冷庫安裝中制冷設備也要進行水平固定并且保證不會發生晃動。冷庫制冷設備要在相互互不影響的情況下盡量靠近,因為制冷設備距離太遠的話,就會浪費相互連接的管道,對對制冷劑的流動不利。
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.
低溫保鮮是人們普遍采用的技術措施,冷藏是肉品保存在略高于其冰點的溫度,通常在2~4 ℃之間,這一范圍內大部分致病菌停止繁殖,便嗜冷腐敗菌仍可生長。
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.
干燥處理及添加食鹽和糖是最常見的低水分活性保鮮方法
Drying and adding salt and sugar are the most common low moisture active preservation methods.
(1)高溫能殺死肉類的腐敗菌和致死菌,抑制能引起腐敗的酶活性
(1) high temperature can kill spoilage bacteria and lethal bacteria of meat and inhibit the activity of spoilage enzymes.
(2)熱處理肉制品必須配合其他保藏方法使用。
(2) heat treated meat products must cooperate with other preservation methods.
(3)加熱不能防止油脂和肌紅蛋白的氧化,反而有促進作用;
(3) heating can not prevent the oxidation of lipid and myoglobin, but promote it.
冷庫安裝中冷庫庫體是要按照一定的順序進行安裝的:要先對冷庫底板進行安裝,然后依次是側墻站板、后墻站板、以及前墻站板,最后是冷庫頂板,之間存在的縫隙要用密封膠進行良好密封。冷庫安裝中,冷庫庫體要水平固定在地面上,庫體不歪斜才算好。
The cold storeroom is installed in a certain order in the installation of cold storage in a certain order: to install the floor of the cold storage first, then the side wall station board, the rear wall station board, and the front wall station board, and finally the roof of the cold storage. The gap between the cold storage is sealed well with the sealant. In the cold storage installation, the refrigeratory storehouse must be fixed horizontally on the ground, and the warehouse body is not skewed.
