  • the present invention relates to cooling systems for rapid cooling of beverages in a container (especially in a cylindrical container) such as fruit juice, milk, water etc.
  • beverages in a container are cooled down by disposing the container in an inner volume (for example on a shelf) of the cooling device.
  • an inner volume for example on a shelf
  • the container loses its heat followed by the cooling of the beverage layer-by-layer towards the center of the container.
  • said layered-cooling towards the center may take a very long time, and if it is desired to drink a beverage in a short period of time, then it may be drunk without being cooled down adequately.
  • the cooling system according to the present invention which is suitable for use in a cooling device and which allows rapid cooling of beverages in a container, comprises at least one machine compartment wherein at least one motor is positioned; at least one cooling compartment comprising at least one chamber in which the container to be cooled down is placed, which is suitable for introducing water and ice therein for cooling the container and which has at least one rear wall, at least one bottom and at least one front wall positioned opposite to the rear wall; at least one main shaft positioned in the chamber such that at least one side thereof is connected to the motor, wherein the container containing the beverage to be cooled down is positioned in the chamber such that it contacts thereto, and which rotates about its axis with the movement of the motor, during the cooling process, thereby rotating the container that is in contact with it; at least one main pool which is positioned in the machine compartment, and in which excess water is collected so as to prevent it from causing damage by overflowing from the chamber to the area where the cooling system is located when the water available in the chamber is above a safe amount of
  • the temperature of the beverage is able to be reduced in a very short period of time (for example, to 5°C in about 10 minutes) though depending on the type and amount of the beverage and/or the size of the container.
  • An object of the present invention is to provide a cooling system for rapid cooling of a beverage in a container, which is suitable for use in cooling devices.
  • Another object of the present invention is to provide a cooling system where the coolant therein can be discharged, if it is in excess amount.
  • Another object of the present invention is to provide a cooling system wherein the efficiency of the cooling is increased by the rotation of the container.
  • Another object of the present invention is to provide a cooling system which is able to be used outside of the cooling device.
  • Still a further object of the present invention is to provide a cooling system which is easy-to-use, durable and reliable.

  • Beverages in containers wherein a liquid such as a beverage is located are generally cooled by being placed in a cooling device.
  • such cooling process is achieved by breaking heat layers towards the center of the container, which takes a relatively long period of time.
  • a beverage having a temperature of 32°C is cooled down in a cooling device, the temperature of the beverage is reduced to 5°C in 5-6 hours on average. Therefore, various applications are needed to reduce the temperature of the liquid in a container in a shorter period of time.
  • various applications are available in the prior art directed to said rapid cooling process, these applications cannot ensure sufficient efficiency and cannot fully meet the needs of the users. Therefore, with the present invention, there is provided a cooling system wherein the disadvantages of the prior art applications are eliminated and the cooling efficiency is increased.

  • the inventive cooling system (S) comprises at least one machine compartment (2) wherein at least one motor (2a) is positioned (which is preferably fixed at least at two points by means of a shock-prevention member such as a felt, rubber etc.
  • At least one cooling compartment (1) comprising at least one chamber (1a), in which the container (E) to be cooled down is placed preferably in horizontal direction, which is suitable for introducing water and ice therein for cooling the container (E), and which has at least one rear wall (5a) preferably facing the machine compartment (2), at least one bottom (6) and at least one front wall (5b) positioned opposite to the rear wall (5a), and the cooling compartment (1) being preferably engaged to and disengaged from the cooling device (C) by means of at least one sliding mechanism such as a slide, rail etc.

  • the cooling system (S) also comprises at least one main pool (2c) positioned in the machine compartment (2), wherein if the water available in the chamber (1a) during the cooling process is in excess amount, the excess water is collected in order to prevent it from flowing from the chamber (1 a) and causing damage to the area it is located (for example inside of the cooling device (C)) (said main pool (2c) also ensures that the noise of the water is reduced during the discharge of the water from cooling compartment (1) and it is not heard from the outside); at least one drain (2f) positioned in the main pool (2c) such that it is preferably located on at least one pool base (2e), and having at least two apertures at least one of which is opened to the main pool (2c); at least one main transfer line (B1), at least one side of which is connected to the other aperture of the drain (2f), wherein the excess water received from the chamber (1a) into the main pool (2c) is passed therethrough, preferably through the pool base (2e) inclined towards the drain (2f), and removed from the main pool (2c
  • said cooling system (S) preferably comprises at least one cover (F) suitable for closing said chamber (1a) (which cover (F) may either be a piece such as a shelf provided in the cooling device (C) or may be an external piece). If the water in the chamber (1a) exceeds a certain amount after the container (E) containing the beverage to be cooled down is placed into the chamber (1a), it lifts the said container (E) and prevents contact of the container (E) with the main shaft (1b), in which case the container (E) cannot rotate and the cooling process cannot be performed in an efficient manner. Furthermore, in case there is an excess amount of water, the water in the chamber (1 a) overflows. Said safe amount of water is defined as a level where the water in the chamber (1a) is prevented from lifting the container (E), and the water in the chamber (1a) is also prevented from overflowing to an environment where the chamber (1 a) is situated.

In this way, heat exchange of the container (E) with a mixture of water and ice is accelerated, and instead of reaching to the center of the container (E) gradually and layer-by-layer, heat is allowed to reach thereto in a direct manner by breaking said layers, so that the beverage in the container (E) is cooled rapidly.
