2018-04-04 17:34:44

冷库安装中制冷设备也要进行水平固定并且保证不会发生晃动。冷库制冷设备要在相互互不影响的情况下尽量靠近,因为制冷设备距离太远的话,就会浪费相互连接的管道,对对制冷剂的流动不利。

In the cold storage installation, the refrigeration equipment must also be fixed horizontally and ensure that there will be no shaking. Refrigerating equipment should be as close as possible to each other without affecting each other, because the refrigeration equipment is too far away to waste interconnected pipes, which is unfavorable to the flow of refrigerants.

低温保鲜是人们普遍采用的技术措施,冷藏是肉品保存在略高于其冰点的温度,通常在2~4 ℃之间,这一范围内大部分致病菌停止繁殖,便嗜冷腐败菌仍可生长。

Cryogenic preservation is a technical measure commonly used by people. Cold storage is the temperature of the meat stored at a slightly higher than its freezing point, usually at 2~4 degrees C, most of the pathogenic bacteria stop breeding in this range, and the cold spoilage bacteria can still grow.

干燥处理及添加食盐和糖是最常见的低水分活性保鲜方法

食品冷库

Drying and adding salt and sugar are the most common low moisture active preservation methods.

(1)高温能杀死肉类的腐败菌和致死菌,抑制能引起腐败的酶活性

(1) high temperature can kill spoilage bacteria and lethal bacteria of meat and inhibit the activity of spoilage enzymes.

(2)热处理肉制品必须配合其他保藏方法使用。
