Quality Management System (QMS) is an integral part of enabling Food Safety in Food Manufacturing. It has applicability irrespective of type or quality of processing infrastructure, be it a manual operation or a fully automated production system. In this video lecture, Veena Mishra (Process Engineer at PMG) will discuss the fundamentals of QMS, and it’s purposes and advantages.
Chocolate is also known as the Food of the Gods in Greek mythology. Today, there are thousands of companies and millions of product variants in the Chocolate Industry. Chocolate has become an integral component of our diet. In this video lecture, Veena Mishra (Process Engineer at PMG) will discuss the fundamentals of Chocolate Manufacturing.
Welding is by far the most used technique for joining materials. Despite the advent of new techniques like 3D Printing, etc. Welding continues to be the backbone of all industrial infrastructure. In this video lecture, Nure Imam (Mechanical Engineer at PMG) will discuss the fundamentals of Welding and major Types of Welding.
Concept of Cleaning and Sanitization
Cleaning and sanitization is one of the prerequisite and key element for ensuring food safety and quality of product in food processing industry. Cleaning and sanitation are two different terms having different definition all together. Cleaning refers to the removal of visible dirt or any physical contaminant, while sanitization always comes after cleaning process and focuses more on the removal of any type of microbial contamination, if any.
Need of cleaning and sanitation is
- To prevent transfer of ingredients from same line to avoid chances of cross contamination in case of product change in line production line.
- To Avoid microbial contamination that lead to reduced product quality, harm to health or life threatening circumstances in some cases.
- To ensure sanitization efficiency as soils impacts the effectiveness of a sanitizer.
- To improve plant efficiency as dirt and dust affects production process as well.
Food soils (dirt): are unwanted matter on food-contact surfaces. Soil can be visible or can’t be seen visible. The primary source of soil is from the food product being handled. However, minerals from water residue and residues from cleaning compounds contribute to films left on surfaces. Microbiological biofilms also contribute to the soil buildup on surfaces. Types of soils can be fats, oils & greases, proteins, carbohydrates and starches, lime scale, rubber marks, corrosion deposits, adhesives, inks & dyes, algae and fungi.
Cleaning Areas: Apart from food contact surfaces various other parts of the plant are to be cleaned and sanitized to maintain a sanitary environment for food processing. Food Contact Surfaces (equipment surfaces, tables & preparation areas, conveyors, utensils, bins & totes, packaging materials), outside of equipment (body, pipelines) and environment (floors, drains, walls, light fixtures) require separate cleaning procedure. Equipment design and plant layout should be considered from a clean ability perspective. One needs to reach around and under equipment to clean it properly.
Sanitization: Foremost step for abiding the cleaning procedures are to make them available to everyone. Sanitization Standard Operating Procedures (SSOP’s) and instructions should be written step by step on cleaning equipment, process lines, environmental areas & master sanitation schedules. Sanitization can be achieved by various means either by thermal or chemical sanitization. Thermal sanitization involves the use of hot water or steam for a specified temperature and contact time whereas, chemical sanitization involves the use of an approved chemical sanitizer at a specified concentration and contact time.
Cleaning Procedure: Equipment classification can be done with regard to cleaning method as CIP (Clean in Place), COP (Clean Out of Place) and manual cleaning. Mechanical cleaning often referred to as clean-in-place (CIP) requires no disassembly or partial disassembly. Clean-out-of-Place (COP) involves partial disassembling and cleaning in specialized COP pressure tanks. Manual cleaning requires total disassembly for cleaning and inspection.
Different parts of the plant require different types of cleaners. For E.g. CIP system does not require cleaners that foam as much as manual cleaners. Sanitizers usually have a period of effectiveness that only lasts for several hours, so if you sanitize the equipment after cleaning it the night before, you may need to sanitize again just prior to processing. The selection of cleaning & sanitizing chemicals for use in a food processing facility depends upon soil type, surface type, method of cleaning being considered (CIP/COP/Manual) and water quality.
Steps for cleaning and sanitization include
- Dry Cleaning: simply using a broom or brush to sweep off food particles and soil from surfaces
- Pre-rinse: using warm water (100-120°F) to remove small particles missed in the dry cleaning step and prepares surfaces for application of detergent
- Wash: removes all soils by following all SSOP’s for cleaning procedures and chemical selection. Factors that are to be considered are time, action, concentration and temperature.
- Post-rinse: removes detergent and Chlorine. There can be acid rinse if required by using acidified water. Acid removes mineral and prevent mineral deposition as well.
- Sanitize: reduces the number of microorganisms on the surface. Before use the surface needs to be sanitized and pre requirement before sanitization is that surface should be clean and free of any form of dirt.
Facilities not cleaned regularly have potential safety risks due to constant spills & falls. It has positive finance response, by reducing waste from spoilage can significantly extend the life of equipment and machinery. The psychological benefits & confidence of clean, hygienic equipment & tidy surroundings have significant impact on both worker satisfaction and customer confidence. Although it may not be common knowledge, there are often legal requirements for food facilities to clean surfaces and equipment to a specific standard.
1. The slow and steady wins the race.
Yes, we all know and understand this quote like it’s common sense. But wait, actions create value, not words, not knowledge. Did we ever take a moment off to introspect whether we are really enacting this principle? Do we consciously allocate tasks, in our multi-tasking life, in “slow and steady” deserving category and rest? Or are we just steadily slow in all the work we do, and paradoxically regard our inefficiency as a core competency. Of course, we don’t have the time to think and answer these “unproductive questions”, and “results” are what matter in the end. We don’t want to be the slow turtles, we want to be fiery tigers, don’t we?
