2.1.5 Preparation of decoction of soap root

One penoobrazuyuschnh substances used in the production of halva is a concoction of soap root. To prepare the decoction of dry soap root thoroughly washed with water and dust from the ground and soak for 10-15 hours in clean hot water at 60 ~ 80 ° C to soften. He was then cut into pieces measuring 3-4 cm in kornerezke or knife hand. At kornerezke soapy root is crushed to a thickness of 1 cm Chopped root boil 3-4 times with fresh portions of water. Received weak extracts boiled to a density 1050-1040kg/m3. Water remaining after soaking the whole root is also used for boiling the extract. Soap root boil in a copper boiler with steam or heating coil installed under an exhaust hood with a rexinforced rod. Washed and shredded soap root of the load by about? capacity of the boiler, fill with water and begin digestion. In the first portion of water boil the root at a pressure of 4 kg/cm2 steam for 5-6 hours until the broth of dark brown color density of 1050 kg/m3. Ready broth is poured through the lower edge of the nipple or through the boiler (by tilting) in wooden vats or tanks, lined inside with ceramic tiles. When pouring liquor is filtered through a mesh with a hole diameter of 1 mm. Remaining in the pot soap root again fill with water and boil again in the same conditions to a density of about 1010 kg/m3. After this broth is poured into another wooden vat or tank, lined inside with ceramic tiles. After three-and four-digestion each time in fresh water (as above), soap root cooled with cold water and removed from the plant as waste. Taken together, after the second, third, fourth digestion decoctions of the root boiled soap until a dark brown color and density of 1050 kg/m3 - 1040 kg/m3 # The filtered broth should not contain particles of the root and be free from foreign odors. Decoction of soap root density 1050 kg/m3 has 16-16,5% Solids. Since the broth can quickly, in a few days to spoil it manufactured only as an operational need. In the process of boiling from the definition of one and the same amount of extract of the roots yield a density of 1050 kg/m3 is obtained is different, depending on the age of the roots of saponins contained in them. Therefore, before extraction to determine the flow of soap roots to make one ton of broth density of 1050 kg/m3, depending on its extractive capacity as follows: washed, crushed soap-root of 200 g pour 1 liter of water and boil for 4-5 hours. The extract is filtered so that the whole mass of roots remained at the bottom of the tank, which was carried out digestion. The filtered extract was compacted to 1050 kg/m3, and weighed. Cooled down roots again pour 1 liter of water, and again were extracted for 3 hours. The extract was also filtered and compacted to 1050 kg/m3. Weighed. In a similar way to the extraction is carried out for the third time. Required number of soap-root in dry matter is calculated based on laboratory determination as follows: X = (n • 1000): m, where X - the number of soap-root (in dry matter) needed milking produce 1 ton of the extract, kg; n - number of solids in 200 g of washed shredded soap root, kg; m - mass produced by an experimental extraction of broths, kg. To determine the number of roots in nature produce corresponding conversion of dry substances. Example: The resulting soap root has humidity 15%. After washing and soaking humidity it - 25%. At such moisture 0,2 kg sample taken for extraction contained 0.15 kg of dry matter. As a result, experienced a 3-fold extraction of the sample received 0.4 kg of the extract density of 1050 kg/m3. Consequently, for the preparation of 1 ton of an extract from the root of the batch, it would require (in dry substance): (0,15 • 1000): 0,4 = 375 kg Root cellar of soap in kind: (375 • 100): 0,4 = 417.6 kg Consequently, for the preparation of 1000 kg of broth density 1050 kg/m3 of soap root of the batch it is necessary to take 417.6 kg.
