Description

Combined fermentation container for solid brewing and use method and application thereof

Technical Field

The invention relates to the technical field of solid brewing, in particular to a combined fermentation container for solid brewing and a use method and application thereof.

Background

The traditional brewing technology belongs to labor-intensive industries, and the process links of raw material cooking, spreading for cooling, retort distillation, material mixing and the like in the domestic brewing industry at present basically realize automation, but the process links of cellar entering (jar) and cellar leaving (jar) are limited by the characteristics of a cellar pool and a ground jar, and the automatic operation of the two process links of cellar entering (jar) and cellar leaving (jar) cannot be realized.

At present, fermentation containers in domestic white spirit production are mainly in the form of underground cellars or buried jars. The volume of the underground cellar pool is from several cubes to dozens of cubes, the volume of the earth cylinder is generally within 3 cubes, and manual or travelling grab buckets are adopted for the operation of discharging from the cellar (cylinder) and entering the cellar (cylinder). But the underground pit (cylinder) is adopted for carrying out, the labor intensity of manual work for discharging the pit is high, and the automatic transformation is not convenient. Meanwhile, the volume of a single pit is not too large or too deep, otherwise, fermentation heat dissipation is influenced, the yield is influenced, and the land area required by unit yield is large.

Accordingly, there is a need for a modular fermentation vessel for solid state brewing and a method of using the same that ensures product quality for automated operation.

Disclosure of Invention

The invention aims to overcome the defects of the prior art and provides a combined fermentation container for solid state brewing and a using method and application thereof, so as to reduce labor intensity, control temperature and improve the quality of brewed products.

The purpose of the invention is realized by the following technical scheme: a combined fermentation container for solid brewing comprises a plurality of box bodies which are sequentially and vertically arranged, wherein the top of each box body is provided with an opening, the peripheral outer walls of the box bodies are provided with temperature control devices, and the adjacent box bodies are connected through a sealing fixing piece; the temperature control device can be a temperature control device or a heat preservation device for adjusting the temperature, and can be determined according to the fermentation conditions of the solid brewing products.
