Continuous feed Aloe vera whole gel extraction equipment comprises of six major components, (a) Outer frame to hold functional components; (b) Conveyor belt; (c) Drive mechanism for gel extraction system; (d) Whole gel extraction mechanism; (e) Collection trays for extracted gel and rinds; (f) Motor. Leaf base and sharp spines of matured Aloe vera leaves are removed before feeding into equipment. Combination action of sliding bearing (4 numbers) mechanism and pressure springs (4 numbers) helps to adjust gap between pressure roller assembly and flatten curvature of Aloe vera leaves. Two high carbon steel blades one each, just above bottom set of rollers and just below top set of rollers, simultaneous peels off both top and bottom rind in a single pass. To obtain whole gel recovery of more than 98.13 ± 0.52 % and residual gel percentage of below 1.87 ± 0.27%, speed of the rollers was optimized at 100 rpm for three levels of leaves thickness (<25 mm, 25–30 mm and >30 mm). Capacity of equipment is 215.00 ± 9.08 kg/h. Percentage saving in cost and time of operation is 55.56 and 70 %, respectively. Quality parameters of whole Aloe vera gel were at par with preferred hand filleting method of gel extraction. Equipment is suitable to be adopted as a rural technology specially in the Aloe vera catchment area.

芦荟全凝胶提取连续进料设备的研制

连续饲料芦荟全凝胶提取设备包括六个主要组成部分:(a)用于容纳功能性组件的外部框架;(b)传送带;(c)凝胶提取系统的驱动机构;(d)整个凝胶提取机制;(e)用于提取胶和果皮的收集盘;(f)马达。将成熟的芦荟叶的叶基和尖刺除去,然后再送入设备。滑动轴承(4个数字)机构和压力弹簧(4个数字)的组合作用有助于调节压力辊组件与芦荟叶片扁平曲率之间的间隙。两个高碳钢刀片各一个,分别位于底部辊组的上方和正上方辊组的下方,一次即可同时剥离顶部和底部果皮。要获得大于98.13±0.52%的整体凝胶回收率和小于1的残留凝胶百分比。87±0.27%,对于三种厚度的叶片厚度(<25毫米,25–30毫米和> 30毫米),滚筒的速度在100 rpm下进行了优化。设备产能为215.00±9.08 kg / h。节省的成本和运营时间分别为55.56%和70%。整个芦荟凝胶的质量参数与首选的凝胶提取手工倒角方法相当。设备特别适合在芦荟集水区用作农村技术。
