BISCUIT SANDWICH MACHINE

Need Statement

A new food outlet in the town is gaining popularity with their unique dish "Biscuit Sandwich". In order to expand the business across the town with uniformity in quality across all outlets and to provide the service to wide food lovers, the owner wants a automated biscuit sandwich maker which can be installed in all the outlets, Super Market And wants to Attract the Customers.

Introduction

Automation in food manufacturing has been a primary solution in improving the consistency, safety and accessibility of food in major consumer markets. The applications of automated manufacturing process range in scale from the large production lines found in factories to the recent trend of single-serving coffee brewers for office and home settings

Cream sandwich biscuits occupy a significant place in the world biscuit market. The term "cream" implies a non aqueous aerated mixture of sugar and fat

And for now if we are hungry and urgently want some to eat then most of the people prefer cream biscuits of biscuit sandwich

Typically, Biscuit sandwich is basically two identical thin biscuits which contain a layer of sweet or salty cream in-between. There are many variation in this basic type such as the top biscuit/shell might be of different type or the biscuits may have holes in them or it may have 2 different types of cream or the biscuit sandwich is dipped in chocolate

Why Biscuit Sandwich Machine?

We want customers to see how the machine works (which is really cool and interesting to see from a engg student perspective) and want them to serve fresh biscuit sandwich which are straight out of the machine and are healthy, eco-friendly, attractive, and easy to use. So that we can keep it any super market and customers can access from there

Importance/Need Of biscuit Sandwich Machine

• Reduces Manual Work
• Applies Fixed Quantity of Cream in-between to All Biscuit Sandwich
• There is no need of continuously monitoring the machine until there is a alert
• Can apply 2 different types of cream easily
• Can operate anywhere and anytime

1	https://youtu.be/yrUVQ_265RI	In this video, the machine takes biscuits as input, pipes cream on them and then later places another biscuit on top.	Tray, Conveyor belt ,Cream injector, Motor Gears ,Screws, Steel sheet, Switches	Electrical wires,LEDs,Jump wires,Arduino,Sensor	The machine first pushes a biscuit on the belt, then pipes a sufficient amount of cream on the biscuit. The biscuit is then taken to the end of conveyor belt where another biscuit is placed on top
2	https://youtu.be/peT1fBdW2Us	In this video, we can see that biscuit has to be kept on a belt on which the cream is placed. Later, the machine placed a biscuit on top of it	Belt, Pipes for applying cream ,Steel sheet,Screws ,Motor ,Gears	Electrical Wires,Jump wires ,Arduino,Sensors	This machine can take two biscuits at once and apply cream on it with the help of pipes and sensors. Another biscuit is kept on top.
3	https://youtu.be/9eVJWb1ojYc	Program logic control based project which make sandwich of biscuit which has 2 biscuit storage and one cream dispenser	Cream threaded shaft,cream dispenser,biscuit ejector,conveyor,motor(5) , Slider crank mechanism , cam & follower	convertor distribution panel ,convert distributor ,wires ,mother board	the biscuit roll on the Cream threaded shaft and roll automatically later the biscuit is placed with one another by cream through cream dispenser through the help of slider crank mechanism
4	https://youtu.be/m1YpcVQoPB	Biscuit rolls over the machine after the instructions are been given to it by the screen input and applies cream using pressurized cream dispenser	Conveyor belt, pressurized cream dispenser, cam and shaft, slider crank mechanism	Input device , Arduino, jumping wires sensors	the machine uses slider crank mechanism to push the biscuit and uses pressurized cream dispenser to apply cream and then uses can and shaft to press the biscuit
5	https://blog.arduino.cc/2016/12/06/the-sandwich-o-matic-will-make-your-lunch-automatically/	In this prototype they are using bread and adding toppings to it as required or available. The bread is first toasted and then flipped into a plate and with the rotating dispenser the toppings are added as ordered then the another piece of bread is kept over it	Dc motor, gears, tray, cream injector,switches	Arduino, sensors,display,NFC,google sdk	receives order via NFC or Voice toasts bread ,adds required toppings ,serves on plate
6	https://www.roboticgizmos.com/cheeseborg/	In this prototype they used an unique way of keeping the bread/biscuits on one another by using an vacuum mouth which keeps the bread,cheese any toppings which have plain surface area and then grill the bread and serve on plate	vaccum mouth,automatic bread, stacker ,motor ,rope crane	Arduino , NFC sensor ,Google SDK Rasberry pie 3, toaster timer	Stacks the bread using vacuum mouth and keeps cheese slices on it and then stacks bread over it and transfers it to grill machine and heats the sandwich and serves on the plate
7	https://youtu.be/IhXl-ZMLrtc	In this video, they are placing the cheese slice in between the breads. It works with the help of mechatronic components, which are controlled using a computer/laptop.	Screws ,Nuts ,Steel sheet with holes,Iron/steel pipe ,Gears	Motors,Jump wires ,Toy servos,Arduino ,LED’s ,Wires	The product can take a bread and place a on plate like thing, and pick a cheese slice and place on it. Again take another bread and place on the slice of cheese and make it a sandwich.
8	https://youtu.be/wUwURh3j07U	this is a very compact yet very useful machine which effectively utilises uses the space and stacks bread and even applies cream	Circular disc ,Nuts ,Steel pipes ,Gears	Motors ,Arduino ,Resistances ,Transistors ,DC adaptor ,LED’s ,Wires ,Jump wire	The product is capable of to make sandwich which can be pressed and it will get a shape.
9	https://sites.google.com/site/automaticsandwichmaker/project-definition	It reduces the steps and clean up time associated with making sandwiches .It works on the basic user inputs.	Steel stand ,Conveyor and belt ,Nuts ,Screws ,Iron/steel pipes	Motors ,Arduino ,Resistances ,Transistors ,DC adaptor ,LED’s ,Wires ,Jump wire	The product makes bread sandwiches with many stuffs, within seconds. It has a conveyor belt which has breads on it and moves till the items are stuffed and other bread Is placed on it.

Basic Components Required
