Continuous Eucommia jelly freeze-out device

Abstract

The invention discloses a continuous gutta-percha freezing-out device which comprises a freezing-out bucket with a freezing water inlet pipe, wherein the freezing water inlet pipe is connected with a plurality of heat exchange pipes with baffles and penetrates out of the freezing-out bucket through a freezing water return pipe, the heat exchange pipes are provided with fins and are vertically arranged, and a freezing water pipe is connected with a water hammer vibration exciter; the freezing-out bucket is provided with a to-be-frozen-out liquid inlet and an overflow reflux pipe; a spiral conveyer is arranged on one side of the bottom of the freezing-out bucket; an inverted conical structure is arranged on the other side of the freezing-out bucket and penetrates through a solid-liquid separation bucket through an axial-flow pump to be connected with a sieve mesh bucket; a bottom outlet of the sieve mesh bucket is connected with a spiral juicer; both the sieve mesh bucket and the spiral juicer are arranged in the solid-liquid separation bucket, and the solid-liquid separation bucket is connected with the freezing-out bucket. According to the device, the technical difficulties of low heat transfer coefficient and non continuous production in a gutta-percha freezing-out process are overcome. The device is reasonable in design, safe and reliable, relatively low in cost and convenient for large-scale industrialized production.

Description

technical field [0001] The invention relates to a continuous eucommia jelly freeze-out device. Background technique [0002] Eucommia gum is a new functional material with multiple uses and has important application value. It is usually extracted from the plant tissue of Eucommia Eucommia by using non-polar solvents such as petroleum ether. Since Eucommia gum is easily soluble in hot petroleum ether and other non-polar solvents have very low solubility in non-polar solvents such as cold petroleum ether. Therefore, after freezing and cooling the solution of Eucommia gum after extraction, Eucommia gum can crystallize and separate out, but because the crystal density of Eucommia gum is slightly greater than that of solvent petroleum Ether, suspended and sinking, so it is very easy to form a heat transfer stagnant layer on the heat transfer surface, and there is always a sol layer attached to the precipitated crystal glue layer during the freeze-out process, the heat transfer co...

[0002] Eucommia gum is a new functional material with multiple uses and has important application value. It is usually extracted from the plant tissue of Eucommia Eucommia by using non-polar solvents such as petroleum ether. Since Eucommia gum is easily soluble in hot petroleum ether and other non-polar solvents have very low solubility in non-polar solvents such as cold petroleum ether. Therefore, after freezing and cooling the solution of Eucommia gum after extraction, Eucommia gum can crystallize and separate out, but because the crystal density of Eucommia gum is slightly greater than that of solvent petroleum Ether, suspended and sinking, so it is very easy to form a heat transfer stagnant layer on the heat transfer surface, and there is always a sol layer attached to the precipitated crystal glue layer during the freeze-out process, the heat transfer conditions are extremely harsh, and the total heat transfer coefficient is very small; On the other hand, continuous production is the only way to achieve large-scale production of Eucommia gum freeze-out

[0003] Therefore, the existing devices and equipment cannot solve the technical problems of slow cooling during the crystallization process of eucommia gum, and the precipitated eucommia gum forms a flocculent suspension in the solution, which is difficult to separate and continuous production. Water can increase the heat transfer coefficient and speed up the process of freezing and thawing, but it also has the disadvantages of troublesome separation of ice and water, high energy consumption, and inability to achieve continuous production. Therefore, the existing technology cannot meet the needs of industrialized production of Eucommia gum
