Hunan lotus seed screening equipment

Abstract

The invention provides Hunan lotus seed screening equipment. The equipment is characterized in that a screening barrel is divided into a first fan-shaped screen, a second fan-shaped screen and a third fan-shaped screen in the circumferential direction, the aperture of the first fan-shaped screen is larger than that of the second fan-shaped screen, the aperture of the second fan-shaped screen is larger than that of the third fan-shaped screen, a first shielding device is arranged at the first fan-shaped screen, the first shielding device selectively shields and exposes screen holes in the first fan-shaped screen, the second fan-shaped screen is provided with a second shielding device, and the second shielding device selectively shields and exposes screen holes in the second fan-shaped screen. In the specific operation practice, by controlling the opening sequence of the first shielding device and the second shielding device and by means of the centrifugal force principle, Hunan lotus seeds in the screening barrel can be screened according to three hole diameter specifications, the working efficiency is high, screening is uniform, good economic benefits and social benefits are achieved, and the screening equipment is suitable for application and popularization.

Description

technical field [0001] The invention relates to the technical field of food machinery, in particular to Xianglian screening equipment, especially Xianglian screening equipment. Background technique [0002] The most famous lotus seeds in China are Xianglian produced in Xiangtan County, Hunan Province, Jianlian produced in Jianning County, Fujian Province, Xuanlian produced in Xuanping County, Wuyi County, Zhejiang Province, and Ganlian produced in Guangchang, Jiangxi Province. They are called the four major lotus seeds in China. Among them, Xianglian is the most distinctive, and has always been a treasure of tribute to the court, so it is also called "Gonglian" and known as "China's first lotus seed". Later, people gradually expanded the scope of the four major lotus seeds, generally referring to Hunan lotus seeds as "Xianglian". Xianglian, also known as glutinous lotus, is unique in the world in terms of taste. The first crop of lotus seeds is good at selecting full granu...

Problems solved by technology

[0003] After the lotus seeds are picked, they are first screened and graded, and then dried. There are also many lotus screening equipment on the market. However, most of the current lotus seed screening equipment uses a vibrating screen for screening. This screening device uses gravity to make the lotus seeds fall. , because there are many lotus seeds during sieving, resulting in uneven sieving of lotus seeds, resulting in low efficiency of lotus seed sieving
