The article is devoted to solving the problem of stabilizing the flow rate of diffusion juice at the outlet from the buffer tank under conditions of an unstable hydrodynamic mode of operation of the diffusion apparatus in sugar production. The existing system does not provide effective stabilization of the juice consumption in case of significant fluctuations in the level and situations arise when the buffer tank is empty or overflowed. A digital control system is proposed that improves the dynamic accuracy of juice flow stabilization due to digital correction according to the integral law of setting the flow regulator according to filtered (smoothed) level values and including proportional, differential components in the correction algorithm when the level leaves the “smooth” control area. The effectiveness of the digital control system is confirmed by mathematical modeling in various modes.

The work presents the scientific basis for the recognition of small specific parts and finished products on a thin gas layer. The proposed principle is based on the use of the interlayer as a carrier and recognizing the main element of the pneumatic system. The purpose of the work is to substantiate the possibility of increasing the production of high-quality piece food production through the introduction of modern automated devices. Together with the design features of the working surfaces of the devices, the creation of universal pneumatic equipment is ensured. The developed equipment is able to successfully solve the problems of moisture removal, sorting, rejection, orientation of the subject of production. The description of the recognition principle is given. The synthesis of elements of the pneumatic system of the type "pneumatic chamber-working surface of the device-thin gas layer-product" showed that they are interconnected. At the stage of synthesis of elements of the pneumatic system and their structural classification, it was possible to unite the characteristic specifics of the described pieces of food industry with the design features of the devices and the operations implemented on them. The presented device schemes have versatility, multifunctionality, ability to manipulate specific pieces, when switching from one standard size of parts to another.
