Embodiment Construction

[0046] The present invention will be further described below in conjunction with the accompanying drawings.

[0047] The inventive method comprises the following steps:

[0048]Step 1. Obtain parameters such as tank production rate, α-amino nitrogen, saccharification power, total soluble nitrogen, β-glucan, and unit price of the main raw materials (including barley malt, special malt, wheat malt, and auxiliary raw materials) in the beer formula. The data can be obtained through the supplier, or through statistics during the production process;

[0049] Step 2. Establish a comprehensive production performance index estimation model based on raw material parameters. The main comprehensive performance indexes considered are maltosaccharification power, wort total nitrogen, wort α-amino nitrogen, wort β-glucan, and lauter tank dross layer thickness.

[0050] ① Maltosaccharification power

[0051] Under normal saccharification operation (saccharification at 65-68°C for 30-45 minu...

Abstract

The invention relates to a method for optimizing a beer production formula. A conventional production formula is determined by a method which combines human experience and tests. The method comprises the following steps of: obtaining main raw materials in a beer formula; establishing a comprehensive production performance index estimation model according to the parameters of the raw materials, wherein main considered comprehensive performance indexes comprise saccharifying power, wort total nitrogen, wort alpha amino nitrogen, wort beta glucan and the thickness of a distilled grain layer of afilter tank; and optimizing a beer formula model by using a variable-metric ant colony optimization method and finally obtaining a production formula with the lowest cost. The method of the inventionhas the advantages of openness, robustness, parallelism and global convergence.

Description

technical field [0001] The invention belongs to the field of information and control technology, relates to automation technology, in particular to a method for optimizing beer production formula. Background technique [0002] The optimal design of raw material formula is an important research content in the fields of chemical industry, food and materials. In order to obtain a formula with excellent performance that can meet the requirements of use, it is necessary to determine the dosage ratio of various raw materials through testing, optimization, identification, and rational selection of raw materials according to the performance requirements and process conditions of the product. In recent years, the research on the application of formulation optimization design has become active. For such a complex multi-objective formulation system, most of them adopt the method of experimental design. The formula design of beer enterprises is no exception. In order to keep the style ...
