Abstract

The invention relates to the field of wine brewing equipment, solves the problem that a traditional grain crusher cannot fully crush grains, and provides a multistage grain crushing device. The multistage grain crushing device comprises a shell; a feed port is formed in the upper end of the shell; a crushing cavity is formed in the shell; a crushing mechanism is arranged in the crushing cavity; a screen is arranged at the upper part of the crushing cavity; the crushing mechanism comprises multiple rotating shafts vertically arranged; single rotating shaft is axially provided with blades for grain crushing at intervals; the blades are provided with through holes for enabling the grains to pass through; the through holes in the multiple blades are arranged oppositely; the apertures of the through holes are reduced along with reduction of the heights on the rotating shafts; the blades on two adjacent rotating shafts are staggered, and the through holes in the previous layer of blades are positioned rightly above the blade edges of the next layer of blades; the blade edges of the previous layer of blades are positioned rightly above the through holes in the next layer of blades; the blades in the highest place are positioned below the screen; and the crushing mechanism can generate upward air currents.

Description

technical field [0001] The invention relates to the field of brewing equipment, in particular to a multi-stage grain crushing device. Background technique [0002] Wine making is the process of using microbial fermentation to produce alcoholic beverages with a certain concentration. When making wine, the equipment used usually includes fermentation tanks, pulverizers, distillation equipment, filtration equipment and wine storage tanks. Among them, the grinder grinds other grains except rice because after the grains are crushed, they can fully contact with the koji. In this way, theoretically, the grains can be more evenly and thoroughly fermented. [0003] Most of the existing grain grinders use a blade mechanism in the housing. After the grain enters the upper feeding port into the housing, the blade mechanism is activated to grind the grain, and then it is discharged out of the grinder through the lower discharge port for further processing. next step. However, in order ...
