FIELD OF INVENTION The present invention relates to an automated appliance for preparing hot beverage recipes. In particular, the present Invention relates to an automated hot beverage preparation appliance for preparing beverages in a directed manner controlled according to preconfigured or self-determined recipes. More particularly, the present invention relates to an automated hot beverage preparation appliance for smartly preparing personalized beverage recipes in a predetermined quantity and storing therein and/or directly serving therefrom at predetermined temperature. BACKGROUND OF THE INVENTION The invention relates to methods and appliance for preparing hot beverages such as tea, chai, coffee and soup, These beverages are prepared by heating water in a vessel and adding solid ingredients in a recipe driven quantity at the desired time and brewing or cooking them for a determined time. Following an appropriate brew or cook time, the solid ingredients are separated from the. liquid preparation, Tea or chat has milk as an additional ingredient that can be added at any time during the process, depending on the preconfigured recipe and/or user-determined recipe, ranging from being healed with water at the beginning to being added after the brewing or cooking is complete, Tea leaves need to be brewed in water once the water has reached a certain temperature for a given time period. Not adhering to this criterion can result in either a weak or a bitter taste. The recommended specification for tea and coffee are given in the table below: Name of Beverage Brewing Time Temperature (Celsius) With or without: Milk Black Tea 3-5 minutes 95 - 100C with or without Herbal Tea 4-6 minutes 100 C Without Oolong 5-7 minutes 87 - 95 C Without Green 2-3 minutes 71 - 82 C Without Darjeeling 3-4 minutes 90 - 05 C Without Chaf 5-7 minutes 95 -100C with Coffee 3 min 90 - 95 C with or without PRIOR ART Multiple methods of preparing these beverages exist. One method involves the intermixing of solid ingredients (tea leaves, ground coffee, powdered spices) with liquid ingredients (water, milk) for a predetermined duration, such that the flavours tire adequately Put not excessively extracted. Subsequently, the solid residues are separated from the liquid residue or hot beverage prepared. Certain apparatus, such as French press for coffee beans follow a similar process. there is also an apparatus having mechanisms, whereby tea leaves in a sieve are dipped into hot water and subsequently the sieve is raised to avoid further contact Iheiowith. A peculiar element of Chai preparation in India is that the recipes for preparation can vary from household to household, The elements that can vary include the proportion of water and milk in the final beverage, the sequence of adding water, solid ingredients and milk, the liming of supplying heat, the quantity of solid ingredients in every cup, and the temperature to which the concoction is heated. Premix of tea powder and coffee powder which are completely soluble in hot water are used in the conventional hot beverage vending machine. This is an instant method to prepare the beverage, hut not capable of providing the taste comparable to a freshly prepared one, Tea and coffee need to be freshly brewed in a certain way to get the optimal atste, which is not possible in the vending machines using such premixes. This method is also not capable of catering to the individual user preferences in terms of strength and milk percentage of the beverage. Patent publication US 200501270% A for dispensing flavoured hot drinks keeps the flavouring powder and the liquid separately and then they enter a mixing chamber where they are mixed. The limitation comes on account of usage of flavouring powder-instead of the leaf or coffee grounds which impacts the taste, French press involves pouring hot water into a beaker and letting tea loaf or coffee grounds brew in it, The beverage is then separated from the ingredients by pushing a plunger, this is a manual process and the temperature control of the beverage is not possible. The serving temperature of the beverage varies quite a bit since there is no healing mechanism involved. US Patent 5,633,233 is a modification of the French press and includes a beater to help the brewing process. However, the heating is external through a microwave and Ihere is no automation involved in determining the heating and brewing cycles. ihere is a requirement to introduce solid ingredients afresh for each cycle of preparation of beverage. The ingredients once used need to be segregated and disposed before each cycle of brewing. This is bandied by some of the machines by usage of cartridges containing the ingredients which is pierced to extract the ingredients. US Patent 6,655,260 B2 uses a mechanism for usage of cartridges. This puts a limitation on the variety of the ingredients to be used limiting to only those provided in cartridges and also makes it environmentally unfriendly to dispose, Preparalion of some of the beverages require addition of milk to the liquid for preparaton of the beverage, The machines presently handle it by adding heated milk at the end of the preparation cycle but none of them handle the heating of the milk during the preparalion of l.he beverage. This is a requirement especially while preparing chat or milk tea, which the existing machines are not capable of handling, Milk is required for the preparation of some of the beverage. It is required to he stored with the machine and dispensed during beverage preparation. However, this poses a challenge, when milk is kept out of refrigeration for more than T hours, it is likely to get spoilt. Present machines are not capable of handling this situation, the solid ingredients which are dispensed In the liquid are required lo be added in measured proportion for the optimal taste. Addition of more or less tea leaf or coffee grounds will make the brew bitter or weak, Similarly, there are condiments which have to be added in the right proportion. The machines at present either require the ingredients to he measured and added manually or they are in form of premixes to be mixed with the liquid. There is no mechanism to automatically add Ingredients in right proportion. Quality of any hot beverage prepared will be determined by the sequence followed while adding the ingredients, temperature to which they are heated, duration for which I hey are brewed and the proportional quantify in which they are added. Presently, no beverage preparation appliance is available, which is capable of recipe driven control