Due to increase in population the need of food products and its daily consumption is higher, hence the food production need to be improvised with latest technology. An attempt is made to produce the traditional Indian snack, “ANARSA” also called as “ATHIRASAM” in a semi-automated manner by integrating the engineering techniques with the conventional procedure of the recipe.

The work deals with extruding the dough of the ‘ANARSA’ into sheets of required thickness and then by cutting it into the desired shape and size. Then the cut dough is transported to the vertical fryer and fried at the suitable temperature. The manufacturing of such machines will reduce the lead time and helps in the mass production of food.

INTRODUCTION

Food industry is one of the blooming industry which plays a vital role in the growth of Indian economy. The food industry comprises of food processing, packaging and preservation by integrating the field of mechanical, material science and bio technology. The most important factor to be considered on the food industry is safety and quality of the food so produced by the machine [2] . In food industry the raw material (agricultural products) are processed and converted into desired foods by undergoing specified techniques.

Here we focus on the design of ‘ANARSA’ machine which is used to produce the Indian traditional snacks called “Athirasam” in a semi-automated way. ‘ANARSA’ is a traditional sweet, largely consumed by the southern Indian states, particularly during the festival seasons. ANARSA is otherwise called as Athirasam, Ariselu, Kajjaya, etc. It is usually made up of rice flour and resembles that of doughnut. The preparation of ‘ANARSA’ in a manual method is complex and tedious. For making the ‘ANARSA’ in the desired manner the parameters such as dough consistency, fermentation period and frying temperature should be carefully maintained. By implementing such machines, the south Indian food recipe can be made world famous by implementing food safety and uniformity (shape, size and taste).

HISTORY OF FOOD INDUSTRY

The food engineering was developed at the time of industrial revolution in late 1850’s. This rapid development of food industry was due to the exponential growth of world population. Food industry mainly concern with the improvement of food processing by experimenting innovative ideas and techniques. The advancement in the field of mechanical, material science and bio technology lead to the development of food industry. After the industrial revolution, the mass production of food products increased because the invention of

It helps to fulfil the needs of the growing population across the world. In the global scenario, India ranks 19 th position in the overall automation projects by the recent survey reported by International Trade Administration (ITA) [3]. There are many companies which uses automated and semi-automated machines for mass production [11] . The urge of food and food products in an innovative way is highly needed, but it does not need the demand of the people worldwide. The need for such automated food production is important and Indians lag in the traditional food production using technology. This idea will awaken the young minds to make a platform for Indian traditional food in the global market.

Though India stands second in the production of food [1] , the on-going process for food industry is still lagging. Indian food industry mainly concentrates on dairy products such as milk, cheese, etc. Hence India is the largest producer of dairy products which was summed by Indian Brand Equity Foundation (IBEF) [4]. In India, Gujarat Corporative Milk Marketing Federation (GCMMF) is the largest dairy producer. If the Indian food industrialist moves on to the traditional food especially on snacks production, India would shine in the global market. In India there are companies like Amul, ITC, etc., produces variety of food products. India contributes 9.8% in the food processing sector during the financial year 2013. The contribution of agricultural and food products manufacturing of India in the period of 2011-2016 is about 11.74% of the total revenue and the Compound Annual Rate Growth(CARG) is about 16.2 billion USD in FY17*, Indian food exports stands about 1.3 billion USD [4]. Thus the commercial and technical need for the development of food industry is indispensable.

SCOPE FOR SNACK FOODS

The diet and nutrition experts agree that everyone should snack between the meal [5]. In the past two decade people across the world were attracted towards snacks. If right snack is offered at right time, it can play an important role in managing hunger and nutrition. Hence the need for the snacks is rapidly growing. For example, the consumption rate of the snack like chips, rolls, etc., are exponentially widened across the world. While coming to the Indian market the traditional snacks also have a good market value. The most commonly consumed Indian traditional snacks are Anarsa, , Pappad etc.

For such Indian traditional snack, we have both nutritional and commercial values. Hence producing such traditional snack at higher level helps in the growth of Indian economy. For producing this kind of traditional snack at mass level, the implementation of current technology and research plays a vital role. The innovation towards the machine which produces these items is also widely required. Thus the scope towards the snacks making machine is huge.

THE DELIGHTFUL MAKING OF ANARSA

It is mostly used dish in Tamil cuisine. It is prepared from the dough made of rice flour and . The making of Anarsa is similar to that of Vada, but only thing is Anarsa is sweet rather than savoury. The Anarsa is mainly prepared at the time of festivals like and Dasara. After fasting in those auspicious days, the first food to be taken to break the fast is Anarsa. It’s been a traditional one for generations together.

BACKGROUND OF THE PROJECT

The Anarsa machine helps the south Indian dish to reach the global market. By making the small modification in the machine, we can achieve variety of Indian snack produced in a single machine. Anarsa is a traditional food that can be made manually hence there is no machine till now. But for the mass production of Anarsa the machine needs automation. This machine will hit the global market like the other machine as maker and maker. The Dosa maker is one such machine made by Shaji, Lohit and Bauri.

FIELD OF INVENTION

The main aim of selecting the field is to address the global needs for food industry. The reason for choosing the food industry is to focus on three major values; they are nutritional values, traditional values and business values. The nutritional value mainly concentrates on human health and immunity of people. In ANARSA, rice flour (rich in carbohydrates and has no fats) and jaggery (contains minerals and vitamin B) are the main ingredients.

