做速冻生包子需要什么样的设备
http://www.skgj.net/data/attachment/forum/201904/12/222902wttmrvrt7ltho7or.jpg一、 开篇
要做好速冻生包子,那么就要选择适用的设备。好马配好鞍,好船配好帆,技术和设备相配才能相得益彰。很多人速冻总是不成功,或许就是在速冻设备的选择上就错了。
二、 设备选择不合理对产品造成的影响
如果有人告诉您普通的速冻柜就可以批量生产的话,长青认为这真的是一种极度不负责任的回答。为什么普通的速冻柜不能批量使用呢?
第一包子的特性,包子属于发酵食品,从和面那一刻开始包子就处于不断的发酵状态,如果上了两个小时还没有冻透的话,那么它很有可能在冰柜里已经发酵过头了,不能再使用。
第二, 包子馅儿里面含有水分,如果长时间没有里外冻透,那么水分就会渗透到包子皮里面,影响包子皮的口感,包子颜色也会发黄,甚至会造成死面团。
第三, 如果速冻设备不能达到速冻的效果,包子进入冻柜之后冻的时间太长,那么对包子的外观也有很大影响。速度太慢,包子皮的外表皮已经冻透了,而内层却还在缓慢的发酵,那么就会导致外表皮被内部撑破而造成包子皮开裂。
包子皮开裂和变黄除去其他工艺的不对,那么速冻柜温度不够,温度不稳定,也是造成开裂和变黄的主要原因。

三、不同需求选择不同设备
那么使用专业的设备就很贵吗?答案是不尽然。长青认为选择什么样的速冻设备,得根据生产的实际情况来定。
1、实验用,如果只是试验做几个包子,那么家用的冰柜也可以,但请一定少做几个,并且每个包子都尽量做小一些,能保证短时间冻透。所以普通的家用冰柜仅限于做少量实验用,真的生产的时候肯定是不行的!当然试验时有超低温的速冻柜或冻库那是最好不过了。
2、 如果您只有一两个店面,那么您就可以选择一个超低温的速冻柜,比如长青店里的零下40度的超低温速冻柜用着也不错。这种超低温的速冻柜采购成本不高,大约4千元左右。
3、 如果您店面比较多,或者要做批发,那么就得做一个小小的零下40以下的冻库。长青这里说只做一个小小的冻库是因为它只拿来速冻而不储存,所以不必造很大,但一定得小而精,功率强大,造价在4万左右。
另外长青需要强调一点的是:不管是哪种速冻设备,最好选择风冷而非直冷,风冷设备能保证速冻设备内部温度均匀且不会造成湿度过高。
四、编后
当然了,造成速冻产品失败的原因方方面面,不止是设备的问题,还要结合整个工艺流程来判断。这篇文章是相对通用的文章,但无论什么工艺,设备都是最后的关键,希望长青的文章对您在速冻生包子的制作过程中有所帮助。
