亿科新能源辣椒烘干工艺步骤
辣椒烘干工艺关键步骤如下：
一、堆放厚度
辣椒的堆放厚度力求一至，一般20~30厘米为宜，堆放太薄，透气性好，风阻小，虽然有利于热交换，但热空气与辣椒的接触时间相对缩短，热利用率低，若堆放太厚，则阻力增太，热空气无法穿透物层，烘干效果较差。
二、温度的选择
辣椒烘干的热风温度取值如何关系到辣椒的品质和烘干效率，试以辣椒的成份及在某种温度下几种主要成份受到影响的情况进行分析。辣椒含十多种主要营养成份。其中，某些成份在高温下容易遭到损失和破坏，为了不使营养成份降低，故不宜选择较高的热风温度。辣椒烘干机温度20-80℃可调；采用分段干燥法，分段干燥是目前辣椒干燥较优越的方法。
三，分段干燥
分段干燥是目前辣椒干燥较优越的方法，即将含水率75％一85％的辣椒，第一次将辣椒烘干到含水率50％踩堆发汗，再进行第二次烘干。
踩堆发汗在辣椒干燥工艺中是一个很重要的步骤，是否采用这一步骤对辣椒品质和烘干时间、烘干量都有很大影响。辣椒在烘干过程中都有明显的软化和膨胀现象。踩堆发汗的主要作用是调质，使辣椒油向表面渗透，烘干后的辣椒颜色一致，红润光滑，并促使辣椒含水率趋于平衡。如不进行踩堆发汗，烘干1000公斤辣椒，热风温度40℃—60℃时 需时间63小时，踩堆发汗后则可缩短到40小时左右，且花黄壳显著减少。第二次烘干完成后，既可获得超高品质的辣椒干成品了。
农产品烘干机
由于辣椒品质不同，成熟度的差异，个别在第一次烘干作业中不能烘干的辣椒应选出来，进行再烘干。辣椒原料含水率很高，一般为７５％一８５％。用４０—６０℃热风干燥，起初相对温度低于７０％，５小时后相对湿度降到５２％以下，１２小时后，相对湿度就全部低于４０％。
由此可见辣椒降水速度大部分时间都处于内部水份转移的控制之下，因此，辣椒烘干作业生产率主要决定于辣椒本身温度的高低，而不是热风载湿、排湿能力，从保证烘干后辣椒营养成份不受影响及提高生产率的角度综合考虑，烘辣椒热风温度取６０—7０℃为宜。这样可以保证辣椒颜色、香味均属上乘；辣椒的铺放厚度力求一致，堆放太薄，透气性好，风阻小，虽然有利于热交换．但热空气与辣椒的接触时间相对缩短，热利用率低．若堆放太厚．则阻力增大，热空气无法穿透物层．烘干效果较差；辣椒烘干过程结束后，含水率很低，质地焦脆，极易破碎，故应在室内放置进行回潮，使其吸收一定量的水分变软，才能进行包装贮藏。
