Rice-hulling and rice-milling combined machine and sample preparation method

Abstract

The invention discloses a rice-hulling and rice-milling combined machine and a sample preparation method utilizing the rice-hulling and rice-milling combined machine. The rice-hulling and rice-milling combined machine comprises a rice hulling machine (20) and a rice milling machine (30) which is positioned below the rice hulling machine (20) and is connected with the rice hulling machine (20) through a rice-hull separation channel (40); a first brown rice outlet (41) and a second brown rice outlet (42) are arranged at the lower end of the rice-hull separation channel (40), a rice and hull outlet (43) is arranged at the other end of the rice-hull separation channel (40) and is connected with an air suction device, the first brown rice outlet (41) is connected with the rice milling machine (30), the rice-hull separation channel (40) is provided with a distribution mechanism (60), and the distribution mechanism (60) is used for opening one of the first brown rice outlet (41) and the second brown rice outlet (42) and closing the other one. By utilizing the rice-hulling and rice-milling combined machine, the switching among various process steps can be conveniently realized, and brown rice or rice samples can be conveniently prepared according to the quality detection needs.

Description

technical field [0001] The invention relates to the preparation of rice or brown rice samples in the quality inspection of rice, in particular to a combined rice huller and rice milling machine and a sample preparation method. Background technique [0002] Husking and rice milling are two important basic processes in the rice processing process. The husking process refers to the hulling of rice by mechanical extrusion and rubbing to obtain brown rice. The rice milling process refers to removing the surface rice skin of brown rice by mechanical milling to obtain finished rice. [0003] In the process of preparing rice or brown rice samples in the traditional rice quality inspection, the husking and rice milling processes are carried out separately, and the husking and rice milling are generally realized in a stand-alone form, and the husker and the rice milling machine are relatively independent and Not related to each other, the operator needs to transfer the brown rice bet...

Problems solved by technology

However, these devices generally can only make rice from rice at one time. When it is necessary to obtain intermediate brown rice samples or only make brown rice into rice samples in applications such as experiments or testing, the function switching operation of such devices is relatively complicated. inability to meet needs conveniently
