The key to brewing lies in fermentation. If fermentation is done well, the quality and yield of the wine will be improved. The fermentation temperature of raw material brewing should be controlled above 20 ℃ and below 40 ℃. Those above 40 ℃ are prone to acid production, and fully automatic stubble drying machines, and even koji seeds. Those below 20 ℃ are difficult to ferment with raw material. The manufacturer of household brewing equipment introduces that at the beginning of fermentation, a fully automatic stubble drying machine should be fully stirred once a day to ensure complete fermentation of raw materials. Generally speaking, when the fermentation temperature is between 20-25 ℃, the fermentation period is 15-20 days; When the fermentation temperature is between 25-30 ℃, the fermentation period is about 12; When the fermentation temperature is between 30-38 ℃, the fermentation period is about 7 days.

全自动晾茬机简述冷却器是换热设备的一类，用以冷却流体。通常用水或空气为冷却剂以除去热量。有间壁式冷却器、喷淋式冷却器、夹套式冷却器和蛇管式冷却器等。冷却器安装方式分为立式冷油器和卧式冷油器，立式冷却器具有所需安装面积小、安装方便等特点。卧式冷油器具有压降较小、水冲击性强等特点，因此根据不同的场地、空间高度、使用性能等要求正确选用立式或卧式冷油器，能更好地满足发电机组及其它设备的需要。

A fully automatic stubble drying machine is a type of heat exchange equipment used to cool fluids. Usually, water or air is used as a coolant to remove heat. There are wall type coolers, spray type coolers, jacket type coolers, and coil type coolers. The installation methods of coolers are divided into vertical oil coolers and horizontal oil coolers. Vertical coolers have the characteristics of small installation area and convenient installation. Horizontal oil coolers have the characteristics of low pressure drop and strong water impact. Therefore, selecting vertical or horizontal oil coolers correctly according to different site, space height, and performance requirements can better meet the needs of generator sets and other equipment.

(1)冷却器打压试验合格后，方可投用，启用前排尽内部存水。

(1) The cooler can only be put into use after passing the pressure test, and the internal water storage in the front row should be exhausted.

(2)检查各倒淋、放空阀是否灵活好用及开关位置，压力表、温度计是否全部装好。

(2) Check whether each drain and vent valve is flexible and easy to use, and whether the switch position is in place, as well as whether all pressure gauges and thermometers are installed properly.

(3)检查基础、支座是否牢固，各部螺栓是否满扣、紧固。

(3) Check whether the foundation and support are firm, and whether all bolts are fully fastened and tightened.

(4)投用时，先投冷流，后投热流。

(4) When put into use, first apply cold flow and then apply heat flow.

(5)在投用冷介质或热介质时，要保证副线畅通，再缓慢开出口阀，检查无问题后开入口阀，一定要缓慢开，憋压。投用过程要注意观察设备变化情况。 冷却器投用后，随着温度压力的变化，可能会出现泄漏现象，应及时进行检查。

(5) When using cold or hot media, first ensure that the auxiliary line is unobstructed, then slowly open the inlet valve. After checking that there are no problems, open the inlet valve. Be sure to slowly open and hold the pressure. During the use process, attention should be paid to observing the changes in equipment. After the cooler is put into use, leakage may occur with changes in temperature and pressure, and it should be checked in a timely manner.
