Full-automatic high-concentration beer dilution ratio mixing machine and mixing method thereof

Abstract

The invention discloses a full-automatic high-concentration beer dilution ratio mixing machine and a mixing method thereof, relating to the technical field of multi-material mixing processes such as biology and wine fermentation engineering, food beverage engineering, bio-pharmaceuticals, fine chemistry industry and chemical engineering. The full-automatic high-concentration beer dilution ratio mixing machine comprises a frame, a PLC (Programmable Logic Controller) control cabinet, a static mixer and a diluting pump, wherein the PLC control cabinet is arranged on the outer side of the frame; the static mixer is arranged above the frame; the diluting pump is arranged at the lower end of the static mixer; and the full-automatic high-concentration beer dilution ratio mixing machine is externally connected with high-concentration beer, deoxygenated water, clean CO2 and a finished beer tank. The mixing method comprises the following steps of: mixing high-concentration beer with deoxygenated water in the diluting pump; and mixing with clean CO2 in the static mixer, and feeding into the finished wine tank. The method is practicable; a mass flow meter is applied, so that a reliable precondition is provided for accurate adding of CO2 into diluted beer; a mathematical model is established, so that reliable basis is provided for accurate adding of deoxygenated water and CO2 into high-concentration beer; an open-ring control principle is applied, so that the phenomenon of incorrect mixture ratio caused by hysteresis of feedback adjustment and detection data distortion in closed-ring control is avoided; and automation control in an entire process is realized, so that the labor strength is greatly lowered, the possibility of human errors is lowered, and the product quality and uniformity are improved.

Description

Technical field: [0001] The invention relates to the technical field of multi-material mixing technology of biological and wine fermentation engineering, food and beverage engineering, biopharmaceutical, fine chemical industry, and chemical engineering, especially relates to the dilution of high-concentration beer with deoxygenated water and the dilution of CO in beer. 2 The automatic process control of the addition and flavor blending of Daqu wine. Background technique: [0002] As the market demand for beer with different concentrations and the consistency of beer taste is getting higher and higher, it is required that the raw sugar content of beer can be accurately and flexibly adjusted. At present, in the process of beer production, high-concentration beer dilution and CO 2 The saturation process only uses semi-automatic high-concentration dilution mixer equipment. In the prior art, the CO in the semi-automatic high-concentration dilution mixer 2 Due to many defects in...

Problems solved by technology

In the prior art, the CO in the semi-automatic high-concentration dilution mixer 2 Due to many defects in the design of the flow detection and automatic control system, the concentration of diluted beer and the concentration of CO cannot be guaranteed. 2 The accurate addition and uniformity of the content lead to the taste quality and consistency of beer not meeting the current high standard requirements

The semi-automatic high-concentration dilution mixer used in the prior art has CO 2 Volume flow meters are susceptible to temperature and pressure, CO 2 The mass flow converted from the volume flow measured by volume flow is inaccurate; the closed-loop feedback adjustment control feeds back the downstream detected signal to the PLC, and the PLC controls the upstream regulating valve. Due to the existence of downstream air bubbles, the online detection value is distorted. The semi-automatic control not only increases the labor cost, but also increases the labor intensity and error probability. These defects have a negative impact on the quality and uniformity of the beer produced.
