Abstract
A device which is used to cool fermentation tanks and which can be used essentially in beer production, cooling and maturation, includes a vertical heat exchanger, which comprises single- or double-wall concentric cylinders and is positioned internally at the center of a tank. The length and capacity of the cylinders differ depending on the size and shape of the tank. A coolant flows through the cylinders in order to cool and to maintain a suitable temperature range. In addition, the double-wall cylinders which form the heat exchanger are interconnected by means of coolant flow and support tubes. Meanwhile, the exchanger is supported by the cone and the walls of the tank by means of tubes which are used for the passage of the coolant and the passage of signals. Moreover, the outer wall and the cone can be provided with a cooling jacket.

- To the best knowledge of this invention's authors, objectives can be summarized as follows.
- It is a purpose of this invention to have an internal vertical cooling equipment for fermentation tanks, which can use any kind of coolant inside beer fermentation, cooling and maturing tanks. System optimizes temperature control and distribution inside the tank during fermentation, resulting in a better quality beer, in addition to significantly shortening cooling time as compared to conventional systems.
- This invention has also the purpose of being versatile equipment such as to be compatible with traditional equipment featuring external cooling jackets, so it may be used jointly with said equipment as an upgraded feature, or may be used in new fermentation tanks.
- Another objective of this invention is to have a vertical heat exchanger, immersed in wort or beer inside fermentation tanks, consisting of double-metallic-wall pipes or cylinders, through which coolant will pass without getting mixed with beer wort. The heat exchanger, as it is located inside fermentation device, achieves temperature homogenization, thus optimizing cooling and fermentation process, preventing high liquid temperature differences which result from exothermal fermentation in the various liquid areas, consequently achieving a better quality beer as a controlled fermentation is attained, and at the same time, minimizing undesired heavy, volatile alcohols and sub-products formation.
- This invention has also the purpose of counting on a heat exchanger which can be manufactured in any size and proper capacity according to cooling requirements, i.e., volume to be fermented and cooled. The heat exchanger arrangement inside the tank can be anyone and it can be manually or automatically operated or a combination of both. Dimensions or diameter of fermentation tank to be cooled does not involve limitations. In addition to, an extensive heat exchanger has been developed, as to be able to use concentric systems combinations having several geometry, unlike having fermentation tank external jackets as the sole cooling element as occurs in conventional fermentation tanks.
- As another characteristic of this invention, it has been foreseen to remove cooling jacket installed in conic bottom of conventional fermentation tanks, due to feasibility of locating vertical heat exchanger internally, locating it close to the bottom to cause thermal movement needed to cool that portion of the fermenter, thus achieving the same temperature and fermentation control for the whole tank, and optimizing fermentation process in this way, since in such case double fermentation is avoided.
- As another goal of this invention, heat exchanger geometry versatility has been foreseen by way of simple straight or concentric pipes for coolant passing and its use will depend on application and size of fermentation device. In this case, both coolant supply and extraction of heat exchanger is done from outside the fermentation tank through pipes connected to heat transference units, coolant does not have direct contact with beer wort.
- Another purpose of this invention is to include high pressure and high flow turbine cleaners and spray ball installation, duly oriented for fast cleaning of fermentation tank and vertical cylindrical heat exchanger, making equipment cleaning easy before starting another production batch.
- This invention is also aimed to reduce coolant travel distance inside vertical heat exchanger, therefore temperature difference between coolant and liquid to be cooled is kept high, allowing for better cooling efficiency, unlike external jackets located in conventional tanks, where travel coolant distances are higher, thus having a lower temperature difference average.
- In the case of this proposed invention, by using vertical heat exchanger, coolant circulation speed is increased due to straight geometry of cylinders, through which cooling process is optimized. Likewise, vertical heat exchanger installation in the center of tank decreases different temperature layers formation as compared to conventional systems, and at the same time thermal downstream and upstream natural speed is increased, resulting in minimum temperature differences (more controlled fermentation) and consequently resulting in better products.
