Sake preparation system and preparation technology thereof

Abstract

The invention provides a sake preparation system and a preparation technology thereof. The preparation system comprises a rice smashing system, a gelatinizing and liquefying tank, a pre-fermentation system and a post-fermentation system, wherein the rice smashing system is used for smashing rice in water into rice slurry, the gelatinizing and liquefying tank is communicated with the rice smashingsystem and the pre-fermentation system, and the gelatinizing and liquefying tank is used for gelatinizing and liquefying the rice slurry in multistage stirring to produce liquefied feed liquor; the pre-fermentation system comprises a mixing tank, a distiller's yeast tank and a fermentation tank; the mixing tank is communicated with the gelatinizing and liquefying tank and the distiller's yeast tank, the liquefied feed liquor in the gelatinizing and liquefying tank and distiller's yeast in the distiller's yeast tank are mixed in the mixing tank, the fermentation tank is communicated with the mixing tank and the post-fermentation system, and the post-fermentation system is used for wine boiling, wine storing, filtering and sterilizing work procedures for preparing sake. Therefore, a sake preparation technology is improved, a brewing efficiency is improved, labor and site construction cost is reduced, and market competitiveness is improved.

Description

technical field [0001] The invention relates to the field of sake brewing, in particular to a preparation system suitable for sake and a preparation process thereof. Background technique [0002] Sake is made from rice as the main raw material through koji making, distiller's brewing, fermentation, storage and brewing. The degree is generally around 13-15 degrees. The color of the wine is transparent, and the taste can be divided into sweet and spicy. [0003] The traditional sake preparation method includes steps such as washing rice and soaking rice, steaming and cooling, raw material ratio and feeding, fermentation, storage and brewing. Among them, rice washing and soaking refers to agitating and transporting the rice, soaking the rice for a whole day and night, then steaming the rice with a rice steamer, and spreading it to cool down. The rice and water are transported to the tank, and the wine mother is put in many times, and then fermented and stored for brewing. The...

AI Technical Summary

Problems solved by technology

The gelatinization and liquefaction steps are relatively complicated. The transformation of rice from rice grains to rice milk requires a large investment of manpower and site construction, which increases the manufacturing cost of sake and is not conducive to large-scale production, making domestic sake preparation less, and domestic sake preparation technology is still not perfect.

The way of rice gelatinization and liquefaction is still using the old method of soaking rice, steaming rice, cooling, and the brewing efficiency is low
