ABSTRACT - Solar energy has a silver lining in that it
water during the reeling process. This method not only cooks the shell, but it also fills the cocoon with water to a level of 97 to 98 percent, causing the cocoon to become heavy and sink in the reeling water. Raw silk is converted into standard-sized hanks by re-reeling. Grant reeling is useful for recovering broken thread ends and knotting. Grant reeling divides the hank into many portions that are maintained separately by lacing. The bevel ratio determines the width of the diamond. For finer denier silk, teeth must be utilized in higher numbers. The pace of rereeling is approximately twice that of reeling. As a result, one re-reeling end will be sufficient to manage the input from two reeling ends. Using an upgraded multi-end basin reeling mechanism. It's a Cottage Basin variant that's powered up. The ends of cocoons should be rounded and strong, with no sharp edges. Well-pointed ends are simple to recognise because of their form. Steam is used for cooking, reeling, and cocoon suffocation in specialized steam rooms, thanks to the construction of boilers. The selection of cocoons must be done with care, as any lapse in this area could result in significant losses for the struggling business. Selective cocoon buying on the open market is difficult and imperfect, especially in the lack of established cocoon quality standards and acceptable methods of testing for grading cocoons.
helps to reduce the greenhouse effect, which helps to restore ecological balance in our environment. Solar energy has a lot of potential in the high-energy silk business. Because it is a cottage industry, it relies on firewood and different forms of agricultural leftovers for energy, which has serious environmental consequences and deprives the soil of critical nutrients and organic conditioning material. Cocoon heating is a critical phase in the reeling process, as it is during this step that the silk is extracted. As additional components for the silk reeling unit, a new system for energy efficient management of the silk reeling process has been developed, which incorporates heat recovery unit and flat plate collectors. The energy consumption for cooking, reeling, and re-reeling activities was calculated and compared to a standard method. For the production of 20 kg multivoltine raw silk in a 10 basin silk reeling unit, 1000 , 500 , 400 and 100 L of water are consumed on average for cocoon cooking, reeling, re-reeling, and boiler operations, respectively, resulting in a significant amount of firewood to generate thermal energy for cocoon preparation.. With the combined use of solar water heating, a heat recovery unit, and a boiler, the new, energy-efficient management technique produces 52 percent saving in firewood consumption with a payback period of a 50-year return on investment when compared to the old technique.

Key Words: Cocoon cooking, firewood, heat recovery unit, insulated hot water tank, silk reeling, solar water heating system.
The optimum temperature of 40-45°C of hot water , more effective for reeling. During reeling, the capacity of each basin comprises roughly 40 L of water at 40-45°C. A total of 400 L of water is required for ten basins. To bring the entire water in the reeling basins to reeling temperature and keep it there during reeling, steam energy is necessary. In all of the basins, hot water is naturally cooled, and steam is employed to enhance the cooling effect. The cooling of heated water at 45°C is measured as a loss of 0.07 kcal/L/min heat energy. The concentration of dissolved sericin in basin water increases as cocoons are reeled indefinitely, altering the color of the raw silk produced. It is practiced to avoid the turbidity effect by ten basins, and the reeling temperature is kept at 45°C for eight hours each day. The energy needed by a 10 basin
INTRODUCTION The unwinding of filaments from a bunch of cocoons in a hot water bath onto a reel is known as silk reeling. There are two types of reeling: direct reeling on normal reels and indirect reeling, which involves preparatory reeling on small sized reels and moving reeled silk directly from the reels to standard sized reels on re-reeling machines. The cocoons are only heated until the shell becomes wet on the floating system. Still impermeable to water, allowing them to float in water when placed in the reeling basin. Cooked cocoons dip in water during the reeling process in this technique. This technique involves dipping cocoons in
