Diseño de un sistema de molienda para la empresa Heisenbeer

Abstract

The objective of this technical project consists of improving the first part of the production line of the Heisenbeer brewery for which a milling system will be designed, the object of study was studied and the three types of barley Best Pilsen Malt, Best Caramel Munich II and Viking Pale Ale Malt were processed to make craft beer. Screening tests were carried out to determine the initial and final diameters for each of the malts. Through the study, the identification of the chemical composition and the laws of mechanical disintegration, the milling time and the operating parameters were defined, the existing mill in the company was diagnosed, and the appropriate mill for the company's need for expansion in the milling line was concluded and selected, the mill was concluded and selected for the company's need of expansion in the grinding line, the validation by economic feasibility of the design was chosen as a way to demonstrate the correct performance of the equipment compared to others present in the market, taking into account that the company has a net present value of 2727.27. According to the study, the company recovers the investment in 3 years, which indicates that its investment is viable. For the operation of the mill a mechanism of knurled rollers of stainless steel 304 was used, which rotate their axes in the opposite direction trapping the particle and reducing its size, they are driven by speed through a single-phase motor ¾, since it was necessary only to break the sample, not to disintegrate it to powder. It is concluded that the design was the required one and that it fulfilled its objective when working with a power of 30 rpm and with a capacity of 60 lb in hopper which gives a continuous capacity of up to 430 kg/h. The drawings of the system were made in the illustrative program AutoCAD.
