Fermented crude pear juice production system

Abstract

The invention discloses a fermented crude pear juice production system. The system comprises a control part, a pear juice squeezing part, a circulating concentration part and a draw solution circulating part, wherein the pear juice squeezing part comprises a disinfection tank, a soaking pool, a transmission groove and a squeezing filter, and is used for cleaning and squeezing pears; the circulating concentration part comprises a circulating tank and a separation tank; the squeezed pear juice is circulated in the circulating tank and the separation tank until the sugar degree and flavor substance content in the pear juice achieve required values; the draw solution circulating part comprises an evaporator and a plurality of parallel drawing tanks, and is used for providing and regenerating draw solution; and the control part comprises a PLC controller, an input end, a signal reception end and a signal output end, and is used for automatically controlling the system. The production systemutilizes a positive permeable membrane technology, so that the moisture content in the pear juice can be reduced without changing the physicochemical properties of ingredients in the pear juice and the aims of concentrating the pear juice and strengthening the flavor are achieved.

Description

technical field [0001] The invention belongs to the technical field of beverage preparation, and in particular relates to a production system of fermented pear juice. Background technique [0002] Pears have been praised as "the ancestor of ginkgo" since ancient times. It is sweet and slightly sour, cold in nature, and non-toxic. Perry wine is a kind of beverage wine brewed from fresh pear juice. Perry wine contains 18 kinds of amino acids needed by the human body, 7 of which are necessary for the human body but cannot be synthesized by itself; in addition, it also contains potassium and sodium. , calcium, magnesium, copper, zinc, iron, manganese and other minerals and trace elements. [0003] Before the fresh pear juice is fermented, the fresh pear juice needs to be processed to increase the sugar content and the content of flavor substances of the pear juice, that is, the original pear juice needs to be prepared earlier. Raw pear juice is generally obtained through the f...

Problems solved by technology

[0009] Using this method will cause denaturation of cold-sensitive substances during the cooling process, thereby reducing the content of flavor substances in pear juice; and the separation of ice crystals will cause loss of pear juice. At the same time, the investment and operation costs of freezing equipment are high and the economic benefits are low.
