Beer Brewing Tech: Malt Crushing
We are a manufacturer specializing in the production of brewery equipment. Today, we will explain the process of malt crushing in the process of brewing beer.
Malt and cereal raw materials (rice, corn, barley, etc.) can be well dissolved after crushing, and the crushing quality plays an important role in the biochemical changes of substances, wort composition, wort filtration and utilization rate of raw materials in the saccharification process.
Theoretically, the finer the malt is crushed, the faster and more complete the dissolution of its contents, and the easier the chemical and enzymatic reactions are, so the best yield can be obtained. However, in the actual production, malt can not be crushed too fine, because malt and starch particles have different properties, malt grinding only needs to reach a certain degree.
Considering the wort quality, the damage degree of wheat bran should be as small as possible.
In addition to cellulose, a series of other soluble substances can enter wort, such as malt polyphenols, bitter substances, silicate and protein. After strong elution, these substances will have adverse effects on the color and taste of beer.Because cellulose is insoluble in water and hardly affected by enzymes, it has little effect on wort.
Wheat bran has toughness, and it has mechanical resistance to the roller of the grinder. It is difficult to grind, especially when the moisture content of malt is high. Wheat bran should not be crushed too fine because it can form a natural filter layer. If the malt is crushed too finely, it will reduce the filtration performance of wort, and even cause serious filtration difficulties. In addition, if the malt is crushed too finely, the volume of material becomes smaller, and the malt powder is closely packed together, it is bound to increase the difficulty of wort outflow and grains washing. When wort filter press is used, the wheat bran can be properly crushed to be slightly finer, which is beneficial to maintaining the uniformity of saccharification. Unless equipped with special wort filtration equipment, the powder can be crushed, which is not limited by the degree of grinding of wheat bran.
The extract of wort mainly comes from endosperm. Endosperm is mainly composed of starch and other carbohydrates and proteins. Only when the components of endosperm are completely dissolved can malt be fully utilized. Therefore, the endosperm should be crushed to be fine, but not as fine as flour, otherwise the permeability of filter grain layer will become poor. For example, the internal composition of malt endosperm is uneven, the hardness of each part of malt grain is different, and the mechanical resistance to roller is also different. Therefore, the malt powder is crushed unevenly.
If you are planning to open a brewery. TIANTAI BrewTech could help you answer your questions and supply the brewery equipment system. We supply 2-150bbl complete beer brewing brewery equipment system including malt milling equipment, brewhouse equipment, fermenters, brite beer tanks, beer bottling machine,beer canning machine, beer kegging machine, hopping machine, yeast propagation equipment.
