The invention relates to devices for distributing air to bones for the yeast of predominantly whey and can be

used in dairy and microbiological industries.

The purpose of the invention is to simplify the process of adjusting the air flow rate and increasing its stability,

The device provides for the supply of air to the fermenter along the technological branch with direct control of the flow rate and removal of its surplus along the discharge branch with a change in the flow rate in inverse relation to the flow rate in the process branch when it stops or changes the air flow through it. The total air flow is directed along several process branches; along the diverting branches, flows are directed, the maximum cross sections of which are equal to the maximum cross sections of flows in the adjacent technological branches, in the process of adjusting the flow sections are changed in inverse proportionality, and in the discharge branch they create counter pressure equal to the pressure of the serum column in fermenter,

This can be accomplished with an air distribution unit containing a process air duct with a regulator, connected on one side to an air source, on the other to an enzyme-concentrator, and an exhaust duct with retractable ventilation. At the same time, the discharged air overcomes the resistance of the movable element of the exhaust valve 25, creating a back pressure equal to the pressure of the liquid column in the adjoining fermenter, due to the fact that the mass of the mobile element with the sealing gasket is equal to the product of the pressure of the liquid column by the cross-sectional area of the duct. The movable element moves under the influence of air along the vertical guide 31 upwards, 6 or more.

a guiding body associated with the regulatory authority on the process air duct.

All technological air ducts are connected to an air source by means of a distribution chamber, the regulator in the technological air duct is made in the form of a rotary damper, and in the outlet, made of the same section as the technological one, in the form of a rotary damper with an automatic discharge valve installed on the vertical duct section, located behind the damper in the course of the air, and including a movable element with a sealing gasket, mounted on a vertical rail up and down1, while the mass of the moving element with a gasket does not allow the product of the serum column pressure in the fermenter to the duct cross-sectional area, and the butterfly valves on the connected process and outlet ducts are set in antiphase and fitted with levers that are interconnected goy

The device contains a distribution chamber (collector J 1, performed in the form of a conical distribution

on the one side, through air duct 2, to a source 3 of air (a blower), on the other side, through technological connections 4 8, to air consumers (fermenters 9-13J,

Each process pipe is equipped with a rotary valve 14, connected by means of a lever 16 fixed on its axis 15 with a lock 17.

Attached to the process connections are discharge pipes 18-22 of the same cross section, each equipped with a similar valve 23 and installed behind it along the air flow in its vertical section 24 by an automatic exhaust valve 25

The rotary valve 23 of each and the outlet pipes 18-22 contains a lever 27 fixed on its axis 26 and connected by a lever 28 to the lever 16 of the valve 14 of the associated technological pipe.

The automatic exhaust valve 25 contains a movable element 29 with a sealing gasket 30 mounted on a fixed vertical guide 31 with the ability to move up and down, a horizontal head 32 for interaction with the gasket 30 and an exhaust port 33. The mass of the element 29 can be adjusted by inserts 34,

Due to the fact that during the whole yeast process the level of the fermentation in the fermenters 9–13 is constant, the volume of air supplied by the blower 3 is constant, the system can be adjusted once and for all working fermenters . However, during the operation of the device, it is periodically necessary to turn off the air supply to one or several fermenters (for example, when unloading the finished product, washing and sterilizing the fermenters, loading the original product). Assume that when all the fermenters are working (the initial version), the total flow rate

the air passages through them increase (.Gl G, G TvPv) o Even more difference is obtained with a smaller number of consumers. However, both small expenses and large ones are unacceptable for the fermentation process. At low flow rates, the intensity is low, and high flow rates lead to product losses due to abundant foaming and entrainment of it in the form of foam into the atmosphere. Therefore, it is necessary to maintain the former distribution of costs across the fermenters. The damper 23, together with the valve 25, forms a flow control system on the outlet branch pipe, and the valve serves to counteract the free exit of air through the exhaust hole, since, due to the insignificant resistance of the ducts adjacent to the damper, a significant part of the air would go in that direction, and the air flow through the active fermenters would be significantly reduced. The valve should create air movement resistance equal to the resistance of the column of sy- 3g cranks in the fermenter, with the same sections of ducts the air pressure opening the valve should be equal to the pressure of the column of liquid in the conjugated fermenter, 40

with gasket is equal to the product of this pressure by the cross-sectional area

The air distribution is carried out in the following way. The total air flow from the blower is divided into process streams of various flow rates (depending on the amount consumed in the fermenters) and sent to the fermenters. If it is necessary to stop one of the fermenters, for example 13, the air flow into it is stopped, and this flow is directed through the exhaust duct, providing the previous flow rate by creating a counterpressure equal to the height of the serum column in the fermenter. At the same time, the maximum cross-sections of flows along the tap -

The branches should be equal to the maximum cross-sectional flows in the adjacent technological branches. In a similar scheme, partial adjustment of the air supply to any fermenter is possible and possible.

The air distribution unit operates as follows.

The initial version: the dampers on all technological pipes are open, on the discharge pipes are closed, the air flow from the blower 3 passes through the distribution chamber 1 and is distributed to the consumer m-fermenters 9-13 by means of technological pipes.

If it is necessary to stop the air supply to the fermenter 13, release the clamp 17 on the process connection 8 and turn the lever 16 by 90 °, the flap 14 closes, the flap 23 opens (due to the interaction of the levers 16 and 27 and taut 28) and The air supply to the fermenter 13 is stopped, and the air supplied to it enters the exhaust pipe 22 at the outlet, acts on the movable element 29 of the exhaust valve and is discharged through the exhaust port 33- (to the atmosphere or exhaust ventilation). Air consumption in this direction does not change, and consequently, air consumption in the remaining directions does not change either.

Laziness m, t, e, the air distribution remains stable. The device works similarly when the air supply to any other or several fermenters is stopped.
