4.1 Introduction of Jaideep Dal MillJAIDEEP DAL MILL INDUSTRIES is a small scale manufacturing plant of pulse production. It was established in year 1997 and since then, it is working in the field of processing of all type of pulses in Sidhguma industrial area in Sagar district, Madhya Pradesh. It operates its plant in process such as Cleaning, Dehusking, Grading, Conditioning, Splitting, Separation, Sizing, Polishing and Packaging. It is spread in total area of 5610 ft2 includes Dal mill plant, warehouse and office with well-organized structure. It has a production of 150 tons per month which leads it to 1800 tons per year with its small man power. It has multiple distributors in every district and there is a great competition in overall market. This unit is able to fulfil the demand of customers with highly satisfied terms.4.2 Process of Jaideep Dal MillThe Dal mill is an industry to dehusk the pulses and split them into halves and make it available to the consumer ready for use. This chapter will introduce and describe the overall process and facilities used for production of pulse from storing of raw pulse to packaging of finished pulse. Later on in the chapter it will outline of the current layout and workflow for the process used in pulse milling.Pulses are the most important agricultural products of India. Rice and dal milling is an age-old activity. Due to recent advancement in processing technology, the net availability of end products in modern dal mills has been increased to 70-75% compared to 65-66% in traditional dal mills. The dal mill is a process industry to dehusk the pulse and splits them into two halves by make it consumer ready to use. The total raw input would be 200 tons per month which refract husks, cattle field and rejected dal and yields about 75% finished Dal. It has gone evolution from hand process to the latest method involved stone roller, Sheller and polisher by mechanical process. The dehusking of dal and paddy are the same with identical machines. First the grains are passed through sieves for cleaning and then pass through dehusking machine where it is dehusked with the help of stone roller and separated from husk. Hence unhusked pulse is further feed into stone roller where dehusking of left back pulse again passes through the stone roller. The different grades of pulses get separated and collected separately.4.2.1 CleaningThis is the first stage of milling process. In this process the raw pulse is lifting from raw material godown with the help of bucket elevator and passing through 5 sheet vibratory sieves. The vibratory sieves with different size holes sheets help to match the requirement of variety of dal being processed. These vibratory sieves is used to remove the dust particles, stone and aggregate and separate the minute dal, reject raw dal and clean dal through vibratory sieves. It is required to remove contaminated matters from pulse.4.2.2 DehuskingNow, the second stage of pulse milling is dehusking in which the pulse is dehusked twice by using two stone rollers. On its first pass it crack the husk layer and it dehusked about 25-30% of pulse. On its other pass it dehusked about 80% of pulse. So the pulse is further passes through the stone roller for getting maximum dehusked pulse.4.2.3 GradingNow come to the third stage which is Grading, here the shelled pulse passing through four sheet vibratory sieves where appropriate grading is done. Different sieves separate cattle feed, broken dal, donkey or rejected dal and semi-finished dal. The semi-finished dal is now supplied for conditioning.4.2.4 ConditioningIn this stage of process, the semi-finished dal is supplied to the varam machine with tape with the help of bucket elevator. The tape is required to moisturising the dal in the required amount. The moisture pulse is now lying on the roof for soaking extra water with the help of sun drying method.4.2.5 SplittingIn this stage of process, the conditioning dal from roof gets split into two equal halves with the use of Chakki or attrition mill.4.2.6 SeparationIn this stage of process, the split dal are passes through four sheet vibratory sieves and separate the powered dal, broken dal, finished or split dal and semi-finished dal. The semi-finished dal is again passes through the second stone roller and further completes the whole process.4.2.7 SizingIn this stage of process, the finished dal is standardizing as small size, medium size, bold and overflow dal. The bold size dal includes standard size of pulse and overflow dal include unsplit dal.4.2.8 PolishingIn this stage of process, the different sized pulses are supplied separately to varam machine with tape for polishing the dal.4.2.9 PackagingIn this stage of process, the finished pulses are packed to prevent from any damage such as broken or powdering of dal.
