Description

A remote control system for fresh-keeping modules based on the Internet of Things

technical field

Background technique

Fresh food includes livestock and poultry meat, eggs, aquatic products, milk and its products, fruits, vegetables, etc., which are rich in nutrients and mainly provide protein, fat, minerals, vitamins, etc. for the human body. Due to the high protein and moisture content of fresh food and strong enzyme metabolism, spoilage and deterioration are easy to occur in the process of storage, transportation and sales. On the one hand, it will cause serious economic losses, and on the other hand, it will also endanger the health of consumers. Fresh food preservation is to prevent food spoilage and prolong its shelf life. It is a processing measure for fresh food to be preserved for a long time.

During the cooling process of fresh food, when the temperature drops to a certain temperature, the moisture in the fresh food starts to freeze and form ice crystals. This temperature is the freezing point or freezing point. Since the water in fresh food generally accounts for 2/3, up to more than 95%, sugar, acid, minerals and colloidal substances are dissolved in the water, so the freezing point is generally between (-0.5～-3.5) ℃. The existing fresh food preservation physical technology simply cools and refrigerates fresh food or freezes it. When the temperature drops to near the freezing point, fresh food will be gradually frozen.

The water molecules in the fresh food can be polarized by using the low-frequency alternating magnetic field, and keep the low-frequency non-heating vibration with the alternation of the electromagnetic field, so that the freezing point of the fresh food can be greatly lowered. The magnetic field needs to be evenly distributed to all corners of the freezer, so that the fresh food placed in it can get the same freshness preservation effect.

The existing technology does not form a complete remote control system for fresh-keeping refrigerators, freezers, cold storage or cold chain vehicles. The existing technology cannot effectively monitor and adjust the freshness in the remote refrigeration device to achieve a better freshness preservation effect. .