- Another objective of this invention is to cause wort strong movement during fermentation, which induces better contact between yeast cells and wort, thus improving the fermentation process. While having a more uniform temperature in wort layers during fermentation, undesired heavy, volatile alcohol and sub-products formation control is improved.
- Another purpose of this invention is to allow for better energy exploitation and less consume since all of its surface is in contact with liquid to be cooled, unlike traditional systems in which jackets outer wall is oriented towards external environment causing environment heat losses, even if isolation is used.
- This invention is also aimed to ease temperature homogeneity and liquid movement during cooling, assisting transmission coefficient improvement and, at the same time, avoiding the need to use carbon dioxide bubbling systems used in traditional systems.
- In wort fermentation tanks for production of all kinds of beer, as well as universal tanks known in the industry as unitanks, of traditional design, temperature control during fermentation, cooling and maturation is carried out through cooling jackets outside the tanks, located on their walls, where only inner side of jacket is used for wort and beer cooling.
- Several jacket designs are used, in arrangements where they are installed in the vertical walls of fermentation tanks and cones, jackets can be installed in vertical or horizontal position, in one or several cooling sections but all of them are installed by welding them to external wall of fermentation tank body.
- In traditional design fermentation tanks, as capacity is increased, so increases their diameter, therefore when jackets are installed outside, cooling zone distance to center of the fermenter is increased reaching distances higher than five meters, causing temperature control not being uniform and inadequate liquid movement, thus promoting layers formation and temperature differences which sometimes are higher than 3° C., preventing a controlled fermentation, causing undesired sub-products formation. This is quality detrimental for beer produced. The aforementioned situation becomes more evident as fermentation tanks capacity is increased. This forces some beer producers to limit fermentation tanks size in order to decrease such effect, which involves increasing investment costs, as more fermentation tanks have to be acquired and consequently increasing beer production costs.
- Likewise, using external cooling jackets limits tank geometry design, since in order to account for a higher heat transmission area from external cooling jackets and higher cooling speed, a straight section height/tank diameter high ratio, higher than 2:1 is required, which is against technological requirements for quality beer production.
- In conventional systems, it is required to locate cooling jackets in tanks conic bottom in order to control fermentation and cooling in this area, having an independent temperature control. These jackets do not always operate similarly to upper jackets, resulting in two types of fermentation, which is detrimental for quality of beer.
- On the other hand, beer cooling speed at process final stage is limited by available jacket areas, therefore having longer fermentation tanks occupation time, thus requiring a larger number of them in order to achieve desired breweries production capacity.
- Heat transmission coefficients in conventional design featuring external cooling jackets are generally low, this factor, as well as the fact of using only one side of jacket for cooling, involves limitation of its efficiency. It is common to use carbon dioxide injection at final cooling stages, in order to accelerate beer movement and thus increase heat transmission coefficient for a faster cooling. Additionally, at outer jacket side, even when it is isolated, there is an energy loss by heat transmission due to the high temperature difference between external environment and coolant temperature.
- Summarizing, traditional systems tend to difficult beer quality control and to induce long cooling periods, which increase production costs.
- This invention, consisting of a heat exchanger located internally, vertically positioned, corrects and upgrades traditional systems performance.

