Method for separating shells and kernels in leftovers of manually-peeled pecans

Abstract

The invention relates to a method for separating shells and kernels in leftovers of manually-peeled pecans, comprising the following steps: separating the shells and the kernels in the leftovers of raw pecans without being cooked, and separating the shells and the kernels in the leftovers of the cooked pecans. According to scientific research, the relevant characteristics of food additives such as dietary alkali and the like and the principle of differences of the density, the specific gravity and the buoyancy force of the shells and the kernels of the pecans in solution are utilized, the differences of the density and the buoyancy force of the shells and the kernels in the leftovers of the pecans in separating liquids A, B and C are adjusted by preparing the separating liquids A, B and C, so that the separation of shells and kernels in the leftovers of the raw pecans without being cooked, and separation of the shells and the kernels in the leftovers of the cooked pecans need to be matched with a sieving machine, a sieving mesh or the like, and simultaneously the separating liquids A, B and C can be used repeatedly. In the method, the separating effect is good, the adaptability ofraw materials is strong, the operation is simple and convenient, the consumption time is short, the separating cost is low, the kernels are safe to eat, and the original flavor is not changed, so that the method is applicable to processing enterprises of manually-peeled pecans.

Description

technical field [0001] The invention relates to the technical field of hickory nut processing, in particular to a method for separating shell kernels of hickory nut leftovers by hand. Background technique [0002] Hickory (Carya cathayensis) is a famous dried fruit and woody oil crop in China. It has high economic value and is mainly distributed in 29°~30°N, 118°~120°E, namely Ningguo, Shexian, Jingde, Anhui. , Jixi and Lin'an, Chun'an, Anji, Tonglu and other counties and cities in Zhejiang. Pecan kernels are crispy and delicious, rich in nutritional value, contain various trace elements, have the effects of moistening the lungs and nourishing, can also reduce blood lipids, prevent cardiovascular and cerebrovascular diseases and other human health care. [0003] After searching, on May 16, 2002, Wang Xinchang, Shunxi Village, Qingliangfeng Town, Lin'an City, Zhejiang Province, applied for the invention patent 02119416, the publication number is: CN1380014A, and the classifi...

AI Technical Summary

Problems solved by technology

For the shell kernels with larger particle size, manual selection and separation have been used all the time, but there has been no way to remove the shells and impurities in the relatively fine leftovers, so that these hickory kernels mixed with shells and impurities cannot be reused. The price of walnut products is higher, which brings greater economic losses to the enterprise

Retrieval of relevant prior art has not yet found a method capable of effectively separating hickory nut shell kernel waste
