Food extraction device capable of recycling solvent

Abstract

The invention discloses a food extraction device capable of recycling a solvent. The food extraction device comprises an extraction tank, a filter tank and an evaporation tank which are sequentially arranged from top to bottom, wherein a stirrer is arranged above the extraction tank, and a feed opening is formed in the bottom end of the extraction tank; a slag fetching hole is formed in the side wall of the filter tank, the slag fetching hole is provided with a sealing cover, a group of filter holes are formed in the bottom end of the filter tank, and the upper ends of the group of filter holes are provided with a piece of filter cloth; the side wall of the evaporation tank comprises an inner layer and an outer layer, the inner layer and the outer layer collectively form an inner cavity, the outer layer is provided with an air inlet pipe and an air outlet pipe, the inner layer is provided with a suction filter pipe, the outer end of the suction filter pipe is connected with a suction filter pump, the inner layer is also provided with a circulating pipe, the end part of the circulating pipe extends into the extraction tank, and the circulating pipe is provided with a condenser, and a discharging hole is formed in the bottom end of the evaporation tank. By adopting the food extraction device, the technical defects that the food extraction efficiency is low, the operation is complicated and the material is wasted can be overcome. The food extraction device is high in efficiency, simple to operate and capable of saving materials.

Description

technical field [0001] The invention belongs to the field of food extraction, and in particular relates to a food extraction device capable of recycling solvents. Background technique [0002] Food extraction refers to the process of transferring soluble matter in food to a suitable solvent, so as to realize the extraction of different components of food, such as oil extraction of soybean, peanut kernel, corn germ, etc. The food extraction process usually includes the following steps: the solvent is transferred from the bulk phase to the solid surface; the solvent is transferred from the solid surface to the void in the solid; the soluble matter in the solid is dissolved in the solvent; the soluble matter diffuses through the solvent in the solid to the solid surface; the solute diffuses from the solid surface into the solvent phase. [0003] At present, when food is extracted, the food is usually added to the extraction tank at one time, and then the solvent is added to th...
