番茄酱加工后皮渣分离试验装置的设计

Testing Apparatus Design for Tomato Pomace Separation after Tomato Sauce Processing

摘要:

为优化基于双作用的加工番茄酱后皮渣分离装备性能，进一步提高番茄籽与皮的分离率和分离净度，设计了以离心筛分装置、斜板沉降装置和喂入系统为核心工作部件的双作用皮渣分离试验台。采用可组合的模块化结构，试验台更换安装方便，工作部件的结构参数和运动参数完全可调，可建立不同工况下各因素与分离率、分离净度等质量指标之间的关系模型，获得沉降室流场分布规律。验证试验结果表明，试验台工作性能稳定，参数调整方便，离心筛分工作部件的喂入量（F=5329.00，P<0.01）、刮板转速（F=841.00，P<0.05）、刮板角度（F=1225.00，P<0.05）、喂入量和刮板角度的交互作用（F=225.00，P<0.05）对皮渣分离净度（64%~98%）影响显著。本试验台为加工番茄酱后皮渣双作用分离装备的优化设计提供参数依据。

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.
