Refrigerated storage is an important way to store food that needs to be kept cool in order to avoid spoilage. This is especially true for perishable items like meat, fish, and dairy products.
Refrigeration isn’t just about keeping foods fresh and safe – it also helps maintain quality, flavor, and nutrients. It also reduces bacterial growth, which can cause foodborne illness.
Cold storage is a crucial part of the food industry and requires a special kind of warehouse management. This includes the handling of fresh produce and other materials that need a cooler environment to prevent spoilage or degradation.
For this reason, cold storage facilities need accurate traceability data kho thuc pham dong lanh. It’s critical to keep track of the location of each product in transit and in a storage rack so that any errors or lapses are quickly identified.
With this in mind, a number of solutions are available for inventory management and tracking. These include last-in, first-out (FIFO) systems, block stacking, rack storage, and point-of-use storage.
FIFO inventory management is essential for food processing and quick-serve restaurants, as it helps ensure the quality of each item in the line and upholds customer expectations. Strict labeling protocol is vital for upholding FIFO, as employees must know when a product was received and its expiration date to determine whether it should be included in the reordering process.
A wide range of technology is used to automatically track temperatures, trigger alarms, and identify potential lapses. Modern software allows team members to scan pallets on delivery, without having to scan each carton and SKU, so they can record temperature changes as they happen. This allows workers to accurately track temperature in a way that saves time and money while still providing reliable records that can be accessed by everyone involved in the supply chain.
A lot of pests are drawn to food, so it is important to make sure that all stored foods are sanitized. The best way to prevent pests from getting into your refrigerated food is to store it in sealed containers.
Besides sealing your food, another important thing you can do to prevent pests is to seal up any cracks and holes in the refrigerator. These are just additional points of entry for pests and can be the source of any food contamination that may happen.
It is also a good idea to keep your kitchen clean and tidy. Keeping your kitchen free of clutter and debris will help to reduce the likelihood of pests entering your home.
You should also keep your kitchen well ventilated and clean, especially when storing raw ingredients such as meats, fish and vegetables. This will ensure that any pests that enter the kitchen will be killed by the airflow and won’t be able to infest your food.
In addition, you should always store your food in properly sized containers and avoid putting dry foods such as cereals, rice and beans in plastic bags or boxes. This is because these can be easily broken into by pests, making them a prime target for pest infestations.
In order to preserve the quality and freshness of cold products, temperature-controlled refrigerated storage facilities must be maintained at all times. This requires a substantial amount of energy to run, and the carbon footprint associated with this process is considerable.
The transportation of cold products can also be a source of significant energy consumption and carbon emissions. This is largely due to the use of refrigerated trucks, and in some cases even freezers.
Moreover, as fresh food demand continues to grow worldwide, cold chains have become increasingly popular. This has increased the number of refrigeration trucks in use, and consequently the amount of energy consumed.
Therefore, reducing the carbon footprint in cold supply chains has become an important issue. To this end, researchers have attempted to develop mathematical models that incorporate environmental issues as part of the operational planning process.
However, a lack of theoretical frameworks has hindered research efforts in this area. Hence, this paper aims to provide a means for addressing the dynamic lot sizing problem of a cold product while accounting for the generated carbon emissions during temperature-controlled storage and transportation activities.
To achieve this goal, two mixed integer programming models are proposed for the case of a total and periodic carbon cap policy. These models are compared using a Lagrangian relaxation approach.
