Introduction
The Elaboration of the beer is a manufacturing process that is incumbent on enormously to Chemical Engineering. The brewing water suitably must be treated so that their chemical ions and other components adjust to the necessary conditions for the elaboration of a good beer. The recepcionada raw material like the rice, the maize or Malta must be to happen through a process of physical training as it is the milling of the same one. This ground raw material after is dealt in pailas with the brewing water in where by means of times and temperature the conversion of starches looks for in you sweeten ferméntesibles, soon to separate the liquid thus obtained of solids by means of a filtration, this called liquid Maische is boiled and mixed with lúpulo to become a brewing must, which after cooled will be inoculated leavening to take it to him to a fermentation that produces the conversion of you sweeten ferméntesibles in alcohol and carbon dioxide gas. Once carried out the conversion, the separation of the beer and the leavening takes place, to be taken this still green beer to a second rest in where it will be able to acquire the necessary characteristics that they take it to transform itself into a stable and pleasant beer when paladar. In the end one will already become to him to leak with the purpose of eliminating all the leavening signs and can just be given to bottling. During each one of the mentioned stages biochemical changes that are important to control on the basis of determined parameters of temperature, time and based on multiple enzymatic activities take place that are related to the fixed parameters of temperature intimately and time. Due to the variety of here present chemical and biochemical reactions a chemical and biological control in constant and detailed form is urgent. in each one of the stages of the elaboration as they are those of kitchens, fermentation and rest. This ybiológico chemical control must go of the hand with the production not having to exist at no moment a divorce between both parts.
