Description

DESCRIPTION

QUICK COOLING METHOD AND SYSTEM, ESPECIALLY FOR DRINKS

The present invention is subject to a cooling method which provides the wrapped products, that are required to be cooled, to be moved in order in a liquid cooling environment, and each of the particles of the product to be in contact with the - cold environment and thus, it provides the product to be cooled down from the room temperature (25⁰C) to 4-7 ⁰C in a time period of less then seconds, and a cooling system showing the process of such method.

Scope of The Invention and The State of Art :

In respect of thermodynamics laws; the thermal energy of a material always trends to flow from the high temperature zone to the low temperature zone. The transfer of the thermal energy from one zone to other is eventuated by three ways called as conduction, convection, and radiation. Because of the heat amount transferred by radiation is at a negligible level under the temperatures of 600⁰C, the existing cooling techniques, have been improved as based on thermal energy transfers eventuated ^'by conduction and convection. As is known, on the heat transfer eventuated by convect-ion, the cooling gas is flowing in a turbulence way over the product which is to be cooled and is taking the heat of the product. ^" This method is being used rather in industrial applications, because -an additional system and area is needed in order to let the cooling material to provide a flow in a turbulence way .

The known oldest and the mostly preferred method is the heat transfer eventuated by conduction, and at the same time it is forming the basis of the subject invention of cooling method. As is known, the heat transfer eventuated by conduction, is being performed by transferring the thermal energy of the material which is in a colder environment then itself, its particles hit to each other and thus the heat energy is transferred to next one by contacting.

As is needed to explain more detailed; the particles on the outer surface of the material, which are in contact with the cold environment, are cooled down by transferring their heat to- -the outer cold environment. Subsequently, these cooled particles hit to the particles nearby which are warmer then they are, and thus, they are causing these warm particles to be cooled down. In this way; it is provided that the heat of the particles in the centre is transferred to each other by hitting and thus the heat of all particles is transferred to the cold environment .

The point remarked here is this,- when two particles hit each other, they are sharing the total heat in direct proportion of their masses and specific heat values. In respect of this; when it is being taken into consideration that the particles of the material which hit each other have the same masses and specific heat values; when a cooled particle hit. to a warm particle; this cold particle is warmed again in half portion and at the same time, the cooling amount (the heat amount that is transferred) on the particles through to the centre of the material -is being gradually reduced. In this method; a need for a definite time period is being discovered in order to get all particles to the required heat. This time period is about 25-30 minutes due to the volume of the material which is required to be cooled down.

Nowadays, some solutions have been analyzed in order to reduce the time period that is required for cooling a material. The mostly preferred one is to increase the heat amount transferred on hitting of the particles by means of getting the heat values of cooling environment to the rock bottom levels. Although this method in practice got the time 5 period down to about 10-15 minutes; a need for an additional energy is being discovered in order to keep the heat of the cooling environment at low values. All the same; when the cold drink needs of the restaurants, cafes, hotels, and etc in hot regions is taken into consideration, a time period of0 10-15 minutes for cooling is still too long, and is not enough to meet the requirements. Furthermore, it is possible that when a gas at room temperature is placed in an environment with a very low temperature, it should get to solid phase by directly depositioing. 5

The above mentioned time period for cooling is being reduced economically and practically to a very short time period such as seconds by means of the method subject to this invention. To the effect that; the material which is required to be0 cooled down is provided to move regularly in the cooling environment by means of an electrical motor reducer, perpendicular movement shaft (11), gears (12) and horizontal housing box (13) and thus; without waiting all the particles

- - hit to each other, it is provided that these particles are5 transferring their own heats to cold environment in less quantity of hitting, .and by touching directly to particles of the cold environment^'. In this way; all the particles of the material which is required to be cooled down are getting to the required low hea-t in a short time such as seconds.

After this part, the method subject to this invention and the system about this method will be described in more detailed way by referring to the attached drawings . . .. In these drawings :

Detailed Description of The Invention :

The object of the method subject to this invention is about cooling down .the material in a cooling environment and in a short time period such- as seconds. "

Within the scope of this invention; a quick cooling method in order to achieve this object in economical and practical way is compris-ed; and it is also comprised that the material required to be cooled down is provided to be moved regularly in a cooling environment and thus, each of the particles of this material is provided to hit as far as possible to. the particles of the outer surface which are directly in contact with the co.oling environment, and so the material is cooled down.