Results matter, but when logic and systematic thinking is betrayed, chaos is the dead end. Like a Ponzi scheme, the ride up is extremely cheerful. Unless we understand WHY we are doing it, knowing WHAT and HOW we are doing it, is like boating with the stream with no oars. Once the stream turns turbulent, we are helpless. Devoid of options and logic, we blame the waters, we rue the spent years it took to build the boat, and we pray that we don’t end up in a waterfall. And therefore, being Slow and Steady means being in command, with long term objective in sight, aligned short term objectives, and actions to back all of it. Being slow and steady means knowing 20% tasks which matter the most, and concentrating 80% of our energy and efforts on those.
Sometimes we wonder this quote is to idealistic, probably applicable up to the Utopian world of high school and college, and much too distant in the real world chaos. Early space travel had a probability of one failure every nine attempts. Before the successful Apollo 11, out of a total of 71 recognized attempts made, 70% failed in their missions. Had the scientist not followed a logical & systematic approach, out of the 41 missions after Apollo 11, 31 would not have been successful.
Facebook, Twitter, Youtube, WhatsApp, and similar are called disruptive technologies; they disrupted the existing game and the playing field. Therefore, to achieve success we must first identify our game and our playing field, and then selectively take up only those activities which positively disrupt our chances of success, rest all are distractions.
2. Fast and consistent will always beat the slow and steady.
It is good to be slow and steady, but it is better to be fast and consistent. Being fast and consistent allows for immensely greater value creation from the same set of resources, compared to being slow and steady. It demands greater focus, unrelenting attitude, and efficient diligence while managing and minimizing the risks. A well executed fast and consistent approach leads to definite differential gains, unlike say stock markets, where again we are boating with no oars.
Fortunately, the 21st century is intrinsically fast. Technology has made every task faster, except may be sleeping – one still needs a good sustainable eight hour sleep. 90% of tasks are automatically and repetitively done by machines, we only need plan, organize resources, and ensure the whole system is up and running. However, a consequence of majority of tasks getting automated is that, we end up with a very minor scope for making mistakes. And therefore, unfortunately, the learning curve to becoming consistent has turned quite steep, and the path of consistency has very low margin for error.
A gradual and sustainable path to becoming consistent is, putting our 100% efforts in the job or not doing the job at all. When we give our best, we end up understanding our weaknesses and improvement areas. When we give our best, we never regret our actions, whether we end up with success or failure. Absence of regret & negativity alchemises into positive and confident attitude, with sharper, insightful and pro-active instincts. And finally we end up with the secret elements of becoming consistent; by being insightful and pro-active in our thoughts and actions.
3. First identify your core competency and then change the playing field to suit your core competency.
In the early days of Google Docs, Microsoft was (and still is) the world leader in Document Editing Software (DES) business. Microsoft had the most advanced suite of software (Word, Excel, Powerpoint, Project, Note, etc.) built over expertise and experience of more than 15 years. Clearly capturing the market segment and creating a revenue stream by developing a new DES, superior and better than Microsoft Suite, was an unrealistic task. DES was undoubtedly Microsoft’s core competency and not Google’s.
So Google identified their own core competency, i.e. Gmail User Base. They developed a simple document editing interface, integrated it with their existing email-portal, and offered it free of cost to its entire user base, wherein Microsoft was charging $100 per user per year. They literally changed the game: revenue from advertising, not from software, and the playing field: their own huge user base, not Microsoft’s. Today, Google has Google Docs user base of 120 million, and substantial market share of cloud services as well.
What we can learn from this anecdote is, despite the individual brilliance we may possess, instead of trying to do everything, identifying one’s core competency and building upon it is the sure-shot ladder to success, as no one else can match it or do it better. Being jack of all trades is great in early part of one’s career, but to climb higher places we must become master of some.
4. It’s good to be individually brilliant and to have strong core competencies, but unless you are able to work in a team and harness each other’s core competencies, you will always perform below par because there will always be situations at which you will do poorly and someone else does well.
Being good or better at something/ multiple things spins off, more often than not, into an illogical conclusion that we can do everything, as good as others if not better. This becomes extremely counter-productive in a team environment when we stop acknowledging the competencies of individuals. On one hand, the disillusioned super-competitive individual gets loaded with far more work than he can manage, eventually damaging his performance in his core-competency field as well. On the other hand, the apparently competency-less individual labors on, without motivation or desire to perform, and ends up with inferior results.
The very contrasting nature of 20th and 21st century compared to earlier times has been, One-Man-Shows/ One-Man-Army concepts don’t work now; scope and complexity of work has gone beyond capacity of a single individual. Even artists need outsourced expertise of sales, marketing, IT support, etc. to make a living. Nevertheless, to turn a blind eye to a blatant fact is another unique human capacity. The hierarchical nature of organizations, categorizing people into managers, executives, officers, etc. worsens the whole problem even further. However, we are now also seeing various start-ups and large companies working with a flat structure and avoiding the kingly-times hierarchical setup, wherein justifiably discipline was foremost requirement.
Situational leadership is the leadership style that produces results most effectively and efficiently in today’s world. It encompasses knowing the strengths, weakness, and potential of the team members, and timely empowering the most suitable person to take lead, basis need of the hour. Even though the internet age and education industry has made information and human resources abundant and cheap, managing stakeholders, scope/ time/ cost/ quality constraints, and extracting the right results via a finite set of people is more challenging than ever. Adopting Situational Leadership is the need of the hour.
