Description

 The invention relates to the food industry, namely the manufacture of bulk instant powder.

A known method of processing raw mummy, comprising the stages of: dissolution-extraction, sedimentation, filtration and evaporation at atmospheric pressure [1]
The disadvantage of this technology is the following: the duration of settling, insufficient degree of purification, as well as the prolonged exposure to mummies of high temperature. Productivity 3-4 l / h. The processing of raw 10 days. The output of 100 kg of raw mummy 8 kg of purified.

 The purpose of the invention is to increase the yield and degree of purification of the drug, as well as the preservation of biologically active substances.

 The goal is achieved in four stages.

 1) Extraction according to extractants. The original raw mummy is poured with 10-20-fold amount of purified water (FS 42-2614-89) and left for 12 hours for extraction, stirring the mixture every 2 hours for 15 minutes.

.2) Cleaning. Primary cleaning of stones, sand, plant debris and other impurities is carried out on a coarse filter with a hole diameter of not more than 1 mm. Further cleaning is carried out on a flat-plate ultrafiltration unit of type A1-OUS with membranes of type UPM-P with a diameter of 500

.

3) Concentration. The purified solution with a solids content of from 0.8 to 1.2% is subjected to concentration on a vacuum evaporator type VP-1200 to a solids content of at least 15%
4) Drying. The resulting solution is dried on a spray dryer USK-201 or in a vacuum dryer. In the spray dryer the drying is performed in the following modes:. The temperature in the upper part of the dryer chamber is not more than 230 ^C and the bottom at least 140 ^C. In a vacuum drier the temperature not exceeding 70 ^{° C} for 12 hours, the product was dried grinding in a laboratory mill and passed through a sieve N 23.

 PRI me R 1. Take 100 kg of raw mummy, pour 2000 kg of distilled water, leave for 24 hours, periodically stirring every 2 hours for 15 minutes. After which the mixture is left for 2 hours at rest for precipitation.

 The liquid part is decanted and passed through a nylon pre-filter with a pore diameter of 0.5 mm.

 The volume of the liquid part after the primary extraction is 1500-1600 l.

 The precipitate and the mass remaining on the filter are mixed and 1000 kg of distilled water are added for secondary extraction, left for 12 hours, periodically stirring every 2 hours for 15 minutes.

 Next, the secondary extract is separated from the precipitate by passing through a nylon filter. After secondary extraction, 800-900 L of filtrate is obtained. The primary and secondary pre-filtered extract are mixed and sent to an ultrafilter for fine purification.

. Производительность ультрафильтрационной установки по очищенному раствору мумие 800-1000 л/ч. Выход очищенного раствора мумие 200-2300 л, содержание сухих веществ 0,8-1,2% Отходы при ультрафильтрации составляют 100-150 л.Thin purification is carried out on a flat ultrafiltration unit with half-sulfonamide membranes, pore diameter 500

. The performance of the ultrafiltration unit for the purified mummy solution is 800-1000 l / h. The yield of the purified mummy solution is 200-2300 l, the solids content is 0.8-1.2%. Wastes from ultrafiltration are 100-150 l.

The purified mummy solution is concentrated in a vacuum evaporator to a 40% solids content. Evaporation mode: vacuum 0.6-0.7 atm, respectively, temperature 70-75 ^о С. The concentrate is dried in a vacuum dryer to a residual moisture content of 4%
Drying modes: a vacuum of 0.8-0.9 atm, respectively, the temperature of 50-60 ° ^C. The dried material is purified mumie pieces, yield 22-24 kg of dry product.

 Next, the chilled pieces are crushed by grinding in a mortar to a powder state, sieved and packaged in two-layer plastic bags.

 The yield of the finished product, the mummy powder is 24 kg. The resulting product is a brownish-brown powder, tart, specific odor mummy, bitter-burning taste.

 The proposed method in comparison with the prototype can be reduced to 3 days. production process, increase the yield of the finished product to 24 kg from 100 kg of raw mummy. Productivity is 800-1000 l / h.

 In addition, the resulting mummy powder retains all low-melting components (essential oils, trace elements, amino acids, etc.). The resulting powder is convenient to use, easily soluble when mixed with other components.

 The proposed cleaning method is more productive and allows you to conduct the process in a continuous mode, with automatic control of the main technological parameters.

 A high degree of purification during ultrafiltration and further processing under milder temperature conditions make it possible to obtain a high-quality product and guarantees the preservation of biological activity.
