A kind of crushing walnut kernel extraction processing technology

Abstract

The invention provides a processing technology for crushing walnuts and taking walnut kernels. The processing technology comprises the following steps that firstly walnuts in a feed hopper are pushedinto centrifuging passages of a rupturing container one by one by a material pushing mechanism; then a second transmission shaft drives the centrifuging passages to perform axial high-speed rotation around an annular plate, so that the walnuts perform centrifuging movement, fly off through centrifuging outlets, and collide with sawtooth shaped protrusions to be ruptured; then the ruptured walnutsare discharged downwards to a grinding region in a crushing container by discharging hoppers, a floating regulating mechanism is used for regulating up-down floating of a floating millstone so that the walnuts are effectively clamped between the floating millstone and a fixed millstone, a second transmission shaft is used for driving the floating millstone to rotate to grind the walnuts, and the ground walnut kernels and walnut shells are mutually divorced, and fall to the bottom of the grinding container under the action of centrifuging; and finally, a material falling device is used for receiving walnut shells and walnut kernels, which are divorced at the bottom of the grinding container, and the walnut shells and the walnut kernels are mutually separated and respectively discharged outwards.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to a processing technology for extracting kernels from crushed walnuts. Background technique [0002] China is one of the walnut origin centers in the world, the world's largest walnut producer, has the largest planting area and output, and its export volume is second only to the United States, ranking second in the world. Walnuts have extremely high nutritional value. "Longevity fruit" and "health treasure" reputation, 86% of the fat in walnuts is unsaturated fatty acids, walnuts are rich in copper, magnesium, potassium, vitamin B6, folic acid and vitamin B1, and also contain fiber, phosphorus, niacin, Iron, vitamin B2 and pantothenic acid. In every 50 grams of walnuts, water accounts for 3.6%, and it also contains 7.2 grams of protein, 31 grams of fat and 9.2 grams of carbohydrates. The processing technology of walnuts mainly includes removing green skin, screening and gr...

Problems solved by technology

In every 50 grams of walnuts, water accounts for 3.6%, and it also contains 7.2 grams of protein, 31 grams of fat and 9.2 grams of carbohydrates. The processing technology of walnuts mainly includes removing green skin, screening and grading, cleaning, dehydration, drying, and separation of kernel and shell As well as packaging, the kernel shell separation process is still manually completed at present, and its shelling efficiency is low, time-consuming and laborious. With the intensification of market competition, it is difficult to meet the needs of production development by manual shelling and kernel extraction. Therefore, the inventor designed a A fully automatic centrifugal crushing walnut kernel processing technology with wonderful structure, simple principle, high efficiency of shelling and kernel extraction
