Intermittent juglans sigillata crushing and shell-kernel separating device and juglans sigillata oil extracting technology

Abstract

The invention discloses an intermittent juglans sigillata crushing and shell-kernel separating device and a juglans sigillata oil extracting technology. The device comprises a crushing chamber shell.A crushing chamber is arranged in the crushing chamber shell. The crushing chamber shell comprises an upper shell and a lower shell, which are connected together. The top end of the lower shell is provided with a semi-circular sieve plate that bends downwards. The upper shell and the sieve plate enclose the crushing chamber. A rotation shaft, which is coaxial with the sieve plate, is arranged in the crushing chamber. Three sets of rotation knifes are uniformly arranged on the rotation shaft along the circumferential direction. A position, which is used to fix the sieve plate, of the lower shell is provided with a fixed knife that is axially parallel to the rotation shaft; the rotation knifes are inclined relative to the fixed knife; one side of the upper shell is provided with a shell outlet, which is above the fixed knife; and one side, which is opposite to the shell outlet, of the lower shell is provided with a kernel outlet, which is arranged under the sieve plate and is communicated with the crushing room through the sieve plate.

Description

technical field [0001] The invention belongs to the technical field of walnut oil processing, and in particular relates to an intermittent iron walnut crushing kernel shell separation device and an oil extraction process for iron walnuts. Background technique [0002] Iron walnut belongs to Juglandaceae, a deciduous tree with a height of 10-20 meters and a life span of more than a hundred years. Distributed in Southwest China and other places; the fruit has a hard shell and can be used to make various beautiful and durable handicrafts; in some places, a large and strange iron walnut is selected for fitness balls. [0003] The iron walnut contains about 80% shell on average, about 20% kernel on average, and about 13% oil on average. Iron walnuts have many shells, few kernels, and low oil content. Using existing crushing and screening equipment to separate the shells and kernels, the kernel content in the shells is relatively high, usually above 5%, resulting in a waste of re...

AI Technical Summary

Problems solved by technology

Another method is to prepare iron walnut oil by boiling. The processing technology is: iron walnut→crushing→boiling→crude oil→filtering→drying and dehydration→finished walnut oil. This process is primitive and backward, and the labor cost is high. The labor intensity is high, the energy consumption of heating and boiling is high, it is difficult to realize the large-scale production of the assembly line, and the yield of walnut oil is low

There is also a method of iron walnut crushin
