INSTRUMENTATION AND FOOD TECHNOLOGY
INSTRUMENTATION IN FOOD TECHNOLOGY
Food Technology is a science which deals with the techniques and principles involved in processing and preserving the food substances. The application of food science helps in manufacturing safe, wholesome and nutritious food products. The study of food technology is to develop new methods and systems for keeping food products safe and resistant from natural harms such as bacteria and other micro-organisms. Food processing helps in preservation enhances the flavor and reduces the toxins in the food product which results in better distributional efficiency and easy marketing of the food product.
Instrument constantly measure various parameters such as flow, pressure temperature of the process, safety and soon. Pressure sensors are employed in heat processing operations in retorts and extruders. Instruments for the monitoring of level, flow and density include ultrasonic and resonator techniques. The in-line measurement of the rheological properties of many foods is complicated by their high viscosity or non-Newtonian behaviour. Food texture is a complex property which is quantified with a range of techniques. Particle size is important for the rheological properties of foods and their dispersibility as well as for their eating quality. Particle sizing with electrical zone sensing and light scattering techniques is used in the food industry. For example, Beer Brewing requires various steps and process such as correct amount of mixture has to be mixed at right temperature and right pressure and all these in a closed tanks with correct time and humidity etc Similarly, if you are producing biscuits in large quantity then it is necessary that you use right ingredients in the right quantity and all this can be controlled by using various valves and control loops where you control the ingredients, additives etc.
Therefore instrumentation in food technology is alarmingly arising at the fastest pace with the development of The testo 104-IR Infrared & Probe Thermometer , IP65-rated integrated probe , infrared laser , The Testo Saveris 2-T1 etc for monitoring temperature , pressure etc. And the development of even more of the technology in this aspect is very much need and is being approached superfast because food is the most essential need of every human being on earth which indirectly is the one good which always has our country’s economy stake in hand.

ACCELEROMETER BASED GESTURE CONTROLLED ROBOT USING ARDUINO
Robotics has gained a special interest in recent years because it can be adopted to solve a wide range of problems in our modern life. Wireless controlled robots are very useful in many applications like remote surveillance, military etc.
The project is an accelerometer-based gesture-controlled robot, which deals with request from the user through the transmitter part and make a response to it. This can be done by controlling the robot using accelerometer sensor. The sensor initiates the signal and sends it through RF transmitter, and then this signal is received in second part of robot via RF receiver which analyses it and the robot will move in a specific direction.
Motor Driver L293D
9 Volt Battery
In transmitter part an accelerometer and a RF transmitter unit are used. Accelerometer gives an analog output so here we need to convert this analog data in to digital. For this purpose, we have used 4 channel comparator circuit in place of any ADC. By setting reference voltage we get a digital signal and then apply this signal to HT12E encoder to encode data or converting it into serial form and then send this data by using RF transmitter into the environment.
At the receiver end we have used RF receiver to receive data and then applied to HT12D decoder. This decoder IC converts received serial data to parallel and then read by using Arduino. According to received data we drive robot by using two DC motor in forward, reverse, left, right and stop direction

These are the few thing that I have learnt in these past few years of my college life. I just wanted to share these with you guys. I feel life has always a plan for you and believe me or not everything does fall in place one way or the other. I am not saying that you should stop trying and let life take its course, I am just saying don’t be stressed. Don’t try hard to control everything. Sometimes you need to loose balance to find out who you are. And most important thing, believe in yourself. You should love yourself first before loving others. This is because your source of love is you, if you don’t love yourself you won’t be able to give love to others.
Now coming back to ISOI, this is something which just happened to me. Back then I just knew Snehashish bhaiya, we met at our branch meet where all my biomed seniors came to introduce themselves and to get to know us. I did not even apply for other chapters since I had to go home for my sister’s marriage. I was really tensed because ever since I saw these chapters and people wearing different t-shirts and roaming about in the college, made me realize I wanted to be a part of all these things. So I did not know whether I will get into or not because I knew by the time I would come back, all these recruitment process will end for the second semester. But thanks to my luck, I made it into the chapter.
From then on it has been a great journey. I have made so many friends, such adorable cute, dorky friends, some amazing seniors and last but not the least some sweet, loving juniors. The role of event’s head was a tough one, I did not realize it earlier but as time passed by I realized what my responsibilities were. I had my seniors who entrusted me with such an important task. They believed in me and that gave me the strength I needed. I knew that it was not just me but the entire chapter that I had to think for. It would not have been possible without my ISOI fam. I am proud of everyone in my team, be it our board members or our fellow mentors and our juniors.
ISOI has made me what I am today. Being a shy girl, I never had the confidence of approaching someone head on or addressing anyone or leading a group of members. But now when I see myself I see the growth that I had over these past few years due to my experience in this chapter. And I will always be grateful to ISOI for that. I don’t know where I will be in the next few years but I am sure wherever I will be ISOI will always remain in my heart.
Lastly, I would like to wish everyone best of luck for their future. Do what you want to do, never let anything stop you from reaching your goal. And remember, everything is going to be fine.
