Description

Technical Field

[0001] This utility model relates to the field of moisture detectors, and in particular to a portable rapid moisture detector for tobacco leaves. Background Technology

[0002] Testing during the tobacco leaf procurement process is a core line of defense for ensuring raw material quality and fair transactions. Among these tests, moisture content testing is extremely important, and its necessity is reflected in the following key areas:

[0003] 1. Prevent mold and microbial growth:

[0004] Free water in tobacco is a key medium for microbial reproduction, and water activity directly affects the risk of mold growth; reduced water activity can inhibit microbial growth and harmful chemical reactions, ensuring safe storage.

[0005] 2. Maintaining processing quality and physical properties: Moisture content directly affects the elasticity, toughness, and combustibility of tobacco leaves.

[0006] Excessive moisture content increases the stickiness of tobacco leaves, reduces their filling power, and darkens their color.

[0007] If the moisture content is too low, the tobacco leaves will be brittle, have a low yield of shredded tobacco, and reduced filling power.

[0008] The moisture content of finished cigarettes must be strictly controlled between 11.0% and 13.5%, otherwise it will lead to uneven combustion, distorted aroma, or increased irritation.

[0009] 3. Eliminate economic losses and compliance risks:

[0010] During the acquisition process, unscrupulous individuals profit by injecting water to artificially increase the weight of tobacco leaves. A moisture content exceeding the standard by just 1 percentage point can cause significant economic losses of tens of thousands of tons of tobacco leaves.

[0011] In the warehousing process, uncontrolled moisture can lead to mold or even spontaneous combustion, directly affecting the safety of corporate assets.

[0012] Moisture analyzers are needed to test the moisture content of tobacco leaves. However, existing moisture analyzers cannot perform comprehensive testing on large piles of tobacco leaves, and they occupy a fixed amount of space, making them inconvenient to carry.

[0013] This invention addresses these issues by proposing a portable rapid moisture analyzer for tobacco leaves. The analyzer is designed to solve the aforementioned problems by allowing for flexible folding and storage, effectively reducing space occupation and facilitating portability. The extendable detection rod enables comprehensive testing of tobacco leaf piles. Utility Model Content