The Anarsa is a south Indian traditional dish used during the time of festival. This traditional food has to be brought up in the global market. It is also to attract the foreigners towards the south Indian snack.

MECHANISM USED

In this machine, there are three major mechanisms used to carry out the desired operations. They are,

• Dough sheeting mechanism

• Slip-Flip mechanism

• Oil punching mechanism (excessive oil)

Initially dough is introduced to the dough sheeter where it is made to sheets of required thickness using dough sheeting mechanism through two series of rollers. The dough sheet so produced is cut into required shape and size by roller cutter having required die on its circumference. The dough which is cut to the required shape is sent to the vertical fryer through belt conveyor. The motion of the product in the pan is achieved by constant oil flow from the oil sump at required pressure. For turning the ANARSA in the frying pan we use the twist flipper mechanism. The slip-flips are placed at the end of each pan. Finally, the ANARSA so fried is punched at required pressure by piston in order to remove excessive oil from it.

WORKING PRINCIPLE

In Anarsa machine, the process starts with the making sheets of the pre-processed dough and ends by frying. It consists of dough sheeter, roller cutter and the fryer (Vertical fryer).The dough is made into a thin sheet having thickness of Anarsa’s thickness (about 7mm).The roller cutter has the template of required shape and size of Anarsa about 70mm.The dough from the cutter is sent to the vibratory conveyor where it is segregated into two parts, one is required shaped dough send to fryer and other is extra dough which is send to collector pan. Then dough gets fried in fryer having separate arrangement for tilting. After that the fried Anarsa reaches the press to remove the excess oil. Now, this Anarsa is ready for package.

Figure 5: Flowchart of the Process

The rotating extruders, cutting roller and all other rotating rollers are connected to a single three phase synchronous motor. For heating the oil, two solenoid heaters are fitted in the oil sump. The heated oil is then transported to the frying pan through gear pump [8] .In order to compensate the heat loss during the transportation, the oil is heated to excessive temperature than required. In this machine, for maintaining the optimum temperature in the frying pan,

MATERIAL SELECTION

For food machines, material selection is very essential. Material selection mainly depends on quality and safety of the product manufactured [10] . It also examines the factors such as production cost, availability of the material and ease of machining. We can classify the parts of the food machine into two categories: one is direct contact part and other is non- contact part of the food products. The parts such as fryer, upper belt conveyor, extruder and lower belt conveyor have direct contact with the food and the parts such as frames, conveyor roller, sleeves etc., are non-contact with the food.

For fryer pan in the vertical fryer, the selected material should possess the following characteristics; they are, withstanding high temperature, easy to machining and safer to the food. The temperature range for SS316 is about 100 to 315 o C and it is highly safer to food products. In such case, we can use SS316 steel for frying pan [6] . For extruder, cutter and other contact food parts the same material can be used. While coming to the food contact belts, it is more suited to use Olefin Polymer because of the below reason. The Dough prepared has the sticky and abrasive nature, so the belt material should have excellent surface release & easy cleaning character, greater wear resistance, good thermal resistance and good abrasion resistance, we can use Thermoplastic Olefins (TPO) [9] . Operating temperature range of the TPO is from -40 oC to 150 oC. For the Non-Contact food parts, low grade Stainless Steel SS202 is used which helps in cost reduction.

LEAD TIME AND PRODUCTION RATE CALCULATION

The production rate is defined as number of products in a particular period of time. Production rate of the ANARSA machine depends on the time required for dough sheeter, cutting and frying for each ANARSA and other allowances. To find the oil flow rate in fryer pan, taking the time for frying on both the sides of ANARSA as 70 seconds. Then,

Oil flow rate = Circumference of the pan / Time of frying per stage

Where, the circumference of the pan = 2* π*R.

Here R is Radius of fryer pan = 100mm.

Oil flow rate=2x3.142x100=18mm/sec.

Assuming the oil flow rate is equal to the speed of the conveyor. Hence, conveyor speed=18mm/sec. Also length of conveyor is 570mm where the extruder and cutter process takes place.

www.tjprc.org [email protected] 126 Navin Kumar. G, Rubesh. V, Rakesh Kumar. N & Venkat Prabhu. R

• Speed of the conveyor=(Length of conveyor) / (Time for dough sheeting and cutter for 2 ANARSA).

• Time for extrusion and cutter for 2 ANARSA= 570/18=31.67 sec.

• Time for dough sheeting and cutter for 1 ANARSA= 15.837 sec.

Taking, the allowance value as 5 seconds on the fryer and pressing time to remove excess oil.

• Lead time = (Time for Extrusion and cutter + Time for frying + Allowances)

= (15.837+70+5) = 90.83sec

=0.0253 hr .

• Production rate= 1/ lead time= 1/ 0.0253= 39.35= 40 pieces/ hour.

By increases the number of profiles, the production rate can be increased i.e. if the number of profile increased by two times, the production rate is also increased twice . Similarly, the angle between the profiles on the cutter roller is reduced then it results in increase in production rate.

CONCLUSIONS

As food production industry is growing significantly, the manufacturing of food machines like ANARSA machine will help the local vendors. By manufacturing such food machine, the requirements of automation and mass production can be achieved. It also helps our traditional foods to establish in global market. Thus design and fabrication of such food producing machine is highly essential of the growing population.
