Vegetable concentrates contain in their composition dietary fibers, microelements, color-forming substances, allowing to use them as a replacer of a main substance in food products rather successfully. The authors propose a way of vegetables processing into vegetable semi-products. Vacuum drying of vegetable pressed skins using vibration is provided. The method of vegetables processing into vegetable concentrates on an example of carrot provides raw material separation in juice and pressed skin with further separate processing of each component. For realizing the proposed method, a technological production line of concentrates of vegetable raw materials, including developed and studied equipment: vacuum evaporating apparatus with a device for heating and mixing, vacuum vibration dryer has been developed. Experimental studies of a swelling degree, solubility and reproduction of vegetable pressed skins have proved an advantage of drying raw materials under the influence of vibration that confirmed the choice of process parameters. Vegetable pressed skins at using vibration and vacuum have a swelling degree by 120…170 % more than at the convection drying regime
