1. Perishable food: Perishable food includes fresh meat, eggs, milk, fruits, aquatic products, vegetables, cold drinks, frozen foods, etc.

2. Basic transportation requirements

Perishable food in different thermal states of refrigeration units should not be transported in the same temperature controlled space of temperature controlled transport vehicles.

Temperature controlled transport vehicles that transport perishable food within the same temperature controlled space are typically limited to the same product name.

If mixed packaging of perishable foods with different product names and properties is allowed, such as when the temperature difference between the upper temperature and the required upper temperature inside the temperature controlled transport vehicle is not greater than 3 ℃, assembly and transportation can be carried out in the same temperature controlled space of the temperature controlled transport vehicle;

Perishable foods with other odors cannot be transported in temperature controlled transport vehicles in the same temperature controlled space as other foods.

3. Strict 3 ℃: During transportation, loading and unloading, transfer, and connection, the temperature change of perishable food itself should not exceed 3 ℃; The temperature of the transport vehicle should be within the transport temperature range, and the deviation between the upper and lower limits of the temperature and the upper and lower limits of the transport temperature should not exceed 3 ° C

4. Application of temperature regulating conveying tools

When the ambient temperature is high, temperature controlled transport vehicles should be used for transportation.

When the transportation time is short and the external environment temperature allows, insulated vehicles (boxes) can be used for transportation, but the temperature change of the goods during transportation does not exceed 3 ℃.

1. When loading, they should be stacked in a good location and manner to allow cold air to circulate between the loaded goods and maintain temperature balance in the cold storage at all times.

It should be noted that items should not be stacked at entrances or exits, nor should they be stacked on the roof of a car.

2. If the refrigerated truck is loaded with green foods such as fruits and vegetables, it should be noted that fruits and vegetables will generate respiratory heat. If the cold air circulation effect of the refrigerated truck is not good, the temperature in the middle of the compartment will rise, directly affecting the quality of the goods.

If the goods are close to the air conditioning vent, the goods on top will be frozen and damaged by the air conditioning. Therefore, after the installation of the box is completed, protective measures need to be taken.

3. The hygiene of the refrigerator requires constant cleaning to ensure that the transported food has good cleanliness. Substances such as fat and salt adhere to doors, interiors, and seals. It is not only unhygienic, but also reduces the corrosion of vehicles.

4. When goods enter and exit, when the cold storage door is opened, external airflow will enter the cold storage, causing the temperature of the cold storage to rise. Therefore, after processing the goods, we should speed up the process.

In addition, if carrying goods, the refrigeration unit needs to be operated directly.

5. Before loading goods, refrigerated trucks should pay attention to pre cooling the transportation equipment and goods in the refrigerated warehouse to ensure the temperature of the loaded goods during transportation. Do not lower or freeze the temperature of the goods during refrigeration

If the temperature of the cold storage unit is high or the temperature of the goods during loading is high, it is difficult to lower its temperature to a more suitable temperature. Therefore, before loading, it is necessary to pre cool the cold storage and goods to achieve a more suitable transportation temperature.
