Abusive model registration Freeze controller

It is known that frozen foods camouflage after being on. may not be frozen again, because this will affect the quality and taste and most of the goods will be unusable at all · Highly frozen foods can be harmful to health especially for ready meals, fish, meat and ice cream »

A frozen food or a packaging of this food cannot be seen in any way as to whether the content is already there. was partially or completely thawed and frozen again

But it can happen very often that frozen foods due to poor or improper storage or a defect in the Freezer or a temporary power failure or a « longer transport with strong tempo fluctuations or at least temporarily insufficient cooling or freezing temperatures are heated up or thawed

Especially the temporary thawing or thawing and then repeated Freezing the food is dangerous because it does the consumer Can't somehow recognize at all ^ there is no visible feature that can indicate a critical condition of the goods From industrial production to the end consumer, the goods should be stored continuously at around - 2o degrees G.

This invention has set itself the task of an inexpensive control device to accomplish·

The invention consists of a simple and economical device before which shows a reliable, optical signal when the frozen goods have been heated to temperatures, which not more are permitted «.

The optical signal remains visible when the goods are returned being frozen

de device consists of a * in any form or Shape of frozen "colored liquid" primarily water " which in a completely closed, watertight and at least is partially packaged thermosetting cover.

When the frozen liquid melts, it loses its shape, indicating that the critical melting point has been reached or exceeded.
The quality of various foods is already at risk if water reaches a temperature below the freezing point «Fü? Such substances are known to the liquid, or to the water, additives for lowering the freezing point, such as salt, dryoerin, cane sugar or dandelion, whereby the melting point and thus the dissolving of the original shape of the frozen liquid can be adjusted and on each the desired point can take place below the zero point »

You want frozen liquid in any form in a put in a waterproof »transparent cover. Wills made of plastic sheeting or glass are particularly suitable for this purpose. There is a change or a melting of the shape in the shell the sign "that the critical temperature has been reached" you shape the frozen liquid can also be a logo or a number »a letter or other symbol ·

An absorbent material, preferably absorbent paper, can also be used in the cover » old, which can soak up the melting, colored liquid and thus visibly cut the color of the melted Liquid shows

It is two-dimensional when the frozen liquid is separated from the absorbent Fabric is completely enveloped so that the color change this Substance is a clear visual sign that the critical freezing temperature has been reached

In this version it is unimportant »which shape the has frozen liquid, e.g. small balls, chopsticks, or anything at all can also be used. be small pieces *.

Enveloping the frozen liquid with the absorbent material is delayed Melting too quickly even when the critical temperature is reached; a »whereby a short-term heating of the frozen goods in the L did no harm *

You frozen liquid can also come from cables with different Colors exist »which then, when melted, unite and become one be able to produce a new color

You at least partially transparent cover in which the frozen Liquid »preferably enveloped with an absorbent substance, sticks» prevents the liquid from getting in any way with the frozen food Contact can come *

After in practice at the time of freezing the food not always a frozen liquid in the sense of this? invention can be available »it is also possible to use an embodiment» which as a supplement to this invention is as follows builds up s

You be frozen "colored liquid is poured into a small loading containers" such as a small glass vial or capsule and sealed "that can throw blasted the ampoule or capsule during the freezing of the liquid · You known Volumenvf t gröeserung dee water on reaching the freezing point, inter alia, about 1o # then causes the "bursting of the small container" to burst if the water can no longer find enough space to expand in the container while it is freezing. When the zero point is reached, the water already becomes ice »or begins to become ice and can therefore no longer soak and color the substance» which envelops the ampoule *.

This version of the freeze controller then consists of the one with Liquid-filled ampoule or capsule, which is encased by a suction steff and welded in a transparent cover Plastic film or the like is stuck

It can "be stored anywhere and only begins to function when frozen with the food, in a freezer or like is inserted »

By bursting the ampoule or capsule, the frozen liquid is removed when the melting point is reached again free-liquid and from absorbed by the absorbent, which then makes a clearly visible jräibung is achieved as an optical signal ·. ' Site envelope prevents the liquid, which from the Saugetoff k completely is picked up and still comes into contact with the refrigerated goods somehow

In this version, which can be used for any length of time at normal temperatures remains storable, one is independent of the presence of a frozen liquid! that of a frozen liquid in a special shape »

The embodiment of the controller can ir any desired size, but in particular Weerden kept very small, a small sotfJ controller can also be inserted in Einseipackungen or the like. With without thereby much Fiat to claim ·

Model 1 shows a glass ampoule in which a colored liquid is frozen, represented by red glass beads

Model 2 shows a finished controller in which one with a

Ampoule wrapped in absorbent material in a plastic film cover plugged·
