Sample concentration apparatus used for food safety detection

Abstract

The invention discloses a sample concentration apparatus used for food safety detection. The sample concentration apparatus comprises a pedestal, an outer tank is arranged at an end face of the pedestal, a top board is arranged at a top end of the outer tank, a hot-air blower is arranged in the top board and positioned at one side of the end face of the pedestal, an outlet pipe is arranged at a gas outlet end of the hot-air blower, one end of the outlet pipe passes through the side wall of the outer tank, a connecting device is arranged, several air delivery pipes are arranged at the top of the connecting device in a coupling mode, the top of several air delivery pipes passes through the top board and is extended to an upper part of the top board, exhaust nozzles are arranged in the coupling mode, several exhaust nozzles are arranged at a displacement box fixedly connected with an end surface of the top board, a protection tank is arranged at the bottom of the top board and positionedin the outer tank, and a rotation rod connected with the end surface of the pedestal in a movable mode is arranged below the protection tank. The sample concentration apparatus has the beneficial effect that the structural design of the apparatus is simple and reasonable, single air passage control replaces air passage integral control, the apparatus is adapted to different requirements of different samples on gas volume, and is suitable for popularization.

Description

technical field [0001] The invention relates to the technical field of food testing equipment, in particular to a sample concentration device for food safety testing. Background technique [0002] In the field of food safety analysis, in order to obtain the residual amount of the target compound, the sample to be tested needs to be pre-treated. The existing sample concentrator has a complex structure, a large volume, a large footprint, a slow drying speed, and a long time. It is cumbersome to adjust the rise or fall of the blowing head systematically, and the operation is cumbersome, which cannot meet the analysis requirements of a large number of samples on site. It is urgent to design a sample concentration device for food safety testing. [0003] Aiming at the problems in the related technologies, no effective solution has been proposed yet. Contents of the invention [0004] In view of the problems in the related art, the present invention proposes a sample concentrat...
