Horizontal centrifugal equipment for separating pectins

Abstract

The invention discloses horizontal centrifugal equipment for separating pectins. A rotating drum is divided into a settlement area and a drying area from left to right in an axial direction; a spiral material pusher is arranged in a cavity of the rotating drum; the spiral material pusher comprises a spindle and spiral pushing sheets; the spindle is coaxial with the rotating drum; with equal leads, the spiral pushing sheets are fixedly distributed on the external circumferential surface of the spindle in an axial direction of the spindle; the spiral pushing sheets in the settlement area are distributed with equal circles; a material outlet is formed in the spindle of the settlement area; a liquid phase outlet is formed at the leftmost end of the settlement area; the spiral pushing sheets of the drying area are conically distributed in an axial direction; a solid phase outlet is formed at the right end of the drying area; the ratio between the effective working length and the radius of the rotating drum is more than 4.5; pectin and fruit residue suspension is placed in a centrifugal force field of the rotating drum; the solid phase is settled on the inner wall of the rotating drum and conveyed to the material outlet by the spiral material pusher; the liquid phase overflows out via a spiral passage; and the solid phase and the liquid phase are separated; therefore, a better separating effect is obtained.

Description

technical field [0001] The invention belongs to the field of food manufacturing, and in particular relates to a horizontal centrifugal device for pectin separation. Background technique [0002] Pectin is a kind of polysaccharide polymer compound, and its basic structure is a long chain formed by α-D-galacturonic acid connected by 1,4 glycosidic bonds. As a high-grade natural food additive and health product, pectin is widely used in food, medicine and chemical industries. [0003] At present, the typical production process of solid powder pectin products is as follows: raw material→pretreatment→extraction→solid-liquid separation of pectin and pomace→vacuum concentration→ethanol precipitation→washing→drying→pulverization→finished product. Among them, the equipment used for solid-liquid separation of pectin and pomace is the key equipment. At present, belt filter press and plate and frame filter press are widely used. The structure of the belt filter press is mainly compose...
