Solid-state fermented grain sampling device

Abstract

The invention discloses a solid-state fermented grain sampling device, belongs to the technical field of solid-state fermentation, and provides the solid-state fermented grain sampling device which is simple and convenient to operate and accurate in sampling. The solid-state fermented grain sampling device comprises an extension rod and a sampling body, one end of the sampling body is provided with a conical head cone, the other end of the sampling body is connected with one end of the extension rod, the other end of the extension rod is a holding handle, the sampling body comprises a cylinder body wall and a grain scraping arc-shaped piece, a material containing chamber is arranged in the cylinder body wall, a feeding opening is formed in the cylinder body wall, the vertical edge of one side of the grain scraping arc-shaped piece and the vertical edge of one side of the feeding opening can be in pivot joint fit in a relatively rotating mode through a rotating shaft, and after the scraping arc-shaped piece rotates, the feeding opening can be switched between a closed state and an open state. The feeding opening can be opened and closed by rotating the sampling device after the device is inserted into fermented grains by a specified depth, so that the purpose of accurate sampling is achieved.

Description

technical field [0001] The invention relates to the technical field of solid-state fermentation, in particular to a sampling device for solid-state fermentation grains. Background technique [0002] Solid-state fermentation is a traditional food fermentation method in China, such as solid-state vinegar, sauce, liquor and other traditional industries. Among them, the traditional liquor industry mainly adopts the solid-state fermentation method, using raw materials such as sorghum, wheat, and rice to cook and gelatinize, and then mixing and brewing Daqu and auxiliary materials, bran shells, which are filled into cellars for natural fermentation. 1-year cycle), complex microbial strains, and heterogeneous fermentation, which lead to different quality and flavor of liquor in different regions, and rich varieties. Therefore, the study of traditional solid-state fermentation is more complicated and difficult to study. [0003] In daily production and scientific research, it is o...

Problems solved by technology

However, traditional solid-state cellars are usually larger and deeper. For example, the length, width, and depth of liquor cellars may be 2-3 meters. There are grains, bran shells and other materials in the fermented grains, which have been accumulated for a long time, which has a large Viscosity and the resistance of chaff fibers make it difficult for general samplers to go deep into the cellar, and the operation is laborious and inconvenient. During the sampling process, the distil
