Food energy tester

Abstract

The invention discloses a food energy tester. The food energy tester comprises an energy tester body lower portion, a support, a body upper portion, a conical bottle, a cover, an electronic thermometer, a plug, a clamping device, a temperature sensor and a box. The body lower portion is arranged at the bottom of the box, the support is arranged in an inner hole of the body lower portion, and the body upper portion is arranged above the body lower portion; the cover is arranged at the top of the body upper portion, and the clamping device is arranged at the lower end of the cover; the conical bottle is arranged in the middle of the cover through the clamping device and located in a through hole of the body upper portion; the plug is arranged at a bottle opening of the conical bottle; the electronic thermometer is arranged on the plug; the temperature sensor is arranged on the inner wall of the box, and the box is provided with a box cover and a handle. By adopting the food energy tester, food energy testing experiments are conducted, the situation can be effectively avoided that heat which is released during food burning is dissipated into the environment, the experiment operation is simple, and the obtained experiment result is more accurate.

Description

technical field [0001] The invention relates to the technical field of food energy measurement, in particular to a food energy measuring instrument. Background technique [0002] In the junior high school "Biology" textbook, there is a student inquiry experiment of "determining the energy stored in a certain food". In this exploratory experiment, discarded pop cans were used in the teaching materials and converted into experimental heating devices. In the process of implementing the exploratory experiment teaching, it was found that the heating device converted from discarded pop cans has good thermal conductivity and poor sealing performance, which will cause most of the heat released when the food is burned to be lost to the surrounding environment; at the same time, when the food is burned and heated If the mouth of the Erlenmeyer flask is not blocked, a large amount of heat will be lost; and an ordinary thermometer is used to measure the temperature of the experimental ...

AI Technical Summary

Problems solved by technology

In the process of implementing the exploratory experiment teaching, it was found that the heating device converted from discarded pop cans has good thermal conductivity and poor sealing performance, which will cause most of the heat released when the food is burned to be lost to the surrounding environment; at the same time, when the food is burned and heated If the mouth of the Erlenmeyer flask is not blocked, it will also cause a lot of heat loss; there is also an ordinary thermometer used to measure the experimental water temperature, which is greatly affected by the surrounding environment, and the reading data is not accurate enough

Due to the lack of appeal, the experimental results obtained in this textbook experiment are inaccurate, and it will also cause students to misunderstand the energy stored in food