- As referring to said figures and following same nomenclature of reference signs shown, this invention consists of an internal
vertical heat exchanger 30, to be installed inside atank 10, three main sections are underlined from the latter: an upper,dome cap 12, whose function will be to maintain sufficient space as to store gases formed during fermentation process; acylindrical body 14, whose function will be to contain beer wort to carry out fermentation process, whose exothermal reaction requires cooling and also to cool the beer after fermentation, to do so acooling jacket 20 may be fitted on external wall, the whole fermentation tank is usually isolated in order to decrease heat losses toward environment and, the conic-shaped bottom 16, with variable design angle, whose function will be to receive and store deposited particles, which are finally extracted by alower valve 18, same as wort and beer after separating deposits. - Inside
fermentation tank 10, aheat exchanger 30 is located, centered and vertically positioned, whose function will be to cool wort and beer and to maintain them within the desired temperature range during the various process stages. - This
heat exchanger 30, comprises a set of two straight concentric cylinders forming a double-wall by which a coolant will pass, to maintain beer wort and beer within desired temperature ranges; which form theexternal cylinder 32, they are attached at each end to some doughnut-shaped coolant distributors, which we call, upperexternal collector 40 and lowerexternal collector 42, through which coolant will be supplied, distributed and evacuated. - Similarly, there is another set of two double-wall, concentric straight cylinders, vertically positioned and concentric to
external cylinder 32 forminginternal cylinder 34, they are attached at each end to some coolant distributors, also doughnut-shaped, which are called upperinternal collector 44 and lowerinternal collector 46, and through which a coolant will also pass. Theseexternal collectors internal collectors - Both external and internal collectors are arranged in combination with concentric cylinders forming a double wall closed at the ends, carrying
multiple holes 48, for coolant distribution and extraction, located in periphery of said ends and confined by a hemispherical, doughnut-shapedcover - Double-wall
external cylinder 32 ofheat exchanger 30 is connected at its lower end to lowerexternal collector 42, and has piping installed on it 58, whose function will be both to supportheat exchangers weight conic section 16 side walls. On the other hand, piping 50 and 52, have the function of supportingheat exchanger weight 34 and additionally to serve as coolant conduction ofexchanger 32 to 34. Coolant conduction ofexchanger 32 to 34 can also be carried out throughpassage 56 at the lower side, and evacuation at the upper side ofpassage 50. In addition, at the upperexternal collector section 40, there is support piping 60, also equidistantly distributed, which is attached at its ends tobody wall 14, which in addition to maintainingheat exchanger 30 positioned, will serve for coolant exhaustion, and temperature sensors signals conduction. At least three lower support piping 52 and 58, as well asupper ones - Through one or various 58 piping, or through piping 74, coolant will pass to lower
external collector 42, to go throughjacket 32 and from there to upperexternal collector 40, from there it will be transferred throughpassages 60 to outside fermentation tank. Similarly, throughpassages internal collector 46, to go throughjacket 34 and from there to upperinternal collector 44, from there through any of thepassages 60, to evacuate coolant outside fermentation tank for collection. - Through proposed
heat exchanger 30, atconic section 16, a stronger wort internal stream is produced, coming from concentric space formed by sets ofjackets FIG. 2 ), making installation of anexternal jacket 72 on externalconic wall 16 unnecessary unlike conventional systems, since cylinders distance to the bottom can be additionally adjusted. Such movement is desired in order for most of wort to be in contact with yeast and for biological reaction to be carried out more easily to obtain beer. The above mentioned effect also applies at cooling stage, avoiding the need for carbon dioxide bubbling in traditional system, which is used to increase transmission coefficient. - Oil purging, in case of using ammonia as coolant, is external to the tank, and any of support piping 58 is used for drainage. Equipment has also been fitted with air purge lines 24, whose function will be to expel air accumulated inside
heat exchanger 30 collectors, in case of using glycol as coolant. - Cleaning requirements are very important to prevent undesired biological infections, this is achieved first: by manufacturing exchange systems attaining a high polish degree at exchanger surface and its parts, in order for yeast, waste, foam, beer detachment to be fast when using detergent solutions.
