Device and method for analyzing flavor of pig feed

Abstract

The invention discloses a device and a method for analyzing the flavor of pig feed. The device comprises a data acquisition device and a computer, wherein the data acquisition device comprises a microprocessor, a sample chamber, an air chamber, a gas sensor array and a first air pump; an upper communicating pipe and a lower communicating pipe are arranged between the sample chamber and the air chamber; the air chamber is connected with the first air pump through a first air inlet pipeline; a first solenoid valve and an activated carbon filter screen are arranged on the first air inlet pipeline; an air outlet and a second air pump are arranged on the upper communicating pipe; an air outlet solenoid valve is arranged on the air outlet; the gas sensor array is arranged in the air chamber. Volatilized gas of the pig feed is detected through the gas sensor array, the microprocessor is used for sampling a response signal generated by the gas sensor; the computer is used for processing the sampling value; the dynamic classification parameter delta is calculated through a nonlinear stochastic resonance algorithm and a nonlinear self-calibration dynamic classification model, so that the flavor of the pig feed is judged. The device and the method can distinguish flavors of different kinds of the pig feed.

Description

technical field [0001] The invention relates to the technical field of pig feed detection, in particular to a pig feed flavor analysis device and method. Background technique [0002] Animals use their senses of smell and taste to identify the nature of food, regulate appetite, and control food intake. The senses of smell and taste of pigs are very sensitive. Generally, after a certain flavor of feed is identified, it is not easy to change the feed, which can ensure the market share. These ingredients are finally included in the compound feed ingredients. Barley releases tannin factors when crushed. Rapeseed meal, linseed meal, cottonseed meal, etc. will cause acrid or bitter taste, meat meal, blood meal, meat and bone meal, etc. will cause odor, corn bran Rancid gas caused by bran, rice bran, etc., bitterness caused by brewer's yeast, etc. Feed additives, such as Ca, P, Cu, Fe, Mn, Zn and other minerals, vitamin B, pantothenic acid, choline, etc., Lys, DL-Met, L-Thr and o...

Problems solved by technology

[0004] The purpose of the present invention is to overcome the current technical problem of being unable to distinguish the flavors of different types of pig feeds, and to provide a method for analyzing the flavors of pig feeds, which can distinguish the flavors of different types of pig feeds, which is convenient for feed manufacturers to identify pig feed products. Analyze and manage the flavor, improve the product according to the pig's preference, and improve the production efficiency of the enterprise
