防止冷库异味产生：入冷库冷藏的食品，必须经过检验，没有变质的方可入库存放。 冷库库房在进货前不得有异味存在。

Prevent cold storage odor: cold food into the cold storage, must be tested, no deterioration can be stored in storage. The cold storage room shall not smell before purchasing.

若有异味，必须经过技术处理，排除异味后方可使用。 平常要加强冷藏设备的维护，严禁倒堆卸货，防止因此砸坏管路，造成制冷剂外泄。冲霜水系统设计是指用水将冷库内蒸发器上的冰霜除去并排放的过程设计。包括以下几方面:

If there is odor, must be subject to technical treatment, excluding odor before use. Usually to strengthen the maintenance of refrigeration equipment, is strictly prohibited. Unloading, prevent pipeline leakage caused by refrigerant so smashed. The design of the defrosting water system refers to the process of removing and discharging the ice on the evaporator in the cold storage by using water. The following aspects are included:

低温冷库水除霜：“水”的控制低温冷库的冲霜水通常采用15～25℃的普通水。而超低温冷库的冲霜水是将水内加入一定量的乙二醇，山东冷库造价这样可以降低水溶液的冰点。

Cold storage water defrosting: "water" control, cold storage cold water is usually 15~25 degrees ordinary water. The frost water of ultra cold storage is to add a certain amount of glycol to water, which can reduce the freezing point of water solution.

低温冷库由于温度较低，因此，其安装及维护的要求也很高，在日常维护中应该注意：

Due to the low temperature, the installation and maintenance requirements of cryogenic storage are very high, so attention should be paid to routine maintenance:

(1)严禁随意开关，调节冷库温度。

(1) forbid to switch freely, adjust the temperature of refrigeratory.

(2)进出冷库应随手将库门关闭，避免冷气外漏，出冷库时应将库内照明类电源关闭。

(2) the import of cold storage should throw off the door, to avoid air leakage, a cold storage should be in lighting power off.

(3)严格控制冷库温度，减少温度波动。正常情况下，库内温度稳定在-100C以下，货物进出库时温波动不得超过30C：营业期间应每2小时检查一次库内温度，并在温度登记卡上做好记录，运行中发生异常(如温度记录连续三次高于-100C等)，应及时与电工人员联系解决。

(3) strictly control the temperature of the cold storage and reduce the temperature fluctuation. Under normal circumstances, the temperature inside is stabilized below -100C, import library temperature wave shall not exceed 30C: should check every 2 hours inside temperature during the operation, and the temperature on the registration card record, abnormal operation (such as temperature records for three times higher than that of -100C, etc.) should be resolved in a timely manner contact with the engineering staff.

(4)冷库周围严禁摆放有污染，有异味物品，每天营业结束，须对冷库周边环境进行清洗、消毒、将库门锁紧。

(4) no pollution or odorous articles are placed around the cold storage. Every day after the business is closed, the surrounding environment of the cold storage should be cleaned, sterilized and the door locked tightly.

(5)每周应对冷库内的积冰和霜进行彻底清理，注意：清理中只能使用干拖把、干抹布、严禁使用水清洗库板，地面。

(5) a week to deal with the cold storage in ice cream and thoroughly clean, clean up the note: can only use dry mop, dry cloth, prohibited the use of water to clean the base plate, the ground.
