RU27221U1 - DEVICE FOR VISUAL CONTROL OF THE FACT OF FREEZING OR DEFROSTING FOOD IN PACKAGES, PREVIOUSLY FOOD PRODUCTS, WHEN STORING AND TRANSPORTING - Google Patents

Description

The proposed utility model relates to the industry of storage and transportation of products, mainly food products, in particular, to means for controlling the temperature regime of the above technologies.

Currently, due to the wide development of the food storage and delivery service, issues of monitoring the temperature regime of these technologies are becoming especially relevant, and given the growing share of imports in the food supply sector, this problem is becoming doubly relevant.

Temperature control in stationary freezers at the bases / I / or in specially equipped containers / 2 / is carried out by devices operating in the automatic mode and the probability of its violation, in particular, defrosting / freezing / of products in these circumstances is small, although it can also occur in emergency situations.

The probability of temperature violation during storage and transportation of small wholesale batches of food products is much greater, which is explained either by the lack of appropriate equipment or by the negligence of the loan officers carrying out the transportation.

Small wholesale transportation of food products is usually carried out in containers carried by loaders manually. The control at the recipient of food products is carried out by visual osmogrom of products or organoleptically / 3 /, i.e. subjectively.

Objectively, the violation of the temperature regime during transportation and snoring of food products can be judged by conducting a biochemical analysis of the product in the laboratory / 4 /, which is long and expensive, or by using costly portable portable equipment for assessing product quality / 5 /, which is impossible on a mass scale.

Known thermal indicators / 6 / based on synthesized chemical compounds that are placed on a controlled object, with which you can judge the temperature of the object, the color change of the applied composition / pigment.

However, this hermetic indicator composition cannot be used for control purposes, as has the property of reversibility.

the device is a temperature meter 111 .2

However, the disadvantage of this device, as well as the previous one, is also the impossibility of establishing the facts of freezing or thawing an object without constant monitoring of the thermometer

The task that the author posed during the development of the proposed device was the ability to visually control the facts of freezing or thawing products, mainly food, in the process of storage or transportation with simultaneous simplicity and cheap control device.

The aforementioned task is accomplished in a structure comprising a case with a window and a thermal display unit in the form of at least one ampoule with a freezing, dyeing liquid installed with the possibility of contact with an absorbent element located in front of the case window.

In an embodiment, the device is equipped with a fastening assembly to the container, in the form of an unrecoverable adhesive strip, for example, according to the first type of strip of bactericidal adhesive plaster fixed to the body.

New significant features of the device are:

the implementation of the thermal display unit of two components: at least one ampoule with a freezing, coloring liquid and an element for absorbing the coloring liquid;

-installation of an absorbent element with the possibility of contact with the ampoule;

-installation of the absorbent element in the case in front of the window.

In a variant of the device, new significant features are:

- the unit of attachment to the container, in the form of a non-renewable adhesive strip, for example, by the type of strip of a bactericidal adhesive plaster.

- placement of the attachment to the container on the device.

According to the author, the proposed design, solving the task, is simple in design and reliable in operation.

Pre; southern confusion is depicted in FIG. I and FIG. 2, where in FIG. 1 presents a General structural diagram of the device, and figure 2 shows the placement options of the proposed device on the container.

2- transparent window;

3- glass ampoule;

4- freezing, coloring liquid;

5- absorbent element;

6 - adhesive non-renewable strip.

A device for visual control of the fact of freezing or thawing products in containers, mainly food products, for storage and non-transport, is cured in the form of flat air, / limits the diameter of the ampoule /, a rigid box attached to the container with products.

The housing 1 of the device can be made of any flat shape, for example, in the form of a rectangular parallelepiped made of shockproof non-transparent plastic.

On the outside of the casing 1, a transparent window 2 is made, which can be technologically formed by spraying on the casing of transparent plastic.

Inside the housing there is a thermo-display unit in the form of a glass ampoule 3 with a frozen, coloring liquid 4.

The ampoule 3 is installed in the housing 1 so that it is not visible to the observer, for example, inside the absorbent element 5, made of absorbent material such as synthetic wool.

As liquid 3, ordinary water tinted with any dye better than aniline can be used.

The attachment unit of the device to the container is made in the form of a sticky non-renewable strip 6, like a strip of a bactericidal patch, covered with a protective film.

As a glue any universal glue can be used quickly about “grabbing, for example,“ Momeng

As already indicated above, the device is glued by representatives of the manufacturer of products on containers with products of heat-resistant universal glue or using adhesive tape on the device manufacturing option.

Work with the device is as follows.

was not exposed to negative temperatures, then the amnula 3 of the device does not crack and the absorbent element 5 is not stained with liquid 4 and only the color of the unpainted absorbent element 5 is visible in the window 2.

If the fruit container was exposed to low temperatures, then the liquid 4 in the ampoule 3 freezes and splits it and then stains the absorbent element 5, which is visible in the window 2 of the housing 1 as a color indicator.

The product receiver, having seen the absorbed element 5 / color indicator / in the window 2 of the device, can clearly say that the products in this container were exposed to low temperatures.

In the case of products that must be stored and transported frozen, in the device, if there was no defrosting, a color indicator will not appear, because frozen colored liquid 4 is not absorbed by element 5.

If the product is thawed at any storage or transportation stage, the frozen liquid 4 stains the absorbent element 5 and the product receiver will observe a color indicator in the window 2 of the device body 1, which unequivocally establishes the fact of violation of the temperature regime of storage and transportation of frozen products.

Currently, the author is working on the commercial development of the proposed device at one of the enterprises in Moscow.
