Problems solved by technology

However, in order to identify the pressure resistance of varieties, a special measuring device is required. Using the hardness tester in the prior art to measure pressure, due to the influence of fruit maturity, shape and structure, hundreds of data are needed to measure the pressure resistance of a variety
At present, the more practical pressure measuring device is the device for measuring the pressure resistance of tomato fruit made by Zhao Youwei, Ren Chengwei, etc. When measuring the pressure resistance of a variety, at least 30 fruits are needed to calculate the average pressure resistance of a certain variety, and the pressure resistance is affected by the size, shape, structure, and maturity of the fruit, and it is inconvenient to observe (if the back is broken, the not observed)

Abstract

The invention relates to a device for measuring the pressure resistance of processed tomatoes, in particular to a device for measuring and comparing the pressure resistance of different varieties of processed tomatoes. The device comprises a hollow shell, wherein a weighing bench scale is arranged in the hollow shell, a fruit vessel with an opening at the upper end is arranged on the weighing bench scale, a sliding pressure plate capable of moving up and down is arranged at the opening of the fruit vessel, the sliding pressure plate is adaptive to the opening of the fruit vessel in shape and size, a sand cushion or a water cushion is arranged under the sliding pressure plate, a pressing device is arranged above the sliding pressure plate, the pressing device acts on the sliding pressure plate downwards to enable the sliding pressure plate to move downwards. The device has simplicity in operation, is economic and practical, is an effective device for measuring the pressure resistance of different varieties of processed tomatoes, and can improve the measurement efficiency.

Description

technical field [0001] The invention relates to a device for measuring the pressure resistance of processed tomato fruits, in particular to a device for measuring and comparing the pressure resistance of processed tomatoes of different varieties. Background technique [0002] Xinjiang is one of the world's three major tomato production and processing bases, with an annual output of 7.5 million tons of fresh tomatoes and 1 million tons of processed tomato paste. After the tomato fruit is ripe, it is often broken due to impact and extrusion during the process of mechanical harvesting, transportation, and stacking. Cracked fruit not only reduces the commodity value, but also perishes easily. The loss of tomatoes from the field to the factory due to rot reaches 20% to 40%, which not only affects the interests of farmers and enterprises, but also poses hidden dangers to product quality and safety. The main cause of tomato rot is that most domestic varieties are not resistant to ...
