Abstract: The subject invention relates to a type of pipe joints fixing ring, comprising two master fixing blocks, an adjusting bolt connecting the two master fixing blocks, several slave fixing blocks, several connecting levers linking the master and slave fixing blocks, and several rollers fixed inside the master and slave fixing blocks, the inside two surfaces of said rollers are tapered planes, two pipe joints and a center ring with an O-ring that are clamped inside the master fixing blocks and the slave fixing blocks, the surfaces contacting the two joints and the rollers are tapered planes, so that by rotating to adjust the distance between the two master fixing blocks, the tapered planes on the rollers inside the master fixing blocks and the slave fixing blocks will push the tapered planes on the two joints, thus the two joints are securely tightened, to enable such integral features as evenly distributed tightening force, labor-saving tightening process and wider range of applications.

Abstract: A bean sprouts processing apparatus includes a feeding section, a treating section and a separating section arranged in sequence substantially in a horizontal manner. The feeding section includes a receptacle for receiving un-processed bean spouts therein and a conveyor for conveying the bean sprouts to the treating section. The treating section has a sprout tray movably supported on a base with a shaking device arranged between the sprout tray and the base to shake the sprout tray relative to the base so as to separate husks from the sprouts and to break roots of the sprouts and also move the sprouts and the separated husks and broken roots toward the separating section. A cooling device is optionally mounted on the base of the treating section to lower the temperature of the sprouts down to about 3.degree.-5.degree. C. The separating section has a sprout support plate movably supported on a base to receive the sprouts from the treating section.
