Description

Raw opium contains 30-50 moisture and is susceptible to biochemical and microbiological processes.

During transportation and storage of opium raw material, the morphine content in it is slowly reduced under the influence of feminine processes. The gases released during fermentation complicate the selection of containers. Mold, the image of mycelium and spores, lowers the commercial quality of opi. The putrefactive protissies arising from long-term storage of opium-raw material can lead to its complete disintegration.

In order to combat bioprocesses, raw opium, under production conditions, is sun dried and turned into briquettes with a moisture content of 12–16%.

Sunscreen drying of opium cheese has a number of significant drawbacks.

The bitch of opium cheese is made handicraft, during the season it is extremely stressful, using a significant number of workers and money.

Usually, raw opium is diluted with water and unmounted in a mixing tank into a homogeneous semi-liquid mass.

The opium mass, by hand, is spread with a thin layer (1-2 mm) on large sheets of parchment exposed to the sun. As it dries, the operation is repeated up to 12-15 times. The so-formed carpets are cut into briquettes.

The drying of the opium cheese is practically carried out by the preprocessing plant and is possible only after 1-2 months after receiving the opi from the supplier. During this time, raw opium has had time to undergo a number of changes that reduce its commercial qualities.

The drying and hardening briquettes of opi, having entered the chemical factories for the manufacture of alkaloids, are subjected to water maceration and extraction, i.e., the effect is re-dried.

According to the invention, in order to prevent putrefaction and enzymatic processes in opioid, it is proposed to use phenol as a preservative in a liquid form (100 parts of phenol and 10 parts of distilled water) to raw opium in an amount of 0.5-0.8 %

A comparative study of the various batches of opium cheese processed by the proposed method showed that the content of morphine treated with phenol-treated opium raw material remained constant, and the processes of fermentation, rot and mold were not observed, while in batches of opium-syrup untreated with phenol, after prolonged storage (3–12 months), a decrease in the morphine content by 0.47-1.53% and damage by a solid mold was detected.

In practice, canning of opium cheese with phenol can be done at receiving points and raw opium can be transported to

Himfarmzavody, mine primary treatment of solar drying.

The selection of averages, storage and analysis is technically facilitated and refined.

Subject invention

The method of preserving opium raw materials in order to prevent the occurrence of putrefactive and enzymatic processes in it, which is based on the fact that phenol is used as a preservative in an amount of 0.5-0.8%.
