Abstract:
To optimize the performance of separating equipment to process tomato pomace in terms of separation rate and degree of separation cleanliness of tomato seeds and skin, a double-action pomace-separation test apparatus was developed. Core operating components in this design included a centrifugal screening device, inclined plate sedimentation unit, and a feeding system. The combined modular design showed installation and replacement compatible with the test apparatus, while structure and motion parameters of the operating components were fully adjustable. The relationship model between various factors under different working conditions and quality indices (such as the separation rate and degree of separation cleanliness) was established, and flow field distribution in the settling chamber was acquired. Verification test results showed that the test apparatus exhibited a stable performance and parameters were easy to adjust. The degree of pomace separation cleanliness (64% to 98%) was significantly affected by feed rate of the centrifugal screening device (F = 5329.00, P < 0.01), speed (F = 841.00, P < 0.05) and angle (F = 1225.00, P < 0.05) of the scraper, and interaction of feed rate and scraper angle (F = 225.00, P < 0.05). This test apparatus design provides parameter basis to optimizing the design of separating equipment based on double-action that can be applied to tomato pomace processing.
