Detailed introduction
　　I. Definition of Small Extraction Tank
　　The extraction tank is more and more widely used in our industrial production. Now the extraction in the laboratory has changed from manual to automatic. The amount of experiment has changed from milliliters to tens of liters. This can directly enlarge the production. This kind of extraction tank is generally called small extraction tank. According to the size of each manufacturer, the specific capacity of the extraction tank is different. Here we call the extraction tank with capacity below 500 L. Therefore, as the name implies, a small extraction tank is a kind of extraction tank with small volume. Small extraction tank is a kind of multi-functional stainless steel extraction tank, which is also commonly used.
　　II. Composition Characteristics of Small Extraction Tanks
　　A complete set of small extraction tank equipment includes extraction tank, defoamer, condenser, cooler, oil-water separator, eyecup, filter, extraction pump, cylinder. Configuration accessories: CIP cleaning automatic rotating spraying ball, temperature gauge, pressure gauge, explosion-proof viewing hole lamp, viewing mirror, quick-opening feeding inlet and outlet. The small extraction tank has the advantages of high efficiency, convenient operation and high automation. The equipment can be used in atmospheric pressure, water decoction, wet soaking, heat reflux, forced circulation infiltration, aromatic oil extraction and organic solvent recovery in Chinese medicine, food and chemical industries. Especially, dynamic extraction or countercurrent extraction has better effect, shorter time and higher liquid content. Extraction cans are often used in Chinese herbal medicine, glucose, animal protein, plant protein, wine-making, starch, chemical industry, health food, alcohol recovery in pigment industry, etc. The inner cylinder of the equipment is made of imported SUS304 and SUS316L. Polishing treatment, generous appearance, clean inner surface without dead angle.
