原料粉碎方式：

有濕法粉碎和回潮粉碎二種工藝。

濕法粉碎方式：

使麥芽吸水后粉碎，提高麥皮的完整度，提高單位過濾面積的投料承載力，可以送入CO2隔氧，進醪速度和混合的均勻性。但瞬間動力負荷大，粉碎時間要求嚴格。

回潮增濕粉碎：

麥芽吸收水分均勻可調，能最大限度地確保粉碎后麥芽皮殼的完整度，粉碎后的物料可以短時間的貯存，有利于調節粉碎與投料時間的銜接，不需要太大的粉碎能力，瞬間粉碎動力負荷小。

原料粉碎要求：

滿足生產效率的要求，粉碎麥芽的麥皮盡可能完整(提高過濾槽的滲透性，減少有害成分浸出）；淀粉原料的粉碎度達到一定的要求(便于糊化及 α- 淀粉酶的快速分解)。

原料控制要求：

準確可靠的料水比、pH 在線調節，通過變頻控制攪拌速度，自動化控制。

 

Raw materials milling mode: 

Including wet milling and moisture regain milling.

 

Wet milling: 

The milling is carried out after the malt absorbs water, so that the bran integrity is enhanced and the feeding bearing capacity on unit filtering area is improved. CO2 can be fed to isolate oxygen, improving mash charging speed and evenness of mixing. The instantaneous power load is high, so the requirement for milling time is high.

 

Moisture regain milling: 

The moisture absorption by the malt is even and adjustable, so that the bran integrity can be maintained to the utmost extent after milling. 

The materials after milling can be stored for a short period of time, which is beneficial to the connection of milling time and feeding time. The milling capacity is not required to be very high and the instantaneous power load is low.

 

Raw materials milling requirements: 

To meet the requirement for production efficiency, the bran shall be integral whenever possible (enhancing the penetration of filter tank, and reducing leaching of harmful contents). The milling degree of starch raw materials shall meet certain requirements (for the convenience of gelatinization and rapid decomposition of α-starch).

 

Raw materials controlling requirements: 

Accurate and reliable material water ratio, pH online adjustment, controlled through frequency converter, automatic control.
