会发黑，口味会变苦，如果湿度太低，则会造成土豆水分蒸发，土豆皮会变绉、变韧，削皮机无法正常工作。长期保存时，每年库损率高达9%以上，随着薯片行业技术的发展，消费者消费观念和要求的提高，目前采用常温保存已经不能满足要求，急需开发一种满足薯片行业土豆贮藏的方法。
发明内容
本发明目的在于克服现有技术的不足，提供一种能够可长期保存，而不影响土豆品质的，安全可靠，损耗率低的方法。
为实现本发明目的，提供了以下技术方案：一种土豆贮藏保存方法,其特征在于包括以下步骤：
每吨土豆贮藏送风量保证在30m3/h~50m3/h；
入库时温度控制阶梯，土豆进库时保持库区温度在20~25℃的范围内，直至库区堆满土豆，然后24小时内把库区温度降至18℃，湿度保持在≥90％以上，以后每24小时降温0.5℃，直到库区温度降至12℃，湿度保持在≥95％以上；
库区保持长期贮藏需要的最佳温度12℃，湿度湿度≥98％；
通过调节室外新风，把二氧化碳的浓度控制在2500PPM以内，并且库区内保持10~25pa的正压；
土豆每间隔6个月杀虫及打抑芽剂一次，控制库区的虫口数量及抑制土豆发芽。
本发明有益效果：库区采用温、湿度及二氧化碳控制，土豆可以长期存放，而不影响土豆品质的，安全可靠，每年库损率可以由原来的9%降至3%。库容量按1500吨计算，土豆按6元/kg计算每年可以减少损失54万元人民币，具有巨大的社会经济价值。
具体实施方式
实施例1：一种土豆贮藏保存方法,包括以下步骤：每吨土豆贮藏送风量保证在30m3/h~50m3/h；入库时温度控制阶梯，土豆进库时保持库区温度在20~25℃的范围内，直至库区堆满土豆，然后24小时内把库区温度降至18℃，湿度保持在≥90％以上，以后每24小时降温0.5℃，直到库区温度降至12℃，湿度保持在≥95％以上；库区保持长期贮藏需要的最佳温度12℃，湿度湿度≥98％；通过调节室外新风，把二氧化碳的浓度控制在2500PPM以内，并且库区内保持10~25pa的正压；土豆每间隔6个月杀虫及打抑芽剂一次，控制库区的虫口数量及抑制土豆发芽。
对于本领域技术人员来说，在本专利构思及具体实施例启示下，能够从本专利公开内容及常识直接导出或联想到的一些变形，本领域技术人员将意识到也可采用其它方法，或现有技术中常用公知技术的替代，以及特征的等效变化或修饰，特征间的相互不同组合，例如土豆贮藏需要的送风量改变，进库时温湿度的改变，二氧化碳的浓度的改变，等等的非实质性改动，同样可以被应用，都能实现本专利描述功能和效果，不再一一举例展开细说，均属于本专利保护范围。
