前言近年来,国内新建了大批采用立式大罐发酵新工艺的中、小型啤酒厂,为了稳定和提高啤酒质量,许多厂已采用微型计算机来控制啤酒的发酵过程。我们为孝感啤酒厂研制的啤酒发酵微机控制系统能完成对22个发酵大缸的温度(上、中、下三点)、压力、液位的自动巡迴检测和自动控制温度和压力。本文重点介绍该系统的几个特点.一、采用直接数字控制系统目前国内研制的啤酒发酵微机控制系统品种繁多,在控制方式、控制算法、选用机型及结构诸方面各不相同,但就控制方式而论,大致有以下四种:(1)操作指导控制系统。完成对发酵过程各种参数的巡迴检测与数据的显示和记
Preface In recent years, a large number of medium- and small-sized breweries in China that use vertical can fermentation have been newly established. In order to stabilize and improve the quality of beer, many factories have adopted microcomputers to control the fermentation process of beer. We developed for Xiaogan brewery beer fermentation microcomputer control system to complete the 22 fermentation cylinder temperature (upper, middle and lower three points), pressure, level automatic tour inspection and automatic control of temperature and pressure. This article focuses on several features of the system.First, the use of direct digital control system Domestic beer fermentation microcomputer control system developed in a wide variety of control methods, control algorithms, selection of models and structure of various aspects, but the control Way, there are roughly the following four: (1) operating instructions control system. Complete the fermentation process of various parameters of the tour test and data display and remember
