A fruit moisture detection device

Abstract

The invention discloses a fruit moisture detection device. The device is characterized by comprising a measuring seat, a water loss cylinder, a bracket, a first heater, a water vapor outlet pipe and asealing cover, wherein the water loss cylinder is arranged on the upper surface of the measuring seat, a detector for weighing the weight of the water loss cylinder is arranged on the measuring seat,the water vapor outlet pipe is arranged on the lower portion of the peripheral wall of the water loss cylinder, the water loss cylinder is located below the water vapor outlet pipe to form a water containing cavity, the bracket is slidably arranged on the inner side wall of the water loss cylinder in the vertical direction, and a lifting part is arranged in the water loss cylinder; the bracket isfurther provided with a pressing and grinding piece used for smashing fruits, the first heater is arranged on the upper surface of the measuring seat, and the sealing cover is detachably connected toan opening in the top end of the water loss cylinder in a sealed mode. When moisture in fruits is evaporated, a specified amount of external water is introduced to dilute the moisture in the fruits,so that impurities in the moisture of the fruits are relatively reduced, the temperature required for drying the fruits is reduced, decomposition of other components in the fruits is reduced, and thedetection accuracy is improved.

Description

technical field [0001] The invention relates to the field of fruit and vegetable quality detection, more specifically, it relates to a fruit moisture detection device. Background technique [0002] With the improvement of people's living conditions, fruits have become an indispensable food every day. We could still eat natural good fruits before, but with the changes of the times and the expansion of human demand, the market's The quality and safety of fruits have also attracted people's attention. Therefore, fruit detection is also essential. Fruit testing can be divided into two categories: safety testing and quality testing, mainly including pesticide residue testing, fruit hardness testing, fruit sugar content testing, fruit acidity testing and fruit moisture testing. [0003] For the detection of fruit moisture, the fruit is usually put into a drying oven to evaporate the water in the fruit and vegetables, and the moisture content of the fruit can be obtained by calcu...

Problems solved by technology

[0004] However, the water in the fruit is fully combined with the tissue in the fruit, and the water contains a lot of impurities such as sugar, which causes the boiling point of the water in the fruit to rise, and a higher temperature is required when drying the fruit. This can easily cause the decomposition of other components in the fruit, resulting in increased weight loss of the fruit, resulting in inaccurate test results
