Description

The invention relates to a process for obtaining foliar biofertilizers together with microcapsules with essential oil components and compositions of foliar biofertilizers, containing these microcapsules together with components of mostly natural origin.

Numerous processes are known for obtaining microcapsules with continuous essential oils, having uses in the food and textile industry.

Such a process consists of incorporating a solution of essential oil and ethanol into collagen hydrolyzate, homogenizing it, adjusting the pH to 7.4 with sodium hydroxide, adding distilled water until the final composition reaches 1.5 ... 10% collagen as dry matter, followed by cross-linking and microcapsule drying by lyophilization or atomization (RO130962). There are presented microcapsule compositions with essential oils and collagen, in the form of spherical powders with diameters of 2-30 pm, used for the functionalization of textile structures (eg socks).

The invention has disadvantages related to the simplistic conduct of the micro-encapsulation process, drying by atomization of microcapsules can cause their degradation due to high temperatures (eg 230 ° C), and drying by lyophilization implies a significant energy consumption related to the vaporization of a large amount of water.

An invention relates to an integrated system and a process for obtaining extracts with the role of foliar biofertilizer / bioinsecticide in organic farming (RO131209). The process consisted of the extraction of the active substances from the plant material at a temperature of 37 ° C, with five cycles of extraction, for 600 s, at a high pressure of 8.7 bar and five cycles of low pressure of 1.25 bar, with each five quasi-dynamic cycles, each for 520 s, with the countercurrent circulating the solvent during high pressure cycles.

The raw materials and proportions used to make the respective compositions are: 15-35% liquid Bacillus extract, 10-30% algae extracts; 5-25% amino acids; 0.05-0.5% Phytohormone Type A 2018 00167
