Abstract

 A device for selecting drone larvae, characterized in that it is equipped with a flask with a stopper for collecting biomass from the larvae, while three glass tubes are inserted into the stopper, to which plastic or rubber tubes are attached, one connected to a vacuum generator, the second connected to a glass tip in the form of a pipette-shaped tube with an outer diameter of 7 mm and an inner 3 mm, having a blunt polished end, and the third is bent at a right angle.

Description

The invention for a utility model relates to the field of processing beekeeping products and, in particular, to the preparation of the therapeutic and prophylactic drug “Bilar in the form of paste from drone larvae.

A non-traditional drone larvae apiproduct is known - drone larvae homogenate (GTL), which has therapeutic and prophylactic properties and is recognized as more effective in comparison with synthesized traditional medicine in the treatment of tuberculosis (Pochinkova P, 1986; Bergmann HH, 1990; Shi-Gen-Lee , 1993, Lebedev, 2003).

A known method of producing GTL manually by extracting drone larvae aged 7 to 9 days from wax cells using tweezers. This method is widely used in the production of GTL and other products from open bee brood larvae. However, manual selection has many negative factors affecting the biological activity of the resulting product. So, bees are shaken from the frames with drone larvae in the hive, the frames are transferred or transported in a portable box to the laboratory or the isolator for no more than 1 hour at a time at ambient temperature. It is allowed to transport frames with larvae over a considerable distance using ice thermoses or insulated chambers.

The beekeeper laboratory assistant places the frame on the table and manually picks 7-9-day-old drone larvae with tweezers. The selection process must be carried out quickly without damaging the drone cells. In this case, there is a large loss of raw materials and not careful selection of the contents of the cell. Young larvae are returned to the bee family for rearing. The frames after selection of larvae are reused (Grechka G.N., 2007).

The disadvantage of this method is that the process of selecting larvae is laborious, it takes more than an hour and a half to get the larvae from one frame, and it is known that in one hour of GTL exposure to light at ambient temperature, its biological activity is reduced by 70%.

The objective of the invention is the preservation of the quality of raw materials and accelerate the selection process of larvae using a mechanical device.

The device for selecting drone larvae is characterized in that it is equipped with a flask with a stopper for collecting biomass from the larvae, while three glass tubes are inserted into the tube, to which plastic or rubber tubes are attached, one connected to the generator, the second bent at a right angle, the third is connected to the glass tip in the form of a pipette-shaped tube with an outer diameter of 7 mm and an inner 3 mm and having a blunt polished end.

The proposed device allows you to maximize the quality of biologically active raw materials due to the fact that there is no contact with the main oxidizing agent - air and the selection time is reduced to a minimum, and finding raw materials for more than 1 hour in environmental conditions kills its activity by 70%. When using this device, partial grinding of the larvae to biomass occurs, and with the further production of bilar products, the grinding stage is excluded.

The figure shows a General view of the device for the selection of drone larvae.

The device for selecting drone larvae consists of a glass flask (1), into which the larvae are drawn and accumulate (2). The flask is tightly closed with a rubber stopper (3), into which three glass tubes are inserted: one (4) is connected to the generator (5) using a plastic or rubber tube (6), the other (7) is connected to the glass tip (9) by a tube (8) ), which is directly inserted into the drone cell with the larva (10), the third is bent at right angles to create a vacuum (11). The tip (9) is a glass pipette-shaped tube with a blunt polished end, the outer diameter is 7 mm, the inner 3 mm.

The device works as follows: On the table, a frame with larvae (12) is installed at an angle of 10-15 gr., The generator (5) is turned on, a vacuum is created in the flask (1), which allows using the tube with a tip (10) to suck out the contents of the cell ( 10) and draw the resulting biomass from the larvae into the flask.

The comparative technical characteristics of the indicators when collecting larvae with a manual and mechanical device shows that the selection of larvae from 1 square of the frame area is significantly accelerated - 77.5 s versus 137.5 s, which speeds up the selection of larvae by almost 1.7 times, which is very important for preservation biologically active substances in raw materials. The degree of grinding is also higher with mechanical selection compared to manual.

Thus, the proposed device for producing a paste-like bilar product from drone larvae can reliably reduce the time to obtain raw materials by 1.7 times, which is very important for preserving its biologically active substances.

A useful model for a device for selecting drone larvae can increase the efficiency, productivity and safety of the method and obtain environmentally friendly raw materials with maximum preservation of quality.
