Problems solved by technology

[0003] In the prior art, when it is necessary to detect the water activity of different objects to be inspected, the staff needs to frequently open the column cover to replace the object to be inspected. Only a single moon cake can be tested at a time, and the operation steps of opening the column cover are cumbersome, making The use of the tester is not convenient enough, so it is necessary to study a simple and efficient high-efficiency tester for water activity of ice skin mooncakes and its test method

Abstract

The invention belongs to the technical field of testers, particularly relates to an efficient tester for water activity of snowy mooncakes and a testing method thereof, and aims to solve the problems that when water activity of different objects to be detected needs to be detected generally, a worker needs to frequently open a column cover to replace the objects to be detected, only a single mooncake can be tested at a time, the operation steps of opening the column cover are tedious, and the testing efficiency is high. In order to solve the problem that the existing tester is inconvenient to use, the invention provides the following scheme: the tester comprises an activity instrument, one end of the activity instrument is provided with a test box, the outer wall of one side of the test box is rotatably connected with a plurality of first cover plates, two ends of the inner wall of the test box are provided with a plurality of slots, and the inner walls of the slots are provided with loading boxes. The first cover plate is arranged on the inner wall of the through groove, the mooncakes in the loading boxes can be tested through the first cover plate by arranging the testing mechanism in the moving box, the mooncakes in different loading boxes can be tested by arranging the moving box to be clamped at different heights of the testing box, and the testing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of testers, in particular to a high-efficiency tester for water activity of snowy mooncakes and a test method thereof. Background technique [0002] The water activity meter is mainly used to reflect the effective moisture, product stability and microbial reproduction ability that microorganisms can utilize or participate in chemical reactions under food equilibrium. The working principle of the water activity meter is to place the sample to be tested in a sealed space, and under the condition of maintaining a constant temperature, the vapor pressure of the sample and the surrounding air is balanced, and then the vapor pressure of the gas space is used as the value of the vapor pressure of the sample. . At the same time, the saturated vapor pressure of pure water is constant at a certain temperature, so the water activity of the tested food can be calculated through the formula defined by water activity. W...