Heat exchanger 30 mechanic design is such that during cleaning, its whole surface is in contact with cleaning liquids. A distribution system for cleaning solutions consists of a high pressure and high flow cleaningcentral turbine 22, and at least four auxiliaries, one of them at the lower side ofexchanger 30; which cleansfermentation tank 10 internal walls, as well asheat exchanger 30 surfaces, achieving an efficient cleaning on the basis of flow, collision strength on walls, cleaning concentrations and cycles, as well as flow pattern, in addition to being a dismountable system for inspection and maintenance purposes, as well as integrating sensors detecting flow movements in turbines to ensure cleaning, saidturbines 22 have been selected for self-cleaning between each other to ensure a wide spectrum cleaning. - On the other hand,
temperature sensors 66 can be installed inside fermentation tank in any position in supply orevacuation pipes - As a modality of this invention,
heat exchanger 30, may consist of a higher multiple of jackets as it is shown inFIG. 8 , or of a jacket cluster as shown inFIGS. 9 and 10 , being possible to attach these jackets as they are shown inFIG. 14 . - The usage of
distribution fins 60, has also been foreseen, they consist of deflector plates to ensure a closer contact and heat exchange as it is shown inFIGS. 16 and 17 , or radialintermediate jackets 68 between jackets ofpipes - Finally, depending on fermentation type desired to perform,
heat exchanger 30, may have different dimensions forexternal jackets 32 andinternal jackets 34 length as it is shown inFIGS. 20 a 26. - That means this invention is versatile enough as to be adapted to any liquid fermentation process, and to several fermentation tanks capacity and geometry, even for upgrading existent conventional fermentation tanks, regardless they may have external jackets already installed.
- Coolant fluid can be of any type, that means, it can be a liquid with a high evaporation index, or else, a liquid not experiencing an important physical state change or liquid with solids with or without state change.
- Coolant supply can be carried out indistinctly at the
upper side 60, or at thelower side heat exchanger 30. - For example, for the case of ammonia, or any liquid-gas coolant, supply may be carried out at the lower side or at the upper side, while if they are liquid systems such as glycols, supply must be carried out through lower side.
- Whatever supply is used, exhaustion will always be the opposite, that is, if the first is done through the upper side, the latter should be done through the lower side and vice versa. This will depend on the type of coolant used, however, regardless which coolant is used, system is not altered. Decision as to which one to use is the user's choice.
- When
fermentation tank 10 is filled with wort to be fermented, coolant entersheat exchanger 30 for example, by the lower side throughsupport pipes 58, or throughside connections 74, supply may be done through one or all pipes, depending on fermentation tank size and process used, flow being controlled by valves externally located at coolant supply inlet. Information signals for temperature controls are made throughsensors 66, which in the case of this invention, can be installed inside the tank in order to achieve more accurate fermentation readings and controls, unlike conventional systems, in which sensors are installed at fermentation tank wall. - Once coolant enters to
distributors concentric jackets upper collectors pipes 60 also used asheat exchanger 30 support to maintain it positioned inside the tank. Liquid-gas type coolant, for example ammonia, can also be supplied through upper side, flow is inverted, and the only change is type of distributors to be used. - In case of using a liquid coolant, for example glycol, supply is made through
lower side external collectors air purging system 24 is installed inupper collectors - On the wort and beer side, downstream and upstream as well as circular stream will occur, as shown in
FIG. 2 , due to wort or beer density and viscosity changes. These changes in liquid circulation are different to those produced when it is cooled only by tank walls. In the new system, higher turbulence is experienced due to internalvertical heat exchanger 30 distribution insidefermentation tank 10, allowing for a larger portion of wort or beer to be in contact with cooling surface inducing in this way a larger fermentation temperature homogenization, therefore producing less beer fermented at different temperatures and consequently a better quality control. - Exhaustion of coolant used by
heat exchanger 30 is made throughupper collectors fermentation tank 10 by one ormore pipes - For the case involving usage of glycol or dynamic ice as coolant, control system is also similar to conventional ones, using fast close on-off valves for supply control and coolant exhaustion as well as calibrated safety valves and internal venting for purging 24 which are directed and operated from the
dome 12, and where installed are control andvacuum valves 26.
