Problems solved by technology

[0003] The conventional koji frame is made of thin-walled stainless steel square tube. During the process of stepping on the koji, when the operator puts the koji frame on the ground and knocks out the stamped koji material from the koji frame, the koji frame It will collide with the ground and make a lot of noise at the same time, especially when many operators work together, the noise generated far exceeds the limit value of occupational noise regulations in my country, and it is easy to cause hearing loss to the operators.

Abstract

The invention discloses a preparation method of a koji liquor koji making frame beneficial to vibration and noise reduction, which comprises the following steps: by taking a metal rectangular pipe as a material, spraying a heat vulcanization type adhesive coating, vulcanizing and solidifying a food-grade rubber damping layer, cutting, filling a sound absorber, welding and plugging to form a square frame structure, and finally welding a port sealing plate, a handle reinforcing plate and a handle, and completing the preparation of the koji liquor koji making frame beneficial to vibration and noise reduction. The damping characteristic of the rubber attached to the pipe wall and the sound absorption characteristic of the sound absorber are utilized, so that the noise performance of the koji making frame is effectively changed, the koji making environment noise of a winery is greatly reduced, and a guarantee is provided for the hearing health of operators.

Description

technical field [0001] The invention relates to the technical field of koji making technology in breweries, in particular to a method for preparing a koji wine making koji frame which is beneficial to vibration and noise reduction. Background technique [0002] Stepping on koji making is a crucial link in liquor brewing. During the process of stepping on koji, the operator places the koji making frame on a flat and solid ground, places the koji materials in the koji making frame and steps on it firmly. After the koji material in the koji making frame is dried and agglomerated, the agglomerated koji material is knocked out from the koji making frame and sent to the fermentation room for fermentation. [0003] The conventional koji frame is made of thin-walled stainless steel square tube. During the process of stepping on the koji, when the operator puts the koji frame on the ground and knocks out the stamped koji material from the koji frame, the koji frame It will collide wi...