The outer surface of the material, which will be cooled down, is continuously in touch with the cooling environment. Accordingly, when one of the particles on the outer surface hits the warmer particles inside, it takes their heats and thus, the heat increases continuously. But, at the same time it also hits to the particles of the cooling environment to which it is in contact with, and so the heat it has taken from the particles inside is transferred to the particles of the cooling environment.

By the innovation subject to this invention, the material, which is placed in the cooling environment, moves regularly in a chamber (5), _.where the cooling environment exists, by means of a movement system consisting of an electrical motor reducer, perpendicular movement shaft (11) , gears (12) and horizontally active -housing box (13) . As a result of this movement; all the particles of the material, which will be cooled ^'down, hit to the cold particles on the outer surface as far as possible and thus, these particles are transferring their own thermal energy directly to the particles- on the outer surface which are in contact with the cooling environment. In this way, the amount of the thermal energy which has been lost on one hitting of every single particle increases mainly and thus, each of the particles reach to the required heat values as a result of less amount of hitting.

All the views of- the cooling system related to the above mentioned method are given on Figure 4. As seen on this figure; the cooling system is consisting of two main parts: the upper part where the cooling process is taken place and the bottom part where the cooling group is placed, this group provide the cooling environment to be kept continuously in the same low temperature .

This cooling group is placed into a special insulated housing; it is consisting of a compressor (1) for having the necessary power, a condenser (2) and a coolant fan (3). -These members are connected to each other by means of iunction pipes (4) and an expansion valve. This cooling group, as it is like in the cooling devices of the contemporary state of art, is keeping the cooling environment in a sufficiently low temperature . The upper part is basically consisting of a chamber (5) of cooling environment with a sufficient volume chosen due to the capacity requirement, an evaporator (6) placed inside of this chamber (5) , a perpendicular movement shaft (11) which provides the material to be immersed into the chamber (5) and to be rotated in the. chamber (5) as hand free and an electrical motor reducer.

The liquids having a very low freezing level such as calcium composites, mercury, antifreeze, salty water and alcohol are preferred in order to form a cooling environment in the chamber (5) . Within the scope of this invention, the main reason to use liquid for the cooling environment on the contrary of gas used in the contemporary state of art, the material in liquid phase has closer particles and these particles hi-t to each other more as per time unit, and thus, the heat is transferred more effectively.

The cooling system is placed into a box which is coated by sealant (.7), -arid there is an open window (14) at a specific size on the front surface of this box, from this window the housing box (13) can be seen.

The user is placing the wrapped product, which he wants to cool down, into . the housing (13) when this housing box is aligned with the window -at upper position- as shown in Figure 1 with broken lines, and he is fixing the product in the box by means of a clip existing there. By drawing the slide lever (15) manually down which is placed just on the window (14) , the slide (17) is locked by sliding it do.wn inside the slide groove (16) and thus the window (14) is closed.

By drawing the slide lever (15) down; the slide (17) , the spring (8) connected to the slide (17) by means of a junction member and the perpendicular movement shaft (11) connected to this spring (8) are all moved down, and fixed at a point where the slide (17) is locked by means of a lock switch (22) . At the "same time; the housing box (13) which is connected to the jnovement shaft (11) by means of gears (12) and worm screw (10) moves down, and immerses into the chamber (5) of the cooling environment.

All the same; by means of an electrical motor reducer and a gear set, the bottom part of the perpendicular movement shaft

(11) rotates at a specific angular velocity. Accordingly, it provides the box housing (13), which is connected to itself by means of worm screw (10) and gears (12), to be rotated at the same speed.

In conclusion; the particles of the material, which is required to be cooled down and which is placed into the box housing (13) that is rotating at a specific angular velocity in the cooling environment, are shifting continuously, and each of the particles is directly in contact with the cooling environment and thus, these particles have the chance to hit the outer surface particles which are at the low temperature. In this way, the heat of the particles is dropping down to the required level as a result of fewer hitting, means in a shorter time period. When the hitting quantity per second performed by the particles in a liquid phase under normal condition is taken into consideration, the product is provided to be cooled down in a time period less then one minute . There is a digital indicator (24) on the cooling system, and it is adjusted beforehand by the user due to the mass and the heat of the product, which is required to be cooled down. After the time (as per seconds) is up which is adjusted beforehand, the user will draw the slide lever (15) up again, means that the slide (17) and the housing box -(13) connected to the slide (17) by means of the spring (8) will be drawn ^■ up, and finally the window (14) will be opened in order to serve the cooled product to the user.
