涼茬機是用來生產(chǎn)釀造白酒的設(shè)備,在生產(chǎn)過程中涼茬機的使用大大提高了工作效率,讓釀酒量大量提高,是現(xiàn)在釀酒企業(yè)使用較多的生產(chǎn)設(shè)備。我們知道在釀酒過程中,會需要用到稻殼,很多人都很好奇為什么要加入稻殼,加入稻殼的原因是什么,需要加多少?
全自動涼茬機下面就分享下釀酒過程中加入稻殼的原因。
The stubble machine is used to produce baijiu. In the process of production, the use of the stubble machine has greatly improved the work efficiency and made the quantity of wine making increase. We know that rice husk will be used in the process of wine making. Many people are very curious about why to add rice husk, why to add rice husk, and how much to add? The reason of adding rice husk in wine making process is shared below.
一、稻殼的理化特性
1、 Physical and chemical properties of rice husk
稻殼是由外穎、內(nèi)穎,護穎和小穗軸等幾部分組成,外穎頂部之外長有鬢毛狀的毛。正稻殼則是由一些粗燥的厚壁細胞組成,其厚度大約24~30微米,稻殼富含纖維素、木質(zhì)素、二氧化硅,其中脂肪、蛋白質(zhì)的含量較低,基于稻谷品種、地區(qū)、氣候等差異,其化學(xué)組成會有差異。
Rice husk is composed of exoglume, endoglume, protective glume and rachis. There are sideburns on the top of exoglume. Rice husk is composed of thick walled cells with a thickness of about 24-30 microns. Rice husk is rich in cellulose, lignin and silicon dioxide. The contents of fat and protein are relatively low. Based on the differences of rice varieties, regions and climate, the chemical composition of rice husk is different.
1、稀釋淀粉含量,沖淡淀粉。
1. Dilute the starch content.
糧食中淀粉含量在65%左右,發(fā)酵入池淀粉控制在17~22%之間。加入稻殼起到?jīng)_淡淀粉作用。
The starch content in grain is about 65%, and the starch content in fermentation tank is between 17% and 22%. Adding rice husk can dilute starch.
2、稻殼具有彈性,起到疏松作用。
2. Rice husk is elastic and loose.
這樣發(fā)酵的糧醅含有一定量空氣,白酒酒曲在有氧的情況下大量繁殖,無氧發(fā)酵,借助稻殼使發(fā)酵的糧醅含有一點點空氣,正好使酵母菌等繁殖起來。
Fermented grains contain a certain amount of air. Baijiu starter is bred in aerobic condition, and is fermented without oxygen. With the help of rice husk, fermented grains contain a little air, which can make yeasts grow.
3、托水功能。
3. Water holding function.
白酒發(fā)酵過程在窖池中進行,有了稻殼可以拖著水,使窖池內(nèi)上下層發(fā)酵均勻,不于上層發(fā)酵的不好,下層水過多。
The fermentation process of Baijiu is carried out in the cellar. With rice husk, it can drag water, so that the upper and lower layers of the cellar can be fermented evenly, not the upper fermentation is not good, and the bottom water is too much.
二、加入稻殼的時間:
2、 Time of adding rice husk:
入窖加入谷殼,可以疏松酒糟,不致入窖糧糟發(fā)粘,還可以降低酸度,利于發(fā)酵。用涼茬機蒸餾時加入谷殼,可以使酒糟攤?cè)鼍鶆颍粔簹?,提高出酒率?/div>
The addition of husk into the cellar can loosen the distiller's grains, prevent the grains from being sticky, and reduce the acidity, which is conducive to fermentation. When distilling with cooling stubble machine, adding rice husk can make distiller's grains spread evenly, do not press air, and increase liquor yield.
三、需要加入多少稻殼涼茬機
3、 How many rice husk cooling stubble machines need to be added
稻殼中含有多縮戊糖,果膠質(zhì)和硅酸鹽等成份,在發(fā)酵過程中影響酒質(zhì),所以其用量要嚴格控制(一般控制在8%比較合適),并且使用前進行清蒸,多縮戊糖在微生物的作用下生成t醛。稻殼要求新鮮、干燥、無霉?fàn)€。
Rice husk contains pentose, pectin, silicate and other components, which affect the quality of wine during fermentation. Therefore, the dosage of pentose should be strictly controlled (generally controlled at 8% is more appropriate), and it should be steamed before use. Pentose can produce t-aldehyde under the action of microorganisms. Rice husk should be fresh, dry and free from mildew.
