Abstract

The invention relates to a simple fragrance smelling device suitable for evaluating flavors and fragrances. The simple fragrance smelling device is characterized in that the simple fragrance smelling device comprises an inner sleeve pipe and an outer sleeve pipe, which are sheathed together and can be rotated with each other, wherein an air inlet and an air outlet are formed in the inner sleeve pipe, and a handle is arranged on the inner sleeve pipe and extends out of the end surface of the outer sleeve pipe, a fragrance smelling hole and a sample bottle connecting port are formed in the outer sleeve pipe, the handle on the inner sleeve pipe can be rotated, when the air inlet of the inner sleeve pipe is coincided with the sample bottle connecting hole of the outer sleeve pipe to be communicated, the air outlet and the fragrance smelling hole are completely closed, when the air outlet is coincided with the fragrance smelling hole to be communicated, the air inlet and the sample bottle connecting hole are totally closed. When the fragrance smelling device is used for performing the fragrance evaluation, the sample preparation process is not needed, the sample is not contacted during evaluation and can be recycled after evaluation, the sample loss during evaluation is completely eliminated, and the sample contamination caused by immersion sampling is avoided; besides, the simple fragrance smelling device is simple in operation, convenient to disassemble, easy to clean and low in cost and can be repeatedly utilized.

Description

technical field [0001] The invention relates to a simple scent smelling device used for smell evaluation of flavors and fragrances. Using the device to carry out the smell evaluation of flavors and fragrances samples can reduce the preparation process of evaluation samples and the loss of samples. Background technique [0002] The sensory evaluation of flavors and fragrances is an indispensable and important process for understanding the quality of flavors and fragrances and making corresponding deployments. When evaluating the olfactory characteristics of flavors and fragrances, two methods are usually used to prepare the samples to be evaluated. [0003] One is usually to put a certain amount of absorbent cotton (used as a fragrance carrier) in a wide-mouthed container, and take a certain amount of flavor and fragrance samples and add it dropwise to the absorbent cotton, then seal the jar with a stopper, and balance it for a period of time to make the fragrance After the ...
