Automatic negative pressure fruit juice concentrating machine

Abstract

The invention discloses an automatic negative pressure fruit juice concentrating machine, which realizes negative pressure concentration and solves the problem that the quality and taste of hot concentrated fruit juice are influenced due to long time and high pot bottom temperature. The automatic negative pressure fruit juice concentrating machine comprises a juicing device and a negative pressureconcentration device. A juicer of the juicing device is provided with a fruit storage funnel container, and the lower part of the juicer is provided with a fruit juice container. The negative pressure concentration device comprises a concentration cabinet, a heat exchanger, a negative pressure pump and a chip control board, wherein the concentration cabinet is internally provided with a pluralityof electric heat-conducting plates which are adjacent longitudinally and form reverse tilt angles mutually; the bottom of the concentration cabinet is provided with a concentration container; and theconcentration container is internally provided with a concentration measurer and a liquid level sensor. One end of a guide pipe is provided with a filter net and then the guide pipe extends into thefruit juice container; the other end of the guide pipe communicates with a liquid adjusting valve through the heat exchanger to supply fruit juice in the concentration cabinet; the negative pressure pump is arranged on the concentration cabinet; and an air suction pipe of the negative pressure pump communicates with the interior of the concentration cabinet, and an air exhaust pipe communicates with the interior of the heat exchanger.

Description

[0001] 1. Technical field [0002] The invention relates to the technical concentration field of fruit juice production, in particular to an automatic negative pressure fruit juice concentrator. [0003] 2. Background technology [0004] The price is generally very low when the fruit is ripe, but the concentrated fruit juice is easy to store and transport, so the price is very high. For example, the economic benefits can be doubled after pears are made into pear paste, but it is very troublesome for ordinary fruit farmers to concentrate juice or boil pear paste. Evaporation and concentration of fruit juice is an important link in the process of concentrating fruit juice. For example, most pear juice evaporation and concentration equipment uses a pot to directly heat pear juice to evaporate and remove water to make pear cream. Excessive bottom temperature will affect the quality of concentrated juice. Therefore, how to reduce the boiling time as much as possible and avoid the l...
