啤酒生产过程的热能消耗除CIP和热水制备外,主要耗能集中在醪液升温、麦汁升温以及麦汁煮沸等工段。实现麦汁煮沸工段节能降耗的技术措施有:回收煮沸乏汽节能,包括采用乏汽冷凝器回收乏汽和采用乏汽压缩机节能;采用新型煮沸系统节能,可采用Merlin煮沸系统节能,或采用柔和煮沸系统节能,或采用Stromboli煮沸系统节能。  相似文献

麦汁加热和煮沸受加热器结垢程度的影响,加热器表面结垢可能会导致各批次的麦汁质量有差异。许多酿造厂已证明这种情况的发生。如果连续生产几锅麦汁而中间不对加热器进行洗涤。污垢层的存在导致热传递受阻,麦汁热负荷增加。实验分析了在不同结垢程度下生产麦汁的含氮物质组成,并指出了克服麦汁质量下降的方法。  相似文献

节能是各个领域中的一个共同重要课题。啤酒工厂之40%的能量消耗在麦汁煮沸过程。探讨合理的麦汁煮沸,以节约啤酒厂的能耗,提高效益,具有重大的现实意义。目前,啤酒厂采用的麦汁煮沸有3大类型:(1)传统的常压煮沸;(2)麦汁釜外煮沸;(3)带能贮系统的低(表)压麦汁煮沸。本文对低(表)压麦汁煮沸做较详细的介绍,并与传统常压煮沸做比较。一麦汁常压煮沸系统常压麦汁煮沸系统由煮沸锅(带加热夹套或内加热器)、搅拌装置、排汽管等所组成。蒸发量每小时约10%。煮沸时间至少需90分钟。因为煮沸锅是敞口的,产生的二次  相似文献

以往认为煮沸强度要达到一定范围才能使麦汁煮沸满足要求,实践显示,只要运用合适的处理方法,低煮沸强度的麦汁同样可以满足要求.根据麦汁煮沸设备的特点,通过优化麦汁煮沸工艺,降低煮沸强度,可达到节能和提高质量的目的.  相似文献

For an efficient wort boiling process, a homogenous wort treatment is important. In this publication a new method for quantifying wort homogeneity is proposed. A differential equation for wort heating was formulated, which was validated by temperature measurements during the heating process. The ratio between calculation and measurements quantifies wort homogeneity. Knowing this parameter leads to a better prediction of the different reactions and processes of wort boiling.

There is a vast repository of knowledge regarding improving beer taste stability via wort boiling. However, as far as we are aware, there are few reports dealing with taste stability improvement in terms of quality characteristics by boiling, under proper conditions, the first wort and second worts separately. In this study, more than 50 brews in a pilot scale brewing facility were conducted to investigate suitable boiling conditions for first and second worts. When the second wort (i.e., the last 10% of the total filtered wort) was kept under a low heat load atmosphere (78°C), casted to the boiling first wort, and then re‐boiled for 10 min, the produced beer exhibited no significant differences compared to that of the general beer in terms of taste stability. However, when an adsorbent (bentonite, silica gel, activated carbon or PVPP) was individually added to the second wort and the same boiling procedure was performed, the oxidized flavour of the forced aged beer, treated with activated carbon, significantly decreased, compared to that of the general brew (level of significance α = 0.01). The data from the chemical analysis and fermentation behavior are presented.  相似文献

This article deals with the impact of a vaporization surface in the brewing industry. The vaporization surface is deemed to have a positive impact on the evaporation quality of unwanted flavour components – especially dimethyl sulphide. Based on physico‐procedural considerations and trials, the current article deduces and verifies that an increased vaporization surface does not have an enhancing impact on evaporation quality.

Steam eductors have the potential for reducing the demand for steam during the evaporation of wort by up to 50% with low capital expenditure and without affecting the process of wort boiling or the flavour of beer. The theory describing the operation of eductors is discussed together with sample calculations for the prediction of performance. A small unit was installed on a kettle in the Holyrood pilot brewery to demonstrate the practicality of the principle and to obtain experience in operation. The unit performed in a manner in keeping with theory and had an efficiency of 90%. There is a great likelihood that the economic advantage of steam eductor systems will be very close to theoretical prediction.  相似文献

麦汁在煮沸过程中过度受热会产生啤酒焦糊味,采用经济煮沸技术,充分脱除DMS,调整蒸发量,降低麦汁局部过热程度,降低啤酒TBA值,不仅可以改善啤酒质量,而且可以节约大量的能源。实验表明,传统煮沸与经济煮沸的TBA差值为4.2,TBA值显著降低;可凝固性氮差值为0.9mg,也明显得到降低,改善了啤酒的口味和风味稳定性;同时节约蒸汽20%左右。  相似文献
