    purge air on the walls of the ilindra.
    The advantages of the proposed device consist in the elimination of dead space, after which the descent of inanimate suspension disappears. The amount of sample taken can be re-determined accurately. It is possible to completely automate the sampling and carry out equipment testing after sampling. The drawing shows the proposed device, section.
    In the bottom cover 1 of the fermentation tank, there passes the sleeve 2, which is firmly connected to the bottom cover 1. The lower end of sleeve 2 has on its inner side a cone that is wedged with a wedge-shaped ring 3 pressed by a cap nut 4. This ring 3 seals the cylinder 5, which is open at the top the end is attached to the bottom cover of the 1 fermentation tank. The lower end of cylinder 5 is expanded and closed. This rasigarek space contains a control piston b, squeezed down by a spring 7. Above this expanded space there is a narrower space with a dosing pore 8 and a closing piston 9. The control piston b and dispensing 01 pistons 8 are connected by a rod 10, which passes through the bottom of the cylinder 5 and at the lower end is provided with a protrusion 11 which controls the pressure air switch 12 and the purge air switch 13. The butt end of the piston piston 8 is inclined so that the sample is well drained into the outlet channel 14. The very bottom hour of the metering piston 8 is fitted with the lowest part of the channel 14. The upper stem 15 is inserted into the inclined end of the metering piston B, on the upper end of which is covered the closing port 9, The upper rod 15 is hollow and in the closing piston 9 has openings 23 directed downward at an angle. The inner wall of the closing porin 19 is inclined. The upper rod 15 is provided with a driving channel 16 located in the metering piston 8, which is connected to the inlet pipe 17 if the metering piston 8 is in the lower position.
    The supply of sterile purge air is controlled by a valve 18, for example electromagnetic, which receives a signal to open from the switch 13 of the purge air. The end of the purge air supply is regulated by a time relay (not shown). Into the expanded space, under the control piston 6, the flow air flows through the nozzle 19, which is controlled by a valve 20, for example electromagnetic, the opening of which
    is controlled by a button (not iokdEgchil; and its closing is controlled by a head 12, which is controlled by a protrusion 11. The open space is connected to a nozzle 21 by a pressure air, which is controlled by a throttle valve 22,
    The signal for sampling is given by a button or a time relay that opens the pressure air supply valve 20. With this air, all three pistons 6.8 and 9 are extruded into the upper position and the suspension from the fermentation tank flows into the space above the metering piston 8. As soon as the pistons 6.8 and 9 reach the upper position, the protrusion 11 touches the pressure air switch 1 that the 1st closes valve 20. Spring 7 pushes out pistons b, 8 and 9 into the lower position when the closing piston 9 interrupts the further supply of the suspension and at the same time the dosirukhtsii piston 8 opens the outlet channel 14 and connects to the supply 17 of sterile purge air. In the lower position of the pistons 6.8 and 9, the protrusion 11 of the forward switch to the switch 13 of the purge air signals the valve 18 to open the supply 17 of the purge air, which the upper rod 15 enters through the holes 23 into the upper part of the space above the metering piston 8 and squeezes the sample into the outlet 14, and at the same time clears the specified space. The flow time of the purge air is determined by a time relay whose time interval can be arbitrarily set,
