DOI: 10.21443/1560-9278-2020-23-3-224-236 Known methods for calculating the working bodies o f tank equipment, for example, those described in9 (Shevchuk et al., 2020), allow effective selecting and calculating o f the working blades o f vertical meat mixers. A feature o f vertical-layout meat mixers is their versatility, that is, the possibility o f using these machines both for mixing minced meat, and for efficient maceration o f medium-sized and small-sized pieces meat raw materials by massaging it with universal multi-purpose blades or by means o f a simple readjustment, which consists in replacing the mixing working bodies with massaging ones. Due to this versatility, such machines are often positioned precisely as meat massagers, considering the maceration o f meat raw materials to be their main technological function (Shugurova, 2010). In our scientific institution, a series o f projects has been performed to create universal vacuum meat mixers with the possibility o f using them as meat massagers (Verbytskyi et al., 2019). For small enterprises and workshops for the production o f meat products, the Ya5-FFV unit with a working bowl o f 0.08 m3 is intended. For medium-sized enterprises, a Ya5-FSG vacuum machine with a working bowl o f 0.15 m3 is designed. Its design is as follows (Fig. 2). A cylindrical bowl (2) with working bodies (7), closed by a sealed cover, is attached to the frame o f the welded structure (1) by semi-shafts. The unit consisting o f an electric motor, a V-belt transmission and a gearbox is the drive o f the installation (3). The shaft o f the working bodies is connected to the output shaft o f the gearbox. A pump-compressor (4) and a vacuum line with a pressure gauge and a vacuum relief valve located in the upper part o f the bowl are intended to evacuate the working cavity. The control functions o f the machine are carried out using the control panel (5). A mechanism (6) is provided for turning and overturning the bowl; it is a worm gear pair with a manual drive. A universal vacuum appliance for mixing / massaging raw meat works as follows. The raw meat to be processed and other components provided by the formulation are loaded into the working bowl, the lid is closed, the unit drive is turned on, and then, the pump- compressor o f the vacuum system. When the technological processing is completed, it is necessary to turn off the drive o f the installation and the pump-compressor, open the drain valve, open the lid, turn the bowl and unload the product into the prepared transport container. 4 3 7 5 2 1 6 Fig. 2.