of all these criteria. Moreover, for preparing tea, steeping/soaking is necessary, whereby the tea leaf is left in hot water without supplying heat, this helps in reducing the bitterness of the beverage, None of the present beverage preparation appliances handle this. Patent publication US 2008/274216 At discloses a machine, in which ingredients are put in the infuser chamber by opening il from top and then lowering It into the carafe, for brewing along with the liquid for a predetermined time and subsequently raising the infuser chamber back. A molorised cable is used to lower and raise of infuser chamber, However, the limitation with this machine is that the ingredients and the liquid are dispensed manually. The liquid has to be poured in the carafe and all the ingredients have, to be manually added together, There is no control provided on the amount of ingredients dispensed. Cable lowering is unguided and as such cannot be used to agitate the beverage while brewing. The suggested device will also not be able io handle milk addition and boiling it required tor some of the beverages. There is no control possible on the sequence of addition of ingredients, which are all to be added together and heated. Patent publication US 2010/0018403 At also has a mechanism for raising and towering the infuser chamber with the ingredients into the liquid and also to control the brewing lime. This ts done through a conveyor mechanism infernally built into the carafe which is motoriised. However, this also does not dispense the ingredients automatically and in measured quantity. It cannot handle the milk heating as the same has tendency to spill over at higher temperatures. Therefore, none of the apparatus of the prior art discussed above combines the following features into a single product. Beverage recipes may vary from home to home, it allows the user to experience the beverage with exactly the same taste, thai; they are used to, every time, The following features are key to a user's experience of taste-driven beverage, i.e. the capability of the apparatus to: a) Handle a variety of ingredients to prepare hot beverages including chai, tea, coffee, soup, b) Store ingredients in modular containers and automatically dispense them in desired quantities, c) Complete visibility of the brewing or cooking process, (d) Use the cooking carafe to also serve as the serving carafe, (e) Allow easy cleaning of the storage containers, inf'user chamber and carafe, (f) In one version of the machine, allow the user to be able to prepare their own recipe which allows the user to; a, determine the sequence of addition of solids and liquids, b. determine the quantity of solids to be added in one or multiple dispensing cycles during a single preparation, c determine the quantity of liquids to be added in one or multiple dispensing cycles during a single preparation, d. determine the temperature of the beverage to which it should be heated for one or multiple cycles during a single preparation, e. determine the exposure of solid ingredients to the liquid ingredients for one or multiple cycles during a single preparation f. use milk to be brewed or cooked with other ingredients (and not just to add it to the prepared concoction subsequently), The aforesaid challenges should be properly addressed for developing a hot beverage preparation appliance widely adapted for home and commercial usage, OBJECTS OP THE INVENTION Some of the objects of- the present invention - satisfied by at least one embodiment of the present invention ■• are as follows: An object of the present invention is to provide a hot beverage preparation appliance that is flexible enough to handle both solid and liquid ingredients and to use the same as per the best preparation method recommended thereof, Another object of the present invention is to provide a hot beverage preparation appliance which is capable of customizing the beverage preparation as per individual user's taste and choice.

Figure 8 is a perspective view of the milk container t-02 with the centra! flip strip 8- 01 of the lid 84)2 in a closed position. This milk container 1-02 is located on top of the appliance 1-00. This allows dispensing of milk by gravity. The milk container 1-02 has the upper body 8-03 to store milk and covered by lid 8-02 and the lower body 8-04 houses the milk dispensing mechanism to he explained subsequently. Figure 9 shows the container 1-02 with the flip strip 8-01 in an open position, when it is placed on the appliance 1-10 (Figs, 1-2). This open position of the lid 8-02 allows the entry of air inside but prevents the entry of foreign particles, The milk is discharged through an inclined surface 8-05, directly into the carafe disposed below. Figure 10 is a cross-sectional view of the milk container 1-02 with top lid 8-02 in closed position. A central column 10-01 runs along the length of the upper body for air travel. There is a gap 10-02 between the column and the milk container upper body 8-03 at. the bottom and on the top thereof, column 10-01 is sealed by the central flip strip 8-01 of the lid 8-02 in normal closed position. The flip strip 8-01 lifts, when container 1-02 is placed on the appliance 1-00 for allowing passage of air into the central column 10-01 through the gap on top 11-01 (see Fig. 11). Fig. 10a is an enlarged view of the lower body 8-04 of the milk container 1-02 and includes the solenoid valve assembly 104)7 at the bottom thereof in a closed position, The upper body 8-03 of the container 5-02 has a small hole at the lower body 8-04, which is sealed from below by the gasket 10-05 of the solenoid valve assembly 10-07. The gasket 10-05 seals the upper body 8-03 above, so that milk can be stored therein. The gasket 10-05 prevents the flow of milk in rest condition. Figure 11 is a cross-sectional view of the milk container 1-02 with top lid 8-02 in an open position. On energizing the solenoid 10-07, the ferromagnetic rod 10-06 is pulled down, which in turn pulls the sealing gasket 10-05 down to creates the gap 11-01 between upper body 8-03 and the solenoid assembly 10-07 to allow milk to flow down by gravity through the inclined chute 8-05 (Fig, 8), The air from the lid 8-02 in upper body 8-03 enters through the central column 10-01 (Pig, 10) into the In upper body 8-03 from lower body 8-04, equalising the pressure within the milk container 1-02 chamber to ensure uniform flow of milk. Fig, 11a includes an enlarged view of the solenoid valve assembly 10-07 in an open position. The solenoid valve 10-07 opening time controls the amount of milk dispensed.
