The utility model discloses a scraper concentrator for plant polyphenol production, which comprises a tank body and a scraper mechanism arranged in the tank body. The scraper mechanism comprises a scraper, a rotating shaft and a connecting component. The connecting component comprises at least a set of connecting rod units fixed by the outer sleeve on the rotating shaft and along the axis of the sleeve. The connecting rod unit comprises a connecting rod corresponding to each scraper, and each connecting rod is provided with a connecting rod. The connecting rod of the unit is connected in two parts near the shaft sleeve to form a polygon structure fixed on the outer side of the shaft sleeve; that is, each connecting rod not only forms a fixed connection with the shaft sleeve, but also forms two connections between the connecting rods, which greatly improves the connection strength between the connecting rods, and further enhances the support strength of the scraper fixed at the end of the connecting rod, so that the scraper can withstand higher working resistance. The effect of concentration is proved, and the scraper is not easy to be damaged in the process of scraping film for a long time, and the service life of the whole equipment is greatly prolonged.

植物多酚生产用刮板浓缩器
本技术涉及多酚生产浓缩
,特别涉及一种植物多酚生产用刮板浓缩器。
技术介绍
植物多酚是多羟基酚类化合物的总称,广泛存在于植物中,参与植物生长繁殖过程,为植物带来五彩缤纷的颜色,赋予植物酸、甜、苦、涩的味道,有助于植物防御病原、害虫等危害。植物多酚突起大致要经过以下几个步骤:酯水相转移提取—浓缩—精制转相—干燥,其中的浓缩步骤采取浓缩器进行。多酚生产用浓缩器多采用刮板式浓缩器,又称刮板蒸发器,其外壳内带有加热蒸汽夹套,其内装有可旋转的叶片(即刮板),料液由蒸发器上部沿切线方向进入,由于重力、离心力和旋转刮板刮带作用,溶液在器内壁形成下旋的薄膜,并在此过程中被蒸发浓缩,完成液在底部排出。现有的多酚生产用刮板浓缩器,刮板由转轴带动,刮板在转动过程中会受到浓缩液的阻力作用,这就对刮板与转轴间的连接强度有很高的要求,但现有的刮板多是简单的通过连杆与转轴形成连接,连杆与转轴间也是简单的焊接或其他常见连接方式,连杆与连杆之间不能相互配合形成彼此支撑,结构强度不够高,长时间使用状态下易损坏,有时甚至会对刮板的正常工作造成影响,从而影响浓缩效果。技术 ...
