What is Lentil Milling?

Lentil milling is the process of removing the outer skin of the lentils and, further, the lentil grains are divided into two equal halves. It also involves washing, shaving and sorting of the lentils. Some of the activities in lentil milling include grain cleaners to filter out impurities and Dehuller for removing the outer skin in the lentils. Roller processing or hammer processing is used to crush lentils into fine flour or divide them into two halves depending on the Lentils product being developed. The output of the sifter is that it assists in maintaining equal quality size of lentil flour The use of food processing machines like the polishing machines also improves the physical appeal of the split lentils. Weighing and packaging machines with proper packaging and labeling of lentil products being put in air-tight bags or tins. Production control systems keep track of every process in the manufacturing to guarantee the production of an accredited quality and safety product.

Lentils Miling Setup

  • Understanding the Market
  • It will be crucial for any market to determine who its market is before extending its facility. There are many types of lentils and all of them are processed in somewhat different ways. Consider factors like:
  • Type of Lentils: Some of the most common types are red lentils, green lentils, yellow lentils and brown ones. Each has its own computation and distribution characteristics and consumer preferences.
  • Product Form: Will the hulled lentils you produce stay whole, be split or will they undergo processing to become ground lentil flour? It must be noted that each type of lentil requires different equipment, as well as contains specific processes in its production.
  • Organic vs. Conventional: If you are starting to sell organic products, you need to have sub-siloing and other certifications to ensure that organic and inorganic products do not mix.
  1. Lentil Processing Workflow
  • Lentils go through an important series of steps starting from cleaning and dehulling, grading to packaging. Here’s an overview of the core stages:
  • Cleaning: The process of cleaning lentils by washing them and cleaning them from any unwanted material such as stones, dirt and the likes.
  • De-Husking (Optional): The process of dehusking the lentil to get split lentils.
  • Splitting and Polishing: In certain varieties such as split red lentils, one is taken through a process of dal splitting the lentils into two halves and polishing.
  • Grading: Arrange the lentils in size so that they are all of a size so that they cook evenly so that when marketed, they meet the required sizes.
  • Color Sorting: The opti-sort system helps on sorting out the greenish, spoiled or otherwise undesirable lentils.
  • Packaging: After the lentils have been sorted, they are put in bags ready for sale to the public or to any wholesale buyer as they come prepackaged ready for use.
  1. Plant and machinery for a Lentil Processing Unit
  • This means that the right machinery has to be chosen to avoid compromising of the quality of the end product as well as productivity. Below are the essential machines needed for lentil processing:
  • Pre-Cleaners: Employed for the purpose of removal of large foreign matters such as stones, sticks and leaves from raw lentils. This is important in avoiding damage of your processing machinery by debris.
  • Destoners: Basically carried out to ensure that other interlocking materials such as stones or any other denser material are free from the aggregates before they are removed.
  • De-Hullers (For Split Lentils): When it comes to split lentils, de-hullers bare off the outer skin from the lentil, and then split into two equal halves.
  • Grading Machines: These are common in separating the lentils by size so as to produce equal-sized lentils in the market.
  • Optical Color Sorters: This advanced technology is employed with a view to identify and eliminate either discoloration or defected lentils. In the production of quality products, this step is crucial fore maintaining high standards of the final products.
  • Polishers: As applied to enhance the beauty of lentils, especially in high-quality markets where polished lentils are most preferred.
  • Packaging Machines: Coordinates packaging specific to retail or wholesale quantities to guarantee the product is packed in moisture-proof and air-tight packs.
  1. Optimizing Processing Stages
  • Lentil processing requires efficiency and high quality. Fine-tuning each of these steps will ensure that you gain the highest yield as well as conform to the required quality of the final product.
  • Pre-Cleaning and De-Stoning: Most of these steps are critical in order to eliminate any unwanted material while making sure the processing equipment is not harmed in the process. High-efficiency pre-cleaners and designers minimize the need to sort the lentils by hand.
  • De-Hulling and Splitting: In the case of split lentils it is necessary to control the process of de-hulling effectively. Excessive de-hulling poses a threat to high breakage, hence a low yield while moderate de-hulling compromises the quality of the final product.
  • Color Sorting: This makes the use of optical sorters vital in order to guarantee that high-quality lentils are released to the market. This method reduces the chances of selling lentils that are small, or have a wrong color, which may affect their premium or export value.
  • Polishing: Although polishing is extra, polished lentils are desirable for better markets such as premium markets or export markets. Polishing adds a smooth and shiny outlook to the lentils to make it more attractive to consumer’s eyes.
  1. Promoting Adherence to the Food Laws
  • Food safety laws govern the processing of lentils as lentils processing units are classed as food businesses. They include quality control measures since this is a critically sensitive area to consumers and thus requires an appropriate level of standardization.
  • Licensing and Certifications: Havc license (India) and also ISO22000 or HACCP certification for food doing business in the nation or internationally.
  • Organic Certification: During the processing of organic lentils, it is advisable to have an organic certification to the facilities used to process the lentils to avoid mixing of organic products with nonorganic products.
  • Traceability: It is important that a traceability system be put in place to track the source of lentils, batches that were processed, and any channels through which it was distributed. This system also provides the ability to find the root of a problem to summon a product recall or a problem originating from your company or your suppliers protecting your customers and yourself.
  1. Energy Implications of Processing Lentil
  • Cleaning, splitting, and polishing may be expensive in terms of energy consumption during lentil processing. Here are some ways to improve energy efficiency:
  • Energy-Efficient Machines: Source efficient pre-cleaners, de-hullers, and sorting equipment that are conserving but reliable in their efficiency.
  • Automation: Introduce automation systems that are used to track in real-time the flow of grain, power usage and tracking the performance of machines. Automated systems decrease energy consumption whilst increasing efficiency.
  1. Managing By-Products
  • Lentil processing produces several by-products, such as husks and bran, that can be utilized to improve sustainability and add value:
  • Husks: Lentil husks can be sold for animal consumption or can be employed for generating bioenergy.
  • Bran: Lentil bran is another product that has high fiber content and should be sold to food manufacturers for a reticular few foods.
  1. The Strategies And Styles Of Packaging For Different Markets
  • After as discussed above through the process of cooking, lentils require packaging in order to have proper pack that can enhance the shelf life and quality of the food. Packaging should be tailored to meet the needs of both retail and bulk markets:
  • Retail Packaging: In some cases they are contained in polypropylene (PP) or moisture-proof bags or pouches of 500g to 5kg. Consumer packaging containers need to be sturdy, desiccant and tamper proof to ensure they do not get contaminated.
  • Bulk Packaging: However for bigger consumers like food processing companies, food exporters Lentils can be packed in 20-50 kg bags. These bags should be in a position to ensure that the product does not spoil via storage or whilst in transit.
  • Vacuum Packaging: For premium markets, vacuum packing or modified atmosphere packing such as MAP should be used as they reduce oxygen concentration thereby greatly reducing chance of spoilage
  1. Scaling Up for Future Growth
  • Once your lentil processing facility is operational, it’s important to plan for future growth and expansion:
  • Product Diversification: The other pulse products that can also be produced include chickpeas, beans, or peas so that the business targets new markets.
  • Private Labeling: >Contract with supermarkets to purchase own brand lentils in their supermarkets to expand the market share.
  • Export Markets: Lentils are in high demand in the global market, especially in India, Turkey, and Canada. Getting the right certification and developing an export capacity will enhance your business immensely.
  • Technology Upgrades: When you start producing higher quantities of products then shifting to high-end equipment and automated machinery will lead to an overall increase in productivity, a decrease in operational cost and an overall increased quality of production.
