Sample preparation instrument for determining starch content in food

The utility model discloses a sample preparation instrument for determining starch content in food, which comprises a table frame, a plurality of layers of storage racks are arranged on the table frame, and the storage racks are divided by partition plates and sequentially form a top-layer storage rack, a second-layer storage rack and a bottom-layer storage rack from top to bottom; a sample feeding mechanism, a showering mechanism, a vibration suspension mechanism, a water bath mechanism, a heat-preservation stirring mechanism, an iodine solution color developing mechanism, a constant-volume filtering mechanism, a hydrochloric acid neutralizing mechanism, a condensation reflux mechanism, a PH adjusting system, a sample discharging mechanism and a waste liquid collecting mechanism are sequentially arranged on the storage rack from left to right; when the preparation instrument is used, the content of starch in food is measured through the mechanisms in sequence, so that the preparation process of a sample is g
