For

AUTOMATED PANI-PURI(WATER-HOLLOW BREAD) VENDING MACHINE Field of Invention

The present disclosure is from the field of food industry that is related to vending of popular street snack 'Pani-Puri'/'Water ball' of Indian origin. The present disclosure aims to dispense 'Pani-Puri' via an automated vending machine. Prior & Related Art

Pani-Puri ( panTpGn ) is a common street snack in several regions of the Indian

subcontinent. Pani-Puri ( panTpGn ) is a word in Hindi Language. It comprises of a spherical/elliptical, fried crisp, hollow bread and is filled with a mixture of flavored water and other spices like tamarind sauce, boiled potato, chopped onion, boiled white peas etc. The hollow bread could be made of wheat flour, semolina etc.

Pani-Puri literally means "water bread". Pani-Puri has various names, depending on the region. In some parts of Indian states like Punjab, Haryana, Jharkhand, and in other regions, it is called 'Gol Gappa'; in Rajasthan and Uttar Pradesh, 'Pani-Puri'; in West Bengal and Bihar, 'Puchka'; in Sylhet, 'Pakodi'; in parts of Odisha, South Jharkhand, Chhatisgarh, Hyderabad, and Telangana, 'Gup Chup'; and in Madhya Pradesh, 'Phulki' and many more name as per the locale.

Usually the street vendors separately store spherical hollow bread (the round, hollow bread which is fried crisp), flavored water, sauces and other fillings (boiled potato, white peas, sprouts, chopped onion etc.). At time of serving the vendor would take up a spherical hollow bread, would make a hole with thumb/finger, would fill flavored water in spherical hollow bread and supplement same with sauce and fillings as per customers preferences.

The whole procedure is manual and needs to be done just before serving as the hollow bread soaked in flavored water would loose crispiness and would also start leaking. Customers hold a small plate or bowl and stand around the vendor's cart. The vendor then starts making one Pani-Puri at a time and gives one to each individual. Pani-Puri vendors have to remember each customer's preferences such as sweetened water, more filling or extra onions. The vendor must keep count of how many Pani-Puris each person has had.

Though Pani-Puri is famous as street food, it is served in many restaurants and premium food outlets. The procedure to serve is same as mentioned above, while at few outlets, the hollow bread is served in a plate with a cup/glass of flavored water and other spices wherein customers themselves would make a hole with thumb/finger/spoon, would fill flavored water in spherical hollow bread and supplement same with sauce and fillings as per their preferences. Traditionally, Pani-Puris are eaten by placing the entire Pani-Puri into the mouth in one go and biting into it. This releases a barrage of tastes and textures.

Few companies have been selling packaged Pani-Puri wherein the hollow bread is packed separately and paste/powder is included which needs to be prepared as flavored water, by customers themselves.

Pani-Puri is popular in all segments but hygiene and water quality have always been concern as most of the street vendors usually use unfiltered water and serve with bare unclean hands. While few of the vendors have started using hand gloves and other methods but still the overall hygiene is matter of concern.

There have been many vending machine already in operations which could vend items like snacks, beverages, alcohol, cigarettes, condoms etc. There are also specialized food vending machine, which could cook/microwave food items like pizza and other snacks.

Existing vending machines which are designed to dispense fix sized articles, cannot dispense the Pani-Puri, due to following reasons:

1 . Pani-Puri cannot be prepared and loaded in storage for dispensing, as the hollow bread filled with flavored water would lose it's crispiness and start leaking

2. All the components of Pani-Puri like hollow crisp bread, flavored water, sauces , fillings etc. need to be stored separately 3. Automated system for preparation of Pani-Puri would need specialized automation to hold a hollow bread, make a hole and fill same with desired flavor of water, sauces, spices and fillings.

4. The automated dispensing/serving system would need to

dispense/serve a Pani-Puri one by one to a customer. In order to manage crowd, vending machine would need to dispense/serve multiple customers in parallel

5. The dispensing system has to be in sync with the speed at which the customer can eat Pani-Puri

Following are the publications in context to Pani-Puri dispensing/making machine:

1 . Application number 201631001687. In this published disclosure

inventor has given an embodiment which could smash a boiled potato and add spices/flavor to it. The smashed potato is filled inside the puri and dispensed. The flavored water is dispensed separately in different plate and there is no mechanism/system/method for same. The disclosure does not include the transaction mechanism and buyer interface unit. The disclosure can be used only if a human resource is present to operate and take dispensed puri and server water separately. The embodiment also needs prepared flavored water and cannot handle any other stuffing like boiled grams, diced onion etc. The drawings are not clear in the disclosure and not much could be interpreted from the given disclosure.

2. Application number 3500/MUM/201 1 . In this published disclosure the inventor has disclosed an embodiment but the given disclosure will fail as the processed puri with filling and filled with water is supposed to slide out of inclined part #36. As the puri is spherical/elliptical there is no mechanism disclosed how the puri would be served without toppling. Secondly the disclosure does not give a successful mechanism on how the puri from storage unit could be dispense out one by one to the processing plate. The described mechanism of screw 5 is not depicted in the disclosed drawing. The disclosure does not include the transaction mechanism and buyer interface unit. Even if somehow the above defects are managed, the system can be used only if a human resource is present to operate.

3. Application Number 201721012744. In this published disclosure, the drawing depicts a column where single puri could be stacked one over other. Such mechanism may not be suitable for commercial purpose as the length of stack and storage capacity is not viable. The inventor disclosed mere idea/concept how the system could be built. The drawing and details are not sufficient to understand how the puri feeding system, piercing system, water dispensing unit, stuffing unit etc. would work.

To overcome the said drawbacks the present disclosure aims at providing the Pani-Puri via the specialized automated vending machine.

The automated Pani-Puri vending machine would ensure utmost hygiene and quality water from water purifier, it will also reduce the cost of human resource and would provide 24/7 service to the consumers.

Summary of Invention An aspect of present disclosure provides an automated vending machine, specially designed for preparing and dispensing Pani-Puri wherein a buyer can choose desired quantity, one or more type of hollow bread, one or more flavors of water, one or more sauce and one or more filling. After the successful payment by the buyer over the preferred mode(cash/cashless), the vending machine would prepare and serve a Pani-Puri one by one to the buyer. Vending machine would have one or more dispensing counter to serve multiple buyers at a time. Vending machine would have individual storage area for various type of hollow breads, various flavors of water, sauces, spices and fillings which could be replenished manually as and when required.

Pani-Puri Vending machine would have an option to cool flavored water and heat any of the fillings as per buyer's preference.
