Description

The invention relates to the wine industry and can be used in the horse and wineries for the processing of waste wine,

A known method for producing tartaric Lime from bards is a waste of wine-making, including clarifying bards, converting tartaric compounds into a soluble state, precipitating and isolating tartaric acid.

The closest to the proposed Before technical solution is the method of obtaining tartrate lime from bards - the waste of wine production, including the introduction of binder BeigecTB into bard, its clarification and the removal of tartaric acid Compounds with their subsequent precipitation from solution. Extraction of tartaric compounds is carried out on ion exchangers in chlorine form C).

The disadvantage of the known method is that as a result of the treatment with the gluing agents, the bards are incompletely clarified, as a result of which the ion exchangers are quickly contaminated and their exchange ability decreases, which leads to the loss of tartaric acid compounds. In addition, when neutralizing the tartrate solution due to a change in the pH of the medium, a loss of the desired product also occurs.

The purpose of the invention is to improve the quality of bards clarification and increase the yield of the target product.

The goal is achieved by the fact that according to the method of obtaining tartaric lime from the bards-waste of wine production, including the introduction of binder into the bard, its clarification and the removal of tartaric acid compounds, followed by precipitation from the solution, 3-20 mg is added to the bard before / l polyoxyethylene sorbitan monomalmitate or polyoxyethylene sorbitan monostearate, and before precipitating tartrate compounds, the solution is treated with sodium carbonate to pH 5.0-5.5.

The proposed method is carried out as follows.

In the hot bard obtained after distillation of wine materials or from other wine-making wastes, a surfactant based on polyoxyethylated fatty acid esters with 12-18 carbon atoms in the chain and partially dehydrated polyhydric alcohols with 5-6 carbon atoms is added. which use polyoxyethylene sorbitan monopalmitate or polyoxyethylene sorbitan monostearate, in an amount of 3-20 mg /, vigorously mix, incubate for 10-30 min, then the adsorbent and flocculant nt are introduced successively vigorous stirring. The mixture is defended within 2-4 n, the clarified portion is decanted. The clarified bard is passed through ion exchange filters filled with ion exchanger in chlorine form.

The process of ion exchange is controlled by changing the pH of the medium.

After saturation of the ion exchanger with tartaric compounds, the supply of bards is stopped, the resin is washed with water until all impurities are removed, while washing is carried out in countercurrent. The remaining water is allowed to drain, after which desorption is carried out with a solution of sodium chloride. The concentrated solution of tartaric compounds is displaced, for example, by air, the anion exchange resin is washed with water and the bards processing is repeated. The resulting concentrated solution of tartaric acid compounds is heated, treated with sodium carbonate to pH 5.0-5, then neutralized with a solution of calcium chloride. The tartaric lime precipitate is separated and dried.

Example 1. For horse bard obtained after the distillation of vinomatals,. 6 mg / l of polyoxyethylene-benzyl monopalmitate are added, mixed, incubated for 10 minutes, then 1.0 g / l of bentonite and 3 mg / l of polyacrylamide are added sequentially, mixed for 20 minutes and settled for 2 hours. After the separation, the clarified portion of bards from the precipitate is decanted. As a result of processing, the content of suspended substances is reduced: from 1.12 to 0.18 g / l.

The clarified bard is treated on anion exchange resin AN-2FN in chlorine form. After the anion exchanger is saturated with tartaric compounds, the anion exchanger is washed with water until all the contaminants are removed, and the washing is carried out in countercurrent. After displacing the residual water, the solution is desorbed with a 25% sodium chloride solution. The resulting concentrated solution of tartaric compounds (pH 4.08) is heated, treated with soda ash (sodium carbonate) to pH 5.2, and then calcium chloride is added to precipitate tartaric acid (CRI). The precipitate FRI washed and dried. Extraction of tartaric compounds from the initial content is 85.9%.

Example 2. 12 mg / l of polyoxyethylene sorbiton monopalmitate are added to horse bard, mixed, incubated for 10 minutes, then 2.0 g / l of bentonite is added, mixed and settled for 2 hours. The clarified portion of bards is separated from the precipitate by decantation. As a result of processing the content

suspended solids are reduced from 1.72 to 0.21 g / l. The process of treating the light: fended bards on anion exchangers is carried out as described above. The concentrated acidic solution (pH 4.13) obtained after desorption is treated with soda ash pH 5.5 and then precipitated by an ICI by the addition of calcium chloride. The recovery of tartrate compounds is 84.7%.

Example 3. Barda / obtained after distillation of the squeeze diffusion juice7 is treated with 8-mg / l polyoxyethylene sorbitan monostearate. The mixture was stirred for 10 minutes and then 1.5 g / l bentonite and 7 mg / l polyacrylamide were successively introduced.

After mixing, the vinasse is removed by 3 hours. The clarified part of the vinasse from osskashka is decanted and treated on anion exchange resin in chlorine form. As a result of clarification, the content of vesicles decreases from 2.17 to 0.26 g / l. A concentrated solution of tartaric compounds, obtained after desorption (pH 4.3), is treated with soda ash to pH 5.5 and is precipitated with calcium chloride. Extraction of tartrate compounds 86.3%.

The proposed method increases the degree of clarification of wards by 2-3 times and increases the yield of the target product by 14.7-17.6%
