Description

A temperature indicating device for refrigerated food

technical field

The utility model belongs to the technical field of food processing, in particular to a temperature monitoring device in the circulation process of frozen food.

Background technique

Cold and fresh food is prone to spoilage during circulation, which has an important relationship with temperature changes. The higher the temperature, the greater the temperature fluctuation, and the faster the spoilage rate. At present, all cold fresh and perishable foods rely on cold chains to ensure product quality and reduce spoilage. Food cold chain refers to all links of food circulation from producers to consumers, that is, all links from raw material procurement, production and processing, storage, transportation, distribution, sales to consumers' home refrigerators can maintain a moderately low temperature state. However, the temperature of cold storage, refrigerated transport vehicles, freezers, refrigerators and other equipment involved in the food cold chain is prone to large deviations due to objective and human factors, and it is difficult to predict the shelf life of food. However, there are certain defects in simply judging whether the food quality is up to standard by the production date and shelf life marked on the food packaging by the manufacturer. Therefore, in the food cold chain, the monitoring of temperature is very critical.

Furthermore, the temperature-changing material is water or peanut oil.

The beneficial effects of the utility model are:

The utility model provides a refrigerated food temperature indicating device, which can be pasted in a refrigerated device, and undergoes changes in the surrounding environment such as temperature together with the product, and monitors whether there is a phenomenon of leaving the storage temperature in the entire cold chain. The indicator card is simple in structure, low in cost, safe and reliable, does not cause harm to food quality, can reflect the temperature history of the product in the cold chain, and thus can conveniently and objectively identify the quality and case status of the product.

Detailed ways

The structural features and expected effects of the present invention will be described below through examples, but they are not intended to limit the protection scope of the present invention.

As shown in Figure 1, it is a preferred embodiment of the refrigerated food temperature indicating device provided by the utility model, which specifically includes: a first cavity 1, a second cavity 2 and a connecting pipe 3;

Wherein, the first cavity 1 is a cylinder, the top of the first cavity 1 is open, and the lower part is contracted and connected to one end of the connecting pipe 3, and the contraction is arc-shaped contraction;

The second cavity 2 is in the form of a cylinder, and the upper part is shrunk and connected to the other end of the communication pipe 2;

In another preferred embodiment of the present invention, the first cavity and the second cavity shrink linearly, as shown in FIG. 2 .

The first cavity and the second cavity are provided with a flat portion 4 on the same side, the flat portion of the first cavity and the flat portion of the second cavity are located on the same plane, and an adhesive layer 5 is bonded to the flat portion. The surface of the adhesive layer is covered with a detachable release paper 6 with the same area as the adhesive layer, as shown in Figure 3, the release paper 6 is torn off during use, and the refrigerated food temperature indicating device is pasted on the refrigerated food temperature indicating device. Frozen/refrigerated food refrigerators, refrigerated trucks, refrigerated display cases, refrigerators in the same environment.

The material of the refrigerated food temperature indicating device is PE, OPP, PP, PVC or PET.

A temperature-changing material is arranged in the first cavity, and the temperature-changing material is solid when the temperature is below the freezing point, the diameter of the solid is larger than the diameter of the connecting pipe, and the freezing point of the temperature-changing material is 0-5°C.

The temperature-changing material is water (ice) or peanut oil.

In the preferred embodiment shown in Figure 1, the material is PE, and ice cubes are placed in the first cavity, and the diameter of the ice cubes is larger than that of the connecting pipe, so as to prevent the ice cubes from falling into the second cavity. Tear off the release paper on the flat part and stick it on the refrigerated truck for frozen food. If the ice turns into water in a certain link, it will flow into the second cavity through the connecting pipe. If there is water or ice in the second cavity, it means that the frozen food has been out of the low temperature condition during the circulation process, and timely measures should be taken. Handling measures.

In order to make the ice cube change more significantly, you can add a small amount of water-soluble pigment powder (dry powder) in the second cavity in advance, such as sunset yellow, bright blue or monascus red, etc., if the ice cube melts, water flows into the second cavity In the process, dissolving the pigment is more convenient from the perspective of observation. When there is colored water or ice in the second cavity, it indicates that the frozen food has escaped from the low temperature condition during circulation.

Using water (ice) as a temperature-changing material is suitable for monitoring changes in the ambient temperature of frozen foods (below 0°C).

Another preferred embodiment as shown in Figure 2, the material is PET, solid peanut oil is filled in the first cavity, and the diameter of the solid peanut oil is larger than the diameter of the connecting pipe to prevent the solid peanut oil from falling into the second cavity. Peel off the release paper on the flat part and stick it on the refrigerator for freezing food. The melting point (freezing point) of peanut oil is 4-5°C. If the temperature of peanut oil reaches above the melting point during circulation, it will become liquid and flow into the second cavity through the connecting pipe. If there is peanut oil in the second cavity, It can be judged that the cold and fresh food has been out of the cold and fresh storage conditions (0-4°C) during the circulation process.

In order to facilitate observation, a small amount of water can also be filled into the second cavity, and then solid peanut oil can be filled into the first cavity, and put into cold fresh food refrigerators, refrigerated trucks, refrigerated display cabinets, and refrigerators. When the temperature in the circulation process reaches above the melting point, it will turn into a liquid state and flow into the bottom of the device through the conduit. There will be obvious water and oil stratification under the device. Based on this, it can be judged that the cold fresh food has been separated from the cold fresh food during the circulation process. Storage conditions (0-4°C).

The use of peanut oil as a temperature-changing material is suitable for monitoring changes in the ambient temperature of chilled food (0-4°C).

The utility model has the following advantages:

(1) Judging the temperature change during the circulation of chilled fresh food through the change of the material state in the device.

(2) Through the material color and oil-water layer, the change of material state can be carried out more clearly.

(3) All materials are edible substances, safe and reliable.
