对于等离子体放电组件与真空容器1之间的固定方式，可选的实施方式下，可以在等离子体放电组件真空容器1之间通过固定支架6相连，即通过固定支架6架起本体2，然后将固定支架6与真空容器1之间进行固定，而对于固定支架6与真空容器1的内壁之间的固定则采用例如但不限于螺栓固定的方式即可。
可选的情况下，屏蔽层4采用2mm厚的304不锈钢制成，聚四氟乙烯为绝缘材料形成绝缘结构的厚度为20mm，放电电极3的长宽高为350mm×100mm×100mm，其中放电电极3的电极板为5mm厚的304不锈钢制成，一组放电电极3之间的纵向距离为60mm。而两个等离子体放电组件的放电电极3之间的横向间距为80mm。两个等离子体放电组件分别包括的一组放电电极3分别与一套射频电源系统17连接，都采用最大功率为1000W、频率 为13.56MHz射频电源，根据需要可实现同时或分时段不同功率下的辉光放电。
为了便于对真空容器1中的等离子体放电单元和真空容器1中的其它部件进行检修，本实施例采用的卧式结构的真空容器1的宽度方向的两端分别设有一个可拆装的封头7，同时为了便于对真空容器1中的枸杞处理过程进行观察，可选在封头7上开有屏蔽式的观察窗。
对于内腔5中空的本体2来说，其中空的内腔5形成的放电空洞适于枸杞通过，一组放电电极3分别位于流通经过本体2内腔5的枸杞的上方和下方。
对于枸杞处理过程中影响枸杞处理效果的一个重要因素在于真空容器1的真空度，本实施例设计了气体调整组件来调节真空容器1中的真空度。具体的，本实施例采用的气体调整组件包括在真空容器1的侧壁设有的出气口8和进气口9；其中，出气口8与一抽气结构10相连；进气口9与一通气结构11相连。此次，可选的抽气结构10可以是一抽气泵，而通气结构11可以用于对真空容器1通入混合气体或者氧气的储气罐，此次例如混合气体，氧气和氦气体积比8:1－2:1。
具体的枸杞是这样进出真空容器1的，在真空容器1上设有一适于将枸杞投入真空容器1中的进料口，进料口连接有一上料斗12；在进料口与上料斗12之间设有上料控制阀13；以及真空容器1上还设有一适于将枸杞从真空容器1中排出的排料口，排料口连接有一下料斗14。进料口位于卧式结构的真空容器1的上方，以及排料口位于卧式结构的真空容器1的下方。
对于进入真空容器1中的枸杞进行传输，并且在传输的过程中进行等 离子体放电处理，实现系统化的枸杞处理程序，本实施例设计的枸杞改性处理装置还包括在真空容器1中设有的用于承载枸杞且带动枸杞沿着真空容器1内腔5运动的输料机构。
可选的情况下，本实施例采用的输料机构包括环形结构的输料带15、与输料带15相连的以驱动输料带15循环运转的动力组件；其中输料带15长度方向的一侧穿过本体2的内腔5，且在输料带15穿过本体2的内腔5后，一组放电电极3分别位于穿过本体2的内腔5中的输料带15的上方和下方。由于枸杞属于食品，本实施例优选采用的输料带15为麻质导布制成。
此处需要说明的是，对于环形结构的输料带15来说，结合卧式结构的真空容器1，环形结构的输料带15的长度方向侧端部沿着卧式结构的真空容器1的长度方向分布，且环形结构的输料带15的两个长度方向的侧端部纵向分布，即此次对于环形结构的输料带15来说枸杞流通的位置只是在输料带15的纵向分布的且位于上方的侧端面上，因此，此次优选的情况下，进料口对应输料带15长度方向的且位于上方的侧端面的一个端部设置，使得通过进料口进入真空容器1中的枸杞直接掉落在输料带15上，而排料口则对应输料带15长度方向的且位于上方的侧端面的另一个端部设置，使得沿着输料带15传输的枸杞在由位于上方的侧端面向输料带15的宽度方向的半弧形部输送的过程中掉落至排料口处。因此，本实施例实际穿过本体2的中空内腔5的即为输料带15的长度方向的且位于上方的侧端部。
一种可选的实施情况下，动力组件包括分别与输料带15的宽度方向的两半圆弧结构相连的一对转动轮16，以及与一对转动轮16中至少一个转动轮16相连的以驱动该转动轮16旋转的驱动器。此处的驱动器采用例如但不限于减速电机，通过减速电机带动一对转动轮16中的其中一个转动轮16 的旋转来实现环形结构的输料带15的循环运转。此处的动力组件可以采用机械领域中惯用的任何一个用于驱动环形结构的输料带15循环运转的结构均可，对此，本实施例不做绝对的限定。
实施例2：
在实施例1的枸杞改性处理装置的基础上，本实施例提供了一种枸杞改性处理方法，采用实施例1的枸杞改性处理装置，具体包括：
步骤S1：调节真空容器1的真空度；具体为，a、打开出气口8和启动抽气结构10，保持真空容器1的真空0.5－2Pa，以去除真空容器1的水分和其他气体等影响因素；b、打开进气口9以及打开通气结构11，向真空容器1内充入氧气(或混合气体，氧气和氦气体积比8:1～2:1)，维持真空容器1抽气、充气状态，使真空容器1内的工作真空度保持稳定在20～40Pa。
步骤S2：将枸杞投放进入真空容器1，使得枸杞在真空容器1中流通；开启上料斗12下端的进料控制阀，使枸杞依序落在传动的输料带15上，依次进入两个等离子体放电组件形成的辉光放电区。此处需要说明书的是，对于上料斗12配置有上密封盖18，使得对于投入在上料斗12中的枸杞形成密封的空间，在真空容器1对于枸杞进行处理的过程中，上料斗12的上密封盖18不会打开。
步骤S3：开启射频电源系统17，实现等离子体辉光放电；对在真空容器1中流通的枸杞进行等离子体处理，此步骤可与步骤S2同步进行，也可在枸杞进入真空容器1前进行。枸杞在真空容器1内等离子体放电组件的一组放电电极3处的处理时间为30-60秒；其中可选的情况下，沿着枸杞流通的方向设置的两个等离子体放电组件，近进料口等离子体放电组件的放电电极3的放电射频功率为100－120W，近排料口等离子体放电组件的放 电电极3的放电射频功率为60－80W。
步骤S4：排出经等离子体处理后的枸杞。对于经过等离子体放电组件处理后的枸杞由排料口排入下料斗14中，对于本实施例的下料斗14设置有下密封盖19，该封盖之后在完成结束真空容器1的枸杞处理后才会打开该下密封盖19。待上料中的枸杞都处理完毕，关闭电源、抽气结构10，对真空容器1中通入空气至大气压，再从下料斗14中取出枸杞。
需要说明的是，对于本实施例的步骤S2和步骤S3的顺序可以调换，也可以是同时进行，以确保流通过程中经过等离子体放电组件的枸杞可以进行等离子体放电处理。
还需要说明的是，对于本实施例设计的枸杞改性处理装置在系统化运行过程中涉及的各功能部件的控制，可以是人为控制启闭，也可以将均连接一上位机，通过上位机来协调启闭各功能部件，对此，本实施例不做绝对限定。
